Doenças respiratórios em aves atendidas no Laboratório de Ornitopatologia da FMVZ-UNESP/Botucatu-SP, Brasil, nos anos de 2005 a 2006

The respiratory tract of birds shows anatomical and physiological characteristics that facilitates the occurrence of disease, mainly those of microbiological origin. This article analyzes the frequency of respiratory diseases in domestic and wild birds treated during the years 2005-2006 at the Ornitopathology Laboratory of the Veterinary Hospital, Faculty of Veterinary Medicine and Zootecnics, São Paulo State University (FMVZ-UNESP). Diagnoses were obtained through clinical and radiographic exams as well as haemogram, microbiological culture, parasitological tests and necropsy, being septicemic processes, aspergillosis and mycoplasmosis the most diagnosed diseases. No zoonotic threats were identified, so the entities were described as of low-impact on public health. However, the above mentioned agents can provoke death of birds and difficult for treating and eradication as well.

A relação entre modernização neoliberal e práticas políticas atrasadas no Brasil dos anos 1990

Our goal is to investigate the reasons behind the presence of clientelist-type practices among the popular classes in Brazil, highlighting the decade of the 1990s. Our proposal gives salience to factors regarding the phenomenon's socio-political conjuncture, thereby taking us beyond explanations that rely exclusively on historical-cultural aspects or that sustain an economic bias. We use bibliographic and journalistic sources, from which we develop our own interpretation of the period. Thus, we observe that clientelist practices are encouraged to manifest themselves at the level of national political organization particularly within the federal sphere yet are also reflected at state and municipal levels, due to the coalition of political forces created through the implantation of a neoliberal project in Brazil. The latter has joined modern Brazilian social democracy and old regional oligarchies situated primarily within the PFL, PP, PTB and certain sectors of the PMDB, whose representatives are known for their attachment to patrimonialist and paternalistic practices. The inclusion of the latter in the conservative pact that has promoted neo-liberal political reform has thus meant awarding new value to such practices. Herein lies partial explanation for the vigor with which practices such as fisiologismo, apadrinhamento, abuse of state machinery, buying and selling of votes and clientelism have manifested themselves on the national scene over the course of the 1990s.

Azul de metileno no tratamento da síndrome vasoplégica em cirurgia cardíaca. quinze anos de perguntas, respostas, dúvidas e certezas

Objective: There is strong evidence that methylene blue (MB), an inhibitor of guanylate cyclase, is an excellent therapeutic option for vasoplegic syndrome (VS) treatment in heart surgery. The aim of this article is to review the MB's therapeutic function in the vasoplegic syndrome treatment. Methods: Fifteen years of literature review. Results: 1) Heparin and ACE inhibitors are risk factors; 2) In the recommended doses it is safe (the lethal dose is 40 mg/ kg); 3) The use of MB does not cause endothelial dysfunction; 4) The MB effect appears in cases of nitric oxide (NO) up-regulation; 5) MB is not a vasoconstrictor, by blocking of the GMPc system it releases the AMPc system, facilitating the norepinephrine vasoconstrictor effect; 6) The most used dosage is 2 mg/kg as IV bolus followed by the same continuous infusion because plasmatic concentrations strongly decays in the first 40 minutes; 7) There is a possible window of opportunity for the MB's effectiveness. Conclusions: Although there are no definitive multicentric studies, the MB used to treat heart surgery VS, at the present time, is the best, safest and cheapest option, being a Brazilian contribution for the heart surgery.

Morfologia de sementes e de estádios iniciais de plântulas de espécies de Bromeliaceae da Amazônia

Seeds of Aechmea bromeliifolia, A. castelnavii (Bromelioideae); Dyckia duckei, D. racemosa (Pitcairnioideae) and Tillandsia adpressiflora (Tillandsioideae) were collected in the Amazon regions (Mato Grosso) and studied to describe morphological characterization and post-seminal development, which can be taxonomically useful, and to assess percent germination. All the species have epigeous germination and produce cryptocotyledonary plantlets. Seeds have no dormancy and percent germination is high (over 86%), which facilitates the production of seedlings and conservation studies. Exclusive characteristics of the genera include: the seed coat of Aechmea (Bromelioideae) has mucilage that prevents desiccation; whereas that of Dyckia (Pitcairnioideae) has membranaceous wings and that of Tillandsia (Tillandsioideae) has feathery appendages, both of which make dispersal easier and establish the epiphytic habit. Initial post-seminal development of Aechmea (Bromelioideae) and Dyckia (Pitcairnioideae) is marked by the emergence of primary roots, interpreted as a basal character, whereas that of Tillandsia adpressiflora (Tillandsioideae) is marked by the emergence of the cotyledon, interpreted as a derived character. Dyckia and Tillandsia have a small tank only in the seedling phase while the contrary occurs in Aechmea.
