[Effect of the C1q complement subcomponent on blood coagulability and fibrinolysis]

The in vitro experiments on human plasma have shown that C1q addition in a concentration of 120 micrograms/ml led to a substantial shortening of coagulation time of test-plasma, as well as kaolin- and cephalin time. The effect is preserved in plasma deficient in factors V, X and VII. It is assumed that C1q has properties similar to those of thromboplastin.
