从作者测定129例哮喘病儿痰液中 IgA含量可以看出;哮喘发作时痰液中IgA含量比不发作时明显降低。支气管哮喘的发病机理与体内IgA缺少及溶酶体酶活力减弱有关系。IgA有较强的抗酶消化和还原分解能力,并具有抗细菌、病毒和毒素的活性。因此由支气管哮 IgA levels in sputum from 129 asthmatic children can be determined from the author’s findings; IgA levels in sputum at asthma attacks were significantly lower than those without seizures. The pathogenesis of bronchial asthma and lack of IgA in vivo and lysosomal enzyme activity relationship. IgA has a strong resistance to enzyme digestion and reduction and decomposition, and has anti-bacterial, viral and toxin activity. So by bronchial asthma
