摘要: 为研究99m锝标记的D-二聚体(D-dimer,DD)单抗在静脉血栓和动脉血栓靶向定位诊断中的应用,采用外科手术的方法复制家兔股静脉和股动脉血栓模型,将99m锝标记的抗DD单抗注入动物血管内,以放射免疫显像检测技术观察放射性核素在血流和血栓部位的分布.结果:血栓形成术后2d,血栓处放射性99m锝的分布较健侧和正常兔明显增多,而单纯钳夹血管未能引起局部放射性物质的堆积.注射99m锝标记的单抗后,动物无明显不良反应,主要器官无明显病理学改变.研究结果提示:99m锝标记抗DD单抗可对实验性股静脉血栓和股动脉血栓作出快速、准确的定位诊断.

Abstract: The aim was to evaluate the precious localization of femoral venous and arterious thrombus targeted by 99mTc monoclonal antibody.Antibody labeled with 99mTc-anti-D-dimer was administrated into femoral vein and artery of the rabbits that were subjected to the thrombotic operation.Using radioimmunoimaging technique, the distribution, blood flow and radio-specificity of 99mTc-anti-D-dimer within thrombus were analyzed both in intact and thrombolized animals.Results: 99mTc-anti-D-dimer was specifically concentrated in thrombus, not in clamp and normal side.In addition, no abnormal reaction resulted from the injection of 99mTc-anti-D-dimer and no pathologic changes in main organs were found.Conclusion: the 99mTc-labeled anti-D-dimer antibody will be one of potentially tools for experimental thrombus diagnosis.

Key words: 99mTc labeled, anti-D-dimer antibody, thrombus
