摘要

实验在３１只兔身上进行。利用自制的刺激电极和微量灌注管对核团进行刺激和微量灌注。观察到一侧孤束核（ＮＴＳ）和脑干网状结构尾端腹外侧区（ｃＶＬＭ）内微量注入ｒ－氨基丁酸（ＧＡＢＡ）后，电刺激ＮＴＳ引起肾交感神经放电反应（ＮＴＳ－ＳＮＤ）的抑制效应明显减弱，可持续１０～１５分钟。说明在兔ＮＴＳ和ｃＶＬＭ中含有对肾交感神经放电和血压调控的ＧＡＢＡ能系统。而ＮＴＳ对交感神经放电抑制和使血压下降至少部分是通过ｃＶＬＭ中的ＧＡＢＡ受体发挥作用的。

Abstract

xperiments were performed on 31 rabbits. The technique provides a highly localized drug adminstrationand electrical stimulation on NTS. Ipsilateral microinjection of r-amino butyric acid(GABA) into NTS orcVLM could diminish the SND inhibitory and depressor responses elicited by electrical stimulation of NTS. These responses usually lasted 10-15 min

The results of the present study indicate that there is GABAergicsystem responsible for SND and arterial pressure control in the NTS and cVLM of the rabbit.The sympatho- inhibitory responses evoked from NTS are mediated

at least in part by GABA receptors in the cVLM.
