Protective effect of tea polyphenol on rat myocardial injury induced by isoproterenol

Chinese Traditional and Herbal Drugs (China)(Apr) 1995

The ability of tea polyphenol to protect against myocardial injury induced by isoproterenol was studied in rats. Pretreatment with 10 mg/kg intraperitoneal tea polyphenol 5 days before isoproterenol administration decreased malonyldehyde concentration, and creatine phosphokinase and lactic dehydrogenase activities, and inhibited the extent of myocardial injury similar to the action of propranolol. Plasma renin activity was also decreased.
