title: [Effects of microgravity on indices of hemodynamics in monkeys during postural tests].
abstract: Effects of the 6-day flight on board Cosmos 1667 on the dynamics of arterial pressure (AP) and the linear velocity of blood flow in the common carotid artery were studied with modified postural tests in the experiment with Macaca mulatta No. 18933. Initially, the postural test procedure and the method of mitigating the psychoemotional stress due to transition of the tilt-table were tried out on 21 primates. Administration of the functional test in microgravity was found to exert both qualitative and quantitative effects. The last mentioned were registered only in the primates tilted downward and included lowered AP vs. elevated AP in the control, and absence of typical bradycardia.
