Figure 4. Local infusion of CX546 into the nucleus accumbens (NAc) relieves mechanical hypersensitivity in paw incision (PI)-treated rats.
A. Schematic showing the timeline of pharmacological experiments. B. Intra-NAc infusion of CX546 (400uM/ul) on 4 hours and 1 day after paw incision reduced mechanical hypersensitivity in PI-treated rats. Two-way ANOVA with Bonferroni post-test, Saline group n=6, CX546 group n=8, *p=0.0248, **p=0.0012. C. Intra-NAc infusion of 3-dihydroxy-6-nitro-7-sulfamoyl-benzo[f]quinoxaline-2, 3-dione (NBQX) blocked the analgesic effects of systemic administration of CX546 (10mg/kg) in PI-treated rats. Unpaired two-tailed Student's t-test, Saline group n=8; NBQX group n=8, **p=0.0046.
