How to use

In Vitro:

Astragaloside IV improves post-ischemic heart function and ameliorated reperfusion arrhythmias accompanied by a significant increase in myocardial antioxidative enzyme superoxide dismutase activity in rat hearts in vitro. While, Astragaloside IV's protective effect on heart function can be partially abrogated by the nitric oxide synthase inhibitor, Nomega-nitro-L-arginine methyl ester.

In Vivo:

Astragaloside IV significantly reduces infarct size in dogs subjected to coronary ligation in vivo. [1] Astragaloside IV attenuates isoproterenol-induced subendocardial necrosis, serum lactate dehydrogenase and creatine kinase activation, and lipid oxide product malondialdehyde formation in rats. It also reduces sarcoplasmic reticulum Ca(2+)-uptake ability and Ca(2+)-ATPase (SERCA2a) activity as well as SERCA2a mRNA expression in myocardial injury rats.
