Exocrine ductalpCO2in the rabbit pancreas

摘要

An improvedpCO2microelectrode has been evaluated and used to investigate whether a significant barrier to diffusion of CO2exists in the rabbit pancreas. The results of this study show the improved Carter and CaflischpCO2microelectrode to be an accurate and reliable tool for measuring pancreatic venous and ductalpCO2. The similarities betweenpCO2values from the pancreatic ducts and small pancreatic veins suggest that there is no barrier to CO2diffusion between small veins and exocrine ducts in the rabbit pancreas, and that ductalpCO2is probably strongly influenced by the CO2tension of the small pancreatic blood vessels.
