Prostaglandin concentrations in intra-uterine tissues from late-pregnant sheep before and after labour.
Prostaglandin E (PGE), prostaglandin F (PGF) and 13,14-dihydro-15-keto-prostaglandin F (PGFM) have been measured in cotyledons and myometrium from sheep before and after labour. Fetal cotyledons contained more PGE than maternal cotyledons which in turn contained more than myometrium. The maternal cotyledon contained the highest concentrations of PGF, but the fetal cotyledon was the only tissue exhibiting a statistically significant rise in the concentration of PGF following labour. Concentrations of PGFM were closely correlated with (although usually lower than) those of PGF.
