Abstract

The present study was carried out to determine the relationship of beta 1- and Beta 2-subtype to amylase release and cyclic AMP (cAMP) accumulation in rat parotid tissue. In in vitro experiments, beta-adrenergic agents (isoproterenol and dobutamine)-induced amylase release and cAMP accumulation were all completely inhibited by the beta 1-antagonist metoprolol, but incompletely inhibited by the beta 2-antagonist butoxamine. The beta 2-agonist procaterol caused little or no amylase release or cAMP accumulation. Our results suggest that both amylase release and cAMP accumulation in rat parotid tissue may be selectively induced by beta 1-adrenergic stimulation.
