| 摘 要： | 应用一种饥饿与复食相交替的间歇饥饿法,观察慢性饥饿对垂体性腺轴的影响。在间歇饥饿期间,大鼠的动情周期几乎完全停止,切除一侧卵巢也不能引起对侧卵巢的代偿性肥大,表明在间歇饥饿时性激素对垂体促性腺激素分泌的负反馈作用增强,而正反馈作用减弱或消失。

| Abstract: | The effect of chronic starvation on pituitary-gonadal axis was observedby a new procedure of intermittent starvation, i. e. alternative starvationand refeedings. During intermittent starvation the estrous cycle was depressedalmost completely and extirpation of one ovary could not induce hypertrophyof the other. Thus enhanced negative and decreased positive feedback actionsof sex steroids upon gonadotrophin secre tion were indicated duringintermittent starvation. |
