title: The role of glutathione in the induction of hepatic gamma-glutamyltransferase by phenobarbitone.
abstract: The effect of hepatic glutathione concentration on the induction of gamma-glutamyltransferase (GGT) activity by phenobarbitone was investigated. A single dose of phenobarbitone 100 mg/kg weight was given to rats, and the concentration of hepatic glutathione and GGT activity were measured. The study results show a sharp drop of hepatic glutathione concentration within a few hours of injection. This drop precedes the increase in enzyme activity.
