Abstract

細気管支に病変を有すると考えられる気管支喘息(細気管支閉塞型(II型)のアトピー型)と慢性閉塞性細気管支炎の違いについて臨床的に検討を加えた。(1)年令ではやや慢性閉塞性細気管支炎でやや低年令,発症年令では気管支喘息でやや低年令を示したが有意な差はみられなかった。(2)アレルギー学的検討では気管支喘息は明らかに1型アレルギー反応の関与が推測されたが,一方慢性閉塞性細気管支炎では1型アレルギー反応の関与はほとんどみられなかった。(3)Bronchoaiveolar lavage fluid(BALF)中出現細胞の検討では慢性閉塞性細気管支炎において気管支喘息に比べ好中球の有意の増加が観察され,出現率が55%以上の症例ではほぼ全例が慢性閉塞性細気管支炎であった。(4)換気機能による検討では%肺活量,1秒率では差は認められなかったが,気管支喘息で%V50,%V25のような細気管支の閉塞を示すパラメーターの低下傾向がやや高度であった。(5)胸部X線では気管支喘息では,X線上明らかなび四三陰影は認められず,一方慢性閉塞性細気管支炎では過膨脹所見も,び漫性情粒状陰影ともみられる症例が多く認められた。

Subjects with bronchial asthma with bronchiolar obstruction (type II) and cases with chronic obstructive bronchiolitis (COB) were compared by clinical characteristics and ezaminations. (1) The mean age was slightly younger in cases with COB than in asthma cases. The mean age at onset was slightly younger in asthma cases than in cases with COB. (2) The cases with asthma showed positive immediate allergic reactions. However the cases with COB didnot show any positive reactions. (3) The frequency of neutro phils in BALF was significantly higher in the cases with COB than in the cases with asthma. The majority of cases with COB showed the high frequency of neutrophils more than 55% in BALF. (4) In the ventilatory function tests the values of % FVC and FEV(1.0%) were not different between the cases with asthma and the cases with COB. The values of % V(50) and % V(25) which represent small airway obstruction were slightly more decreased in cases with asthma than in the cases with COB. (5) Any abnormalities in roentgenograms of the cases with asthma were not distinctly observed, while the cases with COB showed overinflation and diffuse small round opacities.
