title: [Detection of silicon in a human spleen using x-ray microanalysis].
abstract: There is a lack of information on x-ray microanalysis (XMA) of the human spleen. We have examined the spleen of a patient with autoimmune thrombocytopenic purpura. The specimens were fixed in glutaraldehyde and coated by copper. The XMA was performed by a Quantum detector and a Delta-Class analyzer. In addition to spectral lines of elements normally present in human tissues, we have demonstrated silicon. The presence of silicon in human spleen may be a consequence of the organ's cleansing function.
