The effects of PEA/Pol on PARP and nitrotyrosine expression after DNBS injection. Immunohistochemistry for PARP was evaluated in sham (A), DNBS+Veh (B), DNBS+Pol (C), DNBS+um-PEA (D), and DNBS+PEA/Pol (E). The results are expressed as % of positive pixels (F). Images are figurative of at least three independent experiments. Immunohistochemistry for nitrotyrosine was evaluated in sham (G), DNBS+Veh (H), DNBS+Pol (I), DNBS+um-PEA (J), and DNBS+PEA/Pol (K). The results are expressed as % of positive pixels (L). Images are figurative of at least three independent experiments. Values = means ± SEM of six animals in each group; *** p < 0.001 vs. sham; ^## p < 0.01 vs. DNBS, ^### p < 0.001 vs. DNBS.
