Cytocompatibility Evaluation of Materials From Cellulose

Based on the GB standards of cytocompatibility evalution tests for medical materials,this study evaluates the cytocompatibility of materials synthesized from cellulose.The cytotoxicity of the materials from cellouse was evaluated by the method of cell relative growth rate of L-929 mouse fibroblast cultured in the medium of extraction of the material from cellouse.The cytotoxicity test showed that the cytotoxicity graduation of the materials from cellouse is 1 or 0,and showed nearly no cytotoxicity.Hemolysis test were conducted by the method of indirect contact and its results showed that the materials from cellouse has no obvious hemolysis reaction,the hemolysis rate in vitro was 1.5%.
