Abstract: | Possibilities of application of some histochemical methods to studying cell nuclei of brain are reviewed considering the following techniques: hybridization histochemistry on the light and electron microscope levels, immunohistochemistry and immunoelectron microscopy, absorbtion and fluorescence histochemistry of nucleic acids, histones, non-histone proteins of chromatin, and of cell nucleus lipids, electron histochemistry. Besides, some physicochemical and molecular-biological methods are considered. Data on human brain research in the norm and upon various brain disorders are particularly provided. |
