Abstract:
:The aim of this paper was to study the influence of prostaglandins compounds on the pregnant human uterus in situ. Recordings of uterine motility were made on 14 pregnant women by measuring the amniotic pressure. PGE1 alpha and PGF2 alpha were administered intravenously as single injections. It was found that PGF2 alpha and, to a minor extent, PGE1 alpha had a stimulating effect characterized by an increment of tone. The threshold dose to induce contractility was 8 times greater for PGF2 alpha than it was for PGE1.
