| 摘 要： | 目的 :研究小分子多肽类物质心肌肽素对大鼠心脏缺血 再灌注损伤的预防作用。方法 :在大鼠冠脉结扎致心肌缺血 再灌注损伤模型上 ,观察心肌肽素预防性给药对缺血大鼠血浆中肌酸磷酸激酶 (CPK)、乳酸脱氢酶 (LDH)活性及脂质过氧化物终产物 (MDA)含量的影响。结果 :心肌肽素预防性给药能明显降低血浆CPK ,LDH的活性与MDA含量 ,其作用具有明显的量效关系。结论 :心肌肽素对心脏缺血 再灌注损伤有预防作用 ,这可能与其减少心肌酶的释放及抗心肌脂质过氧化有关。

| Abstract: | Objective:To investigate the preventive effect of cardiomyopeptidin of small molecular weight polypeptide on rat hearts injured by ischemia reperfusion.Methods:In a rat model injured by ischemia reperfusion in the heart,observation was made on the influence of cardiomyopeptidin on the activities of creatine kinase(CK)and lactate dehydrogenase(LDH),as well as on the content of MDA in plasma after the preventive drug was used.Results:Cardiomyopeptidin could obviously prevent the injury caused by ischemia reperfusion,reduce the activities of CK and LDH and the content of MDA in a dose dependentmanner.Conclusion:Cardiomyopeptidinhas a preventive effect on myocardium injured by ischemia reperfusion and this may be related to its reducing the release of myocardial enzyme and anti lipoperoxidation. |
