1 Propranolol reduced distention-induced gastrin release by approximately 90% (p less than 0.02), whereas phentolamine had no significant effect on the gastrin response to distention. Propranolol gastrin Homo sapiens
2 In additional experiments, we evaluated the effect of the same doses of propranolol or phentolamine on the exaggerated gastrin response to gastric distention that occurred during cholinergic blockade with atropine. Propranolol gastrin Homo sapiens
3 ), propranolol significantly (p less than 0.01) reduced distention-induced gastrin release, whereas phentolamine significantly enhanced the gastrin response to distention (p less than 0.01). Propranolol gastrin Homo sapiens
4 We conclude that: (1) distention-induced gastrin release was reduced by propranolol, suggesting that gastric distention releases gastrin by a beta-adrenergic mechanism and (2) distention-induced gastrin release was enhanced by phentolamine, but only in the presence of atropine. Propranolol gastrin Homo sapiens
5 We conclude that: (1) distention-induced gastrin release was reduced by propranolol, suggesting that gastric distention releases gastrin by a beta-adrenergic mechanism and (2) distention-induced gastrin release was enhanced by phentolamine, but only in the presence of atropine. Propranolol gastrin Homo sapiens
