The results of present study showed that the liver of the Collard Dove and Ruddy Shelduck was covered by a thick connective tissue capsule, formed of collagen fibers and some reticular fibers. Hepatocytes were arranged as irregular anastomosing cords of two cells. The cords were separated from each other's by blood sinusoids. The hepatocytes were large polygonal cells with large rounded nuclei. The portal triads containing branches of hepatic artery, portal vein, bile duct and lymph vessels.
L-Arginine has hypoglycemic and antioxidant effect in Alloxan diabetic animals and reduce effect of diabetes complication on spermatogenesis. antioxidant have essential effect on spermatogenesis, L-Arginine has antioxidant and hypoglycemic effect. Enhanced oxidative stress and changes in antioxidant capacity are considered to play an important role in the pathogenesis of chronic diabetes mellitus. Sixteen mature male rats aged 10 weeks ,were randomly divided into four equal groups as follows 1 st diabetic group (DG) that received 150 mg/kg (IP) Alloxan single dose ;2 nd group diabetic group treated with (L-Arginine-Hcl)(DAG) received 150mg/kg (IP) Alloxan as single dose plus L-Arginine-Hcl 200mg/kg(IP)-per day, 3 ed group treated with(L-Arginine-Hcl)(AG) received 200mg/kg-(IP) perday ,and 4 th were control group(CG) non treated .In 60 day the blood samples collected from heart to make serological parameters (glucose level) and testes removed to observe their Histopathological. Serum Glucose concentration showed a significant increase (p<0.05) in diabetic group (DG) compared with other groups while diabetic treatment group that has received L-Arginine 200 mg/kg(IP) (DAG) showed a significant (p<0.05) decrease compared with (DG).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
