Fig. 2. HE and PAS staining of nasal mucosae (original magnification ×400). (A) The cytoplasm of eosinophils (black arrows) in the nasal lamina propria (LP) stains red by HE. (B) The cytoplasm of goblet cell in the nasal epithelial layer stains aubergine by PAS. Histopathology showed eosinophils accumulation and goblet cells hyperplasia in the nasal lamina propria in AR mother group and AR offspring group. HE, hematoxylin-eosin; PAS, periodic acid-schiff stain; AR, allergic rhinitis.
