Intoduction Glutathione &sulfide (GSSG) release frc3 liver [I ] has been evaluated as an indicator of oxidative stress, including lipid peroxidation (cf. hydroperoxide metabolism review in  )_ At present, the occurrence of enhanced rates of lipid peroxidation or of Ns02 production in the liver of rats c!lronically treated with ethanol is controversial (cf. review in ]3] and references therein) but appears to be a central concept in experimental pathology_ Therefore, we have applied a non-invasive approach and have examined the release of both oxidized and reduced ghrtathione from the liver of rats chronically treated, i.e., for 6 weeks with ethanol, essentially as in . According to the finding that GSSG release occurs into bile , measurements were carried out in bile samples obtained from anesthetized rats.
