Comparison of radio-opaque pellets and chromium sesquioxide as inert markers in studies requiring accurate faecal collections.
Radio-opaque pellets (ROP) similar to those currently used to measure gastrointestinal transit time have been compared with chromium sesquioxide to assess their suitability for use as inert markers in the gut. Five healthy subjects took both markers with every meal for two separate three week periods while taking metabolically controlled diets. Overall recovery of both markers was satisfactory;...
متن کاملMORPHINE AND APOMORPHINE INHIBIT GASTROINTESTINAL TRANSIT (GIT) THROUGH TWO DIFFERENT MECHANISMS
Morphine was used as a remedy for the control of diarrhea centuries before it's sedative-analgesic effect was discovered. Although several mechanisms have been proposed for the morphine-induced inhibition of gastrointestinal transit (OIT), the exact mechanism has not yet been identified. On this basis the possible involvement of the dopaminergic system in morphine-induced inhibition of tra...
متن کاملInternal radiation dosimetry of orally administered radiotracers for the assessment of gastrointestinal motility.
Radionuclide imaging using (111)In, (99m)Tc and (153)Sm is commonly undertaken for the clinical investigation of gastric emptying, intestinal motility and whole gut transit. However the documented evidence concerning internal radiation dosimetry for such studies is not readily available. This communication documents the internal radiation dosimetry for whole gastrointestinal transit studies usi...
متن کاملEffects of Artemisia dracunculus essential oil on diarrhea and intestinal transit time in rat gastrointestinal tract
Introduction: Artemisia dracunculus L. belongs to Asteraceae family, and is a medicinal plant widely used in traditional medicine as a remedy for gastrointestinal disturbances. This study was undertaken to evaluate the effects of essential oil of A. dracunculus (EOAD) on the rat alimentary tract. Methods: The EOAD was extracted by Clevenger apparatus using hydrodistillation. LD50 was calcula...
متن کاملMeasuring Cytotoxicity by Bioluminescence Imaging Outperforms the Standard Chromium-51 Release Assay
The chromium-release assay developed in 1968 is still the most commonly used method to measure cytotoxicity by T cells and by natural killer cells. Target cells are loaded in vitro with radioactive chromium and lysis is determined by measuring chromium in the supernatant released by dying cells. Since then, alternative methods have been developed using different markers of target cell viability...
