BACKGROUND/AIMS Although probiotics have been extensively studied in irritable bowel syndrome, data on the impact of probiotics on chronic constipation are scarce. We aimed to evaluate the effects of kefir, which is a probiotic fermented milk product, on the symptoms, colonic transit, and bowel satisfaction scores of patients with chronic constipation. MATERIALS AND METHODS Twenty consecutive...

BACKGROUND Gastrointestinal (GI) disorders are commonly associated with chronic conditions such as diabetes, obesity, and hypertension. Direct consequences are obstipation or diarrhea as opposite aspects of the irritable bowel syndrome, and more indirectly, alteration of appetite, feeling of fullness, flatulence, bloatedness, and eventually leading to altered absorption of nutrients. Moreover, ...

OBJECTIVE The aim of this study was to assess clinical features and colonic transit patterns in Brazilian children with refractory constipation. METHODS From 2010 to 2013, 79 constipated patients received follow-up care in a tertiary hospital. Of these patients, 28 (aged 8-14 years) were refractory to conventional therapy and underwent a simplified visual method of nuclear colonic transit stu...

BACKGROUND Motilin, a peptide hormone has a direct excitatory effect on circular smooth muscle strips derived from the human colon. Reduced plasma motilin concentration has been reported in adults with chronic constipation. Erythromycin, a non-peptide motilin receptor agonist, induces phase 3 of the migrating motor complex (MMC) in the antro-duodenum and also reduces oro-cecal transit time. A p...

Objective- In this study, the general anatomical features of the digestive tube and the transit time of the digestive tube of the Zarudni’s spur-thighed tortoises were examined by contrast radiology. Design - Experimental study. Animals - 4 adult female Zarudni’s Spur-thighed Tortoises (Testudo graeca zarudnyi). Procedures- At a temperature of 25-27°c a set of dorsoventral rad...

The effect of olsalazine on stool output and the transit of a solid radiolabelled meal through the stomach, small intestine and colon was studied in six patients with ulcerative colitis intolerant of sulphasalazine. Olsalazine 250 mg four times daily significantly accelerated gastric emptying (mean +/- SD; 45.3 +/- 24.2 min v 67.3 +/- 33.1 min, p less than 0.05), mouth to caecum transit time (2...

Ageing is associated with an increased incidence of constipation in humans. The contribution that the ageing process makes to this condition is unclear. The aim of this study was to determine the effects of age on faecal output and colonic motility in male C57BL/6J mice and to determine the role that altered tachykinin signalling plays in this process. Total faecal output recorded over a 24h pe...

determination of normal gastric emptying time and small intestinal transit time are useful in detecting gastrointestinal motility disorders and partial obstructions of the pylorus or small intestine. this study was conducted to evaluate iodixanol as a contrast agent in the gastrointestinal tract in new zealand white rabbit. twelve clinically healthy adult rabbits were prepared and kept for two ...

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...

The effects of heat stress on the antimicrobial drug resistance of Escherichia coli of the intestinal tract of swine were studied in animals from a farm that had not been supplementing antimicrobials in feed for the past 10 years. In one study, 10 finisher hogs were heat stressed (34 degrees C) for 24 h. Antimicrobial resistance levels after stress were significantly higher (P < 0.05) when comp...
