Abstract

We investigated the effects of N-allylnormetazocine (SKF 10,047) and morphine on the stereotyped behaviors induced by the intraperitioneal injection of phencyclidine (PCP). PCP-induced turning and backpedalling were significantly potentiated by pretreatment with SKF 10,047 (10 mg/kg) but sniffing and head weaving were not. On the other hand, pretreatment with morphine dose-dependently attenuated PCP-induced sniffing and head weaving, but not turning and backpedalling. These results suggest that PCP-induced stereotypy may be mediated by not only a sigma opioid receptor but also some other receptors. In addition, each component of PCP-induced stereotypy may be controlled by different opioid systems and/or neuronal systems.
