title: [State of vascular regulation and regional hemodynamics in the crew of "Soiuz-12" and "Soiuz-13" spaceships before and after flight].
abstract: Postflight rheographic examinations carried out at rest and during postural tests showed noticeable changes in the vascular regulation and significant blood redistribution. On the recovery day there were no signs of the intracranical venous congestion to weightlessness. The tone of cerebral vessels, however, increased to prevent the development of cerebral venous congestions during the antiorthostatic test. This may be a result of weightlessness adaptation. These cerebral hemodynamic reactions were more pronounced in the crewmembers who made an 8-day flight than in those who made a two-day flight, i. e. in the cosmonauts who returned to Earth after weightlessness adaptation.
