UNLABELLED The medical literature states that solid gastric-emptying studies are more sensitive for the detection of gastroparesis than are liquid studies; thus, liquid studies are rarely required. However, we have seen patients with normal solid but delayed liquid emptying. The purpose of this investigation was to determine whether a study of clear liquid gastric emptying has added value for t...

The effects on gastric emptying of a solid meal of the specific 5-HT3-receptor antagonist ICS 205-930, 10 mg and 20 mg intravenously were assessed with a scintigraphic technique in 12 normals. The 50% emptying time was less, the lag phase was shorter and the post lag emptying rate was faster after 20 mg ICS 205-930 (p less than 0.02). After 10 mg ICS 205-930 the lag phase was significantly shor...

There are few complications associated with intravenous regional anaesthesia but convulsions with loss of consciousness induced by local anaesthetic toxicity may result in pulmonary aspiration. In many hospitals, patients are fasted prior to the procedure although such a delay would be of little value if gastric emptying was inhibited following painful injury. Utilizing the kinetics of paraceta...

We examined the relationships between gastric volume and duodenal glucose load in the regulation of gastric emptying in adult male rhesus monkeys. Intragastric glucose loads (0.125 g/ml) of volumes ranging from 150 to 375 ml empty from the stomach at the same rate from 20 to 120 min. However, to achieve these equivalent emptying rates, progressively larger volumes were emptied in the initial 20...

A B S T R A C T Gastric emptying and secretion, as well as intragastric volume and composition, were determined simultaneously in three patients with Zollinger-Ellison syndrome and in seven normal subjects. Gastric hypersecretion was observed in patients with ZollingerEllison syndrome and in normal subjects receiving pentagastrin. In contrast, the fraction of gastric contents emptied per minute...

This study investigated in eight healthy male volunteers (a) the gastric emptying pattern of 50 and 100 grams of glucose; (b) its relation to the phase of interdigestive motility (phase I or II) existing when glucose was ingested; and (c) the interplay between gastric emptying or duodenal perfusion of glucose (1.1 and 2.2 kcal/min; identical total glucose loads as orally given) and release of g...

A comparison was made of two techniques to measure the rate of gastric emptying. A noninvasive scintigraphic technique using a gammacamera and an invasive aspiration technique based on dye dilution were performed simultaneously. Seven healthy male volunteers each consumed two different liquid meals on two separate occasions. Scintigraphic measurements were performed continuously with aspiration...

The prevalence of the latent form of sheep abomasal phytobezoariasis and the effect of husbandry management on this condition were determined in a survey in and industrial abattoir in Urmia from June 2005 to July 2006. The effect of different age groups and seasons on the prevalence of sheep abomasal phytobezoariasis was also determined. Furthermore, the histological changes in the affected abo...
