为揭示粉尘作业工人血清超氧化物歧化酶活性的变化规律及其影响因素，对某市码头澳粉作业工人血清SOD活性进行规定，结果显示：该作业工人SOD活性显著升高，且高浓度接尘组显著高于低浓度组；肺纹理增加组显著高于肺纹理正常组；吸烟、饮酒的工人亦明显上升，且接尘与吸烟、饮酒三者存在协同作用关系．
In order to reveal the variation regularity and its influencing factors of serum SOD activity in dusty workers, the serum SOD activity of Australian workers in Australia was determined. The results showed that the activity of SOD in the workers was significantly increased, Dust group was significantly higher than the low concentration group; lung texture increased significantly higher than the normal lung tissue group; smoking, alcohol consumption workers also increased significantly, and the dust and smoking, drinking there is a synergistic relationship between the three.
