Abstract

When phenol red and polyethyleneglycol were used simultaneously as nonabsorbable markers in perfusion studies of the absorptive capacity of high jejunum in humans, apparent absorption was the same when calculated from either marker. This similar indication of dilution and of absorption by the two markers was found in normal subjects and in patients with nontropical sprue, whether aqueous or saline solutions of dextrose were infused. The similarity strengthens the evidence that either phenol red or polyethyleneglycol is a satisfactory???nonabsorbable??? marker compound to indicate dilution in perfusion studies of dextrose and electrolyte absorption in limited segments of human intestine.
