Figure 3

Peri-incisional skin cytokine levels for mice treated with saline or morphine beginning at the time of incision. The figure displays cytokine measurements from mice in four different treatment groups: saline, incision/saline, no incision/morphine, incision/morphine. The cytokine levels were assessed at 120 hours after the incisions were made (18 hours after the last dose of morphine). Statistical analysis was performed to detect differences between each set of conditions. N = 8/group.
