Figure 4. Histology of allergic rhinitis and mev mice.

(A) Hematoxylin and eosin stains of the nasal cavity from controls, allergic rhinitis (OVA) and mev mice. (B) In allergic and mev mice, there is clearly increased nasal inflammation with eosinophilia, as compared to controls. (C) Epithelial thickness significantly increased in allergic mice compared with controls and mev mice (*p<0.05, **p<0.01, and ***p<0.001).
