本文对２６例过敏性支气管哮喘患者鼻分泌液中ＳＩｇＡ含量等进行了超速离心检测。结果表明：患者鼻分泌液中ＳＩｇＡ、ＩｇＡ、总ＩｇＡ含量均较正常人明显增加（Ｐ＜０．０５．＜０．０１．＜０．０５）．ＩｇＡ对白蛋白的相对分泌系数与正常人无显著差异（Ｐ＞０．０５）。结合其它研究认为过敏性哮喘患者呈粘膜ＳＩｇＡ免疫高反应状态。 In this paper, 26 cases of allergic bronchial asthma patients with nasal secretions SIgA content was ultracentrifuged. The results showed that the contents of SIgA, IgA and total IgA in nasal excretion of patients were significantly higher than those of normal controls (P <0.05, <0.01, <0.05). The relative secretion ratio of IgA to albumin was not significantly different from that of normal people (P> 0.05). Combined with other studies that allergic asthma was mucosal SIgA immune response status.
