A comparison of stable and 14 C-labelled polyethylene glycol as volume indicators in the human jejunum.

D L Wingate, R J Sandberg, S F Phillips.

Abstract

Polyethylene glycol (PEG plus (14)C-PEG) was measured turbidimetrically and by liquid scintillation counting to compare the validities of these methods during the use of PEG as a volume indicator of intestinal perfusion studies in man. Use of (14)C-PEG results yielded similar estimates of water absorption or secretion. The simplicity of (14)C counting offers practical advantages to the use of (14)C-PEG as a nonabsorbable marker for perfusion studies in man.
