“In vivo, both PGF2α and OXT increased [Ca2+]i in the pottassium chloride-depolarized uterine muscle by 35.7% and 44.6%, respectively, increases similar to the rises in tension in vitro.”
“Results: PGF2α and OXT induced a 30.1% and 35.9%, respectively, increase in developed tension in the potassium chloride-depolarized myometrial strips.”
