①目的观察中国远洋船员血浆超氧化物歧化酶（ＳＯＤ）和丙二醛（ＭＤＡ）含量的改变。②方法采用分光光度比色法检测５３例远洋船员血浆ＳＯＤ活力和ＭＤＡ含量变化。③结果中国远洋船员血浆ＳＯＤ活力比陆地工作人群明显降低（ｔ＝７．９３，Ｐ＜０．００１）；而血浆ＭＤＡ含量则显著增高（ｔ＝３．５１，Ｐ＜０．００１）；连续海上航行大于１８０ｄ者的血浆ＳＯＤ活力明显低于连续海上航行小于１８０ｄ者（ｔ＝７．９１，Ｐ＜０．００１），而血浆ＭＤＡ含量比连续航行小于１８０ｄ者明显升高（ｔ＝２．４１，Ｐ＜０．０５）。④结论中国远洋船员机体抗氧化能力降低
Objective To observe the changes of plasma superoxide dismutase (SOD) and malondialdehyde (MDA) in Chinese offshore crew. Methods The spectrophotometric colorimetry was used to detect the changes of plasma SOD activity and MDA content in 53 ocean-going crew members. Results The plasma SOD activity of Chinese offshore crew was significantly lower than that of terrestrial working group (t = 7.93, P <0.001), but the plasma MDA level was significantly higher (t = 3.51, P <0.001) Plasma SOD activities were significantly lower than those of continuous sea voyages less than 180d (t = 7.91, P <0.001), but plasma MDA levels were significantly higher than those of continuous voyages less than 180d (t = 2). 41, P <0.05). ④ Conclusion China’s ocean-going crew reduced its antioxidant capacity
