Abstract
(1) In a pathological study using the eosin stain test on nasal abnormalities in 343 out patient clinic patients from October 1997 to April 1998 a period in which pollen epidemics were not prominent, eosinophilic cells were not always found (60%) in allergic rhinitis or allergic sinusitis. In both diseases the color of the stained background was purple-pink to purple. Otherwise, in sinusitis the color was pink. (2) Ciliated columnar cells had a tendency to form clusters in allergic rhinitis and allergic sinusitis. Otherwise in sinusitis not clustered. (3) These findings show that nasal ciliated columnar cells behave like a kind of sensor of the nasal environment.
