[Hemoglobin polymers during their circulation in the vascular bed of animals].
The effect of molecular mass of 1 g/kg hemoglobin (Hb) modified by glutaraldehyde and pyridoxal-5'-phosphate on the duration of Hb presence in the rabbit circulation was studied. Hb concentration and met-form content were measured in plasma samples taken 5 min, 6, 18 and 24 h after the injection. Gel and ion exchange chromatography was performed. Predominant clearance of low-molecular fractions within the first 6 h of circulation was shown, it was followed by a rise in high-molecular fraction (greater than 300,000) content, that might be caused by the interaction of modified Hb with plasma proteins. This corroborates the decrease in the overall charge of the circulating fractions.
