Abstract
The activity of cancer procoagulant (CP) during the development of GuΓ©rin epithelioma was studied in the blood of Wistar rats. Blood was collected from the carotid artery and, after clotting, proteins adsorbing on aluminum hydroxide were removed from the serum. Then procoagulant activity was determined in the test system without factor VII by means of substrate Sβ2222 specific for factor Xa. A statistically significant increase in the activity of CP in serum was detected, coinciding with the period of intensive tumor growth (15thβ25th day of disease).
