  • Title: Amino acid spectrum of human blood plasma during space flight and in antiorthostatic hypokinesia.
    Author: Ushakov AS, Vlasova TF.
    Journal: Life Sci Space Res; 1976; 14():257-62. PubMed ID: 11977280.
    Abstract:
    The paper summarizes results of experiments on the influence of space flight and anti-orthostatic hypokinesia on the amino acids spectrum of human blood plasma. Our findings give evidence for: (i) A specific norm of the content of free amino acids in plasma during training and (ii) consistent changes of plasma aminograms during space flight related to its duration and to individual features of cosmonauts. The content of free amino acids in the plasma of bed-rested subjects varied phasically and tended to increase practically at every experimental stage. The paper discusses the findings and possible mechanisms of the detected changes.
