Objective To investigate the blood compatibility of silk fibroin membrane.Methods Recalcification test, hemolysis test and platelet adhesive test were conducted for compact silk membrane, polyporous silk membrane, bovine pericardium and collagen sponge. Results Recalcification time of compact silk membrane is longer than that of other three materials. The homolysis rate of compact silk membrane, polyporous silk membrane, bovine pericardium and collagen sponge was 3 28%, 2 02%, 0 19%, 0 28% respectively. The homolysis rate of all materials was less than 5%. It shows that the four materials did not lead to hemolysis. Platelet adhesive test shows that the surface of compact silk membrane had less platelet than that of other three materials. The platelets on surface of all four materials were without obvious malformations.Conclusion The silk membrane suggests good blood compatibility, and the compact silk membrane has anticoagulant effect.
