摘要

西洋参茎叶皂甙(100,300,500μg/ml)可剂量依赖性使培养大鼠心肌细胞动作电位的波幅、波宽、阈电住、最大舒张电位,最大除极速度及复极50%水平的动作电位波宽一致性减小。与二氯化锰(0.1μg/ml)和异搏定(1μmol/L)比较可产生相似作用。钙离子(200mmol/l)可翻转西洋参茎叶皂甙(300μg/ml)的作用。初步观察表明,该药可能具有钙通道阻断作用。

Abstract

In this experiment,PQS(100,300,500μg/ml)decreased the amplitude of actionpotential, overshooting, threshold, maximum diastolic potenlic,maximum rate of depolarizationand action potential duration at 50%level repolarization in cultivated rat cardiac cells. The effectsof PQS(300~500μg/ml) were similar to those of MnCl2(0.1μg/ml) and verapamil(1.0μmol/L)。The Ca ̄(2+)(200mmol/L)could reverse the effect of PQS(300μg/ml)on inhibiting electricalparameter of action potential of rat cells. The results indicated that PQS may affect calcium channel block.
