Abstract Treatment of chickens for up to 20 weeks with 0.1,1.0, and 10mg/kg doses of benzo(a)pyrene (BaP) or 7,12-dimethylbenz(a)anthracene (DMBA) resulted in significant increases in incidence and size of atherlosclerotic lesions at the 2 higher doses. Maximal lesion formation for birds treated chronically with BaP occurred at 1mg/kg and development of lesions in birds treated with DMBA was roughly linear over the dose range. Administration of 10mg/kg for 20 weeks of BaP or DMBA produced lesions in 75 and 89% respectively of chickens. Lower doses of BaP or DMBA produced smaller percentages of lesions, and the 0.1mg/kg dose produced no increase in lesion incidence. At equimolar doses DMBA was more potent than BaP. Administration of a single dose of BaP or DMBA followed by weekly doses of 12-0-tetradecanoylphorbol 13-acetate (TPA) for 20 weeks did not result in enhancement of lesion formation. Blood cholesterol was not significantly altered after treatment with BaP, DMBA or TPA.
