  1. 1. Parietal cell regeneration in rat gastric mucosal wounds a quantitative light and electron microscopical study

    University dissertation from Umeå : Umeå universitet

    Author : Håkan Blom; Umeå universitet.; [1982]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rat; gastric mucosa; gastric wounds; parietal cells; re­generation; pyloroplasty; truncal vagotomy; antrectomy; pen­tagastrin; cimetidine; carbacholine; stereology; light microscopy; electron microscopy; pH-studies;

    Abstract : The aims of the study were to obtain a method with which it would be possible to produce standardized wounds in the gastric mucosa, and to follow the regeneration of the acid producing parietal cells in those lesions during different experimental conditions. Quantitative methods applied to light and electron microscopy were used. READ MORE

  3. 3. 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

  4. 4. Helicobacter pylori and Gastric Protection Mechanisms An in vivo Study in Mice and Rats

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johanna Henriksnäs; Uppsala universitet.; [2005]
    Keywords : 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; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi;

    Abstract : 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. READ MORE

  5. 5. Acid transport through gastric mucus A study in vivo in rats and mice

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mia Phillipson; Uppsala universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; gastric acid; pH-sensitive microelectrode; mucus; mucosal blood flow; nitric oxide; intravital microscopy; laser Doppler flowmetry; Fysiologi; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi; Physiology; fysiologi;

    Abstract : The gastric mucosa is frequently exposed to endogenously secreted hydrochloric acid of high acidity. Gastric mucosal defense mechanisms are arranged at different levels of the gastric mucosa and must work in unison to maintain its integrity. READ MORE
