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

Abstract:

: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.
