[Physiologic properties of the smooth muscles of the cervix uteri in the rat].
Contractile activity of the isolated smooth muscle of the cervix and cornea was studied in nongravid, gravid (10-21 days) and parturient rats. Smooth muscle of the cervix having alpha- and beta-adrenoreceptors, generated spontaneous contraction, revealed no sensitivity to histamine and small sensitivity to oxytocin and serotonin, whereas the sensitivity to acetylcholine was very high. Prostaglandins (PGF2 alpha and PGE2) could inhibit spontaneous contractions of the smooth muscle in the parturient rat cervix.
