BACKGROUND AND AIMS Several diagnostic methods are being employed to detect benign and malignant lesions, one of which is silver nitrate staining for organizer regions. The number of nucleolar organizing regions (NORs) can be used to show the degree of cell activity or metabolism in pathologic lesions. This study was designed to evaluate NORs as determi-nants of precancerous and squamous cell c...
متن کاملPrognostic significance of argyrophilic nucleolar organizer regions in esophageal carcinoma.
The argyrophilic nucleolar organizer region (AgNOR) of 100 cancer cells from biopsy specimens of esophageal squamous cell carcinomas in 98 surgically treated cases was examined, using a silver colloid staining technique on biopsy specimens. The number of AgNOR per nucleus (AgNOR number) was higher in the more advanced groups with regard to the length of the tumor (P less than 0.01), the depth o...
متن کاملNucleolar organizer regions of lymphomas in Korea.
Nucleolar organizer regions (NORs) are loops of DNA which occur in the nucleoli of cells and which possess ribosomal RNA (rRNA) genes. The numbers and/or configurations of NORs have been thought to be related to cellular activities. To assess the applicability of NORs associated protein (Ag-NORs) in the field of diagnostic histopathology, a silver staining was done in paraffin sections of malig...
متن کاملPredictive Value of Argyrophilic Nucleolar Organizer Regions at Invasive Tumor Front in Oral Squamous Cell Carcinoma
Purpose: While grading the tumor, histopathological evaluation of invasive front of the tumor is important as the morphological features registered reflect the important biological events within the tumor cells. This study was undertaken to determine the prognostic value of malignancy grading and Argyrophilic Nucleolar Organizer Region (AgNOR) method in assessment of proliferative activity at t...
