Background and Aim: Lichen planus is an inflammatory autoimmune mucocutaneous disease. Stimulation of T cells and antigen-presenting cells (APCs), such as dendritic cells, mediates apoptosis of keratinocytes and basement membrane destruction. The aim of this study was to investigate the expression of one of the immune cell markers (CD86) in erosive oral lichen planus. Materials and Methods: In...

Microsatellite instability (MI) and K-ras oncogene mutation have been widely used as biomarkers of genetic changes in colorectal cancer (CRC). Each of these biomarkers was independently found in normal-appearing colonic mucosa at stages preceding the development of CRC, albeit at a relatively low incidence. To assess the potential value of combined MI and K-ras mutation analysis in the detectio...

Colorectal mucosa from patients with colorectal carcinoma was compared with rectal mucosa from a control group. It was found that the LDH isoenzyme pattern of uninvolved mucosa proximal and distal to the carcinoma differed from that of normal tissue and resembled that of carcinoma tissue except in the case of the uninvolved mucosa proximal to the carcinoma of the sigmoid colon, which did not di...

The distribution of basophiloid cells in nasal mucosa was examined both in the patients of nasal allergy and normal controls . Basophiloid cells were stained in alcian blue (P .H. 5.8) with 0.4M MgCl2. 1 ) The basophiloid cells in the nasal mucosa of allergic patients were far outnumbered those of normal controls. 2) The basophiloid cells in the epithelial layer were very few in normal controls...

OBJECTIVES To investigate the expression and distribution of glycoprotein 340 (gp340), a secretory glycoprotein, in normal human sinus mucosa and inflammatory sinus mucosa and evaluate the possible effects of gp340 on the development of chronic sinusitis. Glycoprotein 340 was identified as a key element in the innate host defense mechanism on many mucosal surfaces and is directly involved in de...
