抜粋

The effects of ethylketocyclazocine (EKC) on the stereotyped behaviors induced by intraperitoneal injection of phencyclidine (PCP) or N-allylnormetazocine (SKF 10,047) were examined. EKC markedly antagonized PCP-induced stereotyped behaviors such as sniffing, head-weaving, turning and backpedalling. On the other hand, EKC failed to antagonize SKF 10,047-induced stereotyped behaviors, which are PCP-like stereotyped behaviors, except sniffing and head-weaving at 0-15 min after the SKF 10,047 injection. PCP-induced turning and backpedalling were potentiated by pretreatment with SKF 10,047, while PCP-induced sniffing and head-weaving were not. EKC failed to affect the enhancing effect of SKF 10,047 on PCP-induced turning and backpedalling. These results suggest that part of the PCP- and SKF 10,047-induced stereotypy may be mediated by different neuronal mechanisms.
