[A pathological study of finished-cement pneumoconiosis: report of 3 autopsy cases].
Three autopsy cases exposed only to finished-cement dusts were studied. Pathologic changes relevant to cement dusts in the lungs were similar, including distribution of numerous dust macules and focal emphysema formed in the parenchyma of lungs. Additionally, "cement bodies" were obtained in the dust macules. By means of electron diapensive X-ray analysis (EDXA), EDXA-SEM (scanning electron microscopy) and X-ray diffraction, the elements of dust foci and digested concentrates of the lungs were measured, and the morphology of dust granules was studied. Results indicated that the elements of intrapulmonary dusts were just the same as those of finished-cement dusts. Therefore, the pulmonary lesions obtained were considered to be induced by finished-cement dusts.
