Effects of H2S on intracellular reduced GSH and T-SOD activity.

(a,b) Intracellular reduced GSH and T-SOD activity were reduced in lung tissue of smokers and COPD (n = 4–5 patients in each group). (c,d) NaHS up-regulated intracellular GSH and SOD activity in CS stimulated U937 cells (n = 6–7 experiments). *P < 0.05, **P < 0.01 vs. control; #P < 0.05; ##P < 0.01 vs. CS.
