title: Potentiation of oxytocin and prostaglandins-evoked responses by (+) INPEA on isolated rat uterus: its specificity and selectivity.
abstract: The effect of (+) IPNEA on various stimulant drugs was examined on isolated rat uterus. Addition of (+) IPNEA (1 times 10- minus 5 g/ml) to the organ bath, produced marked potentiation in the contractile responses of oxytocin and prostaglandins. Potentiation was less significant to 5-HT, vasopressin, angiotensin and bradykinin. (+) INPEA did not potentiate the responses of oxytocin on isolated rat mammary strip and the responses of prostaglandins on rat stomach (fundus) strip, guinea-pig tracheal chain and guinea-pig ileum. The significance of these findings has been discussed.
