Effects of chlorpromazine and estradiol benzoate on prolactin secretion in gonadectomized male and female rats.
The effects of chlorpromazine (CPZ) and estradiol benzoate (EB) on serum prolactin (PRL) levels were studied in gonadectomized male and female rats. In both sexes CPZ (25 mg/kg body weight) produced an elevation of PRL when measured 2 hr after the injection, but the elevated levels were higher in ovariectomized rats than in orchidectomized rats. These results reconfirm a sexual difference in th...

15 صفحه اولCholesterol metabolism in gonadectomized rats.
In studies in which tissue concentrations of cholesterol and total lipids were determined in male and female rats fed a control diet containing fat, the effects of gonadeetomy were much smaller than in animals fed a fat-free diet in which gonadeetomy tended to reverse the sex differences observed in these lipid values. Other phases of lipid metabolism were shown to be sex-linked as well. Gonade...
متن کاملGentamicin Induced Nephrotoxicity: The Role of Sex Hormones in Gonadectomized Male and Female Rats
Background. Gentamicin (GM) induced nephrotoxicity may be sex hormones related. The effects of sex hormones on GM induced nephrotoxicity in gonadectomized rats were investigated. Methods. Ovariectomized rats received 0.25, 0.5, or 1 mg/kg/week of estradiol (ES) alone or accompanied with 10 mg/kg/week of progesterone (Pro) for two weeks followed by GM (100 mg/kg/day) for 9 days. Castrated rats w...
متن کاملEstradiol and isotype-selective estrogen receptor agonists modulate the mesocortical dopaminergic system in gonadectomized female rats.
The mesocortical dopaminergic pathway projecting from the ventral tegmental area (VTA) to the prefrontal cortex (PFC) contributes to the processing of reward signals. This pathway is regulated by gonadal steroids including estradiol. To address the putative role of estradiol and isotype-selective estrogen receptor (ER) agonists in the regulation of the rodent mesocortical system, we combined fM...
