A 22 year-old man without previous diseases came to emergency room for purpuric cutaneous lesions at elbows, tibial surfaces and feet appeared eight days before preceded by a selflimited catarrhal process. Following the patient was examined for abdominal pain, vomit, diarrhea and knees, ankles and wrist arthritis. The physical examination did not show others data of particular interest. Laborat...

The mast-cell distribution in the digestive tract of the rat, dog, cat, and guinea-pig was studied. In the rat mast-cells were present in the tongue, oesophagus, and forestomach, but practically absent from the glandular stomach, duodenum, ileum, and rectum. In the other species, mast-cells were numerous throughout the whole of the digestive tract, presenting a large individual variation. In th...

BACKGROUND In patients with chronic diarrhea, colonoscopy may identify inflammatory causes or some occult disease, and also can show a normal mucosa. Serial biopsies of intestinal mucosa can be useful for a differential diagnosis, and to modify the treatment. AIM To evaluate whether the biopsies performed in patients with chronic diarrhea and a normal colonoscopy contribute to the differentia...

We would like to report on a case that could represent the first endoscopic presentation of ulcerative colitis as a focal colitis of some isolated colonic folds. A 46year old asymptomatic male underwent a surveillance endoscopy for adenomatous polyps in the past. In the sigmoid part of the colon one sessile adenomatous polyp of 6mm was removed by snare polypectomy. Surprisingly endoscopy reveal...

The mechanism by which baicalin modulated the expression of inducible nitric oxide synthase (iNOS) and nitric oxide (NO) in the mucosa of distal ileum was investigated in a rat model of acute endo-toxemia induced by intraperitoneal injection of bacterial lipopolysaccharide (LPS). The experiment demonstrated that LPS upregulated iNOS mRNA and protein expression as well as NO produc-tion (measure...

The digestion of dietary fibers is a major function of the human intestinal microbiota. So far this function has been attributed to the microorganisms inhabiting the colon, and many studies have focused on this distal part of the gastrointestinal tract using easily accessible fecal material. However, microbial fermentations, supported by the presence of short-chain fatty acids, are suspected to...

Sucrose, unlike the other common disaccharides, maltose and lactose, has been reported to be absorbed poorly from jejunum in man. Using a single-lumen tube technique and giving a carbohydrate-protein-fat meal with a single disaccharide as the source of carbohydrate, Dahlqvist and Borgstr6m (1) reported efficient absorption of lactose and maltose from human jejunum but minimal absorption of sucr...

Different challenges are being applied in the poultry industry order to protect animal health and increase immunity production. The supplementation of microbial phytase is essential terms both reducing inorganic rate contributing absorption other minerals. In this study, a newly isolated was added at different concentrations diet together with calcium (Ca$^{2+}$) available phosphorus (AP), effe...

Secretory immunoglobulin A (SIgA) and immunoglobulin G (IgG) antibody-secreting cells (ASCs) are two important cell types in the mucosal immune system. This study aimed to explore the distribution of these ASC populations in the small intestine of Bactrian camels of different ages. Twenty-four Alashan Bactrian camels were divided into the following four age groups: young (1-2 years), pubertal (...

OBJECTIVES Preventing postoperative recurrence after ileocolonic resection (ICR) for Crohn's disease (CD) is challenging. Defining the disturbances of the microbial composition and community structure after ICR and their link with early disease recurrence is crucial. DESIGN Microbiota composition (fingerprinting and 16S rDNA sequencing) and community structure (correlation networks of bacteri...
