Abstract

Krag, E., Krag, B. & Lenz, K. A comparison of stable and ³H-labelled polyethylene glycol 4000 as non-absorbable water phase markers in the human ileum and faeces. Scand. J. Gaslroenl. 1975, 10, 105-108.

Polyethylene glycol 4000 (PEG plus ³H-PEG) was used as volume indicator during ileal perfusion in man. Faeces, urine, ileal infusåtes, and aspirates were investigated. Turbidimetrical assay and liquid scintillation counting (in the faeces radioassay was done after combustion) yielded similar estimates of water absorption and secretion. Tracer amounts of ³H were found in the urine, indicating a minimal absorption. The simplicity of ³H radioassay and the reliability of ³H-PEG as a non-absorbable water phase marker is emphasized.
