[The effect of head-down tilt bed rest on metabolism of erythrocytes and functional state of membranes in females].

: Metabolism of erythrocytes and the structural/functional state of membranes were studied in females in the 120-day head-down bed rest and the subsequent period of recovery. As was stated, prolonged bed rest and early recovery cause shifts in the metabolic and structural parameters of erythrocytes and ensuing degradation of the functional state of erythrocytes, i.e. changes in deformability and echinocytosis. The system of countermeasures including exercise and a set of alimentary supplements with polysaturated fat acids and antioxidants, proved to moderate the changes although it failed to fully eliminate them.
