The ability of hexachlorobenzene and lindane in diethylnitrosamine (DENA) pretreated rats
to enhance the incidence of gamma-glutamyltrans-peptidase (GGTase)-positive foci was …

The initiating and promoting activities of 1, 2-dibromoethane in rat liver were investigated
using the enzyme-altered foci bioassay. The incidence of γ-glutamyl-transpeptidase (GGT) …

The effect of 200 ppm hexachlorobenzene (HCB) in the diet on hepatic gamma glutamyl
transpeptidase (GGT) levels was examined in F344 male and female rats. During early …

The effect of concurrent administration of phenobarbital on the hepatocarcinogenicity of N-
nitrosodiethylamine (diethylnitrosamine; DENA) in rats was investigated by determination of …

The incidence of gamma-glutamyltranspeptidase (GGT)-positive foci induced by 0.3

An initiation/promotion bioassay for chemical carcinogens and tumor promoters has been
developed in rat liver using presumed preneoplastic lesions, foci of gamma …

The effect of di (2-ethylhexyl) phthalate (DEHP), a widely used plasticizer and environmental
contaminant, on the emergence of gamma-glutamyltranspeptidase positive (GGT+) …

The dose-dependent and sex-related effects of 3 hepatocarcinogens were investigated by
