In three dogs with Heidenhain pouches (HP), gastric fistulas (GF), and duodenal cannulas, acidification of the duodenum with 0.1N HC1 (5 ml/minute) resulted in significant inhibition of GF output (preacidification, 8.66+/-0.58 mEq/30 minutes; postacidification, 5.47+/-0.66 mEq/30 minutes) and elevated peripheral venous blood levels of serotonin (basal, 226+/-64 ng/ml; peak, 521+/-168 ng/ml). Infusion of exogenous serotonin to comparable blood levels (basal, 208+/-38 ng/ml; mean postacidification, 571+/-153 ng/ml) resulted in similar GF inhibition (preacidification, 9.17+/-0.92 mEq/30 minutes; postacidification, 6.49+/-0.56 mEq/30 minutes). Per increment in peripheral blood serotonin of 1 ng/ml, endogenous serotonin inhibited 54.59+/-12.99 muEq/hour and exogenous serotonin inhibited 46.54+/-10.39 muEq/hour, p greater than 0.05. Neither endogenously released nor exogenous serotonin inhibited HP acid output. Using mesenteric venous infusions of serotonin, significant amounts of immunoreactive serotonin were found to escape hepatic inactivation; basal peripheral venous levels of serotonin, 233+/-103 ng/ml, increased to 455+/-127 ng/ml at 10 minutes. During release of endogenous serotonin, 92+/-21% of portal venous serotonin was bound to platelets; in contrast, during intraportal serotonin infusion, only 59+/-18% of serotonin was platelet bound.
