title: [Effect of thyrotropin-releasing hormone and its synthetic analogue digipramine on certain hemostatic indices in vitro and in vivo].
abstract: The effect of neuropeptide thyrotropin-releasing hormone (TRH) and its synthetic analogue digipramine on certain indices of the blood coagulation system and fibrinolysis were studied in vitro and in vivo. The peptides added to the pool of normal rat plasma at 10(-10) to 10(-3) M increased the procoagulant activity but had virtually no effect on fibrinolysis. Intravenous administration of TRH and digipramine increased the procoagulant activity of the blood and thrombocyte aggregation but decreased fibrinolysis; digipramine had a more pronounced effect on the coagulation potential of the blood and a less pronounced effect on fibrinolytic indices as compared to TRH. Intranasal administration of the peptides did not change the pattern of their effect on hemostatic indices although the effects became less pronounced.
