Cardioprotective Effect of Bioflavonoids against Isoproterenol Induced Cardiotoxicity in Rats

چکیده
The present study was undertaken to explore the cardioprotective potential of bioflavonoids against isoproterenol induced cardiotoxicity in rats. Cardiotoxicity was induced by isoproterenol (85mg/kg body weight) in animals. Blood biochemical, hematological parameters, urinalysis and histopathological studies were carried to assess the cardio protective effect. Isoproterenol administration induced significant cardiotoxicity in rats, which was evident from enhanced levels of glucose, cholesterol, triglycerides and calcium except sodium. Pretreatment with quercetin (50 mg/kg dose orally) significantly reversed isoproterenol induced cardiotoxicity than the silymarin (50 mg/kg dose orally). From the obtained results it may be concluded that quercetin exerted a significant cardioprotective effect against isoproterenol induced cardiotoxicity in rats than silymarin (p<0.001) for most of the blood biochemical parameters, mean corpuscular hemoglobin count as well as in attenuation of pathological changes in cardiac tissues.

In the present study, we investigated the effects of histidine and vitamin C (alone or in combination) treatments against isoproterenol (a β-adrenergic receptor agonist)-induced acute myocardial infarction in rats. We used propranolol (a β-adrenergic receptor blocker) to compare the results. Rats were given intraperitoneal injections of histidine (40 mg kg-1) and vitamin C (40 mg kg<...

Present study evaluated the cardioprotective effect of Andrographis paniculata (100, 200 or 400 mg/kg) against isoproterenol (85 mg/kg, b.w.)-induced cardiotoxicity referred as myocardial infarction in rats. Isoproterenol significantly (p < 0.05) decreased mean arterial pressure, heart rate, contractility and relaxation and increased left ventricular end diastolic pressure. Isoproterenol also s...
