为了阐明铅作业工人红细胞渗透抵抗力增强的机理,作者对19名在废铅片精炼工厂从业、32～73岁男性铅作业工人为对象;并以18名从事铁路建设工作、30～57岁的男工为对照,进行了红细胞计数、红细胞压积、红细胞平均容积、血铅、尿铅、尿粪卟啉、尿ALA、红细胞渗透抵抗力、血清卵磷脂-胆固醇酰基转移酶(LCAT)活性、以及红细胞膜的胆固醇含量和胆固醇-磷脂比率等项目的测定,结果:(1)铅作业工人组红细胞渗透抵抗
In order to elucidate the mechanism of enhanced resistance of lead workers to erythrocyte infiltration, the authors surveyed 19 lead workers who worked in lead scrap refinery factories and male workers aged 32-73, and 18 were engaged in railway construction work, with 30 to 57-year-old Male workers were used as controls, and red blood cell count, hematocrit, average volume of red blood cells, blood lead, urinary lead, urine coproporphyrin, urine ALA, erythrocyte osmotic resistance, serum lecithin-cholesterol acyltransferase (LCAT) As well as the red cell membrane cholesterol content and cholesterol-phospholipid ratio and other projects were measured, the results: (1) lead workers in the group of erythrocyte infiltration resistance
