Inability to elicit vagal responses from the acid-infused esophagus of pigs.
Acid application in the esophagus and esophageal distension were undertaken in pigs. One group (n = 9) had operatively induced esophagitis. The other group (n = 7) was normal. We found no discrepancy between the groups neither in inspiratory pressure nor in expiratory PCO2 nor in plasma concentrations of pancreatic polypeptide. The results indicate inability to elicit vagal responses from the acid-infused esophagus of pigs.
