fuchsin

(fyo͞ok`sĭn) or

magenta

(məjĕn`tə), bright red dyestuff consisting of the mixed hydrochlorides or acetates of rosaniline and pararosaniline. It is composed of small crystals possessing a brilliant green sheen; when dissolved they produce a red solution, which dyes animal fibers directly and vegetable fibers after mordanting. The solution is used in the textile and leather industries and as a stain in biology.

[′fyük·sən]
(organic chemistry)
C20H19N3 Brownish-red crystals, used as a dye or in the commercial preparation of other dyes, and as an antifungal drug. Also known as magenta; rosaniline.

The present study was undertaken with the objective to stain sputum samples in their containers by 'phenol (10%) ammonium sulphate (4%) basic fuchsin (2%) solution' and to decolourize and counterstain their smears for detection of AFB- (henceforth called pot method) and to compare the smear results of pot method with the standard Ziehl-Neelsen (ZN) method.
Paraffin sections were stained for calcium by the Von Kossa method, and resin-embedded semi-thin sections were stained with toluidine blue or with the malachite green and basic fuchsin method; all were observed by light microscopy.
Plaque scores were measured using the plaque-disclosing solution (basic fuchsin mouthwash) and the Turesky modification of Quigley and Hein's technique (Carranza and Newman, 1996) on a scale of 0 to 5: 0 = no plaque; 1 = separate flecks of plaque at the cervical margin of the tooth; 2 = a thin, continuous band of plaque (up to 1 mm) at the cervical margin; 3 = a band of plaque wider than 1 mm but covering less than one-third of the crown; 4 = plaque covering at least one-third but less than two-thirds of the crown; and 5= plaque covering two-thirds or more of the crown.
domesricus is suggested by earlier work showing that ovariectomy results in a decrease in the amount of paraldehyde fuchsin (PAF) positive material in the PIC and decreased levels of several PAF positive polypeptides in the brain and corpora cardiaca (Bradley and Simpson, 1981).
The stains were mostly Gram stains, Wright's stain, and a cold carbol fuchsin stain for AFB.
Charcot-Leyden crystals consist of a 13 000-molecular weight acidic protein whose amino acid composition distinguished it from the 9300-molecular weight major basic protein, the principal constituent of eosinophil large granules; this protein is identical to lysophospholipase (3) and is stained by basic fuchsin in the Ziehl-Neelsen method.
