Figure 2. Effects of high-salt feeding and tempol treatment on oxidative stress markers evaluated by urinary 8-hydroxy-2'-deoxyguanosine (OHdG) excretion (A), dihydroethidium (DHE) staining in glomeruli (B), and p22phox mRNA expression in glomeruli (C) at 4 weeks after high-salt treatment.

Data are expressed as means ± S.E.M.; n = 6 per group. *P<0.05, **P<0.01, compared to high-salt group.
