本文调查接触煤焦沥青的炭素作业工人173例和对照组163例细胞生物膜损伤二项重要指标——谷胱甘肽过氧化物酶活性(GSH—Px)和过氧化脂质(LPO)水平。结果:炭素作业工人LPO水平呈增高趋势,但GSH—PX水平未下降。提示本组观察的炭素沥青作业工人机体对抗不饱和脂肪酸产生氧化脂质反应能力是健全的。
This paper investigated 173 coal workers exposed to coal tar pitch and 163 control cells in the biofilm injury two important indicators - glutathione peroxidase (GSH-Px) and lipid peroxidation (LPO) levels . Results: The LPO level of carbon workers showed an increasing trend, but the level of GSH-PX did not decrease. Prompted that the observed carbon bitumen workers in this group of organisms against unsaturated fatty acids oxidation lipid reaction is sound.
