Figure 3. — Infiltration of mast cells in nasal mucosa and lung tissue of guinea pigs with AR. AR was induced by ovalbumin challenge. Histological analysis of (A) nasal mucosa and (B) lung tissue was performed by toluidine blue staining (magnification, ×400). The arrows indicate mast cells. The numbers of mast cells per high-power field in (C) nasal mucosa and (D) lung tissue were counted. Values are expressed as the mean ± standard deviation (n=10 per group). *P<0.05 compared with the control group. AR, allergic rhinitis.
