Rutin potentially attenuates fluoride-induced oxidative stress-mediated cardiotoxicity, blood toxicity and dyslipidemia in rats

Abstract

This study was undertaken to evaluate cardio protective effect of rutin against sodium fluoride (NaF)-induced oxidative stress-mediated cardiotoxicity and blood toxicity. Cardiac injury was induced by daily administration of NaF 600 ppm in distilled water for four weeks. The animals exposed to NaF exhibited a significant increase in levels of cardiac serum markers, lipid peroxidative markers, serum total cholesterol, LDL, triglycerides and decrease in HDL levels. Decrease in hematological parameters, namely hemoglobin, red blood cells, mean corpuscular volume, mean corpuscular hemoglobin (MCH), MCH count and increase in white blood cells and erythrocyte sedimentation levels were also observed. Marked histopathological lesions and increased DNA fragmentation in cardiac tissues were observed. Activity of antioxidants-catalase, superoxide dismutase and reduced glutathione contents were decreased (p < 0.01), whereas lipid peroxidation product (malondialdehyde) was increased. A significant decrease in body and heart weight was also observed. Treatment with rutin effectively ameliorated the alterations in the studied parameters of rat through its antioxidant nature. There was also significant improvement in hematological parameters. Thus, results of this study clearly demonstrated that treatment with rutin against NaF intoxication has a significant role in protecting F-induced cardiotoxicity, blood toxicity and dyslipidemia in rats.
