title: [A comparative study of the individual characteristics of the excretion of metabolites of benzo(a)pyrene and its carcinogenic effect in rats].
abstract: Nineteen outbred LIO rats received a single intraperitoneal injection of 200 mg/kg benzo(a)pyrene (BP) in sunflower oil. Levels of excretion of a BP activation product 7.8-BP-dihydrodiol and deactivation product 3-hydroxy-BP showed significant individual variations. Half the animals developed intraperitoneal sarcoma at various stages of the experiment. A direct correlation between urine 7.8-BP-dihydrodiol excretion level and tumor latency was established. The value of metabolite excretion level monitoring for making individual prognosis of BP carcinogenic effect is discussed.
