Figure 7: Effect of the PPX in the dopamine level on the frontal cortex (A) and spinal cord (B) after reserpine administration (0.25 mg/kg, subcutaneously). Each column represents the mean ± SEM of six mice/group. **P < 0.01, vs. reserpine group; ##P < 0.01, vs. vehicle group (one-way analysis of variance followed by Newman-Keuls post hoc test). N.S.: Not significant; PPX: pramipexole.
