التشوهات الخلقية في اجنة الفئران السويسرية البيضاء من امهات معاملة بجرع مختلفة من عقار Mus masculus الديكساميثازون Developmental anomalies in swiss albino mice embryos Mus masculus from the mother treated with different doses of Dexamethasone

المستخلص: The current study was conducted for the period from September 2015 until August 2016 in college of Education for Pure Sciences - University of Thi - Qar, this study aimed to fallow the embryonic lung development and evaluate histological changes in embryos's lung development when pregnant mice treated with different doses of Dexamethasone (Dex) and evaluate Alpha - fetoprotein (AFP) levels were evaluated as an indicator for congenital malformations. Sixty pregnant mice were randomly divided into four groups and each group contain 15 pregnant mice. The members of each group were given specific dose of Dex and at different time periods, while the control group injected with a solution of Normal Saline 0.9%.All animals received doses used by tail intravenous injection until the end of the time periods specified .Blood samples were taken for the purposes of biochemical parameters account as well as the collection of samples for histological study .The treatment of animals under the same conditions were determined with a dose based on body weight, according to what was stated in the pharmaceutical constitutions where's the therapeutic dosage was 0.002 mg \2mg (0.1mg.kg from body weight ). We used another two concentrations from drug ,one less than the therapeutic dosage (0.05mg \kg from body weight) and another more than the therapeutic dosage (0.2mg \kg from body weight ).The results have showed that was a negative effects on mice embryo's body weights and the lengths increase with increasing of number and doses concentrations. The using of different doses of Dex also showed various changes in general external morphological features and congenital malformation in embryos of treated mothers included : Death of embryos ,placenta damage ,neural Tube Defect ,Trunk Torsion ,Headhemorrhage, Brain hypertrophy ,Liver Hypertrophy ,Letter C Shape Embryos, swelling ,Convoluted Tail ,Short nostril and limbs, curved head, Wrinkled skin ,Crooked pave ,Short toes ,Seal legs appearance, Oedema ,absent fingers and eyelids ,Tail congestion and Bulging eyes. Histologically microscopic examination showed histological changes with varied severity and appearing between different sub experimental group compared with the control group.Rapid elongation in lung bud, advancing in lung development, the lung asflower appearance, Loosely lung mesenchyme ,necrosis in lung tissue ,mucus hypersecretion, elongation in epithelial air ways,epithelial Hyperplasia ,mesenchyme looks as butterfly in appearance in some parts ,thinning of alveolar walls ,thinning of the interstitialmesenchymal lung tissue ,elongation of developing alveolar septa ,free alveolar septa. Alfa - fetoprotein (AFP) levels showed different concentrations value in correlation with congenital malformations .when the (AFP) value was high there were neural tube defects and advancing in the lung development while they were low in normal lung development and in brain hypertrophy.

دراسة مقارنة بين تاثير سترات الكلوميفين وسترات التاموكسيفين على بعض معايير نطف الفئران Comparative Study On The Effects of Clomiphene Citrate And Tamoxiphene Citrate On Some Sperm Parameters In Mice

المستخلص: يعد العقم واحدة من المشاكل الاجتماعية المهمة في معظم انحاء العالم.استنادا الى الاحصائيات الحالية حوالي 15% من المتزوجين يواجهون العقم. يؤدي تقييم السائل المنوي غير الطبيعي للاستروجينات الى تشخيص قلة اعداد النطف ونشاطها وشكلها الطبيعي ومن ناحية اخرى تؤثر | Infertility is one of the most critical social problems in the all of population world. According to the current statistics, about 15% of married couples face with infertility. Assessment of abnormal semen parameters leads to diagnosis of oligoasthenoteratozoospermia, and in others, it leads to isolated abnormalities of sperm concentration, motility, and morphology, due to the lack of differentiable or correctable etiology, Both clomiphene citrate and tamoxiphene citrate, as an anti - estrogen, is the most common prescribed medication for male infertility. In humans, ant estrogens interfere with the normal negative feedback of sex steroids at the hypothalamus and pituitary, thereby increasing endogenous gonadotropin releasing hormone (GnRH) secretion from the hypothalamus and follicle stimulating hormone (FSH) and luteinizing hormone (LH) secretion directly from the pituitary. Objective : The objective of this study was to investigate the effect of clomiphene citrate (CC) and tamoxiphene citrate (TC) administered to male mice on quality of sperm parameters.Materials and Methods : Ninety six male mice were divided into two major groups, and every one of these groups was subdivided into three minor groups involving control and two treated groups. In the CC study, 48 mice were administrated orally 0, 0.0125 mg and 0.025 mg as control (G 1), low dose (G 2) and high dose (G 3) for 42 days. While, in the TC study, 48 mice were administrated orally 0, 0.01 mg and 0.02 mg as control (G 1), low dose (G 2) and high dose (G 3) for 42 days. Then, the male mice were sacrificed, both vas deferens were collected and assessment sperm parameters involving sperm concentration, sperm motility and activity, and normal sperm morphology. Results : The results of present study appeared that the use high dose of CC or TC significantly increment (P<0.05) sperm concentration as compared to control groups. However, use high dose of CC significantly increment (P<0.05) percentages of sperm motility and normal sperm morphology. Meanwhile, the percentage of progressive sperm motility was increased significantly (P< 0.05) when low CC dose administered as compared to control and high CC dose groups. In this study, percentages of sperm motility, progressive sperm motility and normal sperm morphology showed best elevation when used low TC dose as compared to both control and high TC dose groups. High TC dose causes significant increment (P<0.05) in the percentage of sperm agglutination when compared to control and low TC dose groups.Conclusions : Based on the results of this study, it can be concluded that the administration of high dose of either CC or TC increases sperm concentration, while administration of low dose of either CC or TC enhances progressive sperm motility.

التاثيرات المرضية النسجية لعقار ليفيتيراسيتام في التكوين الجنيني لكلى اجنة ومواليد وحوامل الجرذ الابيضAlbino rats (Rattus rattus) Histopathological Effect of Levetiracetam Drug On The Kidney Development In Rats Embryo, Newborns And Pregnant Albino Rat (Rattus Rattus)

المستخلص: الصرع هو حالة مزمنة تتميز بنوبات متكررة دون سابق انذار، سببها خلل في نقل الاشارات الكهربائية داخل الدماغ، وعقار Levetiracetam (LEV) من العقاقير المضادة للصرع، ذو خصائص دوائية ملائمة وتظهر فعاليته في تحسين السيطرة على النوبات، ويكون امتصاصه في البلازما سري | Epilepsy is a condition characterized by recurrent abrupt seizures episodes caused by the defect in the transmission of electrical signals to the brain. LEV is one of antiepileptic drugs which has appropriate pharmacological properties and show its effectiveness in improving the control of the epileptic seizers, its rapid absorbance, and its excretion through the kidneys by glomerular filtration and it is re - absorption into the tubular portion.Kidney arise from intermediate mesoderm and it consists of three execratory organs in all vertebrates : pronephros which is transient and present in all vertebrates, mesonephros which also present in all vertebrates embryos and their activity depends upon the type of embryo, and metanephros which is the functional kidney during life after the embryogenesis in reptiles, birds and mammals. The first signals for kidney initiation in albino rat embryo take place in the 10th days of pregnancy. The current study is designed to demonstrate the effect of LEV (350 mg/kg/day) on the kidney development of Albino rat fetus from the age of 8 - 18 days of pregnancy and its effect on the kidneys of the 3 and 7 days aged newborns. In addition to its effect on pregnant rat kidneys treated with the drug for 17 days. Hundred pregnant Albino rat (Rattus rattus) are enrolled in this study, classified blindly to 50 control and 50 pregnant rats are orally treated with LEV (350 mg/kg/day). The histological results of the current study revealed that there is no effect on embryonic kidney in fetuses aged 9 days of pregnancy, whereas, the pronephros of the fetuses aged 10 days shows death of the cells in comparison to control group. Moreover, the kidney of the 11th aged fetuses showed degeneration of the mesonephric duct represented by decrease cellular mass, death and hypertrophy of some cells comparing to the cells of control group. Concerning the kidney of the 12th aged fetuses and subsequent days, there is degeneration of the epithelial cells of the metanephros duct, their detachment from the basement membrane and their congestion in comparison to the cells of the control group. The kidney of the 13th aged fetuses showed swelling, damage for some of the epithelial cells of the glomerulus and collecting tubules, accumulation and shrinkage of glomerular cells, damage, death, and detachment of some collecting tubules cells demonstrated in the 14th aged fetuses. There enlargement of capsular space in addition to the most previous defects was seen in the 15th aged fetuses in comparison to the control group. Most of the previous defects are seen in the 16th, 17th and 18th age fetuses. Scanning electron microscope revealed nuclear enlargement of the podocytes found in the visceral layer of the renal corpuscle of the 16th aged fetuses (mean diameter 64.6 µm compare to 39.2 µm of the control group). Regarding the kidney of 3rd and 7th aged newborns, the histological defects seen in the latest aged fetuses was also seen and there was statistically significant differences (p?0.05) between the diameters mean of the glomerulus of the 3rd and 7th aged newborn. Whereas, there was no significant difference in the diameter of the kidney tubules of 3rd but there was significant difference of the 7th aged newborn. Regarding the kidney of the 17th day treated pregnant rat, there was enlargement of the capsular space caused by accumulation, and degeneration of glomerular cells characterized by loss of the nucleus, shrinkage of the glomeruli, and atrophy of most of them. Loss of the nucleus and detachment of the cells, and swelling of most of the collecting tubules. There was a statistically significant difference between the diameter of the kidney tubules of the pregnant rat and the control group. In conclusion, LEV had histological effect on the kidney of the 10 - 18 aged fetuses and on 3, 7 days aged newborns in addition to its effect on the kidney of the pregnant female treated with the drug for 17 days.

المستخلص: يعد الاخصاب خارج الجسم الحي (IVF) من احد اهم التقنيات المستخدمة لانتاج اعداد كبيرة من الاجنة لبحوث التطور الاساسيه والبيولوجيا الجزيئية لنضوج البويضات المختبري والاخصاب. يعتمد الاخصاب خارج الجسم الحي وظروف حفظ الجنين المثلى على مكونات الوسط الزرعي كونها ا | In vitro fertilization (IVF) is one of the most important techniques used to produce large numbers of embryos for research into the basic development and molecular biology of in vitro oocytes maturation and fertilization. Optimal IVF and embryo culture conditions depend on the composition of culture media being the most important determinants of success in vitro interaction of the gametes and subsequent embryo development. Adenosine 5 - triphosphate (ATP) is a fundamental factor to maintain life, by providing energy, and controlling the cell function and metabolism. Objectives : The present study aims to investigate the effect of ATP supplied to SMART medium on a rate of fertilization and early embryonic development (ED) in mice as a model for human beings.Materials and Methods : The female mice (90) were superovulated using superovulation program to produce a large number of oocytes. These were divided into three groups, the first group was inseminated with vassal sperm in vitro alone (control); the seconed group (G2) was inseminated with vassal sperm in vitro using SMART medium enriched with low concentration of ATP(1.25mM). The third group (G3) was inseminated with vassal sperm in vitro using SMART medium enriched with high concentration of ATP (2.5mM). Mouse spermatozoa were collected from both vasdeferens. Then sperm parameters were assessed after 30 min. IVF technique was performed for 3 groups, and assessed after 20 - 22h. Then, percentages of early embryonic development stages and abnormal embryos morphology (%) for each embryo stage were assessed.Results : Results of the present study revealed significant increment (P<0.05) in the in - vitro fertilization (%) when using 1.25mM ATP as compared to 2.5 mM ATP and the control group. Significant differences (P<0.05) in the 1 - cell stage were assessed in 2.5mM compared with 1.25mM groups and the control group. Also, Significant differences (P<0.05) in the 2 - cell and 4 - cell stage were assessed in 1.25mM ATP compared with other groups. However, non significant differences in the percentages of abnormal embryos morphology were reported between both treated groups of ATP.Conclusion : From the results of present study it was concluded that the low ATP concentration (1.25mM) enriched to the culture medium improved the percentage of in vitro fertilization and early embryonic development.

نوعية البويضة والتكوين الجنيني بعد الاعطاء الفموي للسبيرماكس لاناث الفئران : موديل تجريبي للبائن Oocyte Quality And Embryonic Development After Oral Administration of Speramax® In Female Mice : Experimental Model For Mammal

المستخلص: Background : Speramax® has been found to play an important role in sperm function characters and males reproductive performance with no studies on its effects on the oocyte maturation and embryonic development in females.Objective : The goal of the thesis is to examine the effect of Speramax ® on oocyte maturation. And to emphasize the effect of Speramax ® on ova quality, embryonic development and newborn. Materials and Methods : Speramax ® treated by oral administration for 1, 2 and 4 weeks. A hundred and twenty six female mice were randomly divided into four groups, the first group was treated without Speramax® with superovulation(SUO) while the second group were treated by Speramax® with SUO and the third group were superovulated only and the fourth group was not treated and spontaneously ovulated (SPO) and considered the control group(thirty two mice). Results : The results indicated that the treatment with Speramax® showed a positive effect on oocytes maturation in vivo. There was a highly significance (p? 0.0001) improvement in number of mature oocytes following treatment with Speramax® in SPO and SUO mice compared with SPO and SUO mice not treated with Speramax®. The embryonic developmental rate after 24 and 48 hours of mating in treated groups with Speramax® was significantly (p? 0.05) higher than those of SPO and SUO mice too.The study showed that the quantity and quality of embryos generated from the treated groups were superior to that of untreated groups.Conclusion : It was concluded that the treatment by Speramax® has a great improvement on oocyte maturation, early embryonic development and embryo grading quality of mice embryos with an increase in the numbers of mice newborn.
