(A) Hepatic reduced glutathione (GSH). (B) Hepatic oxidized glutathione (GSSG). (C) GSH/GSSG ratio (n=16). (D) Liver citrate synthase activity (n=9-10). Reduced (GSH) and oxidized (GSSG) glutathione levels were determined in liver homogenates as described by Teare et al (1993). Citrate synthase activity was determined by the conversion of oxaloacetate and acetyl-CoA to citrate and SH-CoA and monitored by the appearance of the thionitrobenzoic acid product at 412 nm.
