2. SLADEN These studies were undertaken because it is often assumed that a reduction of luminal pH may be in part responsible for the fluid diarrhoea, which occurs in some patients with the Zollinger-Ellison syndrome and with various forms of sugar intolerance. There is evidence that small reductions of pH may profoundly affect jejunal transport of water and sodium (McHardy and Parsons, 1957), but little is known about such effects of pH in the ileum or colon. In these studies, using rats in vivo, isotonic fluid buffered at different pHs (5 6-7 6) was placed in tied loops of distal ileum (20-30 cm) or proximal colon (5-8 cm) and left for short absorption periods;ROUSSEAU, B.; E, G.
