    Sammanfattning : The novel gastric hormone ghrelin was discovered by virtue of its ability to release growth hormone (GH) via interaction with the so-called GH-secretagogue receptor (GHS-R). Earlier only synthetic agents were known to bind with the GHS-R, hence, ghrelin is the first identified endogenous ligand. LÄS MER

  3. 2. SODIUM/IODIDE SYMPORTER-NIS Abundant and Important in Gastric Mucosa

    Författare :Malin Josefsson; Neurogastroenterologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ussing chamber; MNNG; gastric iodide secretion; ouabain; gastric cancer; sodium perchlorate; gastric NIS; bile duct cancer; Sodium iodide symporter;

    Sammanfattning : ABSTRACT Background: Iodine is essential for development and growth as a constituent in thyroid hormones. Biological mechanisms for iodide uptake and concentration are very important, espe-cially as iodine is a relatively scarce element. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Helicobacter pylori and Gastric Protection Mechanisms : An in vivo Study in Mice and Rats

    Författare :Johanna Henriksnäs; Lena Holm; Lars Engstrand; Erik Persson; Lars Fändriks; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; mucus gel layer; mucosal blood flow; mucus thickness; intra-vital microscopy; laser-Doppler flowmetry; pH-sensitive microelectrode; nitric oxide; Helicobacter pylori; bicarbonate secretion; mouse model; Fysiologi; Physiology; Fysiologi;

    Sammanfattning : The stomach is frequently exposed to hazardous agents and to resist this harsh environment, several protective mechanisms exist. Of special interest is the gastric pathogen Helicobacter pylori which causes gastritis, ulcers and cancer but the mechanism leading to these diseases are still unclear. However it is very likely that H. LÄS MER
