Abstract： |
The invention relates to a biological tissue material and its preparation, in particular to a calcium phosphor salt base bone repairing material and its preparation. Said material provided by the invention contains calcium phosphor salt and chitin/chitosan fiber, which existes in form of fiber thread or fiber bunch. It can also be combined with 0.1-10% chitin derivants like chitosan, phosphorylate chitin, phosphorylate chitosan, carboxylation sulation chitosan and or 0.01-0.1% collagen, bone formation protein amethopterin or adriacin. Cell experiments and animal experiments all indicate that the material has favorable biological compatibility and induction activity for osteogenesis. It can raise averagely 1 to 10 times of flexural resistant intensity of calcium phosphor base bone repairing material. The invention is a reliable in vivo degradable material for tissue repairing and treatment. |
