- Abstract: Objective To explore the protective effect of saponins in stems and leaves of Panax notoginseng onmyocardial ischemic reperfusion injury in rats. Methods The rats were divided into six groups (the sham operation group, model group, DAXXK group, PNSSL 40, 80, 160 mg·kg-1 group) and continuous oral administration for 7 days. The ratmodel of myocardial ischemic reperfusion injury (MIRI) was developed by ligation of the left anterior descending coronaryartery the electrocardiogram (ECG), myocardial infarct size, staining with hematoxylin and eosin were observed. Theactivities of LDH、CK、AST、ALT in serum and SOD、GSH-Px、MDA in cardiac muscle tissue were detected by kit.Results Saponins in stems and leaves of Panax notoginseng in each dose (40, 80, 160 mg · kg-1) group significantlyreduced the myocardial infarct size and improved the ECG on ST segment, the myocardial damage was obviously reducedfrom the pathological section. Stems and leaves of Panax notoginseng in a dose of 160 mg · kg-1 lowered the serumactivities of LDH、CK and AST, contents of SOD and GSH-Px in a dose of 80 mg·kg-1 significantly lowered. Conclusions The results indicates that PNSSL have the effect against myocardial ischemic reperfusion injury and that the mechanismof pharmacological action related to the improvement of ECG changes, the stability of cell membrane, eliminate oxygenfree radicals and the reducing of inflammatory infiltration.
