Cytoplasmic Total, Oxidized and Reduced Glutathione Levels and GSH/GSSG Redox Ratio in the tube cells treated with DEP ± NAC.

a is significantly different from the samples to DEP (0 μg/mL) in upper column or to NAC+DEP (0 μg/mL) in lower column (p < 0.05) b is significant difference between DEP and NAC+DEP samples (p < 0.05). Total GSH, total glutathione; GSSG, oxidized glutathione; GSH, reduced glutathione. Values are given as mean ±SD of n = 3 experiments and duplicate measurements. The concentrations of DEP used are 1, 10, and 100 μg/mL, NAC is 10 mM. DEP (0 μg/mL) presents as the negative control.
