[Fibrinolytic and fibrin-stabilizing properties of human tissues].
Fibrinolytic and fibrinase properties of the most of human organs and tissues have been studied. It has been established that fibrinolytic activity of the tissues highly varied. Fibrinolytic agents of the tissues are rather unstable to dilution, in contrast to thromboplastin, that is stable to dilutions as 1:10000 and 1:100000 and higher. All the tissues contain both activators and inhibitors of fibrinolysis. In some of them inhibitors prevail, that proves their antifibrinolytic properties. Tissue fibrinase decreasing fibrinolysis effectiveness, is detected almost in all tissues. The experiments with intravenous injection of extracts from different tissues have demonstrated that regardless of their fibrinolytic activity, the course of hemostasis impairment is of the same type: at the moment of the extract injection fibrinolysis is sharply inhibited, and then intravasal blood coagulation develops under the influence of strong tissue thromboplastin; the phase of hypercoagulemia is changed by that of hypocoagulemia attended by a secondary increase of fibrinolysis. The author believes that when "juices" of different tissues enter the blood flow the impairment of blood coagulation, by the mechanism of thrombohemorrhage syndrome (THS) takes place, and fibrinolysis is secondary-activated and represents a reaction of the second phase of THS.
