| Outline of Final Research Achievements |
The condition to conduct basophil activation test with chronic cough patients were determined. Using this condition, more activation of basophil activated by cedar pollen antigen by polycyclic aromatic hydrocarbon could be confirmed. By contrast, the effect of heavy metals on activated basophil could not be observed.
The difference of constituents (polycyclic aromatic hydrocarbons and heavy metals) in ambient dust by the difference of particle size (total suspended particulate (TSP) and particulate matter 2.5 (PM2.5)) was observed. Seasonal variation of constituents in TSP or PM2.5 was also observed.

| Academic Significance and Societal Importance of the Research Achievements |
好塩基球活性化試験を用いて大気粉塵やその構成成分である多環芳香族炭化水素類により症状が影響を受けやすい慢性咳嗽患者の特徴が分かれば、予防や治療に役立てることができる。
大気粉塵の粒径の違いにより構成成分の違いがあることが分かったので、大気粉塵による健康影響についてもこの点を考慮して検討していく必要がある。
