title: Sensitization of the smooth muscle by prostaglandin E1 contributes to reversal of drug-induced inhibition of the guinea-pig ileum.
abstract: Prostaglandin (PG)E1 reverses drug-induced inhibition of the electrically stimulated guinea-pig ileum. The effect of PGE1 is in part related to a sensitizing action on the smooth muscle and in part to an increased acetylcholine release from the myenteric plexus.
