Reduced glytathione (GSH) is the tripeptide of glycine, cysteine and glutamic acid and is widely distributed in the body. FSH has been reported to comprise at least 90% of the nonprotein sulfhydryl (NPSH). Although the role of GSH in the tissue has not been clearly established, it is known to be a cofactor for enzymes, a substrate in detoxifications, and a free radical scavenger.
Several investigators have reported that the level of NPSH, mainly GSH, in the tissue was decreased in several types of shock and that exogenous administration of GSH has beneficial effects on shock (1,2). This study was designed to evaluate the effects of GSH on the survival rate in mice and the hepatic energy metabolism in rats after administration of endotoxin. These results were compared with those of methylprednisolone sodium succinate (MP), since many investigators have reported that the large doses of glucocorticoid have beneficial effects in several types of shock in experimental animals and in man (3,4).
