[Element analysis of sclerotic plaques of large blood vessels by laser mass-spectrometry].
Laser mass-spectroscopic studies were carried out of element and isotope composition of sclerotic formations (patches) of large blood vessels on calcinosis and ateromatosis stage, as well as of the region adjoining the calcinosic formation of the vessel tissue. It was shown that the basis of the "patches" consists of carbon, nitrogen and oxygen. 13 elements of micromixtures were found. Changes were revealed of the content of some elements and anomalous disturbance of natural distribution of oxygen, silicon, magnesium and calcium isotopes depending on the stage of arteriosclerosis formation.
