The study consisted of the investigation about Hepatitis B virus in the saliva as compared with serum by using the ELISA and Real Time PCR techniques as well as the detection about antigens and antibody to this virus in serum. It also seeks about the liver functions enzymes and evaluating the extent of its importance for diagnosing liver disease resulted that virus. However, the obtained results showed that HBsAg antigen was found in 99.4% and (1.101± 0.335) mean ±SD in serum as compared with 48.6% in saliva with a (0.330±0.278) mean ±SD, that gave a noticeable increase when comparing it with the control group which was (0.0039± 0.0024) and (0.0017±0.0014 ) for serum and saliva respectively. The value of T test for serum and control group was (16.25) , while the value of T test for saliva and control group was (4.18). The proportion of correlation between saliva and serum in ELISA test was equal to (0.361) with high significance of test while the value of T test for them was (28.902) with high significance of test. The results have also stated that the age groups involved in the experiment contributed as being high proportion of infection in the serum, but in the saliva, these proportions were different and it has been found that the high proportion of infection was 53.3% in the group (10 - 20) yrs., While the lowest proportion was 38.4% in the (31 - 40) yrs. Moreover, it has been concluded that the number of males exceeded the number of females, but the number of females was the most infected with HBsAg in the experiment group. However, the total number of males was 91, It was found that 90 males have positive test to the HBsAg in serum with a proportion equals 98.9% whiles 42 males have a positive test to the HBsAg in saliva with a proportion equals 46.1%. on contrary, the number of female was 84 female and all of them had a positive test to the HBsAg in serum with a proportion 100% and 43 females have a positive test to the HBsAg in the saliva with 51.1 % as compared with control group which included 15 males and 10 female. All of them were negative to the HBsAg test in serum and saliva... The levels of HBV DNA were determined in the samples of positive saliva to ELISA test by using Real Time PCR. 95% from tested serum samples were positive to the viral load While in saliva 50% from the samples was HBV DNA positive. The results also showed that soluble antigen HBeAg has been detected in 24 patients with 13.7% from a total 175 patient as compared with the control group that showed a negative result to this antigen. As for the antibodies, it has been found that anti - HBc IgM was found in only 5 patients with 2.5% while anti - HBc IgG was found in 170 patients with 97.2% from the total number of patients. The control group revealed negative result for these two antibodies. The anti - HBeAg was in 150 patients with 85.7% from the total number of patients. There were no positive patients to this antibody in control group. The anti - HBs wasn’t found in any patient but it was found in the half of control group. This emphasizes to immunize against HBV in those members. The results also exposed that there was a noticeable increase in liver enzymes that it was found that ALT the elevated levels of were found in 76% of patients. As compared with the control group which has normal values 100%. As for AST enzyme was elevated in 60.6%, As compared with the control group which was normal 100%.It has been observed that ALP enzyme was elevated with a 38.4% in the experiment patients as compared with the control group which was normal 100%. Finally, the total values of TSB was elevated in 35.5%, As compared with control group which was normal 100% with (0.52±0.19). Nevertheless, it has been noticed that it cannot be judged about the person's blood on the basis that it is healthy in case of absence of surface antigen unless it is certain that his/her blood is free from HBV DNA by using the technique of Real Time PCR - since many patients who heal from past infection or their infection in a time of passive and amounts of HBV DNA can't be diagnosed by using the ELISA technique

Three species were chosen each species represent the environment which collected from it. These species were Anabaena oryzae, Nostoc linckia, Anabaena laxa. The effects of some environment factors on growth and biological products quantity has been studied in the three species above. The effects of the temperature showed that 26°C was the best for growth and biological products quantity than 16°C and 36°C. While the pH effects showed that pH 7.6 was the best for growth and biological products quantity than pH 6.6, 8.6. Three light intensities were used 1250, 2500, 5000 lux were used. The results showed that the light intensity of 2500 lux was the best for daily growth and quantity of extracted biological products. While the study of the effects of addition of macronutrient and micronutrient to Asm - 1 media which used for culturing of the three species of cyanobacteria by replacement of NaCl by NaNO3 in the medium, showed that there is an increase in daily growth and quantity of extracts of biological extracts, also the addition of FeSO4.7H2O and NaNO3 together showed further increase of daily growth and biological extracts quantity. The biological products has been identificated by HPLC - MS, IR and NMR. The results showed the presence of the neurotoxin Anatoxin - a and the hepatic toxin Microcystin in its various forms MCYST - LAba, MCYST - YM(O), [D - Asp3, Dha7]MCYST - LR and MCYST - YA in the biological products of Anabaena oryzae. The results also showed the presence of the hepatic toxin MCYST - YM(O) and [D - Asp3, Dha7]MCYST - LR in the extracts of the two spices of cyanobacteria Nostoc linckia and Anabaena laxa.The results also showed that the Muller Hinton Agar media is better than the Blood Agar media in testing the activity of these extracts in inhibition of the pathogenic bacteria, the method of holes is better than saturated discs, and the solvent DMSO (Di - Methyl Sulpho Oxide) is the better in testing of biological activities, while the filtrate of cyanobacteria did not shown any activity for inhibition of the pathogenic bacteria which include : Escherichia coli, Streptococcus pyogenes, Pseudomonas aeruginosa, Klebsiella pneumonia, Proteus Vulgaris, Staphylococcus aureus. The results showed the high capability of inhibition in concentrations of 1000, 2000, 3000 µg/ml of the extracts of the cyanobacteria Anabaena oryzae, Nostoc linckia and Anabaena laxa on the above pathogenic bacteria and some times more efficient than antibiotics used for comparison, and the concentration 3000 µg/ml was the most effective.The effects of biological extracts of the three species in concentrations of (1000, 2000, 3000) µg/kg of body weight on tested albino mice, using injection and feeding methods, was studied. The results showed poisoning nervous symptom for the first few hours, while the results showed hepatic poisoning symptom on the dissecting animals. The anatomic symptoms included changes the colour of the liver to darkening and appearance of necrosis, in addition to becoming lobbed and swollen some times with bleeding.While the poisoning effects on dissecting tissues of livers of the animals showed a simple swollen and some times assured in all of the liver accompanying with increase in growth and cell division, as well as increases in lymphatic cells inside the tissue and in general in liver tissue. The lymphocyte seemed bigger than for normal cell with multi - nuclei in white blood and increase in cell size and destruction of liver tissue. Nostoc linckia was the greater urging for cell division consequently probably more induce of cancer in the liver of the animals, while the biological product of Anabaena laxa showed more poisonous for liver cell than the biological products of Anabaena oryzae, the least effective in cytotoxic and urging cancer cell in liver of the animals.

المستخلص: A total of 359 samples divided as 228 clinical and 131 non clinical specimens were collected during 2012 from four hospitals in Baghdad city including : Al - Kadhymia Teaching hospital, Baghdad Teaching hospital, The Burn Specialist Hospital and Al - Imam Ali hospital, for isolation of P.aeruginosa to study the correlation between collagenase production and biofilm formation. Eighty two Pseudomonas isolates were screened for biofilm formation, 28 isolates were classified as strong biofilm formers, 25 as moderate and 27 as weak biofilm former. The 28 isolates were identifid by VITEk - 2 Compact system which confirmed that the isolates were P.aeruginosa. Collagenase production assay was used to screen 28 isolates that were strong biofilm formers inorder to detect the ability of these isolates to produce collagenase, the substrate of collagenase (collagen) was purified localy from bovin tendon and the results showed that just 8 isolates could grow in mineral salt media with collagen after 4 days of incubation. The factors affecting biofilm formation and collagenase production were studied to determine the optimual conditions for their production, those factors included : 1 - Nitrogen sources represented higher influence on collagenase production specialy (yeast extract) in media containing collagen than other media without collagen as a substrate. The specific activity differed between the 8 isolates, biofilm formation also became more pronounced with (yeast extract), while NH4Cl and NaNO3 depressed biofilm formation at the same conditions. The statistical analysis between the two parameters (biofilm and collagenase) according to different nitrogen sources demonstrated highly significance at p?0.01 with yeast extract and casein. 2 - pH, results showed that the best pH for production was 7 for both collagenase and biofilm.The statistical analysis for determination the relationshipe between the two parameters showed highly significance at p ?0.01 for different pH. 3 - The maximum production of the two parameters was at 35?C temperature which gave highly significance at p?0.01 with defferent temperature. 4 - Long incubation periods revealed increasing in collagenase production and biofilm formation which represented highly significance detween them when incubation periods were prolonged at p?0.01. Results of this study showed that collagenase production increases when bacteria switch from a planktonic to biofilm phenotype. This indicates that biofilms and collagenase are more virulent and have a greater ability to cause tissue destruction. The REP - PCR analysis using BOX - primer, showed a clusters genetic relatedness among the isolates. The isolates were grouped according to the REP - PCR in 9 different genotypes, named cluster 1 to 3 which included C1, C2, C3 with relatedness : 8 (80%), 8 (86%), 3 (80%) respectively. A19 and A20 both of them were not included in any cluster, they have 78% similarity.The REP - PCR analysis showed that the genotypic relatedness is consistently high between the 8 producer isolates and non producer isolates (13), showed similarity reached 86

المستخلص: توضح هذه الدراسة عزل lipA gene من الزوائف الزنجارية من مياه الصرف الصناعية للزيوت النباتية وتشخيصها اعتمادا على تفاعل البلمرة المتسلسل (PCR). استغرقت هذه الدراسة تسعة اشهر, من شهر شرين الاول 2014 لغاية حزيران 2015. تم جمع خمسين عينة من مياه الصرف الصناع | This study clarify the isolation and identification of lipA gene in Pseudomonas aeruginosa from industerial wastewater of vegetable oils factories depending on the polymerase chain reaction (PCR) technique. The present study had taken nine monthes starting from October 2014, till the mid of June 2015. Fifty samples of industrial wastewater were collected from the factories of the general company of vegetable oils, fourty from AL Rasheed factory and ten from AL ameen factory, the samples collected from the physical, chemical and biological treatment units, and other different wastewater tanks departments. While the four sewage samples were collected from sewer service Baghdad /Alrustumaiya. For Identification of Pseudomonas aeruginosa, two types of tests were used in this study. The first type was the routine tests, which include selective cultures, bacteriological and biochemical tests. Thirty four of fifty samples (68%) gave a positive growth and results for tests that were used to confirm the presence of P. aeruginosa. In addition to diagnosis P. aeruginosa in sewage sample which prepare the biological treatment units in vegetable oils factories as active sludge, other bacterial types have been diagnosed by using traditional methods and API 20 E system. For detection of bacterial lipolytic activity, two methods were used for this purpose, the first was the screening of bacterial lipolytic activity which was based on values of clear zones diameter around bacterial colony. The best values were between (1.9 _ 2.7) cm. The second test was carried by the Gas - Chromatography - Flame ionization detector, fatty acids solutions that were produced from hydrolysis by lipase enzyme were extracted by Petrolium ether solvent then analyzed by gas chromatograph apparatus. The second type of test was the Molecular diagnosis by using the Polymerase Chain Reaction (PCR) to detect lipA gene in Pseudomonas aeruginosa by two primers. Through two primers used, lipA 948 was the best and more specialized primer to isolation lipA gene of P. aeruginosa. It gave (100%) a positive result. While the second primer lipA 558, gave (66.66%) a positive result and that may be due to the design of this oligonucleotides was not specific for lipA of P.aeruginosa. This is so as was based on highly preserved region of 12 bacterial lipA - homologous genes for many genus and many species belong to Pseudomonas. DNA sequencing done for amplicon generated using lipA 948, this sequence aligned by using BLASTn software against NCBI database to validate the results and investigate the similarity degree with other corresponding strains.

المستخلص: Three experiments were conducted on two cultivars of sweet pepper Capsicum annuum L.; Flavio F1 and California wonder, to study the effect of seaweed extract and amino acids mixture and their combination on some vegetative and reproductive parameters, and some physical and qualitative characters of fruits. In addition, the chemical composition of leaves and some anatomical characters of stems were also evaluated. Furthermore, the effect of some treatments on genetic variations in both cultivars were studied. The field experiments were carried out at the fields the College of Agriculture/Al - Qadisiya University. The experiment was started at 18 - 1 - 2013 and ended at 3 - 7 - 2013. Seaweed extract, Basfoliar Kelp SL, was used at two concentrations; 3 or 6 ml. L - 1 in addition to control treatment (distilled water only). Also, a mixture of amino acids was used at two concentrations; 400 or 800 mg. L - 1 in addition to control treatment. Spray with the two substances was done in the early morning. The treatments were designed as a factorial experiment with two factors (3X3) in a randomized complete block design with four replications. The vegetative characters measured included; plant height, number of branches, percent of dry weight of shoot and root, and leaf chlorophyll content. Also, nitrogen percent, phosphorus and potassium content in leaves and roots was determined. The flowering and yield characters included; total number of flowers per plant, fruit set percentage, and total fruit yield per plant. In addition, weight, size, diameter and fruit length were measured. Vitamin C, total phenols, TSS, total sugars, alkaloids percent and the capsicin were measured in fruit juice. The anatomical characters of plant stem were included; epidermis, cortex and vascular bundles thickness, diameter of vascular units and pith thickness. The laboratory experiment was carried out during the period from 2 - 9 - 2013 till 16 - 10 - 2013. Spray with the two substances and their combination, at the same concentrations as used in the field experiment, was done on plants at the true leaves stage. The experiment was design as a factorial experiment with two factors in completely randomized design with four replications. The chemical characters measured in leaves included; content of auxin and gibberellin like substances, activity of catalase and peroxidase enzymes, amino acid content in addition to protein and sugar percent. Also, the genetic variation and genetic distance degree due to some treatments compared to control treatment using the RAPD with five primers was studied. The results were as the following : 1. Using seaweed extract and amino acids mixture, especially at the higher concentration, caused a significant increase in all vegetative characters measured for the two cultivars. 2. There were a pronounced increase in nitrogen percentage in plant shoot and root as the concentration of the treatments increased in both cultivars. 3. Increasing the concentration of the two factors caused an increase in phosphorus content in plant shoot of both cultivars. In roots, the use of the higher concentration of seaweed extract increased phosphorus content in Flavio F1 cultivar only. on the other hand, there was no significant effect on the mineral content in California wonder cultivar. Also, there was no significant effect on the phosphorus content in both cultivars due to the use of the two concentrations of amino acids and the combination of the two factors. 4. The use of seaweed extract caused a significant increase in potassium content in the shoots of the two cultivars. Also, the two concentrations of the amino acids caused an increase in the mineral content in shoots of the Flavio F1 cultivar only, while there was no effect in the California wonder cultivar. In roots, there was a significant effect due to the use of seaweed extract on potassium content, while there was no effect due to the use of the amino acids in Flavio F1 cultivar. In California wonder cultivar, no significant increase in potassium content was recarded in roots due to the use of all concentrations. 5. Seaweed extract and amino acids extract concentrations caused significant increase in total flowers number, fruit set, number of fruits per plant, plant yield and the physical characters of fruits, where the higher concentration of the two substances used gave highest values of fruit diameter, weight and size in both cultivars. Fruit length was not affected in Flavio F1 cultivar only. 6. The use of the two substances caused pronounced increase in TSS, sugars, vitamin C and phenols in the fruit of the two cultivars. Also, The use of seaweed extract had no effect on total alkaloids in Flavio F1 cultivar. While the amino acids mixture at the two concentrations increased alkaloids percent in fruit of the two cultivars. Also, there was a clear increase in the active ingredient (capsicin alkaloid) as the concentrations of the two substances used increase. 7. Both substances increased the auxin like substances in leaves of the two cultivars. The gibberelline like substances did not affect due to the use of seaweed extract of either cultivars. Amino acids had no significant effect. 8. The use of seaweed extract and amino acids mixture and their combination caused a significant increase in catalase and peroxidase activity in leaves, except the activity of peroxidase in leaves of California wonder cultivar which not affected by the seaweed extract. 9.Total free amino acids content and protein percent increased as the concentration of the two factors increased. Also, seaweed extract had significant effect on the percent of the total sugar. Amino acids treatments had no effect on sugar percent. 10.Using seaweed extract or amino acids caused an increase in epidermis and cortex thickness and size of vascular bundles of stem of both cultivars. 11.The use of seaweed extract, especially at the higher concentration, had significant effect in increasing the diameter of vascular units, while there was no effect due to the use of the amino acids. 12.There was a negative effect of the seaweed extract on pith thickness due to the use of the seaweed extract. on the other hands, the amino acids treatments caused an increase in stem pith. 13.The combination between seaweed extract and amino acids treatment had significant effect on most of the morphological, physiological and anatomical characters studied for both cultivars. 14.Increasing concentrations of seaweed extract and amino acids mixture or their combination caused an increase in DNA and RNA content in leaves of the two cultivars. The increase was greater at the higher concentration of both substances used. 15. Treatment with some concentrations of seaweed extract and amino acids and their combination produced plants with genetic variation as compared to the control plant using RAPD technology with five primers. The variation ranged from 13.04% using OPB - 9 primer to 33.33% using OPB - 4 and OPB - 11 primers in Flavio F1 cultivar. In California wonder cultivar, the variation ranged from 4.35% using OPB - 14 primer to 73.33% using OPB - 5 primer.

المستخلص: تعد الاصابة ببعض العوامل المرضية مسؤولة عن حوالي خمس حالات السرطان في العالم. وهنالك العديد من الاصابات الطفيلية التي ثبت دورها كمسبب او محفز لسرطانات معينة، الا ان العلاقة بين الاصابة بالاكياس المائية والسرطان مازالت موضع جدال ولذلك فقد هدفت الدراسة الح | Infectious agents are responsible for about one fifth of all cancer cases worldwide. Some parasitic infections are well documented to cause certain cancers. However, the association of hydatid cyst (HC) with cancer is a controversial issue. The current study aimed to investigate the possible association between chronic hydatid cyst infection with liver and lung cancers. The study involved three groups : the first group included 42 patients with HC, the second group included 35 patients with liver (12) and lung (23) cancers, while 25 apparently healthy individuals were recruited to represent the third group (control). Number, diameter, location and the status (calcified or non - calcified) of the HC were recorded from HC group. Blood samples were collected from the studied groups from which serum were separated and kept until being used. Enzyme linked immune - sorbent assay (ELISA) was used to estimate serum levels of anti - HC IgG antibodies, carbohydrate antigen (CA19 - 9), alkaline phosphatase (ALP) and ? - glutaml transferase (GGT), while Absorbance measured by spectrophotometric method was used to determine levels of lactate dehydrogenase (LDH) and adenosine deamimase (ADA).All members of HC group gave positive result for anti - HC IgG antibodies compared to 11 patients from cancer group and oneindividual from control group (Odds ratio =8.3). Both HC and cancer groups showed significantly higher p<0.05 levels of CA19 - 9, ALP, LDH and GGT ((76.16±58.26 U/ml and 110.77±96.47 U/ml), (131.81±76.65 U/L and 141.72±97.23 U/L), (244.24±117.94 U/L and 254.68± 115.56 U/L) and (95.06±66.73 U/L and 105.12± 41.42 U/L) respectively) than control group (10.81± 9.12 U/ml, 65.14± 25.21 U/L, 146.15± 37.59 U/L and 17.21± 6.87 U/L respectively). In cancer group, casp - 8 level (72.20±54.72 picomol/ L) was significantly lower from than that of control group (92.30± 41.20 picomol/L) and insignificantly from that of HC group (60.86±40.84 picomol/L). In HC group, ADA level was 47.84±10.65 U/L and was significantly higher p<0.05 than that of cancer group (10.14± 1.99 U/L) and control (16.09±2.70 U/L).Investigation for the risk factors which may increase the risk of developing liver or lung cancers in HC patients revealed that male, smokers and rural residents were more susceptible for such development (Odds ratios : 3.45, 6.982 and 5.48, respectively). Number and cyst size were significantly correlated with the level of anti - HC IgG antibodies (r= 0.539, P<0.001 and r= 0.618, P< 0.001 respectively), while calcified cysts associated with significantly higher levels p<0.05 of CA19 - 9 and GGT (105.03±88.9 U/ml and 145.46±101.57 U/L, respectively) than that of non - calcified cysts(65.91±39.87 U/ml and 77.17±7.23 U/L, respectively). Average level of anti - HC IgG antibobodies in calcified cysts was 19.75±13.11U/ml and was significantly P<0.05 lower than its counterpart of non - calcified cysts (85.017±76.84 U/ml). All studied parameters showed significantly higher levels in livers cysts than their counterparts in lung cysts. Results of the current study indicate that chronic infection with HC can increase the host susceptibility to develop liver or lung cancer.

المستخلص: This study was conducted on 20 male of Swiss albino mice, where the main target of this study was to identify the influence of copper nanoparticles (Cu - NPs) on some organs of the male reproductive system. Animals were orally administered with 0.1 ml of 100 mg/kg Cu - NPs for 7, 14, 21 days. Then the animals were dissected in the next day after the end of the dosing period and took from them testes and epididymis (head and tail) to study the parameters in which these particles have affected, and this parameter as follows : 1 - Changes in the weights of each of the animals bodies, testes, tunica albuginea, and epididymis (heads and tails). 2 - Changes in sperm characteristics in testes and epididymis (head and tail), which included : the percentage of live sperms, abnormal sperms and sperm concentration. 3 - Changes in the percentages of the spermatogenic cells, which included : a - Spermatogonia. b - Primary & Secondary Spermatocytes. c - Spermatids. d - Sperms. 4 - Changes in numbers of leydig cells and nuclei diameters. 5 - Changes in diameters of seminiferous tubules and their lining wall thickness. 6 - Changes in thickness and height of epithelial cells in both the head and tail of the epididymis. 7 - Histopathological changes in testes and epididymis (head and tail). Phenotype description of testes from mice treated with copper nanoparticles for a period of 21 days occurrence of congestion and a few amount of fatty material around the testes. The results also revealed a decline in the average body weights on the period of 7 and 21 days of treatment when compared with the weight of the same animals before treatment and the decline was significantly at (P<0.05). Whereas the testes and tunica albuginea weights recorded a significant decrease in their average weights (P<0.05) when compared with control groups. As well as the epididymis weights where showed significantly decrease (P<0.05) in the average of the epididymides heads weights for all three periods of treatment, while a significant decrease (P<0.05) in the average weight of the epididymis tail appear for two periods 7 and 21 days compared with control groups. The study also reported a decrease in the percentage of live sperm and the average sperm concentration and an increase in the percentage of sperm abnormalities extended to all periods of treatment compared with control groups and this change was significant at the level of (P<0.05). The number of leydig cells and nuclei diameters, the results show a decrease in their averages and all the extended treatment period when compared with control groups, and this decrease was significantly at (P<0.05). Treatment with particles of copper nanoparticle indicated a decrease in the percentage of spermatogonia, primary spermatocytes and sperms in all periods of treatment compared with control groups and this decrease was significantly at the level of (P<0.05). While the results of the study revealed a significant increase at the level of (P<0.05) in the percentage of secondary spermatocytes and spermatids compared with the control animals. The study also showed a significant decrease at the level of (P<0.05) in the diameter of the seminiferous tubules of testes and the wall thickness of the seminiferous tubules for all periods of treatment compared with control groups. As well as a reduction in wall thickness and height of the epithelium in epididymis (head and tail) for all periods of treatment compared with control animals and this decline was significantly at (P<0.05). The current study also recorded a textile damage in the testes and epididymis (head and tail), which summarized the crash of some seminiferous tubules, degeneration of lining cells in tubule, the appearance of vacuole between cells and lifting epithelium from the basement membrane. On this basis, this study has shown for the first time that particles of copper nanoparticles have a negative impact on the effectiveness and activity of the male reproductive system in albino mice.

المستخلص: تناولت الدراسة الحالية دراسة تشريحية مقارنة لتسعة مراتب من العائلة القرعية Cucurbitaceae المستزرعة والبرية والتي زرعت في الحديقة النباتية لكلية التربية للعلوم الصرفة ابن الهيثم والمراتب هي : 1 - Citrullus colocynthis Schrad2 - Citrullus vulgaris Schrad3 | The present study included comparative anatomical study for nine taxa of Cucurbitaceae family for cultivated and wild types, which were planted in the garden of College of Education for Pure Sciences/ Ibn Al - Haitham. These taxa included : Citrullus colocynthis Schrad, Citrullus vulgaris Schrad, Cucumis melo Linnaeus, Cucumis melo var.flexuosus Naudin, Cucumis sativus Linnaeus, Cucurbita maxima Duchesne, Cucurbita pepo Linnaeus, Lagenaria siceraria (Mol.) Standl, Luffa cylindrica (Linnaeus) M. Roem. This study focused on some the anatomical characterization as compared study for the first time to these taxa in Iraq. This study included the features of ordinary epidermal cells, leaves petioles, stems, pedicles and sepals of the studied taxa. The results found the appearance of stomata in the stems and petioles in straight line as adjacent planar shape to the epidermal cells and not scattered as found in the leaves, this result was seen for the first time in the current taxa. Furthermore, the stomata have been shown in pedicel and sepals in same type as the stomatal complexes in leaves. The importance of phenotypic variation for the length and types of eglandular trichomes and the presence or not of glandular trichomes were found to carry out the role of indumentum in the different isolated taxa. Additionally, this study included the examination of the cross sections of the roots and also exposed the constituent tissues of it, the variation in the thickness of epidermis, cortex, vascular cambium as well as the arrangement of phloem cells have an important role in the studied taxa. The cross sections of stems, leaves petioles and pedicles showed shape and studied a significant role in the studied taxa and split them into groups.Moreover, this study concluded that the following of above sections from the outside into the inside has an important role to find out their constituent tissue. Thus the results of the study clarified the importance of epidermis tissue through the explanation of the outer and inner tangential walls of their cells and the variation in their dimensions, thickness and kind of stomatal complexes; therefore it has been given the importance of those features in the studied taxa in this study. Cortex tissue showed an extension of angular collenchyma and chloronechyma from stem to pedicel and have shown variation in the thickness in these two layers which was useful in the classification of studied taxa. Vascular tissues differed in the shape of vascular bundle, the number of rows and xylem units and the arrangement of the internal phloem, and all of those characteristics have helped in the studied taxa. In addition, the vascular tissues helped to find their arranged in the stems and found as vascular cylinder shape, while in the petioles and pedicel shown as vascular ribbons were which took the shape of sections petioles and pedicel. The medullar cells and medullary rays have been studied and also their similarity in the morphological characterization and function. Moreover, the anatomical features of the vertical sections of the laminae of leaves in mesophyll tissue have been examined, in the thickness of palaside and spongy layers in midrib, the variation in number and arrangement of vascular bundles have an important role in the studied taxa. In the current study, the ordinary and petal leaves venation and the type of venation have been studied in the studied taxa.

المستخلص: Polycystic ovary syndrome is the most common endocrinopathy in women, affecting 5 - 10% of women of reproductive age.The principal features of PCOS are anovulation, resulting in irregular menstruation, amenorrhea, ovulation - related infertility, and polycystic ovaries; excessive amounts or effects of androgenic hormones. Leptin, a key hormone in energy homeostasis and neuroendocrine function, has a permissive role in the pathogenesis of reproductive dysfunction. Aim of the study To assess the role of serum leptin in women with PCOS and to evaluate leptin levels in PCOS women before and after treatment with metformin. Materials and Methods This prospective experimental study included 60 women of reproductive age (18 - 38years) were allocated to four groups : 15 obese women with PCOS (BMI >30 kg/m2), 15obese controls, 15 non - obese women with PCOS (BMI 18 - 30 kg/m2), and 15 non - obese controls. Serum leptin and insulin levels were measured and compared between case and control subjects also comparison done before and after treatment with metformin. Results There was a significant increase in leptin in non - obese PCOS group (8.2±2.73) compared to non - obese control (5.64±1.43), (P value=0.0032), insulin level was significantly higher in PCOS group (15.87±6.65) than control (5.47±1.68), (P value<0.001). There was significant decrease in BMI, leptin and insulin levels after 12 weeks of metformin treatment in obese and non - obese PCOS subjects. Conclusions Leptin level increased remarkably with increasing body weight. It is higher in non - obese PCOS women in comparison with non - obese healthy women. Treatment with metformin for 12 weeks resulted in significant reduction in leptin levels in both obese and non - obese PCOS subjects.

المستخلص: تسلط الدراسة الحالية الضوء على تشخيص وتحديد نسبة الاصابة بطفيلي الاميبا المرضية المتمثلة بالاميبا الحالة للنسج Entamoeba histolytica وتمييزها عن الاميبا غير المرضية المتمثلة بالاميبا المتغايرة Entamoeba dispar اللتين تتمايزان بشكلهما المتماثل في كلا الطور | This study sheds light on the determination and diagnose of the percentage of infection of like Entamoeba histolytica and differentiate it from the non pathogenic Entamoeba dispar that were morphologically identical in both cysts and trophozoite phase in two different groups : the first group includes 50 stool samples of patients suffering from diarrhea and abdominal pain (symptomatic group) while the second group includes 95 stool samples of patients not suffering from diarrhea and abdominal pain (Asymptomatic group).In addition to that, 20 stool samples were collected from healthy individuals as a control these samples were collected patients of AL - Zafaranyia General Hospital and AL - Alwyia Childhood Teaching Hospital in Baghdad from July, 2011 to May, 2012.These samples belong to different ages (1 year - < 50 years) of different sexes (males and females). Entamoeba samples were diagnosed by using two methods : the first one is the wet mount as a General Stool Examination(GSE) after macroscopic examination for sample and classifying them according to their consistency (solid, semisolid and liquid) and color (brown and yellow) and presence of blood and mucous in addition to diagnosing them microscopically to detect the presence of pus cells and both phases trophozoite and cyst for Entamoeba histolytica.While the second method that was depended in diagnosis is duplex polymerase chain reaction (dPCR) by using two pairs of genes for detection of their amplification in DNA sample isolated from stool. The first pair is cystein proteinase which represents one of virulent factors in Entamoeba histolytica parasite as a tissue invader. The second pair encodes the surface antigen present on the surfaces of both parasites E. histolytica and E. dispar. It is represented by Actin gene (Act). The results of the wet mount showed that in percentage of infection of both species (E.histolytica/E.dispar) the (54%) of patient symptom and (34.37%) patient a symptom.While results of the specificity and sensitivity showed that in positive sample wet mount negative PCR while negative sample wet mount showed that positive PCR and higher percentage of infection the Entamoeba dispar. While the results of the dPCR showed that in spite of the presence of both species Entamoeba pathogenic (Entamoeba histolytica) and non pathogenic Entamoeba (Entamoeba dispar) , the percentage of infection of Entamoeba histolytica was lower than that of Entamoeba dispar. This was clear by the detection of amplification the Reaction producets (dPCR) by using both genes : Actin &Ehcp5 where only 8 samples were detected and they were found to be positive amplification Ehcp5 and 31 samples were positive amplification in both groups of patients (symptomatic and a symptomatic). The percentage of infection in females was higher than that in males for all ages when using both tests (wet mount & PCR). More over the patients with less than (10) years old had higher percentage of infection in both sexes.In conclusion, it should not be depended on direct wet mount technique for the identification of infected parasite Entamoeba histolytica and differentiating it from Entamoeba dispar because of their high homology. That the molecular examination is the only method that is able to determine the kind of infection with parasite Entamoeba

المستخلص: انقطاع الطمث لاسباب ثانوية هو انعدام الدوره الشهريه لمدة ثلاثة الى ستة اشهر للنساء اللواتي لهن دوره شهريه منتظمة.واستنادا لمنظمة الصحة العالمية ان انقطاع الطمث يتضمن مجموعة (WHOI) و(WHOII) والتي تكون (30%) من حالات العقم.وتعاني اكثر النساء ممن يكونون من م | Secondary amenorrhea refers to the lack of cycle for three months in a row or for more than six months in a woman who has had regular menstrual periods before, and its associated with conditions classified as World Health Organization (WHO) group 1 and WHO group 2 and has been estimated to represent almost (30%) of all causes of infertility. In clinical practice, WHO group 2 subjects present much more frequently than WHO group 1 subjects and they appear to be much harder to treat successfully. Among women classified as WHO group 2, those diagnosed with polycystic ovary syndrome (PCOS) constitute the largest group (60 - 85% of cases). These women account for most cases with oligomenorrhea (90%) and represent about (30%) of those with amenorrhea.ObjectiveThe aim of this study was to find out the pregnancy rate following intrauterine insemination (IUI) in women complaining of secondary amenorrhea after induction of ovulation and compare it with those achieve pregnancy by natural way.Material and MethodsSeventy five females with secondary amenorrhea were involved in this study, there ages were ranged between (?30, 30 - 39, ?40) years old with infertility duration ranged between (?2, 3 - 4, 5 - 6, 7 - 8, ?9) years. History and medical examination were done for all women, with tubal patency assessment by HSG or laparoscopy.By cycle day two, hormonal assay (S.FSH, S.LH, S.E2, S.Prolactin and S.Testosterone) were done for all females in addition to ultrasonography to exclude any ovarian pathology.Ovulation induction program was applied for all females which include either clomiphene citrate (CC) alone, recombinant Follicular Stimulating Hormone (r - FSH) alone or combined CC and r - FSH. Vaginal ultrasonography was done for all females on day 12 or13 to assess ovarian response (size and number of mature follicles) and endometrial thickness. Meantime all male partners undergo seminal analysis to assess sperm parameters (sperm concentration, sperm motility and morphology).Thirty eight of females participated for natural pregnancy and thirty seven of females participate for IUI. Washing swim up technique was used for sperm activation for all male partner involved in IUI group.Follow up of all these females for pregnancy test to assess the pregnancy rate for both groups (natural and IUI).ResultsThe pregnancy rate achieved by natural way for a women with secondary amenorrhea is (23.7%), and (18.92%) by IUI way.In this study, it was found that female age, infertility duration, hormonal balance and ovulation induction program affect the pregnancy outcome where the young age group and short infertility duration correlate positively with pregnancy rate. Furthermore, early diagnosis of underlying causes of secondary amenorrhea to achieve hormonal balance by suitable ovulation induction program, have an effect on pregnancy rate, were combined CC and r - FSH produce a significant result among females achieve pregnancy by natural way (13.5%) compared with other ways. While ovulation induction by r - FSH drugs produce a significant results (13.5%) among females achieve pregnancy by IUI way.ConclusionFrom results of this study, it was concluded that young female age, short infertility duration, early diagnosis of underlying causes of secondary amenorrhea and the use of r - FSH drugs for ovulation induction produce a high significant pregnancy rate using IUI program.

Seventy four isolates of Streptomyces were screened for cellulase production in solid and liquid media. The results showed higher capability of isolate Streptomyces sp. B 167 for cellulase production and bioconversion of cellulose. Therefore, it was selected for further studies. The results of optimization revealed that the cellulase enzyme productivity by the isolate Streptomyces sp. B 167 reached to 2.1 and 2.28 U/ml after 48 h of incubation time and pH 7 respectively. Cellulase productions in tested isolate improved (2.57 U/ml) by supplementation of cellulose liquid medium with 1 % of yeast extract as nitrogen source. Additives of carbon sources like (manitol, glucose, maltose, sucrose and starch) to the process of saccharification did not improve the cellulase productivity. The bioconversion of cellulosic waste to reducing sugar was maximum with Banana peels (77.78 %) followed by the rice husk (75.56 %), orange peels (71.11 %), corn steep peels (60.0 %) and lowest bioconversions (53.33 %) were recorded with sawdust. The degradation of cellulosic waste increased with increasing substrate concentration. Maximum cellulase productivity (3.18 U/ml) and bioconversion (86.1 %) was obtained at 3 % (w/v) of cellulosic waste (Banana peels). Saccharification of cellulosic waste with different treatment methods was studied. The pretreatment of cellulosic waste with 1 % HCl and H2SO4 produces 21 and 15.8 g of reducing sugar / 100 g of cellulosic waste. In comparison, hydrolysis with Streptomyces sp. B 167 enzymes resulted a significantly higher amount of reducing sugar yield (25 g / 100 g cellulosic waste). Further fermentation of cellulosic hydrolysates was performed using Saccharomyces cerevisiae using stationary fermentation condition. Maximum yield of ethanol were (0.30, 0.19 and 0.10 g ethanol / g glucose) observed with Streptomyces sp. B 167 enzymes, HCl and H2SO4 hydrolysates respectively after 48 h of fermentation

These samples include : (75) Urine, (28) stool, (28) of wound swabs and (9) sputum samples.The incidence of nosocomial infection was (45.7%) of them, urinary tract infections were (50.7%) from (75) samples, followed by wound infections (42.9%) from (28) samples, gastrointestinal infections (39.3%) from (28) samples then pneumonia (33.3%) from (9) samples the nosocomial infections were more common in females and age group 51 - 89 years. Different bacterial species were isolated in this study and the results showed that the most commonly isolated type was Citrobacter koseri in a proporation (21%) of urinary tract infections, followed by the following bacterial species : Escherichia coli (15.7%), Staphylococcus schleiferi (10.5%) , Staphylococcus epidermidis (7, 8%), Proteus vulgaris, Staphylococcus saprophytica, Klebsiella ozaenae, Klebsiella ornithindytica in aproportion (5.2%) for each, Enterobacter aerogenes, Providencia stuartii, Staphylococcus warneri, Staphylococcus aureus, Proteus mirabilis in aproportion (2.6%) for each.Citro. koseri were also the most common in wound infections (25%), followed by the following bacterial species : E.coli (16.6%), P.mirabilis (16.6%), Staph.schleiferi, P.vulgaris, Prov.stuartii and Prov.rettgeri in aproportion (8.3%) for each. Citro.koseri were also the most common in the gastrointestinal tract infections in a proporation (36.3%), followed by E.coli (18.1%), S.flexneri (18.1%), P.mirabilisc, Prov.stuartii, Prov.alcalifaciens in a proporation (9%) for each. . While Strept.pneumoniae was the most common(66.7%) in penemonia cases followed by K.pneumoniae (33.3%).The isolated bacteria were tested for antibiotics susceptibility and it has been found that most of these isolates showed high resistance to the studied antibiotics other than Prov. Stuartti was sensitive to all antibiotics except of Rifampicin and Tetracycline. As well as bacterial species belonging to the genus Staphylococcus were sensitive to Amikacin, Staph.aureus was also sensitive to Nitrofurantoin while Staph.warneri was also sensitive to Ciprofloxacin and Nitrofurantoin also Enterobacter aerogenes was resistant to all antibiotics except for Ciprofloxacin and Nitrofuratoin. Eleven of most commonly isolated bacteria which were multidrug resistant were chosen for the curing experiments using SDS to study the relationship of their plasmids with resistant to antibiotics. The results showed that the cured cells of E.coli lost their resistance to Tetracycline Ciprofloxacin and Cefotaxime which Citro.koseri lost their resistance to Tetracycline while K. ornithinolytica lost resistance to both antibiotics Tetracycline and Ciprofloxacin either P.mirabilis lost resistance only to tetracyclin as well as Strept.pneumoniae lost their resistance to Cefotaxime, tracycline and Ampicillin. Which may mean that the genes responsible for resistance to these antibiotics are located on plasmids as proven by the results of electrophoresis.Electrophoresis results also showed that all studied bacterial isolates had the same plasmid profile which may regarded as an epidemiological pointer that plasmids are conjugative which have the ability to transfer antibiotic resistance to other bacterial strains of the same species or to other different bacterial species.

Four sites selected along the river whithin three provinces; Babylon, Najaf, Al - Qadisiyah. Assessment of water quality done by using Canadian Council of Ministers of Environment (CCME) and Index of Biological Integrity (IBI) for the purpose of determining the validity and quality of its water for the General purpose and for Drinking and Irrigation.The physicochemical properties and biological (Phytoplankton) were studied during the study period. These properties were; temperature of the air and water, light penetration, electrical conductivity, salinity, turbidity, water current speed, total suspended and dissolved solids, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, carbon dioxide, total alkalinity, acidity, total hardness and ions of calcium, magnesium, sodium, potassium, and the sodium adsorption ratio, chlorides, sulfates, boron, nitrite, nitrate, phosphate, silica and some heavy metals such as cadmium, lead, zinc, copper, chromium, manganese in both phases : dissolved and particulate. results showed that the values of the physical and chemical factors ranged as follows : (7 - 47) C, (10 - 31) C, (14 - 177.5) cm, (1020 - 5600) µs/cm, (0.65 - 3.46) 0%, (0.07 - 129) NTU, (27.03 - 115.57) cm/s, (591 - 2985) mg/L and (0.001 - 0.128) mg/L, (7.04 - 8.8), (6 - 11.8) mg/L, (0.13 - 6.6) mg/L, (8.2 - 53) mg/L, (81.4 - 198) mg/L, (30 - 200) mg/L, (6 - 46) mg/L, (490 - 929.67) mg/L, (83.37 - 290.18) mg/L, (0.79 - 174.84) mg/L, (92.5 - 713) mg/L, (1.9 - 11.18) meq/L, (6 - 133) mg/L, (97.97 - 861.73) mg/L, (329 - 1040) mg/L (0.01 - 4.23) mg/L, (0.008 - 1.33) µg/l, (2.16 - 44.74) µg/L, (0.012 - 0.59) µg/L and (104 - 514) µg/L respectively.Concerning the heavy elements, the values of dissolved cadmium ranged between (undetectable - 0.075 mg/L) and it's particulate between (0.0043 - 0.2705) mg /L and dissolved lead between (undetectable - 0.0232 mg /L) and it's particulate between (0.0045 - 0.148) mg/L and dissolved zinc between (un - detectable - 0.0168 mg/L) and it's particulate between (0.0115 - 0.316 mg/L) and dissolved copper (undetectable - 0.0273 mg/L) and copper is particulate between (0.0062 - 0.063 mg /L) and dissolved chromium between (undetectable - 0.0193 mg/L) and the chromium is particulate between (0.0043 - 0.0449) mg/L and dissolved manganese (undetectable - 0.0256) mg/L and it's particulate between (0.0085 - 0.0739) mg/L.The biological tests include Qualitative and Quantitative Study on phytoplankton and also included calculating the total number of coliform way casting dishes by using the MacConkey Agar media.The number of diagnosed species of Phytoplankton was 295 species, belonging to 74 genera. The Diatoms Bacillariophyceae won the biggest part of it as it formed 160 species and 35 genera any rate (54.24%), followed by green algae (70 species belonging to 24 genera) and green algae (52 species belonging to 11 genera) then Euglenophyceae (10 species belonging to both sexes), while golden brown algae and algae Pyrrophyceae were less algal groups registered as belonging to the two single - sex. Some types of phytoplankton existed in most of the duration of the study, including Bacillaria paxillifera, Cocconies placentula, Cyclotella meneghiniana, Diatoma elongatum, Fragilaria virescence, Melosira ambigua, Synedra acus.The total number of phytoplankton is estimated between (104.9 - 4460.09) cell × 103/liter. An increase in the number of phytoplankton in July and January was observed clearly. The concentrations of chlorophyll - a were ranged between (0.0693 - 9.78 mg /L). While the total number of results for coliform were (5 - 281 × 103) cells/liter, The water quality of the evidence Account (Canadian model) using a number of physical, chemical and Biological properties. The results showed that the waters of the Euphrates are located within categories (Poor - Good) with respect to the public evidence of the quality of water of this river while it was located within categories (Poor - Acceptable) with respect to their use for drinking, While its use for irrigation purposes, it was clear that run river water data fall into two categories (Poor - Good). The results of the analysis of the main components Principal component Analysis (PCA) indicate that the nitrates and the total number of coliform and dissolved oxygen, phosphate, zinc, lead and Biological oxygen demand and pH are the biggest impact on the water quality of the index values of the variables of general purpose.These factors are responsible for the deviation index values, followed by turbidity and total hardness and electrical conductivity and temperature of the water, copper, chromium, and cadmium heat. But with the biggest impact of the index water quality factors for drinking purposes are chloride and electrical conductivity and total hardness, magnesium, turbidity and basal college, sodium, calcium, copper, sulfates, nitrates and coliform, zinc and dissolved oxygen, pH, manganese and lead followed by boron nitrite, cadmium, chromium and vital requirement for oxygen. While the chloride and conductivity electrical, the proportion of sodium, copper, zinc and adsorption of boron have greatest influence on the value of water quality index for irrigation, followed by manganese, cadmium, chromium, lead and pH.The phytoplankton index of Biotic Integrity (P - IBI) has been calculated using ten units including (relative abundance of green algae, green algae, pyrrophyta, Euglenophyta, Xanthophyta, Centralales, pennales, species richness index, the density of phytoplankton and chlorophyll a) The results showed that phytoplankton index of Biotic Integrity values ranging between (47 - 74) in the first position and (47 - 67) in the second location, and (45 - 76) in the third site and (45 - 71) in the fourth site. In other words, phytoplankton index of Biotic Integrity with estimating index (good - poor). The results showed the effectiveness of phytoplankton index of Biotic Integrity values in estimating the environmental changes.

The project was performed in the laboratory of molecular genetics in the collage of education for women, TSB, UCB, BG and ELISA were performed in ATHOP, Assader teaching hospital and Annajaf private laboratory in the period from may to October 2013. Analysis of the UGT1A1 gene expression showed considerable decrease in UGT1A1 expression with relative risk 1.46. Analysis of regression of UGT1A1 mean against severity showed significant inverse correlation between severity of NH and mean UGT1A1 level (r = - 0.99, p = 0.03). Results showed that UGT1A1 expression in males significantly lower than females. Analysis of UGT1A1*28 showed that 80% of the hyperbilirubinemic neonates were positive while 20% were UGT1A1*28 negative. Concluding that there are a considerable proportion of neonates in our community not expressing UGT1A1 enzyme; therefore, they are a risk group for kernicterus. And must be registered and followed up because they are at risk of carcinogenicity, therefore, irinotecan (an anti cancer drug) and similar compounds toxicity. Expression of UGT1A1gene is higher in female than in male neonates, while neonatal jaundice is less severe in female than in male neonates. Eighty percent of jaundiced neonates are UGT1A1*28 mutants. Defective UGT1A1 is the main underlying cause of NJ in our community.

المستخلص: طفيلي المقوس الكونديToxoplasma gondii هو طفيلي ابتدائي اجباري داخل الخلايا ذات النواة. له القابلية على اصابة جميع حيوانات الدم الحار ويعد هذا طفيلي ذو اهمية صحية نظرا لما له من تاثيرات مرضية. لقد اجريت عدة دراسات بينت التغيرات النسيجية التي اثرت على انسجة | Toxoplasma gondii is an a zoonotic, obligate intracellular protozoan parasite that has the capacity to infect all warm - blooded animals. Many studies done to present the histological changes of the placental and fetal tissue and organs that resulted by Toxoplasmosis infection of pregnant women and about identification of infected fetal organs, but a lot of these studies were done experimentally on laboratory animals, accordingly the present study aims to study the structural changes of the placenta and fetal tissue and to identify the fetal organs in which the organism localized that taken from aborted fetus and embryos from pregnant woman that diagnosed as infected with Toxoplasma gondii. The present study was carried out during the period December 2012 to March 2013. Eighty women who had abortion chosen randomly from that which were revised gynecology theater in hospitals in Baquba city. Their age were ranged between 16 - 45 years, (10) fetuses and (33) samples of them non - infected as control group (c) and (37) samples were infected with Toxoplasmosis (I). The study included serological examination for mothers and Macropathlogical (Gross) , histopatholgical examination and Immunohistochimcal (IHC) stain of the placenta and fetal organs. Toxoplasmosis diagnosed serologically by ELISA (Enzyme Linked immune Sorrbant Assay) test. Immuno - histological techniques are used to detect the antigen and determination of their morphological localization in fetal and placental tissue. Formalin fixed paraffin embedded tissues (placenta and specimens of organs from aborted fetus) used to determined the antigen (Toxoplasma gondii) to detect the histological changes in these tissues. The ordinary histopathlogical changes of the tissue taken from aborted fetus showed different infiltration inflammatory cell and necrosis changes in brain, liver, lung, upper and lower limbs, kidney and spleen that may be due to infection of the parasite and not all infected organs localized the parasite (Tachyzoites). The results of the study showed that (46.26%) of the randomly selected mothers among that revised to the delivery theaters and had abortion. The fetal tissue and organs of the age (8 - 24) weeks gave positive (+) result for IHC in fetuses(brain and lung) and tachyzoites was detected in that organs, but fetus tissue of the age (4 - 8) weeks was negative for that test. Macropathlogical study of the placenta showed that the weight of the infected placenta was less than the normal ranges. and calcification was not significant in the infected placenta(45.7%) compared with non infected samples (4.28%). Infarction observed high significant in infected group was 25 (35.71%) compared with control group (2.85%) (p=0.001).Necrotic foci also seen as (40%) in infected group compared with control group (14.28%), differences between the two groups was statistically significant (p=0.001). Also congestion observed high significant (p=0.001) and the congestion was seen in (45.71) in infected group and (5.71%) in control group. Histopathlogical examination for placenta showed hemorrhage, necrosis, fibroniod necrosis and degeneration in trophoblastic cell, in both first and second trimester of pregnancy. Villous vascularity observed decreased as (32.85%) in infected group compared with control group (2.85%). Fibronoid necrosis in villi showed high percentage in villi which have > 3 that observed in infected group as (72.9%) compared with control (12.12%). An increased in villous stromal fibrosis was seen in (70.27%) placenta in infected group compared with control group which was (24.24%)

المستخلص: : توجد هناك عدة عوامل تلعب دور مهم في زيادة الاصابة بطفيلي المشعرات المهبلية وهذه العوامل تتضمن : اختلال مســـــتوى الهرمونات الجنســـــية, تغير الرقم الهيدروجيني للمهبل, بعض انواع الاصابات البكتيرية.الهدف من الدراسة : اولا : تحديد نسب وانواع الاصابات ال | Introduction : It have been founded that many factors play important roles in the increase incidence of infection with Trichomonas vaginalis these factors includes : disturbances in sex hormones level, change in pH of vagina and some types of bacterial infections.Aims : First : To determine the rates and types of Microbial vaginal infections that infected women in Baquba - Diyala province.Second : study of the relationship between the Trichomonas vaginalis and other microorganisms.Third : study the relationship between the Trichomonas vaginalis and the levels of some sex hormones.Patient and Methods : This study was carried out on 227 patients attended either Al - Batol Teaching Hospital for Maternity and Children in Baquba - Diyala, or some private clinic in Baquba city, most of these patient giving symptoms of vaginitis as a patient group, in addition to 10 healthy women as a control group.Patients group included married, widows and divorcees women with age range between (18 - 45) years, and at different educational level.Full clinical evaluation was done for those patient including history and physical examination. This evaluation revealed that 209 of patients (92%) had vaginal discharge, irritation and itching. Reguested blood samples were taken for laboratory test included estradiol, progesterone and testosterone. The level of these sex hormones in women with Trichomoniasis have been determined and compared with levels of these hormones in control group.In addition high vaginal swab were taken for microbiological tests. and used for diagnosis of Trichomonas vaginalis and other associated microorganisms, the rate of parasitic infection had been determined and it's relation with age group, marital status, level of education and level of vaginal acidity had been estimated. Moreover, the percentage of cases, with pus cells, epithelial cells, red blood cells and clue cells have been estimated. Results : the results of laboratory tests elicited the presence of Trichomonas vaginalis (6.3%). And in addition to it there is bacterial and fungal vaginal infection and the percentages were (54%) and (15%), respectively. Moreover, the results showed the presence of dual infections between the parasite and bacteria, the parasite and fungi, and bacteria and fungi and there percentages were (11.8 %), (8 %) and (4.9 %), respectively.Regarding age group, results showed that the highest parasite infection rate was among women in the age group (26 - 35 years) which was (41.1%), in compare with infection rate in others age group (18 - 25 years) and (36 - 45 years) which were (9.3 %) and (18 %), respectively. Regarding, the marited status, the highest infection rate was founded among married women in comparison with widows, divorcees women, and the percentages were (31.7 %), (6.8 %) and (14.7 %), respectively. Regarding, the educational level, the results showed highest rate of infection with Trichomonas vaginalis was among women with low educational level which was (11.8%) in compared with those with intermediate (7.9%), secondary (4.8%), and tertiary education (1.3%). Regarding, the pH of the vagina, results showed that the rate of vaginal infection were high when pH of vagina > 4.5 in comparison with the lowpH ? 4.5 and the percentages were (83.7%) and (16.3%), respectively. The results of direct smear and cultures showed that (25.9 %) of case (59 patient) were infected with Trichomonas vaginalis, (31.7%) of case infected with E.coli, (27.7%) of case infected with candida albicans, (21.1%) infected with Gardnerella vaginalis, (17.6%) percentages of Lactobacillus spp. (8.3%) percentages of Staphylococcus epidermidas (5.2%) in fected with S. aureus, (3.5%) infected with Enterobacter spp., (2.6%) infected with Proteus spp., (2.2%) infected with Klebsiella spp., (1.7%) infected with Acentobacter spp. and Streptococcus spp., (1.3%) infected with Pseudomonas spp., While the lowest rate was for Neisseria gonorrheae (0.8%). Also results showed that the highest percentage of dual infection with trichomoniasis it was in Gardnerella vaginalis which detected in 22 case (37.2%), followed by Candida albicans, which detected in 18 case (30.5%). While the lowest rate was with Neisseria gonorrheae which detected in one case (1.6%). The other laboratory tests including hormonal estimation in patients with trichomoniasis, the results of current study showed decrease level of estradiol hormone in women infected during follicular and luteal phases of the menstrual cycle, In follicular phase the mean of estradiol was (6.83 pg/ml) in comparison with control group that hormone rate was (42.61 pg/ml). In luteal phase the mean of estradiol was (27.00 pg/ml) comparison with control group which hormone rate was (87.16 pg/ml). In addition to that the level of progesterone have increased in follicular phase but decreased in luteal phase in comparison with control group. In follicular phase the mean of progesterone was (5.89 ng/ml) in com - parison with control group which hormone rate was (0.72 ng/ml). In luteal phase the mean of progesterone in infected women was (0.56 ng/ml) comparison with control group in which hormone rate was (19.83 ng/ml).Regarding, the level of testosterone, the results showed that the level had been increased during the follicular and luteal phases in infected women compared with control group. In follicular phase the mean of testosterone was (3.44 ng/ml) in comparison with control group which the mean was (0.24 ng/ml). In luteal phase the mean of testosterone was (3.65 ng/ml) in comparison with control group in which the mean was (0.30 ng/ml).Conclusion : The presence of infection with Trichomonas vaginalis, and it's associated with other microorganisms that are detected in the current study and other study previous may indicated a correlation between them. So those patient, constantly in need for a panel of laboratory test including : vaginal pH, and hormonal estimation as these factors may play a role in diagnosis and follow - up of the patients.

The samples were collected after 3 - 5 day abstinence period at fertility center Laboratories / ALsader Medical city in An Najaf province.For the period from 1/10/2012 to 30/4/2013.Because the studies about varicocele are rare, the present studies aimed to know the impact of varicocele on semen and sperm parameter, sperm quality index, Malondialdehyde concentration and the percentage of sperm DNA integrity.So, this study was aimed at investigation wethere the Varicocelectomy in varicocele patients could positively influence studied parameters.The research was involved examining 83 sample of seminal fluid for varicocele patient. The percentage of varicocele grades were examined and the results were represented 40% grade1, 39% grade2 and 21% grade3.The result were showed a significant decrease (P<0.05) in sperm concentration , progressively motile sperm, normal sperm morphology percent and sperm viability percent for varicocele patient compared with the fertile persons, while there was noticed a significant increase (P<0.05) in Round cells concentration snd liquefaction time for varicocele patient compared to fertile person and the result of this study were showed significant decrease (P<0.05) of sperm quality index and sperm DNA integrity for varicocele patient compared to fertile persons (control).The study noted to the significant increase (P<0.05) of malondialdehyde concentration for varicocele patients compared to fertile persons. The coefficient factor was used to investigate the correlation between malondialdehyde concentration and the studies parameter.there was increase correlation (P<0.05) between malondialdehyde concentration and sperm concentration(r= - 0.86 P<0.05) progressively motile sperm (r= - 0.938), normal sperm morphology percent (r= - 0.90 P<0.05), sperm viability percent (r = - 0.846 P<0.05) and sperm quality index (r = - 0.836 P<0.05), while there was (P<0.05) positive correlation between malondialdehyde concentration and semen volume (r=+0.822 P<0.05), liquefaction time (r = +0.828 P<0.05) and round cells correlation (r= + 0.89 P<0.05).Also the coefficient was used to study the correlation between sperm DNA integrity and other study parameter. The results of this study were showed positive correlation between the percentage of DNA integrity and sperm concentration (r= +0.88 P<0.05), progressively motile sperm (r=+0.78P<0.05), normal sperm morphology (r= +0.86 P<0.05), sperm viability percentage (r=+0.87 P<0.05) and sperm quality index (r= +0.81 P<0.05), while it was noticed in used correlation between sperm DNA integrity and malondialdehyde concentration (r= - 0.681 P<0.05), semen volume (r= - 0.67 P<0.05), liquefaction time (r= - 0.65 P<0.05) and round cells (r= - 0.54 P<0.05). The effect of varicocele grading on sperm and semen parameter, sperm quality index, malondialdehyde concentration and percentage of sperm DNA integrity was studied, the result were showed a significant decrease (P<0.05)of sperm concentration, progressively motile sperm, sperm viability and normal sperm morphology percentage, and a significant increase (P<0.05) of liquefaction time and Round cells concentration for varicocele patients grad1, grade2 and grade3 compared with the fertile persons. and when we are compare between varicocele patient according to type of grade the results were show a significant decrease (P<0.05) of sperm concentration, progressively motile sperm and normal sperm morphology percentage and a significant increase (P<0.05) of liquefaction time for varicocele patients grade2 and grade3 compared to grade1 varicocele patient.So the result showed a significant decrease (P<0.05) of sperm concentration for grade3 varicocele patients compared with the grade2 varicocele patients. The result of this study were showed a significant decrease (P<0.05) in sperm quality index and sperm DNA integrity for grad1, grade2 and grade3 varicocele patients compared to fertile persons. also it was noticed a significant decrease (P<0.05) of sperm quality index and sperm DNA integrity for grade2 and grade3 varicocele patients compared to grade1 varicocele patients but the malondialdehyde concentration according to varicocele grade, the result were showed a significant increase (P<0.05) of malondialdehyde concentration for grade2 and grade3 varicocele patients compared to grade1 varicocele patients and fertile persons. In this study the effect of Varicocelectomy on study parameters was studied and the result were showed a significant increase (P<0.05) of sperm concentration, progressively motile sperm, sperm viability percentage, normal sperm morphology, percent, sperm quality index and sperm DNA integrity and a significant decrease (P<0.05) of liquefaction time and malondialdehyde concentration for Varicocelectomy compared to varicocele patients. The result were showed a significant decrease (P<0.05)of sperm viability percent, normal sperm morphology percent, sperm DNA integrity and sperm quality index and a significant increase (P<0.05) in round cells concentration, liquefaction time and malondialdehyde concentration for Varicocelectomy patients compared to fertile persons.From the result of present study, we are concluded that varicocele has been negatively impact on sperm and semen parameters, malondialdehyde concentration and sperm DNA integrity, and the effect of varicocele is associated with the increasing of varicocele grading, while Varicocelectomy has been positive impact on sperm and semen parameters, malondialdehyde concentration and sperm DNA integrity but this result have not reached to similar state to fertile persons

A total number of Pseudomonas aeruginosa isolates accounted for 89 of 160 samples.The distribution of these isolates were 28 from Burns, 14 wounds, 15 urine, and 32 from hospital environments. Identification of isolates has been accomplished depending on phenotypic diagnostic methods and PCR technique.our study proved that PCR technique depending on oprI and oprL genes was a rapid method for identification of non - pigmented isolates. A total of 20 antibiotics resistant isolates were chosen for Molecular studies. The result reveling that 100% of isolates had a chromosomal mutation in the QRDRs of genes (gyrA, gyrB, parC, and parE). High percentage of isolates(45%) carried mutated genes gyrA and parC, followed by 15% of isolates were carried either mutated gene gyrA alone or three mutated genes gyrA, parC, and parE and and 10%of isolates were carried three muted genes gyrA, gyrB, and parC, while gene that encoding to parC mutation were detected in 5% of isolates. Our study is the first study about detection of Quinolone Resistance Determining Regions in P.aeruginosa in Iraq. The results showed the the presence of mexAB - oprM multidrugs efflux system expression in 100%(20) isolates. while the phenotypic test depending on MIC values for ciprofloxacin alone in the presence of efflux inhibitor showed that only 15%(3) isolates had the active efflux pump.

The age average was (1.36±30.9) , (0.98 ±29.6) and (1.63± 31.4) years respectively. The samples were restricted to the non smoking patients only. The study results show a significant (P< 0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the sperm viability percent and the semen volume, and a significant (P<0.05) increase in the round cell concentration, liquefaction time, Malondialdehyde concentration and the percent of the abnormal chromatin of the Normozoospermic and the Asthenozoospermic patients comparing with the fertile men. The results also show a negative correlation (P<0.05) between the (MDA) concentration and the parameters represented by the sperm concentration, percent of the progressive forward movement sperm, the normal sperm percent, the sperm viability percent sperm quality index and semen volume. While it had been noticed that there was a positive relation between the MDA concentration and the parameters represented by the sperm liquefaction time, round cell concentration and the abnormal sperm chromatin percent of all the study groups. In this research the relation between the sperm chromatin damage and the other study parameters had been studied by dividing the samples according to the degree of chromatin damage. The results show a significant (P<0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the normal sperm percent, the sperm viability percent, the sperm quality index and semen volume, with a significant (P<0.05) increase in the liquefaction time and round cell concentration (MDA) concentration and the percent of the abnormal chromatin of the group (> 10) comparing with the group (? 10) for the fertile men, also the results show a significant (P<0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the normal sperm percent, the sperm viability percent and the semen volume, with a significant (P<0.05) increase in the liquefaction time and round cell concentration for the group (> 25) comparing with the group (? 25) for the infertile Normozoospermic patients. For the Asthenozoospermic patients the study shows a significant (P<0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the normal sperm percent, the sperm quality index, the sperm viability percent and semen volume, and a significant (P<0.05) increase in the liquefaction time and round cell concentration for the study groups represented by the group (> 20 - 40) and (< 40) comparing with (? 20). From the above results it could be concluded that the increase of (MDA) level resulted from the active (ROS) leads to an increase in the abnormal chromatin percent of the infertile Normozoospermic patients which had a negative effect on the semen parameters which could be a reason for the infertility for those patients

المستخلص: يعد السرطان واحدا من المخاطر الاساسية التي تهدد حياة الانسان في مختلف بلدان العالم، لان هذا المرض لا يقف عند عضو معين فهو ينتشر الى كثير من اعضاء الجسم الاخرى ليفتك بها، ومن هذا انطلقت الدراسة الحالية التي اجـريت للفترة من تشرين الاول / 2012 م ولغاية اب | The Cancer is one of highly risk factors that threats the human life world wide, because the disease has metastatic property from primary to secondary sites. This study was carried out during the period extending between October 2012 and August 2013, in laboratories of Faculty of Veterinary Medicine & Faculty of Education for girls in University of Kufa. It is aimed to follow up the changes in volume of growing tumor in female albino mice which were injected with cells of murine mammary adenocarcinoma.The histological changes, immunohistochemical examination investigate the distribution of CD8+ T lymphocytes were also studied.The changes of IgG and IgM titers in serum were also investigated. The study included use of 40 female albino mice at age 6 - 8 weeks, 25g weight average.All mice were injected by cells of murine mammary adenocarcinoman (AM3) in subcutaneous of femoro - dorsal region, and ascending to cervical region. The tumor was successfully implanted into 28 mice.These mice divided into four groups, each contains seven tumor - bearing mice.The animals of the first group subjected to the investigations after 48 hrs from implantation , while those of 2nd, 3rd & 4th groups after 10, 20, 30 days respectively. Seven healthy mice were considered as control group to comparison of immunological tests. Tumor volume & relative tumor volume were measured in different experimental groups. Histological section were prepared by routine histological techniques that including the steps of dehydration, clearing, infiltration, embedding, cutting & staining by hematoxylin and eosin stains, then microscopical examination had been done by optic microscop. The results indicated there was significant increase in tumor volume and relative volume with advancing of tumor age in animals of 2nd, 3rd & 4th groups where compared with first group. The gross examination of the animals of different groups showed that the tumor grew as irregular projection with loss of hair and erosion of overlying skin with milky discharge. The post - mortem examination revealed that the tumor mass was divided into small lobules with various coloures and the tumor mass surrounded by fibrous tissue which increase in thickness as the tumor increased in the age. Extensive areas of necrosis were noticed in the centers of the tumor masses. The microscopic examination of tumor masses in the first group raveled there were sub cataneous small aggregation of tumor cells at the implantation region as well as dispersion of the implantated tumor cells. The inflammatory cells, especially neutrophils were infiltrated. In the second group, the tumor masses showed lobulation by fibrous septa with proliferation of new blood vessels with congestion of them. Infiltaration of inflammatory cells, particularly the lymphocytes. The tumor cells arranged as ribbons and acini, characterized by hyperchromacia pleomorphism, high N/C ratio as well as appearance of mitotic figures. The histological features of the third group revealed increase of amount of fibrous tissue extensive necrotic areas and loss of architecture.These appeared in the fourth group in addition to the presence of cellular debris with dead inflammatory cells. The immunohistochemical study showed no CD8+ T cells were infiltrated in the mass of first group but the little infiltration of these cells was show in the second group. The highest infiltration of the CD8+ T cells was appeared in the third group. while the little cells were discharged in the fourth group. The results of the single radial immunodiffussion assay showed that the implantation with mammary adenocarcinoma had significant effect in increasing the titer of IgM after (48) hours and (30) days from implantation of tumor compared to control group, while the titer is not significant after (10) and (20) days from implantation of the tumor compared to control group. Also the results revealed a significant decrease in the titer of IgG after (48) hours and (30) days from implantation of the tumor, while were no significant increase in the titer of immunoglobulin after (10) and (20) days from implantation of the tumor, compared to the control group. From all the above, We concluded that there was variable histological changes as the age of tumor advanced these changes were characterized by increase of amount of tumor cells in the first groups and occurrence of necrosis in late groups, as well as increase the fibrous tissue as the tumor age advanced. The infiltrative CD+8 lymphocyt was also variable as change of tumor age. The implantation of tumor in mice groups had marked effect in stimulation of humoral immune response through increase of IgM & IgG titers.

المستخلص: هدفت الدراسة الحالية الى الكشف عن دور المورث Erg11 والتعبير الجيني النسبي له في مقاومة خميرة المبيضات البيضاء C.albicans وعلاقته بنشوء عزلات مقاومة او ظاهرة رجوع النمو Trailing growth لهذه الخميرة عند اختبار حساسيتها الدوائية تجاه بعض مضادات الازول (الفلو | The current study aimed to detect the role of Erg11 gene and its relative expression in the resistance of Candida albicans, and its relationship with the emergence of resistace or Trailing growth isolates when tested its susceptibility against azoles agenst (fluconazole, ketoconazole). A total of 120 specimens were collected from patients of both gender with different ages whom infected with oral thrush, uro - genital and Gastrointestinal candidiasis and admitted the General Teaching Hospital and materinaty and children Teaching Hospital in AL - Diwaniyah city during the period from December/2012 to February / 2013. The isolation and identification of yeast isolates were done based on their morphological, Cultural and biochemical tests in addition to use the confirmatory systems such as the growth on Chrom Agar candida, Api Candida and Tobacco Agar medium to distinguish C.albicans from other yeast spp. Also, some virulence factors of C.albicans such germ tube formation, chlamydospores production, growth at of 45 c and resistance to cycloheximide were detected. The antibiotics sensitivity test was used in two method (disk diffusion & dilution) to determine the sensitive, trailing growth, resistance isolates and minimal inhibitory concentration (MICs) toward azole agents. The qRT - PCR was used to detect the relative quantitative of Erg11 gene expression and its relationship with resistance to azole and emergence of trailing growth phenomena in the presence of Fluconazoles and ketoconazole. The isolation and identification results revealed that the isolation percent of C.albicans was 47.05 % incomparison with other Candida species that were 15.3%, 11.76 %, 8.23 % and 5.9 % for C.krusi, C.dubliniensis, C.tropicalis, C. parapsilasis and C.glabrata , respectively. The antibiotic susceptibity tests of C.albicans showed the presence of resistance precent (38.89%) to fluconazole and the most of sensitive isolates revealed a trailing growth phenomena in the zone of growth inhibition of floconazole in a ratio 55.56%. While the resistance percent to ketoconazole was 27.78 % and the sensitive isolates showed the trailing growth in a ratio (38.89%). The statistical analysis showed a significant differences (P <0.05) among tested treatments. The MICs values of fluconazole against C.albicans isolates were 8, 16, and 64 Mg/ml for sensitive isolates and were 0.125 and 0.5 Mg /ml for resistance isolates and the trailing growth phenomena occurred at MICs value ? 8 Mg/ml within 24 hours of incubation while the values became ? 64 Mg/ml after 48 hours of incubation.There was a significant differences (p< 0.05) among tested treatments isolates incubated at 24 hours while there was no significant differences (P>0.05) at 48 hours of incubation. In respect with Ketoconazole, the resistance of C.albicans was increased after 48 hours of incubation at MICs values 0.125, 0.25, 0.5 and 1 Mg /ml while its was sensitive at values 4, 8 and 16 Mg /ml and the trailing growth phenomena occurred when the MICs ? 2 Mg/ml after 24 hrs of incubation, while it reached to ? 8 Mg/ml after 48 hrs of incubation. There was a significant differences (p< 0.05) among tested treatments incubated after 24 hours while there was no significant differences (P >0.05) among treatments after incubation 48 hours. The results of relative quantitative gene expression for both genes revealed a significant differences (p< 0.05) in gene expression levels through the occurrence of increased in the transcription of mRNA quantity among tested treatments.The up - regulation of Erg11 and fold change in mRNA transcription was 2.498 fold compared with 1.0 for control treatment after 24 hrs of incubation in the presence of antifungal, while the increasment was 12.606 fold after 48 hrs of incubation of isolates with antifungals.

المستخلص: تهدف الدراسة الحالية للتعرف على بعض الجوانب الفيزيائية والكيميائية والحياتية لمياه نهر دجلة ضمن مدينة تكريت ولمياه المخلفات السكنية في محطة المعالجة.جمعت العينات لمدة سبعة اشهر اعتبارا من شهر تشرين الثاني 2006 وحتى نهاية شهر ايار 2007 وبمعدل مرتين شهريا | The present study aimed to find out some physical, chemical and biological aspects of Tigris river passed in Tikrit - city, and population residence in the treatment unit.Samples were collected over the period of seven months during November 2006 to the end of May 2007 biweekly. Four stations were selected for sample collections over the distance of 25 km. Two stations were in Tigris river and two were in the treatment unit. The first selected station was close to the old water purification unit in Tikrit - city. The second station was selected at the treatment unit in AL - Dubaee before the mechanical treatment unit. The third station was selected at the treatment unit after the biological treatment. The fourth station was selected in Tigris river about ten km south of the treatment unit at AL - Dijla town. The study involved an investigation of some physical, chemical and biological aspects of Tigris river and the residence waste discharges to the river. This included air and water temperature, conductivity, PH, dissolved oxygen, BOD, Turbidity, total hardness, calcium and magnesium hardness, chloride, total alkalinity, nutrients (i.e., phosphate, nitrite, silica) , and the concentrations of heavy metals (i.e., cadmium and cupper). The biological factor included the total bacteria counts cultured on nutrient agar. Results of the study clarify the close relation between air and water temperature which varied (8.5 - 36) C0 and (9 - 27) C0 respectively. Conductivity values were relatively high and ranged (128 - 3530) microsemens/cm. River water almost was alkaline during the period of the study. PH values of the first and fourth stations were close in the river, although a value of 6.12 was recovered at station on during May. In all stations, PH values ranged (8.8 - 6.12). River water has a good ventilation, dissolved oxygen values ranges (8 - 11) mg/L at the first and the fourth stations, while these values were (0.1 - 1.34) mg/L at the second and third stations. Mean dissolved oxygen values pointed out the availability of good oxygen concentration for the continuity of living organisms which ranged (0.3 - 5.8) mg/L in Tigris river, while BOD values at the stations second and third were high and ranged (5.6 - 131.2) mg/L. Turbidity was high during April at the stations one and four and ranged (2.03 - 788) NTU in all stations. Total hardness in Tigris river was slightly low - very hardness and ranged (120 - 360) mg/L at the first and fourth stations, while these values were (180 - 480) mg/L at stations two and three.The high total hardness values coincided with the high conductivity values. Concentrations of calcium ions responsible on the calcium hardness ranged (211.4 - 120.7) mg/ L was higher than magnesium ions responsible for magnesium hardness range (5 - 265) mg/L.Records of chloride ions ranged (14.16 - 169.99) mg/L at all stations. However, chloride values at stations first and fourth were among the allowed world values and ranged (14.16 - 42.48) mg/L.Alkalinity values were due to the carbonate and bicarbonate and ranged (35 - 725) mg/L.phosphate values ranged (0.168 - 25.2) µg phosphor atom - phosphate/L. Low nutrient values recorded in Tigris river, while the highest values recorded at second station (treatment unit).Nitrite values fluctuated at all stations and ranged (0.078 - 14.778) µg Nitrogen atom - Nitrite /L. Silica values ranged (648 - 5961.6) µg silicon atom - silica /L. Heavy metals values (Cadmium and Cupper) clarify that, Cadmium were (un sensible), except one value (0.008) mg/L that recorded at November, and un sensible for Cupper.Results of the statistical analyses of all involved factors showed significant differences at stations first and second, and between the first and third stations as well as the fourth station. While there was no significant differences between the second and fourth stations. And no significant differences between stations first and fourth.Total bacterial counts indicated high bacterial counts, and the average of total bacterial count ranged (2.605X105, 5.44X108, 2.265X108, 2.385X105) / ml at the four stations respectively, so the Tigris river considered pollutant - very pollutant.

المستخلص: The morphological and histological structure of digestive tract in one species of Iraqi fish that resides in Iraqi inland fresh water (Liza abu) was studied. In this study used (43) fish were in different lengths, the gut of these fish have removed to study the relationship between the length of gastrointestinal tract and the standard body length as well as for morphological and histological study. The value of relative digestive tract length (RGL) was 2.9. Intestine was the longest part of the digestive tract, the average length of intestine was (32 cm). The shape of the folds of the mucous membrane lining the walls of digestive tract showed some differences in different parts of digestive tract, in esophagus the folds were longitudinal running along the wall and it was straight, unbranched and the mean of their number was (9 - 8) folds. In the stomach the folds were longitudinal and (7 - 6) in their number, they were branched into fingerlings structures. In pyloric caeca, anterior and posterior part of intestine and rectum the folds were fingerlings in shape, unbranched and their number were (20 - 19), (27 - 26), (25 - 23), (19 - 18) respectively. Histological study was shown that the wall of the digestive tract is consist of four major coats, from the inside to the outside they were as follows : Tunica Mucosa which characterized by its clear three parts, epithelial tissue, lamina propria and muscularis mucosa. Epithelial tissue in esophagus was thick stratified squamous epithelium, in stomach was thin simple columnar epithelium and gradually increase in length in each of pyloric caeca, intestine and rectum and it was simple columnar epithelial tissue. Mucous which is secreted in esophagus is made of a large proportion of neutral and acidic mucopolysaccharide, while the mucous secreted in the cardiac stomach consist of a large proportion of neutral mucopolysaccharide and less proportion of acidic mucopolysaccharide, either, in the pyloric stomach is consist of very small proportion of both neutral and acidic mucopolysaccharide, in pyloric caeca mucous consist of a small proportion of neutral mucopolysaccharide and less proportion of acidic mucopolysaccharide, and the mucous secreted in an anterior, posterior parts of intestine and rectum consist of small proportion of acidic mucopolysaccharide and large proportion of neutral mucopolysaccharide. Lamina propria consists of connective tissue containing capillaries and lymphoid cells and it represent the basis of the folds, in the cardiac stomach it contains simple tubular glands. Muscularis mucosa characterized by the presence of muscle fibers that are not continuous, the higher thickness of this layer was in pyloric stomach. Tunica Submucosa consists of connective tissue that contains capillaries, the higher thickness of this coat was in the stomach and less thickness of this coat was in the rectum. Tunica Muscularis consists of two layers of smooth muscle fibers, the internal layer has a circular arrangement, the external layer has a longitudinal arrangement in stomach, pyloric caeca, intestine and rectum. either in esophagus tunica muscularis was arranged in inverse manner. The circular and longitudinal muscle fibers in esophagus were skeletal muscle fibers, and they were smooth and non - striated in stomach, pyloric caeca, intestine and rectum. the higher thickness of this coat was in the stomach and less thickness was in the rectum Tunica Serosa is present in all regions of digestive tract.

المستخلص: Cryptic bacterial infection has been studied in urinary system to Human, where 50 underwent urine samples from patient mostly based consulting auditors Hilla public Education Hospital for the period from November 2012 until Feb. 2013. Patients ranged in age from 20 - 50 years males and females bacterial infection rate was 70% distributed between the cell wall defective bacteria had 38% and 32% cell - wall bacteria and the results showed 30% as negative cases. Amicroscopic examination of the urine sludge Showed clear sovereignty of non - specialized immune response type of mixed cell 34% followed by mononuclear cell 30%. Samples were cultured on routine media (Blood agar , Macchonky agar) and Modified media (Variant agar, Variant broth). Out put diagnosed by bacterial system diagnostics, phen - otypic, microscopically and biochemistry by using the special test for microorganism diagnosis and using API 20 E and the use VITEK 2 to confirm some samples results. Characterized by colonies of cell wall defective bacteria grow on variant agar it resembles fried egg which could seen after staining Deinse stain. Citrobacter freundii recorded 12%, the highest rate among cellwall defective isolates. Sensitivity test for bacterial isolates were screened from U.T.I both two type (CWB & CWDB) showed the highest rate of sensitive to Impinem 100% represented CWDB, as well as the highest rate of resistance to Ampicillin 100% represented by the same group of isolates. experimental study with urinary tract infection by injecting bacterial stuck of Citrobacter freundii to the three groups of rabbits : first group ( 3 Rabbits ) : immunized with viable surface antigen extracted from CWDB, second group : ( 3 Rabbits ) immunized with heat killed surface antigen extracted from CWB, the third group (4 Rabbits) represented control group it been treated with sterile normal saline. the injection process through urethra, and then underwent a histological study, was histological damage to the members of the animal - derived non - immunized (control group) seemed clear was the appearance of symptoms of the total cellular infiltration and disruption of the mucous layer and epithelial and other symptoms. The immunized animals have shown their ability to defy injury. It is the study of serological reactions to bacterial antigens Citrobacter freundii immunized with vaccines for rabbits given high caliber agglutination with its specialized vaccines and low with adversity and that the absorption and the corresponding and variant antigen does not remove the agglutination effectiveness with immune sera prepared suggesting that the absorption is incomplete and that the difference between the wall and a wall defective in terms of antigenic is quantitative and qualitative.

المستخلص: The present study was sought to investigate the inhibitory effect of four crude aqueous plant extracts : Zingiber officinale Roscoe (ginger), Camellia sinensis (Green tea), Olea europaea (Olive) and Hibiscus sabdariffa (Rosella) on key enzyme linked to hypertension, Angiontensin - I Converting enzyme (ACE), and on the oxidant/antioxidants status, lipid profile in vitro and in vivo studies. Study of some biochemical biomarker demonstrated that antioxidant enzyme, oxidant enzyme, liped profile and ACE level for 75 hypertension patients. Antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GPx) were shown to have cross relationship with ACE level in hypertension groups, while lipid profile have positive relationship with ACE level in hypertension groups. ACE activity for the four groups G1, G2, G3, G4 were 19.61±3.97, 21.3 ± 1.95, 28.06 ± 5.34 and 32.74±8.19 ng/ml respectively. From these results we concluded that ACE was associated with hypertension and its modulated by drug or herbal extracts. Angiotensin - I Converting enzyme was extracted from sheep lung with specific activity 0.08 U/mg, then the crude ACE extract was concentrated with sucrose by dialysis with specific activity 0.1 U/mg, purification fold was 1.25.The enzyme was purified partly by ion - exchange chromatography using DEAE - cellulose with specific activity 0.5U/mg, yield 30% and purification fold 6.25. ACE activity was determined using N - [3 - (2 - furyl) acryloyl]L - phenylalanyl glycyl glycine (FA - PGG) as a substrate. Results for in vitro ACE inhibitory activity using plant extracts (ginger, green tea, roselle and olive) showed that the all four crude aqueous plant extracts had inhibitory activity in different values when used in the same concentrations about (1 mg/ml), and ginger extract possessed higher inhibitory activity than other three extracts. The ACE inhibitory potency of the ginger extract was found to be significant (P<0.001) when compared with the standard anti - ACE inhibitor drug (Captopril) at the same concentration. The inhibitory activity of ginger extract with different concentration (25, 50, 100 mg/kg) in L - N - ? - nitro - L - arginine methyl ester (L - NAME) induced hypertensive mice was evaluated. Acute oral administration with L - NAME 50mg/kg.b.w causes a rise in blood pressure in normal mice. Administration of aqueous ginger extract (25, 50 and 100 mg/kg) for 4 weeks in L - NAME treated mice significantly (P<0.05) reduced the mean arterial blood pressure compared with L - NAME animals without treatment, with decreasing the serum levels of ACE; while the activity of superoxide dismutase (SOD) and glutathione peroxidase(GPx) showed a significant elevation in ginger treated L - NAME induced hypertensive mice. The results suggest that ginger extract could prevent the development of high blood pressure induced by L - NAME probably can be attributed to prevent or reduce the oxidation process and the inhibition of physiological processes of a substance L - NAME and so as it contains ginger compounds of polyphenols, which inhibits the activity of the ACE and prevent oxidation of fats and repair System Antioxident. Our study concluded that ginger might act as a natural alternative to better and safer in the prevention of negative impacts and risk factors such as high blood pressure and lipids.

المستخلص: SDS - PAGE showed that a single sharp band with an approximately 16.8 KDa molecular weight has been seen. A matter indicates that the enzyme is consistently pure. PCR technique was applied to approve the existence of nuc gene in S.aureus Nevertheless, only those which depicted positive results on DNase agar harboured nuc gene, as it is specified by single band appearance of nuc at assumed molecular weight (ca. 255 pb) of marker that being used. The current study findings highlighted the participation of SNase purified from S. aureus in significant (P< 0.05) preventing biofilm formation by E. coli and K. pneumoniae compared with untreated controls. Evidently, the inhibitory effect of SNase on biofilm formation is undoubtedly perceived, indicating the degradation of the structural major component of biofilm formation (i.e. extracellular DNA). Results revealed that SNase was able to significantly (P< 0.05) reduce the number of the uropathogens; E. coli and K. pneumoniae attached to the uroepithelial cells. 1 Chapter one : Introduction and literature Review 1. Introduction and Literature Review 1.1. Introduction Staphylococcus aureus is a persistent human pathogen that is responsible for a range of diseases that vary widely in clinical presentation and severity. The pathogenesis of S. aureus infection is a complex process involving a diverse array of secreted and surface - associated virulence determinants that are coordinately expressed at different stages of infection (Loughman et al., 2009). Escherichia coli is a genetically diverse species that causes a variety of infections which fulfill many or all of the proposed criteria for biofilmassociated infections (Kaper et al., 2004). Klebsiella pneumoniae is an opportunistic pathogen responsible for a wide range of nosocomial infections. One important factor associated with virulence in K. pneumoniae is its capacity to adhere to surfaces and form biofilms (Cruz et al., 2012). Bacteria often exist as sessile communities called biofilms which are exquisite structures caused by a genetically programmed developmental process. It is estimated that biofilms are involved in 65% of human bacterial infections, since cells in biofilms are 1000 times more resistant than cells in the planktonic state, making medical treatments fail (Shal? et al., 2011). Extracellular DNA (eDNA) plays a significant role in biofilm formation, as revealed by studies in several bacteria including E. coli (Nakao, 2012) and K. pneumoniae (Whitchurch et al., 2002); however, there is no definite proof on a cause - and - effect relationship between DNA release and biofilm formation (Beenken et al., 2012) or becomes a key component of the macromolecular scaffold in many different biofilms (Jakubovics et al., 2013). In rare cases eDNA has been shown to inhibit bacterial settlement. Therefore, it is possible that nuclease mediated eDNA degradation would therefore promote adhesion. Consequently, it is not clear whether microbial nucleases contribute to the gross biofilm structure in clinically relevant situations (Sheilds et al., 2013). 2 Chapter one : Introduction and literature Review All previous studies used both commercial bovine and recombinant human DNaseI in the disruption of medically important biofilms; whilst, extracellular nuclease of S. aureus (SNase) was used against biofilm of S. aureus themselves (Benenken et al., 2012b ; Kiedrowski et al., 2014). Thus, to date, the role of S. aureus exonucleases in biofilm of other bacteria remains unclear. However, in the present study SNase is used against biofilm of other bacterial species (viz. K. pneumoniae and E. coli). To address this, the following steps were undertaken : 1 - Investigating the negative impact of SNase extracted from S. aureus on K. pneumoniae and E.coli biofilm formation. 2 - Studying the preventive activity of SNase on the adherence of K. pneumoniae and E. coli on uroepithelial cell.
