[Computer modeling of ESR spectra of the plasma in patients with Down's syndrome].

ESR technique at 77 degrees K was used for studying the blood plasma ESR signals of patients with Down syndrome and of healthy people. It was observed that the first exhibited a tendency towards a decrease of ESR signal with g = 4.3 and increase of the ratio of ceruplasmin (g = 2.05) and transferrin (g = 4.3) ESR signal amplitude. A computer simulation has been carried out by means of special mathematical program of experimental ESR spectra of the blood plasma.
