A Representative photographs of dorsal skin of each group for monitoring the change in the lesion. B Histology of mouse skin sections stained with H&E. The space between red lines denotes the epidermal thickness. C Histology of mouse skin sections stained with toluidine blue for dermal mast cells. The red arrow heads indicate the mast cells (scale bar = 100 μm). D Dermatitis score measurements conducted over three weeks. E Comparison of epidermal thickness. F Measurement of the number of mast cells for each group. G The concentrations of IgE in blood serum retrieved from each group at W3. (n = 6). *, ** and *** indicate p < 0.05, p < 0.01 and p < 0.001, respectively
