磷酸钙

Modification of calcium phosphate cements using biodegradable microspheres proved to be an efficient drug delivery system allowing a broad range of 10–30% drug loading with uncompromised mechanical properties.

用生物可降解的中心体对磷酸钙粘固剂的修饰被证明是一个有效的药物递送系统，它可以扩大10–30%装载了强硬机械特性的药物的效应。

Histological studies showed that the osteogenic rate and quality in periostium- swathed samples were higher than that in the unswathed intramuscular samples.

基于上述研究，本文对骨诱导双相多孔磷酸钙陶瓷进一步作了骨内植入实验研究，探索其用于修复负重骨干缺损的可能性。

Rabbits (48 laterals) were prepared as model of bone defect, divided into 3 groups, named complex group (24 laterals), in which, unilateral bone defect of 24 rabbits were implanted with cell + carrier complex; The rtificial bone group (12 laterals), in which, CPAB was implanted contralaterally;and blank control (12 laterals), in which, no any management was done contralaterally in bone defect of 12 rabbits.

24只兔(48侧)制作成骨缺损模型，分为3组，复合物组(24侧)，24只兔一侧骨缺损植入细胞+载体复合物；人工骨组(12侧)，12只兔对侧植入磷酸钙人工骨；空白对照组(12侧)，12只兔对侧骨缺损不作任何处理。

Matsuyama et al used calcium phosphate cement, which polymerizes at lower temperatures.37,38 Results were good in terms of pain relief (8.6 preoperatively and 2 postoperatively on the visual analog scale), neurologic recovery and kyphosis restoration (vertebral height was restored to 68%, compared to 41% preoperatively).37,38 This combination of maximal/minimal surgical treatment has value especially in neurologically compromised patients with indication for surgery, who cannot tolerate long procedures and large blood loss due to medical comorbidities.

Matsuyama等人使用磷酸钙骨水泥，其硬化反应温度较低[37，38]，结果表明疼痛缓解良好（视觉模拟评分从术前的8.6分减至术后的2分），神经功能恢复和后凸畸形矫正良好（椎体高度从术前的41％恢复至术后的68 ％）[37，38]，这个&最大/最小&的手术组合治疗方法，尤其适合伴有神经症状而不能耐受长时间的手术和大量失血的患者。

This study examines a new surface treatment that uses coarse calcium phosphate, which provides the benefits of surface roughening without introducing any foreign materials that may become imbedded in the implants.

这一研究检测了一中使用粗磷酸钙进行新的表面处理的方法，它提供了表面粗糙的好处且没有引入任何外部的可埋置在种植体的材料。

Other Ingredients: dibasic calcium phosphate, silicified microcrystalline cellulose, stearic acid, modified cellulose gum, and colloidal silicon dioxide.

其他成份：双磷酸钙，矽化微晶纤维素，硬脂酸，改性纤维素胶，和胶体二氧化矽。

After preparing PC-HA and β-TCP by wet chemical precipitation method separately , granular type bone grafts were collected by filtrating, freeze drying, tableting, sintering, mixing, and size screening. All the bone graft specimens were analyzed with scanning electric microscope, Fourier transform infrared spectrometer and X-ray diffraction.

本实验室以湿式化学沈淀法分别反应生成PC-HA与β-TCP后，经过滤、混合、乾燥、压锭、烧结、粉碎后以不同网目筛网控制颗粒大小，备制磷酸钙骨移植材(PC-HA/β-TCP)，藉由扫描式电子显微镜、傅氏红外光谱仪与X光绕射分析仪进行材料之物化性分析。

MAIN OUTCOME MEASURES: The crystal structure of incorporated and untreated calcium acid phosphate bone cement was observed.

主要观察指标：①空白以及载药磷酸钙骨水泥微观结构的观察。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
