三种癌的铬、锰、锌、铜、铁、镁、钙含量

The Contents of Cr, Mn, Zn, Fe, Cu,Mg and Ca in Three Type Cancer

为进一步阐明癌组织与宏量、微量元素的关系，用原子吸收光谱法测定胃癌、大肠癌、乳腺癌组织及其癌旁组织和同体正常组织中铬、锰、锌、铁、镁、铜和钙的含量，试找这些元素在癌、癌旁及其同体正常组织中的分布规律．测定结果：在胃癌组织中锌的含量比癌旁组织、同体正常组织少，铜的含量比正常组织多，其余五种元素的含量在这三个组织之间比较无明显差异；在大肠癌组织中锰、镁的含量比癌旁组织多，其他五种元素的含量在这三个组织之间比较，无明显差异；在乳腺癌组织中铬、锰和铁的含量比正常组织多，锌、镁、钙的含量比同体正常组织和癌变组织多，铜的含量在这三个组织中比较无明显差异．总之，胃癌、大肠癌及乳腺癌组织及其癌旁组织和同体正常组织中，上述七种元素的含量是不同的，特别是在乳腺癌组织中除铜以外的六种元素的含量都比正常组织多，值得进一步研究．

To further expound the relation between the cancer tissue and macro. trace elements, and try to find out the distribution of trace elements in the carcinoma of stomach. large intestine, breast and its peripheral and normal tissue. the levels of Cr, Mn, Zn. Fe. Mg. Cu and Ca in these tissuese were measured by atomic absorption spectrometer.The results indicate that the Zn level is lower stomach cancer than its peripheral and normal tissue and Cu level is higher than its normal tissue, but the levels of the other five elements in these three tissues are no significant difference. The levels of Mn and Mg are higher in large intesinal cancer than its peripheral tissue. but there are no significant differences in the levels of other five elements. The levels of Cr, Mg and Fe are higher in breast cancer than its normal tissue, and the levels of Zn, Mg and Ca are higher than its peripheral and normal tissue with Cu exception.In short, there are different levels of above seven trace elements in the carcinoma of stomach, large intiestine, breast and its peripheral and normal tissue, expecially the levels of 6 elements with Cu exception are higher in breast cancer than its normal tissue. It is necssary to further study.
