人工虫草提取物抗心律失常作用的研究

Antagonistic Effects ofExtracts from Cultural Mycelium of Cordyceps sinensis on Arrhythmia

摘要: 目的：利用乌头碱、氯化钡所致大鼠心律失常模型比较人工虫草提取物对实验性心律失常的保护作用。方法：采用乌头碱，氯化钡分别制备心律失常实验模型。观察虫草提取物的保护作用。结果：人工虫草菌丝体石油醚提取物抗心律失常作用较强，可明显对抗乌头碱所致大鼠的心律失常，延长心律失常的诱发时间，降低心律失常持续时间及严重程度；对氯化钡所致心律失常也有一定的对抗作用，可降低心律失常严重程度。结论：人工虫草菌丝体石油醚提取物为抗心律失常的有效部位。
