Thrombocytopenia and platelet hypoaggregation induced by Bothrops asper snake venom Toxins involved and their contribution to metalloproteinase-induced pulmonary hemorrhage

Thrombocytopenia and platelet dysfunction occur in patients bitten by Bothrops sp snakes in Latin America. An experimental model was developed in mice to study the effects of B. asper venom in platelet numbers and function. Intravenous administration of this venom induces rapid and prominent thrombocytopenia and ex vivo platelet hypoaggregation. The drop in platelet numbers was primarily due to aspercetin, a protein of the C-type lectin family which induces von Willebrand factor-mediated platelet aggregation/agglutination. In addition, the effect of class P-III hemorrhagic metalloproteinases on the microvessel wall also contributes to thrombocytopenia since jararhagin, a P-III metalloproteinase, reduced platelet counts. Hypoaggregation was associated with the action of procoagulant and defibrin(ogen)ating proteinases jararacussin-1 (a thrombin-like serine proteinase) and basparin A (a prothrombin activating metalloproteinase). At the doses which induced hypoaggregation, these enzymes caused defibrin(ogen)ation, increments in fibrin(ogen) degradation products and D-dimer and prolongation of the bleeding time. Incubation of B. asper venom with batimastat and α 2-macroglobulin abrogated the hypoaggregating activity, confirming the role of venom proteinases in this effect. Neither aspercetin nor the defibrin(ogen)ating and hypoaggregating components induced hemorrhage upon intravenous injection. However, aspercetin, but not the thrombin-like or the prothrombin-activating proteinases, potentiated the hemorrhagic activity of two hemorrhagic metalloproteinases in the lungs. © 2005 Schattauer GmbH, Stuttgart.

Caracterização histomorfológica de lesões granulomatosas sugestivas de tuberculose ganglionar e pulmonar em bovinos abatidos na região noroeste do estado de SãoPaulo

Tuberculosis infection among humans transmitted by products of animal origin can be caused by Mycobacterium bovis, a concern in developing countries, because the number of human cases is relatively high compared with countries that have implemented programs to eradicate bovine tuberculosis for many years. Because it is a chronic disease with subclinical evolution, it is transmitted to other animals in the herd livestock resulting in high loss losses resulting high (10 to 25%), as well as the zoonotic nature of the disease on public health. This work aimed to study the histomorphology of granulomas in samples of lymph nodes and lungs of animals with suggestive lesions of tuberculosis, as well as those similar to the sanitary inspection. The animals clinically healthy ante-mortem, were slaughtered in a slaughterhouse in the northwestern state of Sao Paulo between April 2008 and April 2009, considering that carcasses had lymph nodes with lesions typical of tuberculosis, exhibiting nodular and hemorrhagic appearance. The caseous or calcified lesions, purulent or not, of various sizes and shapes, were also evaluated. Of the 307,661 animals slaughtered in the mentioned period, 494 gross suggestive lesions of tuberculosis and from 29 cities in the state of Sao Paulo, 16 from Mato Grosso do Sul, Goias 15, one from Mato Grosso and Paraná. Among these, 200 samples (40,5%) were processed for histopathological evaluation by hematoxylin-eosin (HE) and 90 (45%) were subjected to Ziehl-Neelsen (ZN) and examined by light microscopy. In HE staining, histopathological changes of tuberculosis were found in 197 (98,5%), classified according to the stage of development adopted by Wango et al.(31), where 29 samples were included in stage I (14,5%), 53 in stage II (26,5%), 87 in stage III (43,5%), 28 in stage IV (14%). In the ZN staining Mycobacterium sp was found in 89 (99%) of the specimens. The rate of tuberculosis in the herd studied was 0,16%. We conclude that the identification of the disease in slaughterhouses and meat companies from significant gross lesions, enables the implementation of effective measures, specifically the origin of the disease in cattle herds, providing control measures to prevent its spread.

Tolerance and nutritional therapy of dietary fibre from konjac glucomannan hydrolysates for patients with inflammatory bowel disease (IBD)

Carbohydrates may provide an alternative therapeutic approach for a number of digestive health disorders such as inflammatory bowel disease (IBD). The aim of this work was to characterise the tolerance and efficacy of low and high molecular weight konjac glucomannan hydrolysates within healthy volunteers and patients suffering from IBD and associated gut conditions. These conditions included constipation, Crohn's disease and ulcerative colitis. For general tolerance, fourteen patients participated whilst for the digestive disorder trial, there were twenty. Scores of taste/texture of the product, bowel movement, stool consistency, diarrhoea, existence/absence of blood in the faeces, abdominal pains, flatulence, vomiting, fever, improvement of life style after use, willingness to use in the future and clinician's statements about each patient's conditions before and after use were recorded. The results showed that the hydrolysates were tolerated well for patients with diarrhoea and had a significant improvement on bowel movement, stool consistency, abdominal pain and flatulence after ten days. With respect to effects on IBD, there was a significant health benefit after fourteen days of consumption for bowel movement, stool consistency, diarrhoea, existence/absence of blood in the faeces, abdominal pain, flatulence and vomiting. Most patients declared an improvement of their life style after consuming the hydrolysates. The use of konjac glucomannan hydrolysates as a therapeutic agent or adjunct to standard treatments could prove a successful tool for the treatment of a range of disorders; although large scale studies are required to characterise further the role of the carbohydrates.

Malignant epitheliod hemangioendothelioma of the thyroid: a case report

Primary malignant epithelioid hemangioendothelioma (MEH) of the thyroid is a rare neoplasia with only a few cases reported in the literature. We report a 75 year old man, who presented with a substernal goiter and compressive symptoms. Ultrasonographic evaluation revealed a hypoechogenic nodule in the left lobe, measuring 4.1 cm in maximum diameter, and associated gross calcifications. Fine needle aspiration yielded hemorrhagic material. A left thyroid lobectomy and isthmusectomy was performed. The surgical specimen contained a malignant epithelioid hemangioendothelioma measuring 6 x 4 x 3 cm that had infiltrated about 50% of the thyroidal parenchyma, and surrounded a necrotic nodule. Immunohistochemistry results corroborated the histopathological findings; staining was positive for AE1/AE3, CD31, CD34, factor VIII-related antigen, and Ki-67 expression. Because of the patient’s comorbidities, surgical complementation was not undertaken and he has been undergoing conservative treatment.

Hyperacute necrotizing pneumonia and septicaemia caused by to Clostridium perfringens in Cervus timorensis: case report

Clostridia are uncommon causes of pleuropneumonia in wildlife In human and domestic animals,different hemorrhagic pneumonia with involvement of the pleura. In livestock, most cases are associated with sudden changes of diet, iatrogenic lesionscaused by invasive procedures such as thoracente thoracotomy, or traumatic percutaneous introduction of the microorganism.The clinical course of pleuropneumonia by clostridia infections may be very variable, although usually are associated with hyperacute or acute course and high mortality. The pr necrotizing pneumonia and sepsis caused by hyperacute fatal course, highlighting clinical, epidemiological, microbiological, and histopathological aspects.
