摘　　要：目的观察不同品位煤尘对大鼠肺冲洗液中脂质含量的影响。方法实验分为9组 ,染尘时间分别为30、90、180和360天。结果各煤尘组大鼠肺冲洗液中脂质含量高于同期对照组 ,但又都低于同期石英组。煤尘组间的差异与煤变质程度的高低无关 ,与煤尘中游离二氧化矽含量高低有关。结论煤尘的致病性强弱与煤尘中SiO2 含量高低有关。To observe the effect of different grade coal dusts on lipid contents in the lung lavage of rats .Methods The experimental rats were divided into nine groups.All rats were killed by batch at intervals of 30,90,180 and 360 days after dust exposure.Results The results showed that the lipid contents in the lung lavage of rats in coal dust groups were higher than that of the physiological saline's and lower than that of the silica's in the same time.The difference in the coal dust groups did not relate to metamorphic degrees of coals, and did relate to the contents of SiO2.Conclusion The pathogenicity of coal dust has relation to the contents of SiO2 in the coal dust.
