摘要: 目的: 观察淫羊藿总黄酮静脉注射和胃肠道给药途径对实验性心肌缺血的影响。方法: 采用异丙肾上腺素(20 mg/kg)皮下注射诱导产生小鼠急性心肌缺血模型, 观察淫羊藿总黄酮注射液(i.v.,PSTFE)和淫羊藿总黄酮提取物(i.g., TFE)对急性心肌缺血小鼠耐缺氧能力的影响;结扎麻醉犬冠状动脉建立急性心肌缺血模型, 观察静脉滴注(iv gtt)PSTFE 和十二指肠给药(i.d.)TFE 后心外膜电图,测定血清中肌酸激酶(CK)、乳酸(LD)、超氧化物歧化酶(SOD)和丙二醛(MDA)的含量及心肌梗死范围。结果: PSTFE(i.v.)和TFE(i.g.)均能显著延长急性心肌缺血小鼠的存活时间(P<0.01);PSTFE iv gtt 和TFE 十二指肠给药(i.d.)后能明显降低犬心肌缺血后心外膜电图的△N-ST 和△∑-ST 值, 缩小心肌梗死范围, 降低血清中CK、LD 和MDA 值, 增加SOD 的活性(P<0.01 或P<0.05)。结论: 淫羊藿总黄酮静脉注射和胃肠道给药途径对实验性心肌缺血均有明显的保护作用。

Abstract: AIM: To observe the effects of total flavones of epimedium on experimental myocardial ischemia through intravenous injection and gastroenter-administration pathway. METHODS: Acute myocardial ischemia model of mice was induced by subcutaneous injection (s.c.)of isoproterenol (20 mg/kg).The effects of the injection of total flavones of epimedium(PSTFE, i.v.) and total flavones of epimedium(TFE, i.g.)on the survival time of mice were observed.Acute myocardial ischemia model was induced by ligating coronary artery in anaesthetized dogs. Then epicardium electrocardiogram (EECG)was measured, and creatine kinase (CK), lactic acid (LD), superoxide dismutase (SOD)and malonaldehyde (MDA)in the serum, cardiac infarction area were determined respectively. RESULTS: PSTFE (i.v.)and TFE (i.g.)could both significantly increase the survival time of acute myocardial ischemia mice(P<0.01).PSTFE (iv gtt)and TFE (i.d.)could obviously reduce the value of △N-ST and △∑-ST, decrease the infarction area, notably decrease the levels of CK, LD and MDA in the serum, and distinctly increase the level of SOD(P<0.05). CONCLUSION: Total flavones of epimedium through intravenous injection and gastroenteradministration pathway have significantly protective effects on experimental myocardial ischemia.

Key words: total flavones of epimedium, myocardial ischemia, isoproterenol, coronary artery ligation
