Histopatologia da leishmaniose tegumentar por Leishmania braziliensis brazilien...
Magalhães, Albino Verçosa de; Moraes, Mario Augusto Pinto de; Raick, Alberto N.; Llanos Cuentas, Alejandro; Costa, Jackson Mauricio LopesOs A.A. analisaram a resposta humoral nas lesões de 90 pacientes de Leishmaniose Tegumentar causada por Leishmania braziliensis brasiliensis , utilizando o método da imunoperoxidase para identificar nos tecidos a presença de IgA, IgG, IgM, fração C3 do complemento e fibrina. Constataram a presença de IgA, IgC e IgM nos plasmócitos tissulares, com predomínio de IgG. Admitiram aue a passagem dessas imunoglobulina...

Magalhães, Albino Verçosa de; Moraes, Mario Augusto Pinto de; Raick, Alberto N.; Llanos Cuentas, Alejandro; Costa, Jackson Mauricio LopesOs A A. analisaram as alterações histológicas encontradas em 162 casos de Leishmaniose Tegumentar da localidade de Três Braços, Estado da Bahia, dos quais 131 (80,9%) eram de portadores de lesões cutâneas e 31 (19,1%) de portadores de lesões mucosas. Analisaram, também, o comportamento clínico dos cinco padrões histopatológicos, já antes descritos, em relação à terapêutica. O melhor prognóstico esteve sempre li...

Magalhães, Albino Verçosa de; Moraes, Mario Augusto Pinto de; Raick, Alberto N.; Llanos Cuentas, Alejandro; Costa, Jackson Mauricio LopesOs autores analisam material de biópsias de 378 casos de Leishmaniose Tegumentar, causada por Leishmania braziliensis braziliensis, da localidade endêmica de Três Braços (Estado da Bahia). O parásitos, embora escassos, foram encontrados em 63,7% dos casos da forma cutânea e em 37,5% dos casos da forma mucosa. As alterações dérmicas ou do córion da mucosa permitiram identificar cinco padrões histopatológicos: 1)...

A infiltração histiolinfoplasmocitária, na maioria dos casos, parece desempenhar o papel de resposta celul...
Pentavalent antimonial nephrotoxicity in the rat
Veiga, Joel Paulo R.; Khanam, Rashida; Rosa, Tânia T.; Junqueira Jr., Luiz F.; Brant, Plínio C.; Raick, Alberto N.; Friedman, HoracioAspects of the renal function were assessed in rats treated with the pentavalent antimonials Glucantime (Meglumine Antimoniate, Rhodia) or Pentostam (Sodium Stibogluconate, Wellcome). In dose of 30 mg of Sb v (Glucantime or Pentostam) by 100 mg of weight by day for 30 days, renal functional changes were observed consisting of disturbances in urine concentrating capacity. Such disturbances were expressed by sign...
Indirect immunofluorescent reaction in endemicus pemphigus foliaceus
Friedman, Horácio; Campbell, Iphis T.; Alvarez, Rosicler Rocha; Diaz, Luis A.; Castro, Raymundo Martins De; Roitman, Isaac; Parreiras, Rosa M.The aim of the present research was to standardize the indirect immunofluorescence reaction for Endemic Pemphigus Foliaceus (Fogo Selvagem). We found that fresh human skin was the ideal substrate and could proceed from foreskin, head, neck, or anterior abdominal wall. PBS pre-washing of the skin preceding the incubation with the serum should be avoided since the antigenicity might be diminished. TAS-calcium pre...
Fatal case of human pulmonary adiaspiromycosis
Moraes, Mário A. P.; Almeida, Marcos Célio de; Raick, Alberto N.A fatal case of human pulmonary adiaspiromycosis is reported. The patient, a male farm laborer from Pernambuco, in the Northeastern part of Brazil, had moved to Planaltina, DF., one year prior the onset of his illness. The main clinical manifestations consisted in fever, myalgia, cough and dyspnea. After being sick for five weeks, the patient developed severe respiratory failure and died. Grossly, disseminated ...
Histopathology of mucocutaneous leishmaniasis caused by Leishmania braziliensis...
Magalhães, Albino Verbosa de; Moraes, Mario A. P.; Raick, Alberto N.; Llanos-Cuentas, Alejandro; Costa, Jackson M. L.; Cuba, Cesar C.The Authors describe the histopathological findings observed in biopsies from 378 cases of Mucocutaneous Leishmaniasis, caused by Leishmania braziliensis braziliensis. All the patients lived in the locality of Três Braços, State of Bahia, an endemic area of Leishmaniasis in Brazil. Parasites were found in 63.7% of patients with cutaneous form and in 35.7% of cases with mucous lesions, although always in reduced...

Magalhães, Albino Verçosa de; Moraes, Mário A. P.; Raick, Alberto N.; Llanos-Cuentas, Alejandro; Costa, Jackson M. L.; Cuba, César C.The Authors analysed the humoral response in biopsy material from 90 patients with Mucocutaneous Leishmaniasis caused by Leishmania braziliensis braziliensis, utilising the immunoperoxidase method to identify IgA, IgG, IgM, C3 complement fraction and fibrin in the tissue. The presence of IgG, IgA and IgM was found in tissue plasma cells with a predominance of IgG and this was correlated significantly with the n...

Magalhães, Albino Verçosa de; Moraes, Mário A. P.; Raick, Alberto N.; Llanos-Cuentas, Alejandro; Costa, Jackson M. L.; Cuba, César C.The Authors analyse the histopathological alterations observed in 378 cases of Mucocutaneous Leishmaniasis from Três Braços, Bahia, of whom 307 (81,4%) were only cutaneous, 54 (14,2%) only mucosae and in 17 (4,4%) both integuments were involved simultaneously. A cellular infiltration of lymphocytes and plasma cells was invariably present in all forms and during healing. In mucosal cases, this reaction may have ...
