竹节参总皂苷预处理对冠脉结扎致大鼠急性心肌缺血损伤的影响
Effects of Total Saponin from Panax japonicus on Acute Myocardial Ischemia Injury Induced by Ligating Coronary Artery Left Anterior Descending Branch in Rats
摘要
Abstract
Objective: To investigate the cardioprotective effects of total saponin from Panax japonicus pretreating on acute myocardial ischemia injury induced by ligating coronary artery left anterior descending branch ( LAD) in rats. Methods:Rats were divided into sham group, model group and total saponin group. The treatment group was given total saponin of Panax japonicus. After pretreating for 7 days,the rats' acute myocardial ischemia model was induced by LAD. The electrocardiogram,hemodynamics,infarct size and histo-morphology were assessed 12h after LAD, the serum levels of phosphokinase (CK), lactate dehydrogenase ( LDH), superoxide dis-mutase (SOD) ,catalase (CAT) and malondialdehyde (MDA) were also measured. Results:Compared with the model group,total saponin from Panax japonicus significantly improved heart function, heart histomorphology, opposed ECG T wave decreased and decreased infarct size ; Remarkably decreased the contents of LDH , CK and MDA , increased the activity of SOD , CAT. Conclusion : Total saponin from Panax japonicus has cardioprotective effects on acute myocardial ischemic injury and the mechanism may be related to antioxidation.关键词
