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...

Focal epithelial hyperplasia (FEH) is a human papillomavirus (HPV)-induced alteration of the oral mucosa that presents with a clinically distinct appearance. While other HPV-infected lesions such as squamous papilloma, verruca vulgaris, and condyloma acuminatum involve the skin, oral mucosa, and genital mucosa, FEH occurs only in the oral mucosa. The affected oral mucosa exhibits multiple papul...

The object of this study was to characterize the synthesis and metabolism of platelet activating factor (PAF) by intestinal mucosa subjected to ischaemia-reperfusion injury. Canine intestinal mucosa produced 16:0-PAF, 18:0-PAF, and high levels of the corresponding lyso- PAF metabolites. Three h of intestinal ischaemia and ischaemia followed by 1 h of reperfusion did not affect the synthesis or ...

The purpose of this study was to analyze the stress and strain inside of the oral mucosa in partially-edentulous patients. The patient-specific finite element models of the mucosa and the bone were constructed using the CT images and in-vivo surface measurement during a continuous load. The mean initial shear modulus of 8.3 × 10(-5) (GPa) and the mean relaxation time of 503 (s) were determined ...

In order to compare delayed-type hypersensitivity (DTH) among different exposure sites, we evaluated the sensitization potency of mercuric chloride (HgCl(2)) via exposure to the skin, or oral or esophageal mucosa using the mouse ear swelling test. Furthermore, we investigated in vitro splenocyte proliferation reaction and cytokine profile in HgCl(2)-exposed and control mice. Sensitization with ...

OBJECTIVE Epithelial wound repair assures the recovery of the epithelial barrier after wounding. During wound healing epithelial cells migrate to cover the wound surface. For healing of skin wounds the skin keratinocytes can be replaced by oral mucosa epithelial cells grown in vitro. The presented experiments were carried out in order to compare the proliferation, morphology, and migration betw...

To assess the possibility that Campylobacter pylori might colonise heterotopic gastric mucosa a detailed histological review of 69 cases of Meckel's diverticula resected over 17 years was undertaken. Twenty three were resected incidentally while 46 were excised as the suspected cause of symptoms. Gastric mucosa was found in 13 diverticula (19%), 10 from the symptomatic group and three from the ...

 Results. Over past 10 years, proportion people underwent treatment mucosa has decreased, relative to total number admitted ...

Carlos Lima et al. who are pioneers in this field reported their clinical pilot study of olfactory mucosa transplantation for chronic spinal cord injury. They showed the safety and feasibility of it. Olfactory mucosa contains the olfactory ensheathing cells and neural stem cells. Recent studies have demonstrated the potential therapeutic role of both cells in spinal cord injury. We have already...
