Effects of changes in infusion rate versus glucose concentration on absorption in infant miniature pig small intestine



Effects of changes in infusion rate versus glucose concentration on absorption in infant miniature pig small intestine



Gastroenterology 94(3): 722-725



The effect of changes in the rate of infusion versus glucose concentration on glucose, water, and sodium absorption was studied in 20 infant miniature pigs using the single-pass small intestinal perfusion technique. During infusions of glucose loads of up to 75.0 mumol/min, glucose absorption increased similarly whether rate of infusion or glucose concentration was increased. Beyond 75.0 mumol/min, glucose absorption was not altered by changes in infusion rate, but was enhanced by increases in glucose concentration (slope of rate vs. concentration, p less than 0.0001). Net water and sodium absorption were similar in the two groups except for a decrease at the highest glucose concentration (rate vs. concentration at 187.5 mumol/min, p less than 0.05). A glucose concentration of 112.5 mM resulted in maximal glucose, water, and sodium absorption.
