a) The percentage of neutrophils on total number of nasal inflammatory 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. b) The percentage of eosinophils on total number of nasal inflammatory cells is significantly increased in the persistent untreated NAR patients compared both to NS and NAR + GC, without any significant difference between control subjects and persistent NAR patients under regular treatment with nasal glucocorticoids. c) The total number of nasal epithelial cells is significantly increased in the persistent untreated NAR patients compared both to NS and NAR + GC, without any significant difference between control subjects and persistent NAR patients under regular treatment with nasal glucocorticoids. d) The percentage of goblet cells on the total number of nasal epithelial cells is significantly increased in the persistent untreated NAR patients compared both to NS and NAR + GC, without any significant difference between control subjects and persistent NAR patients under regular treatment with nasal glucocorticoids
