支气管哮喘是一种比较常见的变态反应性疾病,一般认为本病与遗传因素有关。对于这种变态反应性疾病,如能查明引起发作的抗原(变应原),避免与其接触,或将其制成变应原液进行特异性脱敏是最理想的。但是,查明变应原是什么物质常常很困难,即或查明,想用来脱敏,也不一定能成功。因此,药物治疗仍然是支气管哮喘的主要治疗方法。 Bronchial asthma is a more common allergic diseases, the disease is generally believed that the genetic factors. For such an allergic disease, it is desirable to identify the antigen (allergen) that caused the attack, avoid contact with it, or specifically desensitise it as an allergen solution. However, it is often difficult to find out what the allergen is, or to identify, to desensitize it and not necessarily to be successful. Therefore, medical treatment is still the main treatment of bronchial asthma.
