[Mechanism of fibrin formation in the tissues in gastric adenocarcinoma]

The investigation of extracts from intact and tumour tissues of the human stomach has revealed that adenocarcinoma tissues possess abnormal antiheparin, antithromboplastin and fibrin-stabilizing activity. Heparin activity, as well as the level of antithrombin III and fibrinogen-heparin complex were sharply reduced. The accumulation of anti-heparin compounds normalizing heparin and displacing the coagulating albumin from the complex with anticoagulant is believed to be one of the most important factors of fibrin production in the tumour.
