^(90)Sr-^(90)Y发生器的研制

PREPARATION OF ^(90)Sr-^(90)Y GENERATOR

本文比较系统地介绍为放射免疫治疗用^(90)Sr-^(90)Y发生器的研制,各种分离、分析的条件实验。国产732型阳离子交换树脂成功地被用于^(90)Sr,^(90)Y的分离。得到的^(90)Y可满足医学临床应用要求,^(90)Y的去污因子为10~6。本工艺简便、安全.每740MBq^(90)Y中,^(90)Sr杂质沾污仅为0.74kBq左右。^(90)Sr系剧毒性核素,人终身允许剂量为74kBq.若病人一次接受740MBq^(90)Y治疗。那么接受上百次治疗,方能达到其终身允许剂量。本发生器的淋洗效率可达98%,可推荐用于单克隆抗体的标记,临床放射免疫治疗。

In recent years, ^(90)Y has been considered as one of the best radionuclides for tumor radioimmunotherapy when chelated to tumor-associated antibodies. This evaluation is based on the superior properties of this radionuclide (suitable half-life, pure β-ray emitter of intermediate energy, stable daughter, and suitable chemical properties) and because it is available as a radionuclide generator product by decay of its 28a parent ^(90)Sr.In this paper experimental conditions of the ^(90)Sr-^(90)Y generator are...
