The roles of mast cells and extrinsic and vagal neural pathways in the anaphylaxis-induced alterations in motility observed at sites remote from antigen exposure were explored. Rats were sensitized to egg albumin (EA) and prepared with 1) electrodes to monitor intestinal myoelectric activity, 2) an isolated intestinal loop, and 3) either intact vagal innervation or a subdiaphragmatic vagotomy. ...

To evaluate intestinal motility after 80% massive distal small bowel resection (MSBR), we continuously monitored interdigestive and postprandial bowel motility using bipolar electrodes and/or contractile strain gage force transducers in conscious beagle dogs before, and at 0-4 weeks and 8-13 months after the surgery. Fasting duodenal migrating myoelectric (or motor) complexes (MMCs) occurred at...

The methanolic extract of fruit of Benincasa hispida (BHFE) was evaluated for its antidiarrheal potential against several experimental models of diarrhea in rats. BHFE treated animals showed significant inhibi-tory activity against castor oil induced diarrhea and inhibited PGE2 induced enter pooling in rats. It also showed significant reduction in gastro intestinal motility following charcoal m...

BACKGROUND Existing data on the effect of ageing on gastrointestinal motility are few. In this study, we assessed the propulsive effect of all main segments of the gastrointestinal tract in a group of healthy older people. METHODS 16 healthy volunteers (eight women, eight men) of mean age 81 years (range 74-85 years) participated in the study. Gastric emptying and small intestinal and colonic...

The purpose of the present study was to evaluate the prokinetic effects of mosapride with non-invasive assessment of myoelectrical activity in the small intestine and caecum of healthy horses after jejunocaecostomy. Six horses underwent celiotomy and jejunocaecostomy, and were treated with mosapride (treated group) at 1.5 mg/kg per osos once daily for 5 days after surgery. The other six horses ...

Gastrointestinal motility is impaired in a substantial proportion of patients with cirrhosis. Cirrhosis-related autonomic neuropathy, increased nitric oxide production, and gut hormonal changes have been implicated. Oesophageal dysmotility has been associated with increased frequency of abnormal gastro-oesophageal reflux. Impaired gastric emptying and accommodation may result in early satiety a...

Introduction Some effects of 13adrenoceptor agonists on gastrointestinal motility have been investigated in monogastric species (Burks, 1987). Several side effects of /3-blockers are mediated through the central nervous system which is involved in the control of gastrointestinal motility. This study was undertaken to determine the central and peripheral actions of /3!and P2agonists on forestoma...

Intestinal motility was studied in two sheep by electronically recording pressure changes using open-ended p.v.c. tubes placed in the lumen of the intestine and connected to pressure transducers. Flow in the duodenum and ileum was studied concurrently with motility. Both duodenum and ileum showed two types of activity, one progressive and associated with a flow of digesta, and the other localiz...

5-Hydroxytryptamine (5-HT) released from enterochromaffin cells regulates gastrointestinal function in either an excitatory or inhibitory manner. 5-HT(3) and 5-HT(4) receptors in the gut have been the focus of clinical studies on the management of gastrointestinal motility disorders. 5-HT stimulates intestinal propulsive reflexes through 5-HT(4) receptors. 5-HT(4) receptor agonists can stimulat...
