We studied the effect of Fe2+ ions in polymerized hemoglobin (Krunidon blood substitute) and in molecular hemoglobin (Sigma) on OH radical initiation in the Fenton system. It was found that polymerized hemoglobin, as a component of Krunidon preparation, in contrast to hemoglobin tetramer, did not intensify OH radical generation. The oxidant potential of Krunidon was evaluated in vivo by measuring malondialdehyde level in dog blood plasma after repeated intravenous administration (5 days in a dose of 114 mg/kg) as a biomarker. Administration of the preparation did not significantly increased malondialdehyde content on days 1 and 4 after exposure and did not affect total protein content in blood plasma. Our findings suggest that polymerized hemoglobin in the Krunidon preparation exhibits no pro-oxidant activity and can be used as the basis for the development of non-oxygenic forms of blood substitutes.
