title: [Modification of smooth muscle contractility by Cordemcura].
abstract: Cordemcura causes a dose-dependent inhibition of noradrenaline contractions of isolated rabbit aorta as well as of isolated guinea pig ductus deferens. In both organ preparations analogous intensity of effect has been observed. In different intestinal isolated organs Cordemcura also produces a dose-dependent inhibition against different agonists. The Ba2+-induced contraction is inhibited to approximately the same extent as various receptor-induced contractions. Consequently a specific receptor function on smooth muscle has to be excluded with regard to Cordemcura. Furthermore Cordemcura has a bronchodilatory effect. This property could be proved by the protection effect as observed in the inhalative histamine-induced bronchoconstriction in guinea pig.
