从人参不同部位:人参茎叶、芦头、果及主根所提取的总皂甙,以相同剂量给大鼠灌胃(ig)7天,用异丙基肾上腺素(ISO)造成心肌坏死,观察心电图、血清酶学(CPK、LDH及r-GT)变化以及病理变化和糖原含量。结果表明:各种部位的皂甙均能保护心肌,使之病损减轻,尤以人参果皂甙作用为佳。以β受体阻断剂心得安为阳性对照,人参不同部位皂甙与心得安作用获相似结果。 From the different parts of ginseng: total saponins extracted from ginseng stems and leaves, reed heads, fruits, and main roots, the rats were fed with the same dose for 7 days (ig) for 7 days, isoproterenol (ISO) was used to cause myocardial necrosis, and the electrocardiogram was observed. Changes in serum enzymology (CPK, LDH, and r-GT) as well as pathological changes and glycogen content. The results showed that all kinds of saponins could protect the myocardium and reduce the lesions, especially ginsenosides. The beta-blocker propranolol was used as a positive control, and saponins at different sites of ginseng had similar results to propranolol.
