Figure 1: Epidermal thickness is increased in allergic contact dermatitis model mice. (a) Mice were sensitized with 100 μl of 5% oxa in ethanol on their shaved abdomen on day 0. Oxa challenges were performed on days 5, 7, 9, 11, and 13 after sensitization. (b) Ear tissues obtained from the mice on day 15 were subjected to H&E staining. (n=8–9/group). Left, control mouse; right, oxasensitized mouse; arrows, eosinophils. Scale bars, 10 μm.
