For studies of SAA deficiency, female Long-Evans adult rats were provided for 5 days with either a sulfur-deficient diet (38, 39) or a control diet supplemented with L-cystine and L-methionine. For this and the study below, tissues were perfused prior to collection to eliminate blood contamination. GSH concentration was analyzed in neocortex, hippocampus, thalamus, striatum, and liver by reverse-phase high performance liquid chromatography using ultraviolet detection and precolumn derivatization with 5,5'-dithio-bis(2-nitrobenzoic acid); the method was modified from that of Komura et al. (40).

To investigate the impact of Se status, weanling, male Long-Evans rats were fed for 6 weeks diets (38, 39) containing deficient, control, or supplemental levels of Se. Total GPX was measured in liver, thalamus, and neocortex by a modification of the method of Prohaska and Ganther (37).
