    A study of dementia with argyrophilic grains (1995)

    Notes: Abstract Two mildly demented patients with emotional disorder presented massive cortical argyrophilic grains (ArG) in the limbic area and coiled bodies mainly in the white matter. Immunohistochemically, the ArG consisted of partially ubiquitinated full-length phosphorylated tau. A modified Gallyas-Braak method, used after potassium permanganate and oxalic acid pretreatment, revealed many filiform, knobby or pleomorphic spine-like appendages on the ArG. Double immunohistochemical staining using anti-tau with either anti-microtubule-associated protein 2 or anti-neurofilament 200K revealed that ArG were intimately associated with dendrites rather than with axons. Electron microscopic studies with tau immunohistochemistry and the Gallyas-Braak method revealed that the ArG were composed of bundles of smooth tubules of 25-nm diameter. The coiled body-bearing cells had the morphological characteristic of oligodendroglia. These results indicate that the presence of ArG is a cytoskeletal abnormality affecting predominantly the dendrospinal portions of neurons. A survey of diseases with cytoskeletal disorders revealed that a small number of similar argyrophilic granular structures are sometimes observed in progressive supranuclear palsy, Pick's disease with Pick bodies and corticobasal degeneration. Dementia with ArG is thought to be a unique cytoskeletal abnormality associated predominantly with the dendrospinal portions of neurons and oligodendroglia.

    Distinctive, rapid, and easy labeling of diffuse plaques in the Alzheimer brains by a new methenamine silver stain (1990)
    Springer

    Notes: Summary We have developed a new methenamine silver (MS) stain for detecting diffuse plaques distinctively on paraffin-embedded tissue sections of Alzheimer-type dementia, Down'n syndrome, and mentally normal aged brains. This rapid and easy method selectively labels amyloid-related component of senile plaques, but not of kuru plaques found in Gerstmann-Sträussler syndrome. Our MS stain shows almost the same staining pattern as that of the β protein immunostaining with formic acid pretreatment. Therefore, new MS stain is appropriate to routine or screening studies for senile plaques including diffuse plaques.

    Ultrastructural and immunohistochemical study of degenerate neurite-bearing ghost tangles (1992)
    Springer
    Journal of neurology 239 (1992), S. 191-194 
    Details
    ISSN: 1432-1459
    Keywords: Ghost tangles ; Degenerate neurites ; Astrocytes ; Senile plaques ; Ultrastructure
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Some ghost tangles in the brains of Alzheimer patients were accompanied by many small argyrophilic structures which were electron microscopically confirmed to be degenerate neurites. In these ghost tangles, roughly dispersed 15 nm straight and occasional twisted tubules were penetrated by proliferated astrocytic processes. Immunohistochemically, these ghost tangles lost immunoreactivities to anti-NFT, -tau and -ubiquitin antibodies, but were thioflavine-S fluorescent, though antigenicity to β-protein was not proved. This similarity in composition of degenerate neurite-bearing ghost tangles to senile plaques might be induced by the amyloid nature of tubules, which probably provokes the reaction of neuropils.
