1. 21. Ghrelin action on gastrointestinal functions and appetite in rat and man

   Författare :Fredrik Levin; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Ghrelin; ghrelin-receptors; gastrointestinal motility; migrating myoelectric complex; gastric acid secretion; gastric emptying; appetite; food intake; disinhibition; restraint; hunger; obesity;

   Sammanfattning : To study the effect of ghrelin on the contractility of smooth muscle strips in vitro as well as the effects on fasting small bowel motility and acid secretion in vivo in rats and gastric emptying in rats and humans. To study the effect of peripherally administered ghrelin on plasma levels of glucose, insulin, glucagon, orexin A (OXA), somatostatin and gastrin in rats and ghrelin, cholecystokinin (CCK), glucagonlike peptide-1 (GLP-1), peptide YY (PYY) and motilin in humans.

3. 22. 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.

4. 23. Gastroesephageal reflux and related motility disorders after esophageal atresia : a clinical study

   Författare :Madeleine Montgomery; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Esophageal atresia; tracheoesophageal fistula; gastroesophageal reflux; esophageal pH monitoring; respiratory function; gastric emptying; videomanometry STOCKHOLM 1997;

   Sammanfattning : The most common congenital malformation of the esophagus is esophageal atresia (EA) with or without tracheoesophageal fistula (TEF). Successful repair of EA does not ensure normal esophageal function. Disturbed esophageal motility and gastroesophageal reflux (GER) are often detected after repair of EA. LÄS MER

5. 24. The sites and mechanisms of postoperative insulin resistance

   Författare :Jonas Nygren; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Surgery; Insulin resistance; Glucosemetabolism; Glucose clamping technique; Gastric emptying; Immobilization; Preoperative fasting; ICF-I; Hospital stay; Stableisotopes ISBN 9;

   Sammanfattning : In Sweden with nine million inhabitants, 450,000 operations (outpatients excluded) are performed every year resulting in 2,250,000 treatment days in hospital. Surgical operations are part of the treatment for 44% of all patients admitted to hospital care occupying 24% of all hospital beds. LÄS MER

7. 25. Factors affecting body weight development and eating behaviour in patients on continuous ambulatory peritoneal dialysis treatment

   Författare :Anders Fernström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :CAPD; computed tomography; dual energy x-ray absorptiometry; electrogastrography; energy intake; ESRD; gastric emptying; HD; intraabdominal fat; protein-energy malnutrition; taste acuity; taste buds;

   Sammanfattning : Continuous ambulatory peritoneal dialysis (CAPD) and hemodialysis (HD) have different metabolic effects in dialysis patients, since absorption of intraperitoneal glucose implies an additional energy source in CAPD patients. In spite of this, protein-energy malnutrition is known to occur frequently, both in patients on hemodialysis and in patients on CAPD, and an association with increased morbidity and mortality is well established.
