DEX-Gel reversed the effects of OVA-induced histopathological changes on nasal mucosa. A Representative HE-stained images of nasal mucosal thickness and eosinophils. Arrows point to eosinophils. B Representative TB-stained images of mast cells. Arrows point to mast cells stained purple. C Representative PAS-stained images of goblet cells. Arrows point to goblet cells stained purple. Scale bars = 5 mm on the left side of (A, B, C); Scale bars = 50 µm on the right side of (A, B, C). Data are expressed as mean ± SD. *P < 0.05, **P < 0.01 and ***P < 0.001, significantly different from the ANOVA group
