title: Fasting and oxidative activity of hypothalamus, amygdala, frontal cortex and adrenal glands in female rats during different sexual situations--oestrus, dioestrus, ovariectomized--and in male rats.
abstract: We have studied the influence of fasting upon the oxidative metabolism of several cerebral structures (hypothalamus, amygdala and frontal cortex) as well as the adrenal glands in female rats, both during their sexual cycle and ovariectomized, and male rats under a 48h fasting period. Results show significant differences in the oxidative metabolism of the amygdala in both male rats and ovariectomized females on comparing the fasting group with controls; moreover, the frontal cortex of male rats also shows significant differences when comparing both groups. The weight of the adrenal glands is significantly lower in ovariectomized female rats under fasting conditions than in controls. Correlation between the above mentioned cerebral and glandular structures during fasting processes, as well as performance of male and female rats before that situation, is discussed.
