The response of the rabbit isolated portal vein to electrical stimulation was potentiated by indomethacin (10 μg/ml). This potentiation was dependent upon frequency but independent of the number of pulses in a train. It is concluded that these results add further support for the idea that indomethacin increases the release of newly synthesized noradrenaline as a result of inhibition of prostaglandin synthesis.
