摘要

实验在２８只麻醉兔身上进行。用方波串电刺激一侧颈迷走伸经中枢端（ＣＶＮ）常引起肾交感神经反时性放电（ＲＳＮＤ）以抑制为主的反应（占３０８／３６５实验）．平均抑制时间为３．６１±０．１８秒。这种ＣＶＮ－ＲＳＮＤ反应是随着中枢神经系统状态的变化而变化的，表现为ＲＳＮＤ的抑制时间延长或缩短。一般来说，引起交感神经背景活动增加时，迷走传入对交感神经传出活动的抑制就减弱。这种交感与副交感神经间的关系在外界环境适应中发挥了重要作用。

Abstract

his study investigated the effect of electrical stimulation of the central end of cervical vagal nerve(CVN)on renal sympathetic nerve discharge (RSND)in 28 anesthetized rabbits. One of the common respons-es was an immediate increase of sympathetic efferent acthity and then followed by its complete complete cessation(308/365 exp).The average inhibitory time is 3.61±0.18s.The inhibition time of the CVN-RSND response could prolonged or shortened while the function of theCentral Nerve System were changed.Changes in the basal sympathetic tonic activity seem to contribute muchto the response when a vagal stimuls was applied

Whenever the based sympathetic tonic activity increased.the effect of CVN-RSND diminished.This mechannism play:an improtant role in the adaptation to the envi-ronmental requirments.
