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

    Author : Ying Sun; Göteborgs universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Role of Melatonin, Neuropeptide S and Short Chain Fatty Acids in Regulation of Duodenal Mucosal Barrier Function and Motility

    Author : Wan Salman Wan Saudi; Markus Sjöblom; Olof Nylander; Mark Berner-Hansen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 51Cr-EDTA; rat; in vivo; duodenum; enteric nervous system; paralytic ileus; parecoxib; bicarbonate secretion; motility; ethanol; HCl; melatonin; neuropeptide S; short chain fatty acids; chemosensing; Physiology; Fysiologi;

    Abstract : The duodenal epithelium is regularly exposed to HCl, digestive enzymes, bacteria and toxins, and sometimes also to ethanol and drugs. The imbalance of aggressive factors in the intestinal lumen and mucosal barrier function increases the risk of tissue injury and inflammation. READ MORE

  5. 3. Colonic pouch anastomosis after rectal excision for cancer

    Author : Olof Hallböök; Neil J. M. Mortensen; Linköpings universitet; []
    Keywords : Total mesorectal excision; low anterior resection; colonic pouch; coloanal anastomosis; neorectum; quality of life; laser-Doppler flowmetry; gut peptides; anorectal physiology; MEDICINE; MEDICIN;

    Abstract : Anastomoses at the level of the pelvic floor will become increasingly more common in rectal cancer surgery when total mesorectal excision is used as a standard procedure to obtain local mdicality. A consequence of such low anastomoses is increased risk of healing disturbances and poor distal bowel function, The aim of this thesis was to focus on reconstruction after total mesorectal excision.

  6. 4. lnvestigating intestinal smooth muscle dysfunction in the 6-OHDA rat model of Parkinson's disease

    Author : Maria del Pilar Murillo; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intestinal motility; smooth muscle; enteric nervous system; dopamine neurodegeneration;

    Abstract : The neurodegenerative progression of the nigrostriatal pathway in Parkinson’s disease (PD) entails the appearance of motor and nonmotor symptoms. Nonmotor symptoms are common, having a negative impact on the quality of life of patients living with PD. READ MORE

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

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

    Abstract : 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.
