Objective-To investigate whether and to what extent the two major AgNOR proteins, nucleolin and protein B23, are maintained after one cell division in proliferating cells.Design-Using three asynchronously growing human cancer cell lines, TG, SJNKP, and CHP 212 cells, nucleolin and protein B23 were first identified on SDS-polyacrylamide separated nucleolar proteins, transferred to nitrocellulose...

AIM To evaluate the interphase ribosomal RNA cistron activity of cardiomyocytes in surgical patients with chronic ischaemic heart disease by means of the nucleolar organiser region silver staining (AgNOR) technique. METHODS Nucleoli were investigated in myocardial samples obtained from 46 patients with chronic ischaemic heart disease before, during, and soon after cardioplegia ischaemia. Cryo...

The misery of women due to cervical cancer, which is the commonest cancer in women in a developing country like ours is a scourge of humanity. Early detection and management of squamous intraepithelial lesions (SIL) is the best approach to achieve control over cancer cervix. Cytological screening by Pap smear has brought down the incidence of cervical cancer in developed countries 1. Unfortunat...

Objective: This study is planned to evaluate the histological lesions of prostatic specimens and it’s correlation with the clinical data.Materials and Methods: The present study is a prospective study, undertaken in the Department of Pathology, Mahatma Gandhi Medical College, Jaipur, Rajasthan, during the period of July 2010 to May 2012. This study was conducted on 100 prostatic specimens refer...

In this study, quantitative DNA estimation (DNA ploidy), AgNORs and koilocytotic changes were assessed in oral leukoplakia for risk categorization. Materials and methods: 50 cases of oral leukoplakias along with adequate controls were selected for the study. Quantitative DNA analysis was done by FACS scan. AgNORs were studied by silver staining method, koilocytotic changes and histopathology we...

We studied argyrophilic proteins associated with nucleolar organizer regions (AgNOR) in non-small-cell cancer. We determined the area index (AI) and coefficient of variation (CV) of AgNOR. AI is associated with the key clinicomorphological parameters within the TNM system: T and N values, greatest tumor dimension up to 3 cm and more, disease stage, histogenesis, and tumor differentiation. CV is...

Pathological diagnosis of prostate adenocarcinoma often requires complementary methods. On prostate biopsy tissue from 39 patients including benign nodular hyperplasia (BNH), atypical adenomatous hyperplasia (AAH), and adenocarcinomas, we have performed combined histochemical-immunohistochemical stainings for argyrophilic nucleolar organizer regions (AgNORs) and glandular basal cells. After asc...
