    Abstract:
    The content of hepatic GSH was evaluated in rats after poisoning with white phosphorus. In addition, liver damage following the administration of the hepatotoxin was assessed by determining hepatic triglyceride accumulation. Experiments in parallel were carried out in an attempt to evaluate the enhanced susceptibility of hepatic tissue to peroxidative decomposition of unsaturated lipids 'in vitro', as measured by the production of TBA-reacting substances. Our data indicate that only in the early stage of intoxication is it possible to detect a slight decrease of GSH content in the liver, while during the subsequent stages the concentration of GSH was unaffected. At 6 hours of intoxication the level of hepatic triglycerides was significantly increased. Pretreatment with GSH was followed by an amelioration of fatty infiltration, but the content of hepatic GSH was unchanged. The production of TBA-reacting products was found enhanced only at 6 hours of intoxication. These results are discussed in relation to the role of lipid peroxidation in liver injury by white phosphorus.
