aldehyde fuchsin

al·de·hyde fuch·sin

a stain using basic fuchsin paraldehyde and hydrochloric acid; it produces violet staining of elastic fibers, mast cell granules, gastric chief cells, β cells of the pancreatic islets, and certain hypophyseal β granules; other pituitary granules and cells stain in other colors.

Modified aldehyde fuchsin staining showed that pancreas of the diabetic rats had irregular islet with decreased secretory granules in beta cells, but changes of pancreatic islet in the animals were minimized by administration of extract.
Tissue sections of 5um thickness were obtained to stain with haematoxylin and eosin stain (HandE) and aldehyde fuchsin stain for beta cells and immunohistochemical (IHC) stain using Bandeiraeasimplicifolia (BS)-1 lectinto stain intra-islet capillaries.
Sections of anterior, mid and posterior intestinal segments were also treated with different staining methods of alcian blue (AB) at pH 2.5, aldehyde fuchsin (AF), periodic acid-Schiff (PAS), KOH/PAS and PAS/AB (pH 2.5) and investigated.
To identify different contents of the goblet cells, the staining methods of alcian blue (AB) at pH 2.5 for acidic glycoconjugates with carboxylated and sulfate esters; aldehyde fuchsin (AF) for glycoconjugates with sulfate; periodic acid (0.5%)-Schiff reagent (PAS) for neutral glycoconjugates; potassium hydroxide/PAS (KOH/PAS) for glycoconjugates with sialic acid residues; and PAS/AB (pH 2.5) to distinguish between neutral and acidic glycoconjugates (Cinar and Senol, 2006) were performed (Presnell et al., 1997).
In addition, stained pancreas was washed with Gomori's aldehyde fuchsin for determination of [beta]-cells in Langerhans islets (Gomori, 1950) as described below.
Histological pancreas islets were checked separately in hematoxylin and eosin with aldehyde fuchsin section.
