[Study of functional properties of chemically-modified hemoglobin during circulation in the blood channel].
Functional activity of the solutions of chemically modified hemoglobins (Hb) with different structure had been investigated during the replacement of acute fatal blood loss in dogs. It was found the correlation between polymerization degree of Hb derivatives and alterations of its oxygen-carrying characteristics in the process of circulation. It was shown that decline of functional activity at the prolonged terms of circulation was more expressed for macromolecular Hb derivatives with heterogeneous structure. Therefore chemically modified Hb free from high molecular weight fractions may be considered as a potential oxygen-carrying fluids, because they are capable of more effective support of the oxygen transport level in the organism.
