Antinociceptive effect of intraperitoneal PD 149163 in chemotherapy-induced peripheral neuropathic rats. (A, B) The effect of intraperitoneal PD 149163 (PD: 0, 0.03, 0.1, and 0.3 mg/kg) for the hind paw withdrawal threshold (PWT) to von Frey filaments. (C, D) The effect of intrathecal SR 48692 (SR: 0 or 100 µg) on the antiallodynic effect caused by intraperitoneal PD 149163 (0.3 mg/kg). SR 48692 was delivered 10 minutes before PD 149163 administration. Each line or bar represents mean ± standard error from 6 rats. MPE: maximum possible effect, i.t.: intrathecal administration, i.p.: intraperitoneal administration. *P < 0.05 compared to vehicle.
