BACKGROUND Birch pollen allergic patients frequently experience gastrointestinal upset accompanied by a local allergic inflammation in the small intestine especially during the pollen season. However, it is not known if the GI pathology is connected to the subjective symptoms of the patient. The objective of this study was to evaluate the immune pathology of the duodenal mucosa and the serum Ig...

BACKGROUND Glutathione (GSH) and the cytosolic glutathione S-transferases (GSTs) protect the gastrointestinal mucosa against the toxic effects of a wide variety of compounds, such as reactive oxygen species and electrophiles. AIMS We wished to investigate the distribution along the upper gastrointestinal mucosa and the influence of clinical variables on components of the GSH system to learn m...

the peutz-jeghers syndrome is characterized by an association of gastrointestinal polyposis with rnelain spots on oral mucosa, lips, and skin. this symdrorne is inherited as a simple mendelian autosomal dominant trait. intussusception is by far the most common complication. although these polyps are widely regarded as hamartomas and rarely undergo malignant change, they have been reported to be...

DESCRIPTION A 27-year-old woman presented to the medicine outpatient clinic with easy fatiguability and breathlessness on exertion since 2 months. She also complained of sore oral mucosa and was unable to swallow large morsels of food. Physical examination revealed angular cheilitis and pigmentation of the oral mucosa, severe pallor, koilonychias (figure 1), large volume pulse and a haemic murm...

Ghrelin is 28-amino-acid peptide that was discovered from the rat and human stomach in 1999. Since the discovery of ghrelin, various functions of ghrelin, including growth hormone release, feeding behavior, glucose metabolism, memory, and also antidepressant effects, have been studied. It has also been reported that ghrelin in the gastrointestinal tract has an important physiological effect on ...

Excluding parenteral transmissions, virtually all vertical and homosexual transmission of human immunodeficiency virus type 1 (HIV-1) occurs via the gastrointestinal tract. Cellular routes implicated in the translocation of virus across the epithelium include M cells, dendritic cells, and epithelial cells. Intestinal epithelial cells express CCR5 and can selectively transfer CCR5-tropic HIV-1, ...

Feeding of neonates with artificial milk formulas delays the maturation of the gastrointestinal mucosa. Na-butyrate has a complex trophic effect on the gastrointestinal epithelium in adults. The present study aimed to determine the effect of milk formula supplementation with Na-butyrate on the gut mucosa in neonatal piglets. Sixteen 3 day old piglets were randomly divided into two groups: contr...
