the use of manometry, i.e. the recording of pressures within hollow viscera, after being successfully applied to the study of esophageal and anorectal motor dysfunctions, has also been used to investigate physiological and pathological conditions of the small bowel. by means of this technique, it has been possible to understand better the normal motor functions of the small intestine, and their...

background nonalcoholic fatty liver disease (nafld) is the most common cause of chronic liver disease in western world. however, nafld shows an increasing trend in china every year, which has attracted the attention of national health authorities. the previous studies have shown that nafld caused severe gastrointestinal motor disorders, but little is known about the interstitial cells of cajal ...

Introduction: In this study, the effects of black tea extract of Iranian tea plant (Camellia sinensis var sinensis) and its polyphenolic pigment thearubigins were investigated on mice intestinal transit time. Method: Thearubigins were isolated by liquid-liquid fraction method. The effects of black tea extract and isolated thearubigins on intestinal propulsion were measured by charcoal propulsio...

We have previously reported that restraint stress inhibits small intestinal motility in rats, and that the adrenergic beta3-antagonist SR59230A administration recovered the inhibition. In the present study, we compared the effects of restraint stress and norepinephrine on small intestinal motility using alpha- and beta-adrenergic antagonists. SR59230A did not recover the norepinephrine-induced ...

background: irritable bowel syndrome (ibs) is the most common disorder diagnosed by gastroenterologists seen in about 40-50% of patients seeking care from a specialist. ibs has been treated with selective serotonin reuptake inhibitors, but there is not enough evidence from controlled trials for their effectiveness. materials and methods: the aim of the study was to compare the effects of fluoxe...

A post-mortem vigorous movement of the intestine is a common finding in the rabbit. WARMOES (1925) studied this phenomenon and concluded that the increased intestinal motility would be due to the agony of the intramural nerve plexus, since the enhanced intestinal motility survived after section of both vagi and transection of the mesentery while it was abolished by either cocaine or nicotine. J...

UNLABELLED The disease mechanisms associated with onset and secondary effects of rotavirus (RV) diarrhea remain to be determined and may not be identical. In this study, we investigated whether onset of RV diarrhea is associated with increased intestinal permeability and/or motility. To study the transit time, fluorescent fluorescein isothiocyanate (FITC)-dextran was given to RV-infected adult ...
