  • Title: The effect of beta-adrenergic blocking drugs and inhibitors of phosphodiestease on histamine release from isolated mast cells.
    Author: Nosál R, Menyhardtová Z.
    Journal: Agents Actions; 1977 Jul; 7(2):231-6. PubMed ID: 70989.
    Abstract:
    Differences in the histamine liberation from isolated rat mast cells after beta-adrenergic blocking drugs were demonstrated. In equimolar concentrations histamine release was induced by Kö 1124, Kö 1500, Kö 1560, Kö 1561 and propranolol. Alprenolol, oxprenolol, propranolol, and trimepranol significantly decreased thehistamine release induced by compound 48-80. The release of granules from cells was inhibited quantitatively more than the release of histamine. This enabled us to surmise the selective effect of beta-adrenergic blocking drugs on cell membranes of mast cells. The possible mechanisms of release reaction are discussed.
