摘要
目的:观察冠心平对异丙肾上腺素(ISO)致大鼠心肌缺血的影响。方法:采取大鼠scISO(30mg·kg-1)致急性心肌缺血模型,观察冠心平对大鼠血清乳酸脱氢酶(LDH)、肌酸磷酸激酶(CK)、丙二醛(MDA)、超氧化物歧化酶(SOD)活性的影响;观察注射ISO后不同时间J点下降情况,心肌病理损伤程度的影响;结果:冠心平各剂量组均可不同程度降低LDH,CK活力降低血清MDA水平,升高SOD水平(P<0.01,P<0.05);明显抑制ISO引起的大鼠心电图J点下降(P<0.05,P<0.01);心肌病理损伤程度明显减轻。结论:冠心平对ISO致大鼠心肌缺血模型具有明显保护作用。
Objective:To observe the effect of Guanxinping on myocardial ischemic injury induced by isoprenaline in rats. Method:Rat myocardial ischemia was induced by subcutaneous injection of isoprenaline(30 mg·kg^ -1 ). The effect of Guanxinping on the lactate dehydrogenase ( LDH),serum creatine kinase ( CK),malondial dehyde (MDA)and superoxide dismutase (SOD)was observed. The descent of J point at different time after injection of isoprenaline was examined,and pathological investigation of myocardial injury in rats was carried out. Result:Guanxinping could obviously inhibit the activities of serum CK,LDH,and MDA ,enhance serum SOD activity(P 〈0. 01,P〈 0. 05). Guanxinping could inhibit descent of J point in rat myocardial ischemia induced by isoprenaline( P〈 0. 05,P〈 0. 01 ),and significantly reduce the extent of myocardial pathological damage. Conclusion:Guanxinping can obviously ameliorate myocardial ischemic injury induced by isoprenaline in rat.
