المستخلص: يتعرض الحليب للعديد من الملوثات الفيزيائية والكيميائية والبيولوجية وذلك بسبب طرق الانتاج واسلوب النقل وعمليات التسويق ومن هذه الملوثات المعادن الثقيلة والرقم الهيدروجيني ودرجة الحرارة والبكتيريا. وقد صممت الدراسة الحالية لفحص عينات للحليب الخام التي جمعت | Milk is subjected to various physical, chemical and biological pollutants duo to producing, transporting and marketing processes such as certain heavy metals, pH, temperature and bacteria. The current study was designed to examine fresh milk samples were collected randomelly at early morning from six different locations at a rate of once each month during study period which commenced in October 2013 and ended in march 2014 and powder milk brands which were examined again for six months as in case of fresh milk where these milk brands were collected from local markets each month. The results of heavy metals showed that : • The investigation of Lead content in raw milk revealed that the highest mean value (1.801±0.311 ppm) was scored in Abo - Ghraib sample and the lowest mean value (0.941±0.104 ppm) was observed in Ghazaliya sample. For the Cadmium content in raw milk that the highest mean value (1.532±0.124 ppm) was found in Abo - Ghraib sample and the lowest mean value (0.063±0.044 ppm) was found in Fal'loga. The Copper content in raw milk also investigated and resulted the highest mean value was (0.931±0.092 ppm) in Azizia milk sample and almost similar value (0.931±0.301 ppm) was found in Madain sample while the lowest mean value was (0.308±0.029 ppm) in Fal'loiga sample. The highest mean value of Potassium in raw milk was recorded in two samples in Azizia (9718.8±246.6 ppm) and (9718.3±482.2 ppm) in Abo - Ghraib but the lowest mean value (4156.3±268.3 ppm) was recorded in Essaouira. Regarding Sodium content in raw milk, the results have found that the highest mean value was (2968.8±312.2 ppm) in Essaouira sample while the lowest mean value was (1432.5±156.8 ppm) in Abo - Ghraib. The Chloride content in raw milk samples, the highest mean value was (3053.0±128.6 ppm) recorded in Fal'loga sample and the lowest mean value was (639.0±198.4 ppm) was found in Azizia sample. Analysis of variance of these data showed significant effects (P?0.001) of both sampling sites and collecting months on milk (pb, Cd, K, Na and Cl) contents while analysis of variance of these data reveals no significant impact of sites on milk Cu content (P> 0.05) where no differences were observed between mean value of different collecting sites but shows highly significant (P? 0.001) effects of collecting months.• While powder milk has shown that the highest mean values of Lead (1.225±0.052 ppm) were found in Al - Mudhish brand and the lowest mean value (0.088±0.002 ppm) was detected in Anchor. The highest mean Cd value was (0.184±0.005 ppm) in Nido brand and the lowest mean value was (0.069±0.003 ppm) in Altunsa sample. While the highest mean value of Copper was (1.656±0.254 ppm) in Dielac powder brand and Anchor milk brand had the lowest copper mean value which was (0.767±0.014 ppm). The concentration of Potassium was (9625.0±462.9 ppm) which is the highest recorded in Dielac milk sample and the lowest mean value (3356.8±225.6 ppm) was found in Al - Marai milk sample. While the highest average of Sodium was (2625.0±342.6 ppm) scord in Dielac brand and the lowest average was (1745.0±338.4 ppm) recorded in Al - Marai sample. The highest mean value of Chloride (193.0±41.0 ppm) was recorded in Nido milk brand and the lowest mean value (122.7±22.2 ppm) was found in Altunsa milk sample. However, analysis of variance shows significant differences (P?0.001) between examined milk brands while no such differences were found between these brands (P>0.05) regarding collecting months.From the above results, it seems that the highest content of (Pb, Cd and Cu) are higher than those of standards of the International Dairy Federation (IDF) while contents of (K, Na and Cl) are within the standard requirement according to National Research Council (NRC).Microbial tests of raw milk samples were positive for bacterial growth, as different bacterial species were observed such as Lactobacilli spp. 63.8%, Streptococcus spp. 61.1%, Staphylococcus aureus 44.4%, Escheritia coli 88.8%, Bacillus spp. 72.2%, Salmonella typhi 72.2%, Staphylococcus epidermidis 30.5%, Pseudomonas spp. 47.2%, Micrococcus spp 27.7%, Clostiridia spp. 66.6%, Enterococci spp. 11.1% and K. pneumonia 75% from bacterial contamination of raw milk samples.However, only (11.1%) of the total collected samples of raw milk were suitable for human consumption and (88.9%) unsuitable, indicating that the source of infection or contamination of milk may be due to the animal health, human handler and the environmental factors, e.g., contaminated vessels, polluted water, flies and dust, etc… Obviously, bacterial contamination test of powder milk samples was carried out and negative results were obtained. However, it seems clearly that the opportunity of finding bacterial contamination in powder milk samples may be very rare since milk powder is produced in well designed and modern techniques. Nevertheless, a single bacterial contamination test has indicated to a positive growth of Staphylococcus aureus colonies.

المستخلص: من مجموع مئة عينة سريرية جمعت من مصادر مختلفة شملت الحروق والدم والجروح ومسحات انفية, تمكنت 90 عزلة من النمو على اكار المانيتول الملحي , ومن بينهم 40(44.4 %) عزلة عائدة لبكتريا المكورات العنقودية المنتجة للانزيم المخثر للبلازما و50 (55.5%) عائدة لبكتريا ا | Out of one hundred clinical samples were taken from different sources which include burns, blood cultures, wounds and nasal swabs infections ; 90 isolates developed growth on mannitol salt agar. Among these, 40 (44.4%) were Coagulase positive (Staphylococcus aureus) isolates, 50 (55.5%) belong to coagulase negative staphylococci in which Staphylococcus epidermidis isolates were 30(60%). The pattern of antibiotic susceptibility of Staphylococcus epidermidis isolates to 12 antibotics (Amoxiclav, Ceftazidim, ciprofloxacin, clindamycin, Erythromycin, Gentamycin, Imipenime, Penicillin G, Tetracycline, Rifampin , Methicillin, and Vancomycin) were determined using disc diffusion method. The results revealed that resistance to Penicillin G10 and Amoxiclav (Amoxicillin - clavulanic acid) were 100%, Methicillin were 93%, Erythromycin were 90%, Gentamycin and Clindamycin were 70%, Tetracycline and ceftazidim were 75%, Ciproflaxacin were 60%, Rifampin were30%. 95% of S.epidermidis isolates were sensitive to Imipenim and 5% of them were intermediate resistant, while these isolates showed 90% sensitivity to vancomycin. 19 isolates were multidrug resistance. Minimum inhibitory concentration of S.epidermidis isolates to vancomycin, was determined. The results revealed that (12) S.epidermidis isolates (40 %) were vancomycin resistant, the MIC of them were between 256 ?g\ml and 32 ?g\ml, (4) S.epidermidis isolates (13.3%) were intermediate resistance, the MIC to 3 of them were 16 ?g\ml and the last was 8 ?g\ml. Some virulence factors of VRSE and VSSE were detected including the hemolysin, protease, lipase and urease. The S. epidermidis isolates were produce hemolysin, protases, lipase and urease, were 100%, 100%, 25%, 100% respectively in VRSE, while in VSSE 100%, 100%, 60%, 100% respectively. The isolates were subjected to polymerase chain reaction (PCR) technique in monoplex pattern to amplify resistant incoding gene : the vanA, vanB and autolysine gene aae gene. The results by this study showed that 12 (40%) S. epidermidis isolates gave the implicone size (1030 base pair) of the vanA gene. However the results of MIC and PCR were similar but no any isolates gave product for presence of vanB gene. All S.epidermidis were able to produce implicone size(858bp) of aae gene. The effect of vancomycin resistant S. epidermidis on cell autolysis activity was detected by whole cell autolytic assay.The results revealed that there was significant difference among three isolates, the VSSE isolate (S.epidermidis 22) have the highest autolytic activity in the presence of antibiotic, followed by the VRSE isolate (S. epidermidis 1) and the VISE isolate (S. epidermidis14) which was the lowest autolytic activity with the presence of antibiotic. The result of transmission electron microscope (TEM) showed that the VRSE isolates (S.epidermidis 1) have thicker cell wall followed by VISE (S.epidermidis 14) isolates.However, the VSSE (S.epidermidis 22) didn't showed any cell wall thickening.

Seventy two adult male albino mice were used in this study. The animals were randomly divided into four main groups, the first group was given distilled water (control), while the other three groups were given (100, 300, 500 mg /kg) of crude extract. These main groups were subdivided into three subgroups, according to the period of treatment (2, 4, 6, 8)weeks. Blood samples were collected every two weeks for physiological study, and samples of the liver and testes were collected for histological study. Treating with crude alcoholic of Malva sylvestris led to no significant increase in the mean of the body weight except the concentration (500 mg /kg). There was significantly increase in the liver weight particularly in(500 mg /kg) for eight weeks of exposure, also there was significantly increase in the average of the testes weights treated with Malva sylvestris extract specially in (300, 500 mg /kg) for all periods of treatment compared with control group. Malva sylvestris extract coused significantly decrease in both GOT, GPT. there fore the value of GOT, GPT considers as concentration - period exposure dependent the highest value of GPT was (300 mg /kg) for two weeks (2. 25±228. 04) IU/L compared with control group (3. 03±226. 02) IU/L. and the lowest value of GPT was (500 mg /kg) for eight weeks (4. 52±192. 27)IU/L compared with control group (4. 06±208. 77) IU/L the highest value of GOT in (100 mg /kg) reached (4. 10±63. 00) IU/L for two weeks compared with control group (1. 25±71. 23) IU/L. the lowest value was (2. 77±49. 83) IU/L in (500 mg /kg) with eight weeks comparison with control group (1. 18±69. 02) IU/L. all concentration of Malva sylvestris extract made positive changes in the value of testosterone with all periods of exposure particularly in (300 mg /kg) compared with control group. There were many histopathological alterations appeared in the liver tissue among treated groups which caused by the effects of Malva sylvestris extract represented by congestion, disarrangement of hepatic cords, beginning of necrosis of hepatocytes, infiltration of leukocytes, narrowing of sinusoids, increase the number of binuclei cells, degeneration, appearance of giant cells, all these changes were reversible. Malva sylvestris extract made beneficial histopathological changes in the testes tissue in all treated groups like increase in numbers of ledyig cells specially concentration (500 mg /kg) reached (11.37± 0.80) IU/L with two weeks comparison with control group(5.38 ±0.34) IU/L, and increase in the thickness of the walls of seminiferous tubules specially concentration (500 mg /kg) reached(29.46± 1.39) IU/L with compared with control group(20.52±2.40) IU/L.

المستخلص: Background : Speramax® has been found to play an important role in sperm function characters and males reproductive performance with no studies on its effects on the oocyte maturation and embryonic development in females.Objective : The goal of the thesis is to examine the effect of Speramax ® on oocyte maturation. And to emphasize the effect of Speramax ® on ova quality, embryonic development and newborn. Materials and Methods : Speramax ® treated by oral administration for 1, 2 and 4 weeks. A hundred and twenty six female mice were randomly divided into four groups, the first group was treated without Speramax® with superovulation(SUO) while the second group were treated by Speramax® with SUO and the third group were superovulated only and the fourth group was not treated and spontaneously ovulated (SPO) and considered the control group(thirty two mice). Results : The results indicated that the treatment with Speramax® showed a positive effect on oocytes maturation in vivo. There was a highly significance (p? 0.0001) improvement in number of mature oocytes following treatment with Speramax® in SPO and SUO mice compared with SPO and SUO mice not treated with Speramax®. The embryonic developmental rate after 24 and 48 hours of mating in treated groups with Speramax® was significantly (p? 0.05) higher than those of SPO and SUO mice too.The study showed that the quantity and quality of embryos generated from the treated groups were superior to that of untreated groups.Conclusion : It was concluded that the treatment by Speramax® has a great improvement on oocyte maturation, early embryonic development and embryo grading quality of mice embryos with an increase in the numbers of mice newborn.

These fungi were related to 23 species or isolates, where Aspergillus spp. prevailed over all others (11 species) with CF of 14% for all Aspergilli, Aspergillusniger and Aspergillusflavus showed the highest CF 7.2% and 3% respectively, other Aspergilli represented Aspergillusparvulus (CF 1.6%), Aspergilluscandidus (0.4%), Aspergillusraperi, Aspergillusclavatus, Aspergillusglaucus, Aspergillusornatus, Aspergillussclerotioniger, Aspergillusterreus and Aspergilluswentii were all showed CF of 0.2%.Other isolates fungi from leaves fragments were four morphologically different isolates of Penicillium with 0.4% CF for each. Additionaly, isolates of Cladosporium sp. (2%) and Cladosporiumcladosporoides (0.4%), as well as Cunninghamella sp., Drechsleraaustraliensis, Alternariaraphani, which showed 0.2% CF for each, Paecilomyces variotii (0.6|%), and different isolates of sterile fungi (White and Hyaline colonies) were also obtained. - Study the antagonistic activity of isolated endophytes using dual culture method against five plant pathogenic fungi(Fusarium oxysporum, Fusarium graminearum, Fusarium sp., Macrophomina phaseolinaandRhizoctonia solani)taking into account the percentage of inhibition of pathogenic fungi, results revealed variation of antagonistic activities between endophytes and pathogens. Different cases of antagonism were also appeared ranged from mycoparasitism of the endophytes on pathogens or vice versa, to competition between the two fungi and to the appearance of inhibition zone between them, this result may indicates the affinity of using some isolated endophytes in biological control applications against or controling fungal plant diseases. - Effect of ethylacetate extracts of culture broth of active endophytes shown in the last experiment against two bactria E.coli, S.aureus and the yeast Candida albicans using disc diffusion method, where filter paper discs were imprignated with different concentrations of fungal broth extracts. Results showed variation of inhibitory activity against bacteria with different endophytes, bacteria and conc. of the extract. Regarding the effect onC.albicans and filamentous fungi, most fungal broth extracts showed no inhibitory activity against yeast and no extract as well showed inhibitory activity on filamentous fungi. These results give indication thatbroth extracts contain antibacterial compounds. - Addition of 20% crude fungal broth of some endophytes to the culture medium showed significant inhibitory activity against filamentous fungi which did not respond to broth extracts, percentage of inhibition ranged between 0 - 77.08% and maximum inhibitory activity was shown by Penicillium sp. Isolate. These results give indication that some of crude filtrates contain antifungal compounds. - Analysis of broth extracts of some endophytes using TLC technique showed the content of extract of number of UV illuminated spots isolated on TLC pates having different Rf values, Bioautography showed inhibitory activity of some of these isolated spots against E.coli, S.aureus and the Filamentous fungus F.oxysporum. - Testing the extracellular enzymes activities of isolated endophyles on solid media, enzymes included amylase, lipase, pectinase, laccase, cellulase and protease showed variation in secretion of these enzymes, as well as, no endophytes showed the affinity of secreting all tested enzymes. Results also showed the high affinity of some endpohytes to secrete enzymes that could be use in multiple important applications after separation andcharacterizationof these enzymes.

Air temperature at sampling time was varied from 16°C to 42°C and from 10°C to 34°C, for water temperature at sampling time also. The results of pH values were within the allowable limits, ranging from 7.1in autumn to 8.1 in summer. For EC, the highest value recorded for raw water was in winter with 1338 µs/cm, while the lowest value was in spring with 920 µs/cm. The highest value recorded for drinking water was again in winter with 1330 µs/cm, and the lowest value was 910µs/cm in spring also. The highest value of turbidity recorded for raw water was in winter with 89 NTU and the lowest value was in spring with 26 NTU, while the highest mean value recorded for drinking water was 20 NTU again in winter and the lowest value was 1 NTU in spring. The study showed that the results of TDS values ware ranged from 622 mg/L in spring to 1024mg/L in winter. The highest value of residual chlorine was recorded in summer with 4.5 mg/L; the lowest value was zero mg/L in some of the farthest points of the plants. For sulfates, values were ranged from 289 mg/L in spring to 498.4 mg/L in winter. All the recorded values of chlorides ions for all water samples were within the allowable limits, its values ranged from 98mg/L in summer to156.3 mg/L in winter. For total hardness, the values were exceeding 500mg/L and allowable limits for Iraqi standard criteria. The highest value recorded for raw water was in winter with 520 mg/L and the lowest value was in summer with 351 mg/L, while the highest value recorded for drinking water was again in winter with 516mg/L and the lowest value was 337 mg/L in summer also. For calcium values ranged from 75 mg/L in summer to 135 mg/L in winter. The results of this study showed high levels of lead, cadmium and aluminum in most water samples which collected during study period compared with those that exceeded the acceptable limits provided from the quality control unit and which are considered to have adverse effects on health. For lead, values were found to vary from 0.0030 mg/l in summer to 0.16 mg/l in winter (higher acceptable limits is 0.01 mg/L). While in case of cadmium the values lied between 0.0014 mg/l in winter and 0.015 mg/l in summer (higher acceptable range is 0.0030). However, for aluminum these data were ranged from 0.0062 mg/l in raw water during spring to 0.29 mg/l in drinking water during spring also (higher acceptable range is 0.2). The current results showed an increased in the number of autotrophic bacteria, total coliform, fecal coliform, fecal streptococci, and E. coli during winter season in most study locations as compared to those of the other seasons for both water plants raw and drinking water while the FS values were less than those of other bacterial types for both water plants. The Total plat count results of drinking water were exceed 100 cell/ml, the allowable limit for drinking water, for some samples of both water plants. on the other hand, the TC, FC and E. coli exceeded zero cell/100ml, the allowable limits for drinking water, in many drinking water samples for both water plants

المستخلص: تم جمع خمسين عينة سريرية من قشع مرضى مصابين بذات الرئـــة. وذلك للمدة من تشرين الثاني 2013 ولغاية ايار 2013 من مستشفى ابن البلدي ومستشفى بغداد وذلك لعزل وتشخيص بكتريا Klebsiella pneumoniae التي تعد احدى العوامل المهمة المسببة لاصابات الرئة. واخضعت عينات | Fifty clinical samples collected from sputum of patients who suffered from pneumoniae in Ibn - Balady hospital and the hospital in Baghdad city during the period from November 2012 to May 2013 for the isolation and identification of Klebsiella pneumoniae, one of the important causative agents of infection occurs in the lungs. Sputum samples were subjects to the standard laboratory procedures including identification by biochemical test and VIETK system. The results showed 15 isolates were revealed as Klebsiella Spp, only 10 isolates represented K.pneumoniae, The isolates were examined to produce extracellular toxic complex (ETC) it was found that the isolate named K2 was the higher production. Two method for purification the extracellular toxic complex (ETC) were used, first Aqueous two phase systems, In this method polymer - salt aqueous two phase system was evaluated in crude extract of K. pneumoniae at varying concentration of Dextran T - 150 with 20% with polyvinyl pyrrolidone to final rate (1 : 1) (wt : wt) with 0.2M sodium sulphate. The results showed the best concentration dilution sample given as (4.25 : 0.75) with protein concentration (97.173 mg/ml) which contained ETC in the lower layer and the mice died within 4 hours, while the second method performed by using two step column chromatography, ion exchange DEAE - Cellulose and gel filtration (Sepharose - 4B). In the first step sample given lethal activity by injection to the mice after six hours with protein concentration (55mg/ml), More purification by the second step animal died after 3hours with contain protein (27.75mg/ml). Furthermore, the results of the extracellular toxic complex characterization proved that molecular weight was 39810 Dalton determined through Gel - filtration chromatography using Sepharose 6B gel. The LD50 value of purified toxin was calculated, and the result was (6.52 mg/ml) of toxin.This quantity was found effective to cause killing of 50% of the total toxin treated animals. The biological effect of purified toxin of K. pneumoniae K2 have been examined in vivo by injection of dose (0.5 ml) of purified ETC toxin that contain (10.875 mg/ml ) protein. The final part of the study involved the histopathological changes were noted, abundant mononuclear infiltrate of inflammatory cells with necrosis of lung parenchyma. The second group of mice injected with (0.05 ml of ETC) that contain protein (1.085mg/ml) represented as sub lethal dose Histopathological changes were noted showing near of the normal appearance of alveoli and alveolar space, with presence of congestion of blood vessels. The third group of mice inject with (0.5 ml from Tris - base buffer only) represented control showed normal alveoli and alveolar space with presence of bronchial. In the immunological test the sample ETC examined with ELISA and given IgG titer (189.68+50.70 ng/ml) compared with control (46.78+12.45). This titer of IgG tested with Double immune diffusion assay and gave precipitation line with antigen compared with control.

المستخلص: In recent years, foods produced by genetic engineering technology have been on the world food markets. The biosafety aspects, regulations, and labeling for these foods are still contentious issues in most countries. Thus detection and quantificationof GMOs play crucial role for developing regulations on GM foods.In this study, eighty six non - labeled rice samples from different locals and exported market were analyzed to detect the genetic modification using a DNA based detectionvmethods as, conventional Polymerase chain reaction (PCR), and Real time PCR (RTPCR).The DNA rice samples were extracted by manual C - hexadecyl - Trimethyl - Ammonium - Bromide (CTAB) method and wizard kit method. The result revealed that DNA yield by the two methods is comparable. Rice DNA tends to be of a higher concentration when purified with the CTAB method; however, this particular DNA is more easily to amplify, the optical density (OD) was recorded 1.70 - 1.98 and the concentration of DNA quantified by fluorometer DNA rice samples, ranged from 11 to 50.5 ?g/?l. The DNA rice sample has also been used successfully with the Wizard Genomic DNA Purification Kit, and showed varieties in quality, the OD was recorded 1.65 - 1.95, and the concentration between 4.7 - 43.8 ?g/?l.The rice specific gene (sps gene) was detected by PCR. The results demonstrate that the purity of the extracted DNA in all tested rice samples was sufficiently high for a sensitive PCR analysis and the primer of detected gene appeared clearly at 251pb.Three genes; CaMV 35S promoter, NOS terminator, and insecticide resistant gene Cry1Ac were used to detect of GM rice by PCR, and Real time PCR using oligonucleotide sets targeting to novel genes. The result showed that there was no positive result reaction with conventional PCR, while the outcome of gradient PCR revealed a positive reaction in one sample (Uncle Bens brown) for CaMV35S promoter only. Gradient PCR with 12 replicons for each sample was used for qualitative detection of CaMV35S promoter gene, after optimization of melting temperature and cycles run (45 cycles) , the results appeared positive in the last three grades (63.9, 64.6, 64.9) for CaMV35S promoter, but NOS terminator, and CryIAc were recorded negative results.The result of Real - Time PCR clarified that the CaMV35S promoter specific primer showed strong amplification with Ct, and Tm values were reached into 33.73, 38.63 and 61.55, 62.92 in two samples Uncle Bens brown and Himalayan brown, respectively, whereas NOS terminator gave positive results in four samples Maxims, Laasturiana, Carolin white and Mahatma, and the values Ct and Tm reached to30.87, 30.31, 30.54, 33.75 and 64.53, 64.61, 62.62, 63.87 respectively in comparison with the positive control, while CryI Ac which did not show any positive signal.It was concluded that using molecular methods like Real - time PCR will be useful tool for detecting GM rice such as a part of the approval detection processes because of the rarity of data concerning consumption of GM rice in Iraq.

المستخلص: داء المقوسات الكونديه مرض عالمي الانتشار حيث يصاب معظم الاشخاص ذوي المناعة الجيدة بطفيلي المقوسات الكونديه وغالبا دون ظهور اعراض. ان الهدف الرئيسي لهذه الدراسه هو فهم الفروقات الجنسيه, الهرمونيه والمناعيه في سن البلوغ في الاشخاص الذين لديهم اجسام مضاده نو | Toxoplasmosis is a worldwide disease where most healthy, immunocompetent individuals infected by Toxoplasma are almost asymptomatic.The primary goal of this study is to perceive the hormonal and immunological sex - differences in puberty age who have positive anti - Toxoplasma IgG specific antibodies. The secondary goal is to inspect the endocrine - immune interaction in these persons by detecting the effect of testosterone and oestradiol hormones level on cellular immune response namely, IL - 4, IL - 12. From the first of November 2012 till the end of April 2013, 303 blood samples were collected from apparently healthy male and female students of Al - Erfan, Ignadeen and Algawahery schools and Baghdad University, Both sexes where divided into two age groups : group (A) which included subjects with age range (12 - 15) years old and group (B) which included subjects with age range (16 - 19) years old. All serum samples were tested for toxoplasmosis by using Latex agglutination test and ELISA anti - Toxoplasma IgG antibodies test. As well as, all serum samples were tested by using ELISA technique for detection of serum mean concentration of testosterone, oestradiol hormones, IL - 12 and IL - 4. The results revealed that 107/ 303 (35.31%) of the studied subjects showed seropositive toxoplasmosis, 60 males and 47 females of 107 positive samples showed high significant (p<0.01) differences in comparison to uninfected subjects. Males group B have recorded the highest percentage 34(41.46%) of the infection. Positive association was found between toxoplasmosis and testosterone level in asymptomatic toxoplasmosis cases compared to uninfected group. high mean concentration of testosterone in toxoplasmosis infected males recorded (15.03± 1.04 ng/ml) and (12.4± 0.91 ng/ml) in groups A and B respectively, in comparison to control group which recorded (8.03± 0.78) and (9.86± 0.83) in groups A and B respectively. Also toxoplasmosis infected females revealed high levels of testosterone hormone which represented (4.83± 0.06 ng/ml) and (2.55± 0.03 ng/ml) in groups A and B respectively, with a significant (p?0.05) differences between them, while the control group recorded (0.10± 0.02 ng/ml) and (0.90±0.03 ng/ml) in group A and B respectively.The present study showed a significant (P?0.05) decrease in the mean concentration of oestradiol E2 hormone in toxoplasmosis infected males and females in comparison with uninfected ones. E2 mean concentration was (41± 2.48 ng/ml) and (56± 2.91 ng/ml) for male groups A and B, respectively, in comparison to control group which recorded (67± 2.08 ng/ml) and (74± 2.42 ng/ml) in group A and B respectively, while it was (188 ± 12.48 ng/ml) and (196 ± 16.52 ng/ml) for female group A and B respectively, in comparison to control group which recorded (221±12.09 ng/ml) and (233± 15.63 ng/ml) for group A and B, respectively.The mean concentration of E2 hormone in toxoplasmosis infected females according to their menstrual cycle showed low levels in ovulation, late follicular and luteal phases, which represent (37.5 ± 2.59 ng/ml), (131 ± 16.7 ng/ml) and (76± 3.92 ng/ml) respectively, while the mean concentration of this hormone in uninfected females was (52.4± 2.88 ng/ml), (271.6± 21.04 ng/ml) and (196.2± 12.37 ng/ml) in the three phases of menstrual cycle. This study showed high significant (p?0.05) level of IL - 12 in both males and females with latent toxoplasmosis in comparison with free - toxoplasmosis groups. The mean concentration of IL - 12 in infected males was (4.75 ± 0.88 pg/ml) and (4.12 ± 0.69 pg/ml) in male groups A and B respectively, in comparison to control group which was (2.86± 0.53 pg/ml) and (2.46± 0.62 pg/ml) in groups A and B respectively, while it was (5.60 ± 0.12 pg/ml) and (6.04 ± 0.26 pg/ml) in infected female groups A and B respectively, in comparison to control group which recorded (3.32± 0.89 pg/ml) and (4.27± 0.15 pg/ml) in group A and B respectively. IL - 4 recorded quite elevated level in toxoplasmosis infected males (groups A and B) which was (15.09 ± 0.92 pg/ml) and (17.67 ± 0.78 pg/ml) respectively, in comparison to control group which recorded (13.89± 0.84 pg/ml) and (14.92± 0.69 pg/ml) in groups A and B respectively, Meanwhile the mean concentration of IL - 4 in toxoplasmosis infected females showed mild elevation in both groups A and B which was (15.14 ± 0.84 pg/ml) and (16.06 ± 1.13 pg/ml) respectively, in comparison with toxoplasmosis free subjects which recorded (16.53± 1.22 pg/ml) and (15.15 ± 0.97 pg/ml) with no significant differences between them. Interactions between the endocrine and immune systems may mediate sex differences in response to toxoplasmosis infection.

المستخلص: Studies have linked FOXP3 and TGF - ? expression to the outcome of certain cancers. FOXP3 is a marker known to be expression in T - regulatory cells while TGF - ? is a secreted protein usually detected in the extra cellular matrix.The present study aimed at focusing on the identification of immune markers namely FOXP3 and TGF - ? with their expression patterns in lung cancer patients as a useful tool to predict disease progression.Also it is aimed to design molecular evaluation of m RNA expression of both FOXP3 and TGF - ? in peripheral blood mononuclear cells and bronchial (brush) cells of patients with lung cancer and benign lesions, using qRT PCR; determining the T - reg level in the peripheral blood employing the High Rsolution Melting (HRM) as a novel method to detect Treg - specific demethylated region (TSDR); molecular DNA analysis of somatic mutation of exons 3, 6, 7 of FOXP3 in patients with lung cancer tissue and benign lesions and immunohistochemical (IHC) estimation of FOXP3 and TGF - ?1 in T - reg and cancer cells in formalin fixed paraffin embedded(FFPE)lung cancer tissue and benign lesions.Blood samples were collected from 30 patients with newly diagnosed, non small cell lung carcinoma and 30 patients with benign lesions.Patients were recruited at The Specialized Surgery Hospital and Oncology Teaching Hospital/Baghdad.Samples from 16 apparently healthy donors were used as control during the period from June 2012 to June 2013. The samples preservation with TRIzol reagent were subjected to molecular study including RNA and DNA extraction; reverse transcription; RT - PCR; HRM assay and DNA sequencing were done in the Molecular Oncology Unit/Guys and ST Thomas? s hospital/ King College/London/UK.The expression level of FOXP3 was high in 16(61.5%)in lung cancer cases.A significant difference was noticed between cancer cases from one side and benign lesions or healthy control on the other side p<0.05.Mean of FOXP3 expression(fold change)was significantly high(2.64±0.09)in cancer cases than in benign cases(1.32±0.04)and healthy control(1.38±0.06)with p<0.05.A significant association between high expression level and >60 age and squamous cell carcinoma in cancer cases P<0.05.The expression level of TGF - ? was high in 16(61.5%)in lung cancer cases.A significant difference was noticed between cancer cases from one side and benign lesions or healthy control on the other side p<0.05.Mean of TGF - ? expression (fold change) was significantly high (6.27±0.56) in cancer cases more than healthy control (2.87±0.09) with p<0.05.The association was significant between TGF - ? expression level (high and low) and age>60in cancer and benign groups (p<0.05), while no significant association with gender and cancer types were noticed.For FOXP3 mRNA expression in bronchial brush cells, the result showed no significant difference between the mean fold change of malignant(3.57 ± 0.06) and benign(4.02 ± 0.06) patients. The low expression was predominated both in cancer and benign cases. No significant differences were found between FOXP3 expression (high and low) and age; gender ; cancer types..According to FOXP3 T - reg specific demethylated region detection, results showed that the mean percentage of FOXP3demethylation in lung cancer patients (4.32 ± 0.04) was significantly higher than in benign lesions (3.22 ± 0.02) patients andhealthy controls(3.33±0.04). A positive correlation coefficient with high significant, was found in the group of cancer samples (R² = 0.6653;r = 0.69;P : 0.0017)on correlating percentage of Treg and demethylation of FOXP3 from one side with its m RNA expression on the other side.In benign lesion group was(R² = 0.5334;r= 0.59;p= 0.0027), While in the control group a positive correlation but a weak significance was found (R²= 0.2383;r=0.28;P=0.0437).FOXP3 gene sequencing revealed high frequency of missense mutations c.715 GTA>CTA : V 239 L in 17 (94.44%) in malignant sample and non cancerous cases7 (87.5%)without statistical differences. Missence mutations were also detected in exone 3 in 3(16.67%) cancer cases and in 1(12.5 %) benign lesion.No missense mutations could be detected in exon 6. Intronic mutations and silent mutation were variable in three exons without statistical differences. Many cases of adenocarcinoma have shown multiple mutations either of missense or Intronic types. Missense mutations of exon 7 were correlated significantly with an age of 60?years. Exon 3 mutations were significantly associated with adenocarcinoma. Positive FOXP3 Immunohistochemistry (IHC) staining in tumor cells was associated with high missense mutations frequency 10(55.55%) in exon7, while in exone 3 was 2(11.11%). Negative FOXP3 IHC staining in the tumor cells was associated with seven missense mutations in exon7 and one (5.55%) in exon 3, in addition 4(23.53%) cases of the exon 7 missense mutations were associated with negative FOXP3 expression in lymphocytes.The result showed that FOXP3 by using IHC staining was positive in 21(70%) of nuclei of cancer cells, and 22(73.3%)in Treg infiltrates.The positive cancer cells and Treg infiltrates associated significantly with age>60 (p<0.05).No significant association was found withgender, cancer type, while there is association with moderate differentiation compared to poorly differentiation (p<0.05). High frequence of FOXP3 expression score 3 and high intensity were appeared in nuclear cancer cells compared to benign lesions cells, while Treg infiltrates with score 1 and high intensity was high frequency in malignant and benign.The result showed that TGF - ?1 by using IHC staining was positive in 25(83.3%) in the cancer cells and 21(70%) in stromal cells. No significant difference was noted between positive expression in malignant and benign lesions p>0.05.No significant association was noticed between positive cells expression and age, gender, cancer type and differentiation p>0.05. High frequency of TGF - ?1 expression score 3 and high intensity in malignant cells and benign. Also stromal cell expression score 3 and high intensity were predominated in malignant and benign lesions. The high and moderate intensity expression was more frequent in matrix surrounding cancer cells compared to non cancerous.Total agreement and kappa coefficient between FOXP3 and TGF - ?1were poor in malignant and benign epithelial cells and stroma, while the perfect agreement was between expression of TGF - ?1in stromal cells

المستخلص: The present study aimed to understand the correlation between serum level of nine cytokines (IL - 1?, IL - 1RA, IL - 2, IL - 4, IL - 6, IL - 10, IL - 12, IFN - ? and TNF - ?) and their genetic polymorphisms at 16 gene positions defined by sequence specific primer - polymerase chain reaction (SSP - PCR) in pulmonary tuberculosis (PTB) patients, and in addition HLA - DQB1 gene polymorphism was also defined by SSP - PCR to determine their role in susceptibility or resistance to M. tuberculosis. Finally, serum level of cortisol was also determined in the patients.Ninety four Iraqi Arabs PTB patients (70 males and 24 females) were enrolled in the study. They were referred to the Institute of Chest and Respiratory Diseases in Baghdad for diagnosis and treatment during the period May - October 2012. A control sample of 80 apparently healthy individuals was also included and matched patients for gender (60 males and 20 females) and ethnicity. The results are summarized in the following : 1. A significant increased serum level of IL - 1? (24.16 ± 8.82 vs. 3.20 ± 1.18 pg/ml), IL - 1RA (41.31 ± 6.64 vs. 16.85 ± 5.50 pg/ml), IL - 2 (17.63 ± 3.53 vs. 7.80 ± 1.10 pg/ml), IL - 4 (9.56 ± 2.60 vs. 3.81 ± 1.70 pg/ml), IL - 10 (34.49 ± 4.60 vs. 7.61 ± 1.70 pg/ml), IL - 12 (25.16 ± 5.85 vs. 7.70 ± 1.12 pg/ml) and TNF - ? (22.52 ± 4.41 vs. 4.97 ± 1.15 pg/ml) was recorded in PTB patients compared to controls. Also, Cortisol serum level was significantly increased in patients (215.47 ± 1.33 vs. 38.63 ± 1.74 ng/ml).2. Cytokine gene polymorphism analysis revealed that neither genotypes nor alleles of IL1A - 889, IL2 - 330, IL2+166, IL4 - 590, IL4 - 33, IL6+565, IL10 - 819, IL10 - 592, IL12B - 1188 and TNF - 238 genes showed a significant variation between PTB patients and controls. In contrast, the frequency of TT genotype of IL1RN gene at position mspal 11100 showed a significant (P = 0.004) increase in PTB patients compared to controls (65.9 vs. 43.7%). For IL4 - 1098, the frequency of TT genotype was also significantly (P = 0.048) increased inpatients (82.9 vs. 70.0%). At position - 174 of IL6 gene, a significant (P = 0.002) increased frequency of GG genotype was observed in patients (55.3 vs. 31.2%). For IL10 gene, only GG genotype at position IL10 - 1082 was observed with a significant (P = 0.045) increased frequency in patients (18.1 vs. 7.5%). At position - 308 of TNF gene, a significant (P = 6.9 x 10 - 5) decreased frequency of GG genotype was observed in patients (60.6 vs. 87.5%), while GA genotype was significantly (P = 1.3 x 10 - 4) increased (38.2 vs. 12.5%). Finally, the frequency of AA genotype of IFNG gene at position +874 demonstrated a significant (P = 0.006) increase in PTB patients (55.3%) compared to controls (33.7%).3. To determine the impact of cytokine genotypes on cytokines serum level, PTB patients and controls were distributed according to their serum level in the three genotypes of each cytokine. It was found that CC genotype of IL1RNmspal 11100 in patients was observed with the highest IL - 1RA level (52.16 ± 5.81 pg/ml) compared to TT (41.39 ± 3.23 pg/ml) or TC (38.10 ± 4.54 pg/ml) genotype. The TT genotype of IL2 at position - 330 also showed the highest level of IL - 2 (22.16 ± 4.31 pg/ml) compared to TG (17.59 ± 3.40 pg/ml) or GG (13.68 ± 3.53 pg/ml) genotype in patients. The IL4 - 1098 TT genotype showed the highest level of IL - 4 in patients (10.38 ± 2.21 pg/ml) compared to TG (6.09 ± 1.20 pg/ml) or GG (3.93 ± 0.80 pg/ml) genotype. For IL10 gene, the GG genotype of IL10 - 1082 recorded the highest level of IL - 10 (40.67 ± 2.96 pg/ml), which was significantly different from AA genotype (26.66 ± 5.65 pg/ml). At position - 308 of TNF gene, serum level of TNF - ? in GG genotype of patients demonstrated a significant increased mean compared to genotype GA (24.76 ± 1.30 vs. 19.15 ± 1.12 pg/ml). At position - 238, TNF GG genotype showed a significant increase level of TNF - ? (23.02 ± 2.91 pg/ml) in patients compared to AA genotype (17.18 ± 1.53 pg/ml) of patients. Finally, IFNG+874 AA genotype was observed with the highest IFN - ? level in patients (11.07 ± 1.12 pg/ml) compared to AT (7.97 ± 1.81 pg/ml)or TT (6.10 ± 2.20 pg/ml) genotype. In contrast, no such differences were observed in controls.4. Out of the five encountered HLA - DQB1 alleles, DQB1*03 showed a significant (P = 0.005) increased frequency in PTB patients compared to controls (71.3 vs. 50.0%). It was also observed that heterozygosity at such gene locus was significantly (P = 0.03) more frequent in patients than in controls (93.6 vs. 82.5%), while homozygosity was observed with a less percentage frequency in patients compared to controls (6.4 vs. 17.5%) and the difference was also significant (P = 0.03).Accordingly, it is possible to conclude that the cytokine profile was deviated in PTB patients, and such deviation was correlated with the genotypes of some cytokines, which might also together with HLA - DQB1polymorphism confer the individual an immunogenetic predisposition to develop M. tuberculosis infection.

المستخلص: استهدفت الدراسة الحالية عزل وتشخيص بكتيريا Streptococcus mutans المسؤولة عن تنخر الاسنان البشري والتكلسات (plaque) واستخراج اضداد لها من صفار بيض الدجاج Yolk Immunoglobullin (IgY) لغرض استخدامها مستقبلا كمثبطات لنمو هذه البكتيريا الخطيرة ويمكن مزجها مع مع | The presented study aimed to isolate the main agent for dental caries and teeth plaque, Streptococcus mutans bacteria, and then production of specific antibodies against these harmful bacteria by the use of chicken egg yolk immunoglobulin (IgY). S. mutans had been proposed as the main etiological agents of dental caries and high levels of mutans streptococci in the plaque is correlated with a higher risk for dental caries. Seventy five plaque samples were collected from human teeth. Forty two samples were considered to be positive bacterial isolates using MS - agar (Mitist Salivares agar). Thirty five isolates were considered belonging to the group Streptococci; among these isolates 29 isolates were expected to be belonging to mutans streptococci group according to ability of producing special kind of exopolysaccharides. Ten isolates were considered as S. mutans with a percentage of 41% depending on staining with triphenyltetrazolium chloride and tolerance with NaCl 4%, 6 isolates were classified as serotype C by using Lancefield grouping identification. These isolates were tested for production of extracellular Glucosyltransferase (GTF) through determination of their enzyme specific activity. All isolates were able to produce the enzyme; Streptococci isolate (H5) identified as Streptococcus mutans serotype C was selected as the best producible isolate for GTF with a specific activity of 2.6 U/mg. It was found that GTF of the chosen isolate (H5) was produced during the middle stationary phase (18 - 35 hr.) and its maximal productivity was reached at 22 hr. Purification of S. mutans serotype (C) H5 GTF were done by ammonium sulfate, ion - exchange chromatography (DEAE - Sephacel column), and gel - filtration chromatography using Sepharose 6B column. The best percent saturation use for precipitating GTF by ammonium sulfate was 20 - 40% with specific activity 3.4 U/mg. Two purified GTF enzymes (GTF - I and GTF - II) were detected with specific activity 8.3 U/mg, 35.5 U/mg after 22.6, and 96.1 fold of purification respectively with yield 17.2%. Purification S. mutans CA - GTF (H5) were done by 8M urea, ammonium sulfate, DEAE - Sephacel column and gel - filtration (sepharose 6B) column chromatography. The purified CA - GTF was detected with specific activity 18.1 U/mg after 24.5 fold of purification with yield 20.2%. Determination of purified GTF (GTF - I, GTF - II) and CA - GTF molecular weight was done by using gel - filtration chromatography (sepharose 6B) column with presence of standards proteins. It was found that the molecular weight of GTF - I, GTF - II and CA - GTF was 125.819, 112.201 and 84.139 dalton, respectively. The ability of GTF, CA - GTF and whole cell of S. mutans to stimulate the immune system of avian hens was tested. The intramuscular rout injection of three purified antigens (GTF, CA - GTF and whole cell) in the chest of experimental hens was done. IgG from egg yolk hens (IgY) was purified through the post immunization period (9 weeks) by using polyethylene glycol (PEG) precipitation and protein content of IgY antibodies was estimated from egg yolk and serum. Each one milliliter of purified IgY egg yolk samples GTF, CA - GTF and Whole cell, protein contained 7.06, 6.97, 3.9 mg/ml, respectively while in serum protein content about2.6, 3.1 and 3.25 mg/ml, respectively. The Sodium dodecyle sulfate polyacrylamide gel electrophoresis (SDS - PAGE) of anti - GTF (IgY) indicated that purified IgY gave two bands; 47.863 and 34.673dalton which were considered to be IgY heavy and light chains respectively. the IgY - CA - GTF sample is the best in terms IgY specificity 34.07% while the two samples (GTF, Whole cell) performed 30.5% and 29.3% respectively, Igy - GTF the best in terms purity 49% followed IgY - CA - GTF 47% and IgY - whole cell 46.3%. The immunological specificity of the three IgY samples preparations was assessed by ELISA test and the best sample that produced high titration was IgY - GTF with concentration 3.5 mg/ml, followed by the IgY - CA - GTF and IgY - whole cell with concentration 3.28 and 3.1 mg/ml respectively. The IgY - GTF inhibited approximate 75% of the specific activity GTF, while IgY - CA - GTF inhibited 50% of the specific activity CA - GTF. A double immunodiffusion test for detection of the immune response between anti - GTF IgY and purified GTF, CA - GTF and Whole cell antigens were recorded. The immunological response of anti - GTF and anti - CA - GTF was indicated by the appearance of precipitation lines on the surface gel between anti - GTF and two antigens GTF and CA - GTF while in the anti - CA - GTF and anti whole cell only with homologues antigen. The effect of different concentration of inhibitor (Amoxicillin) and anti - GTF, anti - CA - GTF and anti - whole cell on the growth of S. mutans bacteria were tested using broth dilution method and diffusion method on solid medium. Anti - GTF and anti - CA - GTF had no effect on the growth of S. mutans(H5) serotype C, while anti - whole - cell and Amoxicillin were capable to inhibit the growth of bacteria at concentration 20µg/ml and 15µg/ml respectively. The minimal inhibitory concentrations in which these concentrations were noticed at 35µg/ml and 30 µg/ml respectively. The highest zone of inhibition (40 mm) was recognized with Amoxicillin at concentration of 50 µg/ml, followed by anti - whole cell with a zone of inhibition of 34 mm at concentration of 70 µg/ml.

The total number of the studied groups was 95 Iraqi patients (45 diabetic dental caries patients (DDCP) and 50 non - diabetic dental caries patients (NDCP) of both genders who their ages ranged from 18 - 65 years old. The patients, samples including saliva and buccal swabs that randomly collected from DDCP and NDCP who were reviewing Al - Alweyia Centers of Dental Caries and Diabetic Diseases in Al - Yarmook hospital in Baghdad city. The distribution of patients who have dental caries according to genders showed high significant differences at (p<0.01) between two genders (30 females, 15 males) for diabetic dental caries patients, while in non diabetic dental caries patients, there were significant differences at (p<0.05) between two genders (29 females, 21 males). The distribution of diabetic dental caries patients according to age showed high significant differences at (p<0.01) between two genders in age group of 36 - 50 years old, While low significant differences at (p<0.05) between two genders in age group of 20 - 35 years old and no significant differences between two genders in age group more than 50 years old, In another hand in non diabetic dental caries patients, there were no significant differences between two genders in all age groups. The results of samples (saliva and buccal swabs) culturing on mitis salivarius bacitracin agar media (MSBA) appeared that out of 95 bacterial cultures, 67 bacterial cultures were grown (32 bacterial cultures for diabetic dental caries patients and 35 bacterial cultures for non diabetic dental caries patients); S. mutans, S. salivarius, and S. oralis species were identified according to the results of microscopic examination, API kit 20 - strep, hemolysis on blood agar, motility test and catalase test. The molecular study focused on the analysis of DNA which extracted directly from saliva, buccal swabs and from the bacterial culture cells of S. mutans, S. salivares and S. oralis from both diabetic dental caries patients and non diabetic dental caries patients. Polymerase chain reaction (PCR) results revealed the presence of the product with 433, 544, and 374 bp which were related to gtfD (S. mutans), gtfK (S. salivarius) and gtfR (S. oralis) respectively in all samples (saliva, buccal swabs and bacterial culture). According to the presence of these three genes, there were high significant differences at (p<0.01) between diabetic dental caries patients and non diabetic dental caries patients, while there were no significant differences according to the percentage of presence of each gene between the three species of bacteria. Sequencing of the PCR products of the gtfs (gtfD, gtfK, and gtfR) genes region showed that nine samples gave acceptable results according to National center for Biotechnology Information (NCBI) matching, while 3 samples gave no results; this may be due to an error in sequencing system. The sequencing analysis of gtfs gene (gtfD, gtfK and gtfR) revealed that in DDCP the highest percentage of recorded mutations was in the gtfR gene.While in non diabetic dental caries patients, the highest percentage of recorded mutations in the gtfK gene than gtfR genes. In gtfR gene all mutations were substitution for diabetic dental caries patients and non diabetic dental caries patients. Nevertheless, in diabetic dental caries patients the mutations in gtfK and gtfD genes distributed between substitution and deletion mutations without recording any type of insertion mutation. But, in non diabetic dental caries patients, in gtfD all mutations were distributed between three types of mutations (substitution, insertion and deletion). The highest percentage of the effect of mutations in gtfs genes (gtfD, gtfR and gtfK) in diabetic dental caries patients were silent and missense mutation's than the frameshift mutations. on the other hand, the highest percentage of the effect of mutations in gtfs genes (gtfD, gtfR and gtfK) in non diabetic dental caries patients was missense mutations as compared with the other two types of silent and frameshift mutations

Genomic DNA was isolated by using Geneaid DNA extraction kit from the whole blood; conventional PCR (SNP - 44 and Del/Ins - 19) and PCR - RFLP (SNP - 43 and SNP - 63) were used to detect the calpain10 variants by using specific primers and restriction enzymes. The study population consisted of 50 subjects with type 2 diabetes and 50 with normal fasting blood glucose (80 - 110 mg/dl). The type 2 diabetic subjects were recruited from the National Center for Diabetes treatment and Research. The non - diabetic control subjects were recruited from the same area as the comprising blood donors, healthy volunteers, or hospital /university staff members. Previous studies have detected a role for Calpain - 10 (CAPN10) polymorphisms in susceptibility to Type 2 diabetes mellitus (T2DM) in many populations. This study aimed to evaluate possible associations between these polymorphisms in the CAPN10 gene (SNP - 44, SNP - 43, Del/Ins - 19, and SNP - 63) and T2DM incidence in Iraqi population. Enrichment of allele 1(2R) in Del/Ins - 19 and 2R/2R genotype were found in T2DM patients. While the alleles and genotypes distribution of SNP - 44, SNP - 43 and SNP - 63 were not significantly different between patient groups and non - diabetic control subjects. The genotype AA in SNP - 43 and genotype TT in SNP - 63 were not found neither in T2DM nor in control subjects. of the eight haplotypes detected, enrichment of both haplotype 112 defined by variants of SNP - 43, Del/Ins - 19, and SNP - 63 and haplotype 2112 defined by variants of SNP - 44, SNP - 43, Del/Ins - 19, and SNP - 63 were seen in patients. The distribution of the other haplotypes was comparable between patients and control subjects. The calpain10 haplotype combinations were also obtained, and the haplotype combinations 111/111 and 111/112; which are created by variants of SNP - 43, del/ins - 19 and SNP - 63 and; haplotype combinations 1111/2111, 1111/2112 and 1121 / 2222; created by SNP - 44, SNP - 43, del/ins - 19 and SNP - 63; were associated with increasing the risk of T2DM.

المستخلص: Markers have been described in type 1 diabetes mellitus (T1DM), There is a number of specific and non specific antigens have been identified. The major autoantigens involved in the destructive process of beta - cells leading to the development of type 1 diabetes are insulin hormone, glutamic acid decarboxylase (GAD), tyrosine phosphatase enzyme or Insulinoma - associated Antigen - 2(IA - 2).This study was conducted to find the relationship between antibodies for this antigens (insulin, GAD and IA - 2) and T1DM which could be used for the early detection of T1DM in normal Iraqi population. To study the importance of anti - thyroid peroxidase (anti - TPO) as a marker for autoimmune thyroid disease (ATD) in T1DM patients, and to find the relationship between T1DM and ATD.The study was carried out on 50 blood samples of men and 30 blood samples of women with age ranged from (20 - 60 years old), they were divided in to three groups : 1. Group 1 (20 men and 10 women) whom have fasting plasma glucose (FPG) above 180 mg/dL.2. Group 2 (20 men and 10 women) whom have FPG ranged from 120 - 180 mg/dL.3. Group 3 (10 men and 10 women) whom have FPG below 120 mg/dL.Blood samples were collected from all subjects, FPG and glycated haemoglobin (HbA1c) were measured. The levels of insulin, anti - insulin, anti - GAD, anti - IA - 2 and anti - TPO antibodies were measured in the serum.The statistical analysis results showed no significant difference in the presence of antibodies, HbA1c and FPG between men and women groups, inspite of some simple differences between the two groups.A significant (p<0.05) elevation in the level of FPG and HbA1c was observed in diabetic patients group compared withnon diabetic group. Significant (p<0.05) decrease in the level of insulin of T1DM patients was noticed compared to non diabetic group. Significant (p<0.05) elevation in the level of (anti - insulin, anti - TPO) in T1DM patients compared with non diabetic group. Elevation in the level of (anti - GAD, anti - IA - 2) in the T1DM patients compared with non diabetic group.The results also showed that no positive results for (anti - insulin, anti - TPO) present in the non diabetic group. One positive result for anti - GAD and one positive result for anti - IA - 2 present in the non diabetic group, which indicate the importance of anti - GAD and anti - IA - 2 antibodies ssay in normal population that could be used as early detection of T1DM.

Lippia nodiflora (L.) Rich.29. Tribulus terrestris L.Some of these species have been anatomically investigated for the first time.Anatomical characters might be useful for plant biologist for the identification of important wild plants as an additional character at global level. Comparative anatomical characters were used; such as characteristics of ordinary epidermal cells of stems and leaves and stomatal complexes. The epidermis possesses number of important diagnostic character that offer valuable clues for identification, like size, shape, in addition to indumentum of both stems and leaves. Venation system was investigated and compared. Cross sections of root were useful taxonomically especially the thickness of epidermis, cortex, phloem and xylem. The study observed presence of sclerenchyma tissues in the root cortex of some species. Cross sectioning of stems and petioles were also studied. Epidermis, cortex, pericycle, vascular bundle shapes and numbers, pith characters, presence of crystals and tannin filled cells were useful aid in distinguishing species. Vertical sections of leaf blades, shape and number of vascular bundles, thickness of palisade and spongy layers and other mesophyll characters were important taxonomically.ccording to some of these characters, species were divided into groups. This study concluded the presence of variations in characters and these were presented for the first time comparatively, so that, the anatomical characters were a good support to the exomorphological characters in the studied species. Field photographs of the different studied plants and sections of organs were put in addition to numerous tables in this work. The above results were discussed scientifically regarding mainly the environmental factors.

المستخلص: تضمنت الدراسة الحالية عزل وتشخيص طحالب كبيرة من بيئتين مائيتين محليتين مختلفتين. تم عزل ثلاث طحالب كبيرة هي Cladophora glomerata (N) وEnteromorpha rafsii من منطقه بحر النجف في محافظة النجف, في حين عزل Cladophora glomerata (R) من احد مبازل منطقة الراشدية ش | The present study includes isolation and identification of Macro - algae from two different environmental water bodies. Three Macro - algae were isolated, Cladophora glomerata (N) and Enteromorpha ralfsii from Baher Al - Najaf region in Holy Najaf city. In addition, C. glomerata (R) was isolated from Al - Rashdiya, north of Baghdad.Phytopathogenic fungi from soil and some infected fruits were also isolated. They were identified as Pythium ultimum and Rhizoctonia solani.Water and ethanol were used to extract each algae to evaluate their antifungal activity against isolated phytopathogenic fungi. Different concentrations of these algal extracts had been prepared which are (10, 25 and 50) mg/ml and the antagonistic activity against the isolated phytopathogenic fungi were evaluated, the hot and cold water extracts did not show any antagonistic activity against fungi. However, all these extracts were ignored in the future work for this study. Furthermore, the hot ethanolic extract was more efficient than these of cold ethanolic extracts. Results have been shown that there were significant differences when macro - algal ethanolic extract were used.C. glomerata (R), which isolated from Al - Rashdiya, was more efficient against tested fungi than the same alga what isolated from Baher Al - Najaf region. However, E. ralfsii extract was more efficient against tested fungi than C. glomerata (N). Percentage of inhibition against P. ultimum when hot ethanolic extract of E. ralfsii, C. glomerata(R) and C. glomerata(N) were (88.8, 83.3 and 63.3) respectively.However, results for cold ethanolic extract of the same algae were (63.3, 52.2 and 32.2) respectively when 50 mg/ml of algal extracts were used.Percentage of inhibition against R. solani when hot ethanolic extract of E. ralfsii, C.glomerata (R) and C.glomerata(N) were (94.4, 100 and 78.8) respectively.However, results for cold ethanolic extract of the same algae were (66.6, 64.4 and 48.8) respectively when 50 mg/ml was used. According to the difference in biological activities against those phytopathogenic fungi caused by the same species of macro - algae or different genera from different environments. Due to difference in biological activity of the same macro - algae species Physiochemical parameter for each environments obtained such as air and water temperature, Turbidity (NTU), Electrical Conductivity(EC)and Salinity%, Water pH, CA+2 concentration, Mg+2 concentration, Total Hardness and Total Alkalinity. Results indicated that soaked Cucumis sativus and Capsicum annum seeds in cold and hot ethanolic macro - algae extracts of (E. ralfsii, C. glomerata (R) and C.glomerata (N) for 24 hours were able to protect seed germination that have been grown in a Petri dish contaminated with P. ultimum and R. solani comparing with control. In addition, results indicated that spraying C. sativus and C. annum seedling with these algal extracts within two weeks old again protects these seedlings from the same phytopathogenic fungi either before or after 24 hr. However, results indicated that adding the algal extracts within two months age to the C. sativus and C. annum plants again protects these plants from the same phytopathogenic fungi comparing with control and fungicide treatment. Moreover, results indicated that the active chemical compounds in E. ralfsii was Tannins, Saponins and Flavonoids. While C. glomerata was contained Tannins, Saponins, Alkaloid and Phenols. Results indicated that both hot crud methanolic extract of C. glomerata (R) and E. ralfsii have a lot of active chemical compounds against micro - organisms by using the GC - Mass Spectrometry technology.

المستخلص: In order to detection of Pseudomonas aeruginosa in food - chain especially from Cows raw milk and soft cheese with its whey, this study was designed in some regions of Baghdad (College of Veterinary Medicine, Abu - Ghraib, Al - Sadrya & Al - Radwaniyah), in which a standard isolation methods were used with some modification processing by new, modern and rapid technology tools such as chromogenic medium CNP agar and Electronic rapid Microbact TM 24E panel identification system supported by standard color differential chart and online American Type Culture Collection (ATCC) Codes; aids in rapid and precise identification, differentiation, confirmation and enumeration of P. aeruginosa isolates from raw dairy samples; as well as, detection of biofilm producing versatile morphotypes with chameleon phenomenon and fruity odour; and demonstration the activity of food spoilage enzymes (protease, lipase & lecithinase) of isolates with thermo - stability and viability in different temperatures with bitty cream and ropy fermentation phenomenon. The results profile showed : 1. Isolation of 46 (76.7%) isolate of P. aeruginosa from a total of 60 Cow Dairy samples : 30 Raw Milk samples (pooled from milk cans and apparently healthy Cows with a history of mastitis cases) as 19 (31.7%) isolates from regions of College of Veterinary Medicine, Abu - Ghraib and Al - Sadrya (10 from each region); and 30 Soft Cheese with its Whey samples (pooled from unhygienic processed cheese and containers in unclean dirty environment and apparently carrier or diseased workers) as 27 (45%) isolates from regions of Abu - Ghraib, Al - Sadrya and Al - Radwaniyah (10 from each region). Isolation percentages of oxidase positive P. aeruginosa from selected Regions in Baghdad Province indicates significant differences among regions at a level (P?0.05), in which highest isolation percent of P. aeruginosa from Abu - Ghraib as 20 (33.4%) isolates (10 isolates from raw milk and 10 isolates from soft cheese) in accordance to 17 (28.4%) isolates from Al - Sadrya (9 isolates from raw milk and 8 isolates from soft cheese), 9 (15%)SUMMARYisolates from Al - Radwaniyah (9 isolates from soft cheese) without any isolate from College of Veterinary Medicine, which may indicate good hygienic measurements.2. Segregation of isolates into two Haemolytic Patterns : Livestock type origin, lysis only sheep blood (L - type) as 19 (41.30%) isolates from raw milk samples; and Zoonotic type lysis, both blood (Z - type) as 27 (58.70%) isolates from soft cheese with its whey as high prevalence due to critical processing chain, risky carrier individuals and contaminated environment or polluted water supply. This may indicate indirectly genetic diversity and host or cross individual tropism in haemolysins - phospholipases activity according to different types of samples, regions and hosts.3. The study revealed isolation and segregation of versatile morphotypes and five pigments with fruity odor (Chameleon phenomenon) with mucoid drippy due to alginate or small colonial variants smooth or rough or both especially in isolate code M7 from mastitic milk and isolate code C27 from contaminated soft cheese and its whey. Wrinkled - Corroded green morphotypes were more evident in blood agar due to secretion of siderophore pyoverdine in order to chelating iron for activation of isolate. Motility Pattern with TTC salts was evident in all isolates with three types of motility : swarming, swimming and twitching, that noticed obviously in M7 isolate.4. New technology biochemical identification panel system (Microbact TM 24E) confirm that isolates were P. aeruginosa at level (P?0.01) after online matching with standard Remel ATCC Octalcodes bank of P. aeruginosa, in which 5 octalcodes typical and atypical were documented, that indicate genetic diversity in biochemical reactions of isolates and their morphotypes, modified microbial gene sharing protocol of P. aeruginosa with other bacteria and highly Sensitivity and Specificity of the test panel.SUMMARY5. Detection and isolation of Biofilm producing isolates by five methods, in which microtiter plate assay was the most sensitive and realizable technique while Congo red agar test detect quantity and type of biofilm production through colour of colonies (black very strong and huge, gray strong, pink moderate and white fair or non - producer). Biofilm produced in most morphotypes with pellicles at liquid interphase and ropy viscous threads (sliminess) and bitty cream especially in isolate codes M7 and C27. Small colonial variants of some morphotypes can revert to mucoid drippy variants. M7 showed unusual ropy thread of 30 cm long.6. The results showed secretion of thermo and psychro stable and labile food spoilage enzymes (protease, lipase and lecithinase) from isolates, in which versatile morphotypes showed indirectly diverse genetic ability, this may indicate variation of thermal tolerance mechanisms (heat shock proteins and biofilms formation) in isolates in accordance to time and temperature of processing, that linked genetically with the quorum sense mechanisms of acyl homoserine lactone gene regulatory region (AHL) in P. aeruginosa isolates (Stress Hardening phenomenon).7. The results showed the genetic ability (indirectly) of some isolates to resist, tolerate and proliferate in acidic environment at pH 2 & 4 especially isolate M7 & C27, while intermediate to susceptible tolerance of pH were noticed in others. This may indicate the power of electromagnetic charged net field of complex polymeric matrix of alginate exopolysaccharide layers in protecting some isolates from adverse acidic environment due to quorum sensing behavior of M7 & C27.Therefore, it could be concluded from this study that P. aeruginosa was prevalent in food chain especially from Cows raw milk and soft cheese with its whey samples from some regions in Baghdad, and Biofilm producing isolates with their thermo and psychro stable enzymes complex system and their tolerance to acidic environment stressors were more dangerous thus, we recommend monitoring these products periodically for insurance of public health.

المستخلص: This in vitro study was conducted to evaluate and compare the efficiency of XP - endo Finisher, EndoActivator sonic irrigation system and the NSK Varios ultrasonic irrigation system in removing dentin debris at three levels of root canals and to compare the percentage of dentin debris among the three levels for each irrigation system. Sixty freshly extracted upper molar teeth with straight palatal root canals were used in this study. All canals were prepared with ProTaper NEXT rotary files to size X4, 1mm from the anatomic apex with irrigation of 1 ml 2.0% NaOCl between the files. After that the samples were randomly distributed into three groups of twenty samples each, irrigated with 1 ml 2.0% NaOCl, followed by irrigant activation for 60 seconds with three different irrigation systems; group one, by using the XP - endo Finisher; group two, by sonic irrigation using the EndoActivator system; and group three, by ultrasonic irrigation using the NSK Varios, then all the groups received a final rinse of 5 ml 2.0% NaOCl. After the final rinse, the roots were split longitudinally into two parts and photographed with a professional digital camera. The digital images were then transferred into a computer and opened in Adobe Photoshop CC 2015 software and the canal was magnified 200x. The percentage of dentin debris remaining at the apical level (0 - 3mm), the middle level (3 - 6mm) and the coronal level (6 - 9mm) was calculated by dividing the number of pixels occupied by the dentin debris at each level by the number of pixels representing the entire canal area. Data were analyzed statistically by ANOVA and LSD at 1% and 5% significant levels. This study showed that cleaning the canal with the XP - endo Finisher or NSK Varios ultrasonic irrigation system resulted in significantly cleaner canals (P<0.01) than the EndoActivator sonic activation system at all canal levels. The XP - endo Finisher resulted in cleaner canals than the NSK Varios ultrasonic irrigation system at all levels, but the difference is not statistically significant (P>0.05). The apical level of all the canals showed a greater amount of dentin debris (P<0.01) compared to the middle and coronal levels, regardless of the irrigation device used.

المستخلص: t is important to analyze and compare the stresses induced in different composite material types during load application to know which type of composite will behave as preferred under the loading in the same circumstances. This study aimed at measuring and comparing the stress induced in Filtek ™ Z350 XT (3M ESPE) composite, Tetric EvoCeram ® (ivoclar vivadent) composite and BRILLIANT ™ NG (Coltène/Whaledent) composite experimentally and numerically.Experimental analysis included cavity preparation in the Brass block with a concave (U - shape) cavity which represent a proximal cavity preparation. This cavity was used as a mold for sample preparation. The internal line and point angles of the cavity (mold) were rounded and the dimensions of the cavity (mold) were 10mm × 10mm × 10mm (Total height of the box × Width of the top side of box × Length of the top side of box). The internal diameter of “U” was 5 mm at the base of the box. The mold was used to prepare forty five samples, fifteen samples for each type of composite material. So, three groups were prepared : Group A filled with Filtek ™ Z350 XT composite material, Group B filled with Tetric EvoCeram ® composite material and Group C filled with BRILLIANT ™ NG composite material.Electrical strain gauge (Tokyo Sokki, Japan) was embedded in composite material horizontally at the same level in each sample. Static load of 50 N was applied perpendicular to the center of the occlusal surface of composite restoration in each sample testing. The strain gauge was connected to a Wheatstone bridge with a signal amplifier which measures the strain during load application and gives the amplified signal from (0 to 4.8 volt) to LabJack data acquisition where a stream software give the final values of strain with the aid of a scaled equation of voltage. Then, the von Mises stress (effective stress) was calculated by using equations. Numerical analysis was done by using ANSYS 16.1 - (2015) (finite element tool) software that was used to create the 3 - Dimensional models represented the same materials and dimensions used experimentally. The physical characteristics of the composite models were inserted in the software which included Elastic modulus and Poisson’s ratio (?). Analysis was selected in a finite element method according to boundary conditions. A mesh size and an element size were estimated during the study. The stresses were calculated at static load of 50 N with the ANSYS 16.1 - (2015) software.The data were analyzed statistically by One - way ANOVA test and Least Significant Difference (LSD) test. One - way ANOVA test and LSD test results showed that there was a highly significant difference (P<0.001) presented between groups A and B, groups A and C and between groups B and group C. The Stress induced in BRILLIANT ™ NG composite after load application was the lowest stress value followed by Tetric EvoCeram ® composite and followed by Filtek ™ Z350 XT composite which was the highest stress value experimentally and numerically.

المستخلص: Although investigators have evaluated the microleakage of porcelain laminate veneers, there is insufficient data regarding the durability of porcelain laminate veneers bonded to existing composite fillings. The aim of this study was to evaluate the microleakage of porcelain veneers restorations fabricated from two types of CAD/CAM ceramic blocks bonded to teeth with or without composite class V composite filling.Forty eight sound, crack - free human maxillary first premolar extracted for orthodontic reasons were selected for this study. Teeth were divided randomly into.2 main groups, which further divded into 2 groups (12 sample each). Group A1 : IPS e.max CAD veneers with standardized class V composite filling, Group A2 : IPS e.max CAD veneers, Group B1 : VITA Suprinity veneers with standardized class V composite filling, Group B2 VITA Suprinity veneers. The class V cavities was restored with nanofilled composite (Filtek™ Z350 XT, 3M ESPE). Standard veneer preparations were made using Ceramic veneer burs system (Keramikveneers. de, Komet). All the veneers were milled by CAD/CAM technology (CEREC MC XL, inLab SW 15, Sirona Dental Systems) Composite fillings (groups A1 and B1) were sandblasted with alumina oxide.Porcelain veneers were cemented in place using light - cured resin cement (Rely Veneer Cement, 3M ESPE), Then the specimens were stored at 37? in distilled water for 2 weeks. Then mechanical load cycling (50,000 load cycle of 49 N at 2.5 Hz) and thermocycling procedure (500 cycles of 5 - 55 Co with 20 sec dwell time) were done. The specimens’ crowns were immersed in 2% methylene blue dye for two days, then mounted in clear acrylic before sectioning with a 0.35 mm microtome. Microleakage percentage were recorded using stereomicroscope and ImageJ program. Results were checked for normality of distribution (Kolmogorov - Smirnov test and Shapiro - Wilk test), and were analyzed with twoway ANOVA and independent samples t - tests. Two way ANOVA shows the significant effect of type of ceramic restoration and the highly significant effect of composite filling, however, the interaction between the main factors was non - significant. The results showed that the lowest mean of microleakage percentage was recorded for group A2 (4.6058% ± 1.5091) which considered statistically significant compared to group B2 (6.105%±1.456), and statistically highly significant compared to group A1 (6.6075%±1.3259) while group B1 recorded the highest mean of microleakage percentage (7.3158%±1.38713). In conclusion, the type of ceramic restoration and the presence of class V filling both had significant effects on microleakage of porcelain veneers. IPS e.max CAD veneers had significantly lower microleakage percentages compared to VITA Suprinity veneers. The presence of class V composite filling within the cervical finishing line of porcelain veneers had a highly significant higher microleakage percentage compared to groups without composite filling.

Vertical root fracture is one of the most frustrating complications of root canal treatment, which often results in tooth extraction. The aim of this in vitro study was to compare the effect of different Nickel Titanium instruments (ProTaper Universal, EndoSequence, ProTaper Next and RECIPROC) on the dentinal wall in term of dentinal defects.Seventy - five straight palatal roots of freshly extracted human maxillary first molars teeth were used in this study, the palatal roots were sectioned at 11 mm from the apex and wrapped with two layers of aluminum foil, then placed in the center of elastic silicon mold. Fifteen roots were left unprepared to serve as a negative control group, the remaining 60 roots were divided into 4 groups, each group contained 15 roots : • Group I was prepared by rotary ProTaper Universal system.• Group II was prepared by rotary EndoSequence system.• Group III was prepared by rotary ProTaper Next system.• Group IV was prepared by reciprocating RECIPROC system.All canals were prepared to MAF # 40. After each file size of the (rotary files) or after three pecking motion of the (reciprocating files), the file was removed from the canal and the canal was irrigated with 1 ml of 2% of sodium hypochlorite. All files were cleaned periodically to prevent clogging of flutes during instrumentation. The canal remained patent by insertion size 15 K - file.When the instrumentation was completed, the roots were then embedded in a clear acrylic resin blocks and each root was sectioned into three levels : apical, middle and coronal. All samples were examined from coronal direction under Stereomicroscope. The number and the type of dentinal defects were recorded and classified. The collected data was tabulated and subjected to statistical analysis using chi - square test.The EndoSequence group showed the lowest number of dentinal defects followed by ProTaper Next group and then ProTaper Universal group. The highest number of dentinal defects were observed in RECIPROC group. Chi - square test showed that there were highly significant differences among groups (P < 0.01). The results showed a non - significant difference between EndoSequence and Protaper Next group (p > 0.05), and a significant difference with ProTaper Universal group (P < 0.05) and a highly significant difference with RECIPROC group (P < 0.01). The ProTaper Next group showed a significant difference with ProTaper Universal group and a highly significant difference with RECIPROC groups. There was no significant difference between RECIPROC and ProTaper Universal groups.

المستخلص: الربو القصبي المزمن يمثل مشكله صحيه جديه في كل العالم وهو عادة يبدا في عمر الطفوله ويبقى المريض في كثير من الاحيان يتعاطى العلاجات المستنشقه مدى الحياة.انتشار الربو القصبي يزداد في كثير من دول العالم مما يجعله احد الامراض المعيقه والمهدده للحياة باعتبا | Asthma is a serious global health problem that usually starts in childhood and continues along patient’s life and most of them have to take inhaled therapy lifelong. The prevalence of asthma is rising in many countries of the world, making asthma one of the most disabling and life threatening diseases effecting patients with different age groups and social classes with variable clinical spectrums and outcomes starting from mild to severe disabling syndrome rendering nonproductive individuals to severe life threatening and sometimes fatal disease. Those patients continue inhaled steroid therapy for long duration, considered by GINA as first line treatment , however such a treatment is associated with local adverse effects on oral tissues, and one of the main concerns is the development of oral candidiasis, a chronic, potentially invasive, infection of oral tissues with fungus candida species resulting in failure of treatment. The scientific interests about such a serious complication have been raised over the past years and debates continued as the candida is considered one of the normal flora of the oral cavity in most of healthy population, however oral candidiasis in pathogenic forms still occur in immunocompromised patients including asthmatics on inhaled corticosteroid therapy.Aim of the study1. To investigate the effect of inhaled corticosteroid therapy in form of Beclomethasone Dipropionate250 microgram/dose CFC free in asthmatic patients on salivary candidal shed estimating by Real Time quantitative Polymerase Chain Reaction (RT qPCR) applied on direct unstimulated saliva samples.2. Evaluation of this shed as prediction of occurrence of oral candidiasis. Patients, Materials and MethodsThis study was conducted at Al Zahraa consultational Asthma and Allergy center - Baghdad Al Karkh Health Directorate from September 2013 to February 2014.The included patients were divided into 3 groups. Group A included asthmatic patients on inhaled Beclomethasone therapy, group B included asthmatic patients that never used any form of inhaled steroid therapy and group C was those asthmatic patients on inhaled Beclomethasone therapy who developed oral candidiasis. All patients were receiving two daily doses. The same exclusion forma was applied to choose Group D who were control healthy individuals. Each included patients and control cases were instructed to give saliva samples in the standard way and samples taken for estimation of candidal count by real time quantitative Polymerase Chain Reaction.Results During the study period, 698 patients were examined, however only 63 patients were included in the study. Those 63 were classified as follows : 28 patients were found on group, 28 were found on group B and only 7 patients were found on group C and 20 cases were selected in group D as a control.Group C patients were having the highest salivary candidal shed (mean=58.7x106 cn/ml) and longest duration of asthma (Mean=2718 days) and longest duration of Beclomethasone therapy (Mean=2224 days) and this was significantly higher than other groups (p<0.05).Group A patients were having the second highest rank after group C in regard of salivary candidal shed and both duration of asthma and Beclomethasone therapy. Inside each group, duration of asthma and duration of Beclomethasone therapy were associated with moderate positive correlation with salivary candidal shed (R>0.5).Age difference between groups were insignificant and age factor had no correlation with salivary candidal shed inside the groups.Discussion : Salivary candidal shed over the groups was directly related to the duration of inhaled Beclomethasone therapy and duration of asthma. They are significantly higher (p<0.01) as we go further from each group to the next, both appear as the reason behind increased candidal shed in groups A and C.The salivary candidal shed curve will gave us a very useful tool for follow up those patients on inhaled steroid therapy ,In addition , predict the risk of developing oral candidiasis and when to interfere prior to the establishment of Oral Candidiasis state as that we have noticed in the group C, in which it was recommended to stop inhaled steroid therapy and the patients would lose the benefits of the therapy.Conclusions1. Resting saliva samples with realtime quantitative PCR was a rapid and accurate tool in diagnosis of oral candidiasis.2. Salivary Candidal Shed could be used as a tool in predicting oral candidiasis in asthmatic patients on inhaled Beclomethasone therapy.3.Longer duration of asthma and longer duration of Beclomethasone therapy were associated with increased salivary candidal shed and established oral candidiasis have the highest amount of shed.4. Candida albicans are present in the oral cavity of any individual of our population

المستخلص: Resin composites have improved greatly since their introduction and are now the materials of choice for most of the restorations. This study was conducted with aim of comparing in vitro the marginal adaptation of three different, low shrink, direct posterior composites Sonic fill™ (nanohybrid composite), Filtek™ P90 (Silorane - based composite) and Filtek™ Z350 (nanofill composite) of a standardized Class V cavity after thermoal cycling. Sixty sound, freshly extracted human premolars were prepared with standardized Class V cavities. The specimens were divided into three groups of twenty teeth each according to the material used : Group A : The teeth were restored with Sonic fill™ posterior composite unidose capsules, Group B : The teeth were restored with a silorane - based posterior composite (FiltekTM P90), Group C : The teeth were restored with nanofill methacrylate - based composite (Filtek™ Z350 XT).After specimens were stored in distilled water at 37°C for 7 days, all specimens were subjected to thermocycling at (5° to 55 °C), then immersed in 2% methylene blue dye for 24 hours. For each group microleakage at the occlusal and gingival regions was estimated by determining dye penetration using scoring system under steromicroscope (10X). The statistical analysis of the results showed that, Filtek™ P90 silorane based composite exhibited the lowest mean of microleakage, with statistically highly significant difference (P < 0.01) when compared with Sonicfill™ composite and Filtek™ Z350 XT nanofill composite. On the other hand, the results of this study showed that Sonic fill™ composite exhibited no significant difference (P > 0.05) as compared with Filtek™ Z350 XT nanofill composite. Also, the results in this study showed that there is a highly significant difference (P < 0.01) in dye penetration between occlusal and gingival regions for each group

المستخلص: اضطرابات المفصل الفكي الصدغي تشير الى مصطلح مركب يحتوي على عدة حالات تتضمن المفصل الصدغي,التركيبات المحيطة او كلاهما.اضطرابات المفصل الفكي الصدغي هي مجموعة اعراض معقدة اكثر من كونها حالة معينة واحدة, ويعتقد انها تنتج من عدة عوامل مثل : العوامل الجينية, ال | Tempromandibular disorders is a collective term, embracing several clinical problems involving the muscles of mastication, temporomandibular joint (TMJ), or both.Tempromandibular disorders is a symptom complex rather than a single condition, and it is thought to be caused by multiple factors like : genetic, developmental and metabolic.TMDs form a cluster of related disorders with common symptoms which include localized pain, limited or asymmetric movement, and clicks or grating on opening.Psoriatic arthritis is a chronic inflammatory arthropathy that affects patients with psoriasis. Psoriatic arthritis is most commonly a seronegative oligoarthritis found in patients with psoriasis and therefore occurs more commonly in patients with tissue type HLA - B27. The clinical findings for Tempromandibular Psoriatic arthritis are pain, tenderness, limitation of movement , joint stiffness, clicking as the jaw is opened or closed, difficulty in opening the mouth, locking of the jaw,and crepitations. These findings are essentially the same as for Tempromandibular disorders.• Objective of the study : • To determine the extent of tempromandibular joint involvement in patients with psoriatic arthritis.• To correlate between clinical findings and radiographic finding.Materials and method : In this study 98 patients were selected ,50 male and 48 female, their age ranged between(18 - 68)years. They were collected at Al - yarmook teaching hospital/department of dermatology during the period from ( NOV 2014 - May 2015).They were diagnosed as having psoriatic arthritis by a dermatologist according to (Moll and Wright diagnostic criteria 1973).These patients were sent to rheumatoid factor test RF to exclude the presence of rheumatoid arthritic disease, then the patients were exposed to CT scanning for the Tempromandibular joint in Al - Yarmook teaching hospital for screening the involvement of TMJ with psoriatic arthritis by the presence of any radiographic changes such as erosion, flattening,osteophyte and sclerosis in the condylar head.Results : The result of the study showed that the mean age of psoriatic arthritic patients in TMJ was (44.2) years, and the female percentage was (48.4%) and the male was (51.6%). Psoriatic arthritis in TMJ showed high significance in the unilateral side symptoms (100%) it was significant in patients with positive family history (54.8%), and non significant in the right/left ratio (41.9%). Oligo type was found in twenty six patients (83.9%) with significant p - value. Clinically, all symptoms including clicking, tenderness and tempromadibular joint pain were highly significant, limitation showed (54.8%), TMJ pain showed (64.5%) and tenderness showed (54.8%).Radiologically : CT scan showed sensitivity for erosion in TMJ (54.8%), for osteophyte (32.3%), for condylar flattening (16.1%) and for sclerosis (9.7%) while specificity for all were (100%). Association between clinical symptoms and radiological changes showed non significant correlation. Conclusions : Psoriatic arthritis of TMJ has been found oftenly unilateral (oligo type). Female/ male ratio is about 1 : 1. nearly 50% of patients were having limitation in mouth opening. Most of the patients were having positive family history.The development of psoriatic arthritis in TMJ is related to the duration of the disease. Plaque psoriasis is the most associated type with the psoriatic arthritis in TMJ. Most of patients with psoriatic arthritis show psoriatic nail changes. The most radiographic findings found in patients with psoritic arthritis was erosion in the condylar head. There is association between clinical and radiologic findings for psoriatic arthritis in TMJ.

This study was performed to compare the marginal fit changes and facture resistance of metal ceramic crowns constructed from Ceramill Sintron metal coping veneered with three different porcelain veneering materials (Vita Master Koromikos VMK, Willi Geller Creation CC and GC initial MC). Also evaluating the influence of thermocycling on load at fracture value. The method included the use of master brass die which was milled to represent the prepared maxillary central incisor. Sixty metal copings were milled directly using Ceramill Sintron blank, then divided randomly into three groups. Each group consist of twenty metal copings, then veneered with porcelain : VITA for group A, Creation for group B and GC for group C. The marginal gap was measured before and after porcelain veneering for each group using travelling light microscope, then marginal fit changes was calculated. Fracture resistance test was done by Instron®, the master die was duplicated to sixty analogs then each analog was fixed into acrylic base. After that each crown was cemented onto the corresponding die analog using zinc phosphate cement. Ten samples of each group were subjected to compressive loading to fracture and other ten subjected to thermocycling followed by compressive loading to fracture.The result showed that GC group was highly significant different from other tested groups in marginal fit changes, whereas there was no significant different between VITA and Creation group. While there was significant difference among tested group at (P < 0.01) in fracture resistance, and the effect of thermocycling process did not significantly reduce the load at fracture for all groups.This study concluded that GC group present the least marginal fit changes, while the fracture resistance was highest for VITA group follow by Creation then GC. Thermocycling reduce load at fracture but not significantly.

المستخلص: تحضير قناة الجذر يشمل كلا من تشكيل وتوسيع المساحة اللبية بالاضافة الى تطهيرها من الجراثيم، من دون اي خطا اجرائي هو من اقصى درجات التفضيل. حديثا، في مجال تطبيقات حشوات الجذور، ادوات النيكل تيتانيوم اصبحت تستخدم بصورة شائعة لتنظيف وتشكيل قناة الجذر. ادوات ا | Root canal preparation includes both shaping and enlargement of the endodontic space in conjunction with its disinfection, without any procedural error is of the utmost preference. Recently, in endodontic practice, the nickel - titanium instruments are used commonly for the preparation of the root canal space. Nickel - titanium instruments are much more flexible than stainless steel files and have superior cutting efficiency. Super - elasticity of nickel - titanium rotary instruments allows the clinicians to produce the desirable tapered root canal form with a reduced tendency to canal transportation and instrument fracture. The target of this study was to measure and compare the canal transportation and centering ability of iRaCe and ProTaper NEXT nickel titanium instruments with ProTaper Universal instruments in simulated curved canals at different levels and compare canal transportation and centering ability among different levels for each tested instrument.Sixty simulated curved canals of 40°curvature were randomly divided into three groups of twenty canals each; the first group (group A) was prepared with iRaCe instruments, the second group (group B) was prepared with ProTaper NEXT instruments and the third group (group C) was prepared with ProTaper Universal instruments. The canals were prepared to an apical size 30 by crown - down instrumentation technique. Removal of material was measured at five different levels : at the canal orifice (O), half way to the orifice in the straight sections (HO); the beginning of the curve (BC); the crest of the curve (AC); the end point (EP). Pre - and post - operative photos of the simulated canals were taken in a standardized technique at magnification of 40X. An assessment of canals shape has been determined using Photoshop CC 2014 and AutoCAD 2014 software program. The data of canal transportation as well as centering ratio were analyzed statistically using Shapiro - Wilk, ANOVA and LSD tests.Within the limitation of this study, it is shown that canals preparation with the three designs of NiTi instruments produced canal transportation. However, the iRaCe instruments showed a significantly less canal transportation and a significantly better centering ability than both ProTaper NEXT and ProTaper Universal instruments at all levels of measurements, followed by ProTaper NEXT instruments that showed a significantly less canal transportation and significantly better centering ability at all levels when compared with ProTaper Universal, while the ProTaper Universal instruments showed the highest values of canal transportation and the worst ability to stay centered in the canals at all levels. Considering the direction of canal transportation, the iRaCe instruments showed minimal transportation towards inner aspect of canal at coronal and at the apex of curve and towards outer aspect of canal at middle, beginning of curve and at the end point of the preparation, while ProTaper NEXT instruments were showed transportation usually towards the inner aspect of the canal at middle part of the canal and towards the outer aspect at coronal, beginning of curve, apex of curve and at the endpoint of the preparation, while ProTaper Universal files were usually towards the inner aspect at middle part of the canal and towards the outer aspect at coronal, beginning of curve, apex of curve and at the endpoint of the preparation.

The etiopathology of the temporomandibular joints is related to muscles, teeth arches, and periodontium. Their main causes involve both pathophysiological and psychosocial factors. In the literature, a significant impact of the psychoemotional factor is reported, comparable to the impact of other factors concerning physical health such as systemic diseases, malocclusions, loss of teeth, and traumas. Stress, fatigue, anxiety, depression, sleep disorders, and a fast pace of life affect negatively the human psyche.Aim of study : The aim of the study was to assess the prevalence of temporomandibular disorders (TMD) and oral parafunctions, as well as their correlation with psychoemotional factors among dental students by using diagnostic criteria (DC/TMD).Subjects, materials and methods : the sample’s size of 407 students (169 males and 238 females) of dental college (100 fifth stage , 102 fourth stage ,99 third stage and 106 second stage ). Firstly students subjected for stress questionnaire (perceived stress scale - 10) , secondly they subjected to different clinical and questionnaire measures according to diagnostic criteria of temporomandibular disorders DC/TMD (axis1) which have standerized series of diagnostic tests based on clinical signs and symptoms , finally the dental students subjected for oral parafunctions questionnaire using oral behavior checklist.Results : the results obtained from this study showed that the prevalence of TMDs was significantly greater among students with oral parafunctions. We also observed that the prevalence of TMDs according to DC/TMD was higher among students with headache.In this study, the prevalence of psycho - emotional stress , TMD according to DC/TMD and oral parafunctions were higher in females than males and in fifth stage greater than other stages.Conclusion : • the prevalence of TMDs according to DC/TMD were significantly higher among females than males.• Oral parafunctions ( bruxism , cheek/lips biting , objects biting and nail biting ) showed greater prevalence in fifth stages than others and higher in females than males • In all stages females showed greater prevalence of psycho - emotional stress than males and among students of fifth stage the prevalence of psycho - emotional stress was higher than other stages.

All teeth had mature apices, selected carefully according to specific criteria. The roots were instrumented using crown down technique with rotary Protaper universal system, instrumentation were done with 5ml of 2.5% sodium hypochlorite used as irrigation between files, 17% buffered solution of EDTA was used as final irrigant followed by 2.5% sodium hypochlorite then 10ml distilled water to remove any remnant of irrigant. Roots were randomly divided into three groups according to the filling materials used ( twenty roots for each group) : Group (1) : MTA Plus ( 4mm thickness) using as apical third filling. Group (2) : Biodentine (4mm thickness) using as apical third filling.Group (3) : Bioceramic root repair material (4mm thickness) using as apical third filling.Easy and Quick (E&Q) obturation system were used to complete obturation of roots. After incubation period at 37 °C for three days. Ten roots from each group were used for push - out test, after root were embedded in clear acrylic resin, sectioned at apical level in 2mm and 4mm from root apex to provide slice 2mm in thickness. The bond strength was measured using computerized universal testing machine, each section fixed in the machine so that the load applied from apical to coronal direction at 0.5mm/min speed and the computer drew curve to show the higher bond force before dislodgment of the filling material. These force were divided by surface area to obtain the bond strength in MPa.After debonding each sample was examined under Stereomicroscope and the type of failure mode was recorded. The result showed non significant different between Biodentine group and MTA Plus group. Biodentine group showed a very high significant difference with Bioceramic material group. Also high significant difference between MTA Plus group and Bioceramic material group. The Biodentine group showed highest mean of bond strength in comparison to other test group.Ten roots remain from each group used for apical microleakage study. The roots submerged in 2% methylene blue for three days. The roots were cleared and the degree of linear dye penetration was measured in millimeter by stereomicroscope under 40 X magnification with calibrated scale ocular grid. The result showed the Biodentine group lowest mean of microleakage than other group while Bioceramic material group showed high mean of microleakage than other groups. There are no significant difference among groups. There is positive correlation between push - out bond strength and an apical dye penetration in microleakage for each group of material.

المستخلص: Esthetic dentistry as a concept and adhesive materials development as a functional element make the new dawn of dentistry especially with the continuous development of adhesive techniques. This study is to evaluate the failure patterns of porcelain laminate veneers used to esthetically restore maxillary first premolar by bonding them to enamel and dentin with two different techniques.Forty eight extracted human maxillary first premolar were used for this study. Teeth were divided randomly into one control group and three experimental groups of twelve teeth eachGroup (A) were prepared in enamel (0.5 mm) depth of preparation. Group (B) were prepared in dentin (1 mm) depth of preparation and their veneers were bonded by DDS technique. Group (C) were prepared in dentin (1 mm) depth of preparation and their veneers were bonded by IDS technique. Standard preparation for each tooth in the experimental groups with ceramic veneer set burs especially designed for laminate veneer preparation. All the experimental groups were restored with the same type of veneer which was lithium disilicate ceramic CAD/CAM blocks (IPS e. max CAD, ivoclar vivadent) and were milled by CAD/CAM technology (CEREC inLab 4.02 milling system, Sirona).For all the experimental groups, Choice™2 veneer cement (Bisco, USA) was used for the luting of veneers. After cementation, teeth were stored in distilled water in 37°C for one week. The specimens were loaded to failure using instron universal testing machine. Specimens in experimental groups were examined by stereomicroscope at magnification of 20x to evaluate the mode of failure.Results were statistically analyzed and showed that the highest mean of failure load was recorded for the control group (548.1 N ± 93.2), for group (A) the mean of failure load was (393.4 N ± 84.2), and for Group (B) had the mean of failureAbstract IIIload was (237.8 N ± 91.6), and for group (C) the mean of failure load was (318 N ± 82.2).The one way ANOVA test was carried out and showed that there is a statistically high significant difference among the groups.Then the LSD test have shown that there is a statistically high significant difference between the control group and all three of the experimental groups, and there was a statistical high significant difference between group (A) and group (B), while group (C) have shown that there is a statistical significant difference with groups (A) and (B).The mode of failure varied from only debonding in groups (B and C) to deboning and fracture in group A.In conclusion, this study found that although enamel is still the most favorable tooth substrate for indirect adhesive restorations, the development of bonding techniques like IDS made dentin as acceptable tooth substrate for indirect adhesive restorations when it's unavoidable.

المستخلص: Background : Parkinson's disease (PD) is a progressive neurodegenerative disorder related to the loss or absence of dopaminergic neurons in the brain. The deficits caused by PD result in slowness of movement, tremor, rigidity, and dysfunction of behavior and these symptoms negatively influence the patient’s capability to carry out the daily oral hygiene manoeuvres.Aims of study : This study aims at using saliva as a biological fluid for assessment in detecting the biomarkers of Parkinson's disease and to assess the impact of this disease on the oral health of patients.Materials and methods : A total number of fourty participants were involved in the study; twenty subjects who appeared healthy (Group I) and twenty Parkinson's patients (Group II). Patients who are eligible for this study were cases of Parkinson's disease treated with anti - Parkinson's medications, both genders and their ages ranged from 40 - 75 years. Specific information related to the demographic characteristics and illness is obtained from each patient. The Brain Bank Diagnostic Criteria for Parkinson’s disease established by United Kingdom Parkinson's Disease Society was used. Each patient was subjected to oral examination during which DMF index was scored, oral health impact Profile OHIP - 14 was used and from each participant the whole unstimulated saliva was collected for biochemical analysis including total salivary protein, direct determination of saliva proteins and determination of ? - synuclein. Results : many oral and clinical signs and symptoms elsewhere in the body were reported in the patient with Parkinson's disease while the clinical features of Parkinson's disease observed in all patients despite of their treatment. Static tremor observed in 100%, rigidity in 70%, disturbances in the autonomic nervous system reflected on the cardiovascular, gastrointestinal and urinary tracts, orthostatic dizziness observed in 75%, dry mouth in 65% difficulties in swallowing in 40% and constipation in 70%. Teeth examination revealed that Parkinson's patients have a non - significant high means of decay and missing teeth compared with healthy subjects. The total saliva protein in Parkinson's patients is significantly higher than the corresponding value of healthy subjects. The extinction coefficient of uncontaminated protein in Parkinson's patients is significantly less than the corresponding values of healthy subjects and salivary ? - synuclein level is significantly less in Parkinson's patients than healthy subjects.Conclusions : Salivary ? - synuclein may serves as a biomarker for Parkinson's disease. Specific protein with extinction coefficient 27.5 M.Cm - 1 is secreted in saliva of Parkinson's patients. The characteristic saliva protein produced in patients with Parkinson's disease is deficient in tyrosine level and Dental care is required for both groups (Parkinson's patients and healthy subjects).

The commonest manifestations are muccocutaneous but can involve eye, cardiovascular and neurological systems. There are many modalities of therapy topical and systemic.Isotretinion has been tried as an effective therapy of muccocutaneous manifestations. In present work was to try a new retinoid like acitretin which has longer half life than isotretinoin.Aims of the study : To evaluate the effectiveness of oral acitretin versus oral zinc gluconate in the treatment and prophylaxis of Behcet’s disease as a new therapeutic model.Materials and methods : This cross over controlled therapeutic study that conducted in the Department of Dermatology - Baghdad Teaching Hospital the period from August 2013 - May 2014.Twenty patients with fulfilled criteria of Behcets’s disease was included in this work. History and full examination were done for all patients regarding all demo - garaphic points related to the disease. They were given acitretin 25 mg orally once daily for three months to be seen on the day fourteenth firstly and then monthly to be assessed depending on the clinical manifestation index for Behcets disease. After three months, acitretin was stopped and patients were given zinc gluconate 25 mg twice daily for another three months. Results : Twenty patients were treated 12 males (60%), and 8 females (40%), with male to female ratio 1.5 : 1. All these patients completed the study and their ages ranged between 20 - 59 years with mean± SD (37.3±12.3). Pathergy both ordinary and oral were also minimized by this therapy while C - reactive protein was not much effective by this therapy. Zinc gluconate also had the same therapeutic action against these manifestations. Clinical manifestations index before treatment ranged between 1 and 11 with mean ± SD of 5.65±1.98.After acitretin therapy the mean of CMI started to decline to reach 2.65 ±2.03 in first month of the therapy with (p=0.00001) which was statistically high significant and continued high significant till the end of the third month with (p - value > 0.000001). After cessation of acitretin and zinc gluconate started the mean continued to decrease to reach 2.05±2.52 at the end of the first month with (p=<0.000001) which was statistically high significant then; started to increase to reach 3.3 ±2.31 at the end of six month of the therapy but statistically remained high significant (p - value=0.0007). Both acitretin and zinc gluconate have statistically significant effect in reducing severity and frequency of oral ulcers, genital ulcers, skin and rheumatologic manifestations. Conclusions : oral acitretin was found to be an effective therapy in addition to its prophylactic action in treatment of muccocutaneous manifestations of Behcet,s disease. Also zinc gluconate had effective therapeutic action against these features of Behcet’s disease.

المستخلص: الحمل هو حالة فسيولوجية تجلب مجموعة واسعة من التغييرات في حياة المراة، بما في ذلك التعرض لامراض اللثة، ربما بسبب التغيرات الهرمونية المرتبطة مع الحمل. قد تؤثر الهرمونات الجنسية على اغشية الفم واللثة وربما هذا يؤدي الى العديد من الامراض اللثوية. ان هرمونا | Pregnancy is a physiological state that brings a wide range of changes in a woman’s life, including a susceptibility to gingival disease, probably due to hormonal changes associated with pregnancy. These female sex hormones may modify the oral mucosa and may lead to various degrees of gingival inflammation. The hormonal changes occurring during pregnancy may be associated with pregnancy gingivitis and gingival bleeding. Sex hormones are specific regulatory molecules have long been considered to play an influential role on periodontal tissues especially gingiva, bone turnover rate, wound healing and periodontal disease progression. Aims of the study1. Assessment of oral hygiene level and dental status in both second and third trimester pregnant women and compares results.2. Assessment salivary hormonal levels of endogenous female sex steroids in both second and third trimester pregnant women and compares results.3. Comparison of oral health status and endogenous female sex steroids salivary hormonal levels between gingivitis and non - gingivitis subgroups of both second and third trimester pregnant women groups.4. Find out the association between the gingival health status and salivary hormonal levels of endogenous female sex steroids (Estradiol and progesterone).Materials and methods This study was carried out on seventy - eight pregnant women who were attended for routine and regular follow up visits in obstetrics and gynecology department at Al - Yarmouk Teaching Hospital, from February 2013 to July 2013. This study was approved by the scientific committee in the department of oral medicine college of dentistry Al - Mustansiriya University. They were divided according to gestational age in to second trimester group and third trimester group. Fifty pregnant women (age range 18 - 38 years) and at gestational age was ranged between (20 - 27 weeks) were recruited as 2nd trimester group and Twenty - eight pregnant women (age range 18 - 39 years) at gestational age ranged between (28 - 33 weeks) were recruited as 3rd trimester group and according to Loe and Silness gingival index these two groups subdivided into gingivitis and non - gingivitis groups. Oral clinical examination including an assessment of gingival inflammation (Loe and Silness Gingival Index), Plaque amount (Silness and Loe Plaque Index), dental status (Decayed Missing Filling Teeth), and salivary flow rate (SFR) had also been done. Samples of whole unstimulated (resting) saliva were collected from all participants then investigated for sex steroids salivary hormonal levels of Estradiol, Progesterone. Results and discussion Oral health measurements including : GI, PLI, SFR and DMFT showed no significant difference between 2nd trimester and 3rd trimester groups. Sex steroids salivary hormonal levels of Progesterone showed a significant difference with higher mean value in 3rd trimester pregnant women than 2nd trimester pregnant women while sex steroids salivary hormonal levels of Estradiol showed no significant difference between two groups. Comparisons between gingivitis and non - gingivitis subgroups of 2nd trimester pregnant women group showed that there was highly significant difference in SFR with higher mean value in non - gingivitis group, and there was highly significant difference in PLI with higher mean value in gingivitis group, DMFT showed non - significant difference between the subgroups and (Estradiol and progesterone) salivary hormonal levels showed highly significant difference with higher mean values in gingivitis group. Comparisons between gingivitis and non - gingivitis subgroups of 3rd trimester pregnant women group showed that there was a non - significant difference in SFR, DMFT and a highly significant difference in PLI with higher mean value in gingivitis group, while progesterone salivary hormonal levels showed non - significant difference and Estradiol salivary hormonal levels showed a highly significant difference with higher mean value in gingivitis group. Comparison of GI between gingivitis groups of both 2nd and 3rd trimester pregnant women showed that there was a significant difference with higher mean value in 3rd trimester. Estradiol and progesterone salivary hormonal levels were non - significantly correlated with PLI and GI for gingivitis and non - gingivitis group of 2nd trimester pregnant women. Progesterone salivary hormonal level was non - significantly correlated with PLI and GI for gingivitis and non - gingivitis group of 3rd trimester pregnant women while Estradiol salivary hormonal level was non - significantly correlated with PLI and GI for non - gingivitis group and significantly correlated with PLI and GI for gingivitis group. GI and PLI for gingivitis groups of both 2nd and 3rd trimester revealed that there was a highly significant correlation.Conclusions Female Sex steroids hormones (Estradiol and Progesterone) salivary hormonal levels significantly increase from the second to the third trimester especially Estradiol and Play an important role in influencing gingival inflammation during pregnancy. These hormones are neither necessary nor sufficient to produce gingival changes by themselves. However, they may alter periodontal tissue responses to microbial plaque and thus indirectly contribute to gingivitis. Dental status in pregnant women is not significantly different between 2nd and 3rd trimester pregnant women groups. Women should be offered training in good oral hygiene habits, and community awareness programs should be conducted to increase their awareness of the crucial importance of such habits especially during pregnancy

المستخلص: خلفية البحث : اضطرابات المفصل الفكي الصدغي تشير الى مصطلح مركب يحتوي على عدة حالات تتضمن المفصل الصدغي ,التركيبات المحيطة او كلاهما , تظهر على شكل الم في منطقة المفصل والعضلات المرتبطة,وتحدد بالقدرة على الحركة الطبيعية مثل المضغ, الكلام والبلع. مرض التهاب | Tempromandibular joint disorders is a collective term embracing a number of conditions affecting the TMJ, the surrounding structures or both,manifested by pain in the area of joint and associated muscles, and limitation in the ability to make normal movement like mastication,speech and swallowing. Osteoarthritis is a group of mechanical abnormalities involving degradation of joints, including articular cartilage and subchondral bone. Symptoms may include joint pain, tenderness, stiffness, locking, and sometimes an effusion. A variety of causes—hereditary, developmental, metabolic, and mechanical deficits may initiate processes leading to loss of cartilage. When bone surfaces become less well protected by cartilage, bone may be exposed and damaged. As a result of decreased movement secondary to pain, regional muscles may undergo atrophy, and ligaments may become more lax.Objective of the study : • To determine the extent of tempromandibular joint involvement in patients with osteoarthritis.• To evaluate the correlation between clinical and radiographical findings. • To evaluate the accuracy of sonography in detection of osteoarthritic changes compared to Computed tomography.Materials and method : A comparative study had been done using thirty six symptomatic patients(24 female and 12 male) above 40 years diagnosed as osteoarthritis by specialist rheumatologist in Alkarkh general hospital, with clinical finding related to osteoarthritis like pain,tenderness,crepitation, clicking and limited mouth opening. these patients were exposed to computed tomography(CT) scan (Philips - Brilliance 64) in Al - Karkh general hospital and then the results were compared with sonographic findings (Philips 12.5 MHz transducer) to see the disc displacement, effusion, erosion, flattening, osteolytic and osteophytic lesions in the condylar head.The period of the study started from (october - 2013 to june - 2014).Results : The result of the study showed that the mean age of osteoarthritic patients was (49.69) years, and female percentage (66.7%) and male(33.3%). Chief complaine showed more predilection in the left side (28%) and bilateral showed(56%).Clinically : limitation in mouth opening (50%),crepitation(36.11%), clicking (27.7%), and tenderness (20.8%). Radiographically Computed tomography(CT) scan showed disc displacement (50%), joint effusion (37.5%), flattening(36.11%), osteophyte(18,05%), and erosion(11.1%). There was significant correlation between clicking and joint effusion in computed tomography(CT),while tenderness showed significant correlation with osteophyte and joint effusion in sonography. Other correlations were non significant correlation between clinical and radiological changes. Association between computed tomography(CT) and sonography showed fair agreement in osteophyte detection,fair agreement in joint effusion,moderate agreement in detection of joint erosion,moderate agreement in reduction of space and anterior disc displacement and also moderate agreement in condylar head flattening. Conclusions : Osteoarthritis in tempromandibular joint may be unilateral or bilateral. About 50% of Patients with osteoarthritis have limitation in mouth opening. Clinical findings play a major role in diagnosis of osteoarthritis. The tempromandibular joint changes in osteoarthritis were the results of degenerative processes, in contrast to rheumatoid arthritis were the changes as a result of the disease. Sonography was more likely to be sensitive rather than specific in detection of osteoarthritic changes

المستخلص: Postoperative pain after endodontic procedures is an undesirable occurrence for both patients and clinicians. Certain factors may predispose to the development of postoperative pain. Knowledge of the causes and mechanisms behind interappointment pain in endodontics is of utmost importance for the clinician to properly prevent or manage this undesirable condition. The causative factors of interappointment pain encompass mechanical, chemical, and microbial injuries to the pulp or periradicular tissues, which are induced or exacerbated during root canal treatment. Ninety patients were recruited and included in this study out of one hundred and twenty patients, those patients requiring endodontic treatment on their permanent upper or lower molar teeth with asymptomatic irreversible pulpitis preoperatively, access opening and instrumentation was performed at the same visit.Patients ranged in age from 19 to 50 years old, and all were in good health, as determined from a written health history and oral interview.The patients were assigned randomly into three groups of 30 patients each : ? First group (n=30) : Teeth were instrumented using Universal ProTaper System (Full Rotary technique).? Second group (n=30) : Teeth were instrumented using ProTaper Next System (Full Rotary technique).? Third group (n=30) : Teeth were instrumented using WaveOne System (Reciprocating technique).Pain assessment carried out at day 1, 2, 3 & 7 using Verbal Rating Scale (4 - Point Scale). Patients recorded the incidence and severity of pain experienced.Patients were called at 24, 48 and 72 hours to obtain their reports for the first three days. Seven days after treatment their records were reviewed and percussion test was performed. Result showed that all groups induced Post - operative Pain, the difference is some systems cause more Post - Operative pain than other do : group 3 (WaveOne group) showed higher incidence and severity of PostoperativePain, followed by group 1 (Universal ProTaper group) that has shown less incidence and severity of Post - operative Pain than group 3 (WaveOne group), last group which it was group 2 (ProTaper Next group) has shown the lowest incidence and severity of Post - operative Pain. The data obtained were analyzed statistically using Chi Square test, total score for Verbal Rating Scale at day 1, 2, 3, and 7 showed that there was a highly significant differences between ProTaper Next group and other twogroups (P ? 0.001), and non - significant differences between ProTaper group and WaveOne group (P ? 0.05).

It can be prepared as a drink, which can have many systemic health effects or an “extract” which can be made from the leaves to be used as medicine. Green tea is reported to contain thousands of bioactive ingredients including catechins, catechins found in the tea have shown promise for having antimicrobial effects.Aim of study : to test the effect of green tea extracts on Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans in comparison to 0.2% chlorohexidine gluconate and distilled water in vitro.Materials and Methods : plaque samples were collected from 20 patients with no signs of any systemic disease suffering from chronic periodontitis with probing pocket depth of at least 6 mm, Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans were isolated and diagnosed according to morphological characteristic and biochemical test. Green tea leaves were extracted by using water and alcohol. This study involved two experiments in vitro concerning the effects of green tea extracts on these bacteria in addition to analysis of the extracts to determine the concentrations of the catechins in each extract. The first experiments involved testing the sensitivity of A.a and P.g to different concentrations of the extracts in addition to chlorhexidine gluconate 0.2% and distilled water using agar well diffusion method, the second experiment involved determination of the minimum inhibitory concentration of the extracts that inhibits the bacterial growth and then determination of the minimum bactericidal concentration of the extract that was requires to kill the bacteria. The present study also involved laboratory analysis of green tea extracts using high performance liquid chromatography (HPLC).Results : Both green tea extracts were effective in inhibition of Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans using agar well diffusion method, 90% and 100% concentrations of alcoholic extract showed larger inhibition zones than chlorhexidine gluconate 0.2% with statistically significant difference, CHX showed higher inhibition zones than all aqueous extract concentrations.The MIC (minimum inhibitory concentration) of alcoholic green tea extract that inhibit Aggregatibacter actinomycetemcomitans growth was 60% and it was the same for Porphyromonous gingivalis.The MIC of aqueous green tea extract that inhibits Aggregatibacter actinomycetemcomitans growth was 70% and MIC of aqueous green tea extract extract that inhibits Porphyromonous gingivalis was 80%.The MBC (minimum bactericidal concentration) of alcoholic green tea extract that kills Aggregatibacter actinomycetemcomitans was 80%, the MBC of alcoholic green tea extract that kills Porphyromonous gingivalis was 90%, the MBC of aqueous green tea extract that kills Aggregatibacter actinomycetemcomitans growth was 90%, which was also the same for Porphyromonous gingivalis.HPLC analysis of aqueous and alcoholic green tea extracts that were used in this study revealed that alcoholic extract contained higher concentration of EGCG while aqueous extract had higher content of catechin and epicatechin.Conclusion : green tea extracts were effective against Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans, alcoholic green tea extract showed inhibition ability more than the aqueous green tea extract and more than chlorhexidine gluconate and it showed bactericidal activity at 80%, 90% and 100% concentrations.

المستخلص: Orthodontic mini - implants are increasingly used in orthodontics and the bone density is a very important factor in stabilization and success of mini - implant.The aim of this study was to observe the relationship among maximum bite force; body mass index; face width, height; masseter muscle length, width and thickness; and bone density in an attempt to predict bone density from these variables to eliminate the need for CT scan which have a hazard on patient.Computed tomographic images were obtained for 70 patients (24 males and 46 females) with age range 18 - 30 years. The cortical and cancellous bone density was measured between maxillary and mandibular 2nd premolar and 1st molar at two levels from the alveolar crest (3 and 6 mm). Face height and width and masseter muscle length, width and thickness were measured from CT. Clinically; Maximum bite force was measured on first molar region unilaterally by a digital device. The sample was divided into two groups according to the body mass index into; normal and overweight.The results that were obtained showed that there were no significant differences in bone density or maximum bite force in both genders. Only the cortical bone density in maxilla in overweight group tended to be higher than normal body mass index group. The face width and height correlated significantly negatively with or maximum bite force which correlated significantly positively with cortical bone density and masseter muscle width.It was concluded that a prediction of cortical bone density of preselected areas can be made from maximum bite force, body mass index and inter - zygomatic width

المستخلص: Dental implant surface technologies have been evolving rapidly to enhance a more rapid bone formation on their surface and hold a potential to increase the predictability of expedited implant therapy.Numerous surface modification approaches have been developed for all classes of dental implants to modulate biological responses and improve the osseointegration and primary stability. Hence, Implant threads should be designed to maximize the delivery of optimal favorable stresses while minimizing the amount of extreme adverse stresses to the bone implant interface. In addition, using of biomaterial coating of implant surface for the enhancement of bone formation has been achieved through the modulation of osteoblasts adhesion and spreading that induced better stability and more implant surface contact area.The aims of the study are : 1. Evaluation of titanium implant osseointegration by the modification of thread design and I or coating its surface by Flaxseed.2. Evaluate the new surface modification of titanium implant, histologically, mechanically and radiographically.Materials and methods : One hundred and twenty eight commercially pure titanium (CpTi) screws were implanted in rabbit tibiae. Implants were divided as follows : 1. Dual - threaded group (32 implants). 2. Single - threaded coated with grinded flaxseed group (32 implants).3. Single - threaded with central groove (32 implants).4. Single - threaded (control) group (32 implants).Histological, mechanical and radiographical analysis were performed for all implants after each healing periods (2,4,6 and 8) weeks.Results : 1. Dual - threaded implant illustrated the highest mean value in thread width and removal torque, and it showed mature bone at 8 weeks.2. Grooved implant illustrated close opposing threads. 3. Coated implant illustrated highest mean value in osteoblast cell count and showed a proliferating cartilage zone that later on degenerated and replaced by bone.Conclusion : The present results conclude that each modified implants shows a different benefits whether a modification of the implant surface mechanically (dual or grooved thread) or by coating the implants with Flaxseed.

المستخلص: Fibrous Dysplasia & Ossifying Fibroma of the jawsare maxillofacial fibroosseous lesions sharing anoverlapping clinicopathological characteristics. This can be diagnostically challenging for pathologists& surgeons. It is important to make the distinction because of differences in their clinical behavior, modes of treatment and prognosis.Osteocalcin is an immunohistochemicalmarker; secreted by osteoblasts and its high serum levelsare correlated with increased bone mineraldensity. It is therefore, used as biomarker for boneformation process and also has a role in regulationof osteoblast function.Transforming growth factor beta - 1 is a multifunctional regulator of cell growth which will either stimulate or inhibit proliferation of mesenchymal cells depending on the presence of other growth factors. It is secreted by osteoblasts and is very abundant in bone matrix. Bone morphogenetic protein - 7is a member of transforming growth factor - b superfamily; it is widely expressed during embryonic growth, and is an essential morphogen in renal, skeletal, and eye development.Aims of the study : This study aimedto evaluate and compare the Immunohistochemical expression ofosteocalcin, transforming growth factor beta - 1 andbone morphogenetic protein - 7in the pathogenesis of Fibrous dysplasia and Ossifying fibroma of the jaw bones,correlate the expression of the aforementioned markers in these lesions.Analyze theimmunohistochemical expression ofosteocalcin, Transforming growth factor beta - 1 & bone morphogenetic protein - 7 inFibrous dysplasia & Ossifying fibroma, in order to assess its potential role in differentiation between these two disease entities.Materials&Methods : A total of 30 retrospective formalin - fixed, paraffin - embedded tissue blocks were included in this study, 15 were diagnosed asFibrous dysplasia of the jaws and 15 were ofOssifying fibroma of the jaws. Animmunohistochemicalstaining method using ofosteocalcin,transforming growthfactor beta - 1 andbone morphogenetic protein - 7 monoclonal antibodies were performed.Results : The results revealed that the majority of cases (73.33%) were females for each Fibrous dysplasia &Ossifying fibroma. the age range was (8 - 35)years for Fibrous dysplasia and (7 - 50)years forOssifying fibroma. For Fibrous dysplasia most cases presented in maxilla (66.76%) while for Ossifying fibroma most of the cases presented in mandible (73.33), with more predominant Fibrous dysplasia cases in molar area (60%) and more presented Ossifying fibroma cases in premolar & molar area (33.33%). Statistically significant difference was found between Fibrous dysplasia&Ossifying fibroma cases regarding jaws & site distribution (P=0.02&0.04) respectively.Osteocalcin positive immunohistochemicalexpression was found in fibroblast - like cells in 4 cases(26.66%) of Fibrous dysplasia and in 7 cases (46.67%) of Ossifying fibroma, according to Chi - square test the result showed statistically significant difference regarding osteocalcin expression in Fibrous dysplasia &Ossifying fibroma (P=0.04). Transforming growth factor beta - 1 was positivelyexpressed in 8cases (53.3%) of Fibrous dysplasiaand 10 cases (66.67%) of Ossifying fibroma. Bone morphogenetic protein - 7showed positive expression in 2 cases (13.3%) of Fibrous dysplasia and 4 cases (26.7%) ofossifying fibroma.Statistically non - significant difference regarding the immunohistochemicalexpression of transforming growth factor beta - 1 and bone morphogenetic protein - 7in Fibrous dysplasia &Ossifying fibroma. Moreover significant correlation was found regardingtransforming growth factor beta - 1 expression in response to bone morphogenetic protein - 7in Fibrous dysplasia (P=0.03)and osteocalcin expression in response totransforming growth factor beta - 1 in Ossifying fibroma (P=0.01).Conclusions : Transforming growth factor beta - 1 expressin the majority of Fibrous dysplasia &Ossifying fibroma cases indicate its important role in the process of osteogenesis. The significant correlation seen regarding the expression of some of the studied markers with each other suggest their cooperative role in the pathogenesis of Fibrous dysplasia &Ossifying fibroma

المستخلص: Chronic kidney disease refers to an irreversible deterioration in renal function which classically develops over a period of years, the ageing of populations along with the growing prevalence of chronic diseases such as diabetes and hypertension is leading to worldwide increase in the number of chronic kidney disease patients, the patients suffering from chronic renal failure face oral health related problems because it affects the bone and soft tissue structures.During hemodialysis, blood contact with a foreign surface, such as a complement - activating dialytic membrane, promotes a variety of complex and interrelated events, leading to an acute inflammatory response.Cytokines are a broad and loose category of small proteins that are important in cell signaling, they are released by cells and affect the behavior of other cells, they are important in health and disease, specifically in host responses to infection, immune responses, inflammation, trauma, sepsis, cancer and reproduction.Aims of study : The aims of this study was to determine the prevalence of oral findings, salivary flow rate and evaluation of salivary immunoglobulin A, interleukin - 1? and tumor necrosis factor ? levels in chronic kidney disease patients on hemodialysis treatment in comparison with healthy control, and investigate if there is a relation between these salivary parameters (salivary flow rate, salivary immunoglobulin A, interleukin - 1? and tumor necrosis factor ? levels) in chronic kidney disease patients on hemodialysis (less and more than one year) and finally find the correlation between salivary parameters in patients group.Methods : Ninety (90) subjects were participated in this study, they were divided into two groups : Patients group comprised of 45 subjects undergoing hemodialysis with chronic kidney diseases; Control group comprised of 45 subjects with no history of any systemic diseases.Intra oral examination was done for each individual to record the prevalence of oral findings in chronic kidney diseases patients. Saliva collected was measured and levels of salivary immunoglobulin A, interleukin - 1? and tumor necrosis factor ? were measured by enzyme linked immunosorbent assay (Elisa).Results : The most frequent oral findings in chronic kidney disease patients on hemodialysis, in this study were dry mouth (77.7%), uremic breath (bad odor) (55.5%) , taste alteration (55.5%), angular chelitis (35.5%), mucosal pallor (26.6%), burning mouth syndrome (28.8%), staining of teeth (26.6%), oral ulceration (11.1%) and petechia and ecchymosis (2.2%), and the present study showed that no statistically significant differences (p>0.05) were found in oral findings distribution except angular chelitis which showed statistically significant difference (p<0.05) between chronic kidney diseases patients on hemodialysis for less than one year & for more than one year. According to salivary flow rate, the present study found that there was a significant difference in patients with chronic kidney disease in comparison to healthy control subjects, also statistically there was no significant difference in salivary parameters (salivary immunoglobulin A, interleukin - 1? and tumor necrosis factor ? and salivary flow rate) in chronic kidney diseases patients on hemodialysis for less than one year & for more than one year. The present study showed that there was no correlation between salivary parameters (salivary immunoglobulin A, interleukin - 1? and tumor necrosis factor ? and salivary flow rate) except salivary immunoglobulin A and interleukin - 1? showed positive significant linear correlation (r=0.368, p=0.006) and negative significant linear correlation between salivary immunoglobulin A and salivary flow rate (r= - 0.275, p=0.009).Conclusions : Cytokines may play roles in pathogenesis of chronic kidney diseases represented by increasing interleukin - 1? and tumor necrosis factor ? levels in saliva of those patients, the chronic kidney diseases patients on hemodialysis recommended comprehensive professional oral care and self - care instructions

المستخلص: Worldwide, obesity trends are causing serious public health concerns and significantly increases the risk of morbidity and mortality. It has an effect on the person`s general health including the oral health. Aims of the study : This study was designed to investigate the oral health status among a group of obese boys in relation to salivary inflammatory biomarkers (interleukin - 6 and Creactive protein) and selected salivary elements.Materials and methods : The study group consists of forty obese boy of an age 12 year, and forty normal weighted boy of the same age as a control group. Assessment of nutritional status was done by using Body Mass Index specific for age and gender. Dental caries severity was recorded by using the index of Muhlemann (1976). Plaque index of Silness and Loe (1964) was used for plaque assessment, calculus component of periodontal disease index of Ramfjord (1959) was used for calculus assessment and gingival condition assessed according to gingival index of Loe and Silness (1963). Unstimulated salivary samples were collected under standardized condition, salivary flow rate was determined and then the salivary samples chemically analyzed to determine the concentration of salivary interleukine - 6, Creactive protein, calcium, magnesium and phosphorus.Results : Caries experience of permanent dentition (DMFS) among study group was lower than that among control group with significant difference (P<0.05) for D2, while caries experience of primary dentition (dmfs) was significantly (P<0.05) lower among study group compared with control group with significant difference (P<0.05) for ds and highly significant difference (P<0.01) for d4.Salivary flow rate was lower among study group compared with control group with no significant difference. No significant correlations (P>0.05) were recorded between salivary flow rate and dental caries, oral cleanliness and gingivalhealth conditions among both groups. The mean value of plaque, calculus and gingival indices were not significantly lower among study group compared with control group. A positive highly significant correlations (P<0.01) were recorded between gingival and plaqueindices among both groups. The level of salivary interleukin - 6 (pg/ml) was higher among study group compared with control group with no significant difference between them; whereas there was no significant difference between the two groups regarding C - reactive protein (?g/ml) level. Salivary calcium and magnesium levels (mg/dl) were highly significantly (P<0.01) lower among study group compared with control group, whereas salivary phosphorus level (mg/dl) was not significantly higher among study group compared with control group. Salivary interleukin - 6 and C - reactive protein were negatively correlated with dental caries of both dentitions among study group with significant correlation (P<0.05) between IL - 6 and D2, while they were correlated positively with dental caries of both dentitions among control group with highly significant correlation (P<0.01) between IL - 6 and D3 and significant correlation (P<0.05) between IL - 6 and d4. Salivary calcium was correlated positively highly significantly (P<0.01) withDMFS and significantly (P<0.05) with D4 among control group. Salivary magnesium was correlated positively significantly (P<0.05) with DMFS and D2 among study group; also it was correlated negatively highly significantly (P<0.01) with d3 amongcontrol group. Salivary phosphorus was correlated significantly (P<0.05) in positive direction with d3 among study group; also it was correlated highly significantly (P<0.01) in negative direction with DMFS and significantly (P<0.05) in positivedirection with d3 among control group.

المستخلص: Back ground : Healing socket consists of three new tissue components; epithelium, connective tissue, and bone tissue. Interactive dynamic changes take place between these 3 components during healing period.During the process of healing of the extraction socket the following events occur : firstly, a blood clot (mainly blood cells and network of fibrin) forms and fills the empty socket. Then, the blood clot matures and is organized by the formation of granulation tissue (rich in newly formed vascular structure, abundance of inflammatory cells. The granulation tissue replaces the blood clot completely by the seventh day. After 20 days, the granulation tissue was replaced by collagen, and bone began forming at the base and the periphery of the extraction socket. Epithelium covers the newly formed bone that filled the socket.The healing cascade of all wounds ultimately requires neovascularization, collagen deposition, and collagen constriction by myofibroblasts. Neovascularization in the adult is known to occur by two distinct processes, angiogenesis and vasculogenesis which needs for expression of VEGF.Aim of the study : Histological ,Histomorphometrical and immunohistochemical studies to evaluate the effect of local application of exogenous VEGF/collagen I separately and as a combination in socket healing.Materials and Method : Sixty male Albino Wistar rats were subjected for a surgical tooth extraction of upper 1st molar of both sides ( right side was considered as experimental site ,while left be the control one).The animals were divided into following groups according to the applicable of biomaterials.A. Control group the tooth socket treated with 1?L of normal salineB. Experimental group includes• Group I contains (20) rats, the tooth socket treated with 1?L of VEGF• Group II contains (20) rats the tooth socket treated with 1?L ofcollagen type I• Group III contains (20) rats, the tooth socket treated with 1?L of a combination of VEGF and collagen I. Each group is composed of 20 rats that will be studied in four periods 3,7,14,28 days (5 rats for each period).The specimens were studied histologically histomorphometrical and immunohistochemical identification of fibroblast growth factor 2 (FGF2) and tissue non specific alkaline phosphtase (ALP).Results : 1. Histological findings for all groups illustrate formation of blood clot at 3 days.2. Granulation tissue appears in all groups at 7 days period, and new bone is demonstrated in collagen group and a highly cellular woven bone with active proliferative osteoblast and newly blood vessel is detected in combination group.3. At 14 days new epithelization and new bone trabeculae with fibrous tissue are presented mostly in all groups but with different constitution.4. At 28 days all groups show reepithelization but in different thickness, and with newly bone apposition and with different maturity.5. For positive cells expressed ALP VEGF group records a high mean values at 3,14,28 days periods and with high differences in comparisum to other groups while control group reports a high mean value at 7 days.6. For positive cells expressed FGF2.Control group illustrates a high record for the mean of positive cells expressed FGF2 at 3,7days periods and with high differences in comparisum to other groups, while combination group reports a high mean value at 14 days.7. Results demonstrated that in most periods for each group ,whenever ,ALP is a high value in expression ,records a low expression in FGF2.Conclusion : Results ,high lighted on the effect of local application of VEGF in extracted tooth socket that facilited epithelization ,while combination of (Collagen and VEGF ) shows a high mineralization zone.

المستخلص: Background : Breast cancer is the commonest type of malignancy worldwide and in Iraq. It is a serious disease that affects the general health and cause systemic changes that affect the physical and chemical properties of saliva leading to adverse effects on oral health.Aims of the study : The aims of this study were to assess the oral health condition (including dental caries, oral cleanliness and periodontal health condition), to evaluate the changes in salivary flow rate and to assess the concentration of tumor marker CA15 - 3 and selected elements (calcium, phosphorus, zinc, copper, total proteins) in saliva and their relation to oral variables among breast cancer women in comparison to control group.Subjects, Materials and Methods : The total sample consisted of 60 women aged 35 - 45 years attending Al - Kadhemyia Teaching Hospital. Those comprised 30 women newly diagnosed with breast cancer before starting treatment and 30 women without clinical signs and symptoms of breast cancer as a control group.Diagnosis and recording o f dental caries was done by using DMFS indexaccording to the criteria of WHO (1987). Plaque index of Silness and Loe (1964) and calculus component of Ramfjod index for periodontal disease (1959) were applied to assess oral cleanliness. Periodontal disease was evaluated using the gingival index (Loe and Silness, 1963) and loss of attachment level (Ramfjord, 1959). Stimulated salivary samples were collected and salivary flow rate, salivary CA15 - 3, calcium, phosphorus, zinc, copper ions and total proteins were determined.Results : Results showed that caries experience (DMFS) was higher among the study group compared with the control group but the difference was statistically not significant. The mean values of plaque index, calculus index, gingival index and loss of attachment were higher among the study group than the control group with a highly significant difference (P<0.01).The salivary levels of CA15 - 3 in breast cancer patients were higher than that of the controls with a highly significant difference (P<0.01). All the correlations between salivary CA15 - 3 and dental caries and periodontal diseases were statistically not significant.The salivary flow rate was lower among the study group than control group with a highly significant difference (P <0.01). Higher concentrations of salivary phosphorus, copper and total proteins were recorded among study group compared to control with statistically highly significant differences concerning phosphorus and copper (P<0.01). On the other hand, salivary calcium and zinc were lower among study group compared to control group with statistically highly significant difference concerning zinc (P<0.01). All the correlations between the caries experience and salivary constituents in the study and control groups were weak and not significant except the correlation with total proteins in the control group which was significantly positive. Concerning the correlations of oral hygiene and periodontal disease with salivary constituents, the study showed that all the correlations were weak and not significant except the correlations between the total proteins with loss of attachment in study group and with dental plaque in control group which were significantly positive relations.Conclusions : This study showed that the breast cancer patients had poor oral hygiene and higher rates of periodontal diseases and dental caries, therefore special preventive programs need to be designed for this group of patients. Also the results of this study could support the concept that salivary oncentrations of CA15 - 3 might serve to be used in the detection of breast cancer and/or the po operative follow - up of patients under treatment for carcinoma of the breast

CT scan image for this region can provide accurate features about the border, position of incisive canal and status of buccal bone anterior to this canal.Aim of the study : To study for the effect of gender, age and tooth loss in area of maxillary central incisors teeth on the dimensions of the incisive canal and buccal bone anterior to the canal using spiral computed tomography.Subjects, Materials and Methods : The sample consisted of prospective study for 156 subjects of both gender. The sample were divided into two groups, 120 dentate group (60 male and 60 female) with age ranging from (20 - 70) and 36 edentate group(with missing both maxillary central incisor) (18 male and 18 female) with age ranging from (50 - 70), which was further divided into two group according to the duration of maxillary central incisorsteeth loss, long duration (5+) years which consists of 26 subjects and short duration (<5 years) which consists of 10 subjects. All subjects attended to Baquba Teaching General Hospital in Diyala for Computed Tomographic scan investigation for different Maxillofacial diagnostic purposes from November/2013 to April/2014.Using sagittal section of computed tomography scan, the following measurementswere done : A - The diameters of incisive canal were measured at crestal, middle and apical level and the total mean value of canal diameters was calculated. B - The length of incisive canal.C - The distance of buccal bone anterior to incisive canal at crestal, middle and apical level and the total mean value of buccal bone distances was calculated. D - The length of buccal bone anterior to incisive canal from the apical measurement of buccal bone to the alveolar crest. The measuring unit was in millimeter in all measurements.Result : Gender had moderately strong effect on the dimensions of incisive canal and buccal bone anterior to this canal, the mean values begin generally higher for male as compared to female for both control and cases group. Absence of maxillary central incisors decreased incisive canal length and buccal bone dimensions with mean values begin higher in control group than that in cases group, the effect of teeth loss on these selected measurements seem to be strong ;however, canal diameter remain unchanged with dental status and there was no effect of teeth loss on this parameter.There was a moderately strong to strong effect of the duration of maxillary central incisors teeth loss on canal length and buccal bone dimensions with mean values being significantly lower in long duration (5+) years than that in short duration (<5 years) while it had weak effect on incisive canal diameter for both gender. The results showed that there was no significant linear correlation between age and all selected measurements in male and female for both control and cases group. Conclusion : CT scan is a valuable tool to evaluate the anatomic variation at the examined area in the current study, gender and dental status are important factors that can affect incisive canal characteristics and amount of bone anterior to the canal. Clinicians should perform careful planning using CT scans before performing dental implant surgeries in premaxillary region.

المستخلص: Bone density is a major factor that affect mini implant primarily stability. No Iraqi studies had been evaluated bone density related to mini - implant placement for orthodontic anchorage at age 13 - 15 years.The present research aims to evaluate gender, side and site differences in the bone density at various orthodontic implant sites for the maxillary alveolar bone (cortical; buccal and palatal and cancellous).The sample of this study consisted of CT images for patients who were attending Al. Shaheed Ghazi Al - Hariri Hospital/the Computerized Tomography department from January 2014 until May 2014. Twenty nine individuals (16 males and 13 females) had subjected to clinical examination, then 64 - multislice computed tomography scan data were evaluated and bone density was measured in Hounsfield unit at 21 points (9 points for each side and 3 points between the right and left central incisors).The results obtained showed that there were no significant differences in bone density between males and females and between the left and right sides. There are no significant differences in bone density between the maxillary buccal cortical bone and the palatal cortical bone except at lateral incisor and canine point where the palatal side had higher bone density than buccal side. The mean bone density of the cancellous bone in the anterior part was higher than that in the posterior of the maxilla.These differences in bone density between and within regions of the maxilla must be considered when placing mini implants and may provide valuable information when selecting sites, size, angle and placement methods for mini implant in the dental arch.

المستخلص: Background : Depression is a common mental disorder that presents with depressed mood, its affect oral health through its effect on salivary function. The aims of this study were to assess the relation of depression status on prevalence and severity of dental caries and gingival inflammation among students aged 15 years in relation to salivary physical (flow rate and viscosity) and chemical characteristics concentration of (total protein, zinc, copper, chromium and lithium).Materials and methods : The total sample involved 800 students (males and females) aged 15 years old that were selected randomly, the depression status was measured using Children Depression Inventory (CDI) index that divided the students with depression into four groups according to severity of depression (low or average grade, high average grade, elevated grade and very elevated grade). The diagnosis and recording of dental caries was made by using Decay, Missing, Filled surface index (DMFs), according to the criteria of Manji et al (1989), while gingival condition was evaluated by using the gingival index by L?e and Silness, (1964). Salivary samples were collected under standardized condition from 30 students with very elevated grade and 30 students with low average grade, and then analyzed for measuring salivary flow rate and viscosity, in addition to the estimation of salivary elements (total protein, zinc, copper, chromium and lithium).Results : The prevalence of depression was 100%. The DMFs was lower among students with high average grade than other grades of depression with nonsignificant difference. The severity of dental caries was higher among students with elevated grade concerning D1, D3 and in very elevated grade of depression concerning D2, D4 with highly significant among D4 (P = 0.01). The prevalence of gingivitis in present study was found to be 100%, mild gingivitis occurrence found higher among low or average grade than other grades, but moderate gingivitis was more among very elevated grade, while sever gingivitis was absent. Salivary analysis demonstrated that the salivary flow rate was non significantly higher among students with low or average grade of depression than very elevated, while the viscosity of saliva was not significantly higher among students with very elevated grade. The data analysis of salivary elements found that the total protein and copper was higher among students with very elevated grade while other elements show the opposite result with significant difference concerning copper and zinc among females in very elevated grade, while others with not significant.Conclusion : The results of the current research revealed that caries experience and gingival inflammation increase with depression that has an adverse effect on salivary physicochemical characteristics. There were changes in saliva variables between low or average grade and very elevated grade of depression.

المستخلص: The formation of white spot lesions around fixed orthodontic attachments is a common complication during and following fixed orthodontic treatment, which hinder the results of a successfully completed case.The aim of the study was to assess the effectiveness of the Caries Infiltrant (ICON®) on prevention of caries on the smooth enamel surface when applied alone or combined with conventional adhesives. To achieve this objective, seventy eight human premolar enamel discs were randomly assigned to six groups (n=13). The discs were etched and treated with resins of different monomer content forming the following groups : (1)Untreated etched samples served as the negative control, (2) ICON® (DMG), (3) Adper™ SB 2 (3M ESPE), (4) Heliobond (Ivoclar Vivadent), (5) ICON®+ Adper™ SB 2 and (6) ICON®+ Heliobond. Specimens were subjected to demineralization by immersion in hydrochloric acid (pH 2.6) for 18 days. Calcium dissolution into the acid was assessed by photometric test via spectrophotometer at 24 hour intervals.The results revealed that, there was a highly significant difference between the sealed groups and the unsealed (untreated) one (p?0.00) indicating that the unsealed specimens showed the highest amount of Ca ion loss among all other groups. Additionally, there was no significant difference between untreated specimens and the ICON® sealed ones. While, Heliobond decreased the Ca ion loss significantly compared to the untreated specimens and Adper™ SB 2 performed significantly better than both ICON® and Heliobond. Furthermore, the combination of ICON® with either Adper™ SB 2 or Heliobond served as the best protective measures and maintained the protective effect during the whole experiment period.Therefore, within the limitations of this in vitro study, it could be concluded that the use of low - viscosity Caries Infiltrant prior to application of the tested conventional adhesives increases their protective effect against demineralization.

X - ray diffraction (XRD) analysis , scanning electron microscope examination were carried out on the nitride surfaces of the plates ,contact angle measurement (Wettability) was done by applying drop of saline and blood on the nitrided surface and compared to control. The femur of 10 white New Zealand rabbits were chosen as implantation sites. The femur of each rabbit received two screws, one plasma nitride treated and one non treated and a total of 40 screws were implanted. Torque removal test was performed(by digital torque meter) to measure bond strength between implant and bone, after 2 and 6 weeks healing periods. For each period of time 18 screws were tested for the torque required to remove the implant from the bone and 2 screws were kept for histological examination. Results : The results revealed that the mean removal torque values for the plasma nitride treated implants was significantly higher than the non treated implants and over the two periods of time. There was an increase in the bond strength (torque value) of bone - implant interface with time. The torque removal force for plasma nitride implants after 2 and 6 weeks was (30.22, 59.56 N.cm ,respectively) and for non treated implants after 2 and 6 weeks were ( 23.61,56.11N.cm, respectively) and new bone formation ratio for plasma nitride treated implants after 2 and 6 weeks(3.36, 4.72 , respectively) and for non treated after 2 and 6 weeks(1.56, 3.04, respectively). Conclusion : Plasma nitriding of Cp Ti screws significantly increased the torque removal value and new bone formation ratio at 2 and 6 weeks compared with the non treated implant.Dental implant, Osseointegration, Digital torque meter

المستخلص: The study was conducted to assess the distribution, prevalence, severity of malocclusion and orthodontic treatment need in Baghdad governorate in relation to gender and residency, and whether it has increased or not over 12 years by comparison with previous survey in Baghdad.A multi - stage stratified sampling technique was used in this investigation to make the sample a representative of target population. The sample consisted of 2700 (1349 males and 1351 females) intermediate school students aged 13 years representing 3% of the total target population.A questionnaire was used to determine the perception of occlusion and orthodontic treatment demand of the students and the assessment procedures for occlusal features by direct intraoral measurement using veriner and an instrument to measure the rotated and displaced teeth. In summary the followingresults were obtained : 1 - 7.7% of the sample had some type of orthodontic treatment or consultation.2 - 39.1% of the students answered that they have malaligned teeth, being significantly more in female than males.3 - of the students who stated that they have malaligned teeth, 26% reported that they had crowded teeth, 26.6% had spaced teeth, 22.4% had protruded teeth and 25.7% had rotated and displaced teeth.4 - Regarding the answers of the effect of mal - aligned teeth, 70.3% answered that it affects their appearance, 17.7% chewing, and 7.7% speech while 4.1% answered that mal - aligned teeth did not affect appearance, chewing or speech.5 - the most common reasons for not seeking orthodontic treatment that the student thought that treatment is fear of pain (48.8%) and not important or not possible (25.8%).6 - One or more missing teeth due to extraction or trauma were found in 4.9% of the sample, and the most common extracted teeth were the first molars (1.6% mandibular and 0.9% maxillary). One or more rotated teeth were found in 38.3% of the sample; one or more displacement teeth were found in 19.6% of the sample.7 - The maxillary anterior region showed the highest prevalence of 2mm or more spacing (15.2%) and the mandibular anterior region showed the highest prevalence of 2mm or more crowding (12.6%); a maxillary central diastema of 1mm or more was found in 18.1% of the sample with a mean of 0.306±0.015mm.8 - Angle’s class I occlusion was found in 78.29%of the sample, class II in 19.5% (17.2% division 1 and 2.3% division 2) and 2.3% had class malocclusion (1.6% postural and 0.7% true). The mean overjet of the sample was 3.31± 0.04 mm. The mean overbite was 2.99±0.03 mm,9 - Midline shift (?1mm) was found in 54.3% of the sample (28% to the right and 26.3% to the left side).Soft tissue impingement was found in 3.3% (3% palatally and 0.3% labially). Normal lip form was found in 86.6%, contracting lip form in 10.1% and lip trap in 3.3% of the sample.10 - The DAI scores registered in this study ranged between 13 and 65 with a mean of 23.234±0.12. 7.3% with treatment highly desirable, and 4.5% with treatment mandatory.Significant changes in the proportions of malocclusions as a whole in school children were found over the last decade; also increase the need for orthodontic treatment among adolescents in the Baghdad commune and low perception level of the Baghdadi children to their own occlusion and the demand on treatment was remarkably low. This data will be useful for public oral health service and emphasize the need for orthodontic treatment among adolescents in Baghdad and stressing on the role of oral health education to encourage the children to undergo orthodontic treatment.

Previous reports indicated that contaminated impressions can cross infect gypsum casts that were poured against them, however immersing or spraying commonly used alginate impression material with disinfectant may adversely affect the accuracy of dies or casts obtained. Objective : The objective was to evaluate the effect of (0.25%,0.5%,1%, 2%, 3%, 4% ) of (NaF) addition on the self - disinfection of alginate impression material and its effect on setting time, tear strength, dimensional change and accuracy of alginate impression materials and to compare this with CHX containing alginate material related to the same properties mentioned above.Materials and methods : A total No. of 800 specimens were prepared in this study, they were divided into five main groups according to the type of the tests used (tear strength test, setting time test, dimensional change test, dimensional accuracy test, and bacteriological tests (Streptococcus mutans and Candida albicans).Six concentrations of NaF from (0.25% to 4%) and 0.1% CHX gluconate were mixed with alginate impression material and compare it with control alginate without disinfectant. Results : The self - disinfecting impression material containing NaF showed a total kill of microorganisms immediately after impressions were made.Tear energies for all experimental impression materials were greater than those of the control products. There were no statistically significant differences between the dimensional change tests and also reproduction of detail test, that contained (NaF) and one that did not. With regard to setting time of the impressions, statistically significant reduction were seen between the control and experimental groups of alginate impression materials. The experimental material that did not contain (NaF) had a considerably longer setting time than all of the other materials tested.Conclusion : the use of (NaF) and CHX disinfection when taking alginate dental impression is a good measure in reduction of contamination and cross infection and have a minute effect on dimensional stability and is recommended as step in protecting dentist and dental laboratories teams.

المستخلص: Background : Dental caries is a quite prevalent disease in Iraqi community however, baseline data concerning this disease and related etiological and risk factor are limited, concerning in selected geographic area in Iraq.Aims of study : This survey was made to investigate the prevalence and severity of dental caries in Al - Mussayb city/ Babylon governorate, the co - relation of this disease was studied with nutrition status and dietary analysis, oral cleanliness and parent'seducation among (16 - 18) years old in high school girls.Materials and Methods : The survey was conducted among high school girls, with a total sample of 900. Diagnosis and recording of dental caries and treatment needs were done according to the criteria of WHO. Dental plaque was assessed by using Plaque Index following the criteria of Silness and Loe. Nutritional status was recorded according to Body Mass Index indicator by applying anthropometric measurement. Dietary analysis was according to Dietary Guidelines in primary health centers in Iraq. Parent's education was divided in to five levels according to modification to educational status of Kuppuswamy's scale.Results : The prevalence of dental caries was (70.5%). The DMFS mean value was (4.94 ±SE 0.161) and the median was equal to (4.00) for the total sample. The DMFS value increased with ages with statistically highly significant difference (P<0.01), The highest percentage of examined girls were in need of one surface filling (60.8%), followed by those in need of two or more surface filling (36.6%). Result showed a weak positive highly significant correlation between plaque index and DMFS (r=0.315, P<0.01). A statistically highly significant difference in DMFS was recorded by different level of parent's education as a lower value of DMFS was seen among girls with high level of parent's education. Results showed statistically highly significant differences in the value of DMFS between different grade of Body Mass Index indicator (P <0.01, df=3), for total sample (11.7%) was malnourished and (65.77%) of girls was with normal weight. Statistically highly significant weak negative correlation was seen between DMFS and different food groups (fruits, vegetable, meat, grain and diary). A weak positive highly significant correlation between DMFS and sweet consumption was seen (r=0.155, P<0.01).Conclusions : Girls in high schools in Al - Mussayb city/ Babylon Governorate demonstrated a high prevalence of dental caries.

المستخلص: Molar - Incisor hypomineralisation (MIH) is one of the biggest challenges with great clinical interest for dental practice because MIH has a great impact on the oral health as consequently, on the quality of life of children. Currently, the etiology of MIH remains unclear and is thought to be acquired via multifactorial, systemic disturbances during amelogenesis. There is no previous study concerning school children aged 7 - 9 years in Al - Najaf govemorate in order to estimate the prevalence and severity of molar incisorhypomineralisation and the possible associated risk factors. Objective : To estimate the prevalence , severity and the possible associated etiological factors of molar - incisor hypomineralisation and also to study the correlation between body mass index and molar - incisor hypomineralisation.Patients and Methods : A cross sectional study was conducted at Al - Najaf Govemorate, data were collected during the period from January to the end of April 2014. study population included the primary school children aged, 7 - 9 years of both genders who attending the primary schools of Al - Najaf govemorate. Children having amelogenesis imperfecta, tetracycline staining or undergoing orthodontic treatment at the time of study, those with completely broken crowns of the first permanent molars, or those whose parent/guardians refusedto missed data or not get back the questionnaire were excluded from the study. Sample size was calculated according to the standard equation and a total of 600 children were enrolled. A structured self - administered validated arabic language questionnaire and an examination sheet was measured. Body weight and height were measured and the body mass index was calculated according to the standards. Dental material and supplies were used in examination, Prior to the clinical examination the participating children were given a toothbrush and fluoridated toothpaste to brush their teeth thoroughly under the supervision of the researcher. The demarcated hypomineralization was recorded according to the 10 point scoring system depended on the European academy of pediatric dentistry evaluation criteria. The severity was assessed according to the clinical evaluation of the examiner and the presence of opacities. Data of the studied group were entered and analysed by using the statistical package for social sciences (SPSS) version 21 and appropriate statistical tests were used to assess the differences and correlations between variables. Results : The response rate was 84. 7% and the highest was in the 9 - year - old children, the participants were 532 children, the prevalence of hypomineralisation defect was 22.9%. The prevalence of demarcated hypomineralisation was increased concomitantly with the age, and the 9 - yearold children were the more affected. The overall prevalence of molar - incisor hypomineralisation among boys was lower than girls; (17.3%) and 22.6%, respectively. Molar - incisor hypomineralisation was more frequent in normal body mass index children. The total number of teeth of the studied group was 1464. The number of affected teeth was 3 81 represented (26%) of the total number of teeth. The molar and incisors were most affected with White/creamy demarcated opacities with no posr eruptive enamel breakdown, (27.7% and 15.2%), respectively. The severely affected teeth were 33 teeth, represented 4.5% of the total number of teeth of the 122 children , severely affected molars were 25 (5.1 %) and the severely affected incisors were 8 (0.8%), (P=0.001), Obeseand overweight were more likely to have more severely affected teeth and the severity was also increased with the age of child. Conclusions and Suggestions : The prevalence of Molar Incisor Hypomineralisation among Iraqi schoolchildren of Al Najaf govemorate was 22.9%, it was more prevalent among girls, the 9 - year - old children , normal body weight children and urban residents. Molars were more affected with than incisors. It was more prevalent in maxillary than mandibular teeth. The severely affected teeth represented 4.5% of the total number of teeth of the 122 children. , molars were more severely affected than incisors. The more severely affected teeth reported inobese and underweight children. Further studies are suggested for further understanding of the etiological and risk factors of the disease.

المستخلص: Background : When prevention of dental caries fails, and a child is exposed to the risk of pain and infection, the disease must be managed to reduce this risk. There is a growing evidence supporting more 'biological approaches' for managing dental cariesin primary teeth. The Hall Technique is one of the biological approaches for managing caries in primary molars which involves sealing caries beneath preformed metal crowns (stainless steel crowns). The crown is cemented over the tooth without theuse of local anesthesia, caries removal, or tooth preparation. The clinical steps for the Hall Technique are straightforward but, as with all dental care provision, appropriate treatment planning for the procedure requires skill. The Hall Technique offers anothermethod of managing early to moderately advanced, active carious lesions in primary molars, with good evidence of effectiveness and acceptability.Aims of the study : This study was conducted to assess the possible local factors that might happen along with using this novel technique regarding the possible adverse effect of the increased occlusal - vertical dimension and the condition of the surrounding tissues.Also to assess the correlation between the rate of the successful outcome with the caries extension towards the pulp.In addition to evaluate the cost - effectiveness of the Hall Technique in comparison with the conventional restorations. Finally to estimate whether this technique can be performed efficiently by both the specialized dentists and general practitioners in terms of putting the appropriate treatment plan based on the radiographic assessment.Material and methods : A retrospective research was conducted, standardized bitewing radiographs of 100 patients between 3 - 9 years old were evaluated for marginal bone changes. The distance between the cemento - enamel junctions and the alveolar bonecrest was measured. The dentine was evaluated as well regarding the existence of clear band of dentine and the extension of the caries towards the pulp of the tooth. - The cost effectiveness was conducted by creating a scenario of the possible outcomes for the treatment decision whether it was Hall preformed metal crown or traditional restoration. Incremental cost - effectiveness ratio was calculated to find the savingamount value. - A panel consisting of five general practitioners and three specialized dentists weas asked to evaluate twelve bitewings radiograph presented to them and give their opinion whether these radiographs are suitable for Hall Technique or not.Results : The result of this presented study showed that there is decreasing in the distance between the cemento - enamel junction and alveolar bone level at the Hall PMCs treatment side between the before and after insertion periods.it also showed thatthere's no different bone level changes between the Hall preformed metal crown treatment side and its contra - lateral side regardless of its condition (Hall preformed metal crowns, no Hall preformed metal crowns). - A high rate of successful treatment is highly associated with observing a clear band of dentine but it is not associated with the carious extinction toward the pulp as long as a clear band of dentine can be seen. - The Hall Technique is more cost - effective by making more cost saving and more gained teeth. The Hall Technique can be performed efficiently by both the general practitioners and the specialized dentist.Conclusion : according on the results of this research it can be settled that there are no adverse effects of using Hall preformed metal crowns regarding the increase of occlusalvertical dimension and the periodontal condition also the Hall Technique is more costeffective and can be performed by specialized dentists as well as the general practitioners.

They have the ability to exert an interrupted force, convenience of use, compatibility to oral environment and cost effectiveness despite of the inherited disadvantage which is force degradation.This in vitro study was designed to evaluate the effect of alcohol presence in mouthwashes on force degradation of different configurations of clear elastomeric chains from Ortho Technology company which are : closed, short and long under the effect of time at different intervals (Initial, 1day, 1, 2, 3 and 4 weeks) with exposure to different chemical solutions.A total of (540) elastomeric chains of three different types (long, short and closed) transparent in color, with an initial length (19mm) and about 50% extension (29mm) were used for the study. These elastomeric chains was divided into four groups and exposed to different chemical solutions (Distilled water, Listerine Original alcoholic mouthwash, Listerine Zero alcohol mouth wash, Ethanol 26.9%) twice daily for 60 seconds each according to manufacturer's instructions to measure the amount of force degradation in different time intervals. These elastomeric chains were incubated in covered glass containers at 37C? for the entire testing period.The results of the present study showed that the elastomeric chains were greatly affected by time, the majority of force loss occurred after the first 24hr. then followed by a less steep gradient for the rest of the working period.We can conclude that alcoholic mouth wash (Listerine Original) causes an increase in force degradation of all types of elastomeric chains while alcohol free mouth wash (Listerine Zero) causes less force degradation of all types of elastomeric chains, additionally closed configuration elastomeric chains has the least percentage of force degradation than other configurations of elastomeric chains.

المستخلص: Background Chronic periodontitis is an inflammatory disease that affects the supporting tissues of the teeth and it is common among adults. Smoking is an important risk factor for periodontitis that induces alveolar bone loss. Alkaline phosphatase enzyme is involved in the destruction of the human periodontium. It is produced by many cells such as polymorphonuclear leukocytes, osteoblasts, macrophages and fibroblasts within the area of the periodontium and gingival crevice. Osteocalcin is one of the most abundant matrix proteins found in bones and the only matrix protein synthesized exclusively there. Small osteocalcin fragments are found in areas of bone remodeling and are actually degradation products of the bone matrix.Aims of the study 1. Investigate whether light smoker chronic periodontitis patients exhibit different salivary concentrations of Alkaline Phosphatase and Osteocalcin compared to the non - smoker counterpart and compare to light smoker and nonsmoker control groups and 2.Correlate the clinical periodontal parameters (plaque index, gingival index, bleeding on probing, probing pocket depth and clinical attachment level) to the biochemical findings in light smokers and non - smokers chronic periodontitis and control groups. 3. Estimation of the salivary PH and flow rate and correlate them with clinical periodontal and biochemical parameters. Materials and Methods Five ml of unstimulated whole saliva samples and fullmouth clinical periodontal recordings (plaque index, gingival index, bleeding on probing, probing pocket depth and clinical attachment level) were obtained from study groups (25 light smokers and 33 non - smokers subjects, both with chronic periodontitis) and control groups (8 light smokers and 13 non - smokers subjects, both with healthy periodontium). All subjects were systemically healthy males, with age range (30 - 50) years. Salivary Alkaline phosphatase and Osteocalcin levels were determined by Colorimetric and Enzyme - linked Immunosorbent Assay, respectively. Salivary PH and flow rate were also measured.Results Smoker chronic periodontitis patients revealed non - significant differences in clinical periodontal parameters with non - smoker counterparts (P > 0.05) in terms of plaque index, probing pocket depth, clinical attachment loss, salivary PH and flow rate, with slight increase in plaque index value in smoker chronic periodontitis group(1.42±0.46) than non - smoker chronic periodontitis group (1.38±0.50), while there was slight decrease in mean value of probing pocket depth (3.90±1.78), clinical attachment level (3.22±0.93) and PH (7.58±0.50) in smoker chronic periodontitis group than non - smoker chronic periodontitis group (4.27±1.98), (3.74±0.85), (7.73±0.33) respectively. Flow rate value was higher in smoker chronic periodontitis (4.80±2.69) than non - smoker chronic periodontitis group (4.67±2.09). While there were highly significant differences in terms of gingival index and bleeding on probing (P ? 0.01). Osteocalcin levels were lower in smoker chronic periodontitis group (0.13±0.20) than non - smoker chronic periodontitis group (1.09±2.26) with significant difference (0.05 ? P > 0.01). Highly significant, strong, positive correlations were found between Osteocalcin concentration with plaque index and PH in non - smoker control group. Correlation analysis between Osteocalcin concentration and flow rate in smoker chronic periodontitis group revealed a significant, moderate, positive correlation.Mean of Alkaline phosphatase level was lower in smoker chronic periodontitis (11.14±4.53) than non - smoker chronic periodontitis (11.45±4.17) with a nonsignificant difference, while there was a significant difference in Alkaline phosphatase concentrations between smoker and non - smoker control subgroups.Correlation analysis between ALP concentration and clinical periodontal parameters (plaque index, gingival index, bleeding on probing, probing pocket depth and clinical attachment level) in chronic periodontitis smoker group appear non - significant, weak,negative and related non - significantly, weakly, positively with PH and flow rate. Clinical attachment level and PH correlated non - significantly, weakly, negatively with Alkaline phosphatase concentration, while plaque index, gingival index, bleeding on probing, probing pocket depth and flow rate related non - significantly, weakly, positively with Alkaline phosphatase concentration in chronic periodontitis non - smoker group. There was a significant, moderate, negative correlation between salivary PH and bleeding on probing and significant, weak, negative correlation regarding probing pocket depth in smoker chronic periodontitis group.A significant, weak, positive correlation between salivary flow rate and clinical attachment level was found in non - smoker chronic periodontitis group.There were non - significant differences between smoker chronic periodontitis and smoker control groups in terms of salivary PH, flow rate, Osteocalcin and Alkaline phosphatase concentrations. There were non - significant differences between non - smoker chronic periodontitis and non - smoker control groups in terms of PH, flow rate, Osteocalcin and Alkaline phosphatase concentrations. There were non - significant, weak increase in Alkaline phosphatase concentration compared to the increase in Osteocalcin concentration in smoker and non - smoker chronic periodontitis and smoker control groups, while there was a nonsignificant, weak decrease in Alkaline phosphatase concentration with increase in Osteocalcin concentration in non - smoker control group. Conclusion Within the limits of this study, it may be suggested that suppression of salivary Osteocalcin levels by smoking and weak increase in Alkaline phosphatase in smokers groups, may explain the deleterious effects of smoking on periodontal healthstatus.

المستخلص: The objectives of this study was to evaluate the effect of addition of Multi - Wall Carbon Nano ubes(MWCNTs) of different concentration (0.05 mg/mL - 1, 0.25 mg/mL - 1, 0.5 mg/mL - 1and 1 mg/mL - 1) with on either (dimethyl sulphoxide DMSO and distilled water DW) on tooth enamel. It is intended to evaluate enamel microhardness in (Kg.m - 2) and enamel thermal conductivity before and after the application of (MWCNTs).Ninety mandubular first premolar were prepared for this study. They were divided into two groups. The first group contains 54 sample to measure the microhardness of the enamel. To overcome the teeth curvature in microhardness measurement, the position of indenter were optimized to coincide linear buccal surface. The second group contains 36 sample to measure the thermal conductivity of the enamel were prepared by cutting enamel part in triangle form with a base of 7. 5 mm , height of 9. 5 mm and thickness of 2 mm according to the requirements of the Fourier’s law by abrasive disk.The results enamel microhardness showed that a significant increase in the enamel microhardness and enamel thermal conductivity for groups 0.05 mg/mL (group B) , 0.25 mg/mL (group C ) , 0.5 mg/mL (group D ) and 1 mg/mL (group E ) compared with control group (group A ) in DW media and DMSO media. The results showed a significant increase in the enamel microhardness and enamel thermal conductivity for polished samples compared with unpolished samples in DW media and DMSO media. DMSO media increases the enamel microhardness and enamel thermal conductivity more effectively than DW media. Scanning electron microscope showed a significant deposition of MWCNTs in the depth of the enamel exceeding the surface layer. The polished specimens had more deposited MWCNTs compared with non - polished specimens. However, the nano dimensions with conjunction with pre - chemical treatment enabled the MWCNTs to penetrate and settle down inside the enamel.The final conclusion highest mean value obtained was 1 mg/mL (group E ) in the enamel microhardness and enamel thermal conductivity suspension in DW media and DMSO media.

المستخلص: Background : Dental implants provide a unique treatment modality for the replacement of lost dentition. The clinical success of implants has been achieved not only because of the mechanical strength or cellent biocompatibility of the implant material but also owing to other characteristics such as surface properties.Aims of the study : The goal of this study was to consider the role of nanoscale topographic modification of commercial pure titanium dental implant using a thermal deposition and chemical etching methods for the purpose of improving osseointegration.Materials and methods : Commercial pure titanium rod was machined into 40 dental implants. Each implant was machined in diameter about 3mm, length of 8mm (5mm was threaded part and 3mm was flat part). Implants were prepared and divided into 4 groups according to the types of surface modification method used : 1st group (10 implant) machined surface i.e remained without nano surface modification (control),2nd group include (10 implant)etched with 15N H2SO4 and 30% H2O2,3rd group include (10 implant)were coated with nano CPTi powder by thermal evaporation deposition technique,4th group (10 implant)were chemically etched with H2SO4 and H2O2 method to obtain a nano feature then coated with nano powder of CPTi by thermal evaporation deposition technique.Nano surfaces were characterized by scanning electron microscope (SEM), Xray diffraction (XRD), atomic force microscope (AFM), thickness measurement and microscopical examination for the invitro experiments. For the invivo part of study, the tibia of 10 white New Zealand rabbits were chosen as implantation sites. The tibia of each rabbit received two screws. Biomechanical test was performed after two weeks healing periods. Implants from eight animals were tested for the torque required to remove the implantfrom the bone and the other two animals were prepared for histological examination.Results : For invitro results, scanning electron microscope showed that chemical etching of Ti substrate becomes highly porous and has surface consisting of nano_sized pits and the combination of chemical etching and thermal evaporation of nano Ti showed nano rod like structure. The results of removal torque means value after 2 weeks of implantation showed that, there was a gradual increase in the removal torque mean values in the studied groups as a follow (M±SD) : 12.625 N.cm ± 0.517 machined surface, 30.500 N.cm ± 4.071 chemically etched, 46.875 N.cm ± 5.938 nano CPTi coating by thermal evaporation method, 51.250 N.cm ± 5.175 combination method of chemical etching and nano CP Ti coating. In addition, the histological analysis showed improved quality of bone in response to the nano surface modified screws, especially the combination treated implants show a well developed mature bone characterized by a well developed bony threads and haversian canal. Conclusion : The biomechanical and biological properties of the bone - implant interface associated with the nano modified implants were improved comparing to the unmodified implants. All nano modified CP Ti seems to be well tolerated by the bone since no adverse tissue reaction was evident and they have better mechanical properties and excellent biocompatibility through the improved performance regarding the bone implant contact area than the untreated implants.

المستخلص: Background : University dental students perceived a higher level of stress prior to each examation especially the final. Therefore, there is a need for a useful noninvasive biomarker for measuring acute stress in those students. Many studies considered salivary alpha - amylase as a stress biomarker that is most often used in conjunction with cortisol. Understanding of the exact association between these two salivary stress markers are poorly established. Using a Helkimo anamnestic and clinical dysfunction scoring index for temporomandibular disorders can give a better insight about the association between these markers and temporomandibular joint disorders.The aims of study : was to evaluate the levels of salivary alpha - amylase and salivary cortisol in stressed students with temporomandibular joint disorders and the differences between these markers in relation to temporomandibular joint disorders students. This might give a better understanding to the role of psychological stress as an etiological factors for developing temporomandibular joint problems.Subjects, materials and methods : A total eighty (60 study and 20 control) participants aged between 20 and 24 years, were recruited for this study. The participants were final year undergraduate Baghdad university dental students who were examined and gave saliva samples before their final academic examination. Those with temporomandibular joint disorders problems were exposed to psychological stress and included on the study. While, those who were taking corticosteroids or hormone supplementation including oral contraceptives, or having history of head injury, orthodontic treatment, occlusal disharmonies and muscle tenderness due to systemic diseases as fibromyalgia, or having more than 2 missing posterior teeth were excluded. Salivary assay kits (alpha - amylase and cortisol) were used to measure those variables and a Helkimo anamnestic and clinical dysfunction scoring for temporomandibular joint disorders were utilized in this study.Results : There is statistically a highly significant difference of the salivary cortisol and salivary alpha - amylase in the patient group( stress with temporomandibular joint disorders) and control group. The absence of correlation between these salivary markers was founded. Correlation analysis of salivary cortisol with Helkimo anamnestic and clinical dysfunction score shows positive association expressed by significant probability of error (p) value while for salivary alpha - amylase there is no association.Conclusion : This study demonstrates that salivary alpha amylase can be used as a stress biomarker in conjunction with cortisol to assess temporomandibular joint problems due to psychological stress in university students.

المستخلص: Thalassemia is a hereditary anemia resulting from defects in hemoglobin production. Beta Thalassemia, which is caused by a decrease in the production of beta globin chains, affects multiple organs and is ssociated with considerable morbidity and mortality. Aims of the study : The aims of this study were to study the oro - facial manifestations in beta thalassemia major patients and evaluation of the oxidative stress status in serum and saliva represented by malondialdehyde as xidative stress indicator and also assessment of serum and saliva antioxidants which are ceruloplasmin and uric acid in beta thalassemic patients with and without periodontitis and compared that with the healthy individuals in addition to investigate the relation between the clinical findings and laboratory investigations.Methods : Eighty seven (87) subjects were consented and contributed in this study, twenty eight (28) thalassemic patients with periodontitis, thirty (30) thalassemic patients without periodontitis and twenty nine (29) healthy subjects that were age matched with the patients. Oral examination has been done for each subject. Serum and saliva sample have been taken from each subject for analysis, to study malondialdehyde as oxidative stress and antioxidants ceruloplasmin and uric acid.Results : Malocclusion was the most common prevalent oro - facial manifestations (60%), followed by rodent face (35%), brown pigmentation of oral mucosa (23%) and incompetent lip (8%). The mean serum and saliva malondialdehyde were significantly higher in thalassemic patients with periodontitis than that in thalassemic patients without periodontitis and healthy subjects (p<0.001), while the mean serum and saliva ceruloplasmin were significantly higher in control group than that in other study groups (p<0.001). The mean serum uric acid was significantly higher in thalassemic patients without periodontitis than that in thalassemic patients with periodontitis and healthy subjects (p<0.001) and the mean saliva uric acid was significantly higher in thalassemic patients without periodontitis (p<0.05) compaired with thalassemic patients with periodontitis and healthy subjects. The results of this study showed that there were no significant correlation between serum and saliva malondialdehyde in any of study groups, while there was a positive significant linear correlation between serum and saliva ceruloplasmin in thalassemic patients with periodontitis (p<0.05), a negative significant linear correlation in healthy subjects (p<0.05) , a positive significant linear correlation in thalassemic patients without periodontitis (p<0.001). The results showed that there was a positive significant linear correlation between serum and saliva uric acid in thalassemic patients with periodontitis (p<0.05), a positive significant correlation in thalassemic patients without periodontitis (p<0.001) and no significant correlation between serum and saliva in healthy subjects. On the other hand there were no significant correlation between serum and saliva (malondialdehyde, ceruloplasmin and uric acid) and clinical attachment loss (p>0.05), except a positive significant linear correlation between clinical attachment loss and salivamalondialdehyde (p<0.05) was found. Conclusions : Malocclusion was the most prevalent oro - facial manifestations of beta thalassemia major patients. Oxidative stress play a significant role in the pathogenesis of beta thalassemia ,which was the main cause of red blood cells destruction represented by significant elevation of serum and saliva malondialdehyde and significant reduction of ceruloplasmin. Also oxidative stress remain contributing factor in periodontal tissue destruction, which was appeared as a significant increased level of saliva malondialdehyde and decreased saliva ceruloplasmin in patients with periodontitis and there was a significant correlation between saliva malondialdehyde and clinical attachment loss

المستخلص: Background : Bones are rigid organs that constitute part of the endoskeleton of vertebrates. They support and protect the various organs of the body, produce red and white blood cells and store minerals. Bone tissue has been shown to contain numerous cell - to - cell signaling peptides called growth factors. These growth factors are thought to have important regulating effects for bone remodeling and bone healing. Several growth factors are expressed during fracture repair. of these, vascular endothelial growth factor (VEGF), is of particular interest because of its ability to induce neovascularization (angiogenesis). The responses to exogenous VEGF observed that a slow - release formulation of VEGF, applied locally at the site of bone damage, may prove to be an effective therapy to promote human bone repair. N - acetyl glucosamine is a monosaccharide, which are the derivatives of carbohydrates, it helps the body in making several other chemical agents which are used in the formation of bones, muscles and cartilages.N - acetylglucosamine is very effective in providing support for the skeletal system of the humans, and may provide strength to the ligaments and joints, and the skin remains fresh and glowing. Aims of study1. To identify role of local exogenous application of vascular endothelial growth factor and application of N - acetyl - D glucose amine as a biomaterial in bone healing.2. To analyze the expression of Vascular endothelial growth factor, tissue non specific ALP and bone matrix protein (collagen - 1) by immunohistochemistry in created bone defect after application with different biomaterials in a rat model. Materials and MethodsIn this experimental study fifty four male Albino rats, weighting (300 - 400) gram, aged (6 - 8) months were used and maintained under control conditions of temperature, drinking and food consumption. The animals were subjected for a surgical operation of medial sides of both tibial bone ( right side was considered as experimental site ,while left be the control one). The animals were divided into following groups according to the applicable growth factors.A. Contol group the bone defect treated with 1?m of normal saline and its number represented the all number of the following experimental groups as the left side of each animal considered to be the control.B. Experimental group includes ? Group I contains (18) rats, the bone defect treated with 1?ml of Vascular endothelial growth factor. ? Group II contains (18) rats the bone defect treated with 1?ml of Nacetyl D - glucosamine.? Group III contains (18) rats, the bone defect treated with 1?m combination of (VEGF& N - acetyl D - glucosamine).Every single group composed of 18 rats that studied in three periods 3,7,10 days (6 rats for each period). Histologic and immunohistochemical evaluation for VEGF, alkaline phosphatase and collagen type 1 were carried for all animals.Results : A. For Histological findings An early apposition of osteoid tissue was detected in VEGF group. Osteoblast, osteocyte and osteoclast cells count were demonstrated to be with high mean value in VEGF group followed by N - acetyl Dglucosamine group in periods 3,7,10 days post operative of bone defect.Inflammatory phase as first step in bone healing was detected in all study groups at 3 day, and combination group records highest value in the mean of inflammatory cell count in comparisum to others. Finally thestudy demonstrated that exogenous VEGF/ N - acetyl D - glucosamine has a direct effect on osteoblastic activity.B. For Immunohistochemical findings The present result showed positive expression of VEGF by bone marrow stromal cells, adipocytes, mesenchymal stem cells, precursor endothelial cells, and bone cells include osteoblasts and active osteocytes in different periods in all groups but in different score. Therefore, our primarily data provide evidence that VEGF activity is essential for appropriate bone formation and mineralization in response to injury. At day 3, bone marrow stromal cells in combination group records highVEGF expression, VEGF group is the second. At 7 and 10 day VEGF group records a highest VEGF expression in comparisum to other groups. The data showed a high expression for ALP during the formative stages of bone in all groups except combination group shows the lowest count for positive cells that expressed ALP.the present results showed that at day 3, bone marrow stromal cells in VEGF and N - acetyl D - glucosamine group records high collagen type I expression. Conclusion : the study demonstrated that low application of VEGF / Nacetyl D - glucosamine could be an effective therapeutic for bone injuries, these data are promising for a possible future clinical usage.

المستخلص: Petroleum is perhaps the most important substance consumed in modern society. Petroleum is unique and s a complex mixture of thousands of compounds. Oil refinery workers are continuously exposed to numerous hazardous materials and working conditions that place them at continuous risk of injury and death.Petroleum contains the heavy metals as a natural constituent or as additives. The main threats to human health from heavy metals are associated with exposure to lead, cadmium, mercury and arsenic. Several carcinogenic metals such as arsenic, cobalt, chromium, lead, mercury, and nickel induce redox reactions in living systems. These metals induce the production of reactive oxygen species in both in vivo and in vitro systems. These radicals have rendered oxidative damage to deoxyribonucleic acid, proteins, and lipids. Secretory immunoglobulin A is the main immunoglobulin found in mucous secretions from the tear glands, salivary glands, mammary glands, the respiratory system, the genito - urinary tract, and the gastrointestinal tract.Aims of the study Assessment of the salivary levels of heavy metals among the workers of Al - Daura oil refinery, assessment of the oxidative status in the oral cavity of the workers by measurement of Malondialdehyde and Superoxide dismutase markers,assessment of the oral immunological activity by measurement of secretory immunoglobulin A level in saliva and Assessment of the oral findings among the workers.Subjects, Materials and Methods This study was done in Al - Daura oil refinery, samples consist of 60 workers involved in refining processes as study group subdivided into three subgroups which represent the different sections in the refinery and 20 subjects not involved in refining processes as control group. Oral examination and saliva collection was done to assess the oral findings and measure the level of heavy metals (lead and cadmium), oxidative status (Malondialdehyde and Superoxide dismutase) and secretory IgA.Results The mean of salivary lead and cadmium was higher in study group (6.34 ?g/dl and 0.56 ?g/l respectively) than that of control group (3.3?g/dl and 0.34 ?g/l respectively) with highly significant difference (p

المستخلص: اجريت هذه الدراسة في فرع الفارماكولوجي في كلية الطب في الجامعة المستنصرية بالتعاون مع مركز ابحاث السرطان والوراثة\الجامعةالمستنصرية خلال الفترة من شهر كانون الثاني - شهراب لسنة 2014. الدراسة اقرت من قبل مجلس كلية الطب. صممت هذه الدراسة لتوضيح فعالية نبات ا | This study was conducted in the Department of Pharmacology at College of Medicine with incorporation of the Iraqi Center for Cancer and Medical Genetic Research at Al - Mustansiriya University, Baghdad, Iraq during 2014. This study was designed to elucidate the anti - cancer effect of Camellia sinensis by using four types of tea (black, green, white and oolong). Two experimental cancer models applied in this study; cancer cell lines (In vitro) and mice - bearing tumor (ex vivo). Several methodological and extracted aqueous and organic solvents were used to extract the tea. Microwave assisted extraction using distilled water as a solvent is applied in this study as the yield of bioactive substances are higher than other methods and organic solvents. The antioxidant activity was evaluated through the quantification of total flavonoids, total polyphenolic compound (bioflavanoids), total flavonols, reducing power, and proanthocyanidines. The scavenging property against reactive nitrogen species also was studied. The result showed that the different tea types contain approximately the same quantity of phenolic compounds; the only significant difference was in the proanthocyanidins level, which is a class of flavanols, found in high quantity in green tea compared with other tea extracts. Moreover, a significant scavenging property of peroxynitrite radical observed with all tea extracts. The extracts of black, green and oolong tea prevented or halted nitric oxide generation whereas the white extract tea promoted its generation, that is, a nitric oxide donor. The in vitro cytotoxic activity of Camellia sinensis in form of black, green, white and oolong tea was evaluated against four different types of cell lines. These are the AMN3 mammary cell carcinoma, Rhabdomyosarcoma, HeLa cells and Rat embryo fibroblast cells). The results showed greater effect of green and black tea over white tea and oolong tea against mammary cell carcinoma while the results of rhabdomyosarcoma cell line, which is an aggressive cancer cell, revealed a significant inhibitory effect of the growth of these cells by white and oolong tea extracts. All four types show almost equal percent of growth inhibition on HeLa cell line with the white tea been the most significant. A significant inhibitory effect of all tea extracts against the growth of rat embryo fibroblast cells indicated that the cytotoxic effect of the Camellia sinensis extended to normal cells and not specific to cancer cell. In addition, the antitumor effect of tea extracts was investigated (ex vivo) on BALB - c mice bearing - tumor. The volume, shape and color of the tumor masses were examined, in addition to measurement of the tissue malondialdehyde level as a biomarker of the lipid peroxidation, total tumor protein measurement and a histopathological study were done. The white tea showed antitumor effect by attenuating all the biomarkers of tumorogenesis. Herbal tea extracts induced DNA damage in term of separation the double strands molecule of calf thymus double stands DNA and human genomic DNA which may partly explained anti - cancer effect. We concluded that white tea extract is a promising nutrient that ameliorates the histopathological changes in mice bearing mammary tumor via generation reactive oxygen species by the evidence of activation lipid peroxidation process. Camellia sinensis plant can induce non harmful effect on DNA

المستخلص: Numerous interventional cardiovascular disease outcome studies have resulted in statins being an essential factor of cardiovascular primary and secondary prevention strategies.In recent years there was ahigh concern that statin use is associated with diabetes new onset which is strong, independent risk factor for cardiovascular (CV) and cerebrovascular outcomes ,several studies resulted in conflicting results regarding different statin types & dose effect on glycemic control. Atorvastatin which is the most widely used statin worldwide and rosuvastatin the most efficacious ;they have different structural characteristics that have been speculated to have influence on diabetes onset.Aim of the study : The present study aims at investigating the effect of different doses of atorvastatin and rosuvastatin on glycaemic indices and metabolic disorders on mice model of diet induced obesity. Materials and method : The animals were divided into two groups : one served as control that received normal regular chow & the other group received high fat diet for the whole 12 weeks of experiment.After eight weeks of HFD feeding ;group (2) farther subdivided into five groups(12 mice in each) ; the first group received HFD only ,the second group received single daily dose / po of 20mg /kg rosuvastatin ,the third group received single daily dose / po of 40mg /kg rosuvastatin ,the fourth group received single daily dose / po of 20mg /kg atorvastatin ,and the fifth group received single daily dose / po of 40mg /kg atorvastatin for the last four weeks of experiment.Body weight ,food intake, lipid profile ,glycaemic indices were taken at baseline ,before treatment and after treatment.At the end of experiment ,animals were sacrificed , plasma & tissue sample were collected for biochemical analysis and histological observations.Results : Results of the present study shows that high fat diet feeding resulted in obesity development and metabolic abnormality like; hyperglycemia ,hyperinsulinemia ,insulin resistance , dyslipidemia and moderate to severe hepatic steatohepetitis compared to control group. and treatment resulted in significant improvement in lipid profile ,reduction in food intake ,body weight ,also associated with improvement in insulin sensitivity , hepatic steatohepetitis and reduction in insulin secretion.twenty mg/kg dose of atorvastatin showed better influence on glycaemic indices and comparable influence on hepatic picture over fourty mg/kg does while twenty mg/kg dose of rosuvastatin resulted in deterioration of glycaemic indices and no apparent improvement in hepatic steatosis. Unlike group that received 40 mg /kg rosuvastatin which showed significant improvement in all related metabolic disorders. Conclusion : Feeding mice with high calories diet for 2 month result in induction of obesity and disturbance of metabolic parameters. Treatment with rosuvastatin or atorvastatin has good impact on bodyweight , metabolic derangements &hepatic steatosis in obese mice. Both drugs seems to improve lipid profile in dose dependent manner, however their effects on glycaemic indices has different attitude. It is seems that rosuvastatin, especially at high dose, has better impact on glycaemic indices than atorvastatin and this might attributed to the difference in their pharmacokinetic properties

المستخلص: (Diabetes Mellitus) D.M : - is the most common endocrine disease, characterized by abnormalities of glucose, protein and lipid metabolism. Diabetic neuropathy is one of the long term chronic complications, which contributes to increase the morbidity & mortality rate in diabetes. One of the earliest manifestations of diabetic autonomic neuropathy is denervation of the cardiovascular system, assessment of cardiovascular reflexes affords a satisfactory evaluation. Along duration time.A battery of bedside clinical tests was used to assess the autonomic function of the heart. This is the response of blood pressure to sustained handgrip and standing - up. The R - R interval change and Q - T interval change in the E, C G in response to standing - up, deep breathing and valsalva maneuver. Number of the patients was 40 diabetic subject and 22 age and sex matched healthy controls. Insulin dependent diabetes Mellitus (IDDM) was 25(62.50%) of cases, non insulin dependent Diabetes Mellitus (NIDDM) was 15(37.5%) of cases, autonomic neuropathy was detected in 23 patients (57.5%), Orthostatic hypertension in 19 cases (47.5 %), abnormal blood pressure response to sustained hand grip in 20 (50%), abnormal valsalva ratio in 10 (25%), abnormal heart rate response to deep breathing in 11 cases (27.2%).Among the 13 patients with cardiac diabetic autonomic neuropathy, had a Q - Tc interval of > 440 ms ( p < 0.05 ). Compared to the remaining 4 patients had normal Q - Tc interval of 399.5 ± 37.49ms.Cardiovascular tests for cardiac autonomic neuropathy showed increase prevalence with increase in the duration of Diabetes Mellitus above 15 years.This study showed that diabetics had significantly impaired cardio - autonomic reflexes compared to non diabetics. Also, other group of diabetics who have apparently normal cardio - autonomic reflexes were found to have significantly different values compared to the control group, (heart rate variations with deep breathing and valsalva maneuver had a negative correlation with age)

المستخلص: الخلفية : داء السكري يشير الى مجموعة من امراض الايض مع ارتفاع مستوى سكر الدم. يمثل النوع الثاني من داء السكري ما نسبته 90 - 95% من جميع حالات السكري. يمثل النقص في الانسولين ومقاومة الانسولين وغيرها من الاضطرابات الهرمونية المشاكل الاساسية لمرضى السكري من ال | Background : Diabetes mellitus (DM) describes chronic metabolic disorders with hyperglycemia. Type II DM (T2DM) represents for approximately 90 - 95% of all diabetic types. A combination of insulin deficiency, insulin resistance and other hormonal irregularities are key problems with T2DM. Adipose tissue can be classified into two types : the brown and white adipose tissues. The white type is considered an important secretory organ which produces many bioactive molecules, collectively termed adipokines. Recently, a new adipokine named omentin - 1, has been identified and it was found that individuals with impairment in glucose homeostasis and newly diagnosed T2DM showed a lower serum omentin - 1 level. However, the effects of antidiabetes drugs on serum omentin - 1 level had not been studied extensively.Objective : The current study was design to measure serum omentin - 1 in T2DM as comparing with control subjects, also to study the effect of three months therapy with metformin and/or sitagliptin (when added to ongoing metformin therapy) on serum omentin - 1 levels in addition to other parameters.Method : This study was carried out on thirty healthy control subjects, and sixty three T2DM patients. The patients enrolled in the current study were divided into two groups. First group : included thirty one of newly diagnosed T2DM patients, started treatment with metformin. Second group : included thirty two patients with T2DM, already on ongoing metformin therapy and started treatment with sitagliptin. All patients received their treatment for three months duration, and blood samples were collected from them at the beginning of the study and after three months of starting treatment to measure the possible change in the studied parameters which include : fasting blood glucose (FBG), postprandial blood glucose (PBG), Glycosylated haemoglobin (HbA1c), serum level of insulin, insulin resistance (IR), serum omentin - 1 levels, lipid profile, body mass index (BMI) as well as blood pressure. Results : The results showed that baseline level of serum omentin - 1 in the newly diagnosed T2DM was significantly lower than matched control subjects. The level of omentin - 1 was significantly reduced after three months duration of treatment in sitagliptin group with no significant change in metformin group. FBG, HbA1c and PBG were decreased significantly after three months in metformin group, while in sitagliptin group, only HbA1c and PBG were decreased significantly after three months. In both groups, and after three months duration of treatment, there were no significant changes in serum level of insulin, IR, TG, VLDL - C, HDL - C, BMI, and blood pressure.Conclusion : In newly diagnosed patients with T2DM, serum omentin - 1 was reduced compared to age and BMI matched healthy subjects. Three months treatment with sitagliptin resulted in a significant reduction in omentin - 1 levels compared with baseline values. However, three months treatment with metformin had no significant effect on serum omentin - 1 level compared with pre - treatment value

It is well known that pediatrics age groups are at higher risk for sedation - related complications than adults. Auditory brainstem response testing is one of the important diagnostic procedure that usually need sedation in order to preformed in children. Chloral hydrate is a hypnotic agent used since 1832 with low incidence of adverse events; whoever, despite the world wide use it is being abandoned due to bitter test, long time of sedation onset, vomiting and mild sedation. Rectally diazepam, on the other hand, produces higher and fast concentration in CSF with greater rate of success but probably with higher adverse events. Aim of the study : were to compare the sedative effect of chloral hydrate with chloral hydrate diazepam combination as well as their related adverse effects in children underwentg auditory brainstem response testing. Methods : in this randomized clinical study, 160 child underwent sedation for auditory brainstem response test participated. They were divided equally and randomly into 4 groups. Group A : Received 20 mg/Kg oral chloral hydrate as sedative, Group B : Received 20 mg/Kg oral chloral hydrate plus 0.5 mg/Kg diazepam rectally, Group C : Received 40 mg/Kg oral chloral hydrate as sedative, and Group D : Received 40 mg/Kg oral chloral hydrate plus 0.5 mg/Kg diazepam rectally. At the beginning, blood pressure, respiratory rates, peripheral oxygen saturation recorded, and then re - recorded immediately after drug administration and at (3, 5, 10, 20, …. min). Ramsay sedation scale used for assessment of the sedation level which measured every 10 min. Results : This study shown the beneficial use of chloral hydrate in combination with diazepam as sedation in ABR test (in groups D) by increased in the sedated number (p<0.05), decreased in the requirement of chloral hydrate re - dose, increased in the number of children whom completed ABR test (p<0.05) without significant differences on side effects or vital signs compared with the others three groups. 4.3. Conclusion : From this study we concluded that : • Used of oral chloral hydrate in dose (20mg/kg) alone not sufficient as sedative in paediatrics for ABR test.• Used of oral chloral hydrate dose (20mg/kg) in combination with rectal diazepam (0.5 mg/kg) better than used it alone as sedative in paediatrics for ABR test.• Used of oral chloral hydrate dose (40mg/kg) in combination with rectal diazepam (0.5 mg/kg) was the best sedative in paediatrics for ABR test. • Used of Chloral hydrate diazepam combination in ABR test of paediatrics increased the number of the sedated children, decreased the requirement of chloral hydrate re - dose, and increased the number of completed ABR test, with less complication

Therefore this study includes the evaluation of the immune status in sera of Babylon governorate displaced and residents with specific aspect for isolation and identification of measles virus from suspected cases. The immune response was evaluated by means of ELISA test (enzyme linked immunosorbet assay) for titration of IgM and IgG immunoglobulin level, in addition to evaluation of perforin level in the sera of 90 measles vaccinated individuals included in this study (50 displaced and 40 residents) from different areas in Babylon governorate, that were collected during the period extent from January up to April of 2016. Data about individuals were fixed according to information of formula including age, sex, geographical location, place displace of displaced and the vaccination date. Successful virus isolation from suspected cases on two types of cells culture included Vero cells line and chicken embryo fibroblast was carried. The titer of the isolated virus on Vero cell line reached (105.8 TCID50 / 0.1ml),which was higher than the titer of the virus isolated on CEF which reach (105.4 TCID50 / 0.1ml) after the third passage of the virus. The isolated virus was confirmed by indirect immunofluorescence technique.The age of subjects included in this study ranged from <1 year up to 24 years old. The results revealed that 15 (30%) have positive IgM index in sera of displaced, whereas residents sera sample shown only 6 (15%) positivity. Howover, all 90 (100%) subjects of both groups showed positive IgG index. The results of the present study showed that there were no significant difference of perforin level in sera of refugees and residents at p<0.05.Assaying of immune response against measles virus by measuring IgM immunoglobulin in sera of vaccinated displaced and resident with measles vaccine reflected a highly significant difference between two groups which reached 0.43 mIU/ml in sera of displaced in comparison with residents sera which reached 0.34 mIU/ml. The result showed also high significant differences in IgM between females and males. The females sera IgM levels of displaced and residents were higher than its level in males sera which reached 0.47 mIU/ml and 0.35 mIU/ml, respectively, in comparison with male sera level which reached 0.40 mIU/ml and 0.32 mIU/ml, respectively. According to age group, the highest IgM value was recorded in displaced and residents sera in age group 10 - 14years (0.50 mIU/ml) and 5 - 9years (0.36 mIU/ml) respec - tively. Whereas the lowest IgM serum value was detected in age group <1 year (0.34 mIU/ml) and 15 - 19years (0.31 mIU/ml) for displaced and residents subjects. According to geographical location, the highest IgM level was detected in sera of displaced from Tal Afar city (0.44 mIU/ml) followed by displaced from Ramadi (0.41 mIU/ml) and the lowest IgM value was detected in sera of displaced from Mosul city (0.33 mIU/ml). Whereas the highest IgM value in sera of residents in the subjects of Al - Mahaweel city (0.37 mIU/ml) followed by subjects of Hilla and Al - Qasem city (0.29 mIU/ml and 0.28 mIU/ml) respectively. For IgG serum immunoglobulin the results revealed that there was no difference in significant levels in both group population. But according to age groups significant difference between displaced and residents was detected at p <0.05 in which the 1 - 4 years old showed the highest IgG serum level in both group (1.98 mIU/ml and 2.18 mIU/ml) respectively. While the lowest IgG sera value was recorded in displaced age group of < 1 year old (0.60 mIU/ml) compared with residents age group of 20 - 24 years old (1.65 mIU/ml).It could be concluded that the results showed that the displaced do not have any effect on the residents of the province of Babylon for measles as a result of the good immunization by Babil Health directorate following to the Ministry of Health.

So considering the impact of anti - diabetic drug on omentin - 1 levels may provide adjuvant strategy to protect diabetic patients against clinical hazards.Aim of the study : The present study aimed to investigate the influence of treatment with metformin alone or in combination with gliclazide on the level of serum omentin - 1, in addition to the other biomarkers adopted in the study in order to evaluate whether the combined therapy (metformin plus gliclazide) ameliorate or adversely effects on some cardiac protector markers of metformin among recently diagnosed patients with type 2 diabetes mellitus.Methods : A total number of 100 recently diagnosed patients with type 2 diabetes mellitus were enrolled in the present study from December 2014 until June 2015. Sixty eight patients completed the 12 weeks course of treatment; divided into two equal groups based on treatment regimen in which group1 treated with metformin and group2 treated with metformin plus gliclazide. Thirty two patients did not complete the course of the treatment for unknown reasons and considered as default. In addition to 31 healthy volunteers were randomly chosen and considered as Control Group. In which all the participants in the study underwent detection of blood pressure, pulse rate, weight, height & BMI in addition to the estimation of the levels of others biochemical analysis as glycemic indices, lipid profile & serum omentin - 1at the beginning of the study & after 12 weeks of treatment regimen.Results : The results of this study shown the beneficial amelioration of metformin on some markers that affect CVS represented as significant reduction in BMI (p<0.05), modest improvement in lipid profile with modest elevation in HDL level & lowering blood pressure, significant reduction in the levels of blood glucose & HbA1C (p<0.05), improves insulin sensitivity, reduced insulin resistance, and elevation of serum omentin - 1 level among newly diagnosed type 2 diabetic patients (group1). Furthermore, the results of current study are revealed that adding of gliclazide to metformin in treatment of type 2 diabetic patients might influence the documented beneficial effects of metformin on cardiovascular system at least by adversely changing the levels of serum omentin - 1 among group 2. Conclusions : Adding of gliclazide to metformin in treatment of patients with type 2 DM might extend the therapeutic action of metformin in regarding much better controlling of glycemic indices, insulin sensitivity and lipid profile. But, at the same time, it might attenuate some of beneficial effects of metformin on cardiovascular system at least by adversely influence on body weight and serum omentin - 1 levels.

المستخلص: في ستينيات القرن الماضي كان هناك نوع من العلاجات تستخدم للسيطرة على وزن الجسم او لتخفيفه , تلك المواد تعمل على تثبيط عضيات المايتوكوندريا من انتاج الطاقة وتحويل مجرى تفاعلات الاكسدة نحو انتاج الحرارة بدلا عن الطاقة وبذلك تحفز من زيادة اكسدة الشحوم ومادة ا | Background : Obesity is a state of excessive accumulation of fat tissue in the body , increasing energy expenditure is good way to manage obesity and the related complications. Mitochondrial uncouplers increase energy expenditure , they used before for weight controlling programs because these compounds uncouple mitochondria from generating ATP , moreover stimulate lipid and glucose oxidation preventing lipid accumulation in excess caloric intake conditions specially. Niclosamide an old drug introduced in 1960s as anthelmintic and had FDA approval for the treatment of most of tapeworm infections. It is well known mitochondrial uncoupler.Aim of the study : The present study aimed to investigate the influence of trial of the use of niclosamide in comparison to effect of metformin and their combination on body weight , glycemic indices and lipid profile in high fat diet induced obese mice.Materials and methods : The animals firstly divided to two groups one fed with normal regular mouse chow (30 mice) and the 2nd fed with high fat diet (60%kcal) for 2.5 months(100 mice) 10 mice from each group sacrificed at beginning of study represent baseline values and another 10 mice from each group sacrificed after 2.5 months to assess effect of high fat diet on study parameters. The group that fed with high fat diet further subdivided to 4 groups after 2.5 month of high fat diet feeding each 20 mice , 10 mice from each group sacrificed before treatment represent pretreatment values. Before treatment there are 5 groups assigned as group 1 fed normal regular mouse chow till the end of study , group 2 fed high fat diet without treatment till the end of study , group 3 fed with high fat diet till the end of study and treated with niclosamide for one month (150mg/kg) after obesity induction by high fat diet , group 4 fed with high fat diet till the end and treated by metformin (300mg/kg) for one month and finally group 5 fed with high fat diet till the end of study and treated by combination of niclosamide and metformin (150mg/kg , 300mg/kg respectively). blood samples taken from tail vein to evaluate the study parameters at baseline and after obesity induction by high fat diet (after 2.5 months) and after treatment ,then animals were sacrificed and livers were taken for histopathological observations.Results : The results of this study shown that the animals fed with high fat diet show metabolic disturbances manifested by significant increase (P < 0.05) in body weight , fasting insulin & fasting plasma glucose. Lipid profile show significant changes (P < 0.05)(cholesterol , triglycerides ,low density lipoproteins increased while high density lipoproteins decreased ) as compared to control group. High fat diet group also show impaired glucose tolerance , impaired insulin sensitivity and obvious liver structural changes manifested by sever steatosis.Treatment with niclosamide show improvement in all metabolic disturbances induced by obesity ; body Weight , fasting insulin and fasting plasma glucose reduced significantly (P < 0.05). Lipid profile parameters improved ; cholesterol , triglycerides , low density lipoproteins reduced significantly (P < 0.05) by one month treatment with niclosamide and high density lipoproteins increased significantly (P < 0.05) as compared to their baseline values before treatment, Glucose and insulin tolerance improved. It is nice to mention the influence of niclosamide in this study was comparable to metformin in all evaluated parameters.Combination of both drugs show favorable improvement in metabolic disturbances induced by obesity rather than each drug when used alone specially on liver histopathological changes.Combination of both drugs show significant reduction (P < 0.05) in body weight ,fasting plasma glucose and fasting plasma insulin. Lipid profile parameters improved significantly (P < 0.05) , glucose and insulin tolerance improved.Liver histopathological changes ameliorated to higher extent and become the closet to normal liver tissue morphology.Conclusions : The result suggest niclosamide have good antidiabetic action and can ameliorate the metabolic changes induced by obesity significantly. Its action is comparable to that of well known antidiabetic drug metformin. Niclosamide has favorable effect on body weight and can reduce body weight. Its combination with metformin show better improvement in metabolic disturbances induced by obesity and it has very good hepatoprotective effect against liver histopathological changes induced by high fat diet.

المستخلص: The circulating peptide hepcidin is secreted mainly by the liver as an 84 - amino acid precursor that is subsequently processed and secreted as a 25 - amino acid peptide form. It is considered the "master regulator" of iron metabolism.Transferrin receptor is a carrier protein for transferrin. It is needed for the import of iron into the cell and is regulated in response to intracellular iron concentration. It imports iron by internalizing the transferrin - iron complex through receptor - mediated endocytosis. This study addresses the physiological role of hepcidin in vivo and investigates the role of hepcidin as an erythroid regulator, contributing to the modulation of iron absorption by the intestine and iron release by the macrophages in the situation of anemia with normal or increased iron stores. Measuring the transferrin receptor level and it's relation to hepcidin is another part of the data involved in this study.Methods : This study included 64 Iraqi patients, 34 of them have iron deficiency anemia and the other 30 are iron overload patients. They attended the National Center of Hematology and Thalassemia center in Al - Karama Teaching Hospital during the period from October 2014 until April 2015 together with 30 healthy controls. Information regarding age, sex and clinical presentation were recorded. ELISA technique used to measure hepcidin and transferrin receptors level in patients and healthy control groups.Results : ? Mean serum hepcidin level in iron deficiency anemia patients was (205.3ng/ml) while in iron overload patients was (6.7ng/ml).? Mean serum level of transferrin receptors in iron deficiency anemia was (11006.3ng/ml) and in iron overload was (604.5ng/ml).Conclusion : ? The mean level of serum hepcidin in thirty iron deficiency anemia patients is high. Its elevation represented an acute phase response. While in thirty patients with iron overload, hepcidin mean level was low mainly due to stress erythropoiesis.? The current study result addresses the usefulness of soluble transferrin receptor for assessing high iron status in population and how soluble transferrin receptor is useful in the evaluation of anemic patients.

المستخلص: تعتبر الاحصائيات الصحية الرصينة ضرورة لاتخاذ القرارات السليمة في كل مستويات النظام الصحي. ولكن في الحقيقة ان نظم المعلومات الصحية في معظم البلدان تعتبر غير كافية لتوفير المعلومات اللا زمة لدعم الادارة الصحية ولهذا فان معظم النظم الحالية تعتبر كعائق اداري | Sound health statistics are essential for health decision - making at all levels of the health system. Unfortunately, health information systems in most countries are inadequate in providing the needed management support and the current systems are therefore widely seen as management obstacles rather than as tools, the current study is an attempt to assess the health information system in Iraq with recognizing the strengths, weaknesses and gaps in addition to assessment of the structure and performance of this system; it also attempts to assess the behavioral, technical and organizational determinants affecting the health information system performance. A cross - sectional study was conducted for the assessment process and the levels of the assessment included the ministry of health (national level), the health directorates (provincial level), the districts related to the health directorates reaching to the health centers level, as well as the hospitals related to the health directorates, in addition to the ministry of planning and the ministry of interior. In addition to ministry of health (central level) a total of six governorates were selected by simple random sampling including the capital Baghdad with a seven districts were selected from those governorates also by simple random sampling and a total of twenty six health centers were selected from those districts, as well a total of seven hospitals were included in the study from all governorate and they were selected according to convenience. The interview has been done by using the health metrics network assessment tool version 4, in addition to a complementary assessment tools which are the PRISM package tools that were used at the district and primary health center levels. Based on the data collected and according to the health metric network assessment tool findings the overall health information system has laid in the adequate state (65.96%) with most of its comprising components function poorly. Data dissemination and use and data management categories were the weakest with a score of 50% and 53.3% respectively, while for the resources category it was found to be adequate 63.3%, and for that of HIS indicators, data sources and information product categories they were 73.3%, 66% and 69.6% respectively. For that of the PRISM tools and the findings obtained by them from the collected data the results revealed that a low data quality in term of accuracy with 29.03% at the facility level and 55.35% at the district level, while the completeness rate was excellent with a score 96.38% at the facility level and 98.23% at the district level, for that of the timeliness it was 70.43% timeliness at the district level. The information use for a given feedback at the facility was 50% and at the district was 82.12% and for observed meeting records it was 50% for the facility and 41.6% for the district level. For that of the functionality a 34.61and 67.30% of the facilities reported having a reminder mechanism for data completeness process and meeting a deadline for submitting monthly reports respectively, Data analysis was better at the district 85.71% than at the facility 81.7%, Data display were present in all of the facilities and districts. For the technical determinant the results showed 57%, 85.7%, 71.4% and 100% of the district respondents felt that the form is complex and difficult to follow, data software is a user - friendly, information technology is easy to manage and a comprehensive picture of the health system performance is captured by the system respectively,85.7% believed that the information system collecting information from some vertical programs and one district reported of no collection at all, in addition to that 100% reported the absence of a software that integrates data from different information systems and the available information technology doesn&#39;t provide full access procedure to district and senior managers. Regarding the behavioral determinants the results revealed that overall mean confidence for the information system tasks is 69.41% while for that of the task competence the overall mean competence level is 37.1%. Knowledge of checking data quality, knowledge of health information system rationale and problem solving showed results of 35.32% 37.68% and 2.98% respectively, and that of motivation level was 43.4%. Organizational determinants results revealed that the management functions at facility and district levels were almost absent, while for the perceived promotion of a culture of information it showed a total score of 63.96% and rewarding for a good performance was 56.83%. The activities for promotion of a culture of information are a 25% at the facility level and 28.75% at the district level. And that of supervision quality at the facility were (72.80%). Availability of resources revealed that 100% of the facilities have two or more computers and calculators respectively while only 57.7% have an internet access. Access to the electricity and water supply is very high, No facility reported of running out in registers in the last 12 months. Finally, the current study shows the importance for the need of further attention to be drawn to HIS, in addition to that, increasing the awareness and well coordinated efforts that need to be done to overcome weaknesses and to provide a well functioning HIS enabling for evidence based decision making and action provision in the health system.

On other hand Ginseng is an herbal plant is known for its therapeutic medical importance, it's used for different purposes in medical fields, that is effective against many diseases, act as a tonic and provide energy with significant reduction in mental and physical fatigue.Aims of the study To evaluate the central effects of Panax Ginseng and/or citicoline on normal healthy volunteers.Material and Method The subjects are randomly divided into four groups for assessment of central effects of Panax Ginseng and /or citicoline compared with placebo. The evaluation of the central effects was done by using the Leeds psychomotor battery tester for evaluating the psychomotor performance, workshop test was used to evaluate working memory function.The enrolled volunteers were randomly divided into the following groups : First group regarded as control group that treated with 500 mg/day of starch capsule as a single dose, second group, received Panax Ginseng capsule 500 mg /day, a third group received citicoline capsule 500 mg/day and the fourth group received Panax Ginseng capsule 500 mg/day plus citicoline capsule 500 mg/day as a single dose. All participants are followed for two consecutive weeks from starting treatments.ResultsIn the present study the placebo didn't have any central effect and MDA serum levels were not significantly change. Panax Ginseng has statistically significant effect on the most parameters of the psychomotor performance, working memory performance, as well as reduction of MDA serum levels. On the other hand, citicoline has statistically a significant effects on most parameters of the psychomotor and working memory function with statistically significant reduction of MDA serum levels.The combination of Panax Ginseng and citicoline have a highly statistically significant effect on all psychomotor performance, working memory performance and statistically significant reduction in the oxidative stress marker (MDA). ConclusionResults of the present study showed that combined effects of citicoline plus Panax Ginseng on central function produced more statistically significant effects on psychomotor performances, CFFF and working memory function than either Panax Ginseng or citicoline when they used alone, in addition to the combined effects of citicoline plus Panax Ginseng have a more significant effect on the oxidative stress,during mental stress.

Health care evaluation in neonatal intensive care units of maternity wards in Baghdad hospitals in terms of input (human and non - human resources) and outcome.2. Identifying causes of admissions and causes of deaths occurring in neonatal intensive care units The study consisted of two parts : A structure evaluation is using a check list to assess availability of human and non - human resources, covering infrastructure, manpower, equipment, and supplies; and an outcome evaluation study using hospital registration records review for causes of admission and causes of death in neonatal intensive care units during the year 2013.It was found that the mean number of specialist doctors in neonatal intensive care units was 2.1 and with standard deviation ±1.3, and college nurse was 2.2, with standard deviation of ±4.004, pharmacist was 0.4 with standard deviation of± 0.516 and for supplementary staff 1.5 with standard deviation of± 0.516.More than half 54% of nurses had no training in neonatal care.Concerning the availability of general equipment it was adequate except for computers 40%.Air conditioning, lighting and windows in addition to safe water supply was good 100% but ventilation was poor 67%, hand washing area was not always present 60% and free elbow operated water tubes were available in 6.7%. Availability of neonatal intensive care units special area was adequate for storage area 85.7% gowning area78.6%, while all the remaining areas were poorly available (resting room, examining room, mother room, boiling and autoclave room, area for mixing intravenous fluid and medication).Neonatal intensive care units were narrow and area/incubator ranging from 2.28m2 to 4.36m2/ incubator. Number of incubators was 246 with patient/ incubator ratio 53.6 : 1 and 27% of Neonatal intensive care units had no regular maintenance for incubators. Large Neonatal intensive care units >25 incubators were overcrowded, having below standards area/incubator, incubators covers only two third of neonatal care. Still up to one third of Neonatal intensive care units are getting their oxygen supply by cylinders, not pipes. Most equipment for individual use were poorly available. Most of Neonatal intensive care units emergency (cupboard) drugs and supplies were sufficiently available round the clock. Total admissions to Neonatal intensive care units were 13195 neonates. Male neonate's admissions 60% were higher than females 40%. Main causes of admission were Respiratory distress syndrome 43%, prematurity and low birth weight 19.4%, and Transient tachypnea 17.4%; birth asphyxia 4%, and hypoglycemia 3.8%, Congenital anomalies 3.7%, Neonatal jaundice 3%, while meconium aspiration and septicemia were the lowest1%. From all these admissions 74% were discharged well, (6%) were referred, while those discharged against medical advice were (4%) and the rest (16%) died. The main causes of death in Neonatal intensive care units were Respiratory distress syndrome 34%, prematurity and low birth weight 31% congenital anomalies 12%, birth asphyxia 8%, septicemia 4%, meconium aspiration 1% and 10% due to other unclassified causes. From this evaluation study, it can be concluded that there were Neonatal intensive care units with under staffing, undertraining and poor designing. Respiratory distress syndrome and prematurity were the main neonatal health problems.

Aim of the study : The present study investigated the influence of pretreatment with rosuvastatin and telmisartan alone or in combination in different doses on doxorubicin induced acute cardiotoxicity in rats using biochemical and histological approaches. Materials and methods : The animals were divided into eight groups of 5 animals each. The first group received no drug(s) po but a single dose of distilled water (7.5 ml/kg, ip) on day eight, which serves as the control group. The second group received no drug(s) po but a single dose of doxorubicin (15 mg/kg, ip) on day eight, and serves as doxorubicin only received group. The third and sixth group received rosuvastatin (2 , 10) mg/kg/day respectively for nine successive days, and on day eight, one hour after drug administration, a single dose of doxorubicin (15 mg/kg, ip) was given. The fourth and seventh group received telmisartan (2 , 4) mg/kg/day respectively for nine successive days, and on day eight, one hour after drug administration, a single dose of doxorubicin (15 mg/kg, ip) was given. The fifth and eighth group received both drugs, where the fifth group received both of rosuvastatin (2 mg/kg, po) and telmisartan (2 mg/kg, po), 1 hour apart, daily for nine successive days, and on day eight, one hour after drug administration, a single dose of doxorubicin (15 mg/kg, ip) was given. While the eighth group received both of rosuvastatin (10 mg/kg, po) and telmisartan (4 mg/kg, po), 1 hour apart, daily for nine successive days, and on day eight, one hour after drug administration, a single dose of doxorubicin (15 mg/kg, ip) was given.At day ten of the study, blood samples were taken for biochemical analysis, then animals were sacrificed and hearts were taken for histopathological observations. Results : Rats treated with doxorubicin showed cardiotoxicity as evidenced by significant elevation of serum cardiac troponin (CTn - I) level, lactate dehydrogenase (LDH) activity, serum malondialdehyde (MDA) level, and interluekine 17 (IL - 17) level associated with important histopathological alterations while pre - treatment with rosuvastatin and telmisartan elicited a significant decrease in the activities of all markers measured in comparison with doxorubicin treated group with pronounced resolution of Dox induced cardiac histological changes to a milder picture.Conclusion : These results suggest pretreatment with rosuvastatin and telmisartan alone or in combination provide a significant protective effect against acute - doxorubicin induced cardiotoxicity in rats represented by biochemical markers and histological approaches.

المستخلص: تجارب الطفولة السيئة تشير الى اكثر مصادر الاجهاد شيوعا وشدة التي يعاني منها الاطفال في حياتهم المبكرة. من هذه الخبرات الاساءة، الاهمال، العنف بين الابوين او مقدمي الرعاية والعنف المجتمعي. وتبين ان الاجهاد الطويل في الطفولة له اثار طيلة الحياة على صحة | Adverse Childhood Experiences refer to some of the most intensive and frequently occurring sources of stress that children may suffer early in life. Such experiences include multiple types of abuse; neglect; violence between parents or caregivers and community violence exposure. It has been shown that prolonged stress in childhood has life - long consequences for a person's health and well - being; it may lead to serious problems such as alcoholism, depression, eating disorders, heart diseases, cancer, and other chronic diseases. Resilience is the ability to manage crises, difficult situations and developmental tasks. Research on resilience has identified several factors that strengthen the power and resources of children as well as promote their abilities to cope successfully with crises and internal and external problems. This cross - sectional study was conducted to estimate the effect of adverse childhood experiences and resilient factors on adults’ heath. It was done during the period from January 2013 through January 2014. The study sample was drawn from Baghdad City. Multistage sampling technique was used to choose 13 primary health care centers and eight colleges from three universities in Baghdad; the questionnaire was filled through a direct interview with the participants. In addition to that, teachers of seven primary schools and two secondary schools were chosen by a convenient method. A total of 1040 subjects were surveyed and 1000 responded. Their age ranged between 18 to 59 years (32.08±11.169). Females constituted a higher proportion (58.3%) of the study sample, 60% of this sample had university/diploma as the highest level of education. The results showed (during childhood) that seeing or hearing a parent or household member in home being yelled at, screamed at, sworn at, insulted or humiliated was reported in 469 (46.9%). A parent, guardian or other household member yelled, screamed or swear at, insulted or humiliated them was registered in 387 (38.7%). A parent, guardian or other household member spanked, slapped, kicked, punched the subjects was seen in 335 (33.5%). father's death (when the subject's age was 15 years or less) was reported in 104 (10.4%) of the participants, and 74.8 % of the subjects like to be the kind of people their parents were. The multiple linear regression models demonstrated that being in the fourth quartile (highest quartile) of household dysfunction - abuse score is expected to significantly increase depression symptoms score by a mean of (10.4) compared to subjects in the lowest (first quartile) of household dysfunction - abuse score, being in the fourth quartile of family bonding score is expected to significantly decrease depression symptoms score by a mean of ( - 22.5) compared to subjects in the first quartile, the same is correct for self - esteem score which increases by a mean of (21.484) for the fourth quartile of family bonding score compared to subjects with lowest (first quartile) after adjusting other explanatory variables. Logistic regression model showed that being in a higher level of family bonding (fourth quartile) is expected to reduce the risk of having chronic physical diseases by almost the half (odds ratio =0.57) and being exposed to a high level of household dysfunction and abuse (fourth quartile) is expected to increase the risk of having chronic physical diseases by 81%. A positive history of suicidal attempts showed a strong positive association with mean score of household dysfunction and abuse. Family bonding during childhood appears to be the most important resilient factor that protects adults against sedative or narcotic usage, mental disorders, suicide attempts, and chronic physical diseases during adulthood. Higher levels of exposure to adverse childhood experiences have a positive association with substances usage, suicide attempts, symptoms of mental disorders and chronic physical diseases in adulthood.

The statistics show that this disease in men is more prevalent than women and this type of leukemia is increasing with age. Objectives : To assess biochemical changes related to iron status in acute myeloid leukemia pre and post course of chemotherapy and evaluate a relationship between serum hepcidin and IL - 6 in patients with acute myeloid leukemia pre and post chemotherapy and compare their levels to controls and their contribution on the pathogenesis of AML.Patients, Materials and Methods : The present study conducted at the National Center of Hematology and Baghdad Teaching Hospital in the Medical City from February 2014 to June 2014.The study included Fifty - eight (58) patients (30 male and 28 female) diagnosed with acute myeloid leukemia the age of patients range (15 - 65 years). Forty three (43)patients continued the study (24 male and 19 female) divided into two groups : Group (1) Patients with AML before starting chemotherapy. Group (2) the patients after 4 weeks of chemotherapy. Patient's treatment was done according to international protocol used in acute myeloid leukemia and called (3+7) where Doxorubicin was given from the first day to third day and Cyatrabine (Ara - C) was given from the first day to seventh day.Evaluationwas done on day (28) from starting chemotherapy to assess response of patients through bone marrow aspiration.All patients were subjected to complete history and physical examination. Diagnosis of AML patients was established by complete blood count and blood film, bone morrow aspiration and biopsy, hepcidin, interlukine - 6, C - reactive protein, ferritin, iron, total iron binding capacity, alkaline phosphstase, direct bilirubin were done for all patients.Forty - three (43) healthy subjects (24 male and 19 female) were enrolled in the study mainly from medical staff and their families. They were age and sex matched to patients group and considered as controls as ( Group 3).Results : • Serum hipcidin levels were significantly higher in(AML)patients (Group 2) compared to newly diagnosed(Group 1) and to healthy subjects ( P<0.0001).• Serum (IL - 6) levels were higher but not significant in(Group 1) compared to (Group 2) and significantly with healthy controls(P<0.214 and P<0.0001 respectively).• A significant increase in mean of serum ferritin levels were observed in (Group 2) compared to newly diagnosed patients (Group 1)(P<0.002) and the levels were significantly higher in newly diagnosed group compared to healthy controls (P<0.015).• Patients with (AML) during remission show significant decrease in levels of iron compared to newly diagnosed group(P<0.0001),while levels in healthy controls was higher values than both (Group 2) and (Group 1) (P<0.0001).• Total iron binding capacity (TIBC ) levels showed a significant decrease in (Group 2) after treatment compared to (Group 1) before treatment(P<0.0001) but the levels were significantly higher in healthy controls compared to (Group 1) and (Group 2) (P<0.0001).• Mean serum ALP levels showed highly increase in (Group 2) patients when compared to patients before treatment (Group 1)( P<0.0001), but the difference is not significantly higher between the newly diagnosis and controls (P<0.687).• A significant increase in mean serum direct bilirubin levels were observed in (Group 2) patients when compared to (Group 1) and healthy controls(P<0.0001).• Regarded to CRP levels in AML patients before and after treatment, the CRP levels increased in AML patients after treatment than newly diagnosed AML patients.Conclusions : Hepcidin and Interlukin - 6 may be used asprognostic for acute myeloid leukemia and also can play an important role in pathogenesis of AML.

المستخلص: عجز لقلب المزمن : حالة تقويضية معقدة متمثلة بمرحلة تشخيصية متقدمة مدمرة ونهائية. ان عملية انتقال المرض من مستقر الى دنف القلب(اعتلال عام مع هزال) ليست مفهومة جيدا, وهناك عدد من العمليات المختلفة للحفاظ من عملية الهدر، وهي في معظمها حيث وجدت لتكون في وقت م | Chronic Heart Failure(CHF)is a complex catabolic state that carries a devastating prognosis. The transmission from stable disease to cardiac cachexia is not well understood. A number of different mechanism maintain the wasting process, most of which were found to be activated early in the development of CHF.Many of these pathways are initially activated to protect heart from damage and to compensate for impaired myocardial function. Mediators that have been implicated in this process include pro - inflammatory cytokines like interleukin 1 and 6, tumour necrosis factor - ? and the acute phase protein (C.R - P)these cytokines are activated during the course of CHF and maintaining the wasting process. Little is known about the mechanism leading to cardiac cachexia (C.C).Adiponectin and leptin are a protein hormones derived from adipocytes and they are important regulator of energy metabolism and body weight. Previous studies of CHF and C.C , had great differences between cachectic and non - cachectic patients.OBJECTIVETo study the relationship between Adiponectin, leptin & cytokines in cachectic &non cachectic HF patients & compared the results with coronary artery disease( CAD) patients with preserved left ventricular systolic function( LVSF) &healthy control to elucidate their roles in pathobiochemistary of cachexia, & to study the prognostic power of adiponectin in CHF, also to identify & confirm the role of proinflammatory cytokine(IL - 6& TNF - ?)& systemic inflammation marker (C - R.P)in the progression of CHF to cardiac cachexia.SUBJECTS &METHODE Studies were performed in Cardiology Clinics in Ibn Al - Betar hospital for cardiac surgery. Eighty eight subjects were divided into four groups each contain 22 subjects are enrolled in this study : 1st group : patient with HF(reduce LVSF)with cachexia include 5 females &17 males with age range from 47 - 76 years;2nd group : patients with HF(reduce LVSF)but without cachexia include 6 females& 16 males with age range from 34 - 70 years;3rd group : patients with CAD (preserved LVSF)include 11 males &11 females with age range from35 - 80 years & 4th group : consisted of healthy controls include 11male s& 11 females with age range from 36 - 65 years. The hormonal assay was done by ELISA.RESULTSPatients with CHF with cachexia had significantly higher concentrations of adiponectin than all other groups(p=0.004) ,that are associated with significant decrease in serum level of leptin(p=0.002), significant increase in serum level of IL - 6 when compared to other groups (p=0.0001)& significant increase in number of C - R.P positive compared only to healthy control(p=0.007),but serum level of TNF - ? is significantly decrease when compared to both CAD(p=0.023) &healthy control (p=0.0001)although it was non - significant decrease when comper to patient with CHF without cachexia.In the patient with CHF without cachexia, non - significant increase in serum level of adiponectin (when compared to patient with CAD with preserved LVSF& non - significant decrease compare to healthy control), while serum level of leptin was non - significantly decrease (when compared to patient with CAD with preserved LVSF & non - significant increase when compared to healthy control) associated with non - significant decrease in serum level of TNF - ? in comparison to CAD with preserved LVSF but significant decrease compared healthy control(p=0.011)while serum level of IL - 6 significantly increase in comparison to both CAD with preserved LVSF(p=0.01) &healthy control(p=0.008).In CAD with preserved LVSF non - significant decrease in serum level of adiponectin,while non - significant increase in serum level of both leptin , IL - 6 & TNF - ? when compared to healthy control. In this study there is strong significant positive correlation between adiponectin & TNF - ? in patients with CAD with preserved LVSF(r=0.615,p=0.002); while adiponectin was positively correlated with E.F% in patients with CAD with preserved LVSF(r=0.448,p=0.037).Finally there is significant positive correlation between TNF - ? & IL - 6 in patients with CHF with cachexia(r=0.466,p=0.029).CONCLUSIONCachexia, is a catabolic state of CHF associated with increase in serum adiponectin concentration, this may be consider as preservation of physical response to the changes in body fat but might also suggest that adiponectin plays a role in pathogenesis of cachexia, while cachexia associated with HF is not caused by enhance leptin release but, by increased level of adiponectin which is powerful predictor of cardiac cachexia.Cardiovascular Disease(CVD) is associated with elevated marker of systemic inflammation)C - R.P(that plays important role in disease progression& increase level of proinflamnmatory cytokine)IL - 6(has been reported as important pathogenic factor contributed to cardiac injury during CHF& progression to cardiac cachexia, although ,the level of TNF - ? is lower & has no relation to the degree of cachexia

المستخلص: الفصا العظمي العقدي هو واحد من انواع التهاب المفاصل الموضعي. هو مرض المفصل التنكسي او الانحلالي, ويشمل الغضروف المفصلي والعظم تحت الغضروف, وهو يعتبر نوع من انواع امراض المناعة الذاتية. السبب الرئيسي للفصال العظمي العقدي غير معروف لكن هناك اسباب متنوعة مثل | Nodal osteoarthritis (NOA) is one type of the localised osteoarthritis that mostly occurs with postmenopausal women. It is degenerative joint disease, including articular cartilage and subchondral bone, it consider type of autoimmune diseases. The main cause of NOA is unknown but there are variety of causes like hereditary and metabolic, may initiate processes leading to loss of cartilage. The cartilage loss process usually lead to induce the immune system to release many of immune factors like cytokines , these factors lead to generation of immune response and inflammation in the joint. The NOA mostly occurs with postmenopausal women. It affects the smaller joint. Over several years, firm knobbly swellings form on the finger joints. These are caused by osteophytes so lead to bony enlargement and are known as Heberden's nodes when they are at the end joints of fingers (distal interphalangeal joints) or Bouchard's nodes when they are at the mid - finger joints (proximal interphalangeal joints). Once the nodes are fully formed, and not necessarily painful, they do limit the movement of the fingers significantly. NOA leads to the formation of bunions, rendering them red or swollen. Some people notice these physical changes before they experience any pain, but in advance cases, many of Symptoms may include like joint pain, stiffness and sometimes an effusion. When bone surfaces become less well protected by cartilage, bone may be exposed and damaged. As a result of decreased movement secondary to pain, regional muscles may atrophy, and ligaments may become more lax.Many studies have been done about inflammatory and biochemical markers in NOA and they found conflicting results. Objective1 - To evaluate serum adiponectin , interleukin - 6 (IL - 6) , anti cyclic citrullinated peptide (ACCP) and bone mineral density (BMD) in NOA.2 - To asses the CRP , RF and ESR in NOA.3 - To asses effect of age , gender , effect of BMI , smoking habit and duration of disease in NOA.Material and Method This study performed during the period from November 2013 to February 2014. These subjects were selected from patients attending the Rheumatology & Rehabilitation Consultation Unit at Al - Yarmouk Teaching Hospital. Patients and controls with hypertension, diabetes mellitus, malignancy, chronic disease of kidney, liver and any patients taken drugs that might effect the results have been excluded from the study.The laboratory tests were done in Al - Yarmouk teaching hospital laboratories and the laboratory research unit in collage of medicine / department of medical biochemistry. Subjects80 subjects (60 patients & 20 healthy controls) were enrolled in this study : A. First group : Patients with Nodal Osteoarthritis (NOA), No. = 60 (female =49 & male =11), rang of age (40 - 88) years.B. Second group : Healthy control group who had no history or clinical evidence of NOA or any other chronic disease like hypertension, DM and other chronic disease that might effect on the study data, No. 20 (female = 15 & male =5 ), rang of age (48 - 82) years.The patients were diagnosed as NOA according to the 2013 American College of Rheumatology (ACR) criteria, also the patients were diagnosed as normal, osteopenia and osteoporosis according to the 2013 American College of Rheumatology (ACR) criteria by measured of BMD (T - score) Normal : T - score (more than or equal - 1), Osteopenia : T - score ( - 1.1 - - 2.5) and Osteoporosis : T - score (less than - 2.5). The patients BMI were measured and determined as Normal (18 - 24.9 kg/m2), Over weight (24.9 - 29.9 Kg/m2), Obese grade - I (29.9 - 34.9 kg/m2) and Obese grade - II (more than 34.9 kg/m2) according to WHO 2012.MethodsELISA technique was used for the determination of serum adiponectin, IL - 6 and ACCP. Measurement of serum uric acid was done by spectrophotometric instrument. qualitative serological tests were used for determination of the CRP and RF also ESR determination were done in hospital laboratory. The BMI was determined by WHO equation's (2012) (weight/ (length) 2), also the BMD was determined by DXA scan according to ACR limits.Results obtained were subjected to statistical analysis by using SPSS and Excel program.ResultsLevels of serum adiponectin, IL - 6, CRP, ESR and BMI were significantly increased in NOA patients most than healthy controls, also the BMD (T - score) significantly decreased in NOA patients than healthy controls. But the age, gender, serum ACCP and uric acid were not significantly changed in NOA patients compared with healthy controls. Study of age, gende , BMI and duration of disease, found that they did not effect any parameters studied in NOA patients, only serum ACCP level was found to be significantly increased in females than males. Serum adiponectin level and CRP were significantly increased more in osteoporosis than osteopenia and normal. CRP was significantly increased in smoker than non smoker NOA patients.This study showed negative correlation between serum adiponectin and BMD, positive correlation between serum adiponectin and ESR, serum adiponctin and IL - 6 and IL - 6 and ESR in NOA patients. This study illustrated change in the status of the inflammatory markers like adiponectin, IL - 6 and other parameters in NOA disease. It illustrated effect of some of the factors like age, gender, BMI, BMD, smoking habit and duration of disease on development of NOA disease and on the status of the parameters studied. Also this study illustrated some correlation between the parameters in NOA patients.

المستخلص: Acute coronary syndrome (ACS) is an insufficient supply of the myocardium with oxygenated blood in which atherosclerosis is an essential cause of myocardial ischemia. Adipokine biomarkers plays an essential role in the atherosclerosis and hence coronary artery disease. Serum Vaspin, Omentin - 1 and troponin I Fast are the biomarkers that believed to be independently associated with acute coronary syndrome.Objective : The study was carried out to evaluate : serum Vaspin,Omentin - 1 and Troponin I Fast in patients with acute coronary syndrome [ST - Elevation Myocardial Infarction(STEMI), Non - ST - segment Elevation Myocardial Infarction (NSTEMI),and Unstable Angina pectoris (UA)], that may help in guiding the diagnosis and treatment.Subjects, Materials and Methods : The study include a total (100) individuals; (75) patients with acute coronary syndrome (ACS) and (25) healthy control.A total number of 75 patients with acute coronary syndrome (ACS) (50 male ,25 female ) as : 25 patients with STEMI (22 male and 3 female) 25 patients NSTEMI(16 male and 9 female ) and 25 patients with unstable angina UA(12 male and13 female)were enrolled in this study all taken from Coronary Care Unit (CCU)at AL - Yarmouk Teaching Hospital.Each patient was clinically examined by the consultant cardiologist and the diagnosis was achieved by electrocardiograph (ECG), and cardiac enzyme levels.Venous blood sample (ten milliliters) was drawn from each patient and control after (10 - 12) hours overnight fasting, using a 10 ml disposable syringe between 9.00 and 11.00 A.M.The sample was divided into two portions one for testing Hb concentration and the other part was centrifuged to obtain serum, to be used for measuring the following variables : serum vaspin, serum omentin - 1 and Troponin I Fast, total cholesterol, triglyceride, High density lipoprotein cholesterol and low - density lipoprotein cholesterol, fasting blood sugar, serum creatinine and uric acid.Body mass index was calculated according to the following equation : BMI=weight/height2, also blood pressure was measured.Results : Serum vaspin and omentin - 1 levels were significantly lower in patients groups in comparison with control group, while serum Troponin I fast, total cholesterol, and low density lipoprotein cholesterol levels were significantly higher in patients with coronary artery disease than controls. Negatively significant correlation was found between serum vaspin and omentin - 1 with (BMI, total cholesterol and troponin I Fast).Conclusion : Serum Vaspin and Omentin - 1 levels were lower in acute coronary syndrome patients in comparison with control group, serum vaspin and omentin - 1 showed significant changes with the development and progression of acute coronary syndrome and would be valuable in the assessment of patients with acute coronary syndrome.Vaspin and Omentin - 1 may be used as a predictor of ACS.

المستخلص: مرض السكري من النوع الثاني هو اكثر اشكال مرض السكري شيوعا ويتميز باختلال افراز الانسولين واختلال فعاليته ويكون مصحوبا بمشكله زياده الممانعه للانسولين(وهي الحاله التي يكون فيها كميه الانسولين الطبيعيه تكون غير كافيه لانتاج نفس الفعاليه الايضيه في الخلايا | Type 2 diabetes is the most common form of diabetes and is characterized by disorders of insulin action and insulin secretion, and associated with increase problem of insulin resistant which is the condition in which normal amounts of insulin are inadequate to produce a normal insulin response from fat, muscle and liver cells. Insulin resistance in fat cells results in hydrolysis of stored triglycerides, which elevates free fatty acids in the blood plasma. Insulin resistance in muscle reduces glucose uptake, whereas insulin resistance in liver reduces glucose storage, with both effects serving to elevate blood glucose. High plasma levels of insulin and glucose due to insulin resistance often lead to metabolic syndrome.The combination of hypertension, dyslipidemia, insulin resistance, hyperinsulinemia, glucose intolerance, and obesity, particularly central obesity, has been termed the “metabolic syndrome.” It has been proposed that this syndrome is a powerful determinant of type 2 diabetes and cardiovascular disease.Material and measurements : The study is designed to measure BMI, FBS, TG, HDLc, and c - peptide and insulin level. history of hypertension, age of patients and duration of diabetes are Also taken in to account. These parameters and measures applied for forty five patients with diabetes and thirty normal as control subjects.Results : - There is a positive significant Correlation between insulin level of the diabetic patient and BMI - there is Also a positive significant correlation between insulin level and C - peptide in diabetic patient (r=0.781) (p=0.0001) and in healthy control (r=0.599) (p=0.0001). - There is a positive significant Correlation between C - peptide level of the diabetic patient and BMI - There is a significant negative correlation between HDL with HbA1c, in diabetic patient (r= - 0.423) (p=0.006) and significant correlation of HbA1c with FBS - There is a positive significant Correlation between duration of diabetes and age of the patient(r=0.783) (p=0.0001) - There is a significant negative correlation between C - peptide and duration of diabetes in diabetic patient (r= - 0.310) (p=0.045) - There is a significant correlation between TG with FBS values. - There is a negative significant correlation between TG with HDL values. - 37.8% of diabetic patients had metabolic syndrome and no one of the control subjects had the criteria of (WHO).Conclusion : There were large percentage of diabetic patients with different BMI had metabolic syndrome as compared with the control subjects. There were strong correlations between insulin level (hyperinsulinemia) and risk of metabolic syndrome development and appearance of its complications. The risk of hyperinsulinemia and metabolic syndrome was well correlated with BMI than with HbA1c. Most of over weight and obese patients had high insulin level with different degrees of glycemic control and duration of disease. Large number of patient with metabolic syndrome were hypertensive as compared with diabetic patients with out the syndrome.

المستخلص: الاستسقاء هو مصطلح يطلق على الجهاز الهضمي لتراكم السوائل في التجويف البريتوني (البطني) الناجمة عن كل من الامراض غير الخبيثة مثل تليف الكبد، والتهاب الصفاق السلي... الخ، والامراض الخبيثة مثل سرطان غشاء البطن المنتشر، وسرطان الثدي وسرطان المبيض. لقد تم | Ascites is a gastroenterological term for an accumulation of fluid in the peritoneal cavity caused by both non - malignant disease such as cirrhosis, tuberculous peritonitis..etc, and by malignant disease such as metastatic adenocarcinoma, breast cancer and ovarian cancer. The work in this thesis was done to evaluate the role of the multiple biochemical parameters and group of tumour markers in the differentiation between malignant ascites from non - malignant ascites. A number of parameters were obtained from (60) sixty patients : (30) thirty with malignant ascites and (30) thirty with non - malignant ascites (as controls), all patients admitted to the department of gastroenterology in Medical City - Baghdad Teaching Hospital, Oncology Teaching Hospital and Al - Amal Hospital between December 2013 and July 2014. The biochemical parameters and tumour markers which have been measured in the present study included : total protein, albumin, uric acid, calcium(Ca++), carcinoembryonic antigen(CEA),cancer antigen(CA19 - 9), cancer antigen(CA15 - 3), cancer antigen(CA125) and ? - human chorionic gonadotropin (? - hCG).The statistical analysis for the data obtained in the present study showed : 1 - Highly significant increase of CA15 - 3, ? - hCG and ascitic fluid/serum (A/S) total protein ratio in malignant ascitic fluid while there is significant decrease of serum ascites albumin gradient (SAAG) and serum ascites cholesterol gradient (SACG) in malignant ascites compared with non - malignant ascites patients (p<0.0005, p<0.0005, p<0.05, p<0.0005 and p<0.005 respectively). Thus the level of these parameters in ascitic fluid could be used as a good parameters in differentiation between malignant ascites from non - malignant ascites patients.2 - Significant increase in serum CA15 - 3 and ? - hCG level in malignant ascites patients compared to non - malignant ascites (p<0.05 and p<0.0005 respectively). 3 - Significant increase of CEA, CA19 - 9, total protein, albumin, uric acid and Ca++ level in ascitic fluid of malignant ascites patients compared to non - malignant ascites (p<0.0005, p<0.005, p<0.005, p<0.005, p<0.05 and p<0.05 respectively), thus the level of these parameters in ascitic fluid could be used as a helpful parameters in differentiation between malignant ascites from non - malignant ascites patients. 4 - Significant increase in serum of CEA, CA19 - 9, albumin, uric acid and Ca++ level in malignant ascites patients compared to non - malignant ascites (p<0.05, p<0.05, p<0.05, p<0.05 and p<0.05 respectively) while there is no significant differences in serum total protein level of malignant ascites compared to non - malignant ascites (p>0.05). 5 - CA125 level in ascitic fluid and serum of malignant ascites patients shows no significant increase compared to non - malignant ascites (p>0.05 and p>0.05 respectively), therefor CA125 test in ascitic fluid cannot be used as a parameter in differentiation between malignant ascites from non - malignant ascites patients.CA15 - 3, ? - hCG, (A/S) total protein ratio, SAAG and SACG can be considered as a good parameters in differentiation of malignant from non - malignant ascites, while CEA, CA19 - 9, total protein, albumin,Ca++ and uric acid level in spite of their increase in malignant ascitic fluid but this increase is not considered as a diagnostic factor and can be used as a helpful parameters in the differentiation between malignant from non - malignant ascites. CA125 has no useful role in diagnosis or differentiation between malignant from non - malignant ascites.

المستخلص: المقدمة : يعرف الاسقاط المهدد بانه حالة يمكن ان تصيب معظم النساء الحوامل في بداية الاشهر الثلاث الاولى من الحمل ,يتميز بحدوث نزيف مهبلي مصاحب بالام في البطن والظهر ويمكن ان ينتهي اما بحدوث اجهاض فعلي وموت الجنين او اكمال اشهر الحمل والانتهاء بالولادة.الهدف | Threatened abortion can defined as failure of pregnancy and vaginal bleeding and this occur before twentieth weeks of pregnancy. Aim of study : To evaluate association between maternal serum levels of angiogenic growth factors (sFlt - 1 & PlGF) with threatened abortion by compare it with control healthy level, to evaluate association between maternal serum level of oxidative stress marker (Glutathione peroxidase) with threatened abortion by compare it with control healthy level. To investigate if maternal serum levels of these parameters can be used as predictive markers for outcome of threatened abortion. Subjects & Method : Eighty six women were included in this study with age range from (20 - 35) years, all women attended to Obstetrics and Gynecology department / Alyarmook hospital during period from December 2015 to March 2016.Subjects were divided into three groups(1)Non pregnant women (in luteal phase) : 16 women serve as control group ( 2) Normal pregnant women with gestational age between (6 - 12) weeks : 20 women serve as patient study group(3) Threatened abortion women with gestational age between (6 - 12) weeks with vaginal bleeding : 50 women serve as patient study group. All threatened abortion women had been followed up for 6 months to determine whether they complete their pregnancies with live birth or subsequent miscarriage. Women with or without history of previous abortion, cigarette smoking were included and excluded women with age below 20 years and above 35 years or with diseases like (Hypertension, Diabetes mellitus, Hyperthyroidism) and women in follicle phase. All serum samples were analyzed for soluble fms - like tyrosine kinase - 1 (sFlt - 1), placental growth factor (PlGF) and Glutathione peroxidase by using (ELISA) technique.Results : There was significant lowering in mean value level of sFlt - 1 in threatened abortion women (8.5 ± 4.4 ng/ml) than normal pregnant women (13.8 ± 3.2 ng/ml)and non - pregnant women (15.3 ± 3.2 ng/ml), P value
