磨工尘肺的病理观察──光镜、扫描电镜及x线能谱分析

对两例飞机工业磨工尸检肺进行病理观察。应用ＳＥＭ－ＥＤＸＡ检测了病灶原位化学元素组分，证实肺内粉尘是吸入之生产粉尘。肺病变以尘斑（并灶周气肿为主，伴有轻度间质纤维化。认为磨工尘肺是由多种金属成分及ＳｉＯ２综合作用所致的混合性尘肺。

A PATHOLOGICAL STUDY OF POLISHER PNEUMOCONIOSIS

Two autopsy cases of polisher pneumoconiosis were studied. By means ofenergy. diapensive x-ray analysis (EDXA) and scaning electron microscopy(SEM),the elements in the dust foci of the lungs were tested. Results indicated that the elements of intoapulmonary dusts were just the same as those of the workshop. Thepathologic changes of the lung consisted of dust meculae, perifoeal emphysema andmild fibrosis. The pulmonary lesions oblaind might be induced by a combind actionof metals including silica dust.
