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 apruunin (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.
