Therapeutic Effects of Methyl Protodioscin for Myocardial Infarction in Rats / 中药新药与临床药理

ABSTRACT

Objective To study the therapeutic effects of methyl protodioscin (MPD ) on myocardial infarction in rats. Methods Rat models of myocardial infarction were induced by ligation of coranary artery. Then myocardium infarction area and the vasoactive substance were measured to evaluate the therapeutic effect of MPD on acute myocardial infarction in rats. Results Compared with the control group,MPD lessened the myocardial infarction size dramatically,inhibited the increase of CK and LDH ,lowered the increased MDA content level and improved the activity of SOD and NO. Conclusion MPD reduces the level of myocardium enzyme and the myocardial infarction size,and increases the capability of clearing oxygen free radical and function of the vascular endothelial cell. MPD by intravenous injection has a better effect than that by oral use.
