Effect of alpha-lipoic acid on lipid peroxidation and anti-oxidant enzyme activities in diabetic rats

Abstract

1. Oxidative damage has been suggested to be a contributory factor in the development and complications of diabetes. Recently, alpha-lipoic acid (ALA) has gained considerable interest as an anti-oxidant. Various studies have indicated the anti- oxidant effects of ALA and its reduced form dihydrolipoic acid. Therefore, it appears that these compounds have important therapeutic potential in conditions where oxidative stress is involved. The aim of the present study was to investigate the effect of ALA supplementation on lipid peroxidation and anti-oxidant enzyme activities in various tissues in diabetic rats.
