a) Photomicrograph showing a nasal epithelial cell immunostained for identification of MUC5AC+ cells. Nuclei are stained in purple/blue (arrow), cytoplasmic mucin MUC5AC is stained in brown. b) The percentage of MUC5AC+ nasal epithelial cells over the total number of nasal epithelial cells is significantly increased in the persistent untreated nonallergic rhinitis (NAR) patients compared both to control normal subjects (NS) and the persistent NAR patients under regular treatment with nasal glucocorticoids (NAR + GC), without any significant difference between control subjects and persistent NAR patients under regular treatment with nasal glucocorticoids. The immunocytochemical images in the right panel are representative of those from 12 control group subjects (c), 12 patients with persistent untreated NAR (d) and 12 patients with persistent NAR under regular treatment with nasal glucocorticoids (e). The images f, g and h are their representative negative controls (nonspecific mouse IgG). Original magnification: x400. Bar =50 μm
