[Connection of the carbon isotopic composition of human hair with its functional state]
Abstract:
Temporal variations of carbon isotope composition of hair taken from faces of three men with different health state were studied. Drastic enrichment (up to 20%) of hair carbon in heavy isotope, as compared to the basic line reflecting background isotope variations was discovered in one of the men under test. This enrichment correlated with his worsened state of health. Then carbon isotope composition of hair returned to the background level. Probable explanation of this correlation was suggested in terms of earlier described mechanism of carbon isotope fractionation in a living cell.
