RESUMO
Hypercoagulation and fibrinolysis inhibition are seen in adult rats 6 to 6 1/2 months after thymectomy. Hemocuagulation accelerating is caused by the shortened 1st phase of the blood coagulation process. Fibrinolysis delay is partially produced by a decrease in the fibrinalytic agent concentration and smooth elevation of the antiplasmin level. The most part of the coagulogram indices and fibrinolysis activation returns to normal in operated animals following the injection of a low-molecular polypeptide thymic factor within 5 days.

The amount of procoagulative and fibrinolytic agents in cellular organoids was studied in the cat n. ischiadicus. All cellular fractions revealed high thromboplastic activity. Plasminogen, its activator, and proactivator were discovered in the ischiadic nerve. In dogs, the changes of functional state of nerves were accompanied by discharging of tissue thromboplastin and stimulators of fibrinolysis into the external medium with stimulaneous changes of intracellular contents of hemocoagulating factors. Thus, electric stimulation of the nerve intensified its thromboplastic activity, increased concentration of analogs of the plasma factors (II, VII, IX) and stimulation of fibrinolytic agents. The data obtained suggest presence of close enough interaction between the changes of functional condition of cells and dynamics of their procoagulative and fibrinolytic power.
