Abstract

目的 通过对矽肺患者血清氧化功能指标的检测,以了解矽肺患者机体的抗氧化状态.方法 选择矽肺患者及接尘者共143例为暴露组,以健康体检者56人为对照组,留取两组无溶血、脂浊及黄疽的血清,测定血清中谷胱甘肽(GSH)水平、超氧化物歧化酶(SOD)活力及丙二醛(MDA)水平,并比较两组间血清指标的差异.结果 暴露组血清中GSH、MDA水平及SOD活力分别为(14.17±0.91)mg/L、(14.43±2.05)nmol/ml、(49.03±6.12)U/ml,均明显高于对照组[分别为(4.74±0.66)mg/L、(4.93±0.66)nmol/ml、(28.62±3.04)U/ml],差异均有统计学意义(P 0.05).GSH水平及SOD活力随着病程延长呈下降趋势,而MDA水平则无明显变化.结论 矽肺患者血清中GSH、MDA水平及SOD活力增高,且血清中GSH、SOD与患病年限呈负相关。
