肺泡巨噬细胞(PAM)通过吞噬作用清除外来吸入性颗粒。在此过程中,可产生大量对生物体有害的活性氧,因此需要抗氧化物质以减轻活性氧的危害。谷胱甘肽(GSH)具有一定的抗氧化作用。有关受毒物刺激后肺GSH的释放研究较少,本研究观察了不同粉尘颗粒对PAM
Alveolar macrophages (PAM) remove foreign particles by phagocytosis. In the process, a large amount of reactive oxygen species harmful to living organisms can be generated, and thus antioxidants are needed to reduce the harm of reactive oxygen species. Glutathione (GSH) has a certain antioxidant effect. There are few studies on the release of GSH from the lungs after being stimulated by toxicants. In this study, the effect of different dust particles on PAM
