Les approches arthroscopiques et l’anatomie normale des articulations antébrachiocarpienne, carpienne moyenne et tarsocrurale n’ont jamais été décrites spécifiquement chez les bovins. Notre étude avait pour buts de définir les abords chirurgicaux et de décrire l’anatomie arthroscopique de ces trois articulations. Deux carpes et deux tarses issus du cadavre frais d’une vache adulte ont été injectés avec un mélange de latex, puis disséqués afin de déterminer les sites arthroscopiques d’intérêt. Par la suite, l’arthroscopie des articulations antébrachiocarpienne et carpienne moyenne (approche dorsale) et de l’articulation tarsocrurale (approches dorsale et plantaire) a été réalisée sur six cadavres frais de vaches adultes ne présentant ni boiterie ni distension articulaire avant leur euthanasie. Les approches dorsolatérale et dorsomédiale des articulations antébrachiocarpienne et carpienne moyenne ont été réalisées de part et d’autre de l’extenseur radial du carpe. Les structures observées étaient le radius distal, les os radial, intermédiaire, ulnaire, II et III fusionnés et IV du carpe, ainsi que des ligaments palmaires. Les approches dorsolatérale et dorsomédiale de l’articulation tarsocrurale ont été réalisées latéralement au long extenseur des doigts et médialement au troisième péronier respectivement. Les approches plantarolatérale et plantaromédiale ont été réalisées latéralement au fléchisseur latéral des doigts et latéralement au fléchisseur médial des doigts respectivement. Les structures observées étaient le tibia distal, les trochlées proximale et plantaire du talus, le processus coracoïde du calcanéus, l’articulation fibulo-calcanéenne et des ligaments articulaires. Quelle que soit l’articulation, l’approche latérale était préférée à l’approche médiale. L’arthroscopie du carpe et du tarse pourra être proposée dans un contexte hospitalier comme outil diagnostique, thérapeutique et pronostique des maladies articulaires bovines.

Detrás de la expedición de derechos, más allá de ese ruido incesante creado por un aparato legal que defiende a la vida y la convierte en un derecho pueden ser halladas relaciones de poder precisas y espacios de regulación y control de los cuerpos y de las poblaciones. Este trabajo pretende observar en la labor de interpretación que lleva a cabo la Corte Constitucional colombiana sobre el derecho a la vida, el establecimiento de una lógica política, que es el biopoder, de acuerdo con los elementos que lo constituyen, tal y como fueron analizados por Michel Foucault. El estudio del biopoder permitirá dar cuenta de tecnologías políticas, técnicas y dispositivos que no solo están presentes en la dimensión biológica de la vida de los colombianos, sino en espacios sociales y éticos que adquieren importancia cuando la vida es cualificada por parte del saber legal. El discurso jurídico aquí juega un papel central pues vincula una vida que era considerada simplemente biológica con nuevos significados y valores como el de la dignidad, y crea, a su vez, formas de sujeción. Temas como el aborto, la eutanasia, la sexualidad, la autonomía de cada quien para decidir sobre su cuerpo, entre otros, dan cuenta de nuevos ámbitos donde se ejerce el biopoder, y que eran poco explorados antes de la Constitución de 1991. Se verá cómo, a partir del análisis de la línea jurisprudencial sobre el derecho a la vida, la Corte Constitucional genera este tipo de espacios y lleva a cabo una intervención sobre una vida que es constantemente cualificada y que es modificada a medida que evoluciona el pensamiento de este tribunal.

El Virus de la Inmunodeficiencia Humana (VIH) y el Síndrome de Inmunodeficiencia Adquirida (SIDA) han tenido a lo largo de los años un comportamiento epidemiológico que muestra la tendencia al aumento, de tal forma que ha llegado a considerarse como un problema de salud pública a nivel mundial. Sin embargo los tratamientos antiretrovirales han permitido que las personas con esta infección tengan una tasa de supervivencia mayor; pero ligado a esto, se han presentado efectos secundarios tales como problemas con la memoria y el funcionamiento cognitivo de estas personas. Además se ha encontrado que las personas con VIH/SIDA tienen algunas alteraciones en su área afectiva y generalmente ven afectada su calidad de vida. Este es un estudio exploratorio descriptivo que tuvo por objeto describir la ansiedad, depresión y percepción de calidad de vida en 35 pacientes con VIH/SIDA con deterioro cognitivo leve, seleccionados por conveniencia. Se aplicaron tres cuestionarios, el BDI-II para evaluar la sintomatología depresiva; el BAI para evaluar la sintomatología ansiosa y el MOS-SF30 para evaluar la calidad de vida. Además, se realizó una entrevista semiestructurada para profundizar en la evaluación de estas tres variables. Dentro de los resultados se evidenció que todos los paciente presentan algún nivel de ansiedad y de depresión, evalúan su calidad de vida en un punto medio; ni óptima ni baja. Se discuten estos y otros resultados.

El suicidio asistido como una posible opción al final de la vida, es una idea que hasta ahora está siendo considerada, ya que existen argumentaciones a favor y en contra que han generado controvertidos debates a su alrededor. Algunos de los argumentos en contra están basados en los principios de las instituciones religiosas de orden cristiano, las cuales defienden el valor sagrado de la vida de las personas y la aceptación del sufrimiento como un acto de amor profundo y sumisión a los mandatos de Dios, el creador. Mientras del lado contrario, se encuentran quienes defienden el procedimiento, impulsando la autonomía y la autodeterminación que cada persona tiene sobre su vida. La revisión de la literatura realizada no sólo permite ampliar los argumentos de estas dos posiciones, sino que también permite conocer la historia del suicidio asistido, la posición que este procedimiento tiene en diferentes países del mundo, incluyendo a Colombia, y finalmente se presentan las contribuciones de la psicología entorno al procedimiento en discusión.

Com o aumento da esperança média de vida dos gatos a percentagem de animais seniores/geriátricos tem vindo a aumentar. Este fator vem trazer a necessidade de uma adaptação dos cuidados médicos associados à fase de vida do animal, com o consequente conhecimento de quais as principais doenças e principais causas de morte nos gatos desta faixa etária. Os objetivos deste estudo passam por tentar determinar as causas de morte mais frequentes em cem gatos com mais de nove anos, associando-as com características intrínsecas e com a prática de eutanásia. Concluiu-se que a doença mais associada à causa de morte nos animais estudados foi a doença renal crónica, seguindo-se os tumores e as doenças infeciosas. A média de idade à morte foi de 12,69 para a totalidade dos animais. Género, estado fértil e raça do animal em estudo foram independentes de todas as doenças. A média de peso foi superior para gatos machos, Europeus Comum e com diabetes mellitus e inferior para gatos com doença renal crónica. 56% dos gatos foram eutanasiados.

Objectives The purpose of this study was to evaluate the effectiveness of the acellular dermal matrix (ADM) as a membrane for guided bone regeneration (GBR), in comparison with a bioabsorbable membrane. Material and methods In seven dogs, the mandibular pre-molars were extracted. After 8 weeks, one bone defect was surgically created bilaterally and the GBR was performed. Each side was randomly assigned to the control group (CG: bioabsorbable membrane made of glycolide and lactide copolymer) or the test group (TG: ADM as a membrane). Immediately following GBR, standardized digital X-ray radiographs were taken, and were repeated at 8 and 16 weeks post-operatively. Before the GBR and euthanasia, clinical measurements of the width and thickness of the keratinized tissue (WKT and TKT, respectively) were performed. One animal was excluded from the study due to complications in the TG during wound healing; therefore, six dogs remained in the sample. The dogs were sacrificed 16 weeks following GBR, and a histomorphometric analysis was performed. Area measurements of new tissue and new bone, and linear measurements of bone height were performed. Results Post-operative healing of the CG was uneventful. In the TG membrane was exposed in two animals, and one of them was excluded from the sample. There were no statistically significant differences between the groups for any histomorphometric measurement. Clinically, both groups showed an increase in the TKT and a reduction in the WKT. Radiographically, an image suggestive of new bone formation could be observed in both groups at 8 and 16 weeks following GBR. Conclusion ADM acted as a barrier in GBR, with clinical, radiographic and histomorphometric results similar to those obtained with the bioabsorbable membrane.

In this study, we investigated the effect of the supplementation with the dipeptide L-alanyl-L-glutamine (DIP) and a solution containing L-glutamine and L-alanine on plasma levels markers of muscle damage and levels of pro-inflammatory cytokines and glutamine metabolism in rats submitted to prolonged exercise. Rats were submitted to sessions of swim training for 6 weeks. Twenty-one days prior to euthanasia, the animals were supplemented with DIP (n = 8) (1.5 g.kg(-1)), a solution of free L-glutamine (1 g.kg(-1)) and free L-alanine (0.61 g.kg(-1)) (G&A, n = 8) or water (control (CON), n = 8). Animals were killed at rest before (R), after prolonged exercise (PE-2 h of exercise). Plasma concentrations of glutamine, glutamate, tumour necrosis factor-alpha (TNF-alpha), prostaglandin E2 (PGE2) and activity of creatine kinase (CK), lactate dehydrogenase (LDH) and muscle concentrations Of glutamine and glutamate were measured. The concentrations of plasma TNF-alpha, PGE2 and the activity of CK were lower in the G&A-R and DIP-R groups, compared to the CON-R. Glutamine in plasma (p < 0.04) and soleus muscle (p < 0.001) was higher in the DIP-R and G&A-R groups relative to the CON-R group. G&A-PE and DIP-PE groups exhibited lower concentrations of plasma PGE2 (p < 0.05) and TNF-alpha (p < 0.05), and higher concert I rations of glutamine and glutamate in soleus (p < 0.001) and gastrocnemius muscles (p < 0.05) relative to the CON-PE group. We concluded that supplementation with free L-glutamine and the dipeptide LL-alanyl-LL-glutamine represents an effective source of glutamine, which may attenuate inflammation biomarkers after periods of training and plasma levels of CK and the inflammatory response induced by prolonged exercise.

Neonatal anoxia is a worldwide clinical problem that has serious and lasting consequences. The diversity of models does not allow complete reproducibility, so a standardized model is needed. In this study, we developed a rat model of neonatal anoxia that utilizes a semi-hermetic system suitable for oxygen deprivation. The validity of this model was confirmed using pulse oximetry, arterial gasometry, observation of skin color and behavior and analysis of Fos immunoreactivity in brain regions that function in respiratory control. For these experiments, 87 male albino neonate rats (Rattus norvegicus, lineage Wistar) aged approximate 30 postnatal hours were divided into anoxia and control groups. The pups were kept in an euthanasia polycarbonate chamber at 36 +/- 1 degrees C, with continuous 100% nitrogen gas flow at 3 L/min and 101.7 kPa for 25 min. The peripheral arterial oxygen saturation of the anoxia group decreased 75% from its initial value. Decreased pH and partial pressure of oxygen and increased partial pressure of carbon dioxide were observed in this group, indicating metabolic acidosis, hypoxia and hypercapnia. respectively. Analysis of neuronal activation showed Fos immunoreactivity in the solitary tract nucleus, the lateral reticular nucleus and the area postrema, confirming that those conditions activated areas related to respiratory control in the nervous system. Therefore, the proposed model of neonatal anoxia allows standardization and precise control of the anoxic condition, which should be of great value in indentifying both the mechanisms underlying neonatal anoxia and novel therapeutic strategies to combat or prevent this widespread public health problem.

O espessamento intimal e a reestenose que ocorrem após os procedimentos de angioplastia transluminal percutânea e/ou o implante de stents representam uma causa freqüente de falência destes procedimentos. O principal achado patológico responsável pela reestenose parece ser a hiperplasia intimal, já que o dispositivo intravascular é resistente ao remodelamento arterial geométrico. O propósito deste estudo é avaliar, através da morfometria digital, o espessamento intimal presente nas regiões da parede arterial imediatamente proximal e distal ao implante de um stent metálico em configuração em “Z “ não recoberto ou recoberto com PTFE. Vinte e cinco suínos de raça mista, com seis a dez semanas de idade, pesando em média 20 kg foram divididos em três grupos. No grupo I, cinco animais foram submetidos à exposição cirúrgica retroperitoneal da aorta abdominal, aortotomia e manipulação com uma bainha introdutora de 12 F. O grupo II incluiu dez animais que foram submetidos ao implante de um stent metálico auto-expansível não recoberto. No grupo III, incluindo também dez animais, foram implantados stents recobertos com PTFE. Após quatro semanas, todos os animais foram sacrificados e o segmento aorto-ilíaco foi removido. Quatro animais foram excluídos do estudo por trombose da aorta (um animal do grupo II e três animais do grupo III). Para a análise morfométrica foram utilizados os testes não paramétricos de Wilcoxon e de Kruskal-Wallis, para as comparações, respectivamente, no mesmo grupo e entre os grupos. Foi adotado o nível de significância de 5% ( p< 0,05). Quando os espécimes da parede arterial, imediatamente proximal e distal aos stents foram comparados, nenhuma diferença estatisticamente significativa foi encontrada entre as áreas luminal, intimal, média ou índice intimal em cada grupo. Na comparação entre os grupos, as áreas intimal, média e o índice intimal não demonstraram variação estatisticamente significativa. Foram identificadas diferenças entre os grupos quanto às áreas luminais proximais (p = 0,036) e distais (p=0,044). Pelo teste de comparações múltiplas para Kruskal-Wallis (Teste de Dunn) identificou-se diferença significativa entre os grupos I e II. Entretanto, quando estas variáveis foram controladas pelo fator peso (relação área luminal/peso) a diferença não foi mais observada. Concluímos que, após quatro semanas, stents recobertos com PTFE induzem um espessamento intimal justa-stent similar ao observado com stents não recobertos ou com a simples manipulação arterial com uma bainha introdutora. Neste modelo experimental suíno, de curto seguimento, o revestimento com PTFE não foi responsável por adicional espessamento intimal.

INTRODUÇÃO: O adenocarcinoma de pâncreas apresenta um mau prognóstico. A utilização de modelos experimentais é necessária para a compreensão do comportamento biológico tumoral, principalmente das lesões precoces (neoplasias intra-epiteliais pancreáticas - NIPan) e para o desenvolvimento de opções terapêuticas. OBJETIVO: Avaliar a carcinogênese pancreática induzida por 7,12-dimetilbenzantraceno (DMBA), em camundongos, aplicando a classificação das neoplasias intra-epiteliais pancreáticas. MÉTODOS: 90 camundongos machos, mus musculus, da cepa CF1, foram submetidos à laparotomia mediana e 1 mg de DMBA foi implantado na porção cefálica do pâncreas. Os animais foram divididos em dois grupos, com eutanásia em 30 e 60 dias. Em seguida, o pâncreas foi retirado, fixado em formalina e foram confeccionadas lâminas coradas com hematoxilina eosina. Os cortes histológicos foram avaliados por dois patologistas de acordo com os seguintes critérios: pâncreas normal, hiperplasia reacional, NIPan 1A, NIPan 1B, NIPan 2, NIPan 3 e carcinoma. As alterações inflamatórias também foram analisadas. RESULTADOS: A avaliação patológica evidenciou, no grupo de 30 dias: 4 (16,7%) animais com hiperplasia reativa, 16 (66,6%) com NIPan e 4 (16,7%) com adenocarcinoma. No grupo de 60 dias: 10 (27,1%) animais com hiperplasia reativa, 13 (35,1%) com NIPan e 14 (37,8%) com adenocarcinoma. A diferença entre os grupos apresentou significância estatistística (P < 0,05 – teste exato de Fisher). A prevalência de alterações inflamatórias em 30 dias foi: pancreatite aguda (n=11), pancreatite crônica (n=5) e inflamação dependente da bolsa (n=8). No grupo de 60 dias 11 espécimes apresentavam pancreatite aguda e 26 pancreatite crônica. CONCLUSÕES: O modelo experimental com DMBA em camundongos, induz neoplasia intra-epitelial pancreática e adenocarcinoma ductal histologicamente semelhantes ao carcinoma pancreático em humanos. Este modelo pode ser utilizado na investigação da carcinogênese com enfoque na progressão molecular das lesões precursoras até o adenocarcinoma.

Esta pesquisa experimental de campo pretende ser o primeiro de uma série de trabalhos, visando a investigação do tema eutanásia em seu envolvimento no campo, da psicologia social. Seu objetivo foi o estudo da influência nas crenças religiosas na atitude em relação à eutanásia. Foram testados seis grupos religiosos: espírita, messiânico, batista, umbandista, católico e candornblecista. Cada um deles incluiu 50 sujeitos. O instrumento usado foi a "Escala de Atitude sobre a Eutanásia", construída pela autora desta pesquisa e composta de 26 itens. Esta escala apresentou índices altamente satisfatórios de validade e fidedignidade. Aborda, além do aspecto geral do problema, os enfoques jurídico, médico e moral-religioso. Foi examinada a relação entre escolaridade, sexo, idade e atitude sobre eutanásia. Os resultados obtidos evidenciaram a existência de relação altamente significativa entre crenças religiosas e atitude sobre eutanásia, confirmando a hipótese básica do trabalho. As implicações destes resultados são discutidas e o próximo trabalho da série, já está sendo planejado, será o exame da atitude de médicos e advogados em relação à eutanásia, como eles a definem e caracterizam.

To evaluate the effect of sildenafil, administered prior to renal ischemia/reperfusion (I/R), by scintigraphy and histopathological evaluation in rats. Methods: Twenty-four rats were divided randomly into two groups. They received 0.1 ml of 99mTechnetium-etilenodicisteine intravenous, and a baseline (initial) renal scintigraphy was performed. The rats underwent 60 minutes of ischemia by left renal artery clamping. The right kidney was not manipulated. The sildenafil group (n=12) received orally 1 mg/kg of sildenafil suspension 60 minutes before ischemia. Treatment with saline 0.9% in the control group (n=12). Half of the rats was assessed after 24 hours and half after seven days I/R, with new renal scintigraphy to study differential function. After euthanasia, kidneys were removed and subjected to histopathological examination. For statistical evaluation, Student t and Mann-Whitney tests were used. Results: In the control group rats, the left kidneys had significant functional deficit, seven days after I/R, whose scintigraphic pattern was consistent with acute tubular necrosis, compared with the initial scintigraphy (p<0.05). Sildenafil treatment resulted in better differential function of the left kidneys 24h after reperfusion, compared with controls. Histopathologically, the left kidney of control rats (24 hours after I/R) showed a higher degree of cellular necrosis when compared with the sildenafil treated rats (p<0.05). Conclusion: Sildenafil had a protective effect in rat kidneys subjected to normothermic I/R, demonstrated by scintigraphy and histomorphometry

Canine Visceral Leishmania (CVL) is an important zoonotic disease that has a world wide distribution and has a large impact on public health on the American Continent, especially in Brazil, where the nature of endemic diseases in humans affects a large part of the nation. The influence of the prevalence of CVL in the increased rate of human cases in endemic areas and in the unleashing of epidemic outbreaks shows the need for a more profound understanding, that would generate significant advances in the current measures used to control the reservoirs of sickness that are practiced by the Programa Nacional de Vigilância e Controle da Leishmaniose Visceral. The present work describes and compares the clinical-laboratorial and histopathological findings of twenty-three dogs that were naturally infected by Leishmania chagasi, from endemic areas in metropolitan Natal, Rio Grande do Norte, Brazil. These animals, that were selected and given physical and serological exams (IFI and ELISA rK-39), were classified according to the degree of clinical severity and had blood samples drawn (whole blood and serum) for a complete hemogram and a coagulogram to be done as well as biochemical tests for kidney and liver function. The confirmation of infection by L. chagasi was done after the euthanasia of the animals, through the direct demonstration of the parasite in the impression of the spleen and liver crowned with GIEMSA and through a cultivation by means of NNN/Schneider. According to the clinical evaluation, the animals were classified as asymptomatic (7), oligosymptomatic (7) and polysymptomatic (9). Among the animals that were chosen to be autopsied, there were 2 asymptomatic, 3 oligosymptomatic and 3 polysymptomatic, for the purpose of studying their histopathology, having collected fragments of the spleen, liver, kidneys and skin and were fixed in 10% tamponed formol. The comparison between the average parameters of the clinical-laboratory tested animals in the groups was done through the Student t test (a<0.05). The main clinical signals observed were lymphadenomegaly, alopecy, dermatitis, exfoliation, cutaneous ulcers, onicogriphosis and emaciation. The main clinical-laboratorial alterations established, mainly in the polysymptomatic group, were anemia, hyperproteinemia, hyperglobulinemia, alterations in the albumin/globulin ratio and increased ALT activity. Renal alterations were not verified (urea and creatinine levels were normal). Thrombocytopenia was observed in three clinical groups. However, the other indicators of coagulation function (TAP and TTPA) did not have abnormal variations. There were inflammatory infiltrations and leishmania amastigotes in the skin of polysymptomatic dogs, however, they were not found in the skin of asymptomatic animals. Hypertrophy and hyperplasia of the phagocyte mononuclear system, leishmania amastigote parasites were found in the macrophages, extramedullary hematopoiesis and degenerative alterations were detected in the spleen and liver of 8 of the animals submitted to histopathological exams. In accord with these results, it was demonstrated that the expected alterations in the hematological and biochemical parameters in function of their viscerotropic nature of CVL are mainly observed in the more advanced stages of the disease. The absence of inflammatory infiltration and parasite load in the skin suggest that infected animals without symptoms may have an importance irrelevant to the infectiousness of the vector

Ulcerative colitis comprising an inflammatory bowel disease, whose most severe consequence is the development of intestinal neoplasia. The drugs currently used to treat the disease trigger a variety of serious adverse effects and are not effective in many cases. Recent studies demonstrated the effectiveness of natural products for the treatment of inflammatory processes. Seaweed extracts and their purified products have shown protective effects in models of inflammation and the association of traditional therapies with probiotics has significantly improved the clinical symptoms of ulcerative colitis. Therefore, the aims of this study include evaluating the potential effects of the use of probiotic strain Enterococcus faecium 32 (Ef32), the methanolic extract of the green seaweed Caulerpa mexicana (M.E.) and their concomitant administration in a murine model of colitis induced by dextran sodium sulfate (DSS). Accordingly, C57BL /6 mice were pretreated orally with Ef32 (109 CFU/ml) for seven days. In the seven days following, the colitis was induced by administration of 3% DSS (w/v) diluted in the animals drinking water. During this period, animals were treated daily with Ef32 and the M.E. (2.0 mg/kg) every other day by intravenous route. The development of colitis was monitored by the disease activity index (DAI), which takes into account the loss of body weight, consistency and presence of blood in stools. After euthanasia, the colon was removed, its length measured and tissue samples were destined for histological analysis and culture for cytokine quantification. The levels of cytokines in the culture supernatant of the colon were measured by ELISA. The treatments with the probiotic Ef32 or the M.E. alone or the combination of these two substances provoked significant improvement as to weight loss and DAI, and prevented the shortening of the colon in response to DSS. The isolated treatments triggered a slight improvement in intestinal mucosal tissue damage. However, their combination was able to completely repair the injury triggered by DSS. The association was also able to reduce the levels of all the cytokines analyzed (IFN-γ, IL-4, IL-6, IL-12, IL-17A and TNF-α). On the other hand, the treatment with Ef32 did not interfere with the levels of TNF-α, whereas treatment with M.E. did not alter the levels of IL-6. Moreover, the treatment with Ef32 not interferes in TNF-α levels, whereas treatment with M.E. did not alter the levels of IL-6. Therefore, the potential probiotic Ef32 and M.E. and especially when these samples were associated proved promising alternatives in the treatment of ulcerative colitis as demonstrated in an experimental model because of its beneficial effects on morphological and clinical parameters, and by reducing the production of proinflammatory cytokines of Th1, Th2 and Th17
