Immunoglobulin containing cells in rectal and sigmoid colonic mucosa in endoscopically obtained biopsies from 10 patients with ulcerative colitis and 10 patients with Crohn's disease were studied, using an indirect immunoperoxidase technique. These findings were compared with the immunoglobulin containing cell number in colonic biopsies from 10 control patients with no evidence of colitis. In b...

Most patients with early esophageal cancer restricted to the mucosa may be offered endoscopic therapy, which is similarly effective, less invasive and less expensive than esophagectomy. Selection of appropriate relevant treatment and therapy methods should be performed at a specialized center with adequate facilities. The selection of an endoscopic treatment method for high-grade dysplasia and ...

The long chain fatty acid composition of phospholipids in colonic mucosa was determined by high performance liquid chromatography in nine patients with active ulcerative colitis and eight healthy controls. The arachidonic acid composition was 12.5 +/- 1.4 mol % (mean +/- 2 SEM) in the inflamed colonic mucosa from the patients with active ulcerative colitis and 6.8 +/- 1.2 mol % in the intact mu...

Light microscopy, scanning and transmission electron microscopy were used to study the anterior intestine of the sea bass Dicentrarchus labrax L., involved in lipid absorption. In the first part of the study, intestinal morphology of control feral fishes was described and lipid absorption through the intestinal mucosa was defined by comparing starved and fed individuals. In the second part, sim...

Early esophageal cancer is defined as a tumor invading the mucosa with or without lymph node or distant organ metastasis. In the current guidelines for early esophageal cancer, absolute indication for endoscopic resection include lesions limited to the epithelium or lamina propria mucosa not exceeding two-thirds of the circumference, and relative indications include lesions limited to the muscu...

The mechanical properties and structure alteration (e.g., layer morphology thickness) of the oesophagus wall can reflect its pathological conditions. Hence, quantitative measurement above-mentioned play a significant role in aiding disease diagnosis clinical application. As fast non-invasive imaging modality, Optical coherence tomography (OCT) vibrational elastography provide high resolution (&...

abstract  hypercementosis is identified by an excessive, non-neoplastic deposition of radicular cementum and is mostly presented as a solitary lesion or in rare cases as a multiple type. it usually occurs in the premolar and molar region of mandible with no sex predilection. in this paper, we reported a 57-year-old female patient with multiple radiopaque lesions affecting right maxillary second...

Gross and histological lesions caused by an intestinal parasite were described in three capybaras. The parasites presented a mean length of 14 mm and width of 7 mm, were round to oval or piriform, reddish and pedunculated, and adhered strongly to the mucosa of the large intestine. The intestinal mucosa at the parasite attachment site presented loss of surface epithelium and most glands, with re...

Citrobacter rodentium is a classically noninvasive pathogen of mice that is similar to enteropathogenic Escherichia coli (EPEC) in man. Following oral infection of young mice, the organism colonizes the distal colon, and within 1 week the colonic mucosa doubles in thickness and there is massive epithelial cell hyperplasia. Since T-cell responses in mouse models of inflammatory bowel disease (IB...

We read with interest the case of filiform polyposis (FP) associated with diverticulosis in the absence of inflammatory bowel disease.1 We would like to report herein an unusual presentation of ulcerative colitis as isolated filiform polyposis. A 72-year-old male patient was referred to us on March 2010 due to diarrhea of 12 months' duration and progressive 10-kg weight loss. The otherwise heal...
