AIM To demonstrate the role of cytopathology in examining tumours found at post mortem examination. METHODS Tumour deposits were found in 25 hospital necropsies. Cytological diagnosis made at the time of necropsy was compared with subsequent paraffin wax embedded histological sections. RESULTS In 19 out of 20 cases with no previous histological diagnosis, cytology at the time of necropsy pr...

An experimental model was established using the terminal ileum of the rat for characterizing and studying the effects of crude cell-free extract from Clostridium perfringens upon physiological and histological parameters involved in the transport process. Further work was done with the model system using purified enterotoxin (protein) from the cell extract. Using an in vivo perfusion technique ...

A total of 113 fine needle aspirates of the breast masses were evaluated in which the subsequent biopsy or mastectomy specimen were also available for histological examination. The age ranged from 16 to 80 years with a mean of 42 years. In benign conditions the mean age was 34.7 years while in malignant cases it was 48 years. The cytological diagnoses were compared with the histological results...

The paper presents our approach to reconstruction after periocular basalioma (pBCC) excision, especially of large lower lid (LL) and medial canthal (MC) pBCC. Retrospective analysis of data of 123 patients with pBCC, confirmed on histologic examination (HE), operated in period from 1998 to 2006, was performed. Oncologic safety margins of 3 mm were marked after local anesthesia was administered....

Electrical impedance is one of the most frequently used parameters for characterizing material properties. The resistive and capacitive characteristics of tissue may be revealed by electrical impedance spectroscopy (EIS) as electrical biopsy. This technique could be used to monitor the sequelae after irradiation. In this study, rat intestinal tissues after irradiation were assessed by EIS syste...

The aim of this histological study was to analyze the gingival reaction to fixed orthodontic appliances. Gingival specimens were obtained with minimal trauma from 11 patients treated with fixed appliances in different intervals during the orthodontic treatment, including post-treatment periods. Serial sections were stained with Hematoxylin-Eosin. T- and B-cells were identified by specific antib...

Periodontal research involves the use of animal models to better understand the biological processes of periodontal diseases and the potential of new or existing therapies. Currently, ligature-induced periodontitis in rats is the main model used in periodontal research, in this model, alveolar bone loss (ABL) is the main parameter evaluated by radiographic, morphometric, and histological techni...

The aim of our work was to study the expression of apoptosis in the cephalic region in human embryonic and fetal material. Twelve human embryos and fetuses were processed by routine histological technique and then studied using the Boehringer-Mannheim Company kit for TUNNEL technique. Rich appearance of apoptotic cells was typical for mesenchyme and for tissues of the mesenchymal origin. Disper...

The purpose of this study is to explore the role visualization histological tasks in improving quality knowledge, abilities, and skills medical students by summarizing work experience Department Histology, Cytology, Embryology.
 In field higher education, discipline "Histology, Embryology" crucial as it forms foundation students' understanding microscopic functional morphology, structure, ...
