Bachground & Aims: Oral lichenoid reactions (OLR) and oral lichen planus (OLP) are clinically and histopathologically similar but their therapeutic approach are different. Due to the presence of dysplasia in oral lichen planus which effects prognosis, the aim of study was the evaluation of proliferation activity of OLPs and OLRs and their subtypes. AgNOR technique that is inexpensive and easy...

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...

Chromosome numbers, morphology, and nucleolus organizer region (NOR) locations are useful cytological characters for taxonomic and evolutionary studies. In this study, we provide the first cytogenetic analysis of Phyllomedusa bahiana and Phasmahyla spectabilis, and report new cytogenetic data on variation in NOR numbers and positions in Phyllomedusa rohdei and Phyllomedusa nordestina using conv...

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...

PURPOSE The purpose of the present study was to investigate the possible role of Ki-67 and argyrophilic nucleolar organizing regions (AgNOR) between the recurrent and nonrecurrent keratocystic odontogenic tumors (KCOTs). Another aim was to compare the correlation between these two markers. MATERIALS AND METHODS 22 KCOTs were evaluated retrospectively. The actual proliferative activity of the ...

Mucoepidermoid carcinoma (MEC) is a malignant glandular epithelial neoplasm having an unpredictable behavior and a tendency to recur. Numerous parameters have been assessed to predict the outcome of this lesion, but have been deemed inadequate, with the exception of tumor stage and grade. In the present study, we attempted to correlate the proliferative activity of MEC with its histopathologica...

Prof. Dr. K. Metze, Department of Pathology, Faculty of Medicine, POB 6111, State University of Campinas, BR 13081 Campinas-SP (Brazil) Nucleolar organizer regions (AgNORs) have been widely studied in a variety of neoplasias, but only a few investigations deal with AgNORs in blood diseases. We therefore read with interest the study by Nakamura et al. [1] on AgNORs in acute leuke-mias, and would...

We present the karyotype characteristics of five cytotypes of mole rats (Nannospalax) with 56 chromosomes revealed by the C-banding and AgNOR staining analyses. We attempt to investigate if the specific distinction between the populations from Thrace (N. leucodon) and Anatolia (N. xanthodon) is reflected also in their karyotypic differentiation. The specimens from each of the five populations s...

argyrophilic nucleolar organizer regions (agnors) were determined in 94 pleural, pericardial and peritoneal effusions. the results were correlated with cytologic diagnosis to determine the diagnostic potential of this technique. cytologically the number of normal, reactive and malignant effusions were 32, 28 and 34 respectively. the mean agnor counts for normal, reactive and malignant specimens...

.. Background: The aim of this study was to evaluate clinico-pathological parameters and the status of argyrophilic nucleolar organizer regions stain in various histological grades of oral squamous cell carcinoma. Materials and Methods: A cross sectional study was conducted on fifty cases of oral squamous cell carcinoma. The specimen were collected from the department of Oral & Maxillofacial Su...
