気管支肺胞洗浄液（BALF）中に高度の好中球増多の見られたアトピー型喘息の一例

気管支肺胞洗浄液（BALF）中に高度の好中球の増多が見られ，治療により臨床症状の軽快と共にBALF中の好中球の減少を認めたアトピー型喘息の一例を経験した。経過中5回施行したBALF中の好中球百分率はそれぞれ65.4％，56.2％，42.4％，5.6％，5.6％であり，4回目，5回目では著明な好中球減少を認めた。本症例の如き症例は今後増加することが予想され，その発症病態を含め今後さらに症例を重ねて検討して行く必要があると 考えられた。

The clinical course and characteristics of a case with atopic asthma, showing marked neutrophilia in BALF and severe asthma attacks, were observed the frequency of neutrophils in BALF decreased followed by the improvement of her asthma attacks with therapy. The frequency of neutrophils in BALF was 65.4% at the initial stage before the therapy and decreased to 5.6% at attackfree stage after the therapy. The changes in frequency of neutrophils in BALF, obserbed in this case, should be noticed, because the cell in BALF were hardly affected by any treatment.
