ADRENALECTOMY INDUCED CHANGES IN ESTROUS CYCLE AND TISSUE SOMATIC INDEX IN RATM. VENKATA REDDY, E. MA DHURI AND M. BHASKARAbstract A study was carried out to assess the impact of adrenal hormone in sufficiency on estrous cycle and tissue somatic index in female albino rats. The total time taken for all stages of estrous cycle was higher (93.70 hrs) in adrenalectomized rat when compared to sham operated leading to significant delay (23.72%) in duration of estrous cycle. The whole animal weight of adrenalectamized rat was significantly lowered over sham operated. The tissue somatic index of both uterus and vagina showed no significant change over control however dry matter was reduced in both uterus and vagina leading to elevated water content was absorved on adrenalectomy. It is evidenced that the adrenal insufficiency has induced alterations in estrous cycle and tissue somatic index in female albino rat.
