目的 观察不同职业紧张人群体内清除自由基的能力。 方法 应用职业紧张量表 (OSI) ,对 2 48名不同职业紧张人群体内超氧化物歧化酶 (SOD)、血浆过氧化脂质 (L PO)进行测定。 结果 职业紧张暴露危险度高的人群体内 SOD低于职业紧张暴露危险度低的人群 (P<0 .0 1) ,而职业紧张暴露危险度高的人群体内 L PO高于职业紧张暴露危险度低的人群 (P<0 .0 1)。 结论 不同职业紧张人群体内清除自由基能力随职业紧张度的升高而有所下降。
Objective To observe the ability of free radical scavenging in different occupational stress groups. Methods Occupational stress test (OSI) was used to measure the levels of superoxide dismutase (SOD) and plasma lipid peroxidation (L PO) in 248 stress-induced occupational groups. Results The population with high risk of occupational stress exposure was lower than the population with low risk of occupational stress exposure (P <0.01), while the population with high occupational stress exposure was higher than the risk of occupational stress exposure Of the population (P <0. 01). Conclusion The ability of eliminating free radicals in different occupational stress groups decreased with the increase of occupational stress.
