[Body fluids ratio and postural stability of head-down tilted apes in the periods of transition into the active vertical position].
It is known that the hypokinetic syndrome and alteration of the hydrostatic component by microgravity distort functioning of various body systems. Prevention of the adverse effects is achieved through implementation of a variety of physical exercises during tilting, and periodic transition into the upright position. The investigation was performed with 11 Macaques (Macaca mulatta) 3 to 5 yrs. of age and 3.2-7.2 kg of weight. Brief (for 30 to 120 min 4 or 5 times a wk.) transition into the active upright position had a positive effect on the body liquids ratio modification in the course of 27-d HDT (-5 degrees). This was concluded from a less pronounced loss in the amount of extracellular liquid and its interstitial component. In addition, another positive result of this manipulation was less, in terms of volume and speed, significant gravity-dependent blood flow toward the lower limbs during 10 minutes of standing test at the end of the experiment as compared with their controls w/o the preventive manipulation.
