支气管哮喘主要分为外源性和内源性两种。外源性哮喘见于特应性体质,即对外界的过敏原能立即产生过敏与反应性抗体者;他们对某些物质呈立即皮肤试验阳性反应,血清免疫球蛋白E(IgE)抗体的浓度大多增加。内源性哮喘皮肤试验呈阴性反应,IgE浓度正常或减少,发作时常较外源性者严重而持久,为在肺功能上鉴别两种哮喘,作者等选出292名外源性与63名内源性哮喘患者,在作检查前停止治疗(强的松除外)12小时后,作动态与静态肺功能检查,包括动脉
Bronchial asthma is divided into two types of exogenous and endogenous. Exogenous asthma seen in atopic constitution, that is, the external allergen can immediately produce allergic and reactive antibodies; they are positive for immediate skin test on some substances, serum immunoglobulin E (IgE) antibody concentrations mostly increase. Endogenous asthma skin test was negative, normal or decreased IgE concentration, seizures are often more serious and persistent than exogenous, in order to distinguish between the two kinds of asthma in lung function, the author selected 292 exogenous and 63 Patients with asthma who have asthma who have been stopped for treatment (except for prednisone) 12 hours after the start of the test are enrolled in dynamic and static lung function tests including arterial
