摘要: 目的: 观察冠通活瘀胶囊对小鼠注射异丙肾上腺素(ISO)后耐缺氧存活时间和注射垂体后叶素(Pit)所致的心肌缺血的影响。方法: 采用腹腔注射ISO后观察小鼠耐缺氧存活时间和尾静脉注射Pit致大鼠急性心肌缺血模型,观察各给药组在腹腔注射ISO后耐缺氧存活时间和注射Pit后不同时间点Ⅱ导心电图T波变化百分率,心率变化及对血清肌酸激酶(CK)、乳酸脱氢酶(LDH)和谷草转氨酶(AST)的影响。结果: 冠通活瘀胶囊低、中剂量组与模型组比较,均能明显延长小鼠耐缺氧存活时间和降低心肌缺血大鼠心电图T波峰值变化百分率(P<0.05);与注射Pit前比较,能对抗Pit致心率减慢的损伤,并能显著降低血清中CK、LDH和AST的含量。结论: 冠通活瘀胶囊具有降低小鼠心肌耗氧量和抗Pit引起的大鼠急性心肌缺血作用。

Abstract: AIM: To investigate the effect of Guanxinhuoyu Capsule against hypoxia after injection of isoproterenol and in rats with acute myocardial ischemia induced by pituitary.METHODS: The anti-hypoxia model was established by injection of isoproterenol and the acute myocardium ischemia rat model was established by caudal venous injection of pituitrin.The survival time and the changes of the T wave in lead II ECG and heart rate were observed.RESULTS: Guanxinhuoyu Capsule for low and medium dose groups compare with model group, could significantly prolong the survival time by isoproterenol in mice and significantly lower the percentage change of T wave inhibit slowed heart rate induced by pituitrin in rats, and notably decrease the levels of CK, LDH and AST.CONCLUSION: Guanxinhuoyu Capsule reduces myocardial-oxygen consumption and anti-myocardial ischemia effect in rats with acute myocardium ischemia induced by pituitary.
