Curandeirismo e o campo da saúde no Brasil

O objetivo geral do presente artigo é colaborar para a discussão sobre o campo da saúde. Especificamente, pretende-se contribuir para a reflexão do poder médico hegemônico e suas relações com as práticas relacionadas às curandeirices. Considerando a teoria do campo e do habitus de Pierre Bourdieu, discute-se sobre o curandeirismo com base em uma revisão do conceito de transe no campo intelectual como objeto do habitus científico formado entre a prática médica e a prática religiosa. Finalmente, por meio de temas contemporâneos compartilhados pelas Ciências Sociais e pela Saúde Coletiva, indica-se como o curandeirismo - aspecto negativo para o campo médico - transforma-se em aspecto positivo no campo da Saúde Coletiva.

Contaminação de praças públicas de Campo Grande, Mato Grosso do Sul, Brasil, por ovos de Toxocara e Ancylostoma em fezes de cães

De fevereiro a outubro de 1998, avaliou-se a contaminação de praças públicas de Campo Grande, MS, Brasil, por ovos de Toxocara e Ancylostoma, em amostras de fezes de cães. Das 74 praças examinadas, 42 (56,8%) estavam contaminadas por ovos de Ancylostoma, 8 (10,8%) com ovos de Toxocara e 7 (9,5%) com ambos.

Avaliação do comportamento sexual em touros Nelore: comparação entre os testes da libido em curral e do comportamento sexual a campo

Objetivou-se determinar a eficiência do teste da libido realizado em curral em comparação ao teste realizado a campo e relacioná-los à taxa de gestação em estação de monta de 120 dias. Treze touros aptos à reprodução foram submetidos ao teste da libido em curral por 3 horas. Desses touros, nove foram submetidos à avaliação a campo na proporção touro:vaca de 1:33. A cada 21 dias, foi diagnosticada a gestação por meio de avaliações ultra-sonográficas. No teste em curral, observou-se que, quanto maior o tempo, maiores foram os escores de classificação e que nenhum touro efetuou serviço completo nos 10 minutos iniciais do teste. Com um touro classificado como muito bom obteve-se 84,80% de prenhez, porém touros questionáveis proporcionaram taxas de prenhez de 86,67 e 96,55% ao final da estação. As correlações entre características físicas e morfológicas do sêmen mantiveram-se próximas de zero ou foram nulas. Os principais sinais fisiológicos do comportamento sexual foram o ato de cheirar ou lamber o corpo da fêmea, cheirar ou lamber a vulva, seguidos ou não por reflexo de Flehmen. em animais da raça Nelore, o tempo de 30 minutos de observação mostrou-se mais eficiente para a realização do teste da libido em curral. O teste da libido realizado a campo no período diurno não foi eficaz em predizer a libido de todos os animais estudados, em decorrência, provavelmente, do comportamento sexual noturno de alguns reprodutores.

Polycyclic aromatic hydrocarbons and other selected organic compounds in ambient air of Campo Grande City, Brazil

Fourteen samples of particulate matter and semi-volatile organic compounds were collected during 6 months in the city of Campo Grande, South Mato Grosso State, Brazil. Particle-bound polycyclic aromatic hydrocarbons (PAHs) were collected on Fluoropore PTFE filters and gas-phase PAHs were collected into sorbent tubes with XAD-2 resin. Both types of samples were extracted with a dichloromethane/methanol mixture (4:1 v/v), then the extracts were subjected to gas chromatography-mass spectrometry (GC-MS) analysis. PAHs, oxidized PAH (oxy-PAHs), phenols and methoxyphenols were identified by use of GC retention indices and MS files. The average value obtained for the sum of 15 PAHs was 21.05 ng m(-3) (range: 8.94-62.5 ng m(-3)). The presence of specific tracers and calculations of characteristic ratios (e.g. [Phe]/[Phe] + [Ant]) were used to identify the sources of the emissions of PAHs in the atmospheric samples. Levoglucosan (the anhydride of beta-glucose), retene (1-methyl-7-isopropylphenanthrene) and methoxyphenols (derivatives of syringol and guaiacol) and tracers for wood burning were identified. This study demonstrates that biomass burning from the rural zone is the main source of PAHs and emissions of other substances in the investigated site of Campo Grande. (c) 2004 Elsevier Ltd.

Maturação de sementes de aveia-preta (Avena strigosa Schreb). I. Maturidade do campo

The present work aimed to define the field maturity of Avena strigosa Schreb seeds cv. Comum. Three experiments were carried out in field conditions during 1986, 1987 and 1989 in Botucatu, SP, Brazil. The sowings were made in May. The characteristics evaluated were: panicles and spikelet aspects, the weight of the dry matter of 100 seeds with and without glumes, the seed moisture, the percentage of germinated seeds (sum of normal + abnormal seedlings), the percentage of germination and vigor (first count of germination test). Based on the dry matter accumulation and the gemination percentage of the seeds, it was concluded that the field maturity of the seeds was reached around 28 and 3 5 days after 100% of panicles emergence of the field. At this stage, the field presented a few percentage of particles (+/- 20%) not yet all yellowish, with spikelets at semi-hard stage and the seeds with 20 to 30% of moisture.

Mudança de concepção das políticas públicas para o campo brasileiro: o Programa de Aquisição de Alimentos, PAA

In the 90, the public politics for the Brazilian rural way incorporated the territorial perspective, besides they motivate the participation and the beneficiaries collective organization. In 2003 the Food Acquisition Program (FAP) was created with the intention of guaranteeing the feeding of people in social vulnerability situation or alimentary insecurity and of providing work and income in the field through the direct buying of the agriculturists foods. In a research made in two São Paulo State's towns: Tupi Paulista and Dracena, it was verified that the price paid to the farmers is higher to the regional average and because of this fact the participants have interest in enlarging the cultivated area and/or in diversifying the cultivations. Though, two problems were detected: 1) the reduced number of beneficiated producers; and, ii) the furtherance of the producers relatives already registered that try to increase their quota of products and the value to be received.

Caso alóctone de leishmaniose visceral canina, no município de Campo Mourão, Paraná, Brasil

This report aims to describe the first case allochthonous of visceral leishmanisasis (VL) in the municipality of Campo Mourao, Parana, Brazil, in a canine, Boxer breed, with eye and skin lesions, lymphadenomegaly and splenomegaly, attended at Veterinary Hospital at the Faculdade Integrado de Campo Mourao, after residing in the city of Campo Grande, Mato Grosso do Sul. The diagnosis of the disease was based on direct observation of amastigotes of Leishmania spp., in popliteal lymph nodes, suggesting that a case of VL, since the animal came from an endemic area for the disease. The migration of infected dogs from endemic regions to areas unaffected becomes a problem for public health, since it may allow the installation of new outbreaks by encouraging the spread of disease throughout the country.

Tabelas de esperança de vida e fertilidade para Lipaphis erysimi (Kalt.) (Hemiptera: Aphididae) em condições de laboratório e campo

In this study, the aphid Lipaphis erysimi (Kalt) was reared at different temperatures, under laboratory and field conditions, aiming to obtain age-specific life tables. In the laboratory, L. erysimi was fed on kale, Brassica oleracea L. var acephala, and kept in incubators adjusted to 10, 15, 20, 25 and 30°C, 14h photophase and 70±10% RH. The longest mean generation time (T) was observed at 15°C (23.86 days) and the shortest at 30°C (7.18 days), while the smallest net reproductive rate (R0) occurred at 15°C (4.30) and largest one at 25°C (38.29). For the temperatures of 15, 20, 25 and 30°C, the intrinsic rate of natural increase (rm) and the finite rate of increase (λ) were 0.06/1.06, 0.24/1.27, 0.28/1.33 and 0.23/1.25, respectively. The doubling time (DT) at 15, 20, 25 and 30°C were 11.55, 2.80, 2.47, and 3.01 days, respectively. Under field conditions, the net reproductive rate (R0) of L. erysimi was larger in the winter (53.50) than in the summer (40.99), the same being observed for the mean generation time (T), which was 13.85 days in the winter and 7.57 days in the summer. The intrinsic rate of natural increase (rm) and the finite rate of increase (λ) were 0.29/1.34 and 0.40/1.63 for winter and summer, respectively. The doubling time (DT) observed for winter (2.39 days) was larger than the one observed for summer (1.41 days). The temperature affects longevity of L. erysimi and the best parameters of life table of fertility under laboratory conditions are obtained at 25°C. The data obtained in field conditions reinforced this finding. The daily fecundity was higher and longevity was smaller in the summer than in the winter, thus increasing the innate capacity of increasing in number and duplicating the population in a shorter period of time.

Atividades psiquiátricas no campo dos transtornos devidos ao uso de substâncias psicoativas

There are a large number of institutions, proposals and publications in the field of disorders resulting from the use of psychoactive substances. There is no corresponding progress in results obtained in clinical treatments. Concepts and appropriate points of view are indispensable. The vision of the world drug addicts is not only determined by the biochemical effects of intoxication, but also by the experience they go through, by their own way of living. By accepting such postulate, we may conceptualize the problem, thus benefiting research studies and more efficient treatments. Preventing intoxication, upon the onset of dependence, depends on educational, social, legal and other measures, which can neither be studied nor practiced by medicine.

Precisão de plantas planialtimétricas em função do posicionamento de pontos em irradiadas de campo

The present experiment aimed to study the influence of point positioning in an irradiated field to produce a planialtimetric plant. A planialtimetric evaluation was carried out in a 14-acre experimental area with well-defined topographic variations. Planialtimetric maps were designed using manual procedures, Datageosis and Topoesalq. Datageosis built all the curves after numerical surface modeling. Topoesalq provided only height reports and the drawing of curves was done manually. The third method was a manual procedure. Because there were planialtimetry representation differences, longitudinal profiles were used in the sites where there was a great divergence among plants. When obtained profiles and plants were compared, it was verified that the one produced by Datageosis represented the relief plant better. Later, only the irradiated field points were evaluated and each point presented positioned readings before and after each relief map variation. The processing through the three methods resulted in significant plants of the local planialtimetry, according to the control profiles. It was concluded that the planning of the field procedure should be suitable to the posterior treatment method of obtained data in order to make a planialtimetric plant to accord to the evaluated local topography.

Orientação semi-automática de imagens CBERS usando rodovias como controle de campo

In this paper is proposed a methodology for semiautomatic CBERS image orientation using roads as ground control. It is based on an iterative strategy involving three steps. In the first step, an operator identifies on the image the ground control roads and supplies along them a few seed points, which could be sparsely and coarsely distributed. These seed points are used by the dynamic programming algorithm for extracting the ground control roads from the image. In the second step, it is established the correspondences between points describing the ground control roads and the corresponding ones extracted from the image. In the last step, the corresponding points are used to orient the CBERS image by using the DLT (Direct Linear Transformation). The two last steps are iterated until the convergence of the orientation process is verified. Experimental results showed that the proposed methodology was efficient with several test images. In all cases the orientation process converged. Moreover, the estimated orientation parameters allowed the registration of check roads with pixel accuracy or better.

Determinação da distribuição de um nível de turbidito na formação Macaé no campo de Namorado através de uso de atributos sísmicos

This study was developed on the basis of petrophysics characterization, 3D seismic interpretation, and rock-wire-log integration. The results were integrated with amplitude attribute through cross plot (rock attribute x amplitude value). 3D seismic data also allowed inteipreting the top of Lagoa Feia, Macaé, and Carapebus formations, and Outeiro Member. The analyses of the maps of structures and attributes, integrated with wire-log data, suggest that Namorado turbidite level is candidate to be mapped with stratigraphic attributes like AverageTroughAmplitude, RMS velocity and Total AbsoluteAmplitude. Lagoa Feia Formation attribute maps (Dip-Azimuth and TotalEnergy) allows to interpret a low fault density at the carbonate coquina level in the Namorado field. This level is also considered one at the best seismic reflector and an important reservoir of the Campos Basin.

Efeito residual de calcário, nitrogênio e zinco na produção de matéria seca de Brachiaria decumbens em condições de campo

The balance of liming and fertilization practice with nitrogen and zinc could affect the production of the pasture. Thus, the present work has as objective to evaluate the residual effect of the application of calcareous rock, nitrogen, and zinc on the dry matter production of Brachiaria decumbens, during three cuts. For this, an experiment was installed in Selvíria, Brazil, on a distrofic red Latosol, from october 1997 to may 1998. The experimental design was randomized blocks, in a factorial project 3×3×2, with four repetitions. The treatments were three doses of nitrogen: 0, 50, and 100 kg/ha, three doses of lime: 0, 267, and 556 kg/ha, corresponding to 41, 50, and 60% of the levels of base saturation, respectively, and two doses of zinc 0 and 5 kg/ha, applied in the first year and reapplied in the second year, except for the limestone. Four cuts were done in the grass at 10 cm of height, with intervals of 49 days, to obtain the dry matter production. The limestone application in the first year did not provide to residual effect on the production of Brachiaria decumbens. However, the nitrogen fertilization increased the dry matter production of the grass. The application of zinc in the first year and the reapplication in the second year did not result in a productive response of B. decumbens. © 2009 Instituto Nacional de Investigaciones Agricolas INIA.
