lichen planus (lp) is a chronic inflammatory disease of probable immune-based etiology. the pathogenesis of lp is unclear, but apoptotic changes in epidermal (epithelial) cells have been reported. destruction of the basal cell layer is observed and many changes in cell proliferation, cell repair and cell death occur in the injured mucosal epithelium. the aim of this study was to evaluate and co...

Multiple particle-tracking techniques were used to quantify the thermally driven motion of ensembles of naked polystyrene (0.5 µm diameter) microbeads in order to determine the microrheological characteristics around the gut mucosa. The microbeads were introduced into living ex vivo preparations of the wall of the terminal ileum and proximal colon of the brushtail possum (Trichosurus vulpecula)...

CD36 is a transmembrane protein that is involved in the recognition of certain amphiphilic molecules such as polar lipids in various tissues and body fluids. So far, CD36 homologues in insects have been demonstrated to be present on the surface of olfactory dendrites and to participate in the perception of exogenous compounds. However, little is known about the relationship between CD36 and mam...

Solitary rectal ulcer syndrome (SRUS) is an uncommon poorly understood benign disorder of defecation. SRUS may simulate other disorders such as inflammatory bowel disease andneoplasms. Histopathological analysis forms the cornerstone of diagnosis for SRUS.Key histological features include fibromuscular obliteration of the lamina propria with splaying of the muscularis mucosae upward between the...

esophagus having different tissues has a special role in the gastrointestinal tract. among different species, layers of the esophagus, have a substantial difference. also, diameter of esophagus varies in different parts of it.the information of histological structure of rabbit and guinea pig esophagus is still incomplete. therefore, the present study was conducted. therefore, for review and com...

PURPOSE The purpose of this study was to clarify the "healing capacity" of wounds of the oral mucosa in comparison to those of the skin, and to evaluate the wound healing mechanism of oral mucosa using a cytobiological approach from the aspect of energy metabolism in oral keratinocytes. MATERIALS AND METHODS Samples of epidermal and oral keratinocytes collected at surgery and of cultured oral...

background there is a dearth of epidemiologic studies that provide important information to understand the incidence, prevalence and severity of oral lesions in patients with tuberculosis (tb). objectives this study aimed to determine the prevalence of oral mucosal lesions and adverse habits among hospitalized tb patients. patients and methods the study was conducted on all the tb patients (n =...

The expression of several markers of epithelial cell proliferation was analyzed to establish baseline data for future chemoprevention studies of oral premalignant lesions. Punch biopsies (n = 60) from three different sites of oral mucosa (bucca, lateral tongue, and the floor of the mouth) were obtained from 20 normal donors of both sexes. After formaldehyde fixation and paraffin embedding, immu...

background: the health risks of crack cocaine smoking on the oral mucosa has not been widely researched and documented. objective: the purpose of this study was to analyze the proliferative activity of oral epithelial cells exposed to crack cocaine smoke using silver nucleolar organizer region (agnor) staining. methods: oral smears were collected from clinically normal-appearing buccal mucosa b...
