Abstrakt: Fipronil is a relatively new insecticide of the phenpyrazole group. Fipronil-induced effects on antioxidant system and oxidative stress biomarkers are yet to be studied in vivo. The present study was undertaken to evaluate fipronil-induced alterations in the blood biochemical markers and tissue antioxidant enzymes after oral exposure in mice and to explore possible protective effect of pre-treatment of antioxidant vitamins against these alterations. Mice were divided into eight groups containing control, test and amelioration groups. Mice in the test groups were exposed to different doses of fipronil, i.e., 2.5, 5 and 10 mg/kg bw, respectively for 28 days. Mice in the amelioration groups were treated with vitamin E or vitamin C (each at 100 mg/kg) 2 h prior to high dose (10 mg/kg) of fipronil. Fipronil exposure at three doses caused significant increase in the blood biochemical markers, lipid peroxidation and prominent histopathological alterations; while level of antioxidant enzymes was severely decreased both in kidney and brain tissues. Prior administration of vitamin E or vitamin C in the fipronil exposed mice led to decrease in lipid peroxidation and significant increase in activities of antioxidants, viz., glutathione, total thiol, superoxide dismutase and catalase. Vitamin E and vitamin C administration in fipronil exposed mice also improved histological architecture of the kidney and brain when compared with fipronil alone treated groups. Thus, results of the present study demonstrated that in vivo fipronil exposure induces oxidative stress and pre-treatment with vitamin E or C can protect mice against this oxidative insult.
