Abstract The possible role of glutathione-dependent enzymes in the liver and kidney of the freshwater fish Channa punctatus has been studied after exposure to arsenic trioxide for different durations. Activities of glutathione-S-transferases, glutathione peroxidase, glutathione reductase, and catalase decreased in the liver and kidney as a result of the initial increase in arsenic concentration in the liver and kidney. However, during longer exposures, a decline in arsenic concentration corresponded with improved enzyme activity. Because arsenic manifests its toxicity by inducing oxidative stress, the antioxidant enzymes, especially the glutathione-dependent enzymes, play a protective role in arsenic toxicity.
