Its identification was done by UV - Vis spectrophotometer, IR and C. H. N. Depending on the results, we found the correspondence between the theoretical calculation and the experimental ones with a way to suggest the final structures of the prepared reagents. The purity of these reagents was tested through thin layer chromatography.The prepared reagents are : 1. 2[(4 - Methyl phenyl )azo] - 4 - Methyl phenol (MePAMP)2. 2[(4 - Chloro phenyl )azo] - 4 - Methyl phenol (CPAMP)3. 2[(4 - Methoxy phenyl )azo] - 4 - Methyl phenol (OMePAMP)4. 2[(4 - Nitro phenyl )azo] - 4 - Methyl phenol (NPAMP)The second part deals with the study of chromatographic behavior of organic prepared reagents dissolved in ethanol according to gas chromatography on stationary liquid phases as capillary columns with different polarities as zebron (FFAT) which is characterized with high polarity, silica fused (BP10) with a medium polarity and poly phenyl siloxine (OV - 5) that appears with low polarity.Gas chromatography was equipped with a flame ionization detector (FID) and the nitrogen as carrier gas with flow rate 30cm3min - 1 at different column temperatures ranged 100C increments depending on columns maximum operation temperature, column inlet temperature and detector temperature were higher than the separation column (25,50) 0C respectively.This investigation attempts to find the optimum conditions for the sequential separation were defined for the azo compounds of all capillary columns such as injection, applied pressure inlet of column, gas flow rate as well as the conditions of the efficient separation.The order of elution and resolution of compounds on various stationary liquid phases were normal chromatographic behavior which is decrease in specific retention volumes with increase of column temperature through the relationship between logarithm of specific retention volume for the studied compounds against reciprocal of absolute column temperature which is observed generally linear relation for all compounds on different liquid phases by using (Clausius - Clapeyron) , then calculate the thermodynamic parameters ?H0 , ?S0 and ?G from the slope and intercept respectively the negative values of partial molar enthalpy ?H0 of solutions indicate to highest interaction between liquid phases and separated compounds. The results show that the zebron (FFAT) consider the high negative value of ?H and the reaction was exothermic, on other hand the highest negative value of ?s means less random of solutes on some liquid phase , so it was more selective towards to prepared azo derivatives of p - cresol.

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.

During the period from October 2013 to February 2014, a total of 140 oral swab were collected from immunocompromised patients with attending to the three center in AL - Sadder Medical City (Oncology center and kidney center and Center for Diabetes and Endocrinology).In AL - Najaf Governorate, the samples were collected as following : - 110 mouth swabs from patients suffering from leukemia, prostate, stomach and bowel cancer, also 10 mouth swabs from kidney transplant patients and 20 mouth swabs from diabetes. The percentage of female to male was as following, female (86) 64(72.7%) infected, 22(42.3%) uninfected and male (54) 30(57.7%) uninfected, 24(27.3%) infected, with age range between (5 - 64) years. In this study, the results show that the incidence of candidiasis in women was higher than the male also the most cases of candidiasis in patients age range between (45 - 54) years. The results of the present study reveal that the prevalence of oral candidiasis from patient with cancer was more than diabetes & kidney transplant patients which was 72(81.18%), 12(13.65%) & 4(4.54%) respectively. When culturing oral samples on the primary isolation media Sabouroud dextrose agar (SDA) and the secondary media on CHROM agar, The results reveal the presence of 88 isolates belong to Candida spp.which include : - 42 (47.68%) belong to Candida albicans, 20 (22.72%) belong to Candida. dubliniensis, 18 (20.5%)belong to Candida krusei, 6 (6.8%) belong to Candida glabrata & 2 (2.3%) belong to Candida parapsilosis. According to this result, Candida albicans was found the most frequently isolated species and the occurrence of the other non - albicans isolates such as Candida dubliniensis and which followed Candida albicans in frequency of the isolates in oral candidiasis. In this study, the ability of C.albicans & non - albicans was tested to produce some virulence factors such as production of enzymes phospholipase, lipase, germ tube, chlamydospore & biofilms when culturing Candida spp. on different media. The results of the culture show that Candida albicans produces all virulence factor included germ tube, chlamydospore, biofilms & phospholipase. Some species share several phenotypic characteristics ability to produce enzymes of phospholipase such as C.krusei while C.dubliniensis produce chlamydospore, when culturing in the Casein agar & produce biofilms, In addition the molecular tests to was used for Candida albicans confirm the ability to secreted aspartyl proteinase (ASP2). This study showed the amplified from the Candida spp. as following : - C.albicans 306 bp, C.glabrata 594 bp, C.parapsliosis 387 bp, C.krusei 651 bp & C.dubliniensis 451 bp.

Abstract: اجريت الدراسة الحالية في محافظة النجف في الفترة الممتدة مابين شباط 2012 لغاية تشرين الثاني 2013 في العيادة الاستشارية للجلدية في مدينة الصدر الطبية وكليتي العلوم والتربية للبنات في جامعة الكوفة. كان عدد المصابين بالجرب الذين ارتادوا العيادة الاستشارية لل | The present study was carried out in Najaf governorate, during the period from February 2012 till November 2013 in Dermatology Outpatient Clinic in Al - Sader Medical City, College of Science and College of Education for Girls in Kufa University. 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: يعد الكبد العضو الرئيسي المسؤول عن ازالة السموم في الجسم, مما يجعله الاول في التعرض للسمية الدوائية والكيميائية للمواد الداخلة للجسم من جميع الاعضاء, ووفق ذلك اجريت هذه الدراسة لمقارنة التاثير الحامي للكويرسيتين ومستخلص الحلبة على الانسجة الكبدية لذكور ال | The liver is the main organ responsible for removing toxins in the body, making it the first to face various chemicals from all of the organs, and according to this the study had designed to compare the hepatoprotective effect of the Quercetin and Trigonella foenum graecum extract on the liver tissues of male rats poisoned with carbon tetrachloride, and to know their effects when used together. The study was conducted at the Faculty of Pharmacy - University of Kufa, and included using of 30 rats from Sprague - Dawley divided into five groups : the negative control group, the positive control group, the group treated with organic extract, the quercetin treated group and the group treated with extract and quercetin together. The period of dosing continued for 7 days and on the eighth day all groups(except the control group) were poisoned with carbon tetrachloride. After 24 hours the animals were killed. The study lasted from April 2013 - until July 2013. The Liver weights of treated animals were measured, the effectiveness of transferase enzymes Alanine Transaminase, Aspartate Transaminase and Alkaline phosphatase and total bilirubin level in the serum were assessed, also the Glutathione and Malondialdehyde levels were estimated in liver homogenized. The results showed the following : A significant increase (P<0.05) in the liver weights, the effectiveness of the amine transferase enzymes, Alkaline phosphatas and total bilirubin in the serum of the treated animals when compared with the negative control group, while these parameters revealed a significant decrease (P<0.05) at the treated groups as compared with the positive control group. The results showed no significant difference (P>0.05) in the Glutathione level and a significant increment (P<0.05) in the level of Malondialdehyde in the treated groups when compared with the negative control group. Also, the results showed a significant decrease and increase (P<0.05) in the levels of Glutathione and the Malondialdehyde at the treated animals as compared with the positive control group. The present study showed numerous histological changes which resulted from the injection with carbon tetrachloride. In relation with the tissue sections which have been taken from the treated groups : with the extract, quercetin and the group treated with both revealed a protective effect for organic extract seeds of Trigonella foenum - graecum and quercetin drug on the liver tissues which had been poisoned and the best effect in the protection appeared at the group which was treated with the extract and quercetin together. From this study we can conclude that the Trigonella foenum - graecum organic extract and quercetin may reveal a protective role for the liver against carbon tetrachloride poisoning by maintaining the effectiveness of liver enzymes Alanine Transaminase, Aspartate Transaminase and Alkaline phosphatase and bilirubin level in the serum as well as by increasing the Glutathione level and falling the Malondialdehyde level in liver homogenized. Also we conclude that using Trigonella foenum - graecum organic extract and quercetin together led to double protection of the liver and efficiently as a result of the positive impact which resulted from using them together

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.

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: شملت هذه الدراسة فحص 150 عينة من السائل المنوي لمرضى القيلة الدوالية Varicocele والاشخاص الخصبين بعد مدة امتناع قدرها 3 - 5 ايام حيث جمعت العينات في مختبرات مركز الخصوبة / مدينة الصدر الطبية / محافظة النجف الاشرف من 1 / 10 /2012 الى 30/ 4 /2013, لقلة الدر | This study was included 150 samples of semen for varicocele and fertile persons. The samples were collected after 3 - 5 day abstinence period at fertility center Laboratories / ALsader Medical city in An Najaf province.For the period from 1/10/2012 to 30/4/2013.Because the studies about varicocele are rare, the present studies aimed to know the impact of varicocele on semen and sperm parameter, sperm quality index, Malondialdehyde concentration and the percentage of sperm DNA integrity.So, this study was aimed at investigation wethere the Varicocelectomy in varicocele patients could positively influence studied parameters.The research was involved examining 83 sample of seminal fluid for varicocele patient. The percentage of varicocele grades were examined and the results were represented 40% grade1, 39% grade2 and 21% grade3.The result were showed a significant decrease (P<0.05) in sperm concentration , progressively motile sperm, normal sperm morphology percent and sperm viability percent for varicocele patient compared with the fertile persons, while there was noticed a significant increase (P<0.05) in Round cells concentration snd liquefaction time for varicocele patient compared to fertile person and the result of this study were showed significant decrease (P<0.05) of sperm quality index and sperm DNA integrity for varicocele patient compared to fertile persons (control).The study noted to the significant increase (P<0.05) of malondialdehyde concentration for varicocele patients compared to fertile persons. The coefficient factor was used to investigate the correlation between malondialdehyde concentration and the studies parameter.there was increase correlation (P<0.05) between malondialdehyde concentration and sperm concentration(r= - 0.86 P<0.05) progressively motile sperm (r= - 0.938), normal sperm morphology percent (r= - 0.90 P<0.05), sperm viability percent (r = - 0.846 P<0.05) and sperm quality index (r = - 0.836 P<0.05), while there was (P<0.05) positive correlation between malondialdehyde concentration and semen volume (r=+0.822 P<0.05), liquefaction time (r = +0.828 P<0.05) and round cells correlation (r= + 0.89 P<0.05).Also the coefficient was used to study the correlation between sperm DNA integrity and other study parameter. The results of this study were showed positive correlation between the percentage of DNA integrity and sperm concentration (r= +0.88 P<0.05), progressively motile sperm (r=+0.78P<0.05), normal sperm morphology (r= +0.86 P<0.05), sperm viability percentage (r=+0.87 P<0.05) and sperm quality index (r= +0.81 P<0.05), while it was noticed in used correlation between sperm DNA integrity and malondialdehyde concentration (r= - 0.681 P<0.05), semen volume (r= - 0.67 P<0.05), liquefaction time (r= - 0.65 P<0.05) and round cells (r= - 0.54 P<0.05). The effect of varicocele grading on sperm and semen parameter, sperm quality index, malondialdehyde concentration and percentage of sperm DNA integrity was studied, the result were showed a significant decrease (P<0.05)of sperm concentration, progressively motile sperm, sperm viability and normal sperm morphology percentage, and a significant increase (P<0.05) of liquefaction time and Round cells concentration for varicocele patients grad1, grade2 and grade3 compared with the fertile persons. and when we are compare between varicocele patient according to type of grade the results were show a significant decrease (P<0.05) of sperm concentration, progressively motile sperm and normal sperm morphology percentage and a significant increase (P<0.05) of liquefaction time for varicocele patients grade2 and grade3 compared to grade1 varicocele patient.So the result showed a significant decrease (P<0.05) of sperm concentration for grade3 varicocele patients compared with the grade2 varicocele patients. The result of this study were showed a significant decrease (P<0.05) in sperm quality index and sperm DNA integrity for grad1, grade2 and grade3 varicocele patients compared to fertile persons. also it was noticed a significant decrease (P<0.05) of sperm quality index and sperm DNA integrity for grade2 and grade3 varicocele patients compared to grade1 varicocele patients but the malondialdehyde concentration according to varicocele grade, the result were showed a significant increase (P<0.05) of malondialdehyde concentration for grade2 and grade3 varicocele patients compared to grade1 varicocele patients and fertile persons. In this study the effect of Varicocelectomy on study parameters was studied and the result were showed a significant increase (P<0.05) of sperm concentration, progressively motile sperm, sperm viability percentage, normal sperm morphology, percent, sperm quality index and sperm DNA integrity and a significant decrease (P<0.05) of liquefaction time and malondialdehyde concentration for Varicocelectomy compared to varicocele patients. The result were showed a significant decrease (P<0.05)of sperm viability percent, normal sperm morphology percent, sperm DNA integrity and sperm quality index and a significant increase (P<0.05) in round cells concentration, liquefaction time and malondialdehyde concentration for Varicocelectomy patients compared to fertile persons.From the result of present study, we are concluded that varicocele has been negatively impact on sperm and semen parameters, malondialdehyde concentration and sperm DNA integrity, and the effect of varicocele is associated with the increasing of varicocele grading, while Varicocelectomy has been positive impact on sperm and semen parameters, malondialdehyde concentration and sperm DNA integrity but this result have not reached to similar state to fertile persons

Abstract: هدفت الدراسة الحالية الى تقييم النسبة المئوية لكروماتين النطفة غير السوي Abnormal sperm chromatin percentage لمرضى عديمي الخصوبة مقارنة بالرجال الخصبين ودراسة العلاقة بين النسبة المئوية لكروماتين النطفة غير السوي ومعايير المني ومؤشر نوعية النطف وتركيز الم | The aim of the current study was to evaluate the Abnormal sperm chromatin percent for the infertile comparing with the fertile men and study the relation between the Abnormal sperm chromatin percent, the sperm and semen parameters, sperm quality index and MDA concentration for the infertile normozoospermic and asthenozoospermic patients comparing with the fertile men.This study was conducted in the laboratories of fertility centers in Al - Sader medical city/ Al - Najaf Al - Ashraf from 1 / 11 / 2012 to 30 / 4 / 2013.By the end of the semen liquefaction time, the 72 samples were divided into two groups : - the fertile men, (17), and the second is represented by the Infertile Normozoospermic (23) and the Asthenozoospermic (32). The age average was (1.36±30.9) , (0.98 ±29.6) and (1.63± 31.4) years respectively. The samples were restricted to the non smoking patients only. The study results show a significant (P< 0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the sperm viability percent and the semen volume, and a significant (P<0.05) increase in the round cell concentration, liquefaction time, Malondialdehyde concentration and the percent of the abnormal chromatin of the Normozoospermic and the Asthenozoospermic patients comparing with the fertile men. The results also show a negative correlation (P<0.05) between the (MDA) concentration and the parameters represented by the sperm concentration, percent of the progressive forward movement sperm, the normal sperm percent, the sperm viability percent sperm quality index and semen volume. While it had been noticed that there was a positive relation between the MDA concentration and the parameters represented by the sperm liquefaction time, round cell concentration and the abnormal sperm chromatin percent of all the study groups. In this research the relation between the sperm chromatin damage and the other study parameters had been studied by dividing the samples according to the degree of chromatin damage. The results show a significant (P<0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the normal sperm percent, the sperm viability percent, the sperm quality index and semen volume, with a significant (P<0.05) increase in the liquefaction time and round cell concentration (MDA) concentration and the percent of the abnormal chromatin of the group (> 10) comparing with the group (? 10) for the fertile men, also the results show a significant (P<0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the normal sperm percent, the sperm viability percent and the semen volume, with a significant (P<0.05) increase in the liquefaction time and round cell concentration for the group (> 25) comparing with the group (? 25) for the infertile Normozoospermic patients. For the Asthenozoospermic patients the study shows a significant (P<0.05) decrease in the sperm concentration, the percent of the progressive forward movement sperm, the normal sperm percent, the sperm quality index, the sperm viability percent and semen volume, and a significant (P<0.05) increase in the liquefaction time and round cell concentration for the study groups represented by the group (> 20 - 40) and (< 40) comparing with (? 20). From the above results it could be concluded that the increase of (MDA) level resulted from the active (ROS) leads to an increase in the abnormal chromatin percent of the infertile Normozoospermic patients which had a negative effect on the semen parameters which could be a reason for the infertility for those patients

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

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.

This study was also used to know the effect of the extract in normal (healthy) female rats. In this study (54) female rats were utilized which were divided into (9) groups with 6 rats for each group. Diabetes mellitus was induced in (30) female rats, were distributed into 5 sub groups. One of them was considered as control group for the infected rats, and three groups of them were treated with different concentrations of the extract (250, 500 and 750)mg/kg while the fifth group was treated by the chemical drug Glibenclamide (0.6) mg/kg. The other 24 normal rats were also divided into 4 sub groups, one of them considered as control group. And the other three groups were treated with the extract concentrations (250, 500 and 750)mg/kg. The treating period with the plant extract and the drug continued for 30 day.Results of this study were as the following : ? A significant (P< 0.05) decrease was showen in total body weight, insulin hormone and HDL - c levels, total WBC and RBC count in addition to Hb concentration in infected group of diabetes mellitus in comparison with healthy control group.? A significant (P< 0.05) increase was clear in the levels of glucose, TC, TG, LDL - c, VLDL - c, urea, creatinine and ALT and AST enzymes in infected group in comparison with healthy control group.? The healthy rats that treated with the extract concentrations were showed a significant increase in their total body weight at the end period as compared with the first day of experiment, there was also a significant (P < 0.05) increase in body weights of the infected rats that were treated by the two concentrations (500, 750) mg/kg of extract as compared with infected control group.? The infected rats that treated by all three concentration of plant extract and the glibenclamid drug were exhibited a significant (P< 0.05) increase in insulin level as compared with infected control group.? on the other hand, it was also showen a significant (P< 0.05) decrease in glucose level of infected rats that have been treated by the three concentrations and the (0.6) mg/kg concentration of glibenclamid as compared with infected control group.? The levels of TC, TG, LDL - c, VLDL - c were significantly (P< 0.05) decreased, in contrast a significant increase was occurred in the level of HDL - c in infected rats when they treated by all the concentrations of plant extract as compared with infected control group.? The urea and creatinine levels showed a significant (P< 0.05) decrease when the infected rats were treated by the two concentrations (500, 750) mg/kg as compared with infected control group, while in the healthy rats, the urea level showed a significant (P< 0.05) decrease as compared with healthy control group.? A significant (P < 0.05) decrease was occurred in ALT enzyme level when the infected rats were treated by all extract concentrations and the chemical drug. But AST enzyme level was significantly (P < 0.05) decrease when the infected rats were only treated with the two concentrations (500, 750) mg/kg of plant extract in addition to glibenclamid as compared with healthy control group.? The two concentrations (500, 750) mg/kg of plant extract and the concentration (0.6) mg/kg of the glibenclamid drug caused a significant (P< 0.05) increase in total RBC count, and the hemoglobin concentration, while only the larger dose of plant extract caused a significant (P < 0.05) increase in total WBC count in infected rats as as compared with infected control group.In conclusion, the results of this study indicate that the two concentrations (500, 750) mg/kg of alfalfa leaves extract gave a good results, even better than the reference drug, glibenclamid for treating diabetes mellitus, in addition to ameliorate the metabolic disorders that accompany it.

Abstract: تعد الاصابة بقبل الارتعاجPre - eclampsia من الاعتلالات الخطيرة التي قد تظهر في الثلث الثالث من مدة الحمل اذ تتصف هذه الاصابة بارتفاع ضغط الدم وظهور بروتين الالبومين في الادرار. وقد ظلت اسباب نشوء هذه الحالة غير واضحة المعالم, اذ اعزيت بعض من اسبابها الى ا | Preeclampsia is considered as one of the serious complication in the third trimester of pregnancy. It is associated with hypertension and proteinuria. The causes of preeclamptic are still not well understood. Evidences suggested the involvement of metabolic related mutations in the disease. In the current study, the genetic mutations of CBS and MTHFR genes are studied as markers for the diagnosis of preeclampsia. Sixty preeclamptic pregnant women and forty healthy pregnant women as control group diagnosed by the physicians at Azzahra Teaching hospital for obstetrics &pediatrics in Najaf province from December 2012 to August 2013 The poly merase chain reactions technique was used to evaluate the incidence and frequency of C?S &MTHFR mutations. A questionnaire was conducted to obtain the information of the patients and the control group. Genetic mutation were detected by polymerase chain reaction (PCR)and agaros gel electrophoresis. The information indicated that the age of pregnant women, gestation age, previous history of the patients, family history and parity are involved in the pathogenesis of preeclampsia. The results of the present study of preeclampsia showed a significant increase (P ? 0.01) in patients (25 - 34) years old when compared with the other group. where the results found a significant increase (P <0.01) of Preeclampsia occurred during (33 - 39) weeks of pregnancy. And in the patients with previous history for preeclampsia there was significant increase (P<0.001) compared with healthy pregnants. Pregnants with preeclampsia in the family history showed significant increase (P< 0.01) as for women pregnant for the first time showed and significant (P<0.01) and constituted 8% pregnanst with preeclampsia who had diabetes mellitus. The extraction and quantification of cell free fetal DNA (cff DNA) revealed a significant (P<0.0001)increase in preeclamptic patients when compared with those of healthy pregnant women. It is confirmed by the use of an internal negative control through the monitoring of SRY gene (Y chromosome gene) amplification that the gene belong to the infant and 40 pregnant woman were followed up till the labor. Thus, 9 of them had delivered males, while 30 had delivered females. The wild type SRY gene band was obtained clearly from those of male delivery, but not from those of female delivery. Mutations of C?S gene were analyzed by theuse a primer intended to amplify a fragment of171 bp.The rate of mutation was found to be 51.7% and 5% in preeclamptic patients and healthy pregnant women respectively and Odd Ratio=20.31, P value=10 - 7. The C677T mutation of MTHFR gene was verified by the use of a primer designed to amplify a fragment of 198bp. The prevalence of mutation was indicated to be 68.3% and 17.5% in the preeclamptic patients and healthy pregnant women respectively and Odd Ratio =10.17, Pvalue =6.2*10 - 7. Results demonstrated the wide involvement of C?S and MTHFR gene mutation in the pathogenesis of preeclampsia, but they are no crucial for the development of the disease. In addition there are so many factors thatmay be involved in such development.

Atotal of 155 sample from different clinical source has been collected during the period from October - 2012 to March - 2013, these include 20 samples from vaginal smear, 8 samples from saliva and 6 samples from human milk.The results of primary isolation, Laboratory diagnosis and biochemical test showed that 34 isolates has bee identified as L.salivarius.Ahigh precent of isolation has been carried out from human milk which was 40%. The ability of all isolates to produce gelatinase and biofilm has been detected and the results revealed the ability of some isolates to produce gelatinase and biofilm. Ahigh percent of gelatinase production has been detected in L.salivarius isolated from milk sample (50%), while alow percent of gelatinase production was 0% in L.salivarius isolated from saliva. The results of optical density of biofilm produced by L.salivarius isolates from milk which was 100% higher than it in isolates from vaginal and saliva which was 85% and 75% respectively. All isolates shows antibacterial effect against some Gram negative bacteria, the diameter of inhibition as between (2 - 8), the results showed the ability of 4 selective isolates of L.salivarius to produce bacteriocin in which the Rf valve of precipitate bacteriocin was (0.42 - 0.6) compard with leaky bacteriocin hich was (0.57 - 0.8), also leaky bacteriocin as more activity against G - ve bacteria than precipitate bacteriocin. The result of plasmid profile in L.salivarius revealed the presence of megaplasmid in all isolate except one which had one megaplasmid and one small plasmid. Bacterial conjugation between L.salivarius that produce bacteriocin and had megaplasmid which used as adonor cell with E. coli Jm 109 as a recipient cell showed transferring of megaplasmid from donor to recipient cell and the transconjugant cells showed high anti - bacterial effect due to bacteriocin production against G - ve bacteria. The result of amplification of Sal P gene encoding salivracin P by PCR confirmed that all isolate had no Sal P gene in there genetic materials which revealed that these isolates had another type of bacteriocin rather than Salivracin P.

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.

Abstract: ا جريت هذه التجربة في قسم علوم الحياة / كلية العلوم / جامعة الكوفة في محافظة النجف الاشرف وتضمنت مرحلتين : الاولى زراعة البذور لغرض قياس نسبة الانبات للمدة من 1 / 8 لغاية 8 / 8 / 2011 وانتاج الشتلات للمدة من 15/8/2011 ولغاية 14 / 9 /2011 في حقل خاص لانتا | This experiment was conducted in the Department of Biology, College of Sciences, University of Kufa in Al - Najaf Al - Ashraf province. It included two periods : the first was seed sowing to measure germination percentage from 1 - 8 till 8 - 8 - 2011, and transplants production from 15 - 8 - 2011 till 14 - 9 - 2011 in a private farm for vegetable transplants production. The second was transplanting in an open field belongs to Plant Production Department/Kufa Technical Institute from 15 - 9 - 2011 till 17 - 1 - 2012 to measure plant growth parameters and curd cauliflower production cv.solid snow in harmless environment techniques. The experiment was adopted as factional experiment. The treatments were distributed according to Randomized Complete Block Design (RCBD) with four replicates. The experiment included the study of two factors : the first, was five magnetic intensities for treating waters magnetically (0; 500; 750; 1500 and 2500 Gauss) by means of dipolar magnetrons. The second was three quantities of plant organic manure(rice residues).i.e.(0, 2.5 and 5.0 kg/furrow) with a length of 6.5 m. and their interactions on growth and production the yield of cauliflower, cv.solid snow. Duncan's Multiple Range Test (DMRT) was used to compare means at probability of0.05. Correlation and regression coefficient were also used to evaluate the relationships between studied parameters and time. Vegetative growth parameters that are measured were : plant leaf number ; stem height; stem diameter; plant leaf area; leaf fresh and dry weight; stem dry weight; plant shoot fresh and dry weight. Flowering parameters were : curd fresh and dry weight and curd diameter. The results could be summarized as following : 1. Water chemical analysis showed that irrigation with magnetized treated water had an effect on physical properties, nevertheless, was more or less affected ions components. 2. The use of magnetized treated water in irrigation resulted in an increase in germination percentage of cauliflower seeds cv. Solid snow.The highest germination percentage was obtained from magnetic intensity of 1500 Gauss in both experiments, laboratory and field that reached 71.14 and 65, 62%, respectively on the base of Arc Sin. 3. The use of magnetized treated water in plant irrigation at all the used intensities resulted in an early emerged curd cauliflower by 15 days compared with control treatment plants. 4. 750 gauss magnetized treated water achieved at age of 138 days from transplanting, the highest plant leaf area mean is (4836.2 cm2) with percentage increase of 51.7% compared to control treatment plant leaf area (3188.3 cm2).That effect was reflected on curd weight. 5. 1500 and 2500 Gauss magnetized treated water treatments at earlier ages increased the values of vegetative growth parameters which reflected its effect on flowering growth parameters by shorter time of curd irritation, compared with the effect of 500 - 750 Gauss at earlier ages , which are in spite of its late effects produced at 150 days old from transplanting particularly 750 Gauss the highest mean of curd fresh weight. 6. 750 Gauss magnetized treated water achieved the highest yield reached 22.2 ton/h. which differed from that productivity gained from control treatment plant(9 - 29 ton/h.) with percentage increase of 138.8%. 7. Organic plant manure addition at both quantities(2.5 and 5.0kg/furrow) resulted in an increase in both vegetative and flowering growth parameters compared with untreated plants. 5 kg/furrow treatment produced the highest means compared to control treatment particularly at the age of 138 days in all vegetative growth parameters. 8. The addition of 5 kg/furrow at age of 150 days produced the largest curd fresh weight 918.4 g. and diameter of 17.2 cm which statistically differed to compared plant treatment that produced 506.0 g. and 13.3 cm. for curd fresh weight and diameter at the same age respectively. 9. 5 kg/furrow organic manure addition resulted in a highest productivity of 21.6 ton/h. compared to that of control treatment of 11.9 ton/h. with an increase of 81.5%. 10. Interaction between irrigation water magnetically treated with 750 Gauss and addition of (organic manure with 5 kg/furrow) at the age of150 days resulted in the highest curd fresh weight of 1292.9 g. with curd diameter of 20.3 cm. compared to that plant of control treatment produced curd fresh weight of 292.5 g. and 11.0 cm. diameter. This interaction also produced 30.3 ton/h. for (750 Gauss×5 kg/furrow) compared with the productivity of control treatment plants that gave 6.86 ton/h. with percentage increase of 341.6%

Abstract: اجريت هذه الدراسة على 150 مريضا الراقدين في مستشفى الصدرالتعليمي ومستشفى الحكيم (قسم الكلى) في محافظة النجف خلال الفترة الممتدة من كانون الاول 2012 الى شهر اب 2013. وكان الغرض من هذه الدراسة بيان علاقة الفيروس المضخم للخلايا بمرض الفشل الكلوي، تراوحت اعما | This study was carried out on 150 renal failure patients, who were admitted to the kidney department in AL - Sadder Medical City and Al - Hakeem hospital in AL - Najaf governorate during the period from December 2012 to August, 2013. Subjects of this study were Investigated for the role of Cytomegalovirus among them, their age ranged between (1 - 88) years. Twenty four (age - and sex - matched) healthy individuals without any evidence of chronic inflammatory disease depended as control. All patients and control divided in four age groups. Blood and urine samples were collected from patients and control for immunological (IgM, IgG, C3, C4, IL - 6, IL - 10, IL - 12 & IFN - ?) by using ELISA and molecular study by RT - PCR, respectively. The obtained results showed that HCMV - IgG antibody was 100% for all cases, while IgM was 18.66% compared with that of control. Real time - PCR amplification for presence of HCMV DNA in urine samples revealed that HCMV genome were detected in 22(14.66%) of the 150 urine samples in all age groups, that distributed into 12(21.05%) with viral load ranged (20 - 543840) Copy/ml in females and 10 (10.75%) with viral load ranged (40 - 28050) Copy/ml for males. The results of cytokines profile showed a highly significant(P<0.05) elevation in patients than control. According to sex females appeared higher IFN - ?, IL - 6, IL - 10 ( 83.86, 82.67, 9.06 pg/ml, respetively) than males were (76.57 , 79.36, 6.51 pg/ml, respectively). Where's IL - 12 were recorded higher elevation in male (28.83 pg/ml ) than females (27.35 pg/ml). According to age groups 41 - 60 age group showed high level in IFN - ?, IL - 6, IL - 10 were (96.45, 90.40, 9.62) pg/ml , respectively.While IL - 12 appeared high level (37.43 pg/ml ) in age group 1 - 20 years Complement fractions C3, C4 decreased in all groups of patients compared to those of a healthy control. C3 was recorded (64.37 mg/dl) in females, and (70.24 mg/dl) in males and decreased to (63.41 mg/dl) in age group (1 - 20) years, while C4 decreased significantly among sex it was (21.06 mg/dl) in females and(24.22 mg/dl) in males, and down to (21.65 mg/dl) in age group (21 - 40) years.The overall finding results showed that HCMV are more prevalence among chronic renal failure patients and cause immune suppressor for them by increase and decrease many immune factors.

Abstract: The study aimed to investigating the role of coagulase - negative staphylococci in human infections, and determining the predominance genes of the virulence factors. Three hundred clinical specimens were collected from out and inpatients undergoing catheter related infections and twenty specimens were collected from healthy hospital staff as a control from January 2013 to July 2013 of Al - Zahraa Teaching Hospital, Al - Sader Teaching Hospital and Al - Hakeem Hospital in Al - Najaf Al - Ashraf province. The specimens were included urine, blood, vaginal swabs, seminal fluid and wound swabs. The specimens were cultured on mannitol salt agar and the primary identification was depended on Gram stained and biochemical tests. Then finally identification with Vitek 2 system is done.One hundred isolates were identified as coagulase - negative staphylococci (CoNS), Staphylococcus haemolyticus was identified as the most frequently isolated species in (53%), followed by Staphylococcus epidermidis (26%) and Staphylococcus hominis were recorded in (21%). Most of CoNS isolates were highly resistance to penicillin G (benzylpenicillin), oxacillin, cefoxitin and erythromycin; and low resistance to rifampicin, levofloxacin and others. While, control isolates results showed moderate resistance to penicillin G and erythromycin; low - level of resistance to cefoxitin, oxacillin and other antibiotics.The investigation of virulence factors revealed that 93% of coagulase - negative staphylococci isolates were production of slime layer, DNase 58%, protease 29% and hemolysin 88%. But the results gave negative result for TNase and lipase enzymes.Monoplex and multiplex PCR were used to explore the MecA, aap, icaA, icaD, atlE, sea, seb, sec, sed, hla, hlb, sspA, sspB, geh, nuc genes. The results showed that all CoNS isolates (100%) had mecA and atlEgenes, but 98% of isolates had aap, 93% icaA and icaD genes. PCR revealed that only (14%) of isolates had genes for enterotoxins expression. (92.86%) and (7.14%), sea and seb respectively, in contrast, the sec and sed genes were not be recorded.The result showed that 47% of CoNS isolates had hla gene and 41% contain hlb gene, 29% were positive for the sspA gene whereas the sspB gene and geh and nuc2 genes not found in any of staphylococcal isolates. Finally, the result indicated that 58% of CoNS isolates were expressed the nuc1 gene.Plasmid curing was carried out in order to determine the origin of resistance and some virulence factor genes (chromosomal or plasmid - borne gene). The curing (elimination) of the plasmids of coagulase - negative staphylococci isolated was catalyzed using ethidium bromide in different concentration and high temperature (44?C). The results showed that the oxacillin resistant coagulase - negative staphylococci were plasmid mediated since 93% of the isolates showed negative result on oxacillin resistance screening agar, and absence of mecA gene from all isolates. Also, 41 of coagulase - negative staphylococci isolates that showed ? - hemolysin became non - hemolysin after manipulated with ethidium bromide.Finelly, taking into consideration the etiological importance of CoNS has often been neglected, the present investigation confirmed that these microorganisms should not be ignored or classified as mere contaminant.

Abstract: تضمن الفصل الاول التعريف بالبحث واهميته في استخدام تمرينات دورة الاطالة والتقصير وعرض النموذج باستخدام تقنيات الحاسوب في تطوير القدرة العضلية للذراعين والرجلين ودقة التصويب من القفز بكرة اليد، اذ تعد لعبة كرة اليد واحدة من الالعاب الرياضية الجماعية المهم | First Section : Definition Research This approach identifies and its importance by using stretching and shortening exercises and presenting the sample by using the computer in developing the muscle ability of the arms & the legs, and accuracy of some kinds of targeting from a Jumping Position with the handball. The handball game is one of the sport games taught at our physical education colleges. It is considered one of the most popular worldwide sport, which has local and continental championships. The player of handball has many physical specifications including (strength and duration and flexibility and correspondence), and many skills including using one arm with the ball and the other without it, that is (targeting and dripping, passing and deluding and other skills). Therefore, the new training view has become taking care of everything that make it possible to achieve goals through using more specialized mean of training like exercises of the cycle of stretching and constricting which has a deep effect in developing the muscle ability because it has a great importance to the player of handball in using this ability continuously during performing skills of defense and attack representing in the muscle ability of the arms and the legs. The problem of the Research is represented in the abstaining and weakness of the female team of the university especially in performing some kinds of the targeting from a jumping position, both in its high and frontal poses. The reason of being unable to perform these kinds of targeting is failure of the ball's crossing of the defense line or reaching the goalkeeper in a weak impetus and thus makes it easy to catch or push it away. The Objective of the Research can be summarized as follows : - Getting acquainted with effectiveness of cycle of stretching and shortening in developing the muscle ability of the arms and legs of the girls' university team of handball. - Getting acquainted with effectiveness of presenting the sample by using the computer in developing accuracy of performing some kinds of targeting from a jumping position performed by the girls of the handball team of the university of Kufa. The Impose Research : - - There are differences having statistical connotation between the prior and the afterwards experimentation and to the favour of the afterwards experimentation regarding exercises of the cycle of stretching and shortening in developing the muscle ability of the arms and legs of the girls' Kufa university team of handball. Areas of the Research : - The human Area / the girls' Kufa university team of handball. - The duration Area / from 1 December, 2013 till 1 June, 2013. - The spatial Area / the stadium of the College of Education for Girls / University of Kufa.Second Section : The Theoretical Studies & the similar Studies This approach deals with the special theory regarding the research varieties where, the concept of exercises of the cycle of stretching and shortening and the subjects correlated, and the concept of the muscle ability and targeting skill of handball and its kinds of jumping, and the importance of computer techniques and its uses in learning and teaching, taken into account. The similar studies were also taken into account.Third Section : Methodology of the Study and its Field Processes : The empirical method was chosen in accordance with the nature of the problem. The sample was chosen on purpose from the team of handball of the University of Kufa, and it was divided into two groups each of (10) female players. They got equivalence and accordance before starting the training course through a prior experimentation as a means of collecting information; then an empirical method of the cycle of stretching and restriction was presented, and the sample was presented by the computer techniques for 8 weeks, and an afterwards experimentation was done to get the results which were treated statically through using (SPSS), and which enabled the researcher to recognize the differences concerning the research varieties between the two groups. Fourth Approach : presenting the results and analyzing and discussing them This approach includes the total presentation of all the results through diagram columns and tables and analyzing and discussing them scientifically through using the athletic training literature and learning to achieve the research goals and assumptions.Fifth Section : Conclusions and Recommendations The researcher has reached a number of important conclusions, some of thedm are : - The cycle of stretching and shortening has a positive effect in developing the muscle ability of the arms and legs in the empirical sample of the research. - The presenting of the type by using computer techniques has a positive effect in developing accuracy of targeting from a jumping position of the research empirical sample. - The time of the independent variant represented in the training doses was suitable in creating adaptations expressing the range of development in the muscle ability of the arms and legs and accuracy of targeting from a jumping position.Some of the important recommendations - Generalization of the course concerning exercises of shortening and stretching and presenting the type by using the computer techniques on the athletic teams of the handball team of the University of Kufa, and the sport clubs outside the university. - Using the training course of the cycle of stretching and shortening (as a physical part) and the computer techniques in presenting the type (as a feedback nutrition) of the other athletic games inside the university and the sport clubs outside the university. - Designing and shortening a number of experimentations to measure accuracy of targeting from jumping forwards with the ball in hand which will be more objective in measuring this skill in the girls
