The concentration of some trace elements especially potassium calcium, manganese, copper and zinc in the arterial wall tissue for the aneurism patients was studied by PIXE (Proton Induced X-Ray Emission) analysis. Comparing the results with normal aortic wall tissues has been done. All the patients are in the age range of 40-60 years. The samples are derived from 15 patients by surgical operation. The results show the absence of manganese, and decreasing of potassium, Copper and Zinc in the aneurismal tissues. Change in copper concentration in the arterial wall is important in the breakdown of the elastic layer in the aneurism. Elevation of the Calcium and Iron in the aneurism tissues are obtained in the comparison with the control groups. Deficiency or elevation of some elements in the aneurism aorta can be encountered as an indicator in the biopsy analysis. [ABSTRACT FROM AUTHOR] |
