Abstract
The present study used in vivo rat heart to investigate (1) whether Shen-Fu (SF), a traditional Chinese formulation comprising Radix Ginseng (RG) and Radix Aconitum Carmichaeli (AC), is protective against myocardium damage due to ischemia-reperfusion injury, and (2) whether the cardioprotective effect of SF is related to scavenging of hydroxyl radicals. The model of ischemia-reperfusion injury was established by ligation of left anterior descending coronary artery for 60 minutes followed by reperfusion for 240 minutes in anesthetized rats. The size of infarction and the pathologic changes of myocardium were observed. Lactate dehydrogenase (LDH) and creatine kinase (CK) in serum, the amounts of malondialdehyde (MDA) and superoxide dismutase (SOD) in myocardium were measured at the end of the reperfusion period. Pretreatment groups with SF (10 mg/kg), RG (9 mg/kg) and AC (1 mg/kg) inhibited the rise in MDA and LDH as well as CK, increased SOD activity, reduced the size of infarction, and improved the pathologic changes of myocardium during ischemia-reperfusion compared with the control group. The effect of SF is better than that of RG and AC. These results indicate that SF, RG and AC protect obviously myocardium against damage due to ischemia-reperfusion in rats. The cardioprotective effect of SF injection may be in part related to scavenging of hydroxyl radicals or inhibition of lipid peroxidation. SF is more effective than its separated herbal extracts prepared from RG and AC.
