Studies on effect of chronic intermittent starvation on neuroendocrinous function in rats

This paper studies the dynamic changes of neuroendcrinous function during chronic intermittent starvation in rats and compares it with the result of acute starvation. The data shows that chronic intermittent starvation causes an elevation in pituitary weight per 100g body weight and no significant changes are found in accessory sex organs ,the changes can return to normal rapidly after refeeding. In chronic intermittent starvation, pituitary PRL and blood PRL show no significant changes, induced PRL serection is attenuated. A significant difference is revealed between chronic starvation and acute starvation. Although the body weight drops in the same degree during the above two kinds of starvation, various ways and periods of starvation can cause different changes in neuroendocrinous function.
