Effects of locally (at surgical site) administrated buprenorphine on postoperative hypersensitivity in adult and aged mice. Incision-induced thermal (A) and mechanical (B) hypersensitivity were generated in adult and aged mice. At 1 day (for adults) and 1 to 3 days (for aged) postsurgery, operated hind paws were injected with different dosages of buprenorphine, and thermal (A) and mechanical (B) hypersensitivity were measured at 30 and 120 minutes after buprenorphine injection. Data are presented as area under the curve (AUC). Significance within age groups for buprenorphine-produced antihypersensitivity was compared against vehicle treatment (1-way ANOVA; *P < 0.05; **P < 0.01; ****P < 0.0001; n = 5–8). Significance between age groups was assessed by 2-way ANOVA. Buprenorphine dosages are indicated below log x-axis. Veh is vehicle treated conditions. Mouse ages are indicated.
