Others are light sensitive and require storage in the dark. These special stains have a long history of invention with the great efforts of the pioneer scientists and advent of new stain in line with the developments in the dye industry. The H&E stain uses two dyes: hematoxylin and eosin.

B This section shows an opportunistic fungal infection in lung (Aspergillus) stained with the Grocott-Gomori method. Figure 11: Perls Prussian Blue Iron (liver). One property of methylene blue and toluidine blue dyes is metachromasia. For all methods, the level of staining is assessed by looking at the slide with the naked eye. The cell walls of these organisms are stained, so the organisms are outlined by the brown to black stain. LEICA and the Leica Logo are registered trademarks of Leica Microsystems IR GmbH.

CHAPTER 6 STAINING 0000012883 00000 n There are a wide variety of special stains to demonstrate pathologic processes. Alcian Blue is normally prepared at pH 2.5 and is used to identify acid mucopolysaccharides and acidic mucins. The pH of this stain can be adjusted to give more specificity. Bacteria appear on H and E as blue rods or cocci regardless of gram reaction. Section A shows red smooth muscle.

In the histopathology laboratory, the term routine staining refers to the hematoxylin and eosin stain (H&E) that is used routinely with all tissue specimens to reveal the underlying tissue structures and conditions. The process for frozen section preparation is as follows: When paraffin sections are to be prepared the specimen is first preserved with a fixative and then the tissue structure is supported by infiltrating the specimen with paraffin wax.

He is a former Senior Lecturer in histopathology in the Department of Laboratory Medicine, RMIT University in Melbourne, Australia. These ions then react with potassium ferrocyanide to produce an insoluble blue compound (the Prussian blue reaction). Use of special stains for tissues not only aids in distinguishing structural alterations of tissues but also alerts the physician to alterations in tissue function highly relevant to making a diagnosis, such as abnormal deposition or iron, abnormal deposition of protein [amyloidosis, paraproteinemia, etc., abnormal accumulation of glycogen or Note the lack of differential coloration of muscle in section B (intestine). Hematoxylin reacts like abasicdye with a purplish blue colour. Just following the method and not really knowing what should be seen in the finished section will lead to poor results. Before tissue can be stained and viewed, it must be prepared so that a very thin section, only one cell thick, can be cut and placed onto amicroscope slide. 8632 Special Stains Used in Histopathological Techniques: A Scanning is the first step in Digital Pathology; put your best foot forward.

Gram positive organisms usually stain well, but gram negatives do not (because the lipid of the bacterial walls is removed in tissue processing). 1. TITLE: Special Stains Overview. 2. DEFINITION : The %PDF-1.5 % Before tissue can be stained and viewed, it must be prepared so that a very thin section, only one cell thick, can be cut and placed onto amicroscope slide. Staining of The process is more time-consuming than creating frozen sections, but provides better quality staining in most cases and the resultant samples (referred to as blocks) can be stored almost indefinitely. Anatomic Pathology Special Stains - Cleveland Clinic This autonomic ganglion from the myenteric plexus, located between the smooth muscle layers of the muscularis externa of the small intestine, contains ganglionic neurons that show well-defined basophilic Nissl substance (aggregations of endoplasmic reticulum and ribosomal RNA) in their cytoplasm.
