Study on antioxidant effect of Astragalus polysaccharide / 中国药理学通报

Xanthine-Xanthine oxidase ( X-XOD) added to the culture medium of cultured cardiac cells in rats may damage cell membrane. Electrophysiological findings indicated that APA, MDP, OS,Vmax, were decreased and the SDF was increased. Astragalus polysaccharide (APS) could protect the cells from being damaged by X-XOD. APS recoverted all the de-creased cardiac functional parameters in free-radical-damaged rats by X-XOD. APS had anti-free-radical damage action on the cultured my-ocardiocytes and the myocardial contractility of the isolated rat working heart.
