Alterations in antioxidant enzyme activities and oxidative damage in alcoholic rat tissues: protective role of Thespesia populnea.

Recent advances in our understanding of the pathogenesis of alcohol-induced hepato-renal injury and the development of new approaches to its treatment have been reported in various works. This study involves alcohol-induced oxidative stress linked to the metabolism of ethanol involving both mitochondrial and peroxisomal fractions of liver and kidney. Alcohol treatment resulted in the depletion of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR), Glutathione-S-Transferase (GST) activities, and reduced glutathione (GSH) content, higher level of malondialdehyde (MDA) and lower levels of protein carbonyls (PC) causing malfunction of hepatic and renal tissues, when compared to control rats.
