  1. 1. Tachykininergic and serotonergic control of the migrating motor complex : studies in rat and man

    Författare :Mikael Lördal; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Small intestinal motility; MMC; human; rat; tachykinins; serotonin; 5 hydroxytryptamine; substance P; neurokinin A.;

    Sammanfattning : Small bowel motility has been studied in rats and in humans by means of electromyography and manometry. The aim was to study the effects of mammalian tachykinins and 5 hydroxytryptamine(5-HT, serotonin) on small bowel motility, with special regard to the migrating motility complex (MMC), contractile force, and transit of small bowel contents.

  3. 2. Sensory and secretory responses to intestinal distension; implications for the pathophysiology of the irritable bowel syndrome

    Författare :Marie Larsson; Göteborgs universitet; []
    Nyckelord :irritable bowel syndrome; secretion; transmucosal potential difference; migrating motor complex; colorectal distension; visceral sensitivity; colitis; enteric nervous system; rat; mouse;

    Sammanfattning : Irritable bowel syndrome (IBS) is a common gut disorder, characterized by abdominal pain and/or discomfort associated with disturbed bowel habits. The pathophysiology of IBS is complex and still largely unknown, although visceral hypersensitivity is frequently associated with the disease. LÄS MER

  4. 3. Adrenergic control of small intestinal motility and blood flow : an experimental study in rat and man

    Författare :Mikael Thollander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :clonidine; computerized recording; intestinal blood flow; isoprenaline; laser Doppler flownretry; manometry; migrating motor complex; oxymetazoline; propranolol; small intestine;

    Sammanfattning : Small intestinal motility in the fasted state is characterized by migrating motor complexes (MMCs). Both animals and man exhibit the MMC, which consists of periods of regular contractions, i.e. activity fronts, that migrate along the length of the small bowel and alternate with periods of quiescence.

  5. 4. Gastroduodenal epithelial transport in patients with cystic fibrosis

    Författare :Karin Edshage Hallberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cystic fibrosis; CFTR; intestinal motility; gastric secretion; IgA; Ussing chamber; intestinal permeability; genotype;

    Sammanfattning : Cystic fibrosis (CF) is an inherited disease where respiratory failure due to chronic lung infection is the major cause of death. A defective protein, cystic fibrosis transmembrane conductance regulator (CFTR) alters chloride epithelial transport. LÄS MER

  7. 5. Gastric acid secretion and gut peptides : mechanisms involved in inflammatory response

    Författare :Tobias Rudholm Feldreich; Karolinska Institutet; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The regulation of gastric acid secretion is complex and involves endocrine, paracrine, and neurocrine mechanisms. Among these, the interconnecting cross-talk between different gut peptides is an important part in the control of acid secretion. LÄS MER
