Table 1.

The activities of catalase (CAT), glutathione peroxidase (GPx), glutathione (GSH), and protein oxidation (Po) levels in renal tissue of control (n = 6), NAD (n = 8), DXR (n = 8), and DXR plus NAD groups (n = 8). *P = 0.001; control versus NAD, DXR, and N + D, **P = 0.105; control versus N + D.
