Ferulic Acid modulates altered lipid profiles and prooxidant/antioxidant status in circulation during nicotine-induced toxicity: a dose-dependent study.
Nicotine, an active ingredient of tobacco smoke, is known to induce hyperlipidemia and disturb the prooxidant-antioxidant status. In our study, ferulic acid, a naturally occurring nutritional compound, was tested for its antioxidant and antihyperlipidemic property in a dose-dependent manner against nicotine-induced toxicity in female Wistar rats. We tested three different doses of ferulic acid-10 mg, 20 mg, and 40 mg/kg body weight-for their protective effects. The activities of biochemical marker enzymes lactate dehydrogenase and alkaline phosphatase, levels of peroxidative indices (thiobarbituric acid reactive substances and hydroperoxides), nitric oxide, and circulatory lipids (cholesterol, triglycerides, free fatty acids, and phospholipids) were increased significantly in the nicotine-treated group when compared to normal, which were brought down in ferulic acid-treated groups. The antioxidant status (superoxide dismutase, catalase, glutathione peroxidase, vitamin E, and reduced glutathione) was found to be decreased in the nicotine-treated group, and was significantly increased in ferulic acid-administered groups. Further, ferulic acid also positively modulated the nicotine-induced changes in the micronutrients (zinc and copper) level. The dose 20 mg/kg body weight was found to be more effective than the other two doses. Our data suggest that FA exerts its preventive effects by modulating the degree of lipid peroxidation, antioxidant status, lipid profiles, and trace element levels during nicotine-induced toxicity.
