“…The inclusion of lipocaic here, as an internal secretion of the pancreas, depends upon the work of Dragstedt and co-workers (35,36,37). Their contentions, supported by a great deal of careful evidence, are based upon their findings: (a) that ligation of the ex ternal pancreatic ducts does not result in the characteristic fall in serum lipoids and the rise in liver fat which occurs in depancrea tized dogs not receiving raw pancreas, lecithin, or choline in the diet; (b) that administration of large quantities of the external secretion of the pancreas, collected from pancreatic fistulae, does not alleviate the above changes in depancreatized anilllals; and (c) that their simple alcoholic extract of pancreas, named lipocaic, is very potent in relieving the fatty changes, and does not contain sufficient choline to account for the results.…”
