Diveropment of alpha-TCP/DCPD Bioactive Bone Cement

1.α-磷酸三钙/双环戊二烯的组成比及强度在α-磷酸三钙中加入10%双环戊二烯、骨水泥粉液比时，骨水泥的强度最大。混合三天后。最大强度出现在57 Mpa，胶凝材料逐渐趋于稳定。粘固剂的粘度该粘固剂可用于人工关节的固定或骨缺损的填充材料。由于这些用途，水泥应保持适当的粘度，以便于处理。粘度：将取决于粉末和液体的含量。得出DCPD中加入10%的水泥与2倍量的液体混合最为合适。活体兔股骨髓内管自远端至近端2 cm长的钻孔。然后将水泥浆通过管道注入。在0.5年和1年后，我们制备了一些骨组织标本。并观察其病程变化。但是，在骨组织界面上没有观察到任何信息。

1. The ratio of compositions alpha -TCP/DCPD and the strengthThe maximum strength of bone cement was obtained at the alpha -TCP added 10% DCPD and the ratio of bone cement powder and solution. Three days after mixing. the maximum strength of 57MPa was appeared and the cement was weekend gradually.2. The Viscosity of cement pasteThis cement will be used for the perpase of fixation of artificial joint or filling material of bone defect. Due to these uses, the cement should liave suitable viscosity for easy treatment. The viscosity : will be governed with the contents of powder and liquid. Then we are ovser ved that 10% of DCPD added cement mixed with two times much of liquid was most suitable.3. Biocompatibility test for the bone cementIntramedulary canal of femur of living rabbit was drilled from the distal end to 2 cm length proximal direction. And then the cement paste Was injected through the canal. After 0.5 and I years, we preparated some bone tissue samples. of the rabbits and observed the histrogy. But, no information was observed at the interface of bone tissue.
