摘要
本文通过对62名电焊工和35名对照者血中超氧化物歧化酶(SOD)、巯基(-SH)和发锰的研究。发现电焊工血中SOD、-SH、发锰值均显著高于对照组(P<0.05)。发锰与SOD及-SH的相关分析表明:两组的发锰与SOD(r=0.5239和r=0.3558)均呈显著性相关(P<0.01和P<0.05);而两组发锰与-SH的相关性(r=0.1867和r=0.0398)均无显著性差异(P>0.05)。故认为电焊烟尘可引起作业者血中SOD的活性和-SH含量的增加,这可能与电焊烟尘中锰等因素的影响有关。
Superoxide dismutases (SOD), sulfhydry (-SH) in blood and manganese in hair (MnH) were analysed for 62 welders and 35 normal workers. The results showed SOD, -SH and MnH in welders were significantly higher than control group. We also examined the association of MnH from 62 welders and 35 controls with the correspouding SOD and -SH, it showed a correlation with SOD of 0.5239 and 0.3558 but there was no relation with -SH. This study suggested that welding fume induce to increase SOD and -SH in blood of welders and may be associated with Mn.
