Fig. 1. Left ventricular developed pressure (LVDP) as percent of the preinfusion (baseline) value during infusion of neutrophils and/or drugs for 10 min with 30 min of recovery. Values are mean ± SD. PMN = neutrophils; ISO = isoflurane; SEV = sevoflurane; PAF = platelet-activating factor; SOD = superoxide dismutase. *P < 0.05, PMN–PAF versus  all other groups.
