Oxycarotenoid Lutein Reverses the Toxicity Induced by Carbofuran in Wistar Rats

Abstract

Objective: Elucidation of the protective effect of lutein against carbofuran induced toxicity in Wistar rats. Methods:Male Wistar rats were assigned into 5 groups of five animals. Group I normal received sunflower oil, Group 2 received carbofuran (5 mg/kg b. w.) alone. Group 3-5 received carbofuran plus lutein (50, 100 and 200 mg/kg body weight) respectively. Carbofuran and lutein administration were continued for 14 d. Neurobehavioural markers such as rotarod, grip strength test and pain threshold tests were carried out. After sacrifice, tissues were analysed for marker enzymes, antioxidant enzymes as well as oxidative stress markers.Results: Low dose of carbofuran was found to produce neurobehavioral problems as seen from the decreased retention time during rotarod test, endurance capacity in grip strength test and increased endurance capacity in pain threshold test. They were found to be significantly reversed by oral lutein administration. Administration of lutein restored the decreased acetylcholinesterase produced by carbofuran. Serum and tissue marker enzymes such as lactate dehydrogenase, creatine kinase and gamma-glutamyltransferase, which were increased by carbofuran were decreased by lutein administration. Lutein administration also reduced oxidative stress parameters which were increased by carbofuran. Conclusion:The results showed that carbofuran induced toxicity in male Wistar rats was reversed by carotenoid lutein.

Efficacy of Oral Glutathione Addition in Lutein Supplementation on Contrast Sensitivity Improvement in Dry Age-Related Macular Degeneration: A Randomized Controlled Trial

“…Antioxidant properties of lutein were observed in a study by Purushothaman et al as carbofuran-induced oxidative stress in rats was attenuated by lutein administration. Lutein reduced the neurotoxicity and tissue toxicity as observed from the elevated serum and tissue levels of acetylcholinesterase and decreased levels of creatine kinase, lactate dehydrogenase, and γ-glutamyltransferase [20].…”
