Induction of rat hepatic UDP-glucuronosyltransferases by dietary ethoxyquin

Dietary administration of 0.5% ethoxyquin markedly enhanced rat hepatic UDP-glucuronosyltransferase activities. Both 3-methylcholanthrene- and phenobarbital-inducible glucuronidation reactions were stimulated by the antioxidant. In contrast, phenobarbital-inducible bilirubin glucuronidation was not affected by ethoxyquin.
