Turbidimetry studies showed that after addition of thrombin to fresh donor plasma light scatter in the sample increases and slowly attains a plateau. The process of fibrin formation was less intensive in the presence of oxidized fibrinogen. The formation of fibrin clot in lyophilized plasma was characterized by a biphasic kinetic of light scatter, oxidized fibrinogen inhibited both phases of the process. In the presence of streptokinase, oxidized fibrinogen did not modify the kinetics of fibrin clot lysis. Addition of oxidized fibrinogen to plasma reduced optical density of fibrin clot the more intensely the higher was the degree of oxidative modification of fibrinogen.
