PG - 254-6 AB - The Straub tail reaction (STR) induced by intracerebroventricular injection (ICV) of morphine was significantly antagonized by beta-funaltrexamine (beta-FNA, mu antagonist), given intracerebroventricularly (ICV), but not naltrindole given ICV (NTI, delta antagonist) or SC norbinaltorphimine given subcutaneously (SC) (nor-BNI, kappa antagonist). When given either SC or ICV the kappa-agonist, U-50,488 H markedly suppressed the STR elicited by ICV morphine; these effects were reversed by nor-BNI. These results suggest that the activation of supraspinal kappa receptors can inhibit the ICV morphine-induced STR which results from activation of supraspinal mu receptors.
