    The biological activity of the new synthetic secretin, Roche, on exocrine pancreatic secretion was determined in conscious dogs with chronic gastric and duodenal fistulae and compared with that of pure porcine secretin (GIH, Karolinska Institutet, Stockholm). The two secretin preparations were found to be equipotent as to pancreatic volume and bicarbonate response on a molar basis. It was concluded that the new synthetic secretin is useful for clinical and research purposes.
