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...

conclusions the agnor technique can be used to diagnose salivary gland tumors. results the chi-square test showed significant differences between tumor types and the numbers of agnors (p = 0.000) and between tumor types and areas of agnors (p = 0.000). objectives the purpose of this study was to determine the numbers and mean areas of the agnor dots in the 3 most common salivary gland tumors. m...

Nucleolar organising regions (NOR) are part of the nucleolus, containing argyrophilic proteins (nucleoclin/C23, nucleophosmin/B23). They are identified by silver staining at low pH. The method also reveals osteocyte canaliculi and cement lines and granules in the cytoplasm of kidney cells in locations that mimic osteopontin distribution. Human bone and kidney sections, benign and lymphomatous p...

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...

Thirty cases of benign prostatic hyperplasia and 30 cases of prostatic adenocarcinoma were selected and stained by AgNOR (argyrophilic staining of the nucleolar organizer region) method. Specimens were obtained by either prostatectomy (open!TIJR) or needle biopsy of the prostate. In this study, the sections of prostatic adenocarcinoma were reviewed. 6 cases were diagnosed as well-differen...

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...

AIM To evaluate the usefulness of counting nucleolar organiser region associated proteins (AgNORs) in the management of anal squamous neoplasia. METHOD Using a silver staining technique for NOR associated proteins, 32 routinely processed paraffin wax embedded sections of anal epithelium were assessed. These consisted of normal anal epithelium (n = 9), anal intraepithelial neoplasia (AIN) grad...
