BACKGROUND
Japanese cedars and grass are famous for causing pollen allergy with antigen. But recently, many other antigens causing pollen allergy are coming to the front. We investigated positive ratios of pollen antigens of the consultation patients.
METHODS
151 subjects (90 males and 61 females) were examined for allergic reactions by a scratch test. We used Yasueda's method to take pollen extracts.
RESULTS
A positive ratio of Cocksfoot (Dactylis glomerata) (51%) was higher than that of cedar (Cryptomeria japonica) (45%). Each positive ratio of birch (Betula platyphylla var. japonica), walnut (Juglans mandshurica), sheep sorrel (Rumex acetosella), oak (Quercus serrata) and willow (Salix spp.) was 13%, 8%, 9%, 11%, 10%, respectively. These were lower than that of Cocksfoot or cedar, but higher than that of Fungi: Alternaria, Candida and Aspergillus.
CONCLUSIONS
Grass (Gramineae) pollens and pollens of birch, walnut, sheep sorrel, oak and willow, which are in the air around the same time as grass pollens, are important in clinical medicine, because of their high positive ratio. And in this research, each positive ratio is overlapping, so it is necessary to search an antigen hemology.
