P J Goddard,W E Allen,

Chronic catheterisation of the uterus, ampulla, and abdomen was performed in five ewes using solid-state, catheter-tipped pressure transducers. The catheters remained in place for up to 129 d, allowing in vivo studies of the effects of oxytocin and prostaglandin F(2)alpha (PGF(2)alpha). These agents did not produce any measurable increase in abdominal pressure. Intravenous (i.v.) oxytocin elicited a rapid increase in work done by both the uterus and ampulla. Intramuscular (i.m.) PGF(2)alpha produced a delayed uterine response but little change in the ampulla; i.v. PGF(2)alpha produced a rapid response at both sites. Low plasma progesterone concentrations (< 0.5 ng/ml) were associated with a greater uterine and ampullary response to oxytocin and with an enhanced uterine response to PGF(2)alpha. However, the uterine tube response to intravenous PGF(2)alpha was greatest when plasma progesterone concentrations were high.
