Expression of Cytokeratin 19 in the epithelial cell of Azo-exposed buccal mucosa
Background: Azo is a synthetic dye used in batik industries. It can be toxic to the tissue when exposed via inhalation, swallowing, or direct contact. Expression of cytokeratin will change in hyperplastic and cancer of the oral mucosa. Expression of Cytokeratin 8, 18, 19 is strong in the epithelial cells that undergo excessive hyperproliferation and oral mucosal changes in le...
متن کاملComparison of Expression of Cytokeratin 7 on Epithelium of Nasal Polyps and Mucosa of Chronic Rhinosinusitis
Background and Objective: Nasal polyp is the most common benign mass of the nasal cavity and it is originated from nasal cavity or sinuses. Cytokeratins (CK) are intermediate filament proteins that provide mechanical support in epithelial cells. The purpose of this study was to compare the expression of cytokeratin 7 in epithelium of nasal polyps and nasal mucosa in chronic rhinosinusitis. Mate...
متن کاملEpithelial Dysplasia in Oral Cavity (Review Article)
Among oral lesions, we encounter a series of malignant epithelial lesions that go through clinical and histopathologic processes in order to be diagnosed. Identifying these processes along with the etiology knowledge of these lesions is very important in prevention and early treatments. Dysplasia is the step preceding the formation of squamous cell carcinoma in lesions which have the potential ...
متن کاملArginase activity determination. A marker of large bowel mucosa proliferation.
Arginase activity of the intestinal mucosa was tested as a proliferative marker in the adenoma-carcinoma sequence. The enzyme activity was determined by an end-point colorimetric method with L-arginine as substrate. Arginase activity was evaluated in 430 biopsy samples of large bowel mucosa, polyps and cancer tissue. The activities (U/g protein, mean +/- SE; n) were: normal mucosa 83.2 +/- 7.3;...
متن کاملCytokeratin 7-positive/cytokeratin 20-negative cecal adenocarcinoma metastatic to the uterine cervix: a case report
BACKGROUND The vast majority of uterine cervical malignancies are primary carcinomas, and secondary neoplasms that metastasize to the uterine cervix from a distant organ are uncommon. Although relatively rare, metastases to the uterine cervix from a primary colon cancer have been reported. We report a rare case of metastatic carcinoma originating from a cecal adenocarcinoma with an unusual cyto...
