为研究卡介苗(BCG)活化的肺巨噬细胞对二氧化矽(SiO_2)的反应,进行了在体外培养条件下,BCG活化的肺巨噬细胞和正常肺巨噬细胞分别与SiO_2作用时,细胞显微结构和超微结构的形态学比较,并与体内实验的形态学改变相对照。体外培养显示,BCG活化的肺巨噬细胞和正常的肺巨噬细胞在形态学上具有很大的差异性。BCG活化的肺巨噬细胞既具有机能活跃的形态学特点,也具有机能损伤的
In order to study the response of BCG-activated pulmonary macrophages to silica (SiO 2), the effect of BCG-activated lung macrophages and normal lung-macrophages on the effect of SiO 2 Morphology of microstructures and ultrastructures is compared with that of in vivo experiments. In vitro culture showed that there is a great morphological difference between BCG-activated lung macrophages and normal lung macrophages. BCG-activated pulmonary macrophages have both morphologically active and morphologically impaired
