摘要

本实验在30只氯醛糖-乌拉坦混合液麻醉的Wistar系大白鼠上，观察了夹闭大鼠双侧颈总动脉所致脑缺血及脑缺血后电针“合谷”穴对大脑皮层体感诱发电位（SEP）的影响。结果表明：脑缺血后SEP的P1波及N1波波幅明显减小，峰潜伏期明显延长，但以波幅减小的变化更为明显；电针“合谷”穴可使SEP的P1、N1波波幅在脑缺血后减小的基础上明显升回。提示SEP可作为反映脑缺血的客观指标，电针“合谷”穴可起到明显改善脑缺血的作用。

Abstract

The dynamic changes of cortical somatosensory evokded potential during occluding bilateral common carotid arteries and electroacupuncturing "Hegu"point were recorded and observed IN 30 wistar rats anesthetized with chloralose and urethane

The main results were as follows: After brain ischemia

P. N. amplitudes of SEP were significantly depressed

and the spike latency of SEP is obviously increased. The decreased amplitude of SEP during brain ischemia could be obviously increased by electroacupuncturing "Hegu" point. It is suggested that SEP may be an indicator to show brain ischemia

and acupuncturing "Hegu"point could improve brain ischemia.
