Using 3 outbred dogs with pancreatic, gastric and jejunal fistulas, we examined changes in pancreatic exocrine secretion, duodenal pH and plasma CCK concentration after intragastric or intrajejunal administration of ethanol. Intragastric administration of 20% or 40% ethanol significantly lowered the pH in the duodenal cavity, and pancreatic fluid secretion and bicarbonate excretion were stimula...

BACKGROUND p53 gene mutations have been reported in over half of all human cancers and they appear to occur in the early stage of cancer, thus indicating the important role that such mutations may play in the carcinogenesis of the digestive tract. This study investigated the differences in p53 abnormalities between cancers of the upper and lower gastrointestinal tract. MATERIALS AND METHODS T...

Our body is able to make use of the metabolic sources in the environment by way of the alimentary tract. In order for it to serve as a conduit for the food and other essential substances, it has to undergo specific functions such as food propulsion, secretion of digestive juices, and absorption of simplified nutrients and vitamins, among others. Needless to say, any interruptions in the continu...

fungal agents, especially yeasts, are resident in digestive system as microflora and they can invade the mucosal tract in animals with predisposing factors. the prevalence of the resident fungal flora in the digestive tract of healthy broilers and layers during april to september 2008 was investigated. the samples were taken from the preventriculus, jejunum and cecum contents of 120 birds and c...

The fundamental gastrointestinal functions include motility, sensation, absorption, secretion, digestion and intestinal barrier function. Digestion of food and absorption of nutrients normally occurs without conscious perception. Symptoms of functional gastrointestinal disorders are often triggered by meal intake suggesting abnormalities in the physiological processes are involved in the genera...

As incidence data on gastroenteropancreatic neuroendocrine tumours (GEP-NETs) have so far only been retrospectively obtained and based on inhomogeneous material, we conducted a prospective study in Austria collecting all newly diagnosed GEP-NETs during 1 year. Using the current WHO classification, the tumor, nodes, metastases (TNM) staging and Ki67 grading and the standard diagnostic procedure ...
