After the left anterior descending coronary artery(LADCA) ligation, rats were orally administered with CNS for 7 consecutive days. CNS prevented MI-induced pathophysiological changes and significantly decreased plasma levels of myocardial enzymes, including creatine kinase MB isoenzyme(CK-MB), lactate dehydrogenase(LDH) and aspartate aminotransferase(AST). Further investigation revealed that CNS attenuated the production of inflammatory factors in plasma, including tumor necrosis factor-alpha(TNF-α), interleukin-6(IL-6) and interleukin-1β(IL-1β). Moreover, CNS treatment decreased the expression of caspase-3 at the mR NA level in infarct tissue. Our findings demonstrated that the anti-inflammatory and anti-apoptotic properties of CNS might confer its cardioprotection against MI in rats.展开更多
