^(25)Ⅰ标记人血白蛋白在家兔体内生物半减期的测定

Determination of Biological Half-Life of ^(125)(?)-labelled Human Serum Albumin in Rabbits

本文报道用^(125)I 标记的两种工艺生产的人血白蛋白制品,在两组家兔体内进行生物半减期的对比实验,通过测定和直线对数方程计算,两种白蛋白在家兔体内的生物半减期分别为69±26小时和85±15小时,标记人血白蛋白在两组家兔体内存留时间均在10天以上。结果表明,两种工艺生产的人血白蛋白制品其内在质量和稳定性是一致的。

A comparative experiment with the biological half-life of ^(125)I-labe- lled human serum albumin prepara- tions,produced by two kinds of te- chnological process,was performed in rabbits.The biological half-life of two human serum albumin prepa- rations in rabbits,obtained from de- termination and linear logarithmic equation calculation,was 69±26 hours and 85±15 hours respectively. The survival time of every labelled human serum albumin preparation in two groups of rabbits was above 10 days.Result of the experiment show- ed that the intrinsic quality and stability of the human serum albumin serum albumin preparation,produced by the two different technological processes,were in agreement.
