为探讨多环芳烃对焦炉工外周神经功能的影响,选取焦炉工炉顶、炉侧、炉底工种各15名作为研究对象。收集工人的班后尿,用高效液相色谱法检测尿中1-羟基芘的水平,同时测定研究对象的双侧正中神经和尺神经的感觉和运动神经(排除受伤神经)传导速度(SCV和MCV)、远端潜伏期(SL和ML)。结果显示焦炉工人尿中1-羟基芘水平显著高于对照组,各接触组感觉和运动神经传导速度、远端潜伏期与对照组比较差异无统计学意义,提示多环芳烃未引起焦炉作业工人外周神经传导速度的改变。
In order to investigate the effect of PAHs on the peripheral nerve function of coke oven workers, 15 workers were selected as the top, the furnace and the bottom of coke oven workers respectively. The urinary levels of 1-hydroxypyrene were measured by high performance liquid chromatography (HPLC). The sensory level of bilateral median nerve and ulnar nerve and the motor nerve (excluding injured nerve) conduction velocity (SCV and MCV), distal latency (SL and ML). The results showed that the level of urinary 1-hydroxypyrene in coke oven workers was significantly higher than that in the control group. There was no significant difference in sensory and motor nerve conduction velocity and remote latency between the exposure groups and the control group, suggesting that polycyclic aromatic hydrocarbons did not cause coke oven operation Workers peripheral nerve conduction velocity changes.
