(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.
Key words : eosin stain test, nasal ciliated columnar cell, sensor of the nasal environment
