Inhibitory potential of acetaminophen and o-, m-, p- aminophenols for development of gamma-glutamyltranspeptidase-positive liver cell foci in rats pretreated with diethylnitrosamine. 1985

Y Kurata, and H Tsuda, and S Tamano, and N Ito

The inhibitory potential of treatment with acetaminophen (AAP) and 3 different isometric forms of monoaminophenols (o-, m-, p-AP) for the development of gamma-glutamyltranspeptidase-positive (gamma-GT+) liver cell foci was examined in an in vivo short-term assay system. Rats were initially given a single intraperitoneal injection of diethylnitrosamine (DEN) and fed test compounds from week 2 until they were killed at week 6, all rats being subjected to two-thirds partial hepatectomy at week 3. All 4 compounds exerted obvious inhibition of the development of gamma-GT foci with both number and area (mm2) being reduced. AAP proved the most potent agent whereas dose-related inhibitory potential was observed within the 2 doses of p-AP treated.
