Portal hypertensive (PHT) gastric mucosa increases susceptibility to injury and delayed mucosal healing. It is possible that nitration of ERK by peroxynitrite might alter MAPK (ERK) signaling in PHT gastric mucosa, leading to delayed mucosal healing, since excessive nitric oxide production is implicated in PHT gastric mucosa and MAPK (ERK) signaling induces cell proliferation and leads to gastr...

Models for the pathogenesis of colorectal cancer tend to focus on the localized lesion, with less attention paid to changes in normal-appearing mucosa. Here we used two-dimensional gel electrophoresis and mass spectrometry to define patterns of protein expression in morphologically normal colonic mucosa from 13 healthy subjects, 9 patients with adenomatous polyps, and 9 with cancer. Tumor sampl...

Oxygen derived radicals contribute to tissue injury in inflammatory bowel disease. We measured the content of superoxide dismutase and metallothionein (two endogenous copper and zinc containing proteins involved in radical scavenging) in intestinal resection specimens from 29 patients with Crohn's disease and 12 patients with ulcerative colitis and compared the concentrations with those obtaine...

To contribute to early diagnosis and treatment of gastric ulcer of foals, we examined the gastric mucosa of healthy and affected foals using an endoscope. In healthy foals, the characteristic changes in the development of the squamous mucosa were seen mainly in the squamous mucosa, and maturation of the squamous mucosa in the greater curvature (GC-S) occurred more slowly than that of the squamo...

BACKGROUND The aim of this study was to evaluate gene expression profiles in unaffected colon mucosa and polyp tissue from patients with unifocal colon polyp to investigate the potential mucosa impairment in normal-appearing colon mucosa from these patients. MATERIAL AND METHODS Colon polyp patients were prospectively recruited. We obtained colon biopsies from the normal-appearing sites and pol...

The oral mucosa is a critical barrier tissue that harbors a series of distinct immune cell subsets. Immune surveillance in the oral mucosa is important for both local and systemic immunity because the oral cavity is a heavily utilized route of pathogen entry and also serves as site of pathogen propagation. Nonetheless, composition and phenotype of the lymphocyte pool in the oral mucosa have rem...

In the previous communication results were reported to show that the K / C a ratio in carcinoma of the stomach was increased relative to that in the adjacent mucosa and relative to the mucosa of noncancerous stomachs. This increase was the result of elevated potassium and decreased calcium in the neoplasms. summarized in Table I. The average water content of mucosa and carcinoma was approximate...

INTRODUCCIÓN: El exantema mucocutáneo inducido por Mycoplasma (EMIM) es una entidad separada del síndrome de Stevens-Johnson(SSJ) y el eritema multiforme (EM), descrita principalmente en adolescentes la que predomina afectación mucosa sobre cutánea.OBJETIVO: Describir nuestra experiencia pacientes pediátricos afectos EMIM.MATERIALES Y MÉTODOS: Estudio descriptivo retrospectivo menores 14 años c...

Whole-body autoradiography of 3H-labeled aflatoxin B1 (AFB1) in adult C57BL mice pretreated with the glutathione (GSH)-depleting agent phorone showed accumulation of tissue-bound radioactivity in the nasal olfactory and respiratory mucosa, the mucosa of the nasopharyngeal duct, and the tracheal and esophageal mucosa, which was not seen in unpretreated adult mice. The altered distribution pictur...

oral mucosa can be affected in many systemic diseases such as chronic renal failure (crf). many metabolic and hematologic disorders develop in patients with crf which can also affect oral cavity. oral mucosa, teeth, salivary glands and jaw bones are affected. although hemodialysis can improve many of systemic features but the best treatment is renal transplantation. in addition to previous feat...
