Injury or bulging subepithelial mucosal lesions are covered with normal mucosa, usually asymptomatic. Most are diagnosed in radiology or endoscopy, which may correspond to any layer of the body wall (intramural) or non-belonging to the wall (extramural). This article describes studies for analysis of endoscopic ultrasonography (EUS) as a diagnostic method with high accuracy on the finding of su...

OBJECTIVES To highlight the most characteristic histopathological findings of oral lichen planus and their correlation with the clinical manifestations and forms. STUDY DESIGN We performed a retrospective study of 50 biopsied and diagnosed cases of oral lichen planus obtained over a period of 11 years, spanning from May 1998 to April 2009. We analyzed the age and sex of the patient, type of l...

The spectral reflectance of the colon is known to be affected by malignant and pre-malignant changes in the tissue. As part of long-term research on the derivation of diagnostically important parameters characterizing colon histology, we have investigated the effects of the normal histological variability on the remitted spectra. This paper presents a detailed optical model of the normal colon ...

The surface mucosa of the stomach and duodenum is frequently exposed to a potentially corrosive mixture of hydrochloric acid and pepsin and intraluminal pH is often between 1 and 2. Such acidity would be injurious to ordinary epithelia so that it is clear that mechanisms exist to protect the stomach and duodenum under normal circumstances. The notion that gastric mucus and non-parietal gastric ...

Helicobacter pylori is a gram negative microaerophilic spiral bacteria that was first identified by Warren and Marshall in 1983. It is found predominantly beneath the gastric mucus layer that lines the surface epithelium of the stomach and can colonize the gastric mucosa for years. Recent research suggests that Helicobacter pylori (H pylori) infection is a recognised cause of gastritis and pept...

linated nerve fibers and Schwann cells is found near blood capillaries in the lamina propria of the proventricular mucosa of the finch. At least two types of endocrine cells (type I and II) are present mainly in the lamina propria mucosae where they form a neuro-endocrine complex, but some cells of both types are also seen in the basal part of the epithelial layer like mammalian basal-granulate...

In the normal process of digestion, not only substances in solution are absorbed. Solid, undissolved particles in macrocorpuscular form, are "kneaded" into the mucosa during their passage through the digestive tract. These particles in the micrometer size range pass between the epithelial cells into the subepithelial layer. From here they are transmitted both by the lymph vessels and by the mes...
