    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

    Abstract : The duodenal epithelium secretes bicarbonate ions and this is regarded as the primary defence mechanism against the acid discharged from the stomach. For an efficient protection, the duodenum must also function as a sensory organ identifying luminal factors. READ MORE

  5. 15. Luminal Hypotonicity and Duodenal Functions An Experimental Study in the Rat

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Liselotte Pihl; Uppsala universitet.; [2007]
    Keywords : Physiology; luminal alkalinization; mucosal permeability; osmolality; cyclooxygenase-2; rat; duodenum; jejunum; motility; enteric nervous system; Fysiologi;

    Abstract : After drinking water, the fluid quickly leaves the stomach thereby creating a hypotonic luminal environment in the duodenum. This in turn constitutes a potential threat to the integrity of the duodenal epithelium. It therefore seems highly likely that luminal hypotonicity activates physiological mechanisms that aim to increase luminal osmolality. READ MORE
