SOD1 and autism: Meanwhile, the induction of autism by PPA resulted in significantly decreased in the serum levels of IL-10 (p = 0.0031), GSH (p = 0.0322), and T-SOD activity (p = 0.0207) (21.48 ± 4.90 ng/L, 6.68 ± 2.51 μmol/L, and 72.27 ± 13.85 U/mL) compared with those in the control group (40.25 ± 7.57 ng/L, 14.45 ± 5.03 μmol/L, and 106.38 ± 22.22 U/mL) (Figures 2A–F).
