Gastroduodenal motor activity associated with gastric emptying rate in sheep.

A relation between gastroduodenal muscle contractions and gastric emptying

Studies of gastric emptying in dogs, rats, and man have demonstrated that solutions of various substances empty in a characteristic manner. This topic has been reviewed by Hunt (1963). The rate of emptying of test meals from the stomach is influenced by many factors, including volume (Hunt and Macdonald, 1954), osmotic pressure (Hunt, 1956), titratable acidity (Hunt and Knox, 1962), and chemica...

Pancreatic metaplasia of gastric mucosa associated with gastroduodenal ulcer.

Metaplasia represents the process of transforming a well-differentiated adult tissue into another type of adult tissue. Pancreatic metaplasia of the gastric mucosa represents the process in which the normal mucosa of the stomach is replaced with pancreatic formations, which mimic the structure of pancreatic acini. We describe the case of a male patient aged 39 who was admitted for abdominal pai...

Roles of prostaglandin E2-EP1 receptor signaling in regulation of gastric motor activity and emptying.

It is widely accepted that the inhibition of gastric motor activity as well as the maintenance of gastric mucosal blood flow and mucous secretion are important for the homeostasis of the gastric mucosa. The present study was performed to ascertain whether or not endogenous PGs, which can protect the stomach from noxious stimuli, affect gastric motor activity and emptying. The myoelectrical acti...

Factors associated with delayed gastric emptying in patients with stent placement for malignant gastric outlet obstruction

BACKGROUND AND STUDY AIMS Delayed gastric emptying (DGE) is an important factor in determining the clinical outcome in patients with stent placement for malignant gastric outlet obstruction but the factors associated with DGE remain unclear. The aim of this study was to investigate whether clinicopathologic data could be used to identify the factors for DGE in such patients. PATIENTS AND METH...
