Neurohormonal control of intestinal transit

Neurohormonal control of intestinal transit L

horbar; This review shows that numerous neuropeptides and hormones are involved in the regulation of intestinal transit. Many gastrointestinal hormones known to act on smooth muscle to influence muscle contractility also play a role in the genesis of abrupt changes associated with alimentary behaviour. In many monogastrics and ruminants, the cyclic occurrence of the migrating motor complex (MMC...

INTESTINAL MOTILITY Impaired reflex control of intestinal gas transit in patients with abdominal bloating

Background: Patients with abdominal bloating and distension exhibit impaired transit of intestinal gas which may lead to excessive gas retention and symptoms. Furthermore, we have previously shown that intestinal gas transit is normally accelerated by rectal distension. We hypothesise that in patients with functional bloating this modulatory mechanism fails and impairs gas transit. Methods: In ...

New methods of studying intestinal transit times.

[The effect of cisapride on intestinal transit].

Cisapride is known to accelerate gastrointestinal motility in various diseases with gastrointestinal motor abnormalities, and in normal subjects. In this study, we developed a new method to evaluate intestinal transit by radio-opaque markers, and evaluated the effect of oral doses of cisapride on intestinal transit in 6 normal subjects. Twenty markers were ingested with breakfast, and abdominal...

Effect of Iranian Black Tea Extract and Its Isolated Thearubigins on Intestinal Transit Time in Mice

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...
