根据大多数研究者的意见,应将非结核和非肿瘤性的肺-支气管病变列为慢性非特异性肺部疾病。在该病患病率增高的原因中,应当指出有急性呼吸系统疾病的普遍性、流感病毒的反复流行、急性支气管肺部疾病治疗不及时和不彻底、由于机体反应性改变使抵抗力降低以及工业危害。肺炎的菌种对抗菌素和磺胺类药物的耐药性增高以及日常生活中变态反应因子的数目增多有极重要意义。 According to most investigators, non-tuberculosis and non-neoplastic lung-bronchial lesions should be classified as chronic nonspecific lung diseases. Among the reasons for the increased prevalence of the disease, the prevalence of acute respiratory diseases, the recurrent influenza virus, the inadequate and incomplete treatment of acute bronchopulmonary diseases, the decrease in immunity due to changes in the body’s reactivity, and Industrial hazards. Streptococcus pneumoniae strains of antibiotics and sulfa drugs increased resistance and increased daily life the number of allergic factors is extremely important.
