Nucleolar 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 کاملNucleolar Organizer Regions of Oral Epithelial Cells in Crack Cocaine Users
Background: The health risks of crack cocaine smoking on the oral mucosa has not been widely researched and documented. Objective: The purpose of this study was to analyze the proliferative activity of oral epithelial cells exposed to crack cocaine smoke using silver nucleolar organizer region (AgNOR) staining. Methods: Oral smears were collected from clinically normal-appearing buccal mucosa b...
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...

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 determinants of precancerous and squamous cell c...
متن کاملSignificance of Nucleolar Organizer Regions in Prostate Adenocarcinomas
The aim of this study was to define the relation between silver stained nucleolar organizer regions (AgNORs) count and histological grade, and clinical stage in needle biopsy specimens of 65 prostatic adenocarcinomas. Histological grade was determined according to the modified Gleason system. AgNORs were evaluated by the counting method on routine histological sections stained with silver. Ther...
