摘要
对21例接触水泥生产中各类粉尘的工人尸检表明肺内尘源性病变有:尘班、尘斑周肺气肿、有的尚伴有混合尘结节和大块纤维化。采用分析电镜及X 线衍射方法对肺内病灶中的粉尘作了定性、定量分析,证明了肺内粉尘与各自生前工作现场粉尘一致,从而证明了水泥生产中产生的各类粉尘都能致尘肺。
21 autopsies of workers exposed to various cement dust were performed.Characteristic pathologic changes caused by dust in the lungs were asfollows:The presence of humerous dust maculae and focal emphysema in theparenchyma of lungs.Mixed dust nodules and macrofibrosis were found insome cases.Qualitative and quantitative analysis of dust located at the fociwere performed with analytical electron microscope and X-ray diffraction.Results showed that the elements of intrapulmonary dust were same as theenvironmental dust.It indicated that several kinds of dust in the production ofcement may induce cement pneumoconiosis.
