羌活提取物(ENR)对乌头碱致大鼠、哇巴因致豚鼠心律失常及麻醉大鼠缺血-再灌注心律失常有保护作用。口服羌活提取物4000mg/kg能延迟乌头碱致大鼠心律失常的出现时间,提高哇巴因致豚鼠室颤和心搏停止的用量,降低大鼠缺血-再灌注诱发的室早、室速和室颤的发生率。
Notopterygium extract (ENR) has protective effects on arrhythmic rats induced by aconitine, ouabain induced guinea pig arrhythmias and ischemia-reperfusion arrhythmias in anesthetized rats. Oral Notopterygii extract 4000mg / kg can delay emergence of aconitine induced arrhythmia in rats, increased ouabain induced guinea pig ventricular fibrillation and asystole dosage, reduce ischemia-reperfusion-induced ventricular premature ventricular Speed and the incidence of ventricular fibrillation.
