【摘要】 本文报告了六种煤尘对大鼠肺巨噬细胞表面C₃受体Yc玫瑰花形成率的影响及其形成率与煤尘剂量-反应关系和煤尘对肺巨噬细胞表面形态扫描电镜观察。实验结果表明,六种煤尘组Yc玫瑰花形成率均较未染尘对照组明显增高（P<0.05、P<0.01）,其形成率与煤尘加入量呈明显的剂量-反应关系（P<0.05、P<0.01）,细胞表面形态的改变提示与煤尘毒性有关。更多还原

【Abstract】 The affection of six kinds of coal dusts on Yc rosette forming rate of rat’s alveolar macrophage surface C3 receptor, the relationship between Yc rcsette forming rate and the dose of coal dust and scanning electron microscope survey of macrophage surface shape affected by coal dust were reported. The experimental results showed that the Yc rosette forming rate of six experiment groups were all much higher than control group’s (P<0.05, P<0.01) and had obvious dose-effect relation (P<0.05, P<0.01) . The changes of macrophage surface shape suggested that they were related to the toxicity of coal dusts.更多还原
