摘要

黄鼠下丘脑、垂体 中的#beta#-内啡肽在入眠过程中增多, 在深眠状态下的含量又 高于入眠期; 海马、血浆中的#beta#-内啡肽含量变动趋势正好相反, 在入眠期与深眠 期低于常温水平; 桥延脑中含量在冬眠阵过程中变化不大。甲啡肽含量在入眠期升高, 在深眠期重新下降, 不同脑区趋势相同但程度各异, 以海马中的变动最为明显。

Abstract

The #beta#-EP content in hypothalamus and pituitary during the entrance phase were increased and further deepened during deep hibernation, whereas in hippocampus and plasma the tendency of the changes of #beta#-EP content took place in an opposite direction, i.e.being lowered down from the euthermia level upon entering the entrance and deep hibernation phase. The content on pons and medulla showed little change through the bout. The contents of MEK were increased during entrance and lowered when entering into deep hibernation to different extent in different brain areas, being most significant change has taken place in hippocampus.
