title: Andrenergic reactivity of the gastro-intestinal tract. I. Fundus of the rat's stomach.
abstract: The adrenergic receptors of the fundus of rat stomach are both type alpha and type beta. Activation of the alpha-adrenergic receptors gives a diphasic response in which inhibition precedes excitation. The beta-adrenergic receptors mediate exclusively inhibitory response; the beta-adrenergic component of the inhibitory response is clearly observed only when the alpha-adrenergic component is diminished. The beta-receptors can be assigned, with some reserve, to the betaalpha group.
