[Imprinting effect of aroclor 1254 in the metabolic activation of benz[a]pyrene by rat liver tissue].
A well-known inductor of a system of multifunctional monooxygenases, the arochlor 1254, being applied to one-day rats produced an imprinting effect which was expressed in a strong and long-term increase in the metabolic activation of benzo(a)pyrene by the liver S9-fraction in the Salmonella/microsome test, as well as in the arylhydrocarbonhydroxylase activity. The imprinting was not revealed when the inductor was applied on the 9th day as well as it was not revealed for 2-acetylaminofluorene in the liver, or benzo(a)pyrene and 2-acetylaminofluorene in the kidneys, independently of the period of application.
