Abstract:
:The influence of prostaglandins as well as adrenoceptor agonists and antagonists on contractile activity of isolated cervical smooth muscle from term pregnant women was studied. Prostaglandin E2 had an inhibitory effect at extremely low concentrations. Inhibition also was induced by prostaglandin F2 alpha, prostaglandin I2, and 6-keto-prostaglandin F1 alpha, but at considerably higher concentrations. Contractions evoked by noradrenaline or phenylephrine were blocked by the alpha-adrenoceptor antagonist phenoxybenzamine. The beta-adrenoceptor agonist terbutaline acted as an inhibitor, whereas isoprenaline in most cases stimulated contractile activity. The inhibitory action of prostaglandins and especially the high sensitivity to prostaglandin E2 point to a physiologic role of these compounds for cervical dilatation and retraction. A predominance of alpha-adrenoceptors might be of importance for the maintenance of cervical competence during pregnancy.
