Objective To establish a rat model of cardiac hypertrophy induced by isoproterenol(ISO),and to study its basic characteristics.Methods Cardiac hypertrophy was induced in rats with ISO. The model rats received subcutaneous injections of 5 mg/kg ISO every day for 14 days. Results The heart weight/body weight and left ventricular weight/body weight ratios in model rats were significantly increased. The serum hydroxyproline level was significantly increased,the superoxide dismutase level was significantly decre...
