Figure 3From: Morphine reduces local cytokine expression and neutrophil infiltration after incisionMyeloperoxidase levels in skin before and after hind paw incision. The skin of mouse hind paws was harvested before, 30 minutes after incision or 2 hours after incision. Incised animals were given saline or morphine of the indicated doses prior to incision. Eight control or incised samples per condition were used. Statistical analysis reflects differences in MPO levels versus control pre-incision levels. **p < 0.01.Back to article page
