The effects of capsaicin and mucosal acidification on gastric HCO3(-) secretion were compared in wild-type and prostacyclin (PGI2) IP receptor or prostaglandin E receptor EP1 or EP3 knockout C57BL/6 mice as well as rats. Under urethane anesthesia, the stomach was mounted on an ex vivo chamber, perfused with saline, and the secretion of HCO3(-) was measured at pH 7.0 using the pH-stat method. Ca...

The mechanism of acidification by the urinary bladder of the water turtle was studied in an in vitro system which permitted control and measurement of electrical and concentration driving forces. The rate of hydrogen ion secretion was measured by means of a pH stat technique in the absence of exogenous carbon dioxide and bicarbonate. Transport of hydrogen ion into the solution bathing the mucos...

The gastric mucosa is constantly exposed to conditions that would normally be damaging to living cells. A complex defensive system has evolved that involves multiple mechanisms arranged in a laminar fashion, that as a whole constitute the gastric mucosal barrier to acid. As antisecretory therapy becomes perfected, more attention has been focused on these defensive components of the gastric muco...

Background and aims: The early responses of the oesophageal mucosa to acid perfusion may predict subsequent pathology. Mucosal responses to luminal acid may result either from acid permeating through the mucosa or from other unknown transduction mechanisms. In order to better understand the dynamics of acid permeation into the oesophageal mucosa, we measured interstitial pH (pHint) of the oesop...

introduction domestic and industrial swallowing of caustic substances can cause acute and chronic injuries. in the acute phase of care, focus is on the immediate control of tissue damage and perforation, and in the chronic phase, the focus is on the treatment of pharyngeal narrowing and impaired swallowing. conclusions treatment of esophageal burn lesions is by immediate and delayed removing of...
