Stability of Pancreatic Enzyme Activities in Duodenal Juice after Pancreatic Stimulation by a Test Meal or Exogenous Hormones

摘要: The activities of pancreatic lipase, amylase, and trypsin were followed after storage at -20 degrees C in duodenal juices collected stimulation by either a test meal or exogenous hormones. all three enzymes stable for up to one year meal. However, nine out 10 hormonally stimulated juices, lipase fell less than 50% the initial activity within weeks storage, third, 60% over similar period. Amylase remained relatively unchanged. in-vitro addition meal, its separate components, glycerol (50%, V/V) stabilised stored least month.
