Effect of lead on male gonadal activity in albino rats.
Lead poisoning often prevails in children and industrial workers. The present study was undertaken to evaluate the effects of lead acetate on steroidogenic functions of testis, serum levels of gonadotrophins and testosterone in albino rats. Testicular steroidogenic activity was evaluated by measuring the activities of two steroidogenic key enzymes, Delta5-3beta hydroxysteroid dehydrogenase (Del...
متن کاملProtection of adrenocortical activity by dietary casein in ether anaesthetized rats.
Adrenal delta5-3beta-hydroxysteroid dehydrogenase (delta5-3beta-HSD) activity and serum corticosterone level were significantly higher in rats fed with 5% casein or 4% albumin diets after 1 hr of ether anaesthetic stress as compared to the controls, 5% casein and 20% casein (equivalent to 4% albumin) respectively. Ether anaesthesia to 20% casein fed rats caused no change in adrenal delta5-3beta...
متن کاملEffect of casein diet on gonadotropin releasing hormone antagonist induced changes in adrenal gonadal functions in male rats.
Adult male rats received daily injections (sc) of gonadotropin releasing hormone antagonist (0.2 mg/kg(-1) x day(-1)) for 21 days when they were sacrificed on day 22, adrenal weight, adrenal A5-3beta (delta 5-3beta) hydroxysteroid dehydrogenase (Delta5-3beta-HSD) activity and serum level of corticosterone were increased significantly while testicular 17beta (17beta) hydroxysteroid dehydrogenase...
متن کاملThe engineered, cytosolic form of human type I 3beta-hydroxysteroid dehydrogenase/isomerase: purification, characterization and crystallization.
Human type I 3beta-hydroxysteroid dehydrogenase/isomerase (3beta-HSD/isomerase) is an integral membrane protein of human placental trophoblast and of insect Sf9 cells transfected with recombinant baculovirus containing the cDNA encoding the enzyme. Purified native or wild-type enzyme remains in solution only in the presence of detergent that may prevent crystallization. The membrane-spanning do...
متن کاملProtection of adrenal and male gonadal functions by androgen in lead-treated rats.
The potential health hazard of the large amounts of Lead that occurs in canned baby food, domestic water from lead-lined tanks and, in printing and petroleum industries. Lead acetate administration at a does of 8 mg/kg body weight for 21 days resulted a significant increase in adrenal steroidogenic enzyme (Delta5-3beta- HSD) and serum levels of corticosterone, while serum levels of testosterone...
