Mineral trace element concentration of human saliva from healthy volunteers, were investigated by Proton-Induced X-ray Emission (PIXE) analysis. The specimens were bombarded with Proton beams of 2 MeV from a Van de Graaff accelerator at NRC . The object of this measurement was to find a normal range of trace element concentration for Iranian people.
Proton Induced X-ray Emission analysis was applied to measure the concentration of Fe, Cu and Zn in liver biopsy samples with Wilson’s disease. Due to the small size of sample and non-conductive character of the material absolute measurement was not possible, therefore the ratio of elements such as Cu/Fe and Zn/Fe were determined. The comparison of these values obtained from normal liver samples helps the physicians to determine the stage of disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
