乙酸

A porous lanthanum-doped hydroxyapatite coating on commercially pure titanium was prepared by micro-arc oxidation in electrolytic solution containing calcium acetate,β-glycerol phosphate disodium salt pentahydrate and lanthanum nitrate.

采用微弧氧化法在含有乙酸钙、β-甘油磷酸钙、硝酸镧的电解液中在纯钛金属表面原位生成了多孔含La羟基磷灰石的生物涂层。

The mechanism was supposed as follows: polyfluoroalkyl iodides were initiated by sodium dithionite to give R〓 which was added to one double bond of diallylacetic acid, after the sequential radical cyclization and nucleophilic substitution to form bicyclo-lactones.

这是因为：多氟烷基碘化物在连二亚硫酸钠的引发下，得到自由基R〓，后者加成到二烯丙基乙酸中的一个—C=C—双键上，然后在碱性介质中进行分子内亲核反应得到双环内酯类产物。

In this report, the 59Tc labelling of Annexin V fragment modified with HYNIC (HYNIC-Anx13) using Tricine, EDDA or EDDA/Tricine as coligands was described. The effect of various factors on 99Tc labelling was investigated. Biodistribution studies in normal mice and gamma imaging of apoptosis in rats induced by cyclophosphamide were performed.

为探讨99Tc标记的HYNIC-Anx13用于细胞凋亡显像的可能性，分别以N-［三甲基］甘氨酸，乙二胺－N，N'-二乙酸和EDDA/Tricine为协同配体，对经6-肼基烟酰基修饰的膜联蛋白V片段(HYNIC-Anx13)的99Tc标记条件和主要影响因素进行了研究，并完成了HYNIC-Anx13的99Tc标记物在正常小鼠体内的生物分布和大鼠细胞凋亡模型的显像实验。

Methods: TOCA was labeled with (superscript 99m)Tc using HYNIC as bifunctional chelator, EDDA and trieine as coligand. The nude mice bearing human small cell lung cancer underwent static whole body planar imaging after the injection of (superscript 99m)Tc-HYNIC-TOCA or (superscript 99m)Tc-P829. ROIs were drawn and the radioactivity ratios of target to non-target were calculated in every planar imaging. The dynamic biodistribution study was operated in Kunming mice and the percent uptake ratios of two imaging agents in different tissue at different time were measured.

以HYNIC为双功能螯合剂(bifunctional chelator， BFC)，乙二胺－N，N'-二乙酸和三甲基甘氨酸为协同配体进行TO-CA的(上标 99m)Tc标记；以(上标 99m)Tc-HYNIC-TOCA和(上标 99m)Tc-P829为显像剂，对荷人类小细胞肺癌裸鼠进行显像，通过感兴趣区技术进行半定量分析，计算并比较两种显像剂的靶/非靶比值；在昆明鼠体内进行动态生物学分布实验，测定并比较不同时点两种显像剂在各脏器的克组织百分摄取率。
