[Effect of vasopressin and its analogs on blood coagulation in rats].
A change in the response of the blood coagulation system to the intravenous injection of vasopressin (AVP), DDAVP and DGAVP has been studied in the experiments on white rats. Intensification of the procoagulant activity on AVP is of the dose-dependent character. Maximal effect is observed 5-15 min after i.v. injection of AVP in a dose of 4 mg/kg. The administration of this peptide increases the fibrinolytic activity, that is connected with an increase in the level of plasminogen activator. DDAVP and DGAVP have a weaker effect on fibrinolysis. AVP and DDAVP increase the level of FVIII by 5-6% during the first minutes, but DGAVP increases the level of FVIII only after 15-30 minutes. While using AVP, DDAVP and DGAVP in clinical practice it is necessary to allow for their hormonal action, the initial state of haemostasis and the age of patients.
