摘要 本文用Smith消化法提取肺内粉尘及含铁小体,并对粉尘进行X线衍射物相分析。结果发现含铁小体的检出率为100%,含铁小体数量为1~15000个/克肺湿重,含铁小体等于和大于100个/克肺湿重的占59.04%,含铁小体透明轴心多于黑色轴心,59%的病例透明轴心的含铁小体为黑色轴心的两倍以上。而含铁小体的量又与有、无尘肺病有明显差异。国外研究将100个/克肺湿重做为职业性接触与非职业性接触石棉的界限。本研究50%的病例含铁小体高出100个的1~150倍,是值得认真探讨的。通过对肺内提取之粉尘做X线衍射物相分析发现,粉尘内有d=8.434,d=8.261的X线衍射峰,通过X线衍射矿物鉴定,属角闪石族石棉。它可能是形成含铁小体轴心的因素之一。 In this paper, ferruginous bodies were extracted from lung tissue by Smith's digest-lve method, and analyse'dthe component ofpulmonary mineral dus tby X-ray diffraction.The detectable rate of ferruginous bodies is 1050cases is 100% by digestive method. There are1~15,000 ferruginous bodies/g wet lung, Theferruginous bodies of 59.04% cases are morethan 100 bodies/g wet lung tissue. There aretwo kinds of core, the black and transparent,thl number of the later one were twiceor more than black core in 59% casesThere is significant difference of ferruginousbodies in pneumoconiosis and no pneumocon-iosis. Experts of abroad thought that 100asbestos bodies/g wet lung be limited value toseparate exposed and unexposed occupationalgroup. There are 1 to 150 times greater than100 bodies/g wet lung in 5O% cases. We foundthat there are the X-ray diffraction peaks ofd=8.434 and d=8.261. The dust is classifiedto amphibole. It may be one of factors offerruginous bodies' core formation.
