1. 1. Prevention of Postoperative Duodenal Ileus by COX-2 Inhibition Improves Duodenal Function in Anaesthetised Rats

   Författare :John Sedin; Olof Nylander; Markus Sjöblom; Lars Fändriks; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; duodenum; motility; enteric nervous system; luminal alkalinisation; CFTR; VIP; luminal Cl-; fluid secretion; solute absorption; mucosal permeability; 51Cr-EDTA; luminal osmolality; luminal hypertonicity; glucose; mannitol; orange juice; parecoxib; hexamethonium; mecamylamine; Physiology; Fysiologi;

   Sammanfattning : Abdominal surgery inhibits gastrointestinal motility, a phenomenon referred to as postoperative ileus. Since the postoperative ileus disturbs duodenal physiology it is important to minimize the side effects of this condition. LÄS MER

3. 2. Regulation of Duodenal Mucosal Barrier Function and Motility : The Impact of Melatonin

   Författare :Anna Sommansson; Markus Sjöblom; Olof Nylander; Oliver Bachmann; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 51Cr-EDTA; bicarbonate secretion; duodenum; enteric nervous system; enterochromaffin cell; ethanol; hexamethonium; in vivo; mecamylamine; motility; mucosal permeability; parecoxib; rat; Physiology; Fysiologi;

   Sammanfattning : The duodenal mucosa is regularly exposed to acid, digestive enzymes and ingested noxious agents. It is thus critical to maintain a protective barrier to prevent the development of mucosal injury and inflammation, which are often observed in situations when barrier function is impaired. LÄS MER

4. 3. Paracellular permeability of intestinal epithelia.An in vivo study

   Författare :Britt-Marie Fihn; Göteborgs universitet; []
   Nyckelord :paracellular permeability; intestinal epithelia; deoxycholic acid; cholera toxin; glucose absorption; water transport;

   Sammanfattning : Aim: Investigate the importance of paracellular transport of water and solutes during physiological and pathophysiological conditions. Methods: The transport of small water-soluble inert permeability markers, was studied in jejunum and colon in anesthetized rats and cats during normal conditions and during exposure to cholera toxin (CT) and deoxycholic acid (DCA).

5. 4. Neural control of colonic epithelial transport, motility and permeability in vivo. An experimental study in anaesthetized rats

   Författare :Ying Sun; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enteric nervous system; colonic motility; transmural potential difference; net; fluid transport; permeability; bile acid; nitric oxide; inflammatory bowel disease;

   Sammanfattning : Colonic dysfunction may result in diarrhoea, abdominal pain or constipation, andinflammatory bowel disease, bile acid malabsorption and particularly irritable bowelsyndrome are very common disorders. The role of the enteric nervous system (ENS) inthese diseases is largely unknown. LÄS MER

7. 5. The enteric nervous sytem and infectious diarrhoea. An experimental study in mouse and rat

   Författare :Shirin Kordasti; Göteborgs universitet; []
   Nyckelord :rotavirus; cholera; secretion; potential difference; enteric nervous system;

   Sammanfattning : Aim: To evaluate the role of the enteric nervous system in one of the most common types of infectious diarrhoea worldwide, rotavirus infection, and to further clarify the mechanisms behind neurally mediated intestinal secretion. Methods: The experiments were performed on neonatal and adult mice and adult rats. Experimental setups: In vitro: 1. LÄS MER
