摘要
目的 研究复方丹参、生脉注射液对中枢神经—肌接头和肌肉疲劳的影响。方法 记录蟾蜍坐骨神经干动作电位和腓肠肌收缩曲线 ,测定中枢、神经—肌接头、肌肉出现疲劳的时间。结果 同对照组比较 ,丹参组和生脉组中枢、神经—肌接头、肌肉出现疲劳的时间都明显延长。差异具有显著性 (P <0 0 1)。结论 复方丹参、生脉注射液具有抗中枢、神经—肌接头和肌疲劳的作用。
Objective To study the effects of injection Salvia milterrhizae and Shengmai on fatigue in center, neuromuscular junction excitation transmission and muscular contraction Methods To check appearing time for the fatigue of center, neuromuscular junction and muscle, by measuring the action electric potential of the sciatic nerve trunk and the contraction tension of gastrocnemius muscle Results Salvia milterrhizae and Shengmai group elongated the appearing time for fatigue of center, neuromuscular junction and muscle Compared with control group. there were significantly differences ( P <0 01) Conclusion The results suggested that Salvia milterrhizae and Shengmai had the effects of preventing fatigue in center, neuromuscular junction, and muscle
