Figure 1. Determination of superoxide dismutase-inhibitable nitroblue tetrazolium reduction in newborn piglet brain before (control) and after fluid percussion brain injury, and after fluid percussion brain injury in polyethylene glycol superoxide dismutase- and catalase-pretreated animals (n = 5). Values are mean+/-SEM. *P < 0.05 compared to corresponding control value;(dagger)P < 0.05 compared to fluid percussion injury value.
