  • Title: A dose-response comparison of PGA2, PGE1 and PGE2 using the phenylephrine-stimulated perfused oviduct of the rabbit.
    Author: Heilman RD, Strainer SM.
    Journal: Prostaglandins; 1976 Jul; 12(1):139-48. PubMed ID: 986673.
    Abstract:
    The phenylephrine-stimulated perfused oviduct of the rabbit was evaluated as a model for studying the activity of prostaglandins that produce inhibition of the oviducal smooth muscle. Elevation of the normal "tone" of the oviduct by perfusing phenylephrine through the lumen permitted quantitation of the responses to PGA2, PGE1 and PGE2 by measuring the magnitude of the inhibitory response produced by the agents. PGE2 was relatively more potent, efficacious and specific for the oviduct than PGA2 or PGE1. It was concluded that the model was suitable for comparative dose-response studies of PGA2, PGE1 and PGE2 and their analogs.
