  2. 1. Qualitative and Quantitative Assessment of Cytochromes P450 mRNA in Human : Studies in the Liver, Blood and Gastrointestinal Mucosa

    Author : Mari Thörn; Lars Lööf; Anders Rane; Ellen Vinge; Uppsala universitet; []
    Keywords : Medical sciences; cytochrome P450; CYP1A2; CYP1B1; CYP2E1; CYP3A4; CYP3A5; P-gp; gene expression; RT-PCR; liver; blood; gastrointestinal mucosa; MEDICIN OCH VÅRD; MEDICINE; MEDICIN;

    Abstract : Drugs and other foreign compounds must often be metabolised before they can be excreted from the body. One enzyme system that is responsible for this is the cytochrome P450 gene family (CYP). READ MORE

  4. 2. Involvement of the immune system in phytohaemagglutinin-induced structural and functional precocious maturation of the gut in young rats

    Author : Olena Prykhodko; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytokines; mucosa; development; Gastrointestinal tract; mammals; immune system; T-cells;

    Abstract : Mammals are born with an immature gastrointestinal (GI) tract that allows the uptake of the specific nutrients and bioactive macromolecules in the milk, especially the protecting maternal antibodies. Eventually during weaning, the intake of milk decreases while that of solid food increases, and the GI system undergoes prominent structural and functional changes adapting the young this dietary change.

  5. 3. The upper gastrointestinal tract in chronic alcoholics

    Author : Truls Hauge; Lund Medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alkaline phosphatase; mucosal bacterial growth; Helicobacter pylori; morphology; upper gastrointestinal endoscopy; chronic alcoholics; upper gastrointestinal tract; gamma-glutamyl transferase; neuropeptides.; Gastro-enterology; Gastroenterologi;

    Abstract : Background: Gastrointestinal symptoms such as dyspepsia, diarrhoea, and nausea are often seen in alcoholics. The causes are not clear. The stomach and upper small intestine are exposed to high alcohol concentrations. READ MORE

  6. 4. Gastrointestinal mucosal protective mechanisms : Mudolatory effects of Heliobacter pyroli on the gastric mucus gel barrier and mucosal blood flow in vivo

    Author : Christer Atuma; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; mucus gel layer; mucosal blood flow; mucus thickness; chronic infection; rat; platelet activating factor; mast cell; nitric oxide; nitric oxide synthase; ketotifen; intra-vital microscopy; microelectrode; laser-Doppler flowmetry; L-NNA; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : The gastrointestinal mucus gel layer and blood flow are two important mechanisms for protection at the pre-epithelial and sub-epithelial levels, respectively. Helicobacter pylori might circumvent these mechanisms and elicit a chronic inflammatory response with consequent ulcers in the stomach and duodenum. READ MORE

  7. 5. Gastrointestinal Disorders in Women

    Author : Rita Gustafsson; Gastroenterologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Abstract: This doctoral thesis has sought to clarify the influence of gender in gastrointestinal (GI) disorders. Women with different hormone profiles were investigated, their colonic microbiota was characterized, and the impact of lifestyle and risk factors for GI disease were examined. READ MORE
