   Sammanfattning : The gastrointestinal tract (GIT) regulates nutrient uptake, secretes hormones and has a crucial gut flora and enteric nervous system. Of relevance for these functions are the G protein-coupled receptors (GPCRs) and the solute carriers (SLCs). LÄS MER

3. 12. A bio-psychological analysis of functional gastrointestinal disorders and a clinical trial of its treatment using psychodrama

   Författare :Ingemar Arn; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Gastrointestinal disorders; IBS; NUD; psychodrama; group psychotherapy; personality; psychoendochrinology; oxytocin; gastrin; somatostatin;

   Sammanfattning : Functional disorders of the gut are regarded as the result of a complex interaction between factors of biological, social and psychological origin. Psychosocial interventions are expected to play a role in the management of patients with this type of symptom. LÄS MER

4. 13. Effect of endogenous and exogenous ghrelin on gastrointestinal function in rat and human

   Författare :Ylva Falkén; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Several peptides derived from the gastrointestinal tract (GI) have been shown to have profound effects on GI motility, food intake and metabolism. Two such peptides, derived from the same prohormone, are the peptides ghrelin and obestatin, discovered in 1999 and 2005, respectively. LÄS MER

5. 14. Studies on the effect of orexin on upper gastrointestinal function in rats and man

   Författare :Marcus Ehrström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Orexin A; orexin receptors; SB-334867-A enteric ganglia; enteroendocrine cells; migrating myoelectric complex; nitric oxide; gastric emptying; gastric acid secretion; leptin; insulin;

   Sammanfattning : Aims: To define the morphological localisation of orexin A (OXA) in the gut, and study the effect of endogenous and peripherally administered OXA on fasting small bowel motility, gastric emptying and acid secretion, hormones involved in glucose homeostasis and pharmacokinetic profile of OXA in rats and humans. Methods: The distribution of OXA, orexin receptors 1 and 2 (OX1 R, OX2R), neuronal nitric oxide synthase (nNOS) and various peptides were studied with immunocytochemistry in rat and human gut.

7. 15. Sex hormones in gastric mucosal physiology and the development of oesophageal, gastric and colorectal adenocarcinoma

   Författare :Richard Shore; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The aim of this thesis was to continue to test the hypothesis that sex hormones play some part in the aetiology and seem to protect women from the development of oesophageal, gastric, and colorectal adenocarcinoma. All three of these cancers display an as yet unexplained male predominance in their respective worldwide incidence rates. LÄS MER
