Abstract

Effects of inspired oxygen concentration on metabolism of nitroxide radical were measured in whole mice by using in vivo ESR. Oxygen concentration influenced spin-clearance of nitroxide differently in abdomen and head, suggesting that either O2 concentrations or metabolic mechanisms of nitroxide in the two domains were different.
