The results of this study revealed that the administration of the capsule showed the following pharmacological functions in experimental aninials:reducing acute myocardlal infarction size (MJS) of rats by nitroblue tetrazolium technique and the change of ST section and T wave in electrocardiograph (ECG) by i.v. injection of 0.5 U/kg of hypophysine

raising the tolerance of mice to hypoxia

abating the release of creatine phosphokinase (cpk) from the myocardial ischaemia tissue in rats

increasing 86Rb intake of the heart and the myocardial nutritional blood flow in mice. In twenty-four open-chest anesthetized dogs

the capsule expanded coronary arteries

increased the coronary volume of blood flow

and decreased the total peripheral vascular resistance(TPVR).
