A mouse lung tumor model of tobacco smoke carcinogenesis.

Abstract excerpt

We examined the possibility of developing an animal model of tobacco smoke carcinogenesis. Male Balb/c and SWR mice were exposed for 5 months to tobacco smoke (6 h/day, 5 days/week; average concentration, 122 mg/m(3) of total suspended particulates [TSP]) followed by a recovery period of 4 months in air. In both strains there was an increase in lung tumor multiplicities and incidence, although statistical...
