Abstract：
:The rate of elimination from rat and goat circulation of 125I-labelled goat haemoglobin and its complexes with human and goat haptoglobin in goat circulation, was studied. The half-life time t1/2 of haemoglobin in rat circulation was 1.5h, whereas in goat circulation -- 4 h, and was 10 times shorter than t1/2 for its complexes.
