Résumé

Wistar strain albino rats were hysterectomized and the estrous cycle was compared with sham operated controls. Duration of estrous cycle in hysterectomized rats increased markedly with significant delay in the luteal phase and this was correlated to the inhibited follicular development of ovary. When these rats were treated with PGF2 alpha and PMSG and subjected to physical exercises, the estrous cycle was synchronised and the ovaries of such animals had active follicular development. Thus the deranged operation of sexual cycle in hysterectomized rats was regulated through physical exercises.

Résumé

Wistar strain albino rats were subjected to bilateral hysterectomy surgically and the ovarian carbohydrate metabolism of these animals was compared with sham operated controls. The ovarian glycogen content of hysterectomized animals was elevated with inhibition of glycogenolysis, hexose mono and diphosphate pathways and oxidative metabolism. Administration of PGF2 alpha to hysterectomized animals led to activation of ovarian glycogenolysis and other pathways of carbohydrate metabolism of hysterectomized animals was restored towards normal level after PGF2 alpha substitution.

Résumé

ATPase activity of uterus and ovary was markedly elevated in presence of gossypol and decreased in presence of lactic acid indicating activation and inhibition of energy metabolism by gossypol and lactic acid respectively. The elevated levels of glycogen in uterus indicate inhibition of glycogenolysis as supported by phosphorylase activity. Whereas in ovary the glycogen depletion indicates activation of glycogenolysis supported by phosphorylase activity. The activity levels of aldolase and G-6-PDH decreased in the uterus in presence of gossypol and increased in presence of lactic acid. The same were elevated in ovary indicating the activation of hexose mono and diphosphate pathways. Lactic acid accumulated in presence of both gossypol and lactic acid with a depletion in level of pyruvic acid in both the tissues. This situation in the uterus indicates the condition of anti-implantation in presence of both gossypol and lactic acid. The NAD-LDH activity was inhibited in presence of gossypol and activated in presence of lactic acid in both tissues.
