The blood group A determinant is carried by four basic carrier carbohydrate chains. This paper reports the expression of blood group A variants, as determined by immunohistology with highly specific monoclonal anti-A antibodies, in 18 adenocarcinomas of the distal colon, 4 specimens of normal proximal mucosa from group A persons, and 5 specimens of fetal colonic mucosa. Monoclonal antibodies di...

BACKGROUND Severe asthmatics are thought to have severer rhinitis than mild asthmatics. A pale nasal mucosa is a typical clinical finding in subjects with severe allergic rhinitis. OBJECTIVE The aim of this study was to investigate whether a pale nasal mucosa affects airflow limitations in the upper and lower airways in asthmatic children. METHODS Rhinomanometry, nasal scraping, and spirome...

Mast cell-derived chymase promotes inflammatory responses and tissue fibrosis. Although previous studies have reported changes in the number of mucosal mast cells in inflammatory bowel disease (IBD), the behaviour of chymase immunopositive mast cells has not been studied. In this study, we immunohistochemically investigated chymase immunopositive mast cells in the inflamed mucosa of IBD patient...

Osteonecrosis of the jaw (ONJ) is an adverse outcome associated to bisphosphonate treatment. However, it is not known whether the ONJ lesion originates in the bone, or whether it may initiate in the oral mucosa. The aim of our study was to evaluate the pattern of basal lamina of oral mucosa after bisphosphonate administration and to analyze the structural damage of the mucosa in ONJ patients, a...

Patients using obturator prostheses often present denture-induced stomatitis. In order to detect the presence of oral Candida albicans in patients with oronasal communications and to evaluate the effectiveness of a topical antifungal treatment, cytological smears obtained from the buccal and palatal mucosa of 10 adult patients, and from the nasal acrylic surface of their obturator prostheses we...

Comparison of Nucleus and Cytoplasm Diameter Buccal Mucosa Cells in Cigarette Smokers Nonsmokers: A Cytomorphometric Study using Feulgen Papanicolaou Stains

The oral cavity undergoes essential age-related changes involving the mucosa, dental and periodontal tissues, musculoskeletal system [...]

THE gastric mucous membrane is described as being disposed in three regions, known as the cardiac, fundic, and pyloric. These regions, although distinguished from one another by definite microscopic characters, yet merge gradually the one into the other, so as to present no well-defined lines of demarcation. The actual extent of each region varies in different animals. It has not been sufficien...

Sir, We thank Drs. Walker-Smith and Rossiter (1973) for their comments regarding abnormal mucosa in gastroenteritis, but feel constrained to reply to one or two points at this late stage. They reject the statement that single biopsy specimens provide reliable information about the degree of damage to duodenal mucosa on the basis that 3 cases biopsied serially showing 'a consistent trend towards...

Abstract Background Up to 30% of Crohn's Disease (CD) patients suffer from perianal fistula creating a high disease burden. Treating CD is challenging compared cryptoglandular fistula, which have significantly better wound healing response. Previous studies suggested epithelial mesenchymal transition as an inducer formation, markers were observed in tracts. However, most normal mucosa, thus dis...
