Influence of amino acids on gastric adaptive relaxation (accommodation) in rats as evaluated with a barostat
AIM The present study aimed to evaluate the effects of selected straight alkyl chain, hydroxylated chain and branched chain amino acids on gastric adaptive relaxation, as these have previously been shown to have differing effects on gastric emptying. MATERIALS AND METHODS Gastric adaptive relaxation was evaluated using a barostat in rats under urethane anesthesia. The pressure within the ball...
متن کاملDual role of mosapride citrate hydrate on the gastric emptying evaluated by the breath test in conscious rats.
Mosapride citrate hydrate (mosapride) has been known to act as a 5-HT4 agonist and to enhance gastric emptying. However, its mode of action, such as time course and dosage effect, on gastric emptying has not been clarified. This study aimed to clarify these points by the breath test using [1-(13)C]acetic acid in conscious rats. Mosapride significantly and dose-dependently enhanced the gastric e...
متن کاملA case of gastric duplication evaluated by gastric emptying scintigraphy.
Gastric duplications are relatively rare, and communication with the gastric lumen is extremely rare. A 67-year-old man was referred to our hospital because of recurrence of epigastric pain and fullness. An upper gastrointestinal contrast study revealed a double compartment stomach, with gastric duplication starting at the esophagogastric junction outside the greater curvature. Computed tomogra...
متن کاملEffects of straight alkyl chain, extra hydroxylated alkyl chain and branched chain amino acids on gastric emptying evaluated using a non-invasive breath test in conscious rats
AIM Some amino acids been known to influence gastric emptying. Thus we have evaluated the effects of straight alkyl chain, extra hydroxylated alkyl chain and branched chain amino acids on gastric emptying. MATERIALS AND METHODS Gastric emptying was evaluated in rats after feeding with Racol (nutrient formulae) containing [1-(13)C] acetic acid. Using a breath test, the content of (13)CO2 in th...
متن کاملRunning head: Gastric accommodation and motility by MRI and barostat
Background: The barostat is considered the gold standard for evaluation of proximal gastric motility especially for the accommodation response to a meal. The procedure is invasive because it involves the introduction of an intragastric catheter and bag and is not always well tolerated. Moreover, the barostat bag itself may influence motility. Nowadays Magnetic Resonance Imaging (MRI) is able to...
