  1. 1. Intestinal permeability : a parameter of mucosal dysfunction

    Author : Pål Lundin; Lund University.; Lunds universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peptide; N-acetylcysteine; Medium-chain glyceride; Mannitol; Macromolecules; Lipid; Kinetics; In vivo; In vitro; In situ; Intestine; Injury; Inflammation; HLA-B27; HCl; Epithelium; Enhancer; dDAVP; 51Cr-EDTA; BSA; Absorption; Albumin; Permeability; Animal physiology; Djurfysiologi;

    Abstract : The gastrointestinal tract has two opposing functions; to absorb nutrients and electrolytes, and to act as a barrier towards hazardous and non-nutritional substances. In the present thesis the barrier function of the gastrointestinal tract was studied in animal models in vivo, in situ and in vitro. READ MORE

  2. 2. Nitrate, Nitrite and Nitric Oxide in Gastric Mucosal Defense

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Joel Petersson; Uppsala universitet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dietary nitrate; mucus gel layer; mucosal blood flow; mucus thickness; laser-Doppler flowmetry; mucosal damage; intra-vital microscopy; mucosal permeability; ODONTOLOGY Physiology; ODONTOLOGI Fysiologi;

    Abstract : The human stomach normally contains high levels of bioactive nitric oxide (NO). This NO derives from salivary nitrate (NO3-) that is converted to nitrite (NO2-) by oral bacteria and thereafter non-enzymatically reduced in the acidic gastric lumen to NO. READ MORE

  3. 3. Gastrointestinal Permeability and Motility in Inflammatory Bowel Disease

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anas Kh. Al-Saffar; Uppsala universitet.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gastrointestinal motility; intestinal permeability; Mucosal; Ghrelin; Medicinsk vetenskap; Medical Science;

    Abstract : Synchronized motility, permeability and secretory (hormones and enzymes) events are integral to normal physiology. Smooth muscle syncytium operates with enteric nervous system (ENS) and endocrine signalling to accommodate, mix and control passage of ingested materials. READ MORE

  4. 4. Gastric gland luminal pressure and mucosal protection : An in vivo study in the anesthetized rat

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ingrid Synnerstad; Uppsala universitet.; [1997]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; acid secretion; bicarbonate; epithelial cell surface pH; gastric gland; muscularis mucosa; micropuncture; mucosal blood flow; mucus gel thickness; omeprazole; permeability; prostaglandins; ranitidine; rat; Fysiologi och anatomi; MEDICINE Physiology and pharmacology; MEDICIN Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : The driving force for creation of channels in gastric mucus, for acid and pepsin transport, ismost probably the hydrostatic pressure generated within the gastric gland lumen. The aim ofthis study was to investigate the origin and regulation of the glandular pressure. READ MORE

  5. 5. Gut peptides in gastrointestinal motility and mucosal permeability

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Md. Abdul Halim; Uppsala universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gut regulatory peptides; Neuropeptides; Gastrointestinal mucosal permeability; Gastrointestinal motility; GLP-1; NPS; ROSE-010;

    Abstract : Gut regulatory peptides, such as neuropeptides and incretins, play important roles in hunger, satiety and gastrointestinal motility, and possibly mucosal permeability. Many peptides secreted by myenteric nerves that regulate motor control are also produced in mucosal epithelial cells. READ MORE
