Distinct decrease in fibrinolytic activity of both whole blood plasma and its euglobulin fraction, occurring due to liberation of an inhibitor of plasminogen activator into circulation, was observed within 2-4 hrs after a single intravenous administration of rabbit interleukin-I into rats at a dose of 50 micrograms/kg, while the activator activity was increased in kidney heart, spleen and lung tissues. The similar data were obtained if the dose was either increased up to 150 micrograms/kg or decreased down to 5 micrograms/kg and 0.5 micrograms/kg, but the effect observed proved to be dose-dependent. Three injections of interleukin-I caused more pronounced increase in concentration of fibrinogen and antiplasmins as compared with controls.
