title: Induction and promotion of gamma-glutamyltranspeptidase-positive foci in the rat liver by methylglyoxal.
abstract: The effect of pre-(initiation) and post-(promotion) administration of methylglyoxal (MG) on the induction of gamma-glutamyltranspeptidase (GGT)-positive foci in the liver of F344 male rats was investigated. GGT-positive foci were produced in dose-related amounts by 0.05 and 0.2% MG in drinking water, either when administered to uninitiated rats or when given in the promotion phase.
