Abstract excerpt
4-Nitroquinoline-N-oxide (4-NQO) was administered to lacZ mice at a concentration of 20 microg/ml in drinking water for 2 weeks, and the mutagenic fractions in a number of organs were assayed. The mutant fractions in tongue, esophagus and other pooled oral tissues were, respectively, 117+/-26, 73+/-15, and 48+/-15 mutants/10(5) plaque-forming units (pfu) (ca. 15-40xbackground). 4-NQO was not mutagenic in lung,...
