Study of the effects of polymerized porcine hemoglobin (pPolyHb) in an acute anemia rat model

The objective of this study was to investigate the recovery ability of polymerized porcine hemoglobin (pPolyHb) in a rat model of acute anemia caused by normovolemic hemodilution (ANH). After the ANH procedure, rats were infused with either pPolyHb or red blood cells. The results showed pPolyHb could carry a sufficient amount of oxygen to the tissues to maintain normal aerobic metabolism and hemodynamic stability, without any significant toxic effects on renal and liver function according to pathological, and biochemical analysis. The data suggest pPolyHb may be a good candidate for the treatment of acute anemia in future clinical trials.
