  • Vascularization of chickens adrenal glands in NPK lineage (Gallus
           gallus domesticus)

    • Abstract: Com o objetivo de contribuir com o conhecimento referente aos arranjos vasculares viscerais, que freqüentemente mostram suficientes variações para diferenciação entre famílias e ordens, utilizamos 34 galinhas da linhagem NPK, com idade aproximada de 10 semanas, eutanasiadas com dose de gás anestésico, tendo marcado seus contingentes arteriais com solução aquosa de Neoprene Látex ¨450¨ a 50 %, corada com corante específico e fixadas em solução aquosa de formol a 10 %, para estudar a vascularização das glândulas adrenais. Assim, os resultados indicam que as glândulas adrenais são órgãos pares, dispostos um em cada antímero, lateralmente à aorta descendente, caudalmente aos pulmões e médio-cranialmente aos rins. Nos dois antímeros, as glândulas adrenais receberam vasos oriundos das artérias adrenais homólogas provenientes da artéria renal cranial e da aorta descendente (ramos diretos). Independentemente da origem, o número de ramos destinados às glândulas adrenais variou de acordo com o antímero, sendo de 1 a 4 para o antímero esquerdo, e de 1 e 3 para o direito. Quanto maior o número de artérias totais e ramos emitidos pelas artérias adrenais contralaterais destinados a um antímero, maior será o número de ramos destinados pelas mesmas ao antímero oposto.Aiming at knowing the visceral vascular arrangements which frequently show huge variation to be differentiated in families and orders, we used 34 NPK chickens, aged at approximately 10 weeks, euthanized with a dose of anaesthetic gas, with arterial contingents marked with an aqueous 50 % Neoprene Latex ¨450¨ solution, colored with a specific coloring agent and fixed in an aqueous 10% formaldehyde solution, to study adrenal gland vascularization. The results indicated that the adrenal glands are paired organs, positioned in each antimer, laterally to the descending aorta, caudally to the lungs and medio-cranially to the kidneys. In the two antimers, the adrenal glands receive vessels originating from the homologous adrenal arteries that come from the cranial renal artery and from the descending aorta (right branches). Regardless of their origin, the number of branches destined to the adrenal glands varied according to the antimer, totaling 1 to 4 for the left antimer, and 1 to 3 for the right one. The higher the number of total arteries and branches emitted by the contralateral adrenal arteries destined to an antimer, the higher the number of branches they destine to the opposite antimer.
  • Clinic-radiographic study of congenital atlantoaxial subluxation in

    • Abstract: Neste estudo foram analisadas ficha clínica e radiografias simples de cães com diagnóstico de subluxação atlantoaxial congênita, obtidos junto ao Serviço de Radiologia do Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo, no período de janeiro de 1990 a dezembro de 1999. Durante este período, foram identificados sete cães com alterações do processo odontóide do áxis (agenesia ou hipoplasia), levando à instabilidade da articulação atlantoaxial e conseqüente compressão medular. Todos os animais, com idade igual ou inferior a um ano, apresentavam sinais neurológicos. O diagnóstico definitivo foi firmado mediante as alterações observadas em exame radiográfico simples.This retrospective study reviews the clinical signs and plain radiographic findings in dogs with congenital atlantoaxial subluxation. The data were obtained from the Radiology Department of the Veterinary Teaching Hospital, School Veterinary Medicine of University of São Paulo during period from january 1990 to december 1999. In this 10-year period, seven dogs were reported with malformation of dens axis (agenesis or hypoplasia), what caused articular instability and spinal cord compression. All the animals were one year old or younger and all had neurologic signs. Diagnosis was made with plain cervical radiographs.
  • Techinical implications of the vaccination in the immune response against
           the foot-and-mouth disease virus

    • Abstract: Na bovinocultura brasileira, a vacinação contra o vírus da Febre Aftosa (FA) é fundamental para a fase inicial de erradicação da enfermidade. Mesmo a qualidade da vacina tendo controle rígido feito pelos órgãos oficiais, restam variáveis técnicas ainda não monitoradas como manipulação, transporte e conservação pelo consumidor, dose, local e forma de aplicação que interferem na resposta imune, preocupações essas, que direcionam o presente estudo. Assim, pela pesquisa de anticorpos neutralizantes do vírus da FA em placas de microtitulação com cultivo de células BHK-21, foram determinados os títulos, calculados em logaritmo decimal (SN), em soros sanguíneos de bovinos vacinados conforme o protocolo apresentado. No primeiro grupo com 25 animais, a média de SN foi igual a 2,37 e 2,19, respectivamente, 30 e 180 dias após a vacinação, cuja vacina foi manejada por especialista com todos os cuidados técnicos recomendados. Outro grupo com 140 bovinos, distribuídos em 5 fazendas distintas, apresentou média de SN igual a 1,66 e 1,5l depois de 30 e 180 dias após a vacinação, cuja vacina foi manejada sem acompanhamento técnico e por indivíduos não especializados. Finalmente um terceiro grupo com 10 animais, que ficaram sem vacinação, apresentou média de SN igual a 0,82 e 0,81, também 30 e 180 dias após a aplicação do placebo. Assim, só os cuidados com a qualidade da vacina são insuficientes para proporcionar títulos satisfatórios que determinam proteção dos rebanhos contra o vírus da FA, uma vez que a literatura pertinente considera rebanhos com 1,52 de média do SN como tendo 50% dos animais protegidos, e com 1,70 como tendo mais de 70% de proteção, no período de até 7 meses.In Brazilian cattle-breeding, the vaccination against the foot-and-mouth disease virus is essential during the early stages of disease erradication programmes. In spite of the official control on the vaccine quality, thecnical variables, as manipulation, transportation and conservation by the consumer, dosage, place and manner of inoculation that interfere with the immune response, remain unmonitered and are the concerns that guide this study.Titers of neutralizing antibodies to the foot-and-mouth disease virus were established in microtitration plates with BHK-21 cell culture, calculated in decimal logarithm, in sera from cattle vaccinated according to the protocol presented. Among 25 animals of the first group, the mean antibody titers were 2.37 and 2.19, respectively, 30 and 180 days after the inocculation of a vaccine manipulated by specialized people, adopting all the recomended technical cares. Another group, with 140 cattle from 5 different farms, showed mean antibody titers of 1.66 and 1.51, respectively, 30 and 180 days after the inoculation of a vaccine manipulated without technical monitoring and by unspecialized people. Finally, a third group with 10 unvaccinated animals had mean antibody titers of 0.82 and 0.81 respectively, 30 and 180 days after the inoculation of a placebo. So, only the control of the vaccine quality was not enough to give to the herds satisfactory protection against the foot-and-mouth disease virus, since the literature considers that, in herds with a mean titer of 1.52, 50% of the animals are protected, and 70% of the animals in herds with mean titer of 1.70 are protected for a period of 7 months.
  • Anti-human influenza protector antibody detected in horses as a
           zoonotic viruses

    • Abstract: This study aimed to investigate the incidence of the influenza virus, and its interspecies transmission cycle among horses. A comparative serological survey was performed using horse sera following challenge with both specific (equine) and non-specific (human) influenza virus strains. Bleedings of the 22 horses were performed during the years 1999 and 2000. Following treatment with kaolin (20%), added in rooster erythrocytes suspension (50%), for removal of non-specific antibodies, sera were titered against both Human and Equine Influenza virus, by the Hemagglutination Inhibition Assay(HI), recommended by WHO. The HI results of horse serological responses demonstrate cross reaction between both the specific strain, A/Eq1 (H7N7) ( 62.75%) and A/Eq2 (H3N8) (60.65%), and the non- specific strains, type A (H1N1) (79.5%) and A (H3N2) (94.45%) and type B (77.75%). It was noteworthy the high percentage of protection responses in equine sera aginst the non-specific strains, as compared with the specific strains. This finding suggests direct interspecies transmission of influenza virus as zoonotic viruses, particulary for the type B strain which is considered restricted to humans. It was the first report, in Brazil. Further studies are required to achieve a complete understanding of the incidence of influenza in our environment.O objetivo deste estudo foi investigar em cavalos, a incidência do vírus influenza e seu ciclo de transmissão interespécies. Portanto, levantamento sorológico foi realizado em soro de cavalos, confrontados com ambas cepas, as específicas (eqüino) e não específicas (humana) deste vírus. Sangrias de cavalos realizadas nos anos de 1999 e de 2000, forneceram soros que, após tratamento com Caolim (20%) e hemácias de galo(50%) para remoção dos anticorpos inespecíficos, foram titulados contra ambas referidas cepas, através do teste de Inibição da Hemaglutinação (recomendado pela OMS). Os resultados, demonstraram que as respostas sorológicas dos cavalos apresentaram reação cruzada entre as cepas específicas e as não específicas. As porcentagens de títulos IH obtidos foram de 62,75% e de 60,65% para as cepas específicas A/Eq1 (H7N7) e A/Eq2 (H3N8), respectivamente. E às cepas não específicas essas porcentagens foram de: 79,05% para A (H1N1), de 94,45% para A (H3N2) e de 77,75% ao tipo B. O mais relevante nestes dados comparativos com vírus influenza, foi a alta porcentagem de resposta protetora à cepa não específica comparada àquela específica, detectada nos soros eqüinos. Considerando o fato de que o tipo B, deste vírus, ser restrito à espécie humana, portanto a resposta de proteção nos cavalos sugere uma direta transmissão interspécies, como em viroses zoonóticas. Os autores relatam pela primeira vez este tipo de evento no Brasil.
  • Evaluation of mineral bone density in thoroughbred horses under an initial
           trainning programme

    • Abstract: A Densitometria Óptica Radiográfica (DOR) é um método de análise para a quantificação da matéria mineral óssea em equivalência à milímetros de alumínio (mmAl). O estudo da densidade óssea dos animais foi realizado através de radiografias simples do osso acessório do carpo ao lado de uma escala de alumínio, após a calcificação da cartilagem de crescimento da epífise distal do osso rádio. Foram utilizados 100 animais divididos em dois grupos, sendo um de machos (50 animais) e outro de fêmeas (50 animais), em início de atividade atlética. As imagens radiográficas foram digitalizadas e analisadas por um programa específico para a comparação de tonalidades (ImageLab, Softium Sistemas de Informática), obtendo-se assim os valores finais de densidade óssea em mmAl. Estes resultados foram analisados estatisticamente (Instat) a fim de se determinar a faixa de normalidade da densidade óssea pelo método da DOR para a população em estudo.The Radiographic Optical Densitometry (ROD) is an analysis method for bone mineral content evaluation in equivalence to the aluminiun milimeters (mmAI). Bone densitometry was performed by a carpal acessory bone simple latero-medial radiograph conjugated with an aluminium stepwedge after complete calcification of growth plate of radial distal epifisis. Two groups (divided by sexual category male/female) of 50 animals each were evaluated and all these 100 animals were under an initial trainning program during the experiment. Radiographs were digitalized and analyzed by a specific software (Imagelab, Softium) responsible for bone densitometry final determination expressed in mmAI. Statistical analysis (Instat) was performed on results for determination of normal curve of bone density by ROD method.
  • Polycystic ovarian syndrome: temporal characterization of the induction
           and reversion process in an experimental model

    • Abstract: Numerous experimental models have been developed for the study of the polycystic ovarian syndrome in the rat. In the present study, the syndrome was induced by exposure to constant light. The process was evaluated during its induction and also during its reversion. The estral cycle was analyzed through the vaginal cytology; reproductive parameters were evaluated by mating, as well as the ovarian morphology. All the animals developed the syndrome after 13 weeks of permanent light. The histologic characteristics of the ovaries, at week 15, were similar to those observed in the polycystic ovarian syndrome in human and other species. After regression of the syndrome, there was not difference in any of the evaluated reproductive parameters, when compared with the control group.Numerosos modelos experimentais têm sido desenvolvimos para o estudo da síndrome do ovário policístico em ratos. No presente estudo, a síndrome foi inducida por exposição à luz constante. O processo foi avaliado durante sua indução e inclusive durante sua reversão. O ciclo estral foi analisado através de citologia vaginal; parámetros reprodutivos foram avaliados por acasalamento, bem como a morfologia ovariana. Todos animais desenvolveram a síndrome depois de 13 semanas de luz permanente. As características histológicas dos ovários, na semana 15, foram similares àquelas observadas na síndrome do ovário policístico em humanos e outras espécies. Após a regressão da síndrome, não houve diferenta em nenhum dos parámetros reprodutivos avaliados, quando comparados com o grupo controle.
  • Occurence of the bovine viral diarrhoea in the south region of the state
           of Minas Gerais and northeast region of the state of São Paulo

    • Abstract: Amostras de soro sangüíneo de 376 vacas lactantes foram analisadas para pesquisa de anticorpos contra o vírus da diarréia viral bovina por meio do teste de ELISA indireto. O estudo foi realizado em 10 propriedades leiteiras localizadas nas regiões sul do Estado de Minas Gerais e nordeste do Estado de São Paulo, entre os meses de março e junho de 2000. Em todas as propriedades foram encontrados animais reagentes e a ocorrência nas duas regiões foi proporcionalmente similar, sendo que na região sul do Estado de Minas Gerais a ocorrência foi de 57,56% e na região nordeste do Estado de São Paulo foi de 56,49%. Foram também analisadas as características das propriedades e dos rebanhos, sendo que as maiores ocorrências foram encontradas nos rebanhos mais simples e nas propriedades menos tecnificadas.Samples of serum of 376 lactating cows were analyzed for research of antibodies against the virus of the bovine viral diarrhoea virus, through the test of indirect ELISA. The study was accomplished in 10 dairy herds located in the South region of the State of Minas Gerais and Northeast region of the State of São Paulo, between the months of march and june of 2000. In all the herds were found reactor animals and the occurrence in the two regions was proportionally similar. In the South region of the State of Minas Gerais the occurrence was 57,56% and in the Northeast region of the State of São Paulo was 56,49%. Also were analyzed the characteristics of the properties and of the flocks and the largest occurrences were found in the simplest flocks and in properties less technicality.
  • Sporothrix schenckii isolation from blood clot of naturally
           infected cats

    • Abstract: O diagnóstico de esporotricose disseminada costuma ser obtido através da necrópsia e o isolamento de Sporothrix schenckii do sangue é raro. Fungemia foi demonstrada in vivo através do isolamento do S. schenckii do sangue periférico de 13 (n=38; 34,2%) gatos com esporotricose naturalmente adquirida. A coinfecção com FIV e com FeLV encontradas, respectivamente, em 6 (n=34; 17,6%) casos e 1 (n=34; 2,9%), aparentemente não alterou a freqüência do isolamento de S. schenckii do sangue periférico. Comparando estes resultados aos dos hemocultivos realizados simultaneamente houve concordância de 84,2%. Assim, propomos o cultivo do coágulo como um método alternativo prático, eficiente e econômico para o diagnóstico de esporotricose disseminada em gatos in vivo.The diagnosis of disseminated sporotrichosis is usually obtained by necropsy and the isolation of Sporothrix schenckii from blood is rare. Fungemia was shown in vivo through the isolation of S. schenckii from peripheral blood of 13 (n=38, 34.2%) cats with naturally acquired sporotrichosis. The coinfection with FIV and with FeLV found, respectively, in 6 (n=34, 17.6%) cases and 1 (n=34, 2.9%), apparently did not alter the frequency of the isolation of S. schenckii from peripheral blood. There was agreement of 84.2% comparing these results to the blood culture results simultaneously achieved. In this way, we propose the clot culture as a practical alternative method, efficient and cheap for the diagnosis of disseminated sporotrichosis in cats in vivo.

    • Abstract: Vinte aditivos* foram utilizados na ensilagem de capim-elefante (80 dias de crescimento), em silos de laboratório: sem aditivos (T1); 0,5% de uréia (T2); 10% de fibra de algodão (T3); 10% de feno de Capim Elefante (T4); 10% de feno de Guandu (T5); emurchecimento por 6 horas (T6); 2% de resíduo de varredura de usina de açúcar (T7); 2% de fubá de milho (T8); 4% de fubá de milho (T9); 6% de fubá de milho (T10); 2% de fubá de milho e 0,5% de uréia (T11); 4% de fubá de milho e 0,5% de uréia (T12); 6% de fubá de milho e 0,5% de uréia (T13); 1% de melaço em pó (T14); 2% de melaço em pó (T15); 3% de melaço em pó (T16); 1% de melaço em pó e 0,5% de uréia (T17); 2% de melaço em pó e 0,5% de uréia (T18); 3% de melaço em pó e 0,5% de uréia (T19); inoculante bacteriano denominado Biosilo (T20). O pH foi maior nos tratamentos T1 (5,36) e T5 (5,33), sendo que nos demais este índice variou de 4,29 a 3,89, sendo estatisticamente semelhantes entre si, podendo ser considerados como dentro da faixa ideal. Os maiores teores de nitrogênio amoniacal foram obtidos nos tratamentos compostos de uréia e em T3. Em comparação ao uso isolado da uréia, a inclusão de 3% de melaço junto a este reduziu a produção de nitrogênio amoniacal e o valor obtido foi semelhante aos demais tratamentos. De maneira geral, as silagens se mostraram predominantemente láticas e a concentração de ácido lático foi semelhante entre os diversos tratamentos. T2 e T3 apresentaram maior produção de ácido butírico e T2 e T9 maiores teores de ácido acético. Os coeficientes de DIVMS variaram de 26,36 a 51,31% e as perdas de MS foram superiores em T2 (11,08%), T3 (10,50%) e T4 (9,80%) e semelhante nos demais.Twenty aditives were been used on ensiling Elephantgrass (80 days growing period): without additives (T1); 0.5% urea (T2); 10% cotton fiber (T3); 10% Elephantgrass hay (T4); 10% Guandu hay (T5); drying for 6 hours (T6); 2% suggar wastes (T7); 2% corn meal (T8); 4% corn meal (T9); 6% corn meal (T10); 2% corn meal and 0.5% urea (T11); 4% corn meal and 0.5% urea (T12); 6% corn meal and 0.5% urea (T13); 1% dried molasses (T14); 2% dried molases (T15); 3% dried molasses (T16); 1% dried molasses and 0.5% urea (T17); 2% dried molasses and 0.5% urea (T18); 3% dried molasses and 0.5% urea (T19); bacterial inoculant Biosilo (T20). pH was increased in T1 (5.36) and T5 (5.33). The other silages pH varied from 3.89 to 4.29 and were similar. The highest non protein nitrogen was observed in T3 and those which included urea, but this was not observed whem 3% of molasses was included. Most silage fermentations were towards lactic acid production and these results were similar. T2 and T3 showed higher butiric acid concentration than the others and T2 and T9 showed higher acetic acid production. In vitro dry matter digestibility coeficients were from 26.36 to 51.31%. Dry matter loss was higher on T2 (11.08%), T3 (10.50%) and T4 (9.8%).
  • Radiographic and densitometric aspects of the fracture healing treated
           with bone morphogenetic proteins in rabbit radius

    • Abstract: Avaliou-se, por meio de exames radiográficos e densitométricos, a influência de um biomaterial desenvolvido pela indústria brasileira, no processo de reparação de fraturas diafisárias instáveis do rádio. Foram utilizados 15 coelhos Norfolk, machos, idade entre cinco e seis meses e peso corpóreo médio de 3,5kg. Induziu-se fratura transversa na porção média da diáfise de ambos os rádios direito, por meio de serra giratória. Ao redor das extremidades fraturadas do rádio direito (tratado) aplicou-se BMPs adsorvidas à hidroxiapatita e aglutinante de colágeno em grânulos, ambos de origem bovina. O rádio esquerdo não recebeu tratamento, sendo considerado controle. Realizaram-se estudos radiográficos e de densitometria óptica por imagens radiográficas no pós-operatório imediato e aos 30, 60 e 90 dias de pós-operatório. Somente no 30º dia de pós-operatório ocorreu maior porcentagem de restabelecimento cortical na fratura tratada com biomaterial. Pela análise estatística não se verificou diferença nos exames densitométricos quer entre momentos ou entre membros. Foi possível concluir que apenas no exame radiográfico ao 30 dias de pós-operatório detectou-se efeito positivo do biomaterial.The aim of this study was to evaluate by radiographic and densitometric examinations the influence of a biomaterial developed by the Brazilian industry in the reparation process of unstable diaphyseal fracture of the radius. Fifteen Norfolk rabbits, males, age between five and six months, and average body weight of 3.5 kg were used. A transversal fracture was induced in the middle portion of the radial diaphysis of both forelimbs using a circular saw. The association of BMPs adsorbed to the hydroxiapatite and agglutinant of collagen in granules, both of bovine origin, were used around the fracture extremities of the right radius (treated). The left radius did not receive any treatment, and it was considered as control. Radiographic evaluation and optic densitometry by radiographic examinations were realized at immediate postoperative, and at 30, 60 and 90 days postoperative. Only at 30 days postoperative occurred higher percentage of cortical reestablishment of the fracture treated with biomaterial. By statistical analysis was not observed any difference in densitometric examinations in the different evaluation moments or between forelimbs. It was possible to conclude that only radiographic examination on day-30 postoperative was observed positive effect of the biomaterial.
