稀土在生物体内抗氧化作用的研究进展

Advance in Studies on Rare Earth Against Oxidation in Organism

在体内,自由基的产生和清除存在着动态平衡,过量自由基可引起机体的氧化损伤。本文就稀土的抗氧化作用及其可能作用机制进行了综述,重点阐述了稀土的低剂量抑制过氧化和高剂量促进过氧化作用,并对稀土抗氧化作用的阈剂量及作用机制进行了展望,旨在为其作为一种新型抗氧化剂提供理论依据。

The production and cleanup of free radical exists in homeostasis in vivo, the excessive free radical can damage the organism. The review will dwell on the anti-oxidative ability of rare earth and its possible mechanism, emphasizing on its low dosage suppressing oxidation and high dosage promoting oxidation,looking forward to the threshold dosage and the mechanism of rare earth resisting the oxidation, aiming at offering the theoretical foundation for it as a kind of new-type antioxidant.
