Protective effects of thymol on altered plasma lipid peroxidation and nonenzymic antioxidants in isoproterenol-induced myocardial infarcted rats
This study evaluates the protective effects of thymol on altered plasma lipid peroxidation products and nonenzymic antioxidants in isoproterenol (ISO)‐induced myocardial infarcted rats. Male albino Wistar rats were pre and cotreated with thymol (7.5 mg/kg body weight) daily for 7 days. ISO (100 mg/k...

Zusammenfassung: | This study evaluates the protective effects of thymol on altered plasma lipid peroxidation products and nonenzymic antioxidants in isoproterenol (ISO)‐induced myocardial infarcted rats. Male albino Wistar rats were pre and cotreated with thymol (7.5 mg/kg body weight) daily for 7 days. ISO (100 mg/kg body weight) was subcutaneously injected into rats on 6th and 7th day to induce myocardial infarction (MI). Increased activity/levels of serum creatine kinase‐MB (CK‐MB), plasma thiobarbituric acid reactive substances, lipid hydroperoxides, and conjugated dienes with decreased levels of plasma reduced glutathione (GSH), vitamin C, and vitamin E were observed in ISO‐induced myocardial infarcted rats. Pre and cotreatment with thymol (7.5 mg/kg body weight) showed normalized activity of serum CK‐MB and near normalized levels of plasma lipid peroxidation products, reduced GSH, vitamin C, and vitamin E in myocardial infarcted rats. Furthermore, the in vitro study on reducing power of thymol confirmed its potent antioxidant action. Thus, thymol protects ISO‐induced MI in rats by its antilipid peroxidation and antioxidant properties. © 2012 Wiley Periodicals, Inc.
