Activation of mast cell and eosinophil in the colonic mucosa. Representative photomicrographs (10 for each mouse) were taken from colonic mucosa of naïve mice (Fig 3A, 3C) and sensitized mice (Fig 3B, 3D). Bars stand for ratio of degranulation that was calculated with the numbers of degranulated granules divided by the numbers of total granules of mast cells (Fig 3E) and eosinophils (Fig 3F). *, p < 0.05, compared with naïve controls.
