Abstract
From October 1981 to September 1984, 97 cases of nasal allergy were observed. There were 75 cases of house dust allergy, 50 cases of Japanese cedar pollinosis, 19 cases of orchard grass pollinosis and 28 cases of ragweed grass pollinosis. Nineteen per cent of the patients had other allergic diseases and eighteen per cent had family histories of allergy. The results of a radio-allergosorbent test (RAST) using seventeen different grasses suggested the existence of crossallergenicity to many grass pollens in five of the cases. The seasonal variation of serum reaginic activity in Japanese cedar pollinosis was observed.
