利用~(99m)Tc 胶体硫和~(197)Hg-BMHP 对152名氯乙烯接触工人进行肝脾闪烁图检查,其中包括聚氯乙烯生产工人124名,工龄0.5～21年;聚氯乙烯加工厂工人28名,工龄1.5～18.5年。101名聚氯乙烯生产工人(81%)和18名聚氯乙烯加工厂工人(64%)闪烁图有明显的病理性改变,有30名证明有严重的改变。闪烁图中最常见的病理变化是脾内胶体积聚的增加、脾大、肝内胶体硫摄取不匀。加工厂工人的闪烁图改变比生产厂工人轻微,闪烁图阳性者,BSP 试验阳性者71例(57%),阴性者30例(24%);闪烁图阴性者,BSP 试验阳性者8
A total of 152 vinyl chloride workers exposed to ~ (99m) Tc colloidal sulfur and ~ (197) Hg-BMHP were used for liver and splenomegaly scintigraphy, including 124 PVC production workers with a working age of 0.5-5 years. Polyvinyl chloride 28 factory workers, length of service 1.5 to 18.5 years. There were significant pathological changes in 101 PVC producers (81%) and 18 PVC workers (64%), with 30 demonstrating serious changes. The most common pathological changes in the flicker map is an increase in the accumulation of colloids in the spleen, with splenomegaly and intrahepatic colloid sulfur uptake unevenly. 71% (57%) were positive for BSP test, and 30 (24%) were negative for those who showed slight changes in the scintillation pattern of workers in the processing plant than those in the manufacturing plant who were positive for scintigraphy; those with negative scintigraphy and those with positive BSP test 8
