Objective To evaluate effect of safflor yellow on acute myocardial ischemia and hemodynamics in dogs. Methods The model of myocardial ischemia was induced by ligating coronary artery in dogs. Safflor yellow was administered intravenously .The effects of safflor yellow on the extent and scope of myocardial ischemia,the extent of myocardial infarction,the levels of creatine kinase and lactic acid dehydrogenase in serum and the hemodynamics were examined. Results Safflor yellow could reduce the degree of myocardial ischemia,decrease the activity of creatine kinase and lactic acid dehydrogenase in...
