Ocorrência de Bacillus cereus em leite integral e capacidade enterotoxigênica d...

Pesquisaram-se a presença de Bacillus cereus e a produção de enterotoxinas produzidas por esses microrganismos em 120 amostras de diversos tipos de leite. Bacillus cereus foi isolado e identificado em 22 (73,3%), 15 (50,0%), 29 (96,7%) e quatro (13,3%) amostras de leite em pó, cru, pasteurizado e UAT (longa vida), respectivamente. Para a detecção de enterotoxinas pela técnica da alça ligada de coelho, foram pos...

High frequency of mutation G377S in Brazilian type 3 Gaucher disease patients

Gaucher disease (GD), the most prevalent lysosome storage disorder, presents an autosomal recessive mode of inheritance. It is a paradigm for therapeutic intervention in medical genetics due to the existence of effective enzyme replacement therapy. We report here the analysis of GD in 262 unrelated Brazilian patients, carried out in order to establish the frequency of the most common mutations and to provide pr...

Microrganismos heterotróficos mesófilos e bactérias do grupo do Bacillus cereus...

Cento e dez amostras de 11 diferentes marcas de leite ultra alta temperatura (UAT), comercializadas em São José do Rio Preto - SP, foram submetidas à contagem de microrganismos heterotróficos mesófilos viáveis e à pesquisa de bactérias do grupo do Bacillus cereus. A população de microrganismos mesófilos variou de <1,0<FONT FACE=Symbol>&acute;</FONT>10² UFC/ml a >1,0<FONT FACE=Symbol>&acute;</FONT>10(6) UFC/ml. ...

Thalidomide and pentoxifylline block the renal effects of supernatants of macro...

Because thalidomide and pentoxifylline inhibit the synthesis and release of tumor necrosis factor-alpha (TNF-alpha), we determined the effect of these drugs on the renal damage induced by supernatants of macrophages activated with Crotalus durissus cascavella venom in order to identify the role of TNF-alpha in the process. Rat peritoneal macrophages were collected with RPMI medium and stimulated in vitro with C...

Actions of Crotalus durissus terrificus venom and crotoxin on the isolated rat ...

Many studies have reported the occurrence of lethal acute renal failure after snakebites. The aim of the present investigation was to determine alterations in renal function produced by Crotalus durissus terrificus venom and crotoxin as well as the histological alterations induced by these venoms. Isolated kidneys from Wistar rats weighing 240 to 280 g were perfused with Krebs-Henseleit solution containing 6 g%...

Placental haemangioma associated with acute fetal anemia in labour.

A case of pregnancy complicated by a placental hemangioma is presented. This was unassociated with any of the complications commonly coexistant with this tumor, and presented with fetal anemia due to a fetomaternal transfusion. ; A case of pregnancy complicated by a placental hemangioma is presented. This was unassociated with any of the complications commonly coexistant with this tumor, and presented with fet...

Gastrojejunocolic fistula. Apropos of 3 consecutive cases.

Apresentam-se 3 casos consecutivos de fístula gastrojejunocólica que se instalaram após gastrectomia segmentar por úlcera duodenal. A sintomatologia mais referida foi de diarreia persistente com fezes contendo restos alimentares e de emagrecimento progressivo mas com apetite conservado, O exame radiológico por clister opaco constituiu o melhor meio de diagnóstico. No período pré-operatório, é essencial uma adeq...
