introduction: hydronephrosis is one of the major causes of referring infants for nuclear medicine investigation. renal dynamic study is the most reliable investigation for such children. however direct evaluation of renogram leads to generation of parameters that have no physiological interpretation. the configuration of renogram is very much dependent upon the rate at which radiopharmaceutical...

background functional constipation (fc) and constipation-predominant irritable bowl syndrome (cibs)are two main subtypes of constipation that can be distinguished by the rome ii criteria. measuring colonic transit time (ctt) is an easy and cost effective way to evaluate constipation. this study was conducted to compare the ctt in patients with fc and cibs. materials and methods those patients w...

Intestinal transit of gas is normally adapted to the luminal gas load, but in some patients impaired transit may lead to gas retention and symptoms. We hypothesized that intestinal gas transit is regulated by reflex mechanisms released by segmental distension at various gut levels. In 24 healthy subjects, we measured gas evacuation and perception of jejunal gas infusion (12 ml/min) during simul...

Objective: To analyse the antidiarrhoeal activity of Hemidesmatus indicus (L) R. Br root aqueous (HIRAE) and ethanolic (HIREE) extracts. Methods: HIRAE and HIREE at the dose of 100 and 200mg/kg bw was used to assess antidiarrheal activity in albino rats. Antidiarrheal activity was studied with reference to castor oil diarrhea for assessing faecal score, intestinal transit and enteropooling and ...

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 ...

INTRODUCTION Increased intestinal hydration by activation of the epithelial enzyme linked receptor guanylate cyclase C (GC-C) is a pharmacological principle for treating constipation. Activating mutations in the GUCY2C gene encoding GC-C cause Familial GUCY2C diarrhea syndrome (FGDS) which has been diagnosed with severe dysmotility. AIM To investigate gut motility and hormones before and afte...

PURPOSE The purpose of this study is to use a novel wireless motility capsule to compare gastric emptying and small bowel transit times in critically ill trauma patients and healthy volunteers. MATERIALS AND METHODS We evaluated gastric emptying, small bowel transit time, and total intestinal transit time in 8 critically ill trauma patients. These data were compared with those obtained in 87 ...

Gastrointestinal function was assessed in six patients with rheumatoid arthritis who had developed diarrhoea on treatment with Auranofin. With the administration of Auranofin whole gut transit time decreased markedly (to 50% or less of control values) in five of six patients. The speed of passage of intestinal contents through the colon was certainly increased but attempts to assess transit thr...

BACKGROUND Gastrointestinal dysmotility may be involved in the development of bacterial translocation and infection in patients with liver cirrhosis. The aim of the present study was to describe gastric, small intestinal and colorectal motility and transit in patients with liver cirrhosis and portal hypertension using a magnet-based Motility Tracking System (MTS-1) and standard radiopaque marke...
