Danggui Buxue Tang Inhibits 2,4-Dinitrochlorobenzene: Induced Atopic Dermatitis in Mice

Figure 5

The effects of DBT on mast cell infiltration in ear tissue. Ear sections were stained with toluidine blue to analyze mast cell infiltration in normal control mice (a); sensitized control mice (b); 3 g/kg DBT (HD3, c) or 10 g/kg DBT (HD10, d) (100x magnification); mice per group for all groups. Arrows indicate mast cells. The mast cells were measured under 10–15 high-power fields (HPFs) (e). Data are presented as means ± SEM. , versus sensitized control mice.
