Abstract

To investigate the effect of cardiomyopeptidin for injection on energy metabolism in isolated hearts of young rats after ischemia-reperfusion injury. Fifty young healthy SD rats(aged 20 +/- 3 days and weighing 50-70 g) were randomly divided into 5 groups: a normal control group (NC group, n = 10 ): the isolated hearts were stable for 20 min, and then 150 min continuous perfusion; a normal + cardiomyopeptidin group (NCMP group, n = 10): the same as the normal control group, but K-H buffer solution was added with 50 mg/L cardiomyopeptidin, and 3 ischemia-reperfusion injury model groups, including a model control group (n = 10): the isolated rat hearts were perfused with K-H buffer and then arrested with cardioplegic solution; a CMP1 group (n = 10): the ST.Thomas'II cardioplegic solution was added with 100 mg/L cardiomyopeptidin; CMP2 group (n=10): K-H buffer and ST.Thomas'II cardioplegic solution was added with 50 mg/L and 100 mg/L cardiomyopeptidin respectively. The cardiac functional indexes were monitored, including heart rate, myocardial contractility and diastolic function, peak systolic and diastole myocardial velocities and coronary flow. In the 3 ischemia-reperfusion injury model groups, myocardial ultrastructure was obse...Continue Reading
