اجريت هذه الدراسة للتعرف على أنواع متفرعة اللوامس وانتشارها في نهر الكوفة , وتأثير العوامل البيئية على تواجدها , اذ جمعت عينات الدراسة شهرياً للمدة من تموز 2023 ولغاية شباط 2024 من ثلاث مواقع , الاول : تقع شمال جسر الامام علي (عليه السلام) والثاني جسر الكوفة القديم (قرب دار الضيافة ) والموقع الثالث جسر ال عيسى (قرب مبزل ميسان ) , اذ قيست العوامل البيئية الفيزياوية والكيمياوية مثل درجة الحرارة والاس الهيدروجيني والتوصيلة الكهربائية واجمالي المواد الصلبة والاوكسجين المذاب والمتطلب الحيوي للاوكسجين وأيون الكالسيوم والعسرة الكلية والعكورة والملوحة . تراوحت الحدود الدنيا والعليا لحرارة الماء (13.9 – 33.2) مْ وكانت العلاقة بين كثافة متفرعة اللوامس ودرجة الحرارة أيجابية والاس الهيدروجيني (6.5 - 8.1) وكانت العلاقة بينهما سلبية والتوصيلة الكهربائية (920 – 1595 ) مايكروسيمنز/سم وكانت العلاقة بينهما أيجابية واجمالي المواد الصلبة ( 507 - 810) وكانت العلاقة أيجابية بينهما وعمق الماء ( 2.3 – 6.5 ) م وكانت العلاقة سلبية بينهما . تم تشخيص 19 جنس تعود الى 3 عوائل من رتبة متفرعة اللوامس من القشريات الصغيرة , وهي Bosminidae ,Chydoridae , Daphniidae أذ وجد أن عائلة Chydoridae هي الاكثر كثافة وغزارة في مواقع الدراسة . أظهرت نتائج التحليل الاحصائي وجود علاقة أرتباط أيجابية أو سلبية بين كثافة متفرعة اللوامس والعوامل البيئية الفيزياوية والكيمياوية المقاسة شهرياً خلال الدراسة , كذلك لوحظ وجود فروق معنوية بين الاشهر ومواقع الدراسة بالنسبة لكثافة متفرعة اللوامس والعوامل الفيزياوية والكيمياوية عند مستوى P< 0.05

The current study was designed to demonstrate the protective impact of vitamin C against some fetal and neonatal congenital malformations and antiinflammatory non-steriodal–induced hepatotoxicity in them of white rats ,this study was carried out in animal house of biology department in Education Faculty for Girls -Kufa university from 1/11/2019 to 15/3/2020, 24 white female rats with age ranged between (11-12) weeks and weights ranged between (230-240) kg, in adition to (24) white male rats with ages between (9-11) weeks for mating, the female and male rats were placed together for mating, after obtaining the required number of pregnant female rats, these pregnant rats were distributed to 4 groups , each group included 6 pregnant rats ,the group1 was treated with normal saline solution and was the control group, group2 was treated with indomethacin drug with a concentration of 8.40 mg / kg of body weight, while group 3,4 were treated with vitamin C with a concentration of 85 mg /kg of body weight and vitaminC with a concentration of 85 mg / kg of body weight + indomethacin drug with a concentration of 8.40 mg / kg of body weight respectively, pregnant female rats in all groups were treated orally from the first day of pregnancy, 3 pregnant rats were dissected during 20 days of pregnancy, while the remaining 3 pregnant rats were left to after birth of each group. The results of the this study pointed to that a significant decrease (P <0.05) in numbers of total and living of the embryos for pregnancy period (20) days and newborns

Abstract The effects of the antiepileptic drug depakine on some embyronicreproductive parameters and hepatic- histopathological changes of the embyros of pregnant female rats treated with this drug during pregnancy were investigated. 10 female albino rats of the Sprague dawley strian were divided into two groups, each group contained 5 pregnant female rats: group 1 was as control group and treated with the normal saline, while group 2 was treated with the drug depakine with the therapeutic dose (1.78 mg / kg of body weight) from the 4th day of pregnancy to the 18th day of it, on the 19th day of pregnancy the pregnant rats were sacrificed , thelivers and uterine horns were removed from the body to study the embyronicreproductive parameters, then the embryos were sacrificed and their livers extracted,the livers of pregnant female rats and embyros were fixed with formaline for histological procssing and the assessment of stimulating histopathological effects by this drug. The results from present study showed a significant decrease (P <0.05) in weight gain of pregnant female rats , numbers of total and living embyros and the weights of the body and placenta and lengths of toal body and limbs(hands and feet) of embyros , while the results pointed to a significant increase (P <0.05) in the absorbed and dead embyros and the skeletal system of embyros suffered from many malformations during pregnancy period of 18 days in treated rats group with depakine drug comparing with control group, and the hepatic- histological study of the pregnant female rats and embyros indicated normal hepatic-histological structure of animal rats during pregnancy period of 18 days in control group , while experimental rat group treated with depakine drug signified various patho-histological changes in livers of the pregnant female rats and embyros of the same pregnancy period .

The study involved the isolation of enterococcus bacteria and diagnosis of different types of diseases, where (190) samples of cows suffering from different diseases were obtain (34) (18.1%) isolation of Enterococcus were divided into 21 (15.6% ) Of the blood, 8 (52.4%) and 3 (17.6%) of the vagina, but not isolated from the spinal cord samples. The study was conducted on 2 isolates from the blood samples to become the number of isolates (36 isolates). And the study showed that type E. Faecalis was the most common species, with 75% followed by E. faecium (20.2%) and E.galinarium (4.8%), which also revealed the virulence factors of these bacteria, which play an important role in their disease. Bacteria have the ability to produce Haemolysin, Protease, Lipase, ß-Lactamase, and the formation of capsules and their ability of Haemagglutination and of the effect of mannos on this process.
