Hemostasis system indices in the course of a 105-day hermetic chamber isolation experiment

Abstract

The present paper deals with studying of hemostasis system indices in the course of the experiment with a 105-day isolation in a hermo chamber. The following values were determined: activated partial thromboplastin time, prothrombin time (PT), prothrombin index (PI), international normalized ratio [relationship] (INR), thrombin time, fibrinogen concentration, soluble fibrin-monomer complexes, D-dimer, plasminogen (PG), activity of antithrombin III, protein C, alpha2-antiplasmin. According to the experiment results, isolation is accompanied by PT prolongation (PI decreasing, INR increasing) which conserves up to the 7th day of the aftereffect period, as well as by PG concentration decreasing. Changes are likely to be connected with peculiarities of reduced motion activity conditions, compensatory physical activity influence, protein and lipid metabolism characteristics changing.
