The reason is biological
GSH depletion In the combination of glutathione and glutathione, the catalytic activity of glutathione-S-transferase and the combination of exogenous chemicals or their metabolites, which can decrease the toxicity and increase the polarity, is one of the most important methods in the biological transformation.When is suitable for the reaction of exogenous chemicals in large doses, may make the depletion of glutathione, a metabolic saturation (metabolic saturation), and in combined with the amount of time no longer increases with the increase of the exogenous chemicals dosage.The corresponding exogenous chemical toxicity, then the dose-response curve with a low dose not, the poison dynamics is characterized by nonlinear dynamics.GSH depletion mixed order is some kind of exogenous chemicals dosage is too large, also can be due to another foreign competition the combination effect of chemicals, or because of undernutrition or tissue damage that glutathione reduced supplies.GSH depletion have any condition that causes can make the original tolerance dose of poison
