Abstract: The purpose of this work was to investigate the effect of oxytocin on prostaglandin F (PGF) concentrations in uterine venous effluent. PGF was measured in utero-ovarian venous plasma from three pregnant ewes and in posterior vena caval plasma from two puerperal ewes, during oxytocin administration. Oxytocin caused 4.9 - 5.3-fold increases in PGF concentrations in the pregnant animals, the response increasing towards term. In the puerperal animals oxytocin caused 3.7 - 17.2-fold increases in PGF concentrations with a marked latency in the response. Measurement of uterine activity and progesterone and total unconjugated oestrogen concentrations indicated that neither uterine contractions nor a decreased uterine blood flow accounted for the elevated PGF levels stimulated by oxytocin. |
