title: Comparison of the influence of the opiate delta receptor antagonist, ICI 154,129, and naloxone on social interaction and behaviour in an open field.
abstract: The influence of a novel opiate delta receptor antagonist, ICI 154,129, and naloxone on social interaction and on behaviour in an open field were compared. At a dose thought to optimally block the delta receptor, ICI 154,129 produced open field behaviour typical of a non-emotional animal: this drug decreased social investigation and the latency to attack. In contrast, naloxone was largely without effect in these tests.
