In this study, food distribution in the stomach and gastric antral motor activity in patients with longstanding diabetes have been evaluated. With use of a standard gastric emptying test with an acquisition protocol and a refined Fourier algorithm to analyze the data, antral contractions have been characterized and gastric motility parameters were correlated to gastric retention in 20 diabetic ...

A prospective randomized trial of 40 duodenal ulcer patients is reviewed. The patients had one of four operations (selective vagotomy, proximal gastric vagotomy, selective vagotomy plus pyloroplasty, or proximal gastric vagotomy plus pyloroplasty). The gastric emptying of a hypertonic fluid meal was assessed before and three to four months after operation. Selective vagotomy without a drainage ...

The effects of adrenalectomy and adrenal enucleation on liquid gastric emptying were studied in male Wistar rats that were adrenalectomized, adrenal enucleated (AE) or sham operated (SH). The animals in the first group had free access to a 1% NaCl solution (ADS), while the animals in the second and third groups were divided into two subgroups, which ingested either tap water (AEW, SHW) or 1% Na...

Conventional oral dosage forms suffer with many disadvantages. To avoid such limitations controlled release dosage forms are preferred. When these controlled release dosage forms administered by oral route retained in the stomach and release the drug in a controlled fashion continuously in gastrointestinal tract [1]. Controlled release systems also suffer with some limitations such as short gas...

CONTEXT Gamma-aminobutyric acid (GABA) is a potent inhibitory neurotransmitter. There is evidence that GABA(B) receptors located in the dorsal complex and in afferent fibers of the vagus nerve participate in the control of gastrointestinal motility. OBJECTIVE To assess the intracerebroventricularly (ICV) and intravenously (IV) effect of baclofen, a GABA(B) receptor agonist, on liquid and soli...

BACKGROUND The purpose of this retrospective study was to analyse the occurrence of gastrointestinal side effects in enterally fed ITU patients. METHODS We analysed the records of 195 ITU patients fed enterally, over at least five days, with commercial mixtures administered as 20-h infusions. Gastric retention, the number of defecations, and incidents requiring discontinuation of enteral feed...

Lung agenesis and gastric duplication cysts are both rare congenital anomalies. Gastric duplication cysts can present with nausea, vomiting, hematemesis, or vague abdominal pain. Unilateral pulmonary agenesis can present with respiratory distress which usually occurs due to retention of bronchial secretions and inflammations. We report the unique case of right pulmonary agenesis associated with...

Ninety-six weanling male Wistar rats were fed for four weeks one of two different chows: a normal rat chow containing 55.5% (w/w) starch (control group, N = 48) or a rat chow in which starch was partially replaced by lactose, in such a way that the experimental group (N = 48) received 35.5% (w/w) starch and 20% (w/w) lactose. The gastric emptying of fluid was then studied by measuring the gastr...
