OWING to the association between alcohol and chronic pancreatitis in man' there has,been considerable interest in the effect of alcohol upon gastro-entero pancreatic (GEP) hormones. Previous estimations of GEP hormones following oral alcohol ingestion have shown raised serum gastrin concentrations in response to 18 per cent and 15 per cent ethanol in man (Becker, Reeder and Thompson2), and Stra...

Although part of the normal gut flora, Escherichia coli strains are also important intestinal pathogens. Diarrheagenic E. coli (DEC) cause a wide variety of gastrointestinal diseases, particularly among children in developing countries, resulting in significant morbidity and mortality (Moyo, 2007; Khairun, 2007; Brandal, 2007; Nguyen, 2005; Rajendran, 2010; Franzolin, 2005). The DEC are differe...

Neuroendocrine tumors, or more properly gastro-entero-pancreatic tumors (GEP-NETs), are cancers of the interface between the endocrine (hormonal) system and the nervous system. A neuroendocrine tumor begins in the hormone-producing cells of the body’s neuroendocrine system, which is made up of cells that are a cross between traditional endocrine cells (or hormone-producing cells) and nerve cell...

Irritable bowel syndrome (IBS) is the most common functional gastrointestinal disorder, affecting about 10 to 20% of the population in developed countries. The mechanisms underlying the symptoms of this condition are poorly understood. Considered initially as the consequence of abnormal gut motility, visceral hypersensitivity, psychosocial factors and brain-gut axis dysfunction, IBS is now ackn...

Large groups of basal-granulated (entero-endocrine) cells occur on the top of villi in the duodenum and upper jejunum of the human fetus older than five months of gestation. This structure was discovered and described by Segi(1935), hence named Segi's cap. By the immunocytochemical technique, somatostatin-, gastrin- and motilin-producing cells were demonstrated. By electron microscopy, EC, D an...

An analysis of published nucleotide sequences of the 5'-untranslated region (5'-UTR) of 7 cardioviruses and 3 aphthoviruses has allowed us to derive a consensus secondary structure model that differs from that previously proposed for the 5'-UTR of entero- and rhinoviruses, though all these viruses belong to the same family, Picornaviridae. The theoretical model derived here was experimentally s...
