Treatment of rats with 1-m-tolueneazo-2-naphthol (mTAN) caused marked increase in liver weight, microsomal 7-ethoxycoumarin O-deethylase activity and cytochrome P-450 content, with 2 nm hypochromic shift in CO difference spectrum. It decreased NADPH-cytochrome c reductase and aminopyrine N-demethylase activities. Treatment of
