蛇纹石

Results The cytotoxicity of chrysotile asbestos was in a dose and incubation time dependent manner. After 18 h incubation and at the dose of 250 μg/ml, the cell death rate and LDH content were increased significantly.

结果 纤状蛇纹石石棉对肺泡巨噬细胞的毒性存在着剂量-效应关系、时间-效应关系；125 μg/ml培养18 h后，细胞死亡率及LDH增加，500 μg/ml培养5 h后，细胞死亡率、LDH、MDA均明显增加，而SOD活力明显降低。
