Abstract
Hemostasis has been studied in the course of long-term (520 days) isolation in hermetic chamber. Measured parameters included activated partial thromboplastin time (APTT), international normalized ratio (INR), thrombin time (ТT); concentrations of fibrinogen (FBG), plasminogen (PG), Willebrand factor (WF), tissue factor pathway inhibitor (TFPI), tissue plasminogen activator (TPA), and thrombomodulin (ТМ); activities of the coagulation cascade factors II, V, VII, X, VIII, IX, XI, and XII, antithrombin III (ATIII), protein С (PC), С1-inhibitor (С1), α2-antiplasmin (АP), TPA and TFPI. The investigation revealed a diversity of changes in plasma FBG concentration, slower blood coagulation in the intrinsic pathway and in final stage, and a relative rise in the activities of ATIII and PC-inhibited factors. The remaining parameters exhibited different trends.
