Evaluation of the expression of NCAM, PSD-95, and GAP-43 by Western blot assay (n=32). (A) Western blot bands for NCAM, PSD-95, and GAP-43 expression. (B) Statistical analysis of NCAM protein expression. (C) Statistical analysis of PSD-95 protein. (D) Statistical analysis of GAP-43 protein. * P<0.05, ** P<0.01 vs. Control group, # P<0.05, ## P<0.05 vs. SCD group. 14N (28N), 14S (28S), and 14L (28L) represent the Control group, SCD group, and SCD+LEV group, respectively, at 14 days (28 days) after intragastric administration. Dose of VPA: 150 mg/kg/d, dose of LEV: 150 mg/kg/d.
