title: The rabbit ear-withdrawal test: a new analgesiometric procedure.
abstract: The latency to movement of an ear exposed to radiant heat was prolonged after intravenous administration of morphine to rabbits. The quantification of this response in a relatively inactive species that is especially suited for long term and repeated tests suggests that the rabbit ear-withdrawal test will be useful for screening analgesic/anesthetic compounds.
