摘要

应用同步辐射X射线荧光微探针技术（SRXRF）

观察稀土元素化合物硝酸镧La（NO3） 3（浓度为 10 - 8mol/L）对培养的单个大鼠平滑肌细胞内重要元素分布的影响

获得La（NO3） 3作用4h

2 4h时单个细胞内P

La等元素含量的相对计数。实验中观察到

10 - 8mol/LLa3+持续作用后

细胞内K

Zn等元素含量分布发生改变。结果表明

La3+可能富集在细胞内

影响细胞内某些重要元素含量的分布

可能是引起细胞生理生化变化的机制之一。

Abstract

By using Synchrotron radiation X-ray fluorescence (SRXRF) micro-probe

the relative levels of intracellular important elements (such as K

La) in single smooth muscle cell of rat under the actions of 10 -8 mol/L La(NO 3) 3 within 4h

8h and 24h

were detected respectively. The changes of intracellular important elements distribution in single smooth muscle cell were observed. The accumulation of La 3+ in cell

causing the change of intracellular important elements distribution

is one of the mechanisms of biological effect of rare earth element (REE) in cells.
