Protective Effects of 7-Hydroxycoumarin on Dyslipidemia and Cardiac Hypertrophy in Isoproterenol-Induced Myocardial Infarction in Rats.

This study evaluates the protective effects of 7-hydroxycoumarin (7-HC) on dyslipidemia and cardiac hypertrophy in isoproterenol (ISO) induced myocardial infarction (MI) in rats. Rats were pre- and co treated with 7-HC (16 mg/kg) daily for 8 days. ISO (100 mg/kg) was subcutaneously injected into rats on seventh and eighth days to induce MI.

Activation of β1-adrenoceptor triggers oxidative stress mediated myocardial membrane destabilization in isoproterenol induced myocardial infarcted rats: 7-hydroxycoumarin and its counter action.

Activation of β1-adrenoceptor stimulates myocardial membrane destabilization in isoproterenol induced rats. Male albino Wistar rats were pre and co-treated with 7-hydroxycoumarin (16mg/kg body weight) daily for 8 days. Myocardial infarction was induced into rats by the subcutaneous administration of isoproterenol (100mg/kg body weight) at an interval of 24h daily for a period of two days (7th and 8th day).

Thymol attenuates inflammation in isoproterenol induced myocardial infarcted rats by inhibiting the release of lysosomal enzymes and downregulating the expressions of proinflammatory cytokines.

Inflammation plays an important role in the development of myocardial infarction (MI). The current study dealt with the protective effects of thymol on inflammation in isoproterenol (ISO) induced myocardial infarcted rats. Male albino Wistar rats were pre and co-treated with thymol (7.
