AIRBORNE JAPANESE CEDAR POLLEN IN WAKAYAMA PREFECTURE IN 1986

Abstract

Recent years have seen an increasing frequency in Japanese cedar pollinosis, which has become a social problem. This trend is true in Wakayama Prefecture. It is well known that the mechanism of onset of this disease is typical type I allergy involving Japanese cedar pollen and specific Ig antibody. Determination of the quantity of airborne Japanese cedar pollen in various parts of Wakayama Prefecture should be helpful in estimating the incidence of this disease and in taking preventive measures. Pollen sampling devices were installed on the roofs of representative hospitals in various parts of Wakayama Prefecture to determine the amount of airborne Japanese cedar pollen. This paper describes the results with some consideration of factors related the amount of airborne pollen.
