HISI treatment prolong the survival time of mice in toxic condition induced by sodium nitrite and duration of electrocardiograph in trachea closed mice .HISI could obviously improve the ischemic electrocardiogram T-wave induced by Pituitrin.ST segment drifts on electrocardiogram in acute myocardial ischemia rats induced by Isoprotereno were obviously opposed by administration of HISI. The myocardial infarction areas, releasement of lactic dehydrogenase 、 creatine phosphokinase significantly increased in myocardial ischemia dogs, HISI treatment prevented these effects .
