title: Analgesic effect of aprotinin in the rat and its inhibition by naloxone.
abstract: Experiments were performed on rats using two analgesimetric tests (tail-flick; hot-plate) before and after injection i.v. of graded doses of aprotinin (12.5, 25.0 and 50 KIU g-1). A dose-related analgesic effect was noted with both tests. Prior administration of naloxone 0.001 mg g-1 i.p. inhibited the analgesic action.
