Abstract |
The initiating and promoting activities of 1.2-dibromoethane in rat liver were investigated using the enzyme-altered foci bioassay. The incidence of gamma-glutamyl-transpeptidase (GGT)-positive foci was used as an early histochemical marker for hepatocarcinogenesis. To determine the initiating activity of 1.2-dibromoethane, the halogenated hydrocarbon was administered orally in corn oil as single or multiple doses (60 or 120 mg/kg) either before or after partial hepatectomy. The animals were then given a promoting regimen of 500 ppm phenobarbital in their drinking water. No increase in the incidence of GGT-positive foci was observed in any of the 1.2-dibromoethane initiation groups. |
