Figure 4

Effect of NaHS on oxidative stress. The oxidative stress was determined by the protein expression of NOX-2 (a), NOX4 (b), P67phox (c), and nitrotyrosine (d) in renal artery and the plasma level of MDA (e). Data are means ± SEM. versus Sham; versus 2K1C vehicle. in each group for Western blotting; for MDA measurement.
