为探讨焦炉逸散物及高温对作业工人血浆HSP70抗体滴度及肿瘤坏死因子（TNF）的影响，运用酶联免疫吸附鉴定法检测了85名焦炉工和73名非焦炉工血浆HSP70抗体滴度和TNF－α的含量。结果显示，焦炉工有51人出现1：10抗体阳性，21人出现1：20抗体阳性，分别占60％、28．2％；非焦炉工有23人出现1：10抗体阳性，11人出现1：20抗体阳性，分别占31．5％、15．1％，两组相比，差异有显著性（P＜0．05）。TNF的含量焦炉组明显高于对照组，差异有显著性（P＜0．05）。结果表明，焦炉逸散物和高温可导致机体受损、免疫功能发生紊乱。
To investigate the effects of coke oven fume and high temperature on plasma HSP70 antibody titers and tumor necrosis factor (TNF) in workers, 85 coke oven workers and 73 non-coke oven workers were tested for HSP70 by enzyme-linked immunosorbent assay Antibody titer and TNF-α content. The results showed that coke oven workers 51 1:10 antibody positive, 21 were 1:20 antibody positive, accounting for 60%, 28.2%; non-coke oven workers were 23 1:10 antibody positive, 11 There was a 1:20 antibody positive, accounting for 31.5% and 15.1% respectively. There was a significant difference between the two groups (P <0.05). The content of TNF in coke oven group was significantly higher than that in control group, the difference was significant (P <0.05). The results show that coke oven emissions and high temperatures can lead to body damage, immune dysfunction.
