The study designed to evaluate influence of kisspeptin on polycystic ovary syndrome in female rats, First experiment (Induction of polycystic ovary): thirtieth virgin female rats divided randomly into two groups first group via used ten rats serves as control group . While the second group twenty female rat (PCOS-induce group) were orally administered with letrozole at a dose of 1 mg/kg/21 days. The Second Experiment Effect of treatments with kisspeptin on PCOS : Animals were divided as follows: first group (negative control) .Second group (Positive control) .While animals in third and fourth groups (PCOS+Kisspeptin): five animal in each group PCOS-induced rats administrated of 20 and 40 nmol/rat S/C 21 days Kisspeptin daily respectively .The result show in first experiment a significant increase in serum activity of LH, FSH, estrogen and testosterone and significant decrease progesteron concentration in serum of female rats treated with letrozole. While in the second experiment there was significant decrease in FSH in the C+ compared with C and PCOS treated group. A significant increase in the LH in C+ compared with C and treated group 20 and 40 nmol/rat Kisspeptin . Also the results showed that there was a significant decrease in serum estrogen concentration was observed in PCOS nontreated group compared with control. On other hand a significant increase in serum estrogen in T1(20 nmol/kg B.W) compared with T2(40 nmol/kg B.W). The results of the histopathological study of ovary after treatment PCOS with kisspeptin 20 nmol/kg show partial return of follicular cyst to normal ovarian tissue, but the treated with 40 nmol/kg show semicomplete treated and return follicular cyst to normal ovarian tissue. On conclusions, the present study confirmed that PCOS affect the female reproductive hormonal balance and kisspeptin 40 nmol/rat daily S/C injection show effect in normal restoring of female reproductive hormonal and histological balance of PCOS rats.

This study was designed to induction of testicular degeneration syndrome (TDS) in male rats by cadmium chloride and identified the best concentration of induction for this syndrome. The effective dose of cadmium chloride (CdCl₂)  was determined by used fifteen males rats and where divided into three equal groups treated with CdCl₂ in a concentration (1, 2 and 3)mg/kg B.W. I.P. one /week for two weeks. Later the experimental animals was scarified and testis was took for measuring the antioxidant parameters via evaluated of glutathione GSH,  malondialdehyde MDA, catalse, albumin, fructose concentrations and aminotransferase activity (ALT and AST). According to this result the lowest observed adverse effective dose (LOAEL) of cadmium chloride that induced testicular degeneration in male rats was found to be 1mg/kg B.W. I.p. one /week for two weeks.

The study was designed to evaluated exocrine pancreatic enzyme replacement therapy in hyperglycemic male rats induced by alloxan. A total of forty five adult male rats were use in this study, hyperglycemia was induce in thirty rats by single intraperitoneal (i.p) injection of Alloxan 100mg/kg/B.W. and the experimental (45) distributed into three groups: the first group (15 animals) administered distilled water orally service as control group. The second group hyperglycemic groups (15 animals) was treated with exocrine pancreatic enzyme(EPE).The third group hyperglycemic group non treated with exocrine pancreatic enzyme(NEPE). Blood samples were take in days 20,40,60 of experiment for measurement the following parameters: Serum some biochemical parameters, tissue pancreatic activity. The results showed that tissue orally gavages exocrine pancreatic enzyme(EPE) caused a significant elevation in tissue amylase activity in all treated group as compared to the control group. and significant increase in tissue amylase and decrease lipase and protease in concentration in EPE treated group as compared to the non-treated (NEPE) group. Also serum insulin concentration significant decrease and glucose showed a significant increase in EPE and NEPE groups when compared with the control group in after 20,40 and 60 day of experiment. The serum albumin showed significant decrease in all EPE groups when contrasted with the control group. And also The results illustrated that significant decrease in albumin concentration in all NEPE as compared to the control group. The Serum protein concentration was significant decrease in EPE and NEPE groups as compared to the control group in all experimental day. The results showed significant increase in serum cholesterol and triglyceride in EPE as compared to the NEPE . The results showed that PEP rats caused a significant decrease in serum high density lipoprotein (HDL)concentration as compared to the control group and significant decrease in HDL concentration in NEPE as compared to the control group. results showed that doses rats caused a significant(P

The fermentable fiber, Vitacel R200 is industrial compound cellulose exerting many beneficial health effects at the hosts. In this study, rainbow trout (Oncorhynchus mykiss) fingerling (120 ± 4.5 grams) were fed dietary 1% (10 g/kg feed) Vitacel R200 for 7 weeks, then challenged with Aeromonas hydrophila. Two weeks after the challenge, hemato-biochemical and immune parameters in the challenged fish were studied. The lysozyme and complement activity, as well as, white blood cells (WBCs), hemoglobin (Hb%), percentage of neutrophil and eosinophil in the fish fed Vitacel were significantly increased compared with the control group. Furthermore, the serum total protein, albumin, Na+, K+, P, and Ca++ concentrations in the fish fed diet containing 1% Vitacel were significantly increased, while alanine aminotransferase (ALT), alkaline phosphatase (ALP), and aspartate aminotransferase (AST), as well as, cortisol, cholesterol, and glucose concentration were significantly decreased in comparison to the control group. These results concluded that dietary Vitacel could improve the hemato-biochemical and immune parameters, as well as, the stress response in O. mykiss infected with A. hydrophila.
