Strains of Salmonella typhimurium were studied in the ligated rabbit ileal loop model to gain insight into the mechanisms whereby bacteria which invade the gastrointestinal mucosa evoke fluid exsorption. The organisms employed differed in various biologic attributes including the ability to invade the ileal epithelium, multiply within the mucosa, elicit an acute inflammatory reaction, and disse...

INTRODUCTION Oesophageal heterotopic gastric mucosa mostly presents in the upper part of the oesophagus. It is commonly under-diagnosed because of its localisation. AIM To expose the association between heterotopic gastric mucosa and endoscopic features of the upper gastrointestinal tract. MATERIAL AND METHODS A total of 1860 upper endoscopic examinations performed between January 2012 and ...

mast cells are related to certain gastrointestinal complaints. mast cell density has not been studied in cardio-esophageal region to the best of our knowledge. in this study we wanted to obtain an estimate of mast cell density in this region and compare it with mast cell density in antrum. from april 2007 till march 2010, we chose children (<14 years old) who underwent upper endoscopy and from ...

Background. Since gastrointestinal stromal tumor (GIST) is a mesenchymal submucosal tumor, the endosonographic, CT, and MRI features of gastric GISTs have been widely investigated. However, the GIST-bearing gastric mucosa status has not been reported. Objective. To characterize the GIST-bearing gastric mucosa status in terms of the degree of inflammation and atrophy, assessed endoscopically. Su...

Lipid peroxidation in vitro was tested by malonaldehyde production in gastrointestinal mucosa and compared with other tissues. It was observed that gastrointestinal mucosa was resistant to both non-enzymatic and enzymatic lipid peroxidation. This was due to the presence of an inhibitor of lipid peroxidation in the membranous fractions of intestinal mucosa. This inhibitor was capable of inhibiti...

BACKGROUND Mucosa-associated lymphoid tissue lymphomas can occur in various parts of the body, and half of mucosa-associated lymphoid tissue lymphomas occur in the gastrointestinal tract. Gastric mucosa-associated lymphoid tissue lymphoma is the most common lymphoma of the gastrointestinal tract and primary rectal mucosa-associated lymphoid tissue lymphoma is very rare. Because of the high radi...

barrett's mucosa is one of the most important diseases in upper gastrointestinal system that caused by gastroesophagus reflux. if left untreated, the disease will cause distal esophagus and gastric cardiaadenocarcinoma. the malignancy risk is very high in short segment barrett’s mucosa. therefore,lesion area segmentation can improve specialist decision for treatment. in this paper, we proposeda...

Mucosa Associated Lymphoid Tissue (MALT) lymphoma, accounting for about 5% of non-Hodgkin’s lymphoma, arises in a number of epithelial tissues, mostly in the gastrointestinal tract, respiratory tract, ocular adnexa, thyroid and salivary glands. MALT lymphoma primarily arising from the kidney is extremely rare. Here we report a case that was admitted to our institution due to left hydronephrosis...
