Role of vitamin C against bifenthrin induced oxidative damage in lungs of Wistar rats
Journal Title: Journal of Applied and Natural Science - Year 2016, Vol 8, Issue 1
Abstract
The aim of present study was to unravel the protective role of vitamin C on oxidative stress parameters in lung homogenates of bifenthrin intoxicated rats. Rats were divided into four groups. Group I served as control while group II animals were treated with bifenthrin @ 5.8mg/Kg/day. In group III, vitamin C was orally administered @ 60mg/Kg/day where as group IV received both vitamin C and bifenthrin @ 60mg/Kg/day and 5.8mg/Kg/day respectively. After 30th day of treatment, lung samples were taken and analysed for oxidative stress parameters. Significant (P<0.05) increase in lipid peroxidation was observed from control value of 4.80±0.39 to 7.90±0.50 in bifenthrin treated animals. Mean control values of SOD, GSH-Px and CAT were 0.55±0.05, 0.98±0.03 and 138.70±6.01 which were significantly (P<0.05) decreased to values of 0.27±0.0, 0.53±0.05 and 91.10±9.70 respectively in bifenthrin treated animals. The value of GST increased significantly (p<0.05) to 1.05±0.06 in bifenthrin administered animals from control value of 0.70±0.08. Pre-treatment with vitamin C in ameliorative group IV significantly restored the normal values of lipid peroxidation, SOD, GST and CAT but could not reverse the decreased values of GSH-Px. The present research is first of its type where in free radical generation due to bifenthrin –a commonly used insecticide was evaluated in lung homogenates when given orally which might be due to residues present in the lung. Besides it will be helpful in better understanding of toxicological profile of pyrethoids, the most commonly used insecticides.
