The inhibitory effect of heparin on trypsinogen activation with enterokinase.

The effect of heparin on the activation of trypsinogen by enterokinase and on trypsin activity has been investigated. Proteolytic activity of trypsin has been determined using caseinolytic method. It has been found that heparin inhibits trypsinogen activation only when it is preincubated with proenzyme before introduction of enterokinase to the tested system. In these experimental conditions heparin in final concentrations from 1 to 20 U/ml exhibits inhibitory effect diminishing trypsinogen activation to about 65% initial activity and in higher concentrations only to 50%. Heparin introduced to the tested system simultaneously with enterokinase or to the active trypsin did not appear evident inhibitory effect.

Peripheral and gastric fibrinolysis in patients with gastric carcinoma.

The fibrinolytic system was studied in blood-samples from gastric and peripheral veins of patients with gastric carcinoma. There was a slight decrease in plasma-euglobulin fibrinolytic activity, a rise of plasma-fibrinogen level and antithrombin VI activity, and a decrease in antiplasmin activity. The changes observed are more marked in blood-samples from gastric veins. Some therapeutical implications and the role of fibrinolytic agents in malignant diseases are briefly discussed.
