摘要: 绞股蓝总皂甙能明显延长离休豚鼠心房功能性不应期(FRP).其值由给药前的201±12ms延长至给药后的225±9ms。绞股蓝总皂甙还能浓度依赖性地降低离体豚鼠右心房的自律性.绞股蓝总皂甙对离体豚鼠心房肌的收缩性无明显影响.Abstract: The function refractory period (FRP) of isolated left atria of Gunla Pig ovas Prolonged by gypenosides 2 10-3mg/ml from 201+12 ms to 225 +9 ms. Gypenosides also descreasedthe automatic rhythms of right atria.The contractility of Gunia pig atria was not a
