Diabetic ketoacidosis (DKA) is one of the most serious complications of Diabetes Mellitus (DM) in small animals (SILVA, 2006). It is an acute metabolic disorder, potentially fatal, both in humans and in dogs and cats with DM (BRUYETTE, 1997), being related, mostly, to insulin-dependent diabetics (CHASTAIN, 1981; HUME et al., 2006). DKA is a medical emergency characterized by extreme metabolic abnormalities, including hyperglycemia, metabolic acidosis, ketonemia, dehydration and electrolyte loss (MACINTIRE, 2006) and its diagnosis may be established basically by the detection of ketonuria and metabolic acidosis (NELSON, 2009). The primary purposes of the treatment of DKA are intravascular volume restoration, dehydration, acid-base and electrolyte’s imbalances correction and blood glucose concentration reduction (BOYSEN, 2008). The treatment’s success depends of the clinical status at the time of diagnosis and of the introduction of an appropriate therapy to the conditions of each patient (CHASTAIN, 1981)

O estudo de populações naturais é imprescindível para compreendermos melhor a sua dinâmica, importância no ecossistema, necessidade de recursos, nível de preservação das espécies, entre outras. O cateto (Tayassu tajacu), apesar de possuir ampla distribuição geográfica e ocupar diversos tipos de habitats, pode sofrer alterações no equilíbrio de suas populações devido às grandes pressões sofridas pela caça e alterações ambientais. Vale lembrar que o sucesso reprodutivo de muitas espécies vegetais está ligado à disseminação de frutos e sementes realizada pelo cateto. Considerando a necessidade de preservação das espécies silvestres, a aplicação de metodologias moleculares é uma das formas de sabermos como se encontra a diversidade genética dessas populações e, a partir daí, criarmos medidas para trabalhos conservacionistas. Nesse sentido, o objetivo deste trabalho foi identificar o nível de polimorfismo genético-molecular entre diferentes populações de Tayassu tajacu no Brasil, demonstrando como essas populações, sujeitas a tantas interferências, encontram-se na natureza. Foram analisadas amostras de 17 indivíduos referentes a oito localidades do Brasil (Cascavel - PR, Foz do Iguaçu - PR, Cuiabá - MT, Ariquemes - RO, Rio Branco - AC, Manaus - AM, Belém - PA, e Carajás - PR). O polimorfismo foi identificado com marcadores de RAPD. Foram testados 38 primers, sendo que desses apenas nove forneceram as 30 marcas polimórficas para o estudo. Foi possível notar que a maioria dos indivíduos da mesma população ou de populações próximas não são os mais semelhantes entre si. Indivíduos de localidade distantes, como os de Foz de Iguaçu (PR) e Manaus (AM) mostraram-se mais semelhantes entre si do que com os animais das suas próprias populações. A variabilidade entre os indivíduos...(Resumo completo, clicar acesso eletrônico abaixo)

Osteoarticular diseases are very frequent in small animals, especially dogs. Osteoarthritis is the most common degenerative arthropathy in cats and dogs. It is one of the most important skeletal disease in small animals and it is divided into two broad classes: secondary and genetics. The secondary is originated from situations that can cause joint instability like as trauma, ligament problems and obesity among others. The gene for osteoarthritis comes from hereditary problems such as hip dysplasia, elbow dysplasia and other diseases that can cause articular instability. The hereditary osteoarticular diseases are important only because they can result in the osteoarthritis. It is important to prevent the joint instability and consequently the clinical signs that affect the quality of life of the animals. The most common clinical signs are intermittent claudication, a decrease in performance, reluctance to jump and climb ladders among others. To prevent the clinical signs or mitigate them, the treatments need to be focused on pain control and especially restoration of the affected joint. The treatments most used are the medical and surgery. Anti-inflammatory and analgesics are used in large scale for pain control and to inhibit inflammatory mediators. Furthermore, medical treatment includes weight reduction, physiotherapy and proper nutrition along with anti-inflammatory and analgesics. Surgical treatments are indicated if there is an inadequate response to medical treatment. Physiotherapy is often used in conjunction with other treatments. Besides the reduction of weight is essential and obesity is unacceptable. Cats also suffer from osteoarthritis, but the diagnosis is rarer than in dogs. Usually the cat’s owners relate the reluctance to jump and drop in performance with senility, and when the disease is diagnosed is already in... (Complete abstract click electronic access below)

Due to the importance of traumatic brain injury (TBI) in small animals, this paper aimed to discuss the pathophysiology of the TBI, the pre-hospital and hospital therapeutic procedures, as well as considerations related to transport and initial care of the patient immediately after trauma. The professional must identify the pre-hospital TBI and to treat the victim as a polytraumatized patient, including immobilization. In hospital therapy the procedures of craniotomy are important, especially to remove blood clots. In addition, the use of glucocorticoids must be avoided because of side effects, but combination therapies such as mannitol with furosemide increase the probability of success

Acupuncture is one of the oldest forms of treatment, which is based in the grounds of Traditional Chinese Medicine. Despite the ancient history, it’s not completely widespread in Brazil, neither so comprehensive in veterinary medicine as used in humans. The technique of inserting needles into acupuncture points, can also be stimulated by heat, electrical stimulation or implants of metal, is mainly focused on neuromuscular disorders in small animals. The difficulty of comprehension of language and the lack of cientific bases restricted the possible applications of acupuncture. This work will address some of the clinical situations this complementary treatment can act, such as neurological, cardiorespiratory, reproductive, gastrointestinal, immunological, and postoperative intensive care

O enriquecimento ambiental tem sido proposto como uma prática para melhoria do bem-estar de animais de cativeiro ou de produções zootécnicas. No caso de animais territoriais e agressivos, ao se enriquecer o ambiente, aumenta-se a quantidade de recursos a se defender, bem como o valor do território em disputa, aumentando as interações agressivas. Esse aspecto foi mostrado recentemente para o peixe ciclídeo tilápia-do-Nilo (Oreochromis niloticus). Do ponto de vista comparativo, isso pode ser um fenômeno espécie-específico. Para avaliar isso devemos observar se em condições similares outro peixe ciclídeo sofre a mesma influência do enriquecimento do ambiente. Assim, seguindo a lógica do confronto obtido para tilápia-do-Nilo, aventamos a hipótese de que as atividades agressivas aumentam em função do enriquecimento. Este estudo avaliou essa hipótese para a tilápia do Congo Tilapia rendalli. Como principal resultado, observamos que a latência para iniciar a luta é menor no ambiente enriquecido, mas a frequência de ataques é maior no ambiente não enriquecido (controle). Além disso, observamos clara definição hierárquica por meio da sinalização de submissão (corpo com listras escuras) e dominância (corpo claro sem listras) na condição sem enriquecimento do ambiente. Concluímos que ao contrário da tilápia-do-Nilo, na tilápia do Congo o enriquecimento do ambiente leva a diminuição da agressividade sem clara definição da hierarquia de dominância

Nowadays, in any area that acts within the veterinary medicine, we talk a lot of specialists. Specialists in neurology, cardiology, dermatology, endocrinology, finally, more specialized in a subject, better is the veterinarian. However, on one hand to deepen the knowledge helped in the discovery of new diagnostics and treatments, secondly, a bit lost sight of the patient as a whole. Traditional Chinese medicine, one of whose branches is acupuncture, is aimed at exactly this approach to be fully alive, where all body is interconnected and the disease is not seen as the imbalance of one system, but, as the imbalance between our being and the environment external. Acupuncture is an alternative in the treatment of many diseases, among them Cauda Equina Syndrome, and consists of stimulating specific points on the body surface, which help the body return to its natural harmony. A Cauda Equina Syndrome is a frame subsequent to a neuromuscular spinal cord at the level of the spinal canal of the lower lumbar spine and sacral, whose treatment is almost always surgical. This study aims to show the relevance of acupuncture treatment in this condition and report the importance of the philosophy of traditional Chinese medicine nowadays, even when their arms are not in the treatment of choice

Pythiosis is caused by the oomycetous Pythium insidiosum and affect domestic and wild animals and man. The presence of water and vegetal material is fundamental for its life cycle in nature. The biflagellate zoospore are the infective form of this pathogen. The lesions are generally of granulomatous aspect, which frequently may be contaminated by secondary bacterial infection in skin and subcutaneous tissue. Dissemination to systemic tissues may also occur and it may be due to the spread of the pathogen from cutaneous lesions, as well as a primary source of infection. Clinical signs depend on the affected tissue. Diagnosis of pythiosis is based on the clinical manifestations, histopathological sections and culture of the pathogen. Serological tests may also be employed and more recently molecular biology has been introduced as a sensitive, specific and a rapid method for conclusive diagnosis. Treatment is often difficult and extensive surgery procedures are required, however, depending on the anatomic region and size of the lesion, such procedure is unfeasible and relapses are frequent. Due to the climate changes, which has contributed to increase the incidence of pythiosis, it is necessary the search for new therapeutic protocols

Atualmente o encalhe de filhotes órfãos representa uma das principais ameaças à conservação do peixe-boi marinho (Trichechus manatus manatus) no litoral nordeste do Brasil. O Projeto Peixe-boi resgata os filhotes encalhados, reabilita em cativeiro e reintroduz estes animais em áreas de ocorrência histórica e em locais onde a população está em declínio. Estudos sobre comportamento animal fornecem uma importante ferramenta para avaliação dos Programas de Reintrodução. Os trabalhos existentes sobre comportamento de peixes-boi marinhos em vida livre sujeitos a interações antrópicas restringem-se a animais nativos na Flórida. No Brasil, há estudos etológicos apenas com espécimes em cativeiro ou recinto em ambiente natural. O objetivo do trabalho foi verificar possíveis alterações comportamentais de peixes-boi reintroduzidos, ou seja, que passaram parte da vida em cativeiro e foram soltos em ambiente natural, em função de interações antrópicas. No período de Fevereiro a Julho de 2010, com o auxílio da radio-telemetria, uma fêmea e dois machos (8 anos de idade) foram observados diariamente, em períodos alternados, com a metodologia do “animal focal”. Para o monitoramento, utilizou-se bicicleta, caiaque e, em locais de difícil acesso, o mesmo foi feito a pé. Totalizou-se 114 horas de observação para Arani e 167 horas para Potiguar. As observações da fêmea Aira ficaram comprometidas em função da perda do equipamento de radio-telemetria. A análise dos dados mostrou uma alta freqüência de comportamentos de interação (mais de 50%) em relação aos demais comportamentos de função vital para os dois machos. Dessas interações, as com animais de mesma espécie e objeto atingiram elevadas freqüências. Verificou-se ainda que a categoria afiliativa foi predominante nas interações entre peixes-bois...

Systhemic lupus erythematous is a imunomediated disorder witch affects primarly dogs between two and nine years. Clinical manifestations are very diverse, including renal signs, that may lead to chronic renal disease, and dermatologic and joint sings. Systhemic lupus erythematous diagnostic is a challange to the clinician, due to its diverse list of differecial diagnoses and its low availability of specific tests. The treatment consists of corticosteroids and imunomodulators, and supportive therapy that inhibits the progression of the disease. Monitoring the animal with systhemic lupus erythematous is important, due to its recurrent caracteristic

Together with the increase of environmental degradation in the past few decades, the environmental education (EE) has emerged and grown all around the world. It is worrying the frequent assigning of stereotypes to the animals and the cases of disrespect to them. For these matters it was studied the presence and importance attributed to animals in the annals of six editions of an event of great significance in the field of Environmental Education, the meetings Pesquisa em Educação Ambiental (EPEAs). The animals were chosen for deserving more attention in the preservationist context, besides allowing the use of a great extent of activities in EE, regarding scholar and non-scholar organizations. The articles that presented descriptors related to animals in the title, keywords or abstract were analyzed in depth and characteristics such as segmentation of the studied population, locations where jobs tend to be performed, prevailing aspects and didactic material production, among others, were investigated and compared. It was also verified which current trends on Environmental Education currents are more frequently presented in the EPEAs articles, in order to map the Environmental Education in Brazil in the past few years, using as a basis an important theoretical framework in the area. Through the use of descriptors it was possible to define the articles that would be analyzed in depth, which is less than 6% of the total work published and represents that, until the sixth edition, the EPEAs have a minor amount of works concerning animal matters. In many of these articles animals were superficially worked, which demonstrates the necessity of approaches not only involving more the animals, but also addressing the complex environmental matter. Several trends were identified in various EE currents, coexisting and also conflicting in the field of Brazilian Environmental Education. It was observed, in several cases, two or more trend currents in the ...
