The infection occurs by ingesting sporulated oocysts that were eliminated in DH feces, by bradyzoites when ingested by IH meat or by tachyzoites when occur vertical transmission. In this study, 529 canine blood samples were collected, 120 at the municipality of Itabuna, and 409 at the municipality of Ilh?us. All blood samples of Itabuna were consisted of animals from domiciled urban areas. From Ilh?us, 96 were domiciled from urban areas, 135 were urban but strayed dogs from Centre for Zoonosis Control (CZC) and 178 were domiciled and from rural area. The Indirect hemagglutination test was used to test the presence of anti-T. gondii and a questionnaire were applied to the domiciled dog owners to analyze risk factors associated to the infection. From all 529 dogs, 193 were positive (36.5%). At Ilh?us 37.7% (154/255) and at Itabuna 32.5% (39/81) of animals were positive. The risk factors associated to the infection were localization, rural dogs had higher chance than urban (p=0.001), the behavior, the strayed urban dogs had more chance than the urban domiciled dogs (p=0.01), home-made food and meat ingestion (p= 0.034 and 0.027 respectively), race, the undefined race dogs had more risk (p=0.0001) and age, were the animals under five years old had a higher risk to the infection (p=0.009). The presence of veterinary assistance was considered as a protection factor. The logistic regression confirmed the habitat and age of the animals as the main risk factor associsted with the infection. / Toxoplasma gondii ? um parasito intracelular obrigat?rio que tem como hospedeiro definitivo membros da fam?lia Felidae e animais homeot?rmicos como hospedeiros intermedi?rios. A infec??o se d? pela ingest?o de oocistos esporulados eliminados nas fezes dos felinos, pela ingest?o de bradizo?tos nos tecidos dos HI ou ainda pela transmiss?o vertical de taquizo?tos. Neste estudo coletou-se sangue de 529 c?es, sendo 120 do munic?pio de Itabuna e 409 de Ilh?us. Todos os animais de Itabuna eram urbanos domiciliados. Dentre os c?es de Ilh?us, 96 eram urbanos domiciliados, 135 eram urbanos errantes provenientes do Centro de Controle de Zoonoses (CCZ), e 178 eram rurais domiciliados. Foi realizado o Teste de Hemaglutina??o Indireta (HAI) para analisar a presen?a de anticorpos anti-T.gondii e um question?rio foi aplicado junto aos propriet?rios dos animais domiciliados para avalia??o dos principais fatores de risco associados ? infec??o. Do total de 529 c?es, 193 foram positivos (36,5%). No munic?pio de Ilh?us 37,7% (154/255) e em Itabuna 32,5% (39/81) foram positivos. Os fatores de risco associados ? infec??o foram o habitat, onde os animais rurais tiveram maior risco do que os urbanos (p=0,001), o modo de vida, em que os animais urbanos errantes tiveram maior risco do que os urbanos domiciliados (p=0,01), ingest?o de comida caseira e de carne (p= 0,034 e 0,027, respectivamente), ra?a apresentando os SRD com maior risco (p=0,0001) e idade onde os animais acima de cinco anos tiveram maior risco (p=0,009). A presen?a de orienta??o do M?dico Veterin?rio se mostrou fator de prote??o (p=0,002). A regress?o log?stica confirmou como principais fatores de risco a idade e o habitat dos animais do estudo

Isolatings were performed from rhizosphere of vegetables and soil after harvest of cultivated species. The vast majority of the strains showed biochemical profiles identical to Pseudomonas (fluorescent group). While profiles identical to Burkholderia, Stenotrophomonas and Acinetobacter constituted other groups of representatives. Characterization of isolates took into account the capacity for synthesis of compounds possibly involved in mechanisms to stimulate plant growth, namely: biofilms, siderophores, acyl homoserine lactones (AHLs), indole-3-acetic acid (IAA) and indole related compounds, as well as solubilization of calcium phosphate. A total of 94 isolates were evaluated in the greenhouse for their ability to promote the growth of cabbage (Brassica oleracea var. acephala) in pots containing unsterilized loam soil. In addition, consortia were evaluated between components of the collection and rhizobia for the same purpose. In addition, it compared the effects of application of certain producing IAA isolates and the application of synthetic IAA on the growth of cabbage. Laboratory experiments showed that in vitro, 100% of the isolates formed biofilm, 71% synthesized siderophores, 31% produced AHLs, 95% produced IAA and 74% solubilized P. However, bioassays in the greenhouse showed that only 12% of the isolates induced significant responses to promote the growth of cabbage. Of these, a subgroup composed of 10 strains of rhizobacteria given increments in growth parameters of both the biomass and the root system of vegetables. Biofilms, siderophores, IAA and solubilization of P were common characteristics of the subgroup. No synergistic effect was observed among isolates in consortia, although it was found that the two strains of rhizobia consortium promoted the growth of inoculated plants. The isolates R1132 and S311 were higher than the application of synthetic IAA. The results suggested the potential of 12 bacteria to promote plant growth and increase production of cabbage / Uma cole??o de 189 isolados bacterianos, provenientes de sistema org?nico de produ??o de hortali?as, foi caracterizada com vistas ? sele??o de estirpes promotoras do crescimento de couve. Os isolamentos foram realizados a partir da rizosfera de hortali?as e do solo ap?s colheita das esp?cies cultivadas. A grande maioria das estirpes apresentou perfil bioqu?mico id?ntico a Pseudomonas (grupo fluorescente). Enquanto perfis id?nticos a Burkholderia, Acinetobacter e Stenotrophomonas constitu?ram outros grupos de representantes. A caracteriza??o dos isolados levou em conta a capacidade de s?ntese de compostos possivelmente envolvidos em mecanismos de est?mulo ao crescimento de plantas, a saber: biofilmes, sider?foros, acil-lactonas homoserinas (ALHs), ?cido indol-3-ac?tico (AIA) e compostos ind?licos relacionados, al?m da solubiliza??o de fosfato de c?lcio. Um total de 94 isolados foi testado na casa de vegeta??o quanto ? capacidade de promover o crescimento de couve (Brassica oleraceae var. acephala) em vasos contendo solo distr?fico n?o esterilizado. Paralelamente, foram avaliados cons?rcios entre componentes da cole??o e riz?bios para igual finalidade. Em adendo, foram comparados os efeitos da aplica??o de determinados isolados produtores de AIA e da aplica??o de AIA sint?tico sobre o crescimento da couve. Os experimentos de laborat?rio indicaram que, in vitro, 100% dos isolados formaram biofilme, 71% sintetizaram sider?foros, 31% produziram AHLs, 95% produziram AIA e 74% solubilizaram P. No entanto, os bioensaios na casa de vegeta??o evidenciaram que apenas 11% dos isolados bacterianos induziam respostas significativas de promo??o do crescimento da couve. Desses, um subgrupo formado por 10 estirpes de rizobact?rias conferiu incrementos nos par?metros de crescimento, tanto da biomassa a?rea quanto do sistema radicular da hortali?a. Biofilmes, sider?foros, AIA e solubiliza??o do P foram caracter?sticas comuns do subgrupo. N?o foi observado efeito sin?rgico entre os isolados em cons?rcios, embora tenha sido verificado que as duas estirpes de riz?bios consorciadas promoveram o crescimento das plantas inoculadas. Os isolados R1132 e S311 foram superiores ? aplica??o do AIA sint?tico. Os resultados obtidos sinalizaram o potencial de 12 bact?rias que promover o crescimento das plantas e incrementar a produ??o de couve.

Pesquisa do Estado do RJ - FAPERJ / Nitrogen is one of the nutrient elements most limiting for plant growth. Thus, increasing plant nitrogen usage efficiency (NUE) is an essential factor for sustainable agriculture, leading to an increased food production with less fertilizer input and less environment impact. NUE in plant involves the uptake and accumulation efficiency, and N use efficiency for grain production. Understanding the mechanisms regulating these processes is crucial for the improvement of NUE in crops. Therefore, is essential to comprehend plants response to different N regimes, mainly N limitation. The usage of plants or varieties with differences in nutrient use efficiency is another important factor to determine the main mechanisms involved in these processes. The objectives of this study were to evaluate N metabolism and expression of genes involved in N uptake and assimilitation of two rice varieties (Piau? and IAC-47), under different N supply conditions. The N metabolism was evaluated by quantification of nitrogen fractions in plant tissue and enzymatic activity, expression of genes that code for high and low affinity N transporters, and N assimilation enzymes. Two experiments were conducted: the first, to investigate the plants behavior when grown under high and low N supply; and the second to verify plants response to NO3 - resupply. The IAC-47 variety showed greatest mass accumulation in all treatments. When plants were grown for a long period under low N supply it was observed a higher nitrate (NO3 -) content in the tissue of Piau? variety, which is adapted to low fertility conditions, as well as a high activity of nitrate reductase and glutamine synthetase in the roots of these plants. When under high NO3 - supply for a long period, Piau? variety had higher NO3 - concentrations in roots and sheaths, but no differences were observed in enzymes activity. The nitrate transporters expression was higher in roots of Piau? plants under low supply of NO3 - when compared to Piau? plants under high N supply. Nitrate transporters expression in roots of IAC-47 plants showed a pattern opposite to the one observed for Piau? plants. When plants were resupplied with NO3 -, after a 72 hours period without N, there was a rapid increase, after 6 hours of resupply, in the expression of high affinity nitrate transporters genes (OsNRT2.1) and the plastidial glutamine synthetase (GS2) in the Piau? variety roots, and a higher expression of these in IAC-47 roots after a 24 hours of N resupply. The efficiency of Piau? variety is related to the differentiated control of N absorption and assimilation mechanisms, which allow bigger expression of high affinity nitrate transporters in tissue with high levels of soluble N, high N status, indicating that the control of nitrogen uptake system may be essential for the nitrogen usage efficient. / O nitrog?nio ? um dos elementos minerais que mais limita o desenvolvimento das plantas. Assim, aumentar a efici?ncia de uso de nitrog?nio (EUN) ? um fator ? essencial para uma agricultura sustent?vel, levando a um aumento da produ??o de alimentos com menor uso de insumos e menos impactos ao ambiente. A EUN envolve a efici?ncia de absor??o e ac?mulo e a efici?ncia de utiliza??o de N para produ??o. Compreender os mecanismos envolvidos nesses processos e como eles s?o controlados ? fundamental para a melhoria da EUN nas plantas cultivadas. Para isso, ? essencial entender a resposta e comportamento das plantas a diferentes regimes de N, principalmente ? limita??o de N. O uso de plantas ou variedades com diferen?as na EUN ? outro fator importante para verificar os principais mecanismos envolvidos. Este trabalho teve por objetivo desse trabalho foi verificar o metabolismo e a express?o de genes envolvidos na absor??o e assimila??o de nitrog?nio nas variedades de arroz Piau? e IAC-47 sob diferentes condi??es de disponibilidade desse nutriente. O metabolismo de N foi avaliado atrav?s da quantifica??o das fra??es nitrogenadas no tecido e atividade enzim?tica, a express?o de genes que codificam para transportadores de N de alta e baixa afinidade e enzimas de assimila??o de N. Foram realizados dois experimentos: o primeiro para verificar o comportamento das plantas quando cultivadas sob alto e baixo suprimento de N; e o segundo, para verificar as repostas ao ressuprimento de N. O ac?mulo de massa foi maior na variedade IAC-47 em todos os tratamentos. Quando as plantas foram cultivadas por um longo per?odo sob baixo suprimento de N foi observado maior teor de nitrato (NO3 -) no tecido da variedade Piau?, adaptada a condi??es de baixa fertilidade, assim como uma alta atividade da nitrato redutase e glutamina sintetase nas ra?zes dessas plantas. Sob alto suprimento de NO3 -, por um longo per?odo, a variedade Piau? apresentou maiores teores de NO3 - nas bainhas e ra?zes, mas n?o foram observas diferen?as na atividade de enzimas. A express?o dos transportadores de nitrato na variedade Piau? foi mais elevada nas ra?zes das plantas sob baixo suprimento de NO3 - quando comparado as plantas sob alto suprimento de N. Na variedade IAC-47 a express?o dos transportadores de NO3 - teve comportamento oposto ao observado para a Piau?. Quando as plantas receberam NO3 -, ap?s um per?odo de 72 horas sem N, houve um r?pido aumento, ap?s 6 horas do ressuprimento, na express?o do gene que codifica para o transportador de NO3 - de alta afinidade OsNRT2.1 e glutamina sintetase plastidial (GS2) nas ra?zes da variedade Piau?, e 24 horas ap?s o ressuprimento a express?o foi maior na variedade IAC-47. A efici?ncia da variedade Piau? esta relacionada ao controle diferenciado dos mecanismos de absor??o e assimila??o de N, que permite a maior express?o dos transportadores de nitrato de alta afinidade em tecido com altos teores de N sol?vel, alto status de N, indicando que o controle do sistema de absor??o de N pode ser essencial para a efici?ncia no uso de nitrog?nio.

Data sources were the five slaughterhouses under Federal Inspection Service in the state. The data were from 1 January 2002 to 31 December 2009 and were obtained in the Management Information System Federal Inspection Service in the state. The prevalence of condemnation was calculated per 100,000 cattle inspected. The chi-square for trend and linear regression were used. The chi-square was used to evaluate the significance of association between prevalence of the condemnation causes and establishment and differences between proportions of condemnation forequarters and hindquarters. The main causes of condemnation of carcasses were lesions suggestive of brucellosis and tuberculosis prevalence of 16 and 18/100,000 respectively. The historical trend in prevalence of brucellosis suggestive lesions was slightly up while in tuberculosis suggestive lesion was descending. The linear relationship between prevalence of tuberculosis and years studied was significant (p-value<0.01) but no significant difference for brucellosis (p-value = 0.53). The forequarters are more condemned than the hindquarters (p-value<0.01) and the main cause of condemnation is adenitis/lymphadenitis with prevalence of 09/100,000 and 03/100,000 for forequarters and hindquarters respectively. Traumatic injury was the second major cause of condemnation of forequarters (34x10-2) and third in hindquarters (60x10-2). Among the organs the most condemned is the lung (p=17,508/100,000) followed by kidney (10,800/100,000) while tongue (p=1,021/100,000) is the less condemned. Organs had as major condemnation cause the contamination, except lung and kidneys which had as first cause of condemnation emphysema (p=3,329/100,000) and anemic infarction (p=7,585/100,000) respectively. Historical trends condemnation of tongues, hearts, livers and head for contamination were rising. Lungs and kidneys showed historical trend contamination to condemnation downward. The cattle slaughtered under Federal Inspection Service in Maranh?o State had low prevalence of condemnation for pathological causes. Lesions suggestive of brucellosis and tuberculosis are the most important causes of carcasses condemnation and cause big economic losses. Nevertheless, other causes of condemnation such as adenitis/lymphadenitis traumatic injury and contamination must be considered, mainly because of its relationship with inadequate manage on farm and slaughterhouse by operations insufficiently controlled. Although market price of organs is lower than meat, the economic losses are higher for organs condemnation than carcasses due to the large number of organs condemnation / Os objetivos deste estudo foram conhecer a preval?ncia e a tend?ncia secular das principais causas de condena??o de carca?as e ?rg?os de bovinos abatidos no estado do Maranh?o e estimar as perdas econ?micas associadas. As fontes de dados foram os cincos matadouros frigor?ficos sob Servi?o de Inspe??o Federal do estado. Os dados de abate de bovinos e condena??o s?o referentes ao per?odo de 01 de janeiro de 2002 a 31 de dezembro de 2009 e foram obtidos mediante acesso ao Sistema de Informa??es Gerencias do Servi?o de Inspe??o Federal no estado. As preval?ncias de condena??o foram calculadas por 100.000 bovinos inspecionados. O teste de qui-quadrado para tend?ncia e a regress?o linear simples foram utilizados. O teste do qui-quadrado para independ?ncia foi utilizado para avaliar a signific?ncia da associa??o entre a preval?ncia das causas de condena??o e os estabelecimentos e as diferen?as entre as propor??es de condena??o de quartos traseiros e dianteiros. As preval?ncias de condena??o de carca?as e ?rg?os diferiram significativamente (p-valor<0,01) entre os estabelecimentos. As principais causas de condena??o de carca?as foram les?es sugestivas de brucelose e tuberculose com preval?ncia de 16 e 18/100.000, respectivamente. A tend?ncia hist?rica da preval?ncia de condena??o por les?o sugestiva de brucelose mostrou-se levemente ascendente enquanto que a da tuberculose descendente. A rela??o linear entre a preval?ncia de tuberculose e anos estudados foi significativa (pvalor< 0,01), mas sem diferen?a significativa para brucelose (p-valor=0,53). Os quartos os dianteiros foram mais condenados que os traseiros (p-valor<0,01) e as principais causas de condena??es foram adenite/linfadenite (p=09/100.000) para dianteiros e (p=03/100.000) para traseiros. Les?o traum?tica foi a segunda maior causa de condena??o de quartos dianteiros (p=34x10-2) e a terceira em traseiros (p=60x10-2). Dentre os ?rg?os, o mais condenado foi o pulm?o (p=17.508/100.000) seguido pelos rins (p=10.800/100.000) enquanto que a l?ngua (p=1.021/100.000) foi o menos condenado. A principal causa de condena??o de ?rg?os foi contamina??o, exce??o para os pulm?es e os rins que tiveram como principal causa de condena??o enfisema (p=3.329/100.000) e infarto an?mico (p=7.585/100.000), respectivamente. As tend?ncias de condena??o de l?nguas, cora??es, cabe?a e f?gados para contamina??o foram ascendentes. As principais causas de condena??o de pulm?es e rins foram enfisema (p=3.329/100.000) e infarto an?mico (p=7.585/100.000), respectivamente. Esses dois ?rg?os apresentaram tend?ncia descendente para condena??o por contamina??o. O rebanho bovino abatido sob o Servi?o de Inspe??o Federal do Estado do Maranh?o apresentou baixas preval?ncias de condena??es por causas patol?gicas. Les?es sugestivas de brucelose e tuberculose s?o as causas de condena??o de carca?as que trazem maiores perdas econ?micas. Outras causas de condena??o como adenite/linfadenite les?o traum?tica e contamina??o revelam manejos inadequados na fazenda e opera??es de abate insuficientemente controladas pelos matadourosfrigor?ficos. As altas preval?ncias de condena??o de ?rg?os por contamina??o revelam descuido dos estabelecimentos, no processo de obten??o desses nas linhas de abate indicando necessidade de interven??o nos pontos cr?ticos de contamina??o e melhor treinamento dos funcion?rios dos frigor?ficos. Embora o pre?o de mercado de ?rg?os seja menor que o da carne com osso, as perdas econ?micas estimadas para estes foram duas vezes maior que as resultantes da condena??o carca?as.

The pyrazole compounds are the drugs of synthetic origin in their chemical structure consisting of a ring pirazol?nico, with which several studies show the effectiveness in controlling of pain, fever and inflammation. The need to develop new drugs with analgesic and anti-inflammatory, low cost and which have few adverse reactions, has stimulated the synthesis and study of pharmacological activities of pyrazole compounds. With this objective, we studied the antinociceptive and anti-inflammatory potential of compound 1.5-diphenyl-pyrazole-3-hidrazinopirazol(a) (DHP), administered orally in pharmacological models of the acetic acid writhing, tail-flick, formalin, ear edema induced by croton oil and carrageenan-induced peritonitis in mice, and mechanical allodynia (von Frey) and thermal hyperalgesia (Hargreaves) in rats. The administration of DHP (1, 3 and 10mg/kg) decreased in a dose-dependent (41.3, 62.7 and 76%) number of writhing (ID50 = 1.3mg/kg). In the tail-flick test, DHP (10mg/kg) was ineffective and the application of positive control fentanyl (200?g/kg, sc) increased the latency to thermal stimulation in up to 138%. Without changing the first phase of nociception (neurogenic pain) of the formalin test, DHP (10mg/kg) and the positive control indomethacin (10mg/kg, p.o.) inhibited the reactivity in the 2 phase (ndinflammatory pain) in 40.9 and 48.7% respectively. This same dose of DHP reduced by 54% the ear edema induced by croton oil, as well as the positive control, dexamethasone (2mg/kg, sc) at 55.3%. Also in a dose-dependent DHP (3, 10 and 30 mg / kg) inhibited by 11.8, 39 and 53.7%, respectively, leukocyte migration in peritonitis induced by carrageenan test (ID50 = 22.9mg/kg). In the assessment of mechanical allodynia incision group treated with DHP (GIDHP - 10mg/kg) showed a significant reversal of allodynia (RA) after one hour of administration, with maximum reading RA for 12 hours (28.2%) in the second stage of the experiment, remaining in the third stage with RA of 26.9, 43.4 and 60.4% in the 7th, 10th and 14th days of evaluations, when compared with the vehicle group incised (GIV). In thermal hyperalgesia GIDHP (10mg/kg) also significantly reversed the hyperalgesia (RH) after one hour of treatment, with RH maximum of three hours in reading (68.9%) in the second stage, obtaining in the third stage RA of 43.4, 32,1 and 64% in 7th, 10th and 14th days of evaluations, when compared to the GIV and obtaining similar values of the group not incised vehicle (GNIV) on 14 dayth. In the von Frey and Hargreaves GNIV showed similar readings in the three stages of the experiment. The DHP (10mg/kg) did not alter the motor activity of mice in rota-rod test. Whereas the compound DHP showed antinociceptive activity in writhing test, antiedematogenic in ear edema, inhibited the 2nd phase of nociception (inflammatory pain) in formalin test and leukocyte migration, promoting reversal of hypernociception in models of thermal hyperalgesia and allodynia mechanics, these results indicate that the effectiveness of DHP involves the participation of anti-inflammatory mechanisms and create favorable outlook for its future use with this therapeutic goal. / A inflama??o ? um processo fisiol?gico de resposta org?nica diante de les?o tissular ou infec??o, gerando a dor como caracter?stica constante. Os compostos piraz?licos s?o drogas de origem sint?tica com um anel pirazol?nico na sua estrutura qu?mica, com os quais diversos estudos demonstram a efic?cia no controle da dor, da febre e da inflama??o. A necessidade do desenvolvimento de novos f?rmacos com propriedades analg?sicas e anti-inflamat?rias, de baixo custo e que apresentem poucas rea??es adversas, tem estimulado a s?ntese e o estudo das atividades farmacol?gicas dos compostos piraz?licos. Com esse objetivo, foi estudado o potencial antinociceptivo e anti-inflamat?rio do composto piraz?lico 1,5-difenil-3-hidrazinopirazol(a) (DHP), administrado pela via oral, nos modelos farmacol?gicos das contor??es abdominais pelo ?cido ac?tico, tail-flick, formalina, edema de orelha induzido pelo ?leo de cr?ton e peritonite induzida pela carragenina em camundongos; e na alodinia mec?nica (von Frey) e hiperalgesia t?rmica (Hargreaves) em ratos. A administra??o do DHP (1, 3 e 10mg/kg) diminuiu de maneira dose-dependente (41,3, 62,7 e 76%) o numero de contor??es abdominais (ID50=1,3mg/kg). No teste de tail-flick, DHP (10mg/kg) n?o foi efetivo e a aplica??o do controle positivo fentanil (200?g/kg, s.c.) ampliou a lat?ncia ao est?mulo t?rmico em at? 138%. Sem alterarem a 1? fase de nocicep??o (dor neurog?nica) do teste da formalina, o DHP (10mg/kg) e o controle positivo indometacina (10mg/kg, p.o.) inibiram a reatividade na 2? fase (dor inflamat?ria) em 40,9 e 48,7% respectivamente. Essa mesma dose do DHP reduziu em 54% o edema de orelha induzido pelo ?leo de cr?ton, assim como o controle positivo dexametasona (2mg/kg, s.c.) em 55.3%. Tamb?m de forma dose-dependente o DHP (3, 10 e 30 mg/kg) inibiu em 11,8, 39 e 53,7% respectivamente, a migra??o de leuc?citos no teste da peritonite induzida pela carragenina (ID50=22,9mg/kg). Na avalia??o da alodinia mec?nica o grupo incisado tratado com o DHP (GIDHP - 10mg/kg) apresentou significativas revers?es da alodinia (RA) ap?s uma hora da administra??o, com RA m?xima na leitura de 12 horas (28,2%) na segunda etapa, mantendo-se na terceira etapa com RA de 26,9, 43,4 e 60,4% nos 7?, 10? e 14? dias de experimenta??o, comparados com o grupo incisado ve?culo (GIV). Na hiperalgesia t?rmica o GIDHP tamb?m produziu revers?o da hiperalgesia (RH) uma hora ap?s o tratamento, com RH m?ximo na leitura de 3 horas (68,9%) na segunda etapa, mantendo-se na terceira etapa com RH de 43,4, 32,1 e 64% nos 7?, 10? e 14? dias de experimenta??o, quando comparados ao GIV e obtendo valores semelhantes ao grupo n?o incisado ve?culo (GNIV) no 14? dia. No von Frey e no Hargreaves o GNIV apresentou leituras semelhantes nas tr?s etapas do experimento. O DHP (10mg/kg) n?o alterou a atividade motora de camundongos no teste do rota-rod. Considerando que o composto DHP apresentou atividade antinociceptiva no teste das contor??es, antiedematog?nica no edema de orelha, inibiu a 2? fase de nocicep??o (dor inflamat?ria) do teste da formalina e a migra??o leucocit?ria, promovendo ainda revers?o da hipernocicep??o nos modelos de hiperalgesia t?rmica e alodinia mec?nica; esses resultados indicam que a efetividade do DHP envolve a participa??o de mecanismos anti-inflamat?rios e criam perspectivas favor?veis para sua futura utiliza??o com esse objetivo terap?utico.

Both groups were analyzed during a pre-determined period of time totalizing 28 days of observation and analysis. The following enzymes activity levels were determined: Aminotransferase (AST), Alanina-Aminotransferase (ALT), Gamma Glutamyl Transpeptidase (GGT) and Alkaline Fosfatasis (FA); serum levels of Albumin (A), Total Bilirrubin (BT) and Total Serum Proteins (PT), yet registering Respiratory (FR) and Heart Rate (FC), Systolic Blood Pressure (PAS), Mean Arterial Blood Pressure (PAM), Diastolic Blood Pressure (PAD) and Oxygen Partial Saturation (SPO2). Twenty healthy cats were analyzed on this study, their weights varying from two to four kilos and ages between three to five years old, submitted to experimental procedures performed during the months of January and February, 2010. The analysis of these results showed a major difference (p<0,05) between the ALT serum activities at the following positions: T2 (30 minutes), T3 (60 minutes), T5 (12 hours) and T9 (28 days); AST serum activities at T2, FA serum activities at T2, T6 (seven days) and T8 (21 days), emphasizing the fact only at this last position the GP levels were greater than GC; in the heart rate at T1 position (the beginning of this experiment), without compromising animals physical condition. None of the animals presented averages above parameters of normality. The other parameters examined did not present any significant differences, concluding that total intravenous anesthesia using continuous infusion of propofol was safe to contain cats in invasive surgical procedures, therefore providing more information regarding the safe use of this drug in animals. / O trabalho foi desenvolvido no Hospital de Cl?nicas Veterin?rias do Centro Universit?rio Pl?nio Leite, em Itabora?, RJ, com o intuito de monitorar perfil bioqu?mico hep?tico e par?metros cl?nicos de gatos submetidos ? infus?o cont?nua de propofol (GP) na dose de 0,3 mg/kg/min, durante 90 minutos, e comparando-se com resultados observados em gatos do grupo controle (GC), que receberam infus?o cont?nua de solu??o fisiol?gica. Os dois grupos foram avaliados em espa?os de tempo pr?-determinados, totalizando 28 dias de observa??es e an?lises. Foram determinadas as atividades s?ricas de aspartatoaminotransferase (AST), alanina-aminotransferase (ALT), gama-glutamil transpeptidase (GGT) e fosfatase alcalina (FA), determinadas as concentra??es s?ricas de Albumina (A), Bilirrubina total (BT) e Prote?nas Totais s?ricas (PT), registrando-se ainda as Frequ?ncias Respirat?rias (FR) e Card?acas (FC), Temperatura Retal (T), Press?es Arteriais Sist?licas (PAS), M?dias (PAM) e Diast?licas (PAD) e Satura??o parcial de O2 (SPO2). Foram utilizados no estudo 20 gatos h?gidos, com pesos variando entre dois e quatro kg e idades entre tr?s e cinco anos, que foram submetidos aos procedimentos experimentais no per?odo compreendido entre janeiro e fevereiro de 2010. A an?lise dos resultados demostraram que houve diferen?a significativa (p<0,05) nas atividades s?ricas de ALT nos momentos T2 (30 minutos), T3 (60 minutos), T5 (12 horas) e T9 (28 dias); nas atividades s?ricas de AST no momento T2; nas atividades s?ricas de FA nos momentos T2, T6 (7 dias) e T8 (21 dias), sendo que, somente neste ultimo momento as dosagens do GP foram maiores que no GC; na frequ?ncia card?aca no momento T1 (in?cio do experimento), sem causar qualquer comprometimento ? sa?de dos animais. Nenhum dos animais apresentou m?dias acima dos par?metros de normalidade. Os outros par?metros analisados n?o tiveram diferen?as significativas, concluindo-se que a anestesia intravenosa total com uso de propofol em infus?o cont?nua foi segura para conten??o de gatos em procedimentos incruentos, contribuindo assim para maiores informa??es em rela??o ao uso desse f?rmaco nesses animais

The total of 516 records in 10 host species of genus was compiled. Were included in the list of new geographic records monogeneans parasites of Pimelodus maculatus Lac?p?de, 1803 collected from Midwest, Southeast and South of Brazil. New morphological data of Cucullanus pinnai pinnai Travassos, Artigas & Pereira, 1928, parasite of P. maculatus collected in the Guandu river, in the State of Rio de Janeiro have been reported. This work noted that the position of the excretory pore and deirids of the specimens are at the level or posterior to the oesophagus- intestine junction in the most specimens and gubernaculums size is greater than in other previously studied of C. pinnai pinnai. Nematodes were studied using light and scanning electron microscopy (SEM) and differential interference contrast (DIC) and analyzes confirmed morphological details of the cephalic region and the caudal papillae that species. Comparative study of parasitic communities of P. maculatus was also performed. 50 specimens of the P. maculatus were collected from Guandu river, in the State of Rio de Janeiro and others 50 from Mogi-Gua?? river, State of S?o Paulo. In the samples from Guandu river were identified the following species: Ameloblastella paranaensis Fran?a, Isaac, Pavanelli & Takemoto, 2003 (P= 8%; MI= 1,0?0,0); A. satoi Monteiro, Kritsky, Brasil-Sato, 2010 (P= 8%; MI= 1,0?0,0); Demidospermus bidiverticulatum Suriano & Incorvaia, 1995 (P= 8%; MI= 1,0?0,0); D. paravalenciennesi Guti?rrez & Suriano, 1992 (P=90%; MI=14,77?5,04), D. uncusvalidus Guti?rrez & Suriano, 1992 (P=90%; MI=12,37?4,86), D. valenciennesi Guti?rrez & Suriano, 1992 (P=56%; MI=6,06?3,95) e Cucullanus pinnai pinnai Travassos, Artigas & Pereira, 1928 (P=64%; MI=3,28?4,87). In the rio Mogi-Gua?? the parasites identified were: Ameloblastella paranaensis (P= 8%; MI= 1,0?0,0), Ameloblastella satoi (P= 8%; MI= 1,0?0,0), Demidospermus paravalenciennesi (P=86%; MI=18,58?10,79), D. uncusvalidus (P=84%; MI=16,73?7,74), D. valenciennesi (P=52%; IM=6,84?4,55) e Cucullanus pinnai pinnai (P= 44%; MI= 3,88?4,87). The females of P. maculatus had higher weight and length of males in both samples. The sex and o length of the hosts did not influence the level of parasitism. Positive correlation was observed between weight of host and abundance of D. uncusvalidus only in the sample of the Guandu river. Aggregate distribution was observed in all the prevalent species of metazoan parasites of P. maculatus in the two localities. D. paravalenciennesi showed a higher frequency of dominance and relative dominance in the samples of Guandu river and D. uncusvalidus in the samples of Mogi-Gua?? river. The results of the qualitative similarity index Jaccard (CJ) and quantitative Sorensen (CS) within the collected samples were homogenea. The Jaccard index indicated heterogeneity while Sorensen index indicated homogeneity between samples. The results demonstrated that the relationship between parasites and their hosts are constant even in different river basins. / Uma lista de esp?cies de metazo?rios associados ao g?nero Pimelodus Lac?p?de, 1803 foi elaborada neste trabalho. O total de 516 registros em 10 esp?cies de hospedeiros do g?nero foi compilado. Foram inclu?dos na lista novos registros de geogr?ficos de parasitos monogen?ticos de Pimelodus maculatus Lac?p?de, 1803 coletados nas regi?es Centro-oeste, Sudeste e Sul do Brasil. Novos dados morfol?gicos de Cucullanus pinnai pinnai Travassos, Artigas & Pereira, 1928, parasito de P. maculatus coletado no rio Guandu, no Estado do Rio de Janeiro foram relatados. Foi observado que a posi??o do poro excretor e deir?deos nos esp?cimes estudados s?o posteriores ao final do es?fago na maioria dos esp?cimes e o tamanho do gubern?culo ? maior do que em outros de C. pinnai pinnai estudados anteriormente. Os nematoides foram estudados utilizando microscopia eletr?nica de varredura (MEV) e contraste interferencial de fase (DIC) e as an?lises confirmaram detalhes morfol?gicos da regi?o cef?lica e as papilas caudais dessa esp?cie. Estudo comparativo das comunidades parasit?rias de P. maculatus tamb?m foi realizado. Foram coletados 50 esp?cimes de P. maculatus no rio Guandu, no Estado do Rio de Janeiro e outros 50 exemplares no rio Mogi-Gua??, no Estado de S?o Paulo, foram examinados para o estudo de sua parasitofauna, no per?odo de maio ? dezembro de 2012. No rio Guandu foram coletadas as seguintes esp?cies: Ameloblastella paranaensis Fran?a, Isaac, Pavanelli & Takemoto, 2003 (P= 8%; IM= 1,0?0,0); A. satoi Monteiro, Kritsky, Brasil-Sato, 2010 (P= 8%; IM= 1,0?0,0); Demidospermus bidiverticulatum Suriano & Incorvaia, 1995 (P= 8%; IM= 1,0?0,0); D. paravalenciennesi Guti?rrez & Suriano, 1992 (P=90%; IM=14,77?5,04), D. uncusvalidus Guti?rrez & Suriano, 1992 (P=90%; IM=12,37?4,86), D. valenciennesi Guti?rrez & Suriano, 1992 (P=56%; IM=6,06?3,95) e Cucullanus pinnai pinnai Travassos, Artigas & Pereira, 1928 (P=64%; IM=3,28?4,87). No rio Mogi-Gua?? os parasitos identificados foram: Ameloblastella paranaensis (P= 8%; IM= 1,0?0,0), Ameloblastella satoi (P= 8%; IM= 1,0?0,0), Demidospermus paravalenciennesi (P=86%; IM=18,58?10,79), D. uncusvalidus (P=84%; IM=16,73?7,74), D. valenciennesi (P=52%; IM=6,84?4,55) e Cucullanus pinnai pinnai (P= 44; IM= 3,88?4,87). As f?meas de P. maculatus apresentaram peso e comprimento maiores que dos machos nas duas amostras. O sexo e o comprimento dos hospedeiros n?o influenciaram o n?vel de parasitismo. Correla??o positiva foi observada entre o peso e a abund?ncia de D. uncusvalidus somente na amostra do rio Guandu. Foi observada distribui??o agregada de todas as esp?cies mais prevalentes de metazo?rios parasitos de P. maculatus nas duas bacias de coleta. D. paravalenciennesi apresentou maior freq??ncia de domin?ncia e domin?ncia relativa no rio Guandu e D. uncusvalidus no rio Mogi-Gua??. Os resultados dos ?ndices de similaridade qualitativa de Jaccard (CJ) e quantitativa de Sorensen (CS) dentro das amostras coletadas demonstraram homogeneidade. O ?ndice Jaccard indicou heterogeneidade e o ?ndice de Sorensen indicou homogeneidade entre as amostras. Os resultados demonstram que o relacionamento entre parasitos e seus hospedeiros s?o constantes, mesmo em diferentes bacias hidrogr?ficas.

This research aimed to utilize Eucalyptus urophylla S.T. Blake callus for lignin production. This callus were obtained from stems segments explants grown in culture medium added with a combination of the cytokine TDZ and the auxins acid indole-3-acetic (IAA), acid ?-naphthaleneacetic (NAA) and acid 2,4-dichlorophenoxyacetic (2,4-D). This growth regulators were utilized either alone or mixtured. For cell suspension production it was utilized callus obtained in medium culture added with 20?M IAA + 3?M TDZ, after 30 days of growth in vitro. Once the cells suspension was obtained, the lignin production was induced by four elicitors: jasmonic acid (JA), NAA, sucrose and control (without elicitor). It was used a completely randomized design with four replications. Each plot consisted of an Erlenmeyer with 125 ml of cells suspension culture. The Wiesner test confirmed the lignin presence in all treatments. In 3 of the 4 replicatons it was performed another evaluation to the production of DHPs (polymers by oxidative dehydrogenation) utilizing suspension filtrate added with H2O2, H2O2 + peroxidase and peroxidase. These new treatments were analyzed through polilignols production utilizing infrared (IR) and nuclear magnetic resonance of the hydrogen (NMR H). The suspension filtrate analysis of the 4th replication through ultraviolet (UV), IR, NMR 13C and NMR H evidenced the production of extra cellular lignin. Of this, the largest content was obtained in presence of sucrose as elicitor, followed by ANA and AJ. The cells in suspension increased the cellular wall lignin content in all treatments in relation to the control and the largest values were with the medium containing sucrose. DHPs were also analyzed utilizing as mattress the MS medium added of the same elicitors tested in the cellular suspension phase. For this, it was utilized as precursors the following alcohols: coniferyl or sinapyl, H2O2 and peroxidase; amd the analyses were done in RMN H and RMN 13C. The results showed DHPs synthesis of both coniferyl alcohol (DHP1c, DHP2c and DHP4c) and sinapyl alcohol (DHP2s). Nevertheless, It was not synthesized DHP in the treatment containing sucrose when the precursor was the coniferyl alcohol. On the other hand, when the sinapyl alcohol was the precursor, DHPs were only synthesized in the presence of ANA as elicitor. It was concluded that sucrose is an appropriate elicitor for the lignin production in cells suspension both at cellular and extra cellular level. However, this result was not observed in relation to DHP production. NAA auxin had a better functionality in the DHP2c and DHP2s formation. These results may be considered a progress in the lignification studies with the use of E. urophylla cell suspension. Once all these questions were answered and solved, it will be possible to develop E.urophylla suitable plants with better quality forest products and able to cause smaller environmental impact in the industrial processes. / Apesar dos avan?os tecnol?gicos, a compreens?o da forma??o estrutural da lignina ainda ? alvo de in?meras investiga??es cient?ficas. Esta pesquisa foi realizada com calos de Eucalyptus urophylla S.T. Blake para a produ??o de lignina. Os calos foram obtidos a partir de explantes de segmentos caulinares desenvolvidos em meios de cultura acrescidos de uma combina??o da citocinina TDZ e das auxinas ?cidos: 3-indolac?tico (AIA), ?-naftalenoac?tico (ANA) e diclorofenoxiac?tico (2,4-D), nas formas isoladas e conjugadas. Para a produ??o de c?lulas em suspens?o foram utilizados os calos formados no tratamento contendo 20?M de AIA + 3?M de TDZ, ap?s 30 dias de cultivo in vitro. Obtidas as c?lulas em suspens?o, a produ??o de lignina foi induzida empregando-se quatro elicitores: ?cido jasm?nico (AJ), ANA, sacarose e testemunha (sem o emprego de elicitores). O delineamento experimental utilizado foi o inteiramente casualizado, 4 repeti??es e um Erlenmeyer contendo 125 ml de cultura de c?lulas em suspens?o. O teste de Wiesner confirmou a presen?a de lignina, em todos os tratamentos testados. Em 3 das 4 repeti??es foram realizados subtratamentos para a produ??o de DHPs (pol?meros por desidrogena??o oxidativa) a partir do filtrado da suspens?o com H2O2, H2O2 + peroxidase e peroxidase. A an?lise desses subtratamentos foi realizada pela detec??o da produ??o de polilign?is atrav?s de raios infravermelho (IV) e resson?ncia magn?tica nuclear do hidrog?nio (RMN H). O filtrado da suspens?o da repeti??o 4 foi analisado por ultravioleta (UV), IV, RMN 13C e RMN H, sendo constatada a presen?a de lignina extracelular, com o maior teor sendo observado na presen?a do elicitor sacarose, seguido do ANA e AJ. As c?lulas em suspens?o apresentaram aumento no teor de lignina na parede celular em todos os tratamentos em rela??o ? testemunha e os maiores valores foram com o meio contendo sacarose. Foram analisadas tamb?m as DHPs tendo como colch?o o meio de cultura MS acrescido dos mesmos elicitores testados na fase de suspens?o celular. Para isto foram utilizados como precursores os ?lcoois conifer?lico ou sinap?lico, H2O2 e peroxidase, com a lignina analisada em RMN H e RMN 13C. Os resultados mostraram que houve s?ntese de DHPs do ?lcool conifer?lico (DHP1c, DHP2c e DHP4c) e do ?lcool sinap?lico (DHP2s). Porem quando se utilizou como precursor o ?lcool conifer?lico n?o foram sintetizadas DHPs no tratamento contendo sacarose como elicitor. E, quando foi utilizado como precursor o ?lcool sinap?lico, somente foram formadas DHPs na presen?a do elicitor ANA. Concluiu-se, ent?o, que a sacarose apresentou-se como um elicitor adequado para a produ??o de lignina nas c?lulas em suspens?o, tanto em n?vel celular quanto extracelular. Entretanto, isto n?o foi observado em rela??o ? produ??o de DHP. A auxina ANA teve funcionalidade maior na forma??o de DHP2c e DHP2s. Estes resultados devem ser considerados como um avan?o nos estudos de lignifica??o com a utiliza??o de c?lulas em suspens?o de E. urophylla. Quando esses questionamentos forem identificados e solucionados ser? poss?vel o desenvolvimento de novos indiv?duos desta esp?cie que conduzam ? produ??o de produtos florestais de melhor qualidade, com menor impacto ambiental nos processos industriais.

Sporotrichosis is the most common human subcutaneousmycosis in Latin America. In domestic feline, tissues can be found with a abundance of this parasite, fact that it is not usual in other species, so becoming a significantzoonoticagent. The objective in this study was to evaluate the regressiontimeoftheclinical disease, the side effects with Potassium Iodide (KI) administration, in dosis of 10 and 20mg/kg of weight, also evaluation the total T4 hormone concentrations, as well as the possible alterations of hemogram, and renal and hepatic serum biochemistrybyusingthismedication. Were used in this experimentation 14 domestic cats (Felis catusdomesticus), 11 males and three females, with indefinite race, and a mean age of 3.7 years old and average weight of 3.9 kg, with the disease sporotrichosis, all from Rio de Janeiro city. The animal selection was done through the confirmation of the sporotrichosis disease, by collecting material and conducting to mycological culture procedure. The animals were divided into two groups randomly: group I (10 mg of KI/ kg of weight), and group II (20 mg of KI/ kg of weight). Clinical and laboratory evaluations were performed in all cats in the study. Besides the total T4, the following laboratory tests were performed: hemogram, urea, creatinine, alkaline phosphatase, alanine-aminotransferase, gamma-glutamyltransferase, aspartate-aminotransferase. All tests were repeated every 15 days, and clinical evaluation was performed daily. This study concluded after comparison between the two groups that weren?t significant alterations in time regression of disease, as well as in that laboratorial analysis, but there were differences in side effects, so, dosis of 10 mg / kg of weight, once daily was the most right treatment of feline sporotrichosis / O Spotrhrix schenckii, agente etiol?gico da esporotricose,? amplamente disperso na natureza, especialmente em ambientes de climas temperados e tropicais. A esporotricose ? a micose subcut?nea humana mais comum na Am?rica Latina, e o felino tem potencial zoon?tico significativo. O objetivo deste trabalho foi avaliar o tempo de regress?o da doen?a cl?nica e as fun??es hep?tica, renal e tiroideana, com uso do iodeto de pot?ssio (IK) nas doses de 10 ou 20 mg/kg de peso, para tratamento da micose.

In these situations, large number of people may be exposed to serious health risks, even before entering combat. Therefore, the objective of this study was to investigate the practices to be implemented to enhance biosecurity related to water supply, food service and waste management in the campaign. To this end, it was raised the processes and issues of interest to health by non-participant observation of four campaign activities conducted at the Military Academy of Agulhas Negras (AMAN), from June to November 2010. A specific checklist was developed and implemented in the first three activities were subsequently produced a Manual of Good Practice. In order to validate this document, an instruction was given on topics related to the military involved. Subsequently, a new application of the checklist was performed in a final activity to compare the results. In parallel, were analyzed for microbiological and physical-chemical water consumption in all the activities together. Furthermore, it was evaluated the cleanliness of water tanks by aerobic mesophilic count and the presence or absence of coliform bacteria. Tabulated the results confirmed the trend of improvement in the overall situation of biosecurity. It was concluded therefore that the application of good practices, consolidated in the proposed manual, can increase levels of biosecurity of troops on campaign in the Brazilian Army. / O presente trabalho trata das quest?es higi?nico-sanit?rias nas atividades de campanha do Ex?rcito Brasileiro.

Por essa raz?o, o objetivo deste estudo foi investigar as pr?ticas a serem implementadas para se aumentar a biosseguran?a relacionada ao suprimento de ?gua, servi?o de alimenta??o e gest?o de res?duos em campanha. Para tal, foram levantados os processos e assuntos de interesse sanit?rio pela observa??o n?o-participante de quatro atividades de campanha realizadas na Academia Militar das Agulhas Negras (AMAN), de junho a novembro de 2010. Uma lista de verifica??o espec?fica foi elaborada e aplicada nas tr?s primeiras atividades sendo, posteriormente, produzido um Manual de Boas Pr?ticas. No sentido de validar este documento, uma instru??o sobre assuntos correlatos foi ministrada aos militares envolvidos. Posteriormente, uma nova aplica??o da lista de verifica??o foi realizada em uma ?ltima atividade para comparar os resultados. Paralelamente, foram realizadas an?lises microbiol?gicas e f?sico-qu?micas da ?gua de consumo de todas as atividades acompanhadas. Al?m disso, foi avaliada a higieniza??o dos reservat?rios de ?gua atrav?s da contagem de mes?filos aer?bios e da presen?a ou aus?ncia de bact?rias do grupo coliforme. Tabulados os resultados, confirmou-se a tend?ncia de melhoria na situa??o geral de biosseguran?a. Concluiu-se, portanto, que a aplica??o das boas pr?ticas, consolidadas no Manual proposto, ? capaz de aumentar os n?veis de biosseguran?a de uma tropa em campanha no ?mbito do Ex?rcito Brasileiro.
