โœฆ Synopsis


Metabolism of the polycyclic hydrocarbon benzo(a)pyrene (BP) to watersoluble products was measured in cultured human leukoeytes from 35 healthy volunteers. The classification into 3 different groups with respect to degree of BP metabolism fits that obtained in a previous population and family study, where only the ratio of aryl hydrocarbon hydroxylase (AHH) activity of 3-methylcholanthrene (3MC) treated cultures to the activity of control cultures was measured. These data support previous observations that metabolism of polycyclic hydrocarbons is under genetic control.

Zusammen/assung. In der vorliegenden Arbeit wurde der Metabolismus des carcinogenen Kohlenwasserstoffes Benzpyren zu wasserl6sliehen Produkten in Leukocytenkulturen von 35 gesunden Individuen untersucht. Hinsichtlich der Geschwindigkeit im Benzpyrenmetabolismus kSnnen 3 Gruppen unterschieden werden. Diese Einteilung ist in vSlliger t~bereinstimmung mit der einer Populations-und Familienstudie, wo das Verh~ltnis der ,,Aryl-Hydrocarbon-Hydroxylase"-Aktivit~t yon 3-Methylcholanthren-behandelten Leukocytenkulturen zu der von Kontrollkulturen bestimmt wurde. Diese Ergebnisse stfitzen die Beobachtung, dal3 der Metabolismus yon carcinogenen Kohlenwasserstoffen unter genetischer Kontrolle ist.
