[Microsomal monooxygenases upon inhalation exposure to pseudocumene and durene].

This paper gives data on the levels of cytochromes of B5, P450, P420, P450 + P420, on the rates of amidopyrinum N-demethylation and aniline n-hydroxylation in the tissues of the lung, liver, kidney of experimental rats upon acute and chronic (4-month) inhalation exposure to pseudocumol and durol at a concentration of 10 mg/m3. Acute and chronic inhalation exposures to the xenobiotics in this concentration result in activation of microsomal monooxygenases in the tissues of experimental rats in relation to the type of exposure.
