The regulation of gastrointestinal motility mainly involves the smooth muscle, neural (extrinsic and intrinsic), and hormonal elements, the glial cells, and the interstitial cells of Cajal. An orchestrated function of all these components is required for the appropriate propulsive movement of the food in the gastrointestinal tract. Gastroparesis, a pathological slowing-down of gastric emptying,...

Siguan acupoints have been used to treat gastrointestinal symptoms in acupuncture practices for a long time. This study aimed to investigate the effects of Siguan acupuncture on gastrointestinal motility under accelerated conditions using a randomized, sham-acupuncture-controlled, crossover study. Twenty-one healthy male subjects were hospitalized and randomized into either a real acupuncture g...

Aim—To determine the eVect of cisapride on gastrointestinal motility in preterm infants. Methods—Cisapride (0.2 mg/kg, 8 hourly ) or placebo was given first for seven days in a double blind randomised crossover study of 10 preterm infants. Gastrointestinal motility was assessed on day 3 of each treatment. The half gastric emptying time (GET1⁄2) was determined by using ultrasonography to measure...

Although gastrointestinal complications are common in patients with renal disease, the effects of renal dysfunction on bowel motility and gut transit times are not well known. We assessed gastrointestinal electromyographic activity, gastric emptying rate, orocolonic transit time, oroanal transit time, and xylose absorption before and after surgically inducing a 66% decrease in glomerular filtra...

AIM To investigate the effects of Xiangbin prescription (XBP), a Chinese herbal concoction, on gastrointestinal motility. METHODS Forty healthy volunteers were recruited for this randomized controlled trial of XBP. Antroduodenojejunal manometry was used to monitor gastrointestinal motility in these subjects. After the subjects had fasted for at least 12 h, XBP (n = 30) or placebo (n = 10) was...

Since 2005, every annual meeting of the Japanese Gastroenterological Association has included a core symposium for functional gastrointestinal disorders. At the 6th annual meeting, the core symposium was 'Pathophysiology and New Treatment'. At the 7th annual meeting, the core symposium was 'Pathophysiology and Motility'. This review summarizes the papers presented at these meetings. At the 6th ...

Background Signalling by NO/cGMP is very important for regulation of vascular tone and gastrointestinal motility. One important signalling pathway of cGMP-dependent protein kinase type I (cGKI) is mediated by IRAG (IP3 Receptor Associated cGKI substrate) which is highly expressed in smooth muscle of cardiovascular and gastrointestinal tissue. In order to elucidate the physiological role of IRAG...

BackgroundReduced gastrointestinal motility can alter the toxicokinetics of acetaminophen poisoning. We report a case of altered acetaminophen toxicokinetics due to delayed gastrointestinal absorption, likely secondary to intestinal trauma/surgery.  Case ReportA 37-year-old woman ingested an unknown amount of acetaminophen and ethanol then stabbed herself in the abdomen. The initial acetaminoph...

Irritable bowel syndrome is one of several highly prevalent functional gastrointestinal disorders (FGID) displaying symptoms of gastrointestinal dysmotility and visceral hypersensitivity. Substantial overlap of symptoms and comorbidities occur not only between irritable bowel syndrome and other FGID but also with gastrointestinal disorders that are not related to motility (eg, celiac disease an...

Gastrointestinal surgical procedures have the potential to disrupt motor activity in various organs of the gastrointestinal tract or, indeed, throughout the entire alimentary canal. Several of these motor effects have important clinical consequences and have also served to advance our understanding of the regulation of gastrointestinal motor activity. This review will focus, in particular, on t...
