[Fibrinolytic activity of heart tissues and aorta of rats undergoing electroshock]

In the first minute of shock caused by electric current passing through the rats parietal lobe the increase of fibrinolytic activity of euglobulin fraction of blood occurs. During the investigation of the right heart ventriculus tissue and aorta by histochemical method of Todd in our modification the decrease of fibrinolytic activity in wall of aorta (on 80%) and in tissue of heart ventriculus (on 30%) has been revealed in tentative animals as compared with control ones. It is suggested that the entering of plasminogen activator from vessel wall into the blood flow plays an important role in activation of fibrinolytic system in generalized reaction of organism to strong stress action.
