最近的研究证明,肺内“石棉小体”并非石棉肺独有的病理特征,有很多种粉尘吸入可在肺内产生一种与“石棉小体”相同的所谓“含铁小体”;甚至大多数城市居民即使不接触任何石棉粉尘,肺组织内也同样可有此类“含铁小体”存在。至于肺内“含铁小体”数量的多寡则与年龄、性别、居住条件、特别是职业性有害粉尘的接触有关。作者介绍一种简单的“含铁小体”检出方法——痰液微过滤法,并对阳性检出率及其与石棉接触的关系等进行了研究。
Recent studies have demonstrated that the “asbestos bodies” in the lungs are not the unique pathological features of asbestosis. There are many kinds of dust inhalation that can produce a so-called “iron-containing bodies” in the lungs that are the same as “asbestos bodies”; even Most urban residents, even if they do not come into contact with any asbestos dust, may have such “iron bodies” in the lung tissue. The number of “iron-containing bodies” in the lungs is related to age, gender, living conditions, and occupational harmful dust in particular. The authors introduced a simple method for the detection of “ferrous bodies” - microfiltration of sputum, and studied the positive detection rate and its relationship with asbestos exposure.
