[Simultaneous study of the placental, myometrial and cervical circulations (indium 113 and anemometric thermometry). 2. Effect of xanthinol nicotinate].

The authors have studied the action of nicotinate of xantinol on the placental, myometrial and cervical circulations using an isotope technique (Indium 113) and anemometric thermometry. They show that this product in every case increases the flow through the cervix and has little action on the flow through the placenta, except that in rare cases it lessens it. The action on the myometrial circulation varies from woman to woman. There is a significant negative statistical correlation between variation in the circulation through the cervix and the placenta.
