Silver staining of senile plaques and neurofibrillary tangles in paraffin sections. A simple and effective method
Reusche E.. Pathology, research and practice, 1991-12-01
Topic: Brain proteins, microglia and lab models
A one-step silver staining method using a protective colloidal developer of gelatin and formic acid was originally established for demonstration of argyrophilic nucleolus organizer regions by controlled reduction of silver. We describe here a new application of this silver technique that can easily be performed to demonstrate senile plaques (SP) and neurofibrillary tangles (NFT) on paraffin sections. Preliminary results in ten cases of senile dementia of Alzheimer type and five cases of amyloid congophilic angiopathy showed a reliable demonstration of amyloid and neuritic type SP as well as NFT in all 15 cases. In addition, deposits of perivascular amyloid and areas of fibrillar amyloid, the diffuse type of senile plaques, were revealed. The success seems to depend particularly on the low concentration of formic acid in the developer, which might be the responsible agent for the careful revealing of buried argyrophilic structures in SP and NFT. The staining features were quite similar to those with anti-beta and anti-tau immunostaining. This result suggests a high specificity of this method for extracellular and intraneuronal cerebral amyloid. The detailed staining of delicate morphological structures points to a high sensitivity for cerebral amyloids, senile plaques and neurofibrillary tangles, respectively, by this simple and inexpensive method.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomized / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
