[Physiologic properties of heparin--thromboplastin complex].

The complexes of heparin with components of tissue thromboplastine occurring in vivo and in vitro, reveal an anticoagulating and antipolymerizational effects as well as a nonfermentative fibrinolytic activity. The latter becomes obvious in presence of proteinase inhibitors. On i. v. administration, the complex increases the fibrinolytic and anticoagulating properties of the blood. Its nonfermentative fibrinolytic activity in the bloodstream lasts for 60--90 min.
