Chewing insects, pollinators, and predators on Acacia auriculiformis A. Cunn. ex Beth (Fabales: Fabaceae) plants fertilized with dehydrated sewage sludge / Insetos mastigadores, polinizadores e predadores em plantas de Acacia auriculiformis A. Cunn. ex Beth (Fabales: Fabaceae) fertilizada com lodo de esgoto desidratado

Fertilization with dehydrated sewage sludge can speed up the recovery process of degraded areas due to nutrients concentration, favoring the development of pioneer plants such as Acacia auriculiformis A. Cunn. ex Beth (Fabales: Fabaceae) and the emergence of insects. This study aimed the evaluation of chewing, pollinating insects, predators, their ecological indices and relationships on A. auriculiformis plants fertilized with dehydrated sewage sludge. The experimental design was completely randomized with two treatments (with and without dehydrated sewage sludge) and 24 repetitions. The prevalence of chewing insects Parasyphraea sp. (Coleoptera: Chrysomelidae), Nasutitermes sp. (Blattodea: Termitidae), and Tropidacris collaris (Stoll, 1813) (Orthoptera: Romaleidae), defoliation, and ecological indices of abundance of Coleoptera and Orthoptera were observed on fertilized A. auriculiformis. Acacia auriculiformis plants, with a superior number of branches/tree, revealed greater abundance of Coleoptera and Orthoptera, species richness of pollinating insects, defoliation, numbers of Parasyphraea sp. and T. collaris. The ones with larger leaves/branches displayed greater abundance of species richness of Coleoptera and Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae). Therefore, the use of A. auriculiformis plants, fertilized with dehydrated sewage sludge, is promising in the recovery of degraded areas due to the ecological indices increase of chewing and pollinators insects and spiders in the analyzed area.

O objetivo deste trabalho foi avaliar os insetos mastigadores, polinizadores e predadores e seus índices e relações ecológicas em plantas de A. auriculiformis fertilizadas com lodo de esgoto desidratado, em área degradada, durante 24 meses. O delineamento foi inteiramente casualizados com dois tratamentos (com e sem adubação com lodo de esgoto desidratado) e 24 repetições (uma repetição = uma planta). O maior número de insetos mastigadores Parasyphraea sp. (Coleoptera: Chrysomelidae), Nasutitermes sp. (Blattodea: Termitidae) e Tropidacris collaris (Stoll, 1813) (Orthoptera: Romaleidae), de desfolha, e do índice ecológico abundância de Coleoptera e de Orthoptera foram maiores em plantas de A. auriculiformis fertilizadas do que nas não fertilizadas com lodo de esgoto desidratado. Plantas de A. auriculiformis, com maior quantidade de galhos/árvore, apresentaram maiores abundâncias de Coleoptera e Orthoptera, riqueza de espécies de insetos polinizadores, desfolha e números de Parasyphraea sp. e T. collaris, e as com maior folhas/galho os de riqueza de espécies de Coleoptera e Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae). Por tanto, a utilização de A. auriculiformis, adubada com lodo de esgoto desidratado, é promissora na recuperação de áreas degradadas devido ao aumento dos índices ecológicos de insetos mastigadores, polinizadores e aranhas na área.

Osteossíntese femoral associada ao biovidro 60S em tamanduá-bandeira: relato de caso / Femoral osteosynthesis associated with 60s bioglass in tamanduá bandeira: case report

Atropelamentos de animais silvestres são frequentes e muitas vezes causam fraturas ósseas que, se não tratadas adequadamente, levam à morte do animal por complicações ou por inabilidade de sobrevivência no seu habitat natural. O objetivo do presente trabalho foi relatar o uso de placa associada ao pino intramedular e ao biovidro 60S (BV60S) para o tratamento de fratura de fêmur em tamanduá-bandeira. O animal foi resgatado pela polícia ambiental com suspeita de atropelamento. Foi sedado para avaliação clínica e radiográfica, que revelou fratura em fêmur direito. Utilizou-se dexmedetomidina como medicação pré-anestésica, midazolam e cetamina para indução, e isoflurano para manutenção. Também foi realizado bloqueio peridural com bupivacaína e morfina. A osteossíntese foi feita com placa bloqueada 2,7 e pino intramedular 2,5. Colocaram-se 4g de BV60S no foco de fratura para favorecer a osteogênese. O paciente teve recuperação funcional imediata do membro acometido. A reparação óssea ocorreu por segunda intenção, observando-se ossificação completa do calo com consolidação clínica, aos 30 dias, e remodelação quase completa, aos 180 dias. Conclui-se que o uso de placa e pino associado ao BV60S é eficiente no tratamento de fratura de fêmur em tamanduá, permitindo a rápida recuperação e a reintrodução do animal na natureza.(AU)

Roadblocks of wild animals are frequent and often cause bone fractures that if not properly treated lead to the death of the animal due to complications or inability to survive in its natural habitat. The objective of the present study was to report the use of plate rod and bioglass 60S (BG60S) for the treatment of femoral fracture in anteater. The animal was rescued by environmental police on suspicion of being hit. It was sedated for clinical and radiographic evaluation, which revealed a fracture in the right femur. Dexmedetomidine was used as preanesthetic medication, midazolam and ketamine for induction, and isoflurane for maintenance. Epidural blockade with bupivacaine and morphine was also performed. Osteosynthesis was done with a locking plate 2.7 and 2.5 intramedullary pin. 4G of BG60S was placed in the focus of fracture to favor osteogenesis. The patient had immediate functional recovery of the affected limb. The bone repair occurred by second intention, with complete ossification of the callus with clinical consolidation at 30 days, and near complete remodeling at 180 days. It is concluded that the use of plate rod to the BG60S is efficient in the treatment of femur fracture in anteater, allowing the rapid recovery and reintroduction of the animal in the wild.(AU)

Use of a GnRH synthetic analog (buserelin) for estrous induction in female dogs / Utilização de análogo sintético de GnRH (buserelina) na indução do estro em cadelas

The aim of this study was to evaluate the effectiveness of a GnRH synthetic analog, as an estrous inducer in female dogs when administered during the anestrous phase, and to evaluate the pregnancy rate achieved through natural copulation. For this purpose, ten female dogs of different breeds were used. The subjects received buserelin by intramuscular injections at a dose of 2,1mcg when female dogs weighed up to 10kg (Group 1) and of 4,2mcg when the dogs weighed above 10kg (Group 2). Of the ten subjects, only three presented estrus after a single injection of buserelin: two dogs from Group 1 and one dog from Group 2 on average 7±1.29 days. The remaining seven dogs were given a second dose of buserelin, equal to the first administration. Of these, three belonged to Group 1 and four to Group 2. Four of these dogs exhibited clinical signs of estrus within, on average 9±7.3 days from the second injection. The seven female dogs that did enter estrus were fertilized successfully through natural copulation. The administration of buserelin was effective in inducing estrus in female dogs during the anestrous phase, with a maximum of two administrations.(AU)

Objetivou-se avaliar a eficácia de um análogo sintético ao GnRH como indutor de estro em cadelas em anestro e a taxa de prenhez por meio de cópula natural. Para isso, foram utilizadas 10 fêmeas caninas de diferentes raças. Cadelas de até 10kg de peso (grupo 1) foram submetidas à administração de buserelina por via intramuscular, na dose de 2,1mcg, e cadelas acima de 10kg (grupo 2) foram submetidas à mesma medicação, porém na dose de 4,2mcg. Das fêmeas em anestro, apenas três apresentaram estro com apenas uma aplicação, sendo duas do grupo 1 e uma do grupo 2, em 7±1,29 dias, em média. Em sete cadelas foi administrada mais uma dose de buserelina; destas, quatro eram pertencentes ao grupo 2 e três eram do grupo 1. Os sinais de estro ocorreram, em média, após 9±2,73 dias da segunda aplicação. As sete cadelas que manifestaram estro foram fertilizadas por meio de cópula natural. A administração de buserelina é eficiente para a indução de estro, em cadelas em anestro, em, no máximo, duas aplicações.(AU)

Parâmetros genéticos para características produtivas e biométricas em abelha Melipona quadrifasciata anthidioides LEPELETIER / Genetic parameters for production and biometrics traits in honey bee Melipona quadrifasciata anthidioides LEPELETIER

Os objetivos deste trabalho foram estimar componentes de variância genética aditiva, fenotípica e residual e a herdabilidade para características relacionadas com a produção de mel e com a estrutura do ninho de abelhas Melipona quadrifasciata anthidioides. Sessenta colônias de diferentes regiões da Bahia foram transladadas para caixas padronizadas modelo INPA e divididas, originando as gerações parentais G1 e G2. Foram medidas as características: estimativa da produção de mel; número, largura, volume e altura dos potes de mel; número, altura e diâmetro dos potes de pólen; peso; número, largura e diâmetro dos discos de cria e estimativa da população da colônia. As medidas foram corrigidas para o efeito fixo de mês de mensuração. Os componentes de variância e herdabilidade foram estimados por meio do método de semelhança entre parentes, utilizando-se abordagem Bayesiana. As médias e os desvios padrão variaram de 2,01±0,70cm para diâmetro de potes de pólen a 2.333,0±384,1kg para o peso das caixas. Houve indicação de convergência para todas as cadeias obtidas. As estimativas de variância genética aditiva variaram de 0,02cm para as características largura dos potes de mel a 38.587,72kg para o peso. Para as estimativas de variâncias fenotípicas, os valores variaram de 0,05 para a altura dos potes de pólen a 95.136,43kg para o peso; e para as variâncias residuais, os valores encontrados variaram de 0,02 para a variável largura dos potes de mel a 56.548,71kg para o peso. As estimativas de herdabilidade variaram de 0,35 a 0,53. Os resultados demonstraram que as características avaliadas possuem variação genética aditiva que garante boa resposta à seleção.

The aim of this study was to estimate components of genetic variance, phenotypic and residual and heritability for traits related to the production of honey and the nest structure of bee Melipona quadrifasciata anthidioides. Sixty colonies from different regions of Bahia were transferred to standard INPA model boxes and divided, creating the parental generations G1 and G2. The following characteristics were measured: estimated production of honey, number, width, height and volume of the honey pots, number, height and diameter of pollen storage pots, weight, number, length and diameter of the brood combs and estimate the population of the colony. The measurements were corrected for the fixed effects of month of measurement. The variance components and heritability were estimated by the method of similarity between relatives using the Bayesian approach. The mean and standard deviations ranged from 2.01±0.70cm diameter pots for pollen to 2333.0±384.1kg to the weight of the boxes. There was indication of convergence for all the chains obtained. Estimates of the additive genetic variance ranged from 0.02cm to the width characteristics of honey pots to 38587.72kg for weight. For the estimates of phenotypic variance the values ranged from 0.05 for the height of the pollen pots to 95136.43kg for weight; and the residual variance the values varied from 0.02 for the variable width of the honey pots to 56548.71kg for weight. The results showed that the characteristics assessed have additive genetic variation that ensures good response to selection.

Evaluation of apoptosis as a mechanism of follicular cell atresia in the ovaries of cattle (bos indicus) and buffalo (bubalus bubalis) fetuses

The objective of this study was to investigate the occurrence of apoptosis in the ovaries of cattle and buffalo fetuses between 4 and 8 months old by the terminal deoxynucleotidyltransferase - mediated dUTP nick end labeling (TUNEL) assay . Histological analysis of the ovarian t issue showed that apoptosis occurred at all ages evaluated , presenting a similar pattern among different fetal stages in both species . Within species, secondary follicles displayed a higher (P 0.05) of apoptotic follicular cells among the three follicular classes compared . C omparing resul ts between species, secondary follicles had a higher (P < 0.05) mean number of TUN EL positive cells in bovine fetuses; however , this difference was proportional to the larger number of follicular cells present in secondary follicles in this species . In summary, the TUNEL method was effective for the detection of apoptosis in the support ing cells of ovarian follicles from bovine and buffalo fetuses with apoptosis occurring at similar rates in both species between 4 and 8 months of gestational age. Further studies are needed to better understand the dynamics of apoptosis as a regulator of follicular atresia in fetal ovaries from these species, as well as the potential involvement of the oocyte in this process.

Leishmania (Viannia) braziliensis is the main species causing cutaneous leishmaniasis in the Federal District of Brazil

The first autochthonous case of American cutaneous leishmaniasis was reported in the Federal District in 1980, and the species involved in this type of leishmaniasis was unknown. This study aimed to identify the species that causes the disease in the Federal District and to investigate its clinical and epidemiological aspects. Between 2000 and 2007, 71 autochthonous cases of leishmaniasis were reported in the Federal District. Leishmania species were identified by means of direct immunofluorescence reactions using monoclonal antibodies and restriction fragment length polymorphism. The species of 40 (56.33%) out of 71 samples were identified. Thirty-six (90%) were identified as Leishmania (Viannia) braziliensis and four (10%) were identified as Leishmania (Leishmania) amazonensis. In this area, the disease had clinical and epidemiological characteristics similar to those found in other Brazilian regions.

DNA identification of Leishmania (Viannia) braziliensis in human saliva from a patient with American cutaneous leishmaniasis

This study aims to report the amplification of the DNA of Leishmania (V.) braziliensis, using polymerase chain reaction, obtained from the saliva of a patient with American cutaneous leishmaniasis who did not present any lesion in the oral mucosa. Amplification produced fragments of 103 bp, an estimated size employing Leishmania (V.) braziliensis primers (b1 e b2). The present results revealed, for the first time, that the in vitro amplification of Leishmania DNA using samples from the salivary fluid of a patient with American cutaneous leishmaniasis is possible. However, more studies are required with a larger number of participants to evaluate the usefulness of saliva as a non-invasive sample for PCR. The development of such non-invasive technique is necessary for the diagnosis of many diseases in the future, especially infectious and parasitic ones.

Calagem e adubação orgânica na produção de biomassa e óleo essencial em Lippia citriodora (Kunth) / Liming and organic fertilization on Lippia citriodora (Kunth) phytomass and essential oil production

O presente trabalho objetivou avaliar a calagem e adubação orgânica na produção de biomassa e óleo essencial em Lippia citriodora Kunth. O delineamento experimental utilizado constou de fatorial 7 x 2, sendo sete tratamentos (testemunha; adição de sulfato de Ca e Mg; calcário dolomítico; silicato de Ca e Mg; sulfato de Ca e Mg + esterco de curral; calcário dolomítico + esterco de curral; silicato de Ca e Mg + esterco de curral) e duas épocas de colheita, com quatro repetições, inteiramente casualizado (DIC). Verificou-se que a correção do solo mostrou-se prática necessária para o desenvolvimento da Lippia citriodora. Independentemente da época de colheita, a produção de massa fresca e seca foi maior com a aplicação do esterco de curral (32 t ha-1), no entanto, isso não refletiu em maior rendimento de óleo essencial.

The present work aimed to evaluate the effect of liming and bovine fertilization on Lippia citriodora Kunth phytomass and essential oil production. The experimental design was completely randomized with seven treatments (control; Ca and Mg sulfate; limestone; Ca and Mg silicate; Ca and Mg sulfate + manure; limestone + manure; Ca and Mg silicate + manure) and two harvest seasons, with four replicates. Soil adjustment showed to be a necessary procedure for Lippia citriodora development. Independently of the harvest season, fresh and dry matter yields were higher under treatments with bovine manure (32 t ha-1); however, no effect of treatments was observed on essential oil concentration.

Parâmetros hematológicos de jumentas gestantes em diferentes períodos / Hematological parameters of pregnant donkeys in different periods

The hematological parameters and total protein concentration in healthy donkeys during pregnancy, under grass handling conditions in tropical weather, were evaluated. Fifth-two Marchador Brasileiro breed healthy donkeys, ranging from 8 to 16 years old, were evaluated, 36 of which were pregnant. The animals were separated in four groups: non pregnant (control), pregnancy from 25 to 110 days (first phase), from 111 to 210 days (second phase), and from 211 to 340 days (third phase). Total protein, erythrocyte, and leukocytes counts; packed cell volume; hemoglobin concentration; hematimetric absolute rates of mean corpuscular volume (MCV); mean corpuscular hemoglobin (MCH); and mean corpuscular hemoglobin concentration (MCHC) were evaluated. Total protein and eosinophils count decreased in the first phase. Red blood cells, hemoglobin concentration, and MCHC increased in the third phase of pregnancy. However, MCV and MCH decreased in the same phase.

Adenocarcinoma de células glassy de colo de útero em paciente jovem com HPV: relato de caso / Glassy cells adenocarcinoma of the uterine cervix in young patient with HPV: case report

Introdução: o câncer de colo uterino é a segunda neoplasia mais comum em mulheres no mundo e a terceira entre a população feminina brasileira. O HPV desempenha um importante papel no desenvolvimento de neoplasias cervicais, estando presente em 95% dos casos de câncer de colo de útero. O carcinoma de células glassy é um carcinoma adenoescamoso misto pouco diferenciado, raro, de comportamento agressivo e altamente resistente à radioterapia. Atinge tipicamente mulheres jovens, com pico de incidência entre a 3a e a 4a década de vida. Está associado aos tipos 16 e 18 de HPV e sua evolução é aceleradana gravidez. O tempo médio de sobrevida após o diagnóstico é de 10 meses. Relato de caso: mulher, 26 anos, multípara, com história prévia de condiloma acuminado, apresentou lesões genitais que agravaram em sua última gestação, tendo evoluído com massas exofíticas diagnosticadas como carcinoma de células glassy, com curso agressivo e metástases precoces, não responsivo à radioterapia e progressão ao óbito em 16 meses. Conclusão: o carcinoma de células glassy destaca-se pela agressividade e rapidez de seu desenvolvimento, levando ao óbito mulheres jovens, em idade fértil e produtiva. Diante da sua baixa resposta às terapias antineoplásicas, destaca-se a importância de sua prevenção, seu diagnóstico e tratamento precoces, possíveis mediante o usode preservativos, da vacina contra o HPV e do exame colpocitológico regular, com coleta de material endocervical e acompanhamento eficaz.

Introduction: cervical cancer is the second most common cancer in women worldwide and the third among the female population in Brazil. HPV plays an important role in the development of cervical cancer, being present in 95% of cases of cancer of the cervix. Glassy cells carcinoma is a poorly differentiated mixed adenosquamous carcinoma, rare, aggressive and highly resistant to radiotherapy. It typically affects young women, with peak incidence between the third and fourth decades of life. It is associated with types 16 and 18 of HPV and its evolution is acelerated during pregnancy. The average survival time after diagnosis is 10 months.Case Report: woman, 26 years old, multiparous, with a history of condyloma acuminata, genital lesions that had increased in their last pregnancy, having evolved with exophytic masses diagnosed as glassy cell carcinoma, and aggressive course with early metastases not responsive to radiation therapy and progression to death in 16 months. Conclusion: glassy cells carcinoma is distinguished by aggressiveness and speed of its development, leading child-bearing age and productive young women to death. In view of its low response to anticancer therapies, we highlight the importance of its prevention, early diagnosis and treatment, possible through the use of condoms, the vaccine against HPV and cervical cytology at regular collection of endocervical material and effective monitoring.

Predicting mobility gains among children with cerebral palsy after application of botulinum toxin A / Predizendo ganhos de mobilidade em crianças com paralisia cerebral após aplicação de toxina botulínica A

BACKGROUND: Botulinum toxin A (BTA) is commonly used to treat children with cerebral palsy (CP). However, the variables measured before BTA application and associated with motor function and independent mobility, known as predictors of functional outcomes, have not been well defined. OBJECTIVE: To identify clinical predictors of gains in functional motor skills and independence of mobility among children with CP, three and six months after BTA application. METHODS: This was a convenience sample of children with spastic CP (n=35). Measurements of quantitative gains in motor skills and independence of mobility were taken three and six months after BTA application. These outcomes were observed through repeated applications of two functional tests: GMFM (Gross Motor Function Measure) and PEDI (Pediatric Evaluation of Disability Inventory). These tests evaluated gross motor function while sitting or standing and during transitions between these postures, and also during dynamic activities such as walking, running and jumping, along with the children's independence in mobility tasks. The independent variables included the children's characteristics such as age, severity, topographic diagnosis, neuromuscular-skeletal parameters (range of motion and spasticity), gait quality and performance in the functional tests before BTA. RESULTS: Four predictive models were developed (R² between 0.58 and 0.83; p<0.05) through the use of CART analysis: two at three months and two at six months after BTA application. The results indicated that children with better gait quality, smaller repertoire of functional motor skills, less independence of locomotion and age below four years and six months before BTA presented greater gains in motor skills and independence in mobility. CONCLUSION: The results identified significant clinical parameters that can predict functional outcomes of BTA applications among children with CP.

CONTEXTUALIZAÇÃO: A toxina botulínica A (TBA) é comumente utilizada em crianças com paralisia cerebral (PC), entretanto preditores de desfechos funcionais, ou seja, variáveis mensuradas pré-aplicação da TBA e associadas a ganho na função motora e independência na mobilidade não são bem definidos. OBJETIVO: Identificar preditores clínicos de ganho em habilidades motoras funcionais e independência em mobilidade em crianças com PC, aos três e seis meses pós-aplicação de TBA. MÉTODOS: Amostra de conveniência de crianças com PC espástica (n=35). As medidas incluíram: melhora quantitativa nas habilidades motoras e na independência em mobilidade aos três e seis meses após a aplicação da TBA. Esses desfechos foram observados por meio de aplicações repetidas dos testes funcionais GMFM (Gross Motor Function Measure) e PEDI (Pediatric Evaluation of Disability Inventory). Esses testes avaliaram a função motora grossa durante a manutenção e transições entre as posturas sentada e de pé, além de atividades dinâmicas como andar, correr e pular, e a independência da criança em tarefas de mobilidade. As variáveis independentes incluíram características das crianças como idade, severidade e diagnóstico topográfico, parâmetros neuromusculoesquelético (amplitude de movimento, espasticidade), qualidade da marcha e desempenho nos testes funcionais antes da TBA. RESULTADOS: Foram gerados quatro modelos preditivos (R² entre 0,58 e 0,83; p<0,05), dois aos três e dois aos seis meses após a aplicação da TBA, a partir da análise CART. Os resultados indicaram que crianças com melhor qualidade da marcha, menor repertório de habilidades da função motora, menor independência na locomoção e idade menor que quatro anos e seis meses pré TBA apresentaram maior ganho de habilidades motoras e de independência em mobilidade. CONCLUSÃO: Os resultados identificaram parâmetros clínicos importantes de serem documentados em crianças com PC submetidas à aplicação da TBA para predizer...

The aim of this work was to study the effects of organic fertilization and mulching on phytomass production and total flavonoid content in calendula plants. The experiment was carried out at Federal University of Minas Gerais, Montes Claros Campus. The experimental design was in randomized blocks, in 2x2x4 factorial arrangement, with four replicates: two harvest periods, presence or absence of mulching, and four levels of organic fertilizer (0, 30, 60 and 90 t ha-1). The highest phytomass and total flavonoid productions were obtained with increasing levels of organic fertilizer. The highest total flavonoid content was obtained in the second harvest in the presence of mulching.

Influência da heparina sódica na ocorrência de laminite eqüina induzida por sobrecarga de carboidratos / Influence of heparin in occurrence of carbohydrate overload-induced equine laminitis

Avaliou-se a eficiência da infusão intravenosa de heparina sódica (100UI/kg/8h, a partir de 24h após o fornecimento de carboidrato, até completar 48h) no controle da laminite eqüina experimentalmente induzida por sobrecarga de carboidrato (17,6g de amido de milho/kg de peso corpóreo). Foram utilizados 15 eqüinos adultos, distribuídos em três grupos experimentais: GI (grupo-controle); GII (grupo laminite) e GIII (grupo laminite+heparina). Posteriormente ao fornecimento de carboidrato, os animais foram submetidos a exames físicos e laboratoriais durante um período de 48 horas. Ao final do experimento, os animais foram submetidos à eutanásia pela aplicação intravenosa de 5ml de maleato de acepromazina seguida de 1g de tiopental sódico e 1 litro de solução saturada de KCl para a obtenção de amostras de tecidos dos cascos, necessárias ao exame histológico. Os animais de GII e GIII, submetidos à sobrecarga de carboidratos, desenvolveram laminite, exibindo claudicação 12 e 24h após o fornecimento de carboidrato, respectivamente, bem como aumentos da freqüência cardíaca e do tempo de preenchimento capilar. As alterações histológicas, semelhantes em GII e GIII, eram do tipo degenerativo, como adelgaçamento de lâminas epidérmicas, retração, achatamento e deslocamento de lâminas dérmicas, vacuolização epidérmica e desorganização do tecido epidérmico. A infusão da heparina sódica não preveniu ou atenuou a degeneração laminar.

The efficacy of intravenous heparin administration (100UI/kg/8h, from 24 to 48h after carbohydrate administration) in the control of carbohydrate overload-induced equine laminitis (17.6g of corn starch/kg live weight) was evaluated. Fifteen horses were allocated into three experimental groups: GI (control group), GII (laminitis group), and GIII (laminitis+heparin group). These animals were submitted to physical and laboratorial examination during 48h. After that time, they were euthanized with intravenous administration of 5ml of acepromazine followed by 1g of thiopental sodium and 1 liter of saturated solution of KCl to obtain hoof tissues samples for histological examination. GII and GIII horses developed laminitis, showing lameness 12 and 24h after carbohydrate administration, respectively, as well increased heart rate and capillary refill time. The histological alterations, similar in GII and GIII, were degenerative lesions, as thinness of epidermal lamina, retraction, flattening and dislocation of the dermal lamina, epidermal vacuolization, and disruption of the epidermal tissues. The occurrence of laminar degeneration was not prevented or attenuated with intravenous heparin administration.

Um olhar sobre as LER/DORT no contexto clínico do fisioterapeuta / A look into Repetitive Strain Injury/Work-Related Musculoskeletal Disorders within physical therapists' clinical context

OBJETIVO: Conhecer as representações do fisioterapeuta a respeito das Lesões por Esforços Repetitivos/Distúrbios Osteomusculares Relacionados ao Trabalho (LER/DORT) e analisar como essas representações interferem na prática clínica desses profissionais. MÉTODOS: O estudo foi realizado numa abordagem qualitativa, e os recursos metodológicos foram entrevista semi-estruturada e observação não-participante. A teoria das representações sociais e a epistemologia comparativa serviram como referenciais teóricos. Participaram do estudo 14 fisioterapeutas da cidade de Divinópolis, Minas Gerais. RESULTADOS: a representação dos fisioterapeutas sobre LER/DORT e o doente foi elaborada coletivamente, com base na realidade cotidiana, e configurou-se entre os entrevistados um estilo de pensamento reducionista, com uma concepção mecanicista do organismo humano. CONCLUSÕES: não basta concentrar esforços na tentativa de restaurar o funcionamento normal do corpo se as demandas do paciente são desconsideradas. O conhecimento técnico-científico do fisioterapeuta deve ser conciliado com a expressão subjetiva do paciente na busca de estratégias de intervenção mais eficazes.

OBJECTIVE: To understand physical therapists' representations regarding Repetitive Strain Injury/Work-Related Musculoskeletal Disorders (RSI/WRMSD) and to analyze how these representations interfere with the clinical practice of these professionals. METHODS: The study took a qualitative approach, and the methodological tools were semi-structured interviews and non-participatory observation. The theory of social representations and comparative epistemology served as the theoretical foundations for the study. Fourteen physical therapists from the city of Divinópolis, Minas Gerais, took part in this study. RESULTS: The physical therapists' representations about RSI/WRMSD and patients were collectively elaborated on the basis of the therapists daily practice. A reductionistic thinking style with a mechanistic conceptualization of the human organism was perceived among the interviewees. CONCLUSIONS: It is insufficient to direct efforts towards restoring the normal functioning of the body if the patient's needs are ignored. Physical therapists' scientific and technical knowledge should be reconciled with patients' subjective expression, in order to seek more effective intervention strategies.

Breathing pattern, thoracoabdominal motion and muscular activity during three breathing exercises

The objective of the present study was to evaluate breathing pattern, thoracoabdominal motion and muscular activity during three breathing exercises: diaphragmatic breathing (DB), flow-oriented (Triflo II) incentive spirometry and volume-oriented (Voldyne) incentive spirometry. Seventeen healthy subjects (12 females, 5 males) aged 23 ± 5 years (mean ± SD) were studied. Calibrated respiratory inductive plethysmography was used to measure the following variables during rest (baseline) and breathing exercises: tidal volume (Vt), respiratory frequency (f), rib cage contribution to Vt (RC/Vt), inspiratory duty cycle (Ti/Ttot), and phase angle (PhAng). Sternocleidomastoid muscle activity was assessed by surface electromyography. Statistical analysis was performed by ANOVA and Tukey or Friedman and Wilcoxon tests, with the level of significance set at P < 0.05. Comparisons between baseline and breathing exercise periods showed a significant increase of Vt and PhAng during all exercises, a significant decrease of f during DB and Voldyne, a significant increase of Ti/Ttot during Voldyne, and no significant difference in RC/Vt. Comparisons among exercises revealed higher f and sternocleidomastoid activity during Triflo II (P < 0.05) with respect to DB and Voldyne, without a significant difference in Vt, Ti/Ttot, PhAng, or RC/Vt. Exercises changed the breathing pattern and increased PhAng, a variable of thoracoabdominal asynchrony, compared to baseline. The only difference between DB and Voldyne was a significant increase of Ti/Ttot compared to baseline. Triflo II was associated with higher f values and electromyographic activity of the sternocleidomastoid. In conclusion, DB and Voldyne showed similar results while Triflo II showed disadvantages compared to the other breathing exercises.

Estudos de revisão sistemática: um guia para síntese criteriosa da evidência científica / Systematic review studies: a guide for careful synthesis of the scientific evidence

INTRODUÇÃO: Agregar evidências de pesquisa para guiar a prática clínica é uma das principais razões para se desenvolverem estudos que sintetizam a literatura, mas não é a única. As revisões sistemáticas são desenhadas para ser metódicas, explícitas e passíveis de reprodução. Esse tipo de estudo serve para nortear o desenvolvimento de projetos, indicando novos rumos para futuras investigações e identificando quais métodos de pesquisa foram utilizados em uma área. MÉTODOS: Uma revisão sistemática requer uma pergunta clara, a definição de uma estratégia de busca, o estabelecimento de critérios de inclusão e exclusão dos artigos e, acima de tudo, uma análise criteriosa da qualidade da literatura selecionada. O processo de desenvolvimento desse tipo de estudo de revisão inclui caracterizar cada estudo selecionado, avaliar a qualidade deles, identificar conceitos importantes, comparar as análises estatísticas apresentadas e concluir sobre o que a literatura informa em relação a determinada intervenção, apontando ainda problemas/questões que necessitam de novos estudos. Um trabalho de revisão sistemática segue a estrutura de um artigo original. CONCLUSÃO: Boas revisões sistemáticas são recursos importantes ante o crescimento acelerado da informação científica. Esses estudos ajudam a sintetizar a evidência disponível na literatura sobre uma intervenção, podendo auxiliar profissionais clínicos e pesquisadores no seu cotidiano de trabalho.

INTRODUCTION: Aggregation of research evidence to guide clinical practice is one of the main reasons for conducting studies that provide a synthesis of the literature, but it is not the only reason. Systematic reviews are designed to be methodical, explicit and replicable. Such studies may help to guide project development, by indicating new directions for further investigations and identifying which research methods have been used within a given area. METHODS: Systematic reviews require straightforward questions, search strategy definition, establishment of study inclusion and exclusion criteria and careful analysis of the selected literature. The development process for reviews of this type includes characterization of each selected study, evaluation of their quality, identification of important concepts, comparison of statistical analyses used and conclusions regarding what the literature tells us about a specific intervention. Such reviews also suggest problems/questions that need further investigation. Systematic review studies follow the structure of original articles. CONCLUSION: Good systematic reviews are important resources, in the light of the accelerated growth of scientific information. These studies help in producing syntheses of the evidence available in the literature on specific interventions, and may help clinicians and researchers in their work process.

Use of fibrin glue derived from snake venom in the repair of deep corneal ulcers: experimental study in dogs (Canis familiaris, Linnaeus, 1758)

Fibrin glue has been researched as an alternative method for tissue synthesis and is known for its capability to promote hemostasis at the application site, good approximation of wound edges and fast healing. The current study consisted in the application of fibrin glue derived from snake venom as treatment for experimental corneal ulcers. Twenty-one dogs had their corneas experimentally prepared through lamellar keratectomy (of standardized diameter and depth). Animals were divided into seven groups of three animals each. Six experimental groups were periodically evaluated and collection was carried out on the 1st, 3rd, 7th, 15th, 30th and 60th post-operative days, whereas one control group was evaluated throughout the experiment. Analyses consisted in the clinical evolution and in the histopathological study of all operated on eyes. Results indicated that fibrin glue was efficient in repairing keratectomy wounds in dogs and contributed to an earlier healing phenomenon, avoiding edema formation and keeping corneal clearness. The use of fibrin glue derived from snake venom showed to be easy to apply, feasible with animal models and of low cost, avoiding the lesion progress and allowing fast and appropriate corneal healing.

Inefficacy of the association N-methyl glucamine and topical miltefosine in the treatment of experimental cutaneous leishmaniasis by Leishmania (Leishmania) amazonensis

Pentavalent antimonial (SbV) is the first treatment for cutaneous leishmaniasis (CL). Other drugs present similar side effects and higher cost. Oral miltefosine is effective to treat kala-azar. The aim of the present study was to compare the efficacy of glucamine (SbV) plus topical miltefosine with glucamine in the treatment of CL. Eighty isogenic C57BL/6 mice were inoculated with Leishmania (Leishmania) amazonensis and divided into two groups: one group was treated with SbV associated with miltefosine, and the other group received SbV plus saline solution. Groups were evaluated according to the diameter of the inoculated foot pad, the culture, and the parasite count using the limiting dilution assay. There was not statistical difference. The efficacy of glucamine in CL treatment did not increase when associated with topical miltefosine.(AU)
