This study was designed to determine the role of extrinsic gastric innervation in mediating the inhibitory effects of jejunal infusion of mixed nutrients on canine interdigestive gastric motility patterns. Four dogs underwent transection of all extrinsic and intrinsic neural continuity to the stomach except for careful preservation of vagal innervation (stage 1). Antral manometry catheters, antral electrodes, intestinal electrodes, and a jejunal infusion catheter were placed.

Conversely, in infected ferrets on days 8-12 postinfection (PI), vagotomy did not abolish jejunal motility and PD.

The effect of aminophylline on the food-induced hyperemia was found to be dependent on motility. Aminophylline had no effect on the hyperemia when motility was high but inhibited the hyperemia when motility was low. Vasodilations produced by intra-arterial infusions of adenosine, how

The aim of the study was to clarify whether 5-hydroxytryptophan (5-HTP) stimulates the postprandial motor pattern of the duodenum in a similar way as that of the adjacent jejunal segment in dogs. Computerized analysis of motor patterns recorded by closely spaced strain gauges focused on the temporal and spatial distribution of the contractions. Results indicate that 5-HTP increased the incidence and the length of the spread of contraction waves after both an acaloric and a nutrient meal in the duodenum as well as in the adjacent jejunal segment.

Transmural potential difference (PD) and intraluminal pressure in the perfused jejunal loop were also monitored. Vagal stimulation (20 Hz, 20 V, and 0.5 ms for 1 min) resulted in jejunal fluid movement in the direction of secretion, a rise in transmural PD, and an increase

Streszczenie:

The construction of a gastric substitute pouch after gastrectomy for gastric cancer has been proposed to help ameliorate postprandial symptoms and nutritional performance. Adequate reconstruction after gastrectomy is an important issue, because postoperative patient quality of life (QOL) primarily depends on the reconstruction method. To this end, jejunal pouch (JP) reconstructions were developed to improve the patient's eating capacity and QOL by creating large reservoirs with improved reflux barriers to prevent esophagitis and residual gastritis. It is important that such reconstructions als

Three dietary fibres with different physicochemical properties were studied in healthy humans for their effects on small intestinal motility and postprandial hyperglycaemia. Duodeno-jejunal motor activity was evaluated electromyographically for 180 min in six subjects who had ingested a test meal composed of glucose alone or glucose with 15 g of wheat bran (WB), sugar beet (SB) or ispaghula (I) fibres. Glucose and insulin concentrations were determined during the same period. Each subject received each of the four test meals randomly during a 4 d period. Addition of SB or I to the glucose meal

The present study has shown, for the first time, that the presence of high-amplitude propagating contractions induced by bisacodyl is associated with a significant reduction in small bowel motility. These findings support of possible existence of a reflex pathway that causes inhibition of small bowel motility in response to rectal distension.

The aim of this study was to clarify if small doses of neurotensin (2.5 and 5.0 pmol∙kg−1∙min−1, i.v.) in dogs alter the postprandial motor pattern of the duodenum in comparison with the adjacent jejunum. The intestinal motor patterns were quantified by means of closely spaced strain gauge transducers and a computerized method. An acaloric viscous meal of cellulose was used to induce postprandial motility. Gastric emptying was measured radiographically. During intravenous control infusion of saline, the characteristics of duodenal and jejunal motor pattern were significantly different. The duo

In this study, we investigated the role of intrinsic nerves of the small intestine on phase III migration of the migrating myoelectric complex. Fasting myoelectric activity was recorded from the small bowel in chronically instrumented dogs. Once control experiments were completed, the animals were divided into two groups and were reoperated. In the first group of five dogs, a 1.5-g/dl aqueous solution of cobaltous chloride (shown to induce degeneration of intestinal intrinsic nerves) was infused close intra-arterially to perfuse a 15-cm segment of jejunum.

The purpose of the study was to compare colonic motor patterns before and after a single abdominal dose of X-rays in dogs. Recordings were made from five serosally implanted strain gauges at equidistant intervals along the colon in seven dogs (2 dogs also had 2 jejunal electrodes and 1 had ileal electrodes). Control recordings were made for 3 h in the fasted state and daily for 2 wk after an absorbed X-ray dose of 938 cGy was delivered to the abdomen. The duration of migrating colonic motor complexes decreased from 7.2 +/- 0.5 to 3.9 +/- 0.4 min while the mean amplitude fell from 10.3 +/- 0.6

The aim of the experiments was to examine, in vitro, the role of the enteric nervous system in the relationship between motor activity and transmural potential difference (PD) in the guinea pig jejunum and colon using the nerve blocking agents tetrodotoxin (TTX) and aconitine. Histological data showed that perfusion of the intestinal segments with gassed Hepes solution was essential for the maintenance of transmural PD. Disruption of the mucosa was associated with a loss of spontaneous fluctuations in transmural PD without any loss of spontaneous motor activity. Under spontaneous conditions, a

(1) Background: Type 2 diabetes (T2D) is associated with a duodenal hypermotility in postprandial conditions that favors hyperglycemia and insulin resistance via the gut-brain axis. Enterosynes, molecules produced within the gut with effects on the enteric nervous system, have been recently discovered and pointed to as potential key modulators of the glycemia. Indeed, targeting the enteric nervous system that controls gut motility is now considered as an innovative therapeutic way in T2D to limit intestinal glucose absorption and restore the gut-brain axis to improve insulin sensitivity.
