Haemorrhagic mucosal lesions are produced during intestinal ischaemia and after reperfusion probably mediated by oxygen radicals. Oxygen radicals react with cell membrane lipids and induce cell damage by peroxidation and induce accumulation of polymorphonuclear leucocytes in the tissue. The aim of the study was to elucidate the involvement of polymorphonuclear leucocytes in post-ischaemic intes...

matory lesions in the lower gastrointestinal tract including polyps, masses and ulcers that are characterized by elongated and distorted glands surrounded by proliferation of smooth muscle fibers from the muscularis mucosae. The term “prolapsing mucosal polyp” was first described by Franzin et al in 1985 as a new entity of benign colorectal polyp. They reported that these benign colonic lesions...

BACKGROUND Pemphigus vulgaris (PV) is a rare autoimmune blistering disease of the skin and mucous membranes. It varies in its clinical profile and epidemiologic characteristics in different parts of the world. OBJECTIVE To determine the clinical features of PV in Iran in a prospective manner. METHODS The study included 140 patients with newly registered PV attending our dermatology clinic b...

Disturbance of the microcirculation and generation of reactive oxygen species are crucial in producing acute gastric mucosal lesions (AGML). To understand the protective mechanism against mucosal injury and oxidative stress in the stomach, we investigated sequential expression and localization of a product of lipid peroxidation and a chemical mediator of the oxidative response array, 4-hydroxyn...

BACKGROUND How smokeless tobacco contributes to non-neoplastic oral diseases is unclear. It certainly increases risk of oral mucosal lesions, but reviewers disagree as to other conditions. In some areas, especially South-East Asia, risk is difficult to quantify due to the many products, compositions (including non-tobacco ingredients), and usage practices involved. This review considers studies...

Few reports have been published highlighting oral findings in COVID-19 patients. Since the outbreak of recent pandemic caused by SARS-CoV-2, it is important to illustrate very near future how recurrent these are symptomatic patients contrast those asymptomatic ones, as there multiple reported. This case study a new combination two from India, one symptomatic, and other asymptomatic. Cases prese...

A 24 year old woman with bilateral oral white patches was referred to dermatology clinic. Her chief complaint was mouth burning. Pathological report of cut section biopsy from oral mucosa was in favor of lichen planus. Intralesional corticosteroid injection and it's subsequent systemic administration 30 mg/ daily for one month showed no improvement. Therefore a combination of systemic corticost...
