Biomedical Application of PIXE. Studies of Track Elements in Human Hair, in Control and Hyperactive Children.

摘要

Hair samples from hyperactive and control children have been analyzed for their trace elemental contents by PIXE. The main elements examined are S, K, Ca, Fe, Co, Ni, Cu, Zn, Se, Br, Hg and Pb. The significant difference between the elements in control population and in patients suffering from pathological conditions are examined. Investigations of the possible linear and multiple correlations between elements in each population are made. The work indicates that some elements do exhibit variation with pathological state.
