المستخلص: تم استخدام حسابات ميكانيك الكم التقريبية شبه التجريبية وفق نموذج الحساب PM3)) وحسابات ميكانيك الكم الاساسية التامة غير التقريبية وفق نظرية دوال الكثافة (DFT) وباسلوب B3LYP وعناصر قاعدة 6 - 311G لحساب جزيئة الفلرين التي امتلكت التماثل Ih مع وحدات بناءها (5 | Semi - empirical quantum mechanical methods (PM3) and Density Functional theory calculations (DFT/ B3LYP/ 6 - 311G) were executed to evaluate the fullerene molecule ,the internal coordinates (bond length and angles) and some physical and energetic properties.Calculations of the geometrical Parameters (bond lengths and bond angles), have shown that the (C=C) bond length is increased with increasing the size of the molecule that increased elasticity especially to fullerene to be like a ball. The (C - C) bond length is decreased with increasing the size of molecule, that means fullerene will be more stable than the other molecules.The energetic values (heat of formation) is found to be increased with the increasing of the size of molecule. The total energy is decreased with increasing size of molecule that means the stability will increase with the increasing of the size of unit construction of fullerene molecule , on the other hand , the energetic difference (E HOMO - LUMO) between the higher level of orbital and the lower level of orbital are decreased with the increasing of the size of molecule ' unit construction reaching to the fullerene molecule. So, this property will increase the significance of fullerene in the industrial and the electrical purposes.The vibrational modes frequencies with ( 3N - 6) whereas N is represented by number of molecule atoms which are evaluated with the absorption intensities of infrared frequencies. symmetrical and coordinated modes were discussed at the equilibrium geometric formation by using the programs MOPAC & Gaussian 05.It is worthy to say that it was not mentioned before that the complementary classification for the vibrated motion modes for such molecules , so our evaluations may considered unique. It is noted , as well , that CH stretching frequency has had fluctuations that means increasing and decreasing in the values of frequencies. In connected with the bending vibrated modes which taking place out of plane of the molecule are decreased with the increasing size of the unit constructions of molecule but it is increased only at the fullerene molecule. Conversely, the bending vibrated modes which are taken place in the plane of molecule are increased with the increasing the size of unit construction of molecule but are decreased at the fullerene molecule.The distribution of the electronic charges density on the atoms of unit construction of fullerene molecule were studied, the results shown the absence of the electronic charge on the atoms of Fullerene molecule and its concentrated at atoms of the outer circumferential edges C - Cc for the aromatic rings in its own unit construction. Semi - empirical methods (PM3) and Density Functional theory calculations (DFT/ B3LYP/ 6 - 311G) were carried out to evaluate the vibration frequencies and infra - red (IR) absorption intensities for equilibrium geometries of construction units of (6,0) zigzag (Mono (D6h), Di (D6d), Tri(D6h), Tetra (D6d)) ring layers SWCNTs and the internal coordinates ( bond length & angles ) at the equilibrium geometric formation symmetrically according to group theory were evaluated. The most important notes were axial bond length C - Ca which is decreased with the increasing of the tube length whether odd or even number of ring layers. The length of these mentioned axial bonds will be longer in the outer layers than the middle layers that means the increasing of stability of the tube with its length increasing , with the ability of replacing the external atoms of the tube because they are connected with longer and weaker bonds. The reverse was found with the circumferential bond lengths C - Cc was as they were increased with the increasing length of the tube whether the tube was odd or even in number of ring layers. Moreover , the lengths of these bonds are decreased in the middle side to the outer one for the odd and even ring layers. This will confirm the stability of the tube with its length increasing. The lengths of outer bonds C - H which are situated on the edges of the tube which were approximately fixed , with exception of the bond length of CH bonds in Mono ring layers which were longer because the large negative charge on carbon to which it is bonded and the large positive charge on it compared with the positive charge on hydrogen atoms of the multi - layers tubes. The heat of formation which was found to be increased with the increasing of the length of the tube , that means increasing of the stability and the aromatic properties , with the increasing of number of tube' layers. This property will increase the importance in the uses of these tubes for the industrial and electrical purposes as semi - conductors.The vibrational modes frequencies with 3N - 6 with the absorption intensities of infrared frequencies were evaluated and classified. These modes were discussed in symmetrical and coordinating manners at the equilibrium geometric formation, by using the programs of MOPAC and Gaussian 05 , with confirming on unavailability of bounded specification for such modes with 3N - 6 in the literature. We have a through our studies that the stretching vibration modes of symmetric and anti - symmetric Carbon - Carbon axial bond (C - Ca) increased with the increasing length of tube , and this will increase the physical properties for electrical conductivity with confirming on the significance of nanotube industrially. For the vibrational bending frequencies which are taking place in plane and out of plane of molecule surface as well as the vibrational stretching for odd number of ring layers (Mono and Tri) fluctuation will be happening in the relations , as all of them will be decreased with the increasing of tube ' length except (C - Caasym, C - Casym , ? CHsciss. , ? ringasym , ? ringsym and ? ringsym ) which be increased with the increasing the length of tube. The vibrational bending frequencies which are taking place in plane and out of plane of molecule surface for the even number of ring layers ( Di and Tetra layers ) will be decreased with the increasing of tube' length except (? CHsciss.) which is increased with the increasing of tube' length. Furthermore , all vibrational modes which are related to the puckering , breathing and bending movements of clockwise and anti - clockwise according to "group theory" were determined in accurate manner to which deformations are related , which are happened in the tubes , as a result of vibration, that may prevent the flow of electrons' movements and their transitions. The numerical values for the vibrational frequencies which are resulted from Semi - empirical methods (PM3) were acceptable in comparing with the strict calculations , hopping to achieve best values and to be close to the values obtained for the strict calculations (DFT) method to be suited with the basis and standards that are depended internationally. Some of these values were corrected by multiplied by constant scaling factors for such molecules. The results of scaling were good and very close to the experimental and calculated values.The distribution of charges' density on units of construction atoms of (6,0) zigzag nanotube SWCNTs also were studied. The results were consistent with the physical and experimental conductivity properties for such calculated tubes , as the intensity of the electronic charge was concentrated on the outer circumferential edges of atoms C - Cc for the aromatic molecules as well as for nanotubes with its disappearing form outer side towards the middle side of multi - ring layers ( Mono , Di , Tri and Tetra ).

المستخلص: There are a wide variety of polyphenolic compounds named flavonids. These are extensively distributed in plants, and they are considered to be dietary antioxidants. They occur naturally in broad range of vegetables, fruits, and primarily recognized as the pigments.Many flavonoids have a metallic ion complexation capacity. The study of this capacity is important because it can be used in producing nutritional supplements, medicine, and heavy metal detoxification.Chelation therapy is the use of chelating agents (complexing agents) to detoxify poisonous metal such as mercury, arsenic, and lead by converting them to chemically inert form that can be excreted without further interaction with the body.Lead is considered as one of the most hazards and cumulative environmental pollutants that affect all biological system through exposure from air, water and food sources. It is toxic heavy metals which are known to induce a broad range of physiological, biochemical and behavioral dysfunction in humans. Because of its perverseness in the environment, lead poisoning still remains an important health problem.The polarographic measurements were carried out using differential pulse polarography (DPP), at hanging mercury drop electrode (HMDE) at the optimal conditions for flavonoids which were 1M HCl for Quercetin, Rutin, and Hespertin and 0.01M NaOH for chrysin as a supporting electrolyte.A well - defined two electron reversible reduction and diffusion controlled one wave for these flavonoide were observed, a linear relationship between concentration and diffusion current (id) was obtained with the value of correlation coefficient (r2) near to one, this obey Ilkovic equation. The values of n; the number of electrons transferred in the reduction process were obtained from the slop of the straight line corresponding to E vs. log i/id - i.Addition of flavonoides to a solution of Pb (II) ion, show the appearance of a new peak in a more negative potential than Pb (II) peak, with the gradual decrease in id of Pb (II) ion which suggests the complex formation between them.The stoichiometry and the stability constant of Pb (II) complex with flavonoids were calculated by Lingane equation; a plot of ?Ep vs. log [L] give a straight line, the slope of the line allows the determination of the coordination number (p), and the stability constant were determined from the intercept, the stoichiometry of these complexes were (1 : 1) with a stability constant of : Pb - Quercetine (5.5*107) ? Pb - Rutine (1.3*107) ? Pb - Hespertine (4*106) ? Pb - Chrysin (5.4*104)These measurements also includes the determination of the kinetic parameter of the electrode reaction (Kth, ?n) and the thermodynamic parameters such as ?H, ?G, and ?S.The spectrophotometric measurements were carried out in 50% methanol/water for Quercetin and Rutin, 30% methanol/water for Hespertin and in phosphate buffer of pH - 7 for Chrysin.The electronic spectrum of free flavonoides in methanol solution was mainly characterized by an important absorption band at ? 370 nm (band I) and a second one located at ? 256 nm (band II). Upon addition of lead (II) to the flavonoids solution significant changes are observed in the electronic spectra, a bathochromic shift in band (I) to the extent of ? 40 nm and a shift in band (II) to the extent of ? 7 nm, the change in ?max and the change in the intensities of the bands were due to the coordination between flavonoids molecules and Pb (II) ion.The stoichiometry of the formed complexes were investigated by the method of continuous variation and it were found (1 : 1), the stability constant were calculated also and were found to be in the order of ? 105 to 106.Thermodynamic parameters and kinetic studies were also determined which indicates a second order interaction between lead (II) and these flavonoides.Spectroscopic measurements for (EDTA) Complexation with lead (II) were carried out in order to compare its stability constant with that obtained for flavonoides complexes, due to its application in the treatment of metal poisoning.Stability constant of (EDTA) with Pb (II) complex were in the order of 108 which is much more efficient than flavonoides.

المستخلص: Two field experiments, several greenhouse and laboratory experiments were conducted during the course of study to evaluate the allelopathic potential of two sunflower (Helianthus annuus L.) cultivars on companion weeds and weeds grown in mungbean (Vigna radiata L. R. Wilczek) field alone and in combination with reduced rate herbicide, and to determine the chemical and genetical bases of allelopathic traits in the test cultivars. The aim of the first experiment was to test whether the variation in weed growth between the sunflower cultivars (Shumoose and Sin Altheeb), which was observed in the field, was due to differences in their allelopathic potential. Results showed the ability of both cultivars to reduce weed population and biomass with the superiority of Shumoose cultivar in suppression of weed density at 60 and 120 days after sowing compared to Sin Altheeb. Weed biomass was significantly reduced up to 90 and 71% by Shumoose and Sin Altheeb cultivars, respectively. Stair case experiment indicated that root exudates of Shumoose cultivar showed more suppression to weeds than Sin Altheeb giving additional evidence for the superiority of Shumoose cultivar in its allelopathic weed suppression. Chemical analysis by High performance liquid chromatography indicated the presence of 9 compounds in root exudates of Sin Altheeb and 8 compounds in Shumoose, and all are Phenolic in nature. However, total of the isolated phenolics was doubled in Shumoose than in Sin Altheeb. Most of the isolated chemicals are reported to have inhibiting ability for germination and growth of plants, including weeds. Second field experiment was undertaken to explore the response of weeds and mungbean crop to soil incorporated with sunflower residues in combination with lower rate of a pre - plant herbicide (trifluralin). Sunflower residues of the two cultivars Shumoose and Sin Altheeb at 3.2 and 6.4 t ha - 1 were used either alone or in combination with trifluralin at 1.2 L ha - 1 (50% of label rate). Weedy check (control), trifluralin at full label rate (2.4 L ha - 1), and weed free treatments were also included for comparison. Plots treated with 50% of label rate of herbicide and amended with sunflower residues of cultivar Sin Altheeb recorded least weed density and dry biomass and this suppression was much greater than the residue treatments alone and more than cultivar Shumoose. Application of herbicide at 50% rate in plots amended with Sin Altheeb residue resulted yield 64 % more than with the label rate of herbicide treatment. Chromatographic analysis of sunflower amended field soil revealed the presence of several potent allelopathic compounds in the residues of both cultivars with greater quantity (355.5 µg/ml) in Sin Altheeb than in Shumoose (250.9 µg/ml). Dynamics of release, decomposition and degradation of allelochemicals into the soil showed that different compounds exhibited differential behavior for these processes. Overall quantity of allelochemicals started to increase after 2 weeks of decomposition and peaked at 4 week of decomposition (180.1 ppm) then declined sharply in their quantities thereafter. Periods indicating higher quantities of total phenolics as shown by chromatographic analysis was coincided with the periods in which higher suppressive activity against weeds grown under field conditions. Bioassay of sunflower residues decomposed in soil at different times on Echinochloa colonum L, one of the weeds dominated the mungbean field, revealed that residues of both cultivars suppressed growth of E. colonum weed. The phytotoxicity started after 2 weeks and persisted for 8 weeks. However, Sin Altheeb residues showed greater inhibition than Shumoose cultivar at the last three decomposition periods. Shumoose residues recorded appreciable reduction to the growth of test weed compared to Sin Altheeb. The effect of residues of both cultivars on chlorophyll content and ions uptake in Amaranthus retroflexus L. weed revealed that residues of both species reduced chlorophyll content of leaves and the reduction increased with the increased residue rate. Sin Altheeb cultivar residues were more inhibitory than Shumoose at the lower residue rate. In the same weed, ions uptake was significantly averted by the residues of both cultivars. P and K was significantly increased over control, while Ca, Mg an Fe were found to be decreased over control due to application of sunflower residues in soil at 8 g per kg soil. N was the only test element that did not significantly influence by the residue treatments. No significant differences were found in the test ion uptake between the test sunflower cultivars. Results of using RAPD technique on the sunflower genomic DNA revealed that all the 19 primers used in this study scored different amplification monomorphic and polymorphic bands in the tested genotypes with 12 primers generated polymorphic bands. These bands present in one cultivar and absent in another. They could be responsible for allelopathic trait or secondary compounds associated with this phenomenon. Further work is recommended to analyze the sequence of this band to find out whether it is related to allelopathic trait or not.

المستخلص: شملت الدراسة 63 مريضا مصابا بداء السكري غير المناعي المنشا في اعمار مبكرة من ذوي التاريخ العائلي بالاصابة بمرض السكري ممن لايعانون البدانة الذين تم اختيارهم من مرضى السكري من مراجعي المركز التخصصي لامراض الغدد الصم والسكري في الرصافة/ بغداد للفترة من ايار | This study included 63 non obese patients having early onset of non immunogenic diabetes with strong family history of diabetes selected from diabetic patients attended the specialized center of endocrinology and diabetes at Alrusafa/ Baghdad during period from the begging of May 2011 till the end of February 2013. The demographic study revealed that there is no association between the disease incidence with neither the gender nor the blood group. But there is a significant difference in the distribution of the patients according to age of the first diagnosis and gender, as the study showed that majority of male patients (53.846%) were first diagnosed with hyperglycemia below the age of 20 while the majority of females (72.972%) were first diagnosed with hyperglycemia after the age of 20.The distribution of patients according to the type of treatment also reveled association between the gender and both age of diagnosis and type of treatment of the hyperglycemia as the study showed that there is a higher percent of male patients (80.768%) using insulin at the beginning of their diagnosis with hyperglycemia or transferred later to insulin than those of females (67.565%).The present study reported for the first time in Iraq the presence of monogenic diabetes (maturity onset diabetes of the young type 3) as major cause of diabetes within non obese diabetic patients' early onset of non immunogenic diabetes with strong family history of diabetes. The sequence analysis of the hepatocyte nuclear factor 1? gene showed that Iraqis have mutational hot spot at exons 3 and 4 of this gene responsible for maturity onset diabetes of the young type 3, and that mutations in the promoter region or exons 5, 6, 8 and 9 are a rare cause of diabetes.

المستخلص: داء السكري مرض واسع الانتشارعالميا تختلف نسبة الاصابة بين البلدان المتطورة والنامية ويعتبر المسبب الرئيسي للاعاقة والموت في العالم.داء السكري النوع الثاني هو الاكثر حدوثا حيث تبلغ نسبة الاصابة (90 - 95%) من مجموع المصابين بالسكري للانواع الثلاثة الرئيسية. | Sixty of non insulin dependent diabetes mellitus (NIDDM) patients who were diagnosed according to American Diabetes Association criteria (ADA) 2007 were selected from the specialized center of endocrinology and diabetes (Baghdad AL - Russafa Health Directorate) during the period between first of May 2013 to last of October 2013.Their age ranged 35 - 70 years. Fourty apparently healthy individuals their age ranged (35 - 70) years were considered as control. Enzymatic colorimetric methods used for measured FBS (fasting blood sugar) and HbA1c (glycohemoglobin) and enzyme linked immunosorbent assay (ELISA) for hormones and enzyme markers. Fasting blood sugar revealed high significant in patients with median (11.6 mmol/L vs. 5.9 mmol/L) and (P<0.001) in comparison to control groups.Elevation of glycated hemoglobin (HbA1c) with mean (9% vs. 5.5%) in comparison to control groups. Another reliable marker are the concentration Adpionectine hormone, Insulin hormone and adenosine deaminase activity the results of those estimated significantly difference between levels mean (20.7 vs. 34 ng /ml) in patients compared to healthy subjects (P<0.001) for adiponectin ; mean (106.6 vs. 59.3 ng/ml) for ADA (adenosine deaminase) with (P<0.001) and the median (12.1 vs. 16 uIU/ml) for insulin hormone with (P 0.001). In order to investigate the accuracy of previously mentioned tests, a statistical analysis [Receiver - Operator Characteristics (ROC)] has been applied to show the accuracy, specificity and sensitivity of the tests under test.This analysis revealed that serum ADA activity is the best marker with highly specificity 100%, sensitivity 100%, and accuracy 100% while; FBS was the best test with highly specificity 100%, sensitivity 100% and 100% accuracy in comparison with other tests. It was denoted that type2 DM was associated with certain HLA class II alleles were analyzed for their genotyping by Polymerase Chain Reaction - Sequences Specific Olegionucleotide (PCR - SSO) technique. The present study revealed that diabetic patients were positively associated with HLA - DQB1*0201 (83% vs. 5.0%) which is the most prevalent in patients followed by DRB1*1137 (46.7% vs. 0.0%); DRB1*0401 (41.7% vs. 2.5%), and DRB1*1306(15% vs.0.0%) while HLA, A*0201;B*3559;Cw*0410 and DQB1*0501 is negatively associated in type 2DM in comparison with healthy control groups.This study has shown that there is no significant association between FBS, HbA1c, serum insulin, HOMA2(Homeostatic Model Assessment2) ? - function, HOMA2 - IR, serum adiponectin, serum ADA and HLA alleles(DQB1*0201, DRB1*1137, DRB1*0401, DQB1*0501, DRB1*1306) in spite the significant associated between FBS and serum ADA and HLA - DRB1*0701 allele with (P 0.021, P 0.008) respectively.The current result concluded that there may be an important role for HLA genotyping in arising the chance for enhancing the susceptibility for either disease development or protection against its initiation.

The number of scabietic patients who attended the outpatient clinic during February to November 2012 were 300 (168 males and 132 females). Their ages ranged from 10 to 65 years. They were included to show the prevalence of scabies. Sixty scabietic patients (out of 300 patients) who did not have allergic diseases, helminthic infections, previous attack with scabies, and/or getting any antihistamines drugs were included for human IL - 1?, TNF - ?, IL - 4, IL - 5 and total IgE assays using ELISA technique; superoxide dismutase (SOD) activity assay and eosinophils(%). These assays were applied on scabietic patients (who were divided according to onset of symptoms or duration of scabies symptoms into early and late scabietic patients) as well as healthy controls.Also Sarcoptes scabiei mite proteins were extracted. Then heat stable mite proteins concentration was determined by Bradford’s method. SDS - Polyacrylamide Gel Electrophoresis (SDS - PAGE) analysis was used. The activity of mite allergens was assayed by skin prick test (SPT) in 10 scabietic patients and 5 controls with 1.2 ?g/ml and 2.4 ?g/ml. House dust mite (HDM) antigens were skin prick tested in patients with scabies and controls.The prevalence of scabies in current study constituted 6.54% from all the dermatoses which attended the clinic. The males represented 56% and females were 44%. The age group (10 - 19) years was the highest prevalence of scabies (41.7%). Early scabietic patients represented 72% versus late scabietic patients were 28%. The results revealed that a highly significant elevation (p< 0.001) in serum cytokines (IL - 1?, TNF - ?, IL - 4 and IL - 5) as well as IgE, SOD and eosinophils (%) in the two groups of scabietic patients in comparison to the controls.Results of correlation demonstrated that IgE, SOD and eosinophils (%) were positively and significantly correlated (p< 0.001) with the studied cytokines in early, late scabietic and control groups. IgE was positively correlated with IL - 1?, TNF - ?, IL - 4 and IL - 5 in early scabietic patients, whereas, it had negative correlation with IL - 1?, TNF - ?, and positive correlation with IL - 4 and IL - 5 in late ones. SOD showed negative correlation with IL - 1? and TNF - ?, and positive correlation appeared with IL - 4 and IL - 5 in both scabietic patients. Eosinophils (%) were positively correlated with all the studied cytokines in two groups of scabietic patients.The results also revealed that SDS - PAGE profile of the parasite heat stable proteins consisted of protein bands with molecular weights ranged from less than 10 to over than 100 kDa. Skin test demonstrated that (7/10, 70%) and (8/10, 80%) of scabietic patients had a positivity against 1.2 ?g/ml and 2.4 ?g/ml of sarcoptic mite extracts, respectively when prick tested. HDM extract was found to be positive in (4/10, 40%) of scabietic patients; while controls revealed negative result.It can be concluded that scabies affect TH1 and TH2 immune response as well as SOD activity and eosinophils. Sarcoptic proteins contain heat stable allergens which able to cause immediate type - 1 hypersensitivity when 1.2?g/ml of mite protein is skin prick tested, and there is a cross reactivity between Sarcoptes scabiei and HDM allergens

المستخلص: The present study aims to shed light on the follow up of acute leukemic (AL) patients at initial diagnosis and after treatment to assess the response and early relapse through evaluating the gene expression level of one of the major multidrug resistance genes which is the multidrug resistance 1 (MDR1) to investigate the possible association between level of MDR1 gene expression and the clinical outcomes and this may be considered as a potential marker for response to chemotherapy of acute leukemic patients. Furthermore, the current study correlates between the MDR1 gene phenotype and MDR1 genotype in three important coding regions (C1236T, G2677T/A, and C3435T considering the potential influence of altering MDR1 activity and its effect on therapy outcome as well as susceptibility to develop cancer.White blood cells (WBCs) isolated from 106 blood sample of acute leukemic patients were provided by Iraqi hospitals in Medical City. These samples were distributed as follows : 46 newly diagnosed patients with acute leukemia who had not received chemotherapy and follow - up 25 after 1st induction, 17 after 2nd induction and 8 at consolidation, with 10 blood samples of healthy voluntaries. Two comparative groups were taken included 46 sample of peripheral blood (PB) and 26 sample of bone marrow biopsy (BMB) in paraffin blocks to validate the level of gene expression compare to WBCs. For genotyping analysis, 56 of blood sample were taken to study genetic variation of MDR1 gene polymorphism. The samples preservation with TRIzol was done. Samples subjected to total RNA and DNA extraction, then molecular study by using reverse transcription, Quantitative Real Time - polymerase chain reaction (qRT - PCR) and direct sequencing, at Molecular Oncology Unit in Guy´s Hospital - Kings College / London.The study reached at the following results : 1 - The results showed age groups (20 - 39 years) were associated with acute myeloid leukemia (AML), while (13 - 19 years) with acute lymphoblastic leukemia (ALL).2 - The level of MDR1 gene expression showed high significant differences with WBCs compared to PB and BMB.3 - The clinical outcomes indicated that the rate of complete response (CR) of newly diagnosed acute leukemic patients was 19(41%), while 27(58.7%) was non - responder (NR).4 - Statistical analysis showed significant differences with NR at initial diagnosis in acute myeloid leukemia, while appeared after 1st induction in lymphoid type.5 - The results of positivity MDR1 gene expression were 10(21.7%) out of 46 newly diagnosed in acute leukemia, while 36(78.3%) were MDR1 - negative depend on (1.1±0.03) cutoff value.6 - The positivity MDR1 gene expression appeared mainly in non - responders patients at initial diagnosis, and with early relapse patients, after complete remission, in consolidation.7 - The MDR1 mRNA expression showed significant differences with high level in NR compared to CR patients at initial diagnosis. During treatment follow up the increased level of MDR1 gene expression in CR patients and appeared non - significantly with NR.8 - The results of MDR1 C1236T genotype and allele frequency showed that 1236CC wild type genotype and C allele were significantly frequent in healthy control. While CT heterozygous genotype frequency was highly significant in AML and no significant difference in allele frequency. ALL showed non - significant difference in genotype and allele frequency of MDR1 C1236T.9 - Odds ratio and 95% confidence interval (ORs and 95%CI) analysis showed no evidence associated with risk factor in MDR1 C1236T ALL carriers. While risk factor observed in AML with MDR1 1236CT carriers.10 - The results of MDR1 phenotype - genotype association indicate that MDR1 1236CC wild type was significantly high expression among healthy and it was aprotective genotype. While the MDR1 1236CT showed significant differences with high level of MDR1 gene expression in AML patients. Whereas ALL revealed significant differences in high level of MDR1 gene expression with MDR1 1236TT genotype. Both CT and TT were affected genotypes.11 - The results of MDR1 G2677T genotype and allele frequency indicated that 2677GA genotype significantly appeared with low frequency in healthy control with no significant difference in allele frequency. Both ALL and AML showed high significant frequency in 2677GT genotype. G allele frequency was showed significant differences in AML while non - significant in with ALL.12 - Odds ratio and 95% confidence interval (ORs and 95%CI) analysis showed the MDR1 2677GT genotype was associated with risk factor to developing ALL and AML. Whereas the GG appeared associated with AML only.13 - MDR1 phenotype - genotype association, indicate that MDR1 2677GA genotype was significantly high expression in healthy individual. While AML patients showed significant differences with high level of MDR1gene expression in 2677GT genotype. ALL showed significant differences with high level of MDR1 gene expression in MDR1 2677TT genotype.14 - The results of MDR1 C3435T genotype and allele frequency showed significant difference in genotype and allele frequency with heterozygous CT in both control and AML patients and mutant T allele. Whereas non - significant genotype and allele frequency with ALL.15 - Odds ratio and 95% confidence interval (ORs and 95%CI) analysis showed that the MDR1 3435CC genotype carriers associated with risk to developing ALL. While no risk factor associate with MDR1 C3435T variants to develop AML.16 - MDR1 phenotype - genotype association, indicate that the wild type 3435CC genotype was significantly high expression in healthy control. The MDR1 3453CT genotype showed high significance with high level of MDR1 gene expression inAML. While ALL showed significantly high level of MDR1 gene expression in 3435TT genotype.17 - The results of MDR1 genotype - phenotype association showed similar impact of MDR1C1236T, G2677T/A and C3435T genotypes in AML clinical outcomes. The MDR1 CT/GT/TT genotypes were associated in NR AML with high level of expression at presentation, compared to significant low level in CC/GG genotype. In contrast, CR patients were observed non - significant with MDR1 gene expression at presentation and significant with low MDR1CC/GG genotypes in post treatment. In regards to ALL patients the MDR1 TT genotype showed significant differences with high level of MDR1 gene expression in NR and CR ALL at presentation and significant only with NR at post treatment. So there was no clear evidence between MDR1 genotypes and clinical outcome with ALL.18 - The haplotype results showed that the three MDR1 C1236T, G2677T/A and C3435T genotype were linkage disequilibrium significantly with heterozygous haplotype B (CT - GT - CT) compared to A(CGC) and C(TTT). Also B haplotype appeared significantly with high level of MDR1 gene expression compared to A and C. According to the clinical outcome, haplotype B was observed significant differences in NR AML patients while other haplotypes were non - significant

A total of 800 of urine samples were taken from patient suffering from urinary tract infections had been collected during a period from February, to September of 2012, from the hospitals of AL - Najaf province. All the samples were cultured on MacConkey agar. From those 300 samples gave positive bacterial growth , 250 were lactose fermentative isolates, which were submitted to conventional tests including IMVIC and motility tests ultimately lactose fermentative, non motile isolates were candidate to Vitek 2 system to confirm the identification. the results revealed that there were 42 (16.8%) of isolates identified as Klebsiellae represented by Klebsiella pnumoniae ssp pneumoniae, 9(3.6%) of isolates diagnosed as Raoultella ornithinolytica, and 1(0.4%) for both K. pnumoniae ssp.ozeanae and Raoultella planticola. Screening tests were performed , disk diffusion test revealed different pattern of resistance, screening of ESBLS by MacConkey agar medium supplemented with 2 mg /l of Ceftazidime showed that 31 (58.5%) of isolates were initially ESBLS producers.Phenotypes confirmatory tests were conducted to different classes of antimicrobial agents, Disk synergism test revealed that 20(37.74%) of isolates were ESBLS positive, while Disk combination test by Ceftazidime + clav and Cefepime + clav revealed that 28(52.83%) and 43(81.13%) were ESBLS producers respectively, disk replacement test pointed that positive isolates were 26(49%), vitek2 system revealed 33(62%) of isolates were ESBLS producers.Imipenem - Ceftazidime antagonism test revealed that there was no isolate produce induced AmpC beta - lactamase, AmpC disc test revealed that no one of isolates were AmpC producer.The result of MHT(Modified Hodge test) revealed that all isolates were not Carbapenemases producers. Molecular study of different antimicrobial resistance genes were performed, the results reveald high percent of occurence as follow : blaTEM genes (90.6%), blaSHV gene(81.13%), blaCTX - M genes (88.6%), sul genes (88.6%), aac(6')Ib - cr genes (84.9%) and qnr - B genes (41.5%).the study also highlighted an association between studied genes. Finally many attempts to study of gene transfer by conjugation were conducted but all of them were failed, except one isolate (No. 5) was succeeded with frequency of conjugation (0.5×10 - 7). This study concluded that there were high prevalence of some plasmid mediated genes of isolates with clear multi gene resistance patterns as compared with some other genes which propose the high selective pressure of these genes and isolates might acquired resistance by mobile elements such as plasmids and integrons.

المستخلص: قدر التنوع الوراثي لـ 19 من الانماط الوراثية للطماطة (المحدودة وغير المحدودة النمو) المستزرعة في العراق باستخدام اثنين من واسمات الدنا (DNA Markers) المعتمدة على تفاعلات البلمرة المتسلسلة Polymerase Chain Reaction (PCR) وهما واسمات التفاعل التضاعفي العشوا | Genetic diversity of 19 tomato genotypes (determinate and indeterminate) cultivated in Iraq using two polymerase chain reaction based DNA markers (PCR based DNA markers); Random Amplified Polymorphic DNA (RAPDs) and Simple Sequence Repeats (SSRs).Variation of some growth criteria and morphological traits for each genotype were recorded in the growing season of 2012 - 2013.High variability was observed in plant height, leaf area, number of inflorescence, number of flowers and fruit weight among genotypes To achieve PCR reactions, total genomic DNA was isolated from fresh leaves (2 weeks old). The average yields of DNA were in the range of 100 - 295 ng/?l with a purity ranging between 1.8 - 1.9.RAPDs amplifications were performed for genotypes fingerprinting by testing 27 Operon primers. DNA polymorphisms among genotypes were scored within detectable amplified fragments (their numbers and molecular weight) after agarose gel electrophoresis and staining with ethidium bromide. The 27 primers produced 442 of main bands, out of which 312 were polymorphic bands (70.5%) and 70 were monomorphic (15.8%) across all tested genotypes.Each selected primer produced between 60 bands (OPA - 14) to 290 bands (OPD - 13). DNA amplification products ranged in their size from 250 bp (OPA - 01, OPU - 14, OPX - 15, OPX - 19, OPT - 08 ( to 2755 bp (OPX - 18). The highest number of polymorphic bands (21 bands) was produced by primer OPU - 03, while the lowest number of polymorphic bands (3 band) was produced by both primers OPA - 14 and OPB - 17.The primers varied in their capacity in producing polymorphic amplified profiles among tomato genotypes which individually reflected genotype specific DNA profiles (fingerprints). The most important primers for this purpose were primers that produced more variety specific DNA profiles, such as OPD - 13, OPT - 08, OPW - 04, OPA - 04, OPA - 15, OPB - 18, OPU - 03, OPC - 09.The highest value of discrimination among genotypes in this study was obtained by primer OPU - 03, while the lowest discrimination value was produced by both primers OPA - 14 and OPB - 17. The primer efficiency ranged from 0.13 in (primer OPC - 09) to 0.02 in (primer OPB - 17). The lowest genetic distance was 0.2294 between genotypes Oula and Shady lady, while the highest genetic distance was 0.9459 between genotypes Fotton and Special pack. Cluster analysis (Phylogenetic tree) by un weighted pair - group method of arithmetic means (UPGMA) based dendrogram revealed that they were two main genetic groups (major clusters).The first small major clusters included four (four genotypes) while the second large major cluster included (15 genotypes). A total of 21 alleles were detected among the tested genotypes using five SSRs loci distributed on four chromosomes of tomato. The molecular size of bands obtained from amplification of SSR products ranged from 121 to 247 bp. Alleles ranged from one in (Tom 8 - 9, Tom 41 - 42 and Tom 67 - 68 loci) to twelve in Tom 49 - 50 locus. The values of heterozygosity for each locus ranged between 0.63 for Tom 31 - 32 and 0.89 for Tom 49 - 50 with a mean value of 0.30. The polymorphic information content (PIC) values for the SSR loci ranged from 0.45 in Tom 31 - 32 to 0.58 in Tom 49 - 50 loci with an average of 0.21. Each one of (Tom 8 - 9, Tom 41 - 42 and Tom 67 - 68 loci) produce 0.0 value for both heterozygosity and PIC. The study revealed that, The lowest genetic distance was 0.3244 between varieties Tamara and W arda, while, the highest genetic distance was 0.9177between varieties Helam and Super marimond. The genetic similarity values ranging from 0.0823 to 0.6756 depending upon the genetic distance values that ranging from 0.3244 to 0.9177, indicating the largest diversity with percentage of 32 to 91% among the tested genotypes. The analysis of the results obtained from genetic distances and Neighbor - joining dendrogram (unrooted tree) revealed that, the 19 tested tomato genotypes can be grouped into two major groups : first cluster included nine varieties distributed in two subgroups. The second major cluster included 10 genotypes which in turn divided into two subgroups.The relationship among genotypes was not concern to their morphological characters and geographical origins. The overall analysis of the results show that both SSRs and RAPDs markers are powerful tools in fingerprinting and revealing the genetic relationships among tomato genotypes.

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

All specimens were cultured and 10 Acinetobacter baumannii isolates were obtained from clinical specimens in a percentage of (0.76%) distributed in blood 1 (0.6%), urine 2 (1%), wound infection 1 (0.75%), burn 5 (0.85%) and throat 1 (2%). This study was conducted to determine the occurrence of carbapenem resistant A. baumannii isolates obtained from Hillah hospitals. Isolates were identified according to API20E system and further confirmed using PCR technique. Antibiotics susceptibility was assayed by using disks diffusion method according to CLSI recommendations. All isolates revealed positive results with rapid iodometric test indicting the ability of beta lactamase production. Phenotypic detection of carbapenemase production was performed using the imipenem - EDTA disk and modified Hodeg's test (MHT). Then isolates were subjected to monoplex PCR targeting blaOXA - 51, blaOXA - 23, blaOXA - 24, blaOXA - 58, blaIMP, blaSIM blaNDM - 1, blaNDM - 2 and blaVIM genes, as well as, efflux pumps genes. One of the identified isolates (10%) was found to be imipenem, meropenem and ertapenem resistant, this isolate gave positive result with the imipenem - EDTA disk and (60%) of isolates were positive to MHT. PCR experiments showed ; all isolates were harbored blaOXA - 51 gene, four (40%) isolates were harbored blaOXA - 23 gene, three (30%) isolates were harbored blaOXA - 24 gene, four (40%) isolates were harbored blaOXA - 58 gene, five (50%) isolates were harbored blaIMP gene, six (60%) isolates were harbored blaSIM gene, two (20%) isolates were harbored blaNDM - 1 gene, four (40%) isolates were harbored blaNDM - 2 gene, while none of these isolates harbored blaVIM gene. The present findings suggest that emergence of (OXA - 23, OXA - 24, OXA - 58, IMP, SIM, NDM - 1, NDM - 2) carbapenemase producing A. baumannii clinical isolates in Hillah City hospitals. Also there are indicative appearance of efflux pump genes ; (50%) for Ade - A and Ade - B each other, (40%) for Ade - C, (80%) for all of Ade - R and Ade - S, (100%) for all of Ade - I and Ade - J, and (50%) for Ade - Y. All isolates of A. baumannii appear as MDR, while only one appear to be as PDR. The trans - mobility of resistant genes was examined by trans - conjugation experiment ; the results indicated that only blaIMP and blaOXA - 23 genes were transferred horizontally in the current study. In attempting to investigate any blaNDM gene variation the results showed some different than NCBI - Blast A. baumannii blaNDM - 1 and blaNDM - 2 it may as a unique genotyping.These results revealed that carbapenemase producing A. baumannii were detected in both phenotypic and genotypic methods (PCR). This underlies the importance of their accurate identifications and reporting to prevent the emergence of complete resistance to the most potent drugs against A. baumannii in Babylon province.

المستخلص: The study consists of three parts related with patients of CRC as in : 1 - Molecular part 2 - Cytogenetic and molecular genetics part and 3 - Immunological part. In addition of their relatives of clinical and pathological diagnosis, genus, and tumor locations in 150 of Iraqi patients confirmed with CRC collected from Teaching Hospitals of some Iraqi governorates. The percent of male to female (54.66% / 45.43%) and the aged range of study were 16 to 80 years.The first part consist a study of five types of genes related with CRC represented by MLH1, MSH2, APC, K ras, and SMAD7 genes. Some of these genes develop with germline mutations as in MLH 1 exons1 and 15 so as MSH2 genes. While the rest genes related with a sporadic of CRC. All these genes were amplified by conventional polymerase chain reaction (PCR) for study the types of the mutations and their defect of these genes on CRC. The APC exon11and K ras exon1 genes were processed by single strand conformational polymorphism (SSCP) technique. The results of PCR - SSCP technique for two genes represented by appeared three types of bands, which were (AA), (AB) and (AC) bands. The important band was (AB) which constitutes the variability region represented by 84.2% and 44.82% in patients for both genes. The results of patients with mutated bands with high significant differences(P?0.05).compared with healthy control. Patients carried these bands subjected to PCR - Sequences technique. The analysis results for APC gene sequences were substitutions mutations type of single nucleotide polymorphism (SNP) change Cytocine to Thiamin (C>T) at 1972 location of genome. While the analysis results of Kras gene appeared two types of mutations, substitution and frame shifts represented by deletion mutation and so as appeared stop codon mutation.The other genes represented by MLH1, MSH2, and SMAD detected by direct PCR - Sequences. The results analysis of MLH1 gene, exon (1and 15) represented by nucleotides change with high frequencies of substitution mutation through exon1 at different locations of nucleotides. So as frame shift mutation type deletion through exon15. While for MSH2 gene, exon 6 from 6.66% represent by deletion mutation. A spread study for SMAD7 gene, exon4 were done through 30 patients average age 52 years (male to female 56.7% : 53.3%) confirmed colorectal adenocarcinoma compared with 15 healthy. A mutation of 20% of (SNPs) were identified.The second part which represented standard conventional cytogenetic and molecular genetics were done through peripheral blood culture (PBC). The study showed increasing of mitotic index (MI) in patients with significant differences (P?0.05) compared with healthy controls indicating for increasing of proliferation of the lymphocytes division. The study showed some chromosomal aberrations with significant, the majority of aberrations were higher significant in dwarf and aneuploidy chromosomes so as elongation chromosomes revealed significant differences (P?0.05) between patients and healthy. The appeared of Polyploidy chromosomes, with significant differences (P?0.05), that’s seem to be good indicator for cancer disease. The molecular genetics alterations which dependent on cytogenetic investigation were done through deletion of long arm of 5 chromosome which APC gene is located. The test elucidates the importance of inactivation (deletion) of APC gene in elicited of colorectal cancer. The study of 20 patients, were investigated by fluorescent in situ hybridization (FISH). The results showed 60% patients which have 5q arm deletion of (+). And (5%) have two deletions (++) which was a male aged less than 60 years. The results analysis explained significant differences (p?0.01) between studied group and deletion (+) of arm 5q. A correlation represented by significant differences (p?0.01)through dysfunction of APC gene deletion of 5q were found with high percent among sporadic adenocarcinoma 58.3%, with less in attenuated familial adenomatous polyposis (AFAP) and familial adenomatous polyposis (FAP) represented by the (25%), and (16.7) respectively.The last part related with immunological test were done by detection of tumor markers represented by Carcino Embryonic Antigen (CEA), IL - 33 and IL - 31.These markers represented a confirmative indicators for colorectal adenocarcinoma which were tested by ELISA technique in (79) patients confirmed with CRC of male and female. These tumor markers in tested with patients showed high significant differences (p?0.01) compared with healthy controls. Another immunological test for detection of Human papilloma virus (HPV) type 18 E6 gene expression in CRC by Immune histochemistry technique (IHC) in 71 (FFPET) of CRC. The results of this study showed there were a correlations between patients and adenocarcinoma positive HPV18 E6 infection 43.7% of patients infected with virus, with high significant differences (p?0.01) and higher infection in female (67.7%) than male (32.3%). So as a correlations were found between HPV18 E6 expression and tumor tissue locations, explained by high percentage 45.2% in rectum.While a tumor marker was (CD8+) was used to determine its role in human immune surveillance in tumor regions of CRC so as with regions which were infected by HPV. The study revealed high significant differences between healthy control and studied groups which have (CD8+) positive infiltration in tumor origins through detection by (IHC).In conclusions diagnosis of CRC can be detected by special genes like K ras gene through professional PCR processing, compact with tumor markers, so as Fluorescent in situ hybridization (FISH) technique provides a precise method which can be used for detection of alteration of molecular and cytogenetic related with CRC.

المستخلص: This study aimed to determine the frequency of Salmonella Typhimurium and its multi - drug resistance (MDR) status as a diarrheal causative pathogen in children younger than five years old, as well as to investigate the role of four probiotic microorganisms(L.acidophillus, L.casei, S.cerevisiae, S.boulardi) in controlling such infection.For this purpose, 128 stool samples of patients (76 males and 52 females) was included in this study. They were children suffering from diarrhea and fever who admitted to the “Central Pediatric Hospital” in Baghdad during the period from April to September, 2012. Their ages ranged from six days up to five years.The immunological effects of probiotics and MDR S. Typhimurium isolate in the experimentally infected and probiotic - treated mice were investigated via assessing the level of ten cytokines (IFN - ?, IL - 1?, IL - 4, IL - 10, IL - 12, IL - 17A, IL - 21, GM - CSF, RANTES and IP - 10) in the lavage of small intestine. Accordingly, five groups of mice were used in the in vivo part of this study; Mice in group I received probiotic for 7 successive days, challenged with S. Typhimurium on day 8, and dissected on days 14 and 21. Group II wassimilarly treated, but the probiotic was continued for 14 days. Group III was given the probiotic only, and group IV was challenged with S. Typhimurium, while group V was the control.Results obtained in this study could be summarized as follows : 1. Out of 128 stool samples, S. Typhimurium was isolated and identified in 9 samples only (7.03%). All isolates were totally resistant to nalidixic acid, with the exception of one isolate which showed intermediate sensitivity.Furthermore, only one of these isolates (symbolized B) was found to be resistant to three antibiotics (ampicillin, amoxicillin and nalidixic acid).Therefore, this isolate was considered as an MDR isolate and selected for further experiments in the study.2. When the susceptibility of MDR S. Typhimurium isolate B was further assessed in vitro by using four probiotics (Saccharomyces cerevisiae, S. boulardi, Lactobacillus acidophilus and L. casei), results showed that S.cerevisiae and L. acidophilus were the most efficient by recording the highest inhibition zones (12.6 and 16.3 mm, respectively), therefore, they were further investigated for their anti - S. Typhimurium effects in vitro and in vivo. 3. By using the unconcentrated and (one - fold, two - fold, three - fold) concentrated filtrates of these two probiotics, it was found that the three - fold filtrates were most efficient in their antibacterial activity by recording the highest inhibition zones (25.0 mm for S. cerevisiae and 31.0 mm for L. acidophilus.4. Significant increases in the values of liver index were observed in mice of group I treated with L. acidophilus at 21 days (10.73%) compared to the corresponding group treated with S. cerevisiae (7.41%) or other four groups. For spleen, index value in L. acidophilus groups was higher than the corresponding groups in S. cerevisiae. Mice treated with a probiotic alone or in a combination with the pathogen showed significant increases in the spleen index values of all groups compared to the untreated mice (group V).5. Both probiotics were effective in reducing S. Typhimurium colony forming units per plate (cfu/plate) in the liver and spleen. In liver, mice in group IV showed a count of 224.4 cfu/plate, which was significantly higher than any count in groups of L. acidophilus and S. cerevisiae. Group II mice recorded better results than group I mice, while the lowest counts (21.6 and 27.8 cfu/plate for L. acidophilus and S. cerevisiae, respectively), were observed at day 21.6. The ten investigated cytokines showed different levels in the small intestine wash; such differences were subjected to the group of mice underinvestigation and type of probiotics used. In addition, variations in IFN - ?/IL - 4, IFN - ?/IL - 10, IL - 4/IL - 10 and IL - 17A/IL - 10 were also observed.

For these purpose, A total of 150 clinical specimens (skin scrapings (80), hair fragments (60) and nail clippings (10)) were collected from 100 patients (70 males&80 females) whom clinically diagnosed with dermatophytosis after attendingto the dermatology and venereal diseases centre of Mergan Teaching hospital and private clinic in Babylon city from Feb. 2014 to May 2014. T. rubrum were isolated and identified using cultural, biochemical and physiological tests. Isolates were then subjected for confirmation by PCR, genotyping using RFLP - PCR, sequencing and registration of these sequences in GeneBank for obtaining accession numbers then phylogeny. The growth conditions, were tested, in addition to, the genetic expression of proteases (exocellular protease and endocellular aminopeptidase) were determined using Real - Time PCR. Out of 150 specimens, 24 (16%) isolates were dermatophytic fungi and only 5 (20.8%) of them belong to T. rubrum. The influence of cultural conditions in growth of T. rubrum showed that the 30 ?C, pH 6, SDA medium and 7 days incubation were the optimal conditions for its growth. Proteolytic activity of isolates of T. rubrum against casein as a substrate revealed an ability to produce protease in solid and liquid media after 14 days of incubation. This activity was varies according to the type of isolate where the isolate No.1 (isolated from skin) gave a high proteolytic activity (5.6cm) in solid media and (80.1U/ml) in liquid media in comparison with other tested isolates (No.2 - No.8). on the other hands, the 9 days of incubation, 30 ?C, pH 7 and 0.5% substrate concentration were the optimal condition for proteolytic activity of these isolates. The molecular tests confirmed that all tested isolates belong to T. rubrum with amplicon size (601bp) after amplification of ITS1 primers using PCR technique. While the RFLP - PCR technique showed the presence of two genotypes (I%II) belong to T. rubrum with subgenotypes (Ia - Id) and (IIa - IId) respectively. The relative quantification of proteolytic activity (exocellular protease and endocellular aminopeptidase) produced by T. rubrum genotypes were expressed by using Real - Time PCR after amplification of the target gene of ptotease and aminopeptidase in comparison with housekeeping gene (? - actin) as a reference gene. The results showed the up - regulation of gene encoded to exocellular protease than the down - regulation of endocellular aminopeptidase produced by T. rubrum in the presence of casein as a substrate. The internal transcribed spacer 1, partial sequence, 5.8S ribosomal RNA gene and internal transcribed spacer 2, complete sequence and 28S ribosomal RNA gene, partial sequence of local isolates of T. rubrum were used for sequencing, registration in Genebank - NCBI and phylogeny. Five accession numbers were recorded and available to NCBI, EMBL in Europe and the DNA Bank of Japan. These accession numbers were : KP979787, KP979788, KP979789, KP979790, KP979791. Phylogenetic relation between local strains and world strain showed a high identicasl with T. rubrum (GQ376105.1). This is the first study in Iraq which employed sequencing, registration of sequences in Genebank - NCBI and carrying out phylogeny of local and world strains of T. rubrum.

Out of the 120 women serum samples analyzed by enzyme ELISA, the results of percentage of anti - Coxiella burnetii IgM and IgG in human samples were 36 (30 %). The percentage of anti - C. coxiella IgM in human samples were 10 (8.333%), while the percentage of anti - C. Coxiella burnetii IgG in human 26(%21.667%).. In animals total of (80) serum samples, the percentage of anti - C. coxiella IgM and IgG in animals' serum samples were 31(38.75%) The percentage of anti - Coxiella burnetii IgM in animals 10 (12.5%), while, the percentage of anti - C. coxiella IgG in animals are 21(26.25 %). PCR technique used for identification of Coxiella burnetii in human and animals samples by targeting three genes including outer membrane protein (com1 and com2), 16S rRNA and transposase insertion element (IS1111) genes. In human blood samples the com1 and com2 genes detected in 23of 120 (19.166%) samples and in breast milk samples 1 of 7 (14.28%). and not detected in placental samples. The 16S rRNA gene was detected in 16 of 120 blood samples (13.33%) and in breast milk samples and placental samples were not detected. The IS1111 gene was detected in 9 of 120 blood samples (7.5%) in human blood samples, also were not detected in milk and placental samples.. In animals blood samples the com1 and com2 genes were detected in 19 of 80 blood samples (23.75%) and were not detected in milk and placental samples. The 16S rRNA gene detected in the same percentage of com1 and com2 genes 19 of 80(23.75%) and in the milk samples and placental samples not detected. The IS1111 gene detected in 10 of 80 (12.5%) in animal blood samples, also were not detected in placental samples. An isolation of Coxiella burnetii which identified by ELISA and PCR via inoculated Coxiella burnetii buffy coat samples in embryonated chicken eggs from 6 to7 days old and then completed an incubated to 10 - 15 days, harvested yolk sac contains then detecting Coxiella burnetii by PCR. The results of PCR after inoculation of (43) samples were positive in PCR (100%). Statistical analysis revealed no significant different between ELISA test, PCR and isolation results in human and animals samples. These mean that we can use the ELISA in the primary diagnosis. The correlation coefficient was highly significantly between human and animal samples at 0.01%.

Some studies focused on the role of insulin status, while others concentrated on lipid disturbances or even oxidative stress disorders in the diabetes. This study was conducted on randomly selected 68 type 2 diabetic patients (27 Males and 41 Females) attending the diabetes mellitus center in Al - Sadder Teaching Hospital in Al - Najaf province, Iraq and a group of 20 apparently healthy subjects (10 Males and 10 Females) were included as a control group. The study was carried out from February 2013 to July 2013. The age of patients and control groups were range of 35 - 65years. The concentration of fasting blood glucose, cholesterol, triglyceride, LDL, VLDL, HDL, Apelin, Omentin, Vaspin, Visfatin and BMI were estimated in patients and control groups. The results show significant increase (P?0.05) in fasting blood glucose, cholesterol, triglyceride, LDL, VLDL, Apelin, Vaspin and Visfatin levels in patients compared with control groups, also the results show significant decrease (P?0.05) in HDL and Omentin level in patients compared with control groups. The results revealed that all biomarkers (Apelin, Omentin, Vaspin and Visfatin) not significant difference (P>0.05) in patients at different ages. The results also revealed that biomarkers (Apelin, Vaspin and Visfatin) levels increase significantly (P?0.05) in males than females in both patients and control groups, while the result of omentin level reveal no significant difference (P>0.05) between males and females in both patients and control groups. The results also revealed that significant increase (P?0.05) in BMI in patients compared with control groups. The results also show that biomarkers (Apelin, Vaspin and Visfatin) concentration increase significantly (P?0.05) with increasing BMI in males than females compared with control groups, while the result of omentin concentration show no significant difference (P>0.05) in patients and control groups and show lower significantly increase (P?0.05) in females than males compared with control groups. The results have been shown significant positive correlation (P?0.05) between biomarkers (Apelin, Vaspin and Visfatin) and FBG, cholesterol, triglyceride, LDL and VLDL in patients (males and females), while the results have been shown significant negative correlation (P?0.05) between biomarkers (Apelin, Vaspin and Visfatin) and HDL in patients (males and females). The results also have been shown significant negative correlation (P?0.05) between omentin and FBG, cholesterol, triglycerides, LDL and VLDL in patients (males and females), while the results have been shown significant positive correlation (P?0.05) between omentin and HDL in patients (males and females). The results also have been shown no significant correlation (P>0.05) between Vaspin and FBG in patients (males and females). The present study concluded that Apelin, Omentin, Vaspin and Visfatin levels maybe that could be adopted as markers for detection and diagnosis of diabetic patients type 2.

المستخلص: ان من الحقائق العلمية الثابتة اليوم ان الفحص الروتيني للسائل المنوي يعد عاملا تنبؤيا اجماليا للقدرة الاخصابية للرجال، ولذلك فان حاجة متزايدة بدات تبرز لاكتشاف فحوصات وظيفية جديدة في عملية تقييم العقم عند الرجال. ان الهدف الاساس من هذه الدراسة هو تعزيز الج | It is a scientific fact today that routine seminal fluid analysis is a key predictor of male reproductive potentiality ; so that there is an increasing need for finding out other functional tests in the assessment of male infertility. The main goal of the current study is to consolidate the scientific and practical efforts concerned with male infertility assessment especially from immunological and genetic aspects. The study was carried out between January 2013 and December 2013 including one hundred (100) selected infertile men who attended the Fertility Center in al - Sadr Medical City in Al - Najaf Al - Ashraf Governorate, the study also included twenty (20) healthy volunteer fertile men as a control. Serum and seminal antisperm antibodies (ASA) were determined by ELISA (Enzyme Linked ImmunoSorbent Assay) technique ; sperm chromatin condensation was evaluated by aniline blue staining (AB) ; sperm DNA fragmentation (damage) was evaluated by toluidine blue staining (TB). The results showed that the incidence and concentration of serum and seminal plasma ASA in the infertile men were significantly (p<0.05) higher than that in control fertile men. The incidence and concentration of serum and seminal ASA were also significantly (p<0.05) higher in normozoospermic infertile patients than that in control fertile men. There was a high significant negative correlation (p<0.01) between the concentration of serum and seminal plasma ASA in the infertile men and sperm motility and progressive motility, the concentration of serum and seminal ASA also showed a high significant positive correlation (p<0.01) with sperm agglutination, and a significant positive correlation (p<0.05) with seminal WBC count. The results also revealed that there were no significant effects (p>0.05) for patients' age, infertility duration, ABO blood groups and smoking habits on the levels of ASA in the serum and seminal fluid, while higher significant increase (p<0.01) in serum and seminal ASA concentrations was observed in infertile patients with varicocele as compared with those without. The results have also revealed that the percentage of sperm with chromatin decondensation and DNA damage has shown a high significant (p<0.01) increase in infertile patients compared to fertile men. There was also a significant increase (p<0.05) in sperm DNA damage in normozoospermic infertile patients comparing with fertile men, but no significant difference (p>0.05) was found in sperm chromatin condensation between normozoospermic patients and fertile men. Both sperm chromatin decondensation and sperm DNA damage showed a significant positive correlation (p<0.05) with sperm morphology, and a significant negative correlation (p<0.05) with sperm concentration, motility and progressive motility. The present study also revealed that the level of chromatin decondensation has been affected by patients' age, infertility duration, smoking habits and varicocele. It was observed that the higher percentage of chromatin decondensation was recorded in patients older than 37 years, and in patients subgroups with infertility duration more than 15 years, it was also higher in smoker as compared with non - smoker patients and in those with varicocele as compared with those without. Similarly, the level of sperm DNA damage has also been affected by patients' age, smoking habits and varicocele. It was observed that the highest percentage of sperm DNA damage was recorded in patients older than 37 years. The highest level of sperm DNA damage was also seen in smoker patients as compared with non - smokers and in those with varicocele as compared with those without. In contrast, the effect of infertility duration on sperm DNA damage was not statistically different (p>0.05). The correlation and regression results recorded high significant correlations (p<0.01) between serum ASA and seminal plasma ASA, and between sperm chromatin decondensation and sperm DNA damage. However, there was no significant correlation (p>0.05) between the level of serum and seminal ASA and each of sperm chromatin decondensation and sperm DNA damage. The current study concluded that the defects in sperm chromatin status (chromatin decondensation and DNA damage), and the immunological disorders caused by serum and seminal plasma ASA may - at least partially - contribute to the etiology of infertility of the patients under study, even in those with normal seminal parameters. However, it seems that ASA affect fertility in a pathway that is different from that affected by sperm chromatin defect. It was recommended that both sperm chromatin staining techniques and ASA tests could be routinely used as complementary tests to diagnose infertility.
