title: [The antithrombotic action of a protein C activator from the venom of Agkistrodon blomhoffi ussuriensis in thrombus formation in an extracorporeal shunt in rats].
abstract: An antithrombotic action of the protein C (PC) activator from the venom of Agkistrodon blomhoffi ussuriensis on the model of platelet-dependent thrombosis in the arteriovenous shunt in rats was under investigation. Administration of the PC activator to rats resulted in a dose-dependent prolongation of the thrombus formation time, in a decrease in PC and factor V levels in blood and in APTT prolongation. There were no changes in the tissue-type plasminogen activator level and in the ADP- or epinephrine-induced platelet aggregation, but platelet adhesion to glass decreased. The possible mechanism of the antithrombotic action of the PC activator appeared to be the factor V inactivation mediated by protein C activation and the decrease in platelet adhesion.
