目的 探讨二氧化硅 (SiO2 )刺激肺巨噬细胞 (PAM)上清液在Ⅰ型肺上皮细胞损伤中的作用。方法 分别用体积分数为 5 %和 10 %不同剂量的SiO2 刺激大鼠 (SD)肺泡PAM上清液作用于貂肺上皮细胞 (CCL - 6 4) ,采用四唑盐 (MTT)比色法测定其增殖效应。结果 在
Objective To investigate the effect of silica (SiO2) on pulmonary epithelial cell injury induced by pulmonary macrophage (PAM) supernatant. Methods The supernatant of alveolar pulsed alveolar was stimulated by SiO2 (5% and 10%, respectively) on mink lung epithelial cells (CCL - 6 4) Its proliferative effect. The result is
