Exocrine pancreatic response to secretin and bethanechol in rabbits under hypothermia

Abstract

The effect of the administration of secretin and bethanechol on exocrine pancreatic secretion was studied in rabbits subjected to temperature changes; these involved a drop from 38 degrees C +/- 1 to 28 degrees C +/- 1 (hypothermia) and a subsequent return to 38 degrees C +/- 1 (normothermia).It was observed that hypothermia does not depress the action of secretin on the secretion of fluid, HCO3- and Cl-.Neither was the action of bethanechol on the enzyme secretion affected by changes in body temperature.
