[Features of hemostasis and thrombocyte function in the yellow suslik]

High levels of blood-coagulating factors and of antithrombin III low plasma tolerance of heparin, high velocity of Hageman-dependent processes of prothrombinase formation and plasminogen activation were found in yellow suslik. The level of hemostasis processes in hibernating animals is related to change of their functional state during an intense ontogenetic development and adequate to their physiological activity in seasonal cycle.
