It is not uncommon to receive hemorrhagic fluids for cytological examination. The red blood cells impair diagnostic efficacy of smears. The body fluid can be processed in many waysNSRT (Normal saline rehydration technique) is one such technique. The present study was done to evaluate quality of smears prepared by NSRT and Carnoy’s fixation. The smears were stained by Hematoxylin & Eosin and Lei...

In three experiments of the normal human epidermis under different biopsy and fixative buffer conditions, Langerhans cells (LCs) in all mitotic phases were found with the Thin-Section-Reembedding and Ultrathin-Sectioning (TRUS) technique; two in the prophase, five in the metaphase, two in the anaphase and two in the telophase. The serial light microscopic examination showed many characteristic ...

The blood supply of myomatous uteri collected upon autopsy was examined. The uterine vascular beds were perfused via afferent vessels with fixative followed by Mercox resin and corroded after polymerisation of the resin. The vascular casts thus obtained were examined using scanning electron microscopy. The vascular system of the uterine fibroids was also examined using immunohistochemical analy...

A new technique for fixation of Biomphalaria glabrata for histologic studies is described. It consists in performing several external holes in the shell, before placing the entire snail into the fixative. It is a very practical and quick procedure that showed excellent results when compared to the usual techniques.

OsO(4) has many advantages over Carnoy's fixative mixture for the Feulgen nuclear staining in the protozoan Tokophrya infusionum. While Carnoy's fluid used prior to the Feulgen reaction produces shrinkage of the macronucleus and coarse clumping of its chromatin bodies, OsO(4) preserves faithfully the size and shape of the macronucleus and its chromatin material. This finding seems to be of spec...

AIMS To investigate the problems involved in undertaking immunohistochemistry (IHC) and nuclear morphometry using Bouin's fixed prostate biopsies. METHODS Archival Bouin's fixed and formalin fixed, paraffin wax embedded prostatic biopsies were immunostained for three nuclear biomarkers (minichromosome maintenance protein 2 (MCM-2), p27, and Ki-67), one membrane localised biomarker (C-erb-B2),...

The axonal initial segment (AIS) is the subcellular compartment required for initiation of the action potential in neurons. Scaffolding and regulatory proteins at the AIS cluster with ion channels ensuring the integrity of electrical signaling. Interference with the configuration of this protein network can lead to profound effects on neuronal polarity, excitability, cell-to-cell connectivity a...
