Three-Year Statistical Study of Japanese Cedar Pollinosis

Abstract

Japanese cedar pollinosis was studied in 193 new outpatients (78 males, 115 females; 53 children, 140 adults) treated in our outpatient clinic from January 1987 to December 1989.
Japanese cedar and Japanese cypress pollen counts changed each year. The pollen count was highest in 1988, followed by that in 1989 and then that in 1987. The number of new outpatients with Japanese cedar pollinosis showed same tendency. More adults than children had positive specific IgE antibody levels to Japanese cedar pollen. Most of the new outpatients with Japanese cedar pollinosis were also sensitive to other antigens.
