28. Estudo comparativo entre vitiligo, nevo halo e lúpus eritematoso vitiligóide por meio de métodos imunológicos, histológicos e imuno-histoquímicos
FUNDAMENTOS: O estudo compara o vitiligo, o nevo halo (NH) e lúpus eritematoso vitiligóide (LEV) do ponto de vista imunológico, histológico e histoquímico. OBJETIVOS: Avaliar diferenças imuno-histoquímicas entre essas doenças e investigar se a despigmentação do LEV deve-se à destruição pós-inflamatória ou à agressão imunológica aos melanóc

31. Argentaffin and argyrophil reactions and serotonin content of endocrine tumours.
Sixty carcinoid tumours were tested in a retrospective study with an immunoperoxidase technique using a monoclonal antibody against serotonin immunoreactive sites, with argyrophil staining using the Grimelius technique, and with argentaffin staining using the Masson-Fontana technique. A good correlation between all three techniques in the diagnosis of ileal

32. Use of benzidine for histological demonstration of haemoglobin in human bite marks.
Macroscopic evidence of bruising from human bite marks may be inconclusive and routine histochemical methods of showing extravasated erythrocytes can be unreliable. Leuco patent blue staining, for the presence of peroxidase, Amido black B, a tinctorial staining method for haemoglobin, Perls's reaction for ferric iron (haemosiderin), Masson-Fontana for melani

34. Osteolytic phaeohyphomycosis in a German shepherd dog caused by Phialemonium obovatum.
Phialemonium obovatum was found to be the cause of osteomyelitis in a German shepherd dog. Histologic examination of the biopsied material from the left tibia revealed septate, irregularly branched hyphae, swollen cells, and ovate-to-spherical cells divided by a transverse septum. The majority of the fungal elements were hyaline, but a few had lightly pigmen

35. Mycoleptodiscus indicus: a new etiologic agent of phaeohyphomycosis.
Mycoleptodiscus indicus, a dematiaceous hyphomycete, was identified as the causal agent of subcutaneous infection in the knee of a 72-year-old male gardener residing in coastal South Carolina. The patient had Wegener's granulomatosis and immunodeficiency. Synovial fluid and biopsy tissue sections from the prepatellar bursa stained with hematoxylin and eosin,
