Abstract
1. In order to investigate a possible competition for intestinal transport between amino acids and monosaccharides in man, iso-osmotic solutions containing (A) 100 m-mole glycine 1.-1, (B) 100 m-mole glycine and 200 m-mole monosaccharide (glucose or galactose) 1.-1, and (C) 200 m-mole monosaccharide 1.-1, were successively perfused into the upper jejunum of twelve African Zambian patients. None had clinical evidence of malnutrition or small-intestinal disease. By using a double-lumen tube and by reference to a non-absorbable marker (polyethylene glycol, 4000), the rates of absorption of these substances have been calculated for a 30 cm jejunal segment.Keywords
