Effects of PEA-m on Mast Cells. Toluidine blue staining was used to identify mast cell infiltration (encircled in red), characterized by dark lilac blue granules: (A) sham group; (B) PO group; (C) PO + PEA-m post-treatment group; (D) PO + PEA-m pre + post-treatment group. (E) Mast cell number per unit area of tissue (mast cell density). Figures are illustrative of at least three distinct experiments. Values are means ± standard error of the mean (SEM) of five animals for each group. *** p < 0.001 vs. sham, ## p < 0.01 vs. PO.
