The 7000 bp DNA/protamine complex had a negative charge while the original DNA/protamine complex had a positive charge. The cell viabilities (90.4-106.8%) of these complexes were close to each other. The 7000 bp DNA/protamine complex became a softer dough than that of the original DNA/complex when both were kneaded with water. In vivo, the original DNA/protamine complex showed a milder tissue response. The original DNA/protamine complex almost disappeared 30 days after implantation. The 7000 bp DNA/complex disappeared approximately 2 weeks after implantation and areas where samples were implanted became empty. Thereafter, the empty space was gradually replaced by new soft tissues. The original DNA/protamine complex showed low intercalation and groove binding ratios of daunorubicin hydrochloride. Results indicate that high DNA condensation by cationic protamine protected the penetration of degradation enzymes into these complexes. It was found that a high molecular weight of DNA reduced the biodegradation rate and flowability. This study suggests that DNA/protamine complexes could be candidates for biomaterials that control biodegradation rates and flowability.","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"報告番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第244号"}]},"item_10006_relation_14":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"J Biomed Mater Res B Appl Biomater. 2013 Jul;101(5):743-51. doi: 10.1002/jbm.b.32877.
