Abstract:

BACKGROUND: Experts believe that the improvement of hemocompatibility of the anticoagulant biomaterials can significantly improve the anticoagulant properties of the anticoagulant biomaterials.
OBJECTIVE: To evaluate the hemocompatibility of the polyester-based and titanium-based anticoagulant biomaterials.
METHODS: The effect of polyester-based and titanium-based anticoagulant biomaterials on the level of red blood cells, platelets, albumin, fibrin and coagulation factors was explored through searching the relative literatures. The anticoagulant properties of the polyester-based and titanium-based anticoagulant biomaterials were analyzed through the hemolysis test, dynamic blood coagulation test, platelet adhesion test, serum protein adsorption experiment recalcification test and lactate dehydrogenase releasing test, thus the hemocompatibility of the polyester-based and titanium-based anticoagulant biomaterials was evaluated.
RESULTS AND CONCLUSION: The hemolysis rate of polyester-based and titanium-based anticoagulant biomaterials was significantly decreased, and the polyester-based and titanium-based anticoagulant biomaterials have less platelet adhesion and increased adsorption amount of albumin, and the fibrinogen adsorption was significantly reduced, the recalcification time and clotting time was significantly prolonged. The polyester-based and titanium-based anticoagulant biomaterials show a higher anti-clotting property, which are ideal anticoagulant biomaterials.
