title: Preventive effect of rutin on lipids, lipoproteins, and ATPases in normal and isoproterenol-induced myocardial infarction in rats.
abstract: The present study was designed to evaluate the preventive role of rutin on lipids, lipoproteins, and ATPases in normal and isoproterenol (ISO)-induced myocardial infarction in rats. Rutin (40 and 80 mg/kg) was orally administered to rats for a period of 42 days. After that period, isoproterenol (150 mg/kg) was injected subcutaneously to male wistar rats at an interval of 24 h for 2 days. The weight of heart and the concentrations of total cholesterol, triglycerides, and free fatty acids were increased significantly (p < 0.05), and the concentration of phospholipids was decreased significantly (p < 0.05) in the heart of ISO-treated rats. ISO-treated rats also showed a significant increase (p < 0.05) in the levels of total cholesterol, triglycerides, phospholipids, low-density lipoprotein cholesterol (LDL-C), and very low-density lipoprotein cholesterol (VLDL-C) with a significant decrease (p < 0.05) in high-density lipoprotein cholesterol (HDL-C) level in serum. The activities of sodium potassium dependent adenosine triphosphatase (Na(+)/K(+) ATPase) and magnesium-dependent adenosine triphosphatase (Mg(2+) ATPase) were decreased significantly (p < 0.05), and the activity of calcium-dependent adenosine triphosphatase (Ca(2+)ATPase) was increased significantly (p < 0.05) in the heart in ISO-treated rats. Pretreatment with rutin at doses of 40 or 80 mg/kg to ISO-treated rats showed a significant (p < 0.05) effect in all the parameters studied. Oral administration of rutin to normal rats did not show any significant effect. Thus, the results of our study show that pretreatment with rutin maintained the levels of lipids, lipoproteins, and ATPases in ISO-induced myocardial infarcted rats. The observed effects might be due to the antioxidant potential of rutin.
