(redirected from Silver stains)

sil·ver stain

any of a variety of stains (for example, Bielschowsky, Gomori silver, impregnation stains) that employ alkaline silver nitrate solutions to stain connective tissue fibers (reticulin, collagen), calcium salt deposits, spirochetes, neurologic tissue, and nucleolar organizer regions.

Periodic acid--Schiff, gram, and Grocott silver stains are all positive.
Abundant extracellular oval budding yeast forms were seen on hematoxylin and eosin and Grocott's methenamine silver stains (Figure 1(c)).
Molecular factors associated with prognosis are hormone receptor status, HER 2 status, Ki-67 and Argyrophilic Nucleolar Organizer Regions (AgNORs) silver stains.5,6
Slides were stained with Haematoxylin and Eosin, Papanicolaou, Periodic Acid Schiff's and Gomori's methenamine silver stains. Increased frequency of mucositis, oral ulcers, oral hairy leukoplakia (OHL), chronic periodontitis and oral wart was seen in ART group as compared to Non-ART group while oral mucosal pigmentation was significantly higher in ART group (p=0.00).
It actually demonstrates fungal morphology better than the silver stains. The PAS can stain degenerated fungi that may not be visible on H&E stain.
In paragraph six of the discussion, the authors state that in the Periodic Acid-Schiff (PAS) stains and in the Gomori-Grocott and Gridley's methenamine silver stains, the characteristic structures of H.
Historically, silver stains, including modified Steiner or Warthin-Starry stains, have been used to highlight spirochetes in cases of suspected syphilis (Figure 3, C); however, these stains have suboptimal sensitivity and specificity.
Histopathological examination usually shows an abscess or a granulomatous lesion with presence of pigmented yeasts and pseudohyphae or septate hyphae which will show positivity for periodic acid Schiff and Gomori's methanamine silver stains. They are also typically positive for Masson-Fontana stain confirming the presence of melanin in their cell walls, which has shown to be important in providing a protective advantage in evading host defenses in these fungi.
The present work aims for a comparative study of partially purified SPGs of goat, buffalo and pig with human erythrocyte membranes by solvent (chloroform-methanol) extraction, separation by SDS-PAGE and followed by staining with PAS, CBB and Silver stains.
(8,9) Senile or neuritic plaques, which are composed of tortuous neuritic processes surrounding a central amyloid core, are best visualized using silver stains or immunohistochemistry for amyloid beta (A[beta]) protein.
Fungal elements highlighted with periodic acid-Schiff and Gomori methenamine silver stains showed double-contoured cell walls surrounding a cytoplasmic mass and proliferation in the form of broad-based buds.
