支气管哮喘(哮喘)是一个发病率很高的慢性呼吸道疾病,国内人群发病率约为2%,国外某些国家或地区儿童发病率高达10%以上。支气管哮喘若得不到有效治疗,可并发慢性支气管炎、肺气肿、肺心病,严重危害人们的健康。目前研究认为,哮喘主要病理变化为气道内的慢性非特异性炎症,导致气道反应性明显增高。而引起慢性炎症的原因既非细菌,也非病毒,而是在抗原或非抗原作用下促使气道内肥大细胞、嗜酸细胞、嗜碱
Bronchial asthma (asthma) is a chronic respiratory disease with a high incidence. The incidence of bronchial asthma (asthma) is about 2% in the domestic population, and the incidence in some foreign countries and regions is as high as over 10%. If bronchial asthma is not effective treatment, may be complicated by chronic bronchitis, emphysema, pulmonary heart disease, seriously endangering people’s health. The current study suggests that the main pathological changes of asthma in the airway chronic non-specific inflammation, leading to significantly increased airway responsiveness. The cause of chronic inflammation is neither bacteria nor virus, but in the antigen or non-antigen to promote airway mast cells, eosinophils, basophiles
