The present study was designed to examine the in vivo effect of ebselen on reperfusion injury to the liver. Lipid peroxidation and glutathione (GSH) levels of the reperfused liver tissue, as well as hepatocellular damage (serum GOT, GPT, LDH, and histology) were examined. The production of thiobarbituric acid-reactive substance did not increase in the 60-min-reperfused liver tissue in the ebselen group. Ebselen completely suppressed the increase in lipid hydroperoxide production in the reperfused liver tissue. After the tissue GSH level was reduced by buthionine sulphoximine, ebselen failed to suppress the lipid peroxidation of the reperfused liver tissue. Serum levels of GOT, GPT, and LDH, histological analysis, and the tissue level of GSH clearly showed that ebselen protects the reperfused liver tissue, both structurally and functionally. We conclude that ebselen's primary effect on ischemia-reperfusion injury may be due to a GSH-peroxidase-like effect and/or the inhibitory effect of leukocyte infiltration.
