  1. 1. The Duodenal Mucosal Bicarbonate Secretion Role of Melatonin in Neurohumoral Control and Cellular Signaling

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Markus Sjöblom; Uppsala universitet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; alkaline secretion; central nervous system; duodenal enterocyte; duodenal ulcer; duodenum; enterochromaffin cell; human; intraarterial; intracellular calcium; intracerebroventricular; melatonin; rat; vagal nerve; Fysiologi; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi;

    Sammanfattning : The duodenal lumen is exposed to aggressive factors with a high potential to cause damage to the mucosa. Bicarbonate secretion by the duodenal mucosa is accepted as the primary important defense mechanism against the hydrochloric acid intermittently expelled from the stomach. LÄS MER

  2. 2. Mucosal T-cell and cytokine responses in Helicobacter pylori-infected duodenal ulcer patients

    Detta är en avhandling från Göteborg

    Författare :Erika Strömberg; Göteborgs universitet.; Gothenburg University.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; mucosal immunology; antrum; duodenum; duodenal ulcer; asymptomatic; epithelial cells; cytokines; T cells;

    Sammanfattning : Helicobacter pylori colonizes the human stomach and areas of gastric metaplasia in the duodenum. The bacterium is the major cause of chronic active gastritis and peptic ulcer disease and is a risk factor for the development of gastric adenocarcinoma and lymphoma. LÄS MER

  3. 3. Complications to peptic ulcer and peptic ulcer surgery

    Detta är en avhandling från Department of Surgery, Clinical Sciences Lund, Lund University

    Författare :Kristina Åhsberg; Lunds universitet.; Lund University.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Long term effects after peptic ulcer surgery still exert an influence on some patient groups. Partial gastrectomy increases the risk of gastric carcinoma more than 20 years after surgery and enterogastric reflux is regarded as the main ethiological factor. LÄS MER

  4. 4. Regulatory CD4+FOXP3+ T cells in Helicobacter pylori-induced disease

    Detta är en avhandling från Department of Surgery, Clinical Sciences Lund, Lund University

    Författare :Bert Kindlund; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regulatory T cells; Helicobacter pylori; duodenal ulcer; gastric cancer; FOXP3;

    Sammanfattning : Helicobacter pylori colonize the gastric or duodenal mucosa of approximately half of the worlds’ population. Although most individuals are asymptomatic, H. pylori infection cause peptic ulcers or gastric cancer in 10-15 % and 1-2 %, respectively, of the infected individuals. LÄS MER

  5. 5. Helicobacter pylori interference with the L-arginine/NO pathway in the upper gut

    Detta är en avhandling från Göteborg

    Författare :Charlotte Von Bothmer; Göteborgs universitet.; Gothenburg University.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acid; bicarbonate; duodenal ulcer; Helicobacter pylori; host defence; mucosa; nitric oxide; nitric oxide synthase;

    Sammanfattning : Helicobacter pylori causes chronic gastritis and sometimes peptic ulcers but the pathogenesis is not fully understood. H. pylori-infected individuals with duodenal ulcer have an impaired duodenal mucosal bicarbonate secretion (DMBS) in response to acid. NO is an important signalling molecule in the body. LÄS MER
