| Background: Proton induced X-ray emission
(PIXE) has been applied as reliable and improved
techniques in this study to compare concentration of
various trace elements in normal and abnormal
varicose veins. Materials and Methods: Five samples
from normal veins and 13 samples from varicose
veins bombarded by 2.0 MeV energy proton beams
produced by a Van de Graff accelerator in vacuum.
Two specimens from each sample, approximately
1cm, were processed for PIXE (proton induced X-ray
emission) analysis. Both qualitative and quantitative
analyses of potassium, iron, copper and zinc
concentration were performed with respect to
calcium concentration. Results: The concentration of
potassium and iron in the varicose vein group has
been significantly higher than the normal group.
Copper and zinc concentration were also higher in the
varicose veins, and the elevation of bromine was
seen in the normal group. Conclusion: PIXE analysis
showed higher concentrations of trace elements in
veins derived from varicos patients compared to
normal group. The difference in normal and abnormal
vein might be independent of age. Iran. J. Radiat. Res.,
