Figure 7. TP supplementation enhances antioxidative potential in the SN and HIPP of aged male rats. (A) MDA levels, (B) GSH/GSSG ratio, (C) GSH-PX activity, (D) CAT activity, (E) CuZn-SOD activity, and (F) Mn-SOD activity in the SN. (G) MDA levels, (H) GSH/GSSG ratio, (I) GSH-PX activity, (J) CAT activity, (K) CuZn-SOD activity, and (L) Mn-SOD activity in the HIPP. Data are expressed as the mean ± S.D. (n = 8/group). *P < 0.05, **P < 0.01 (Bonferroni test).
