Hogg等于1968年最先提出小气道疾病的概念。他们把凡是具有小气道阻塞性病变的一类疾病统称为小气道疾病。许多学者对小气道疾病的病理变化进行了大量的观察,为我们进一步认识小气道疾病提供了重要的资料。目前国内有关小气道疾病的病理学观察材料甚少,为此我们准备扼要地介绍一下与小气道疾病病理学观察方法有关的几个问题。1.材料来源问题:用于观察小气道病理 Hogg is equal to 1968 first proposed the concept of small airway disease. They classify any type of disease that has obstructive airways disease as small airway disease. Many scholars have made a lot of observations on the pathological changes of small airway diseases and provided important information for further understanding of small airway diseases. At present, there are few materials for pathological observation of small airway diseases in our country. Therefore, we are going to briefly introduce some problems related to the method of pathological observation of small airway diseases. 1 source of material problems: for the observation of small airway pathology
