摘要
目的了解电焊作业有害因素对血清抗氧化系统的影响。方法以65名电焊作业工人为接触组,55名不接触职业病危害因素的工人为对照组。对两组人员的血清总抗氧化能力(T-AOC)、超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GSH-Px)活力及丙二醛(MDA)含量进行测定分析。结果接触组工人血清T-AOC、SOD活力较对照组降低,差异有显著性(P<0.05)。结论电焊作业产生的锰尘、噪声等职业有害因素可影响工人体内抗氧化系统。
Objective To study the effects of welding exposure on workers＇ antioxidant system. Methods Observation was conducted on the activities of total antioxidant capacity （T-AOC）, superoxide dismutase （SOD）, glutathione peroxidase （GSH-Px） and the concentration of malondialdehyde （MDA） in serum of 65 welders and 55 controls. Results It was found that the activities of T-AOC and SOD were significantly lower in welders than those in controls （P 〈 0.05）. Conclusions It suggests that chronic exposure to manganese-containing dust, noise and other hazards produced by welding process might have certain effects on antioxidant system of exposed workers.
