  • Title: Pancreatic exocrine secretion in the pig following test meals of different composition and intra-duodenal loads of glucose and maltose.
    Author: Nunes CS, Corring T.
    Journal: Horm Metab Res; 1979 May; 11(5):346-51. PubMed ID: 478430.
    Abstract:
    Eleven pigs were fitted with pancreatic and duodenal fistulae, and pancreatic juice collected permanently. Amylase, chymotrypsin, lipase and total proteins were determined in juice collected within 2 and 6 hours after different test-meals or intraduodenal loads of glucose and maltose. In the pancreatic juice of pigs adapted to a high-lipid diet and submitted to a high-carbohydrate test-meal the activity of amylase was increased by 50%. When the consumption of the high-lipid meal was associated with an intraduodenal load of 100 g of glucose all the enzyme activities were stimulated when compared to the effect of meal alone, but only the activity of amylase was significantly increased (+ 82%). In the juice of pigs adapted to a balanced diet and submitted to intraduodenal loads of 150 ml of water, 50 g of glucose, 50 g of maltose and 150 g of maltose, the enzyme activities remained almost constant with the load of water and 50 g of maltose but with 50 g of glucose and 150 g of maltose loads, amylase activity was increased by 20% and 30% respectively. It is suggested, that the exocrine pancreas of the pig adapts itself rapidly to the changes in the size of the intestinal pool of starch hydrolysis products.
