Abstract: The purpose of this thesis is to report quantum chemical investigations into a series of problems related to contemporary organometallic chemistry. In recent years density functional approaches have become the most commonly used theoretical methodology in organometallic chemistry. Alongside these developments, a number of new tools for analyzing electronic structure such as topological analysis of electron density (Atoms in Molecules theory) have emerged. As a result, theory is now in a position to compute ab initio many of the experimental observables that underpin modern organometallic chemistry.The bonding in the Triosmium carbonyl cluster 1 [Os3(? - H)(? - ?2 - dpa - N,N)(CO)10] and Triosmium carbonyl cluster 2 [Os3( ? - H)2(NHC)(CO)9] are explored using the Quantum Theory of Atoms - in - Molecules (QTAIM). The metal - metal and metal - ligand bond critical points properties ?(r), ?2?(r), H(r), G(r), V(r) and ellipticity, and also the bond delocalization indices ?(A, B), are correlated with the data from previous studies of the organometallic systems. These results have allowed a comparison between topological properties of different atom - atom interactions. In the core of dihydride triosmium cluster 2, Os3H2 part, the topological data recognizes the existence of a bond path in the dihydride bridged Os atoms, Os(1) - Os(3) edges, whereas in monohydride triosmium cluster 1 there is no direct bond path has been found for the interaction between the hydride bridged Os atoms, although a non - negligible delocalization index ?(Os(1)...Os(2)) has been obtained for this non - bonding interaction. A multicenter 4c - 4e interaction is proposed to exist in the core part, Os3H, in cluster 1 and bridged part, Os(1) - H(1) - Os(3) - (H2) in cluster 2. In addition, an interaction of 5c - 5e type is proposed to exist in the core part, Os3H2. All topological parameters calculated for the Os - N and Os - C bonds between the osmium atoms and the pyridyl and NHC ligands in compound 1 and 2, respectively, are similar, and they confirm that these interactions are pure ? bond. The analysis of the topological parameters of the NHC and pyridyl ligands bonds confirm the existence of ? - electron delocalization within the six - membered ring of pyridyl ligand and hindered ? - electron delocalization within the five - membered ring of NHC ligand with some double - bond character in the interaction of the carbine C atom with the adjacent N atoms.

Abstract: في الواقع، لم تلقي عملية فصل واستخلاص الكميات الضئيلة من الادوية في العينات الحيوية وكذلك في المستحضرات الصيدلانية اهتماما واسعا وكبيرا باستعمال مايسمى الاستخلاص بنقطة الغيمة. وفي هذا الصدد، نعتقد ان العمل البحثي الحالي سوف يسهم في فتح افاق جديدة في تصم | The separation and extraction of trace amounts of medicaments in biological specimens, as well as in pharmaceutical formulations have not received much attention by using the so - called cloud - point extraction (CPE). In this context, we think that the present research work will contribute to opening new prospects in designing procedural steps and expands the applications of the cloud point extraction methodology in most important areas, including pharmaceutical sciences, forensic and environmental analyses. The present work concentrates on the developing of new eco - friendly procedures for determination of two selected antibiotic medicaments namely cirprofloxacin chloride (CIPRO) and norfloxacin (NOR) using iron (III) ion in human serums and pharmaceutical formulations, as well as the exploitation of these two drugs in chemical analysis as chelating agents for the detection of iron in pharmaceutical formulations via using cloud point extraction coupled with molecular spectrophometry. Generally, these methods implicate the use of a nonionic surfactant (Triton X - 114) as an extracting medium which entrap the hydrophobic colored complex formed between one of these drugs and iron (III) ion in acidic medium as a reaction system for designing the CPE procedures.This thesis includes three main chapters as follows;Chapter One summarizes some theoretical and practical principles of cloud point extraction (CPE) methods and then highlights the knowledge of the target analytes (CIPRO, NOR and iron) in term of their structures, pharmacological importance besides a concise chemical literature review for the estimation of these analytes by different analytical techniques. Chapter Two consists of an outline of instrumental techniques , general apparatus and chemicals used in the present work. The full analytical procedures for CPE which have been designed for the determination of the target analytes under study are made in this thesis.Chapter Three covers a detailed study for the discussion of the analytical data obtained throughout this work which can be summed up as follows;A. Formation of chelates between CIPRO or NOR and Fe(III) in acidic medium , where the drugs have individually been estimated in the resulting complex by spectrophotometry after the cloud point extraction at each respective ?max, and the use of developed method so that to determine any of the interested drug in human serum and pharmaceuticals. At first, the study was conducted to pinpoint the optimum conditions for the formation of complexes by CPE and the results were as follows; 1. The optimum experimental conditions for Fe - CIPRO and Fe - NOR complex for the determination of CIPRO and NOR respectively : H2SO4 concentration (5x10 - 4 M and 2.5x10 - 4M; Fe(III) concentration ( 6 ?g mL - 1 and 10 ?g mL - 1); Triton X - 114 amount ( 1%) for both drugs; temperature and time ( 75 °C at 25 min and 65 °C at 20 min).2. The achieved analytical figures of merit on applying the developed methods for CIPRO and NOR are : linear range (2.5 - 120 ?g mL - 1 ) for drugs, limit of detection (0.770 and 0.204 ?g mL - 1), Enrichment factor (143 and 280 fold), extraction efficiency (96.46 and 96.62%) and mean recovery percentage (98.89±0.87% and 98.95±1.09). 3. The newly established procedures have been applied for the determination of CIPRO and NOR in human blood serum and pharmaceuticals. For the determination of these medicaments in serum samples , the statistical paired t - test was used to test the significance of the proposed method comparing with the conventional UV - spectrophotometry, while in pharmaceuticals, the findings were compared statistically with quoted values that stated by the manufactures. B. Iron (III) ion was also determined in the pharmaceutical formulations based on the above reaction system in (A) via formation of yellow colored complexes with each medicament which extracted by micelles generated by CPE and subsequently detected spectrophotometrically at the same ?max of the above mentioned complexes. The optimum established conditions and the analytical data obtained could be summarized as follows : 1. The same optimum conditions were used in (A) except that the concentration of CIPRO or NOR here was of 7x10 - 5 M and Triton X - 114 amount of 0.6% in final solutions.2. The analytical figures of merit obtained on applying the developed methods for iron using CIPRO and NOR respectively; linear range (5 - 150 ng mL - 1); limit of detection (2.67 and 3.42 ng mL - 1); preconcentration factor (71 and 83 fold); mean recovery percentage (99.78±0.53% and 98.77±2.29); extraction efficiency (99 and 98.7%). 3. The effect of some additives of the pharmaceutical formulations was also studied and the iron determined in three selected formulations collected from local drugstores. The results were compared statistically with quoted values and shown not to be significant at 95% confidence level.

Abstract: 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.

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

Abstract: 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.

Abstract: استخدمت في هذه الدراسة 125 عينة من حديثي الولادة لتقييم التعبير الجيني لل UGT1A1 والكشف عن المتغاير UGT1A1*28. استخدمت 85 عينة منها في تقييم التعبير الجيني لل UGT1A1, بينما استخدمت ال 40 عينة المتبقية للكشف عن المتغاير UGT1A1*28. اجريت الدراسة الحالية في | A cohort of 125 neonates enrolled in the present study 85 of which subjected to the UGT1A1 expression analysis and forty (40) independent subjects examined for UGT1A1*28 variant. 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.

Abstract: العكبر (صمغ النحل) Propolis هو نتاج نحل العسل الذي اكتسب شعبية في الطب البديل وذلك بسبب خصائصه الحيوية، وقد استخدم بشكل واسع في الاطعمة الصحية. ان الدراسات المتعلقة بتاثير العكبر العراقي قليلة. ولهذا السبب, فان الهدف من هذا البحث هو تحليل تاثير العكبر الع | Propolis is a honeybee product that has gained popularity in alternative medicine, due to its biological properties and it has been intensively used in health foods. Studies concerning the effect of Iraqi propolis are rare. Therefore, the goal of this work is to analyse the effect of Iraqi propolis on some hematological and biochemical parameters in alloxan - induced diabetic rabbits, as well as study the histological observations of the pancreas, liver and kidney. Female local rabbits (Oryctolagus cuniculus) were used for this study. The overall number of animals used was 30.They were randomly divided into five groups. Diabetes was induced in all rabbits, except normal control, by a single dose of alloxan (150 mg/kg, i.v.). Development of induced diabetes mellitus was confirmed on first week after alloxan administration by examining the fasting glucose level in the blood taken from marginal ear vein. Rabbits with glycaemia were treated with alcoholic extract of propolis for 23 days. Diabetic control group did not treat with propolis. The treated animals were subdivided into three groups according to the dose of propolis extract. Three oral concentrations of propolis extract were investigated (50, 100 and 200 mg/kg/day).The following parameters have been studied were changes in weights of body, liver and kidneys ; changes in the hematological values that include erythrocytes, hemoglobin, leukocytes and hematocrit also changes in the biochemical values which included glucose, total protein, triglycerides, total cholesterol, aspartate transaminase (AST), alanine transaminase (ALT), blood urea, creatinine and Malondialdehyde (MDA), in addition histopathological study of pancreas, liver, and kidneys. The results indicate a significant decrease (P < 0.05) in the body weight of alloxan - induced diabetic rabbits in comparison with control group, while there were significant increases in the weights of liver and kidneys. The present study showed that alloxan induced significant decreases (P<0.05) in all primary blood indices; erythrocytes, hemoglobin, packed cell volume (hematocrit) and leukocytes. Also, serum biochemical changes showed significant increases (P<0.05) in glucose, total protein, triglycerides, total cholesterol, AST, ALT, blood urea, creatinine, and MDA comparison with control group.Histopathological changes in pancreas, liver and kidneys, observed microscopically, revealed degrees of damage in the tissues, while these organs of control groups exhibited a normal architecture. The treatment with alloxan resulted in several forms of histological alterations such as cytoplasmic vacuolation, degeneration, necrosis, cell hypertrophy, nuclear diploid, diffusion of inflammatory cells, dilatation in ducts, stagnation in secretory fluid. in addition, hemorrhage, dilatation and congestion in blood vessels and disorganization of histologic architecture, Generally, the gradual improvement in blood values was noticed with the increase in concentration alcoholic extract of propolis and return back the normal histological shape of pancreas, liver and kidneys. Propolis extract in rabbits had a potent antihyperglycemic effect, antioxidant activities, radical - scavenging capacities, tissue regeneration properties, and that may be due to the high biological activity and nutritive values contents in bee propolis. In conclusion, the results suggest that propolis could potentially contribute for the prevention and treatment of diabetes mellitus.

Abstract: 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.

Abstract: This study has been conducted for the first time in Najaf / Iraq, and the study included the preparation of a local inactivated vaccine (whole and subunit).The number of cases infected with seasonal influenza virus were 647 cases out of one thousand suspected case. They were distributed into eleven groups. Seasonal influenza virus was detected by two diagnostic methods (rapid test device and real time PCR).The present study has reflected that the most diagnosed cases infected with seasonal influenza virus during the period extended from March 26, 2012 up to April 30, 2013 represented by were type A (H3N2) (283) cases. Whereas H1N1 (148) cases, H3N2+H1N1, (56) cases, H1N1 + H3N2 + B were (30) cases and 130 cases were infected with type B.Current study also revealed that age group of 46 - 60 years old infected with seasonal influenza virus were (159) case including (368) male and females were (279) of different infected group..The spread of seasonal influenza virus in Najaf varies from one region to another depending on the population density. Clinical cases were collected randomly during the months of the year. It has been found that the spread of disease has something to do with temperature and humidity as high humidity and low temperature lead to increased spread of the disease because of their relationship at the stage of the spread of epidemic influenza that spread from Dec 26, 2012 and up to April 1, 2013 in addition to expatriates infected..Two techniques were used for isolation of seasonal influenza virus first inoculation of embryonated chicken egg and secondly chicken fibroblast cell culture.It was found that at the embryonated egg lethal dosage (ELD 50 / 0.5 ml) (109.6) whereas tissue culture infective dosage (TCID50 / 0.1 ml) was (109.3) of (H1N1+ H3N2) and type (B) virus..Virus was purified by two ways that are depending on the vaccine type. The gamma irradiation that dosage used for inactivating vaccine of the purified virus which was extracted from allantoic fluid and tissue culture was (5.702) mSv/h for subunit virus vaccine type whereas gamma irradiation dosage for complete (whole) virus vaccine was (8.816) mSv/h. The results proved that immunoglobulins (IgM, IgA and IgG) levels as well as (IL - 17, IL - 10 and INF - 1?) indicated significant differences among vaccinated, infected and control groups.Subunit and whole virus vaccine extracted from chicken fibroblast cell culture are considered the best of derived from virus propagated in embryonated chicken eggs.Subunit virus vaccine is better than the whole virus vaccine derived from virus propagated in embryonated chicken eggs and extracted from chicken fibroblast cell culture.The current study also reflected that locally prepared virus subunit vaccine and purified whole virus killed vaccine capable of inducing humoral and cellular immune response in experimentally vaccinated rats..Histopathological changes appeared clearly on tissue sections (lung, trachea, heart, liver, spleen, kidney) of the infected group as compared with control and the vaccinated groups.

While for detection CMV were initially identified by serological technique (ELISA, MiniVIDAS) to detect anti - CMV IgM and anti - CMV IgG; then confirmed employment molecular technique using Real Time Polymerase Chain Reaction for the detection the presence of DNA of CMV. Samples were collected from patients and control to estimation immunological level (C3, C4, IL - 10 & TFN - ?) by using ELISA and radial immunodiffusion method.The results showed that 76 HBsAg seropositive in all age groups but the age group 44 - 54 year revealed high significance (p<0.05) than other age groups. While 35 out of 76 seropositive with HBc Ab, the age group 55 - 65 years showed high significance (p<0.05) than other age groups, and males more infection than females. The result also revealed that the AIH disease was 5 out of 76 patients infected with Type 1 AIH. Included 2(40%) have demonstrated the infection HBsAg positive with reactivation CMV While 3(60%) infected with HBsAg only.The results showed that 68 out of the 76 samples were positive for anti - CMV IgG antibodies, and 4(5.26%) samples were positive for anti - CMV IgM. While the MiniVIDAS test results showed 73 out of the 76 samples was positive for anti - CMV IgG antibodies. 2(2.6%) were positive for anti - CMV IgM antibodies. The results of the Real - Time PCR revealed that DNA of CMV were detected in 23 out of 76 patients were found in all age groups with viral loads ranging from (0.24 - 1730000) Copies/ml, and the results of controls group in Real - Time PCR were CMV negative. The results of cytokines (TNF - ?) showed a high significance (P<0.05) elevation in the serum of all patients than control (419.3 ± 27.8) pg/ml, and the results that AIH showed increase in cytokine level was (1218.2±44) pg/ml than other patients. Whereas chronic hepatitis B patients recorded high significance (P<0.05) in level (IL - 10) was (901.5±22.2) pg/ml than other patients and control (373 ±30.3) pg/ml. According to sex no - significance difference between males and females in results of cytokines profile (IL - 10, TNF?). Complement fraction C3 decreased in all patients compared to those healthy control, while the AIH patient recorded high significance (P<0.05) 142.2±8 mg/dI than the other patients. In regard to C4 was revealed normal level in all patients compared with control groups while in the AIH revealed high significance (P<0.05) was 41.7±5.1 mg/dI compared with other patients and no - significance difference (P<0.0) between males and females in level of C3and C4.The overall finding results showed that the activation cytomegalovirus with hepatitis B virus Contribute to the induction of AIH and cause immune suppressor for them by increase and decrease many immune factors.

Abstract: The present study is intended to asses serum levels of Thrombospondin - 1, Fasting blood glucose, Glycated Hemoglobin A1c, Lipid profile and BMI in type 2 diabetic patients, also correlation between Thrombospondin - 1 with all criteria above in both males and females.The study was conducted on randomly selected 65 type 2 diabetic patients (34 males and 31 females) attending the diabetes mellitus center in Al - Sadder Teaching City in Al - Najaf province, Iraq and a group of 24 apparently healthy subjects (12 Males and 12 Females) were included as a control group. The Study was carried out from August 2013 to February 2014.The patients' age was ranging of 35 to 64 years old.The results indicated a significant increase (p<0.05) in serum FBG, Cholesterol, TG, VLDL - C, LDL - C, TSP - 1 levels and a significant decrease (p>0.05) in serum HDL - C level in diabetic patients in comparing with healthy groups. The results also revealed that significant increase (p<0.05) in serum HbA1c level and BMI in diabetic patients in comparing with healthy groups.The results also revealed no significant differences (p> 0.05) in serum Cholesterol, Triglyceride, VLDL - C, LDL - C, HDL - C and TSP - 1 levels between males and females in both patients and health groups, while the results of FBG and HbA1c levels increase significantly (p<0.05) in females than males in both patients and health groups.The results show that Cholesterol, Triglyceride, VLDL - C, LDL - C, TSP - 1, FBG and HbA1c levels increase significantly (p<0.05) in both males and females patients groups in comparing with males and females of healthy groups respectively, and a significant decrease (p<0.05) in serum HDL - C in both males and females patients groups in comparing with males and females of healthy groups respectively.The results indicated a significant increase (p<0.05) in serum TSP - 1 level in females than males patients at same BMI (over weight and obese) except normal weight there is no significant differences (p>0.05) and there is no significant differences (p>0.05) between males and female of control groups at same BMI.The results show that TSP - 1 increase significantly (p<0.05) with increasing age of patients in males and females patients and the ages (55 - 64y) are highly significant(p<0.05) than (45 - 54y) and (35 - 44y), But there is no significant differences (p>0.05) in males and females of healthy groups at different ages. while there is a significant increase (p<0.05) in serum TSP - 1 level at same ages in both males and females patients in comparing with males and females of healthy groups respectively. The results also indicated that TSP - 1 increasing significantly (p<0.05) with increasing duration of disease in males and females patients and the (11 - 15y) reveals a highly significantly (P<0.05) than (6 - 10y) and (1 - 5y). The results have been shown significant positive correlation (P<0.05) between TSP - 1 and FBG, TSP - 1 and HbA1c, TSP - 1 and BMI, TSP - 1 and cholesterol, TSP - 1 and TG, TSP - 1 and LDL - C, TSP - 1 and VLDL - C in (males and females), males, females DM patients. The results have been shown significant negative correlation (P<0.05) between TSP - 1 and HDL - C in (males and females), males, females DM patients. The present study concluded that Thrombospondin - 1 and HbA1c levels were markers for detection and diagnosis of diabetic patients type

Abstract: The study aimed to isolate and identify the Enterococcus spp. from different clinical specimens and study the virulence factors of predominant species, as well as detected the virulence factors encoding genes such as efaA (endocarditis - associated antigen), esp (enterococcal surface protein), eep (stimulating of pheromones expression) and enlA (enterolysin A) genes by PCR techniques.There were three hundred clinical specimens collected from patients suffering from different clinical infections during the period from September 2013 to January 2014 in AL - Sadder Medical City and AL - Hakem General Hospital. The identification of the Enterococcus spp. isolates were depended on colonial morphology, microscopic examination and biochemical tests as a primary identification. The final identification was performed with the automated VITEK - 2 compact system using Gram positive - Identification (GP - ID) cards.According to the results obtained by the VITEK tests forty two clinical isolates of Enterococcus were detected, which distributed into : (22) isolates from urine, (8) vaginal swabs, (6) seminal fluid, (4) throat swabs and two isolates from wound swabs with no isolates from cerebral spinal fluid, stool and blood specimens.This study revealed that the E. faecalis is more distributed with 25(59.52%), followed by E. faecium with 10 (23.80%), E.avium with 5 (11.90 %), E. durans and E. raffinosus with 1(2.39%) for each.The study investigated the virulence factors of E. faecalis, E.faecium and E.avium, which play a major role in enterococcus pathogenicity. E. faecalis and E.faecium had the ability to producecapsule, gelatinase, biofilm, adhesion, protease, bacteriocin, haemolysin and cytolysin except ? - lactamase produced only by E. faecalis while E.avium produced all these virulence factors except gelatinase, bacteriocin and cytolysin.The results revealed variation in the resistance of bacteria to antibiotics, E.faecalis express absolute resistance (100%) to Erythromycin, high resistance against Gentamycin, Tetracyclin and Vancomycin but high susceptibility to Ciproflaxacin and Penicillin and moderate susceptibility to Chloramphenicol. E.faecium exhibited absolute resistance (100%) to Erythromycin, Gentamycin and Tetracyclin, high resistance against Chloramphenicol, Penicillin and Vancomycin but high susceptibility to Ciproflaxacin while E.avium exhibited susceptibility (100%) to all these antibiotics except Tetracyclin showed absolute resistance.Then detected the virulence factors encoding genes : efaA, esp, eep and enlA genes by using PCR techniques and Electrophoresis Systems.Finally, The genotypic method. Regard to genotypic study the outcome showed that 21(84%) isolates of E.faecalis, 4(40%) of E.faecium and 5(100%) of E.avium were carrying efaA gene and 17(68%) of E.faecalis, 5(50%) of E.faecium, 5(100%) of E.avium were carrying esp gene while eep gene was carrying only by E.faecalis and E.faecium ; 12(48%) and 3(30%) respectively. Also the results revealed that only 1(4%) isolates of E.faecalis have enlA gene.
