Reduced glutathione (GSH), glutathione disulfide (GSSG) and the GSH:GSSG ratio in homogenates of heart (A) and skeletal muscle (B) of younger (3 mo) and older (20 mo) C57BL/6 and DBA/2 mice. Data are expressed as the mean ± SEM. of 5–8 mice of each strain. (* denotes p< 0.05 when compared with the young group of the same strain; ** indicates a significant difference from C57BL/6 of the same age. Individual comparisons were made within the Age × Strain interaction of each 2-way ANOVA).
