A total of 18 elements Se, Na, K, Br, Cl, Mn, Mg. S, Ca, Cu, Hg, Cr, Fe, Rb, Zn, Co, Sc and P has been determined for this purpose. The analytical results showed that compared with the normal brain tissues, concentrations of Ca, Fe, Cu, Zn, Mn, Br and Sc were significantly higher in tumour tissues and that of Rb, K and P were lower while no differences for contents of Mg, S, Cr, Na and Cl were observed. A negative correlation between P and Ca in malignant and normal brain tissues was observed.展开更多
