摘    要:对磁性明胶微球进行了同位素标记。用γ-闪烁照相技术观察了磁性明胶微球在兔体内的分布。结果表明:靶部位的放射活性加磁场是未加磁场的15倍,而且施加磁场时间长和磁场强度大有利于磁性明胶微球定位于靶区。文中也介绍了自行设计的外加磁场装置。

关 键 词:磁场  明胶  微球    过锝酸盐

Abstract:In this report, the technique of labelling MG-ms with ~(99m)Tc as pertechnetate in the presence of a reducing agent such as SnCl_2 was described. The distribution of intravenously injected ~(99m)Tc-labelled MG-ms in rabbits at different intervals of magnetic field applied and different magnetic field intensity was investigated by using an externally applied magnetic field and measuring the radioactivity at the rabbit head and other organs. When magnet was used, the radioactivity in the head, target site, was 15 times more than that when magnet was not used. At the same time, the radioactivity of the lung was 5 times less than that when magnet was not used. The newly designed magnetic field equipment was presented.
Keywords:Magnetic field  Gelatin  Microspheres  Technetium  Pertechnetate
