PURPOSE: This stain is useful in demonstrating atrophy of elastic tissue in cases of emphysema, and the thinning and loss of elastic fibers in arteriosclerosis, and other vascular diseases.
Why is staining used in histology?
Staining is used to highlight important features of the tissue as well as to enhance the tissue contrast. Hematoxylin is a basic dye that is commonly used in this process and stains the nuclei giving it a bluish color while eosin (another stain dye used in histology) stains the cell’s nucleus giving it a pinkish stain.
When was silver staining used in histology?
This historic technique allowed Santiago Ramón y Cajal (1852–1934) to interpret the structure of the central nervous system. There are also a range of other silver staining techniques (see silver staining reticular fibres). Developed in 1950 by an American histologist George Gömöri (1904–1957).
What is Golgi stain in psychology?

There are also a range of other silver staining techniques (see silver staining reticular fibres).
