We observed the number of causative pollens in allergic rhinitis in Kyoto from 1992 to 1994. Japanese cedar pollen was detected from February to the beginning of April. Cupressaceae pollens in April, Alnus Japonica and Fagaceae pollens from April to July, Pinaceae pollens from April to June and Gramineae pollens from May to September.
We counted the number of these pollens over 3 years. Japanese cedar count was 297/cm2; 1366/cm2; 220/cm2, Cupressaceae count was 145/cm2; 2064/cm2; 61/cm2, Alnus Japonica and Fagaceae were 548/cm2; 751/cm2; 693/cm2, Pinaceae count was 1138/cm2; 1233/cm2; 1028/cm2, Gramineae count was 388/cm2; 293/cm2; 103/cm2. The dispersion pattern of Cupressaceae pollen was similar to that of Japanese cedar. However, the other pollens were constant during these 3years.
