Concentration of antiinflammatory and pro‐inflammatory cytokines 120 d after SCI. The levels of IL‐4 (A) and IL‐10 (B) in the INDP group were significantly higher than those observed in PBS‐immunized rats. In contrast, the levels of TNF‐α (C) were significantly lower in rats treated with INDP compared to those immunized with PBS alone. Bars represent the mean ± SD of five rats. This is one representative graph of three determinations. *Different from PBS, P < .05; Student's t test
