Abstract
AIM To observe the effect of gastric distension on fluid absorption in jejunum and to analyze the role of the vagus in the effect induced by gastric distension.
METHODS The experiments were performed in rats with Tilly-Vella jejunal loop in situ using single pass perfusion technique. Polyethylene glycol 4 000 (PEG 4 000) was used as a nonabsorbable volume marker. Jejunal fluid absorption rate was measured by turbidimetry; and transmural potential difference (tPD) was recorded to analyze the transport of electrolyte. ......
