摘要 目的采用超声辅助酶法去抗原处理异种骨,期望获得具有免疫原性低、具有良好生物力学性能的理想骨移植材料。方法将猪异种骨用超临界CO2脱脂、深低温冷冻处理后分为3组,分别采用超声波辅助胰蛋白酶法去抗原(A组)、单纯采用超声波法(B组)或胰蛋白酶法(C组)处理异种骨,并取新鲜骨为D组。观察和比较各组的骨材料大体标本和切片、抗原性、材料的生物力学特性。结果超声辅助酶法去抗原处理异种骨速度快,经处理后的猪异种骨材料去抗原更彻底,免疫原性低,孔隙率最高,孔径大小最佳,但材料的生物力学性能有明显下降。结论超声辅助酶法是一种较好的骨材料去抗原处理方法,但处理完后对材料的生物力学性能有明显影响,还需要进一步优化实验参数。
