Histological analysis of nasal mucosa tissue. Eighteen hours after the OVA challenge, the nasal mucosa tissues were removed and histological analysis was conducted. The nasal cavities were decalcified and fixed. The sections of control (NC; PBS-induced, PC; OVA-induced) mice, and AR mice treated with EBT or Dex were stained with H&E (A, magnification x 200; B, magnification x 200) or PAS (C, magnification x 100).
