摘要
对5例单纯接触水泥生料粉尘工人尸检肺标本进行病理研究。主要尘性病变为尘斑、灶内的“水泥小体”、灶周肺气肿。部分病例尚有混合尘结节。每例均见慢性支气管炎及轻度间质弥漫纤维化。EDXA、SEM、SEM-EDXA及X线衍射方法对病变原位粉尘的元素成份及粉尘晶形进行了分析,并与现场的生料粉尘进行对比分析,结果证明水泥生料粉尘具有致尘肺作用,其病理类型属尘斑-气肿型尘肺,或混合型尘肺。
ive autopsized cases which only expo-sured to raw cement material dusts
werereported in this paper. Their charicteristicesof pathologic changes concerned with dusts
inthe lungs are as follows:(1) numerous dustfibrosis foci and focal emphysema are formedin
parenchyma of the lungs ,(2)there are “cement bodies”in dust fibrosis focal,(3)mixed dust
nodules are formed in the lungs of part cases,(4 )there are chronic bronchitisand slight
pulmonary fibrosis.By meansof EDXA,SEM,EDXA-SEM and X-raydiffraction,the elements of the
dust foci、the nodules were detected.The nodules in lung tissue were observed,the
resultsshowed that the elements of intrapul-monary dusts are similar to the environmen-tal raw
cement dusts. Therefore,we consi-dered that the pathologic changes in the lungs are caused by
the raw cement material dusts.
