稀土在生物领域中应用研究进展

最近几年稀土在生物领域中的研究工作又有了新的重大突破和进展。纪云晶等从分子水平、细胞及亚细胞水平、整体动物实验和稀土接触人群肿瘤流调等方面进行了系统的研究，证明轻稀土确有抑癌作用。在环境研究方面解决了外源稀土的走向和回答了经多年施用稀土会不会污染地下水的问题。在机理研究方面提出了稀土可替换部分钙、铁等金属离子的“调节”论点和可消除机体内有害自由基的“清除”论点。

Recent Research Advance of Rare Earth in the Field of Biology

The study on rare earth application in the biological field has achieved significant progress in recent years.The results indicate that rare earth has the effect on inhibiting cancer.Using rare earth for many years does not cause the pollution for the underground water.The study on mechanism shows that rare earth can substitute partial metal ions such as Ca and Fe etc.,acting as regulating function.
