Abstract

Rats were kept for one and six hours in a thermal chamber at a temperature of -4 degrees C under conditions of free choice between 5% ethanol and water. Study of the morphological picture of the supraoptic and paraventricular nuclei of the hypothalamus and neurohypophysis of rats that preferred alcohol or rejected it has shown an inverse relationship between marked initial preference of alcohol and resistance of the hypothalamohypophyseal neurosecretory system of the animals to hypothermal exposure that exhausts the neurosecretory function.

摘要

将大鼠置于温度为-4摄氏度的热室中1小时和6小时,让其在5%乙醇和水之间自由选择。对偏好酒精或拒绝酒精的大鼠下丘脑视上核和室旁核以及神经垂体的形态学图像研究表明,动物对酒精的明显初始偏好与下丘脑-垂体神经分泌系统对耗尽神经分泌功能的低温暴露的抵抗力之间存在反比关系。
