Gastric Acid Secretion in a Teleostean Fish A Method for the Continuous Collection of Gastric Effluence from a Swimming Fish and its Response to Histamine and Pentagastrin
Abstract Gastric acid secretion has been measured in the codfish ( Gadus morhua ) equipped with a catheter draining the stomach, by titrating the water swallowed by the fish. Unstimulated acid secretion was found to be very low; in most fishes not exceeding 8 μmol H + /kg.h. Intramuscular injection...

| Summary: | Abstract Gastric acid secretion has been measured in the codfish ( Gadus morhua ) equipped with a catheter draining the stomach, by titrating the water swallowed by the fish. Unstimulated acid secretion was found to be very low; in most fishes not exceeding 8 μmol H + /kg.h. Intramuscular injection of histamine evokes a dose‐dependent secretion of gastric acid, with a maximum acid output of 300 μmol/kg.h occurring with 10 mg/kg histamine dihydrochloride. No acid response was obtained with pentagastrin. |
