Effect of morphine on nociceptin-induced scratching, biting and licking response in mice. Morphine was given i.p. 15 min before i.t. administration of nociceptin (3.0 fmol). The duration of scratching, biting and licking induced by nociceptin was determined over a 20 min period starting immediately after injection. Each value represents the mean±s.e.mean of ten mice in each group. **P<0.01 when compared with saline-controls (84.8±14.2 s).
