Infusion of lipids into the ileum delays gastric emptying and intestinal transit time in some species. The aim of this study was to characterize the actions of intraluminal lipid infusion on gastrointestinal electrical activity in chickens. Animals were prepared for electromyography with chronic electrodes in stomach, duodenum, and small intestine. Two catheters were chronically placed in the esophagus and ileum to infuse equimolar doses of either oleic acid (OA) or triolein (TO). Both OA and TO, esophageally infused, inhibited the frequency of the gastroduodenal cycle and increased the frequency of antiperistaltic spike bursts in the duodenum. Ileal infusion of OA, but not of TO, produced the same effects. Both esophageal and ileal OA infusion increased the duration of the migrating myoelectric complex (MMC) and decreased the speed of propagation of phase III. In conclusion, intraluminal infusion of lipids modulates gastrointestinal motility by decreasing the frequency of the gastric cycle, increasing duodenogastric refluxes, and elongating the MMC. These actions could delay gastric emptying and increase transit time, which suggests the presence of an "ileal brake" mechanism similar to that described in mammals.

Small Intestine Transit

Background Electroacupuncture (EA) may have a role in the treatment of diarrhoea symptoms. Serotonin (5-hydroxytryptamine, 5-HT) is an important neurotransmitter and paracrine signalling molecule in the gastrointestinal (GI) tract, which initiates peristaltic, secretory, vasodilatory, vagal and nociceptive reflexes. In addition, according to the results of our previous report, EA stimulation mediates GI peristalsis by increasing expression of 5-HT and tryptophan hydroxylase (TPH). Aim To investigate the effect of EA at acupuncture points ST25 and BL25 in a rat model of diarrhoea. Methods A diarrhoea-predominant irritable bowel syndrome (IBS-D) model was induced by Folium Sennae in 24 rats, which remained untreated (n=6) or received EA at ST25 (n=6), BL25 (n=6) or the combination of ST25 and BL25 (n=6). A control group of healthy rats was also included (n=6). After treatment, changes in loose stool and small intestine transit rates, enterochromaffin (EC) cell number, expression of TPH, and faecal/colonic 5-HT contents were measured. Results Loose stool and small intestine transit rates, EC cell numbers, colonic TPH expression and faecal/colonic 5-HT content of IBS-D rats were significantly increased relative to controls (p<0.05) and all these parameters were improved by EA at ST25, BL25, or ST25 and BL25 in combination (all p<0.05 vs untreated IBS-D rats). Conclusions EA at ST25 and/or BL25 had a positive effect on objective markers of diarrhoea in a IBS-D rat model and induced changes in EC cell number, colonic TPH and 5-HT contents. The effects of EA stimulation at ST25/BL25 on IBS-D rats may be mediated by excitation of sympathetic nerves.
