Abstract

The gastric contents of infants usually contain a certain amount of amylase as a result of the presence of swallowed saliva1 and regurgitated duodenal juice, but, even excluding this amount, the addition of gastric contents to pancreatic extract (fresh hog pancreas extracted in saline solution) increased its starch-liquefying activity nearly eightfold (table). As duodenal contents rarely can be collected without some contamination with gastric contents, the results of the determination of the amylase values of duodenal contents will vary with the degree of admixture of gastric contents.2
