Support of Water Absorption by Rat Jejunum in vitroby Glucose in Serosal Fluid

Abstract
Glucose in the Ringer's fluid bathing the serosal surface supports water absorption by isolated jejunal loops of rat intestine. The rate of water absorption increased with increasing glucose concentration up to 1/2 isosmotic. This maximum rate was about 65% of that found when 1/10 isosmotic glucose was present in the Ringer's fluid bathing the mucosa.
