煤工尘肺病理诊断体视学研究

Study of Stereoscopy Pathologic Diagnosis of Coal Workers' Pneumoconiosis (CWP)

应用体视学方法,对经GB8783—88诊断的21例煤工肺脏大体标本的煤尘灶、灶周肺气肿、尘肺结节进行了立体计量及分布特点的研究。结果表明均随期别增加而增多,其中煤尘灶居首,各期之间体积分数值皆有非常显著性,可做为煤工尘肺病理诊断分期指标。Ⅰ、Ⅱ期煤工尘肺煤尘灶、尘肺结节上、中叶高于下叶,中、外带多于内带。肺后部尘肺结节多于前部,各期灶周肺气肿无统计学差异。

Studies on three-dimensional quantity anddistributional characteristics of coal-dust mac-ule, perifocal emphysema and dust-nodule onlarge specimen of lungs have been made withthe method of stereoscopy in 21 cases thathave been diagnosed as CWP in KMA accor-ding to GB 8783-88. The results shows thatthe coal-dust focus, perifocal emphysema anddust-nodule are increasing more with the pr-ogress of disease stages. Coal-dust focus ranksfirst and the value of volume fraction betweenstages is remarkable. In stages Ⅰ and Ⅱ coal-dust focus and dust-nodules in upper andmiddle lobes are more than that in the lowerone and more in middle and outer portionthan that in inner zone, more dust-nodules onback part than frant that in the front.
