OBJECTIVE to evaluate the relationship between AgNORs count as well as tumor grade and the effect of chemotherapy in serous ovarian cancer. MATERIAL AND METHODS 39 women who underwent surgical procedure and then chemotherapy due to serous ovarian cancer were included into the study. In cancer cells the mean number of AgNORs per nucleus (mAgNOR) and the mean percentage of nuclei with five or m...

Aim-To evaluate the expression of ribosomal cistrons in human thyroid epithelial cells (TECs) of patients with Grave's disease, Hashimoto's thyroiditis and benign and malignant tumours of the thyroid gland.Methods-TEC nucleoli were investigated in fine needle biopsy specimens from 10 controls, 39 patients with Grave's disease, 15 with Hashimoto's thyroiditis, 56 with benign, and 15 with maligna...

AIM To evaluate the interphase ribosomal RNA cistron activity of cardiomyocytes in case with ischaemic heart disease complicated by heart failure. METHODS Nucleoli were investigated in postmortem myocardium samples from 31 cases with ischaemic heart disease (mean (SEM), 57.4 (6.5) years) with or without severe heart failure (18 and 13, respectively) and from eight healthy people who died in a...

Early detection of oral squamous cell carcinoma (OSCC) and potentially malignant disorders (OPMD) is important for dental professionals to improve patient survival rates. More than half patients with cancer had advanced disease at the time diagnosis, indicating a lack early risk assessment biomarkers. The development new protein biomarkers will help in diagnosis treatment.The argyrophilic nucle...

A new staining method for dual demonstration of Estrogen receptors (ER) and argyrophilc Nucleolus-Organizer Regions (AgNORs) was developed. To rule out possible reciprocal effects, serial slides of 10 invasive ductale breast cancers were stained with either the single staining method or the simultaneous ER/AgNOR-staining method and investigated comparatively. By measuring the slides with the im...

AIMS To investigate the relation between the numbers of interphase silver stained nucleolar organiser regions (AgNORs) and immunolabelling with the monoclonal antibody PC10, which demonstrates proliferating nuclei by reacting with proliferating cell nuclear antigen (PCNA). METHODS The established sequential technique for the demonstration of interphase AgNORs and of antigens in paraffin wax s...
