Exercise Reduces Morphine-Induced Hyperalgesia and Antinociceptive Tolerance

Figure 5

Morphine increased p-p38 expression in the spinal dorsal horn, and exercise training decreased that effect by (a) Western blot and (b) immunostaining image of p-p38 in the spinal dorsal horn. “a” denotes the statistically significant difference compared to the sedentary+saline group, and “b” denotes the statistically significant difference compared to the sedentary+morphine group.
