【摘要】 将超离心分离技术与中子活化分析法相结合,分析测定了正常人肝亚细胞组分中的微量元素。介绍了样品的采集制备、微量元素的实验测定,使用标准参考物质NBS-1577a,IAEA-H8校对了方法的可靠性。报道了人肝5种亚细胞组分(核、线粒体、溶酶体、微粒体、胞液)中8种微量元素的含量,并对其分布进行了初步研究。更多还原

【Abstract】 The concentration of 8 elements in subcellular fractions of normal human liver has been determined by a combination of differential centrifugation and neutron activation analysis. The collection of samples and the determination of trace elements were described in detail. Two biological standard reference materials were used for evaluating accuracy of the INAA method. Trace element contents and their distribution in 5 subcellular fractions of human liver have been investigated.更多还原
