Abstract
The aim of our experiments was to investigate the possible elemental concentration changes in brain tumours (glioblastoma multiforme). Our project also incorporated the determination of the regional distribution of elements in normal human brains. 17 elements (Na, K, Ca, Mg, Fe, P, S, Al, B, Ba, Co, Cr, Ni, Mn, Pb, Sr, Zn) have been measured in 21 different regions of 20 normal brains and in clinically and histopathologically selected brain regions of patients with brain tumours. Analyses were carried out by instrumental neutron activation analysis (INAA) and inductively coupled plasma atomic emission spectrometry (ICP-AES). Quality control was ensured by using NBS Bovine Liver 1577a standard reference material. Comparison between the healthy and brain tumour concentration data using statistical evaluation revealed only a few elements (e.g. B, Zn, Sr) which showed significant differences as a consequence of the brain tumour.
