In vitro effects of citral on the human myometrium: Potential adjunct therapy to prevent preterm births.

Background: Premature infants contribute to infant morbidity and mortality especially in low resource settings. Information on tocolytic and/or anti-inflammatory effects of several plant extracts, such as citral, could help prevent preterm birth cases and reduce the number of preterm infants. The aim of this study was to evaluate the in vitro tocolytic and anti-inflammatory effect of citral on myometrial tissues of the human uterus.

Anti-inflammatory and utero-relaxant effect of α-bisabolol on the pregnant human uterus.

The aim of this study was to evaluate the anti-inflammatory and utero-relaxant effect of α-bisabolol on the pregnant human myometrium. Samples from the pregnant human myometrium were used in functional tests to evaluate the inhibitory effect of α-bisabolol (560, 860, 1,200 and 1,860 µM) on spontaneous myometrial contractions. The intracellular cyclic adenosine monophosphate (cAMP) levels generated in response to α-bisabolol in human myometrial homogenates were measured by ELISA.

Inhibition of Uterine Contractility by Thalidomide Analogs via Phosphodiesterase-4 Inhibition and Calcium Entry Blockade.

Uterine relaxation is crucial during preterm labor. Phosphodiesterase-4 (PDE-4) inhibitors have been proposed as tocolytics. Some thalidomide analogs are PDE-4 inhibitors.

[Fetus compressus and fetus papyraceous. Clinical differences (report of three cases)].

The items papyraceus fetus and fetus compressus are used like synonymous. The low incidence and the lack of reporting of these cases leads to confusion. Clinical evidence shows significant differences between them and sustain a proper diagnosis.

Synergistic relaxing effect of the paracetamol and pyrilamine combination in isolated human myometrium.

Objective: To evaluate the interaction type of the human uterine relaxant effect of the paracetamol-pyrilamine combination (PPC) in vitro.

Study Design: Uterine strips were contracted with KCl (60 mM) and treated with vehicle or increasing concentrations of paracetamol (100-3200 μM), pyrilamine (3.2-100 μM) or the PPC.
