摘要

我们已经开发出磷酸钙水泥(CPC)，它可以在手术过程中形成任何所需的形状。新型羟基磷灰石(HAp)和磷酸三钙(TCP)胶结物是基于磷酸肌醇(IP6)的螯合能力而形成的。在本研究中，我们在pH5.5的醋酸缓冲溶液中测定了各种CPCs的溶出率。用钙离子计连续测定醋酸缓冲液中HAp、-TCP和-TCP相cpc释放的钙离子浓度。湿法制得的样品溶解速率依次为-TCP >-TCP > HAp

IN VITRO BIORESORBABILITY OF CHELATE-SETTING CEMENTS WITH VARIOUS CALCIUM-PHOSPHATE PHASES

: We have developed calcium-phosphate cement (CPC) that can be formed into any desired shapes during an operation. The novel hydroxyapatite (HAp) and tricalcium phosphate (TCP) cements set on the basis of chelate-bonding ability of inositol phosphate (IP6). In the present study, we evaluated dissolution rate of various CPCs under conditions of acetic acid buffer solution at pH5.5. The concentration of calcium ions released from the CPCs with HAp,  -TCP and  -TCP phases in the acetic acid buffer solution was continuously measured using a calcium ion meter. The dissolution rate of samples decreased in order of  -TCP >  -TCP > HAp derived from wet process
