摘要

实验结果表明

99m

Tc-CDO的标记率受体系的pH值影响较小

而

99m

Tc-CDO-MeB只有在pH=3.5—4.0时标记率才能大于90％。小鼠体内分布实验表明

99m

Tc-CDO-MeB在动物心肌中有较高的吸收

但随时间延长而迅速清除。心/肝比值在给药后1、5和10min时分别为3、1.5和0.8。

99m

Tc-CDO在心、脑中的浓聚明显低于

99m

Tc-CDO-MeB。

Abstract

This paper reports the preparation and biodistribution of 99mTc-cyclo-hexanedione dioxime （99mTc-CDO） and its methaneboronic acid adduct （99mTc-CDO-MeB）. The result showed that pH value exerts greater effect on the labelling yield of 99mTc- CDO- MeB than that of 99mTc- CDO. When pH value was 3.5-4.0

the labelling yield of 99mTc-CDO-MeB was higher than 90%. Biodistribution experiment showed that 99mTc-CDO-MeB was taken by heart and brain in the first few minutes after intravenous injection. The uptakes of 99mTc-CDO-MeB by heart and brain were higher than those of 99mTc- CDO.
