通过对Oswestry骨、Kiel骨、乙醇、乙醚四种方法制备的牛脱蛋白骨(bDPB)的氨基酸成份分析间接推断其机械性能及抗原性差异。结果表明,四种方法制备的抗原性都低,而其中用20％H_2O_2脱蛋白,乙醚脱脂24h方法制备的bDPB芳香族氨基酸含量最低,而胶原类氨基酸含量最高,因而具有抗原性低,机械强度好的特点,加之来源广泛,制作简单,作为骨移植的材料或BMP的载体有较强的临床应用价值。 The mechanical properties and antigenic differences were indirectly deduced by analyzing the amino acid composition of bovine deproteinized bovine (bDPB) prepared from Oswestry bone, Kiel bone, ethanol and ether. The results showed that the antigenicity of all the four methods was low, but the content of bDPB aromatic amino acid prepared by 20% H 2 O 2 deproteinization and ether degreasing was the lowest, while the content of collagen amino acids was the highest, so the antigenicity was low, the mechanical strength Good features, combined with a wide range of sources, production simple, as a bone graft material or BMP carrier has strong clinical value.
