Increased Biliary Glutathione Disulfide (GSSG) Release in Chronically Ethanol-Treated Rats
Abstract
Recently, we have reported the observation of a substantial increase in biliary glutathione disulfide (GSSG) concentration in chronically ethanol-treated rats as compared to isocalorically pair-fed controls (Sies et al., 1979). Such information may be relevant to the discussion of liver damage related to chronic alcohol intake. The long-standing dispute in the literature regarding the occurrence of lipid peroxidation in alcoholism (cf. Plaa & Witschi, 1976) may become resolved when experimental approaches of non-invasive and non-destructive nature become increasingly employed. In this respect, GSSG release into bile may prove to be a particularly useful tool, complementing the method of measurement of alkane exhalation (Riely et al., 1974; Köster et al., 1977; Litov et al., 1978) and the new developments in the detection of ultraweak chemiluminescence (cf. Chance et al., 1978, for an overview).
