Abstract
The influence of alloxan diabetes on reproductive function and the estradiol-stimulated increase in uterine peroxidase was investigated. Alloxan monohydrate in a dose of 75 mg/kg body weight effectively produced permanent diabetes. In adult rats, 20 days of diabetes resulted in cessation of the estrous cycle and a significant reduction in the gain of body weight, the weights of anterior pituitary gland, ovary, uterus, the level of serum progesterone and the activity of the estradiol-stimulated uterine peroxidase (P < 0.05). After 10 days of insulin treatment, the ovarian weight, the estrous cycle and the level of ovarian hormones were restored to normal whereas the uterine weight and the estradiol-stimulated uterine peroxidase activity were only partially recovered. Persistent depression of the uterine response in the insulin-treated diabetic rats to both endogenous and exogenous ovarian hormone stimulation suggests that the uterus was directly affected by diabetes. The direct effect of diabetes upon the uterus was further demonstrated in the ovariectomized immature rat in which diabetes depressed the stimulatory action of estradiol on both uterine weight and uterine peroxidase activity. © 1984.
