Fig. 3.

Superoxide dismutase (SOD) activity (A; n = 4–5) and protein expression of SOD1 (B; n = 5–6), SOD2 (C; n = 6), and SOD3 (D; n = 6) in the small renal vessels from NORM, ANG, and ANG + TTx. (A) SOD activity was normalized to mg protein, and black inserted bars are SOD activity with potassium cyanide treatment. (B, C, D) Relative densitometric unit units of the enzymes were normalized to that of β-actin. ^*p ≤ 0.05 vs. ANG.
