束缚应激对大鼠胃肠电活动的影响及机制探讨

Mechanism and Effect of Restraint Stress on Gastrointestinal Myoelectric Activity in Rats

我们观察了束缚应激对大鼠胃肠电活动的影响。结果发现：束缚应激时，胃电活动增强，小肠电活动减弱，小肠ＩＤＭＥＣ周期性活动中断，代之以散在的不规律的峰电活动。迷走神经和交感一肾上腺素能神经均不同程度地参与了胃肠电活动的应激性变化，但胃以迷走神经活动为主，小肠以交感神经活动为主。

bserved the effects of gastrointestinal myoelectric activity by restraint in rats,we found: l )By restr-aint stress,the myoelectric activity of antrum was enhanced,hut of the small bowel was attenuated and theIDMEC cycle of the small bowel was interruped, insteadly the irregular electric activity occurred,2)Thechanges of restraint stress on gastrointestinal myoelectric activity in rats were involved in the vagus andsympathetico一adrenal nerve.
