Oxidative stress in the kidney cortex as assessed by determining the protein abundance of p22phox (A) and content H2O2 (B) in young (~3 month), old (30 month), old-ARB and old-ACEI male F344xBN rats. *p<0.05 vs. Young; n=8/group for all. Relative densities in protein abundance were determined by Western blot and normalized to Red Ponceau staining and an internal positive control. Kidney cortex H2O2 content was confirmed with catalase and normalized to mg of protein.
