A quantitative method to determine glycocalyx production by strains of viridans group streptococci from patients with endocarditis is presented. There is good correlation between this new tryptophan quantitative assay and qualitative assays employing polysaccharide stains (ruthenium red, periodic acid-Schiff, and Cellufluor) or the Molisch test. The quantification of the glycocalyx production i...

A 46-year-old woman presented with lower abdominal pain, diarrhea and irregular vaginal bleeding persisting for the past 2 months. She had a history of cervical cancer treated with concurrent chemoradiotherapy 6 years previously, which was successful. Magnetic resonance imaging with T2-weighted and diffusion images showed a high intensity area in the cervix, suggestive of recurrent cervical can...

The complex carbohydrates in the undescended and contralateral scrotal testes of patients with cryptorchidism, were examined by light microscopic histochemical methods, in comparison with those of normal testes. In the undescended testes, histochemical reactions for acidic and neutral complex carbohydrates were apparently weaker than in the normal testes, especially pronounced in the seminifero...

We have modified the periodic acid-Schiff staining technique for glycoproteins for use with thin agarose-film electrophoresis membranes. With this procedure, carbohydrate-rich proteins can be detected with negligible background staining and insignificant staining of nonglycoproteins such as albumin and nonglycosylated Bence Jones proteins (free light chains). On the other hand, carbohydrate-ric...

Eccrine porocarcinoma (EP) is a rare malignant tumor arising from the intraepidermal eccrine duct. The tumor cells frequently contain glycogen, but prominent clear cell changes in EP are rarely reported. A 78-year-old woman presented with a slightly pruritic, erythematous, verrucous plaque on her left thigh. Histopathological examination revealed intraepidermal tumor cell nests composed of smal...

THE existence of a basal structure separating the different epithelia (glandular, cutaneous) from their stroma, is well known. The histopathology of this basal membrane has been especially well studied at the dermo-epidermic junction, where it is seen as a dense layer, intensely coloured by periodic acid-Schiff (Dupre, 1953; Lever, 1954). Percival and Hannay (1949) noted that it forms an intrac...

A perivascular epithelioid cell (PEC) tumor is a rare mesenchymal tumor characterized by abundant cytoplasmic Periodic acid-Schiff positive glycogen (also called sugar tumor or clear cell tumor of the lung for this characteristic) and is mostly benign. We report a case of a 63-year-old man who presented with an enlarging mass on chest radiograph. After a thorough workup, diagnosis of malignant ...
