Histopathology of biodegradable polymers: terials, special emphasis should be given for providing a detailed summary of pathology results in addition. It can be done either by using dilute stain or cutting down the staining time. Figure 16: Gomori Trichrome (green) (submucosa). The van Gieson method for elastic fibers provides good contrast. PAS is useful for outlining tissue structuresbasement membranes, capsules, blood vessels, etc. They help in differential coloration of cells and tissues in a specimen, help in visualization and thereby assist pathologists in diagnosis. The variety of stains also means that special staining is not as automated as H&E staining. WebA counter stain is the application to the original stain, usually nuclear, or one or more dyes that by contrast will bring out heavy counterstain is to be avoided least it mask the nuclear stain. EDTA is a chelating agent that aids in the removal of calcium and mineral from cartilage or bone. It requires a formalin fixation. It is then oxidized and combined with a mordant (typically aluminium) to allow it to bind to the cell structures. These liver sections were stained by the same method. In this procedure the nuclear protein stains purple and the cytoplasm and any other substances stains as red The only difference between them was the technique by which they were rinsed between impregnation and reduction. There are a wide variety of special stains to demonstrate pathologic processes. Special Stains There are a variety of staining procedures used to identify specific external or internal structures that are not found in all bacterial species, such as a capsule stain and a flagella stain. WebSpecial stains are also performed on material received from cytology.

This information is often sufficient to allow a disease diagnosis based on the organization (or disorganization) of the cells and also shows any abnormalities or particular indicators in the actual cells (such as nuclear changes typically seen in cancer). Abnormal amounts of iron can indicate hemochromatosis and hemosiderosis. Our Open Innovation (OI) partnerships enable easy integration across technologies, supporting fluorescent and chromogenic protocols, and helping to answer your most pressing research questions. Fresh smears or cryostat sections of tissue are necessary because fixatives containing alcohols, or routine tissue processing with clearing, will remove lipids. Figure 14: Alcian Blue and PAS (intestine). Special stains are dyes or substances used for special purpose in a histopathology laboratory. This section from the mucosa of small intestine shows well-defined heterochromatin and nucleoli in epithelial cells and plasma cells within the lamina propria, Figure 3. It is very difficult to determine the cause of such a problem if the method has not been followed exactly (Gordon & Sweets method, kidney). Romanowsky stains may also be used for wet fixed slides, but are primarily applied to air-dried smears. 0000002051 00000 n LEICA and the Leica Logo are registered trademarks of Leica Microsystems IR GmbH.
