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...

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-differentiated...

Aims-To study correlations between the pattern of silver stained nucleolar organiser regions (AgNORs) in chronic lymphocytic leukaemia (CLL) and parameters of tumour kinetics. To investigate whether quantitation of the AgNOR pattern can be used to discriminate between patients with stable and progressive disease.Methods-Peripheral blood smears from 48 patients with CLL, classified as having eit...

Background: It is well known that tobacco smoke causes cellular proliferation and chronic obstructive pulmonary disease (COPD), but changes in buccal mucosa cells in smokers and COPD patients remains unknown. Aims: The aim of this study is twofold: (i) to assess the effect of smoking on cellular proliferative activity of buccal mucosa in healthy smokers and in smoking COPD patients (ii) to dete...

Aydınlatma, modern tavuk yetiştiriciliğinde, üreme, büyüme, vücut sıcaklığı, yem tüketimi ve sindirim olayları da dahil olmak üzere birçok fizyolojik süreci etkileyen metabolik olaylarda belirleyici rol oynayan önemli unsurlardan biridir. Aydınlatmaya bağlı olarak oluşan değişiklikler, sinir sistemi endokrin sistemin görev aldığı olaylar sonucu meydana gelmektedir. Purkinje hücreleri, merkezi s...

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...

Neurotoxic lesions of the nigrostriatal pathway model the deficits found in Parkinson's disease. This study used stereology and a novel staining method to examine the effects of a partial unilateral striatal 6-hydroxydopamine (6-OHDA) lesion on substantia nigra pars compacta (SNpc) dopamine neuron number and morphology in rats. Adult male Long-Evans rats were subjected to unilateral lesion of t...

OBJECTIVE The aim of this retrospective study was to report on the diagnostic accuracy of AgNOR-analysis as an adjunctive diagnostic tool of conventional oral exfoliative cytology taken from suspicious lesions in our clinic. STUDY DESIGN Cytological diagnoses obtained from brush biopsies of macroscopically suspicious lesions of the oral mucosa from 75 patients (final diagnoses: 53 histologica...

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...
