title: Direct action of somatostatin on dispersed mucosal cells from guinea-pig stomach.
abstract: In dispersed mucosal cells from guinea-pig stomach, somatostatin inhibited in a noncompetitive fashion (Ki, 2 x 10(-8) M) the increase in cellular cyclic AMP caused by histamine but not by prostaglandin E1 or phosphodiesterase inhibitors. Somatostatin also inhibited the increase in [14C]aminopyrine uptake caused by low concentrations of histamine probably by interfering with the synthesis of cellular cyclic AMP.
