[Protection of the pulmonary toxic effects of normobaric oxygen by inducers of cytochrome P450-linked monooxygenases].

Inducers of cytochrome P450-linked mono-oxygenases increase the normobaric oxygen tolerance of the adult rat. Pulmonary inducers, as 3-methylcholanthrene and beta-naphthoflavone permit the rat survival and simultaneously a decrease of pulmonary edema. Phenobarbital, an hepatic inducer had lesser effects both on survival rate and on pulmonary and lymphoïd oxygen toxicity.
