title: [Evaluation of effectiveness of short-term orthostatic positioning of head-down tilted primates on the liquid body sectors].
abstract: Head-down tilting (HDT) of primates is a well-recognized model for studying the hypokinetic syndrome effects on the body functions. Benefits for the body liquids distribution of periodic transition of primates (rhesus macaques) into the vertical position without support loading were evaluated in a 30-d HDT experiment. Brief (30 to 120 minutes long, 4-5 times a week) transition from tilting into the vertical position had no influence on primates' hydration homeostasis and its infrastructure. However, the orthostatic test at the end of the HDT experiment showed a less increase in blood content of the lower extremities as compared with tilted primates that had not been periodically turned up into the vertical position.
