The effect of glucagon on the pressure inside the lower oesophageal sphincter in conscious human subjects and anaesthetized dogs was investigated using the continuous withdrawal method. Glucagon causes a decrease in sphincteric resting pressure in both man and dog and antagonizes the pentagastrin-induced pressure increase of the lower oesophageal sphincter. In experiments on isolated muscle strips of the lower oesophageal sphincter of dogs glucagon decreases the tension and antagonizes the increase in tension induced by pentagastrin. The elevated pressure in patients suffering from achalasia is significantly reduced by glucagon.

A role of gastrointestinal hormones in the regulation of the lower esophageal sphincter was studied in 22 patients with cardiospasm and 21 with reflux esophagitis. The levels of gastrin, vasoactive intestinal polypeptide (VIP), glucagon, insulin, and c peptide were determined by radioactive assay before and after surgical treatment. In opposite abnormalities (cardiospasm and reflux esophagitis), there is a different degree of VIP secretion both at the beginning and after functional exercises. Before and after functional exercises, the level of VIP was higher than in those with cardiospasm. The value of VIP on fasting and after functional exercises may be an additional information to establish the diagnoses of cardiospasm and reflux esophagitis and to evaluate the efficiency of the treatment performed.
