国內外学者都认为,在矽肺发生与发展过程中,石英粉尘颗粒的被吞噬和游离与肺泡巨噬细胞的吞噬和崩解是一个很重要的环节,有关肺内粉尘清除和巨噬细胞消长、崩解的报道也屡见不鲜,但多系光镜和扫描电镜观察资料,仔细地研究吸入肺内粉尘储留清除与巨噬细胞形态变化的材料颇感不足。 Domestic and foreign scholars believe that in the occurrence and development of silicosis, the engulfment and dissociation of quartz dust particles and the phagocytosis and disintegration of alveolar macrophages are a very important link. With regard to lung clearance and macrophage depletion, Disintegration reports are also uncommon, but more light microscopy and scanning electron microscopy observations, a careful study of inhaled lung dust retention and macrophage morphological changes material quite inadequate.
