Periodic acid Schiff's: A definitive stain in histopathological diagnosis of Cylindroma

New, special stain for histopathological diagnosis of cryptococcosis.

The Masson-Fontana silver stain for melanin was employed for the differentiation of pathogenic fungal species in human or mouse tissues. The fungi studied were Candida albicans, Candida tropicalis, Candida glabrata (Torulopsis glabrata), Cryptococcus neoformans, Cryptococcus bacillisporus, Coccidioides immitis, Blastomyces dermatitidis, Histoplasma capsulatum, Paracoccidioides brasiliensis, Spo...

A colorimetric assay for glycoproteins based on the periodic acid/Schiff stain [proceedings].

of trypsin without EDTA. A monolayer of radioactively labelled BHK cells was incubated at 37°C for2min in 0.25 % trypsin; one half of the cells in suspension were harvested, washed and assayed for adhesion, and the other half of the cells were incubated for a further 15min in 0.25% trypsin before harvesting, washing and assaying for adhesion. Cells incubated in trypsin for only 2min did not sho...

The periodic acid-Schiff stain for the demonstration of fungi in animal tissue.

The routine histopathologic stains used for the demonstration of fungi in animal tissue are inadequate. The fungi are differentiated poorly and sometimes not at all. This is a limitation in the diagnosis of the mycotic granulomas in which the organisms may be rare. A definitive fungus stain, therefore, is needed, particularly by the pathologist and mycologist. During an attempt to stain the cap...

An allochrome periodic acid-methenamine silver stain for demonstrating mycobacteria in tissue sections.

Nyka9) employed the Gomori-Grocott's chromic acid-methenamine silver method for demonstrating tubercle bacilli in tissue sections after sublimate fixative with added hydrogen peroxide or periodic acid. He described that this procedure could demonstrate mycobacteria that had lost their acidfastness by the usual carbol fuchsin stain. Harada5) also employed the periodic acid-methenamine silver sta...
