the activity of nadph-cytochrome c reductase and the content of cytochrome b5 were enhanced by o-toluidine only in the liver . m-toluidine enhanced the glutathione s-transferase activity while the p-isomer increased both the epoxide hydrolase and the glutathione s-transferase activities . p-toluidine decreased the ahh and aminopyrine demethylase activities and the cytochrome p-450 content .
