Values are expressed as medians (quartile Q_0.25; quartile Q_0.75) or as average ± standard deviation, statistically significant differences between groups at a significance level of P<0.050 are marked with *. V, intervention group; P, control group; GSH, glutathione; NP-SH, non-protein thiols; NP-SS-NP, non-protein disulfides; G-SS-NP, glutathione-mixed disulfides; MDA, malondialdehyde; 3-NT, 3-nitrotyrosine.
