Abstract
An improvedpCO2 microelectrode has been evaluated and used to investigate whether a significant barrier to diffusion of CO2 exists in the rabbit pancreas. The results of this study show the improved Carter and CaflischpCO2 microelectrode to be an accurate and reliable tool for measuring pancreatic venous and ductalpCO2. The similarities betweenpCO2 values from the pancreatic ducts and small pancreatic veins suggest that there is no barrier to CO2 diffusion between small veins and exocrine ducts in the rabbit pancreas, and that ductalpCO2 is probably strongly influenced by the CO2 tension of the small pancreatic blood vessels.
