观察复方毛冬青抗氯仿、Cacl_2、Bacl_2所致的心律失常作用。结果表明该药对氯仿、Cacl_2诱发小鼠的心律失常具有对抗作用,降低心室颤动发生率及死亡率,提高Bacl_2诱发心律失常的阈剂量,并能推迟心律失常的出现时间。通过离体的蟾蜍心脏,观察到复方毛冬青有降低心肌收缩幅度及减慢心率的作用。 Observed the effect of compound Mao Dongqing on arrhythmia induced by anti-chloroform, Cacl_2 and Bacl_2. The results showed that the drug had antagonistic effects on arrhythmia induced by chloroform and Cacl 2 in mice, reduced the incidence of ventricular fibrillation and mortality, increased the threshold dose of Bacl 2 -induced arrhythmia, and delayed the occurrence of arrhythmia. Through the isolated sacral heart, it was observed that compound hollycium has the effect of reducing myocardial contraction and heart rate.
