职业性哮喘和职业性外源性变应性肺泡炎,都是因吸入特异的外源性过敏原而引起的二类重要的职业性免疫性肺疾病。由于新的化合物不断增多,能引起职业性哮喘和外源性变应性肺泡炎的物质日见增多。同时也由于人们对这类疾病认识的提高,患者人数日见增多。因而确诊职业性哮喘和职业性外源性变应性肺泡炎显得日趋重要。 Occupational asthma and occupational extrinsic alveolitis are two of the most important occupational immunological lung diseases caused by inhalation of specific exogenous allergens. As new compounds continue to proliferate, substances that cause occupational asthma and extrinsic alveolitis are on the rise. At the same time, the number of patients is increasing day by day due to the increasing awareness of such diseases. Therefore, the diagnosis of occupational asthma and occupational exogenous alveolar alveoli seem more and more important.
