  1. 6. 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. 7. Constipation : symptoms and findings in relation to structural and functional abnormalities

    Författare :Abdulhakim Glia; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :constipation; defecation; electromyography; gastrointestinal motility; immunchistochernistry; intestinal pseudo-obstruction; physiopathology; quality of life; transit time;

    Sammanfattning : The aim of this study was to increase the knowledge about functional constipation with special reference to symptoms analysis, laboratory investigations and histopathology findings. 155 consecutive patients with intractable constipation underwent anorectal manometry, electromyography (EMG), balloon expulsion test, colonic transit time, and defecography.

  5. 9. 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

  7. 10. Rectal prolapse, internal rectal intussusception and the ripstein rectopexy : a clinical, physiological and radiological study

    Författare :Inkeri Schultz; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Anal incontinence; constipation; procidentia; rectal prolapse; internal rectal intussusception; Ripstein s operation; rectopexy;

    Sammanfattning : The aim of these studies was to increase the knowledge about rectal prolapse and internal rectal intussusception, with special reference to bowel function and treatment with the Ripstein rectopexy. Results after the Ripstein rectopexy in 69 patients with rectal prolapse and in 43 patients with internal metal intussusception were evaluated. LÄS MER
