[Procoagulant and fibrinolytic activity of fractions of a rat brain homogenate].

In all subcellular fractions the rat's brain homogenate active thromboplastin, activators and inhibitors of fibrinolysis were detected. Nuclear fraction contains factors II, VII, X, XIII. The mitochondrial fraction-factors II and VII, and postlysosomal supernatant demonstrated the presence of factor V of blood coagulation. The results obtained are of importance for the explanation of control mechanisms of blood coagulation and fibrinolysis.
