The dynamic changes of cortical somatosensory evoked 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.
在30只用氯醛糖和乌拉坦麻醉的Wistar大鼠中，记录并观察了双侧颈总动脉闭塞和电针“合谷”穴时皮质体感诱发电位的动态变化。主要结果如下：脑缺血后，SEP的P.N.波幅明显降低，SEP的峰潜伏期明显延长。电针“合谷”穴可明显增加脑缺血时SEP降低的波幅。提示SEP可能是显示脑缺血的指标，针刺“合谷”穴可改善脑缺血。
