title: [Effect of hypokinesia and +Gz loads on the transport function of blood in man].
abstract: The results of 44 studies of circulation parameters and blood transport function of 14 test subjects exposed to 7-day bed rest (-10 degrees head-down tilt) and acceleration -4.5 Gz have demonstrated that the blood transport carriers and their actively binding centers form working structures in the adaptive reactions. As compared to the pretest level, the distribution ratio of 14C-adenine between two immiscible phases (plasma/oil, erythrocytes/oil) varies from -12 to 14% on bed rest day 3 to +32 to 40% on bed rest day 7; it increases by 145-150% after exposure to acceleration +4.5 Gz. The parameters of the blood transport function give a quantitative description of its adaptive reactions to environmental effects.
