Intraperitoneal injection of 6 mg/kg of phenyl-p-quinone produced a syndrome consisting of distorted limb and body positions in rhesus monkeys. Intramuscular injection of 1 mg/kg of morphine abolished the syndrome, whereas 16 mg/kg of nalorphine had no appreciable effects on the syndrome. One-half mg/kg of nalorphine reversed the inhibitory effects of 1 mg/kg of morphine on the syndrome.
