المستخلص: 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.

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

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

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

المستخلص: The aim of This study is to determine the prevalence of OXA ? - lactamase in pseudomonas aeruginosa isolates from clinical and other environmental cases in Al - Diwaniya Teaching Hospital using phenotypic and molecular methods.The Samples of the study were collected from various sources and they were 390 samples for the period from November 2011 to March 2012, and they includ (292 clinical specimens and 98 environmental sample), the results of cultural and biochemical tests showed that 50 isolates (39 of them were from clinical cases and 11 were from environmental samples), belonged to ps. aeruginosa, and their diagnosis were confirmed by 16s - ribosomal RNA, and the study showed that all the isolates containing the 16s - ribosomal RNA gene, which represents the designed diagnostic gene in this study.The results of this study showed that the higher rate of P. aeruginosa isolates was due to burns infections (23.68 %) , followed by respiratory tract infections (sputum) that were (15.38 %) and then the case to otitis media infections (12.5 %), and lastly that due to urinary tract infections (10.49 %), while the rate isolation from the environmental samples was (5.11 %) from the floor of burns department, followed by (10.8 %) from the medical instruments of department workers.It was noted from this study that the age and gender of the patients have some effect on the infection by P. aeruginosa it was recorded that the higher rate of infection was in patients older then 61 year old, and regarding gender, it was found that females are more infected than male, especially in urinary tract infections. The study showed that there is high rate of infection in the admitted patients, in older people and in those who need urinary catheterization, in addition to those with severe burns and those in the intensive care units. Drug sensitivity test had been carried out for all the bacterial isolates to 22 types of antibiotics by disk diffusion method of Kirby - Bauer, and this study had indicated that there was relatively high resistance from P. aeruginosa to ? - lactam antibiotics, aminoglycoseides, and fluoroquinolone. The results also showed that the studied isolates has possibility of producing broad - spectrum ? - lactames enzymes, and this is supported by the resistance of this bacteria to the third generation cephalosporins and to Alaztronam, it was also shown that there was difference in the resistance to carbapenems antibiotics, the resistance rate to imipenem and meropenem were 16% and 64 %, respectively. Polymyxin B and Polymyxin E also called (Colistin) antibiotics were also used, and the resistance rate %0 for Colistin and %4 for Polymyxin B, that means there was two isolates which are resistant to Polymyxin B and this resistance was a challenge to the success of therapeutic efforts. this study noted that there was 22 (44%) isolates which were resistant to at least three types of antibiotics, and regarded as multi - drug resistant (MDR) and Extensive - drug resistance (XDR) isolates were26 (52%) which was the higher rate among the three types of resistance, The third type of resistance was 2 (4%) which represents the resistance to all types of studied antibiotics (PDR). The ability of these isolates to produce broad - spectrum OXA ? - lactames enzymes groups was investigated thrrough detection of presence of genes blaOXA - 10, blaLCR - 1, blaOXA - 18, blaOXA - 1, blaOXA - 2 in these isolates by using the polymerization chain reaction enzyme technology] (PCR) it showed 50/50 (100%) isolates contain blaOXA - 10 gene, which belongs to the OXA group I, and the results of this study showed no amplification results for blaOXA - 18, blaLCR - 1, blaOXA - 1, blaOXA - 2 genes, which belong to the main groups of broadspectrum OXA ? - lactames enzymes which are OXAgroup II, OXAgroup III and OXA groupV respectively except OXA18 enzyme
