Figure 5. Effects of PD135158 (80 [micro sign]g) on the thermal nociceptive threshold in the chronic constriction injury and partial sciatic nerve injury models. The ordinate shows the paw withdrawal latency (PWL). The abscissa shows time in minutes after drug injection. Each line represents the mean +/- SD of determinations made in five rats. Injured paw = sciatic nerve-injured paw (right paw); uninjured paw = sciatic nerve-uninjured paw (left paw).
