    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 tightly adherent monolayer of epithelial cells that line the luminal side of the intestine provides a dynamic and highly regulated barrier to the passive and active transport of ions, water and macromolecules. Cathecol-O-methyl transferase inhibition prevents tissue degradation of catecholaminesincluding dopamine and intracellular carbonic anhydrase activity is an important regulator of ion and water transport in the small intestine.

    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
