The distinction of the modification of Bielschowsky's method lies in additional colouring of silver-golden sections with strong solutions of stable cresyl-violet and acetic acid, as well as in recommendations to use precise-profile cortical sections. The given modification helps to obtain preparations with definite orientation and guaranteed identification of different nerve tissue elements. The preparations obtained can be employed for quantitative analysis and for a detailed study of thin specific structures and cytologic properties of pathologically changed nerve and glial cells.
