Induction of detoxification enzymes is a major mechanism whereby a wide variety of chemical agents protect rodents against neoplastic, mutagenic, and other toxicities of carcinogens. The enzyme NAD(P)H:(quinone acceptor) oxidoreductase (EC 1.6.99.2) can protect against the toxicities of quinones and
