An experimental model to perform dynamic studies of exocrine pancreatic secretion in mice.
An experimental model to perform dynamic studies of exocrine pancreatic secretion from mice has been developed. It consists of a microsurgical procedure in anesthetized mice using a stereoscopic microscope. The bile-pancreatic common duct was individualized, isolated and cannulated. A specially calibrated capillary tube was placed in the free end of the cannula and put on a millimetrical rule. Readings of pure pancreatic juice flow rate were performed minute by minute to obtain a flow rate curve. The procedure allowed the discrimination among increasing betanechol doses of 0.1, 0.2, and 0.4 microgram/g body weight.
