| Outline of Final Research Achievements |
Blood circulation consists of heart(pump), vasculature(circuit)and blood(fluid). While derangement of any of them results in circulatory failure, approaches through the third component have been scarce except for transfusion. Whereas artificial oxygen carriers (AOC) remain short of red cells in health, their physical characteristics may work better in disease. In the current study, we tested various AOC and related compounds in animal models to show, 1)protection of ischemia and/or reperfusion injury in bronchus, stomach, brain, inner-ear, skin and skeletal muscle, 2)absence of competitive inhibition on antigen recognition by reticuloendothelial system after a large-dose administration, 3)enhanced radiotherapy and reduction on metastasis after chemotherapy. The results prompted us to change the hypothetical mechanism from aerobic energy synthesis to anti-inflammatory action through suppressed HIF-1a-mediated signal transduction, which better explains the current observations.
