THE INFLUENCE OF VARIOUS MONO-OXYGENASE INDUCERS ON RAT LIVER MICROSOMAL CHRYSENE OXIDATION
In view of their environmental occurrence and the lack of relevant data the induction effect of five heterocyclic aromatic compounds (two sulfur and three nitrogen containing pollutants) on rat liver microsomal chrysene oxidation was investigated and compared to the corresponding effects of two ubiquitous polycyclic aromatic hydrocarbons (benzo-(a)-pyrene and indeno-(1,2,3)-(cd)-pyrene.) The results obtained from incubations with liver microsomes of variously pretreated rats in presence of various inducers indicate a pronounced induction of chrysene metabolism, especially after treatment with the two sulfur heterocycles (benzo(b)naphtho (2,1-d)- and - (1,2-d)thiophene) and indeno (1-2,3-cd)pyrene. Thus, these three ubiquitous environmental pollutants must be considered as potent cocarcinogens.
