"Educação e saúde: reflexões sobre a arte do dialogo amoroso entre enfermos e homeopatas"

Esta dissertação analisa a relação existente entre o modelo médico dominante na sociedade moderna e o surgimento contra-hegemônico de outras racionalidades médicas alternativas. Tento mostrar como estes outros modelos médicos têm a intenção de superar o reducionismo biomédico, através do desenvolvimento de processos terapêuticos alternativos, que se têm convertido em novas soluções para o “complexo-sofrente” que constitui o ser humano. Inclui uma reflexão crítica que em uma pesquisa realizada do final de 90 a meados de 91, colheu depoimentos em entrevistas com profissionais homeopatas e pacientes do serviço de Homeopatia do CSECSF, da ENSP/FIOCRUZ (Centro de Saúde-Escola Germano Sinval Faria, Escola/Nacional de Saúde Pública, Fundação Oswaldo Cruz). Procurou-se enfatizar a questão da Educação e Saúde, como geratriz de transformações conceituais e vivenciais: a saúde, a doença, a cura e a relação médico-paciente. Assim como, dar destaque à ação “educativa” específica de fazer homeopático – o processo de “singularização” (“não há doenças e sim, doentes”), que envolve os atores sociais do ato médico homeopático.

Efeito do protocolo de exercício sobre variáveis hematológicas e bioquímicas em eqüinos de salto

O presente estudo teve por objetivo avaliar as variações provocadas por diferentes protocolos de atividade física nos parâmetros hemato-bioquímicos de eqüinos de salto. Foram utilizados dezessete eqüinos atletas, de raças de hipismo, com idades variando entre 5 e 12 anos. Todos os animais fizeram parte de três grupos de exercício e um de repouso. Foram realizadas coletas de sangue venoso e verificação da freqüência cardíaca com os animais em repouso (grupo Controle) e imediatamente após a realização de três diferentes protocolos de exercício. Os animais foram submetidos a 20 e 40 minutos de exercício em esteira com inclinação de 0o a velocidade constante de 5 m/s (grupo Esteira), 40 minutos de trabalho montado sendo 10 minutos ao passo, 20 minutos de trote e 10 minutos de galope em pista plana de areia (grupo treinamento) e prova de salto à velocidade média de 350 m/min, altura dos obstáculos de 1,20 metros e extensão do percurso de 430 metros (grupo Prova). Os parâmetros hematológicos (número de eritrócitos, concentração de hemoglobina e contagem leucocitária), a freqüência cardíaca, dosagem das enzimas creatina quinase (CK), aspartato aminotransferase (AST), lactato desidrogenase (LDH) e fosfatase alcalina (FA), dosagem de sódio e potássio, bicarbonato, proteínas plasmáticas totais, uréia e creatinina foram analisados. Os valores obtidos foram comparados com os valores basais e entre os grupos de exercício. O exercício em Esteira provocou aumento significativo no percentual de hematócrito e concentração de creatinina. A concentração de glicose apresentou redução após 20 e 40 minutos de exercício. O grupo Treinamento revelou aumento no número de eritrócitos, aumento de hematócrito, proteínas totais, CK, LDH, FA, creatinina, potássio e redução nas concentrações de glicose. O grupo Prova apresentou contagem de eritrócitos superior aos demais grupos, assim como percentual de hematócrito, concentração de hemoglobina e proteínas plasmáticas totais. Nesse grupo, as dosagens de CK, LDH, FA, lactato, creatinina e potássio apresentaram valores significativamente superiores em relação ao grupo Controle. A freqüência cardíaca revelou aumento significativo após a realização da atividade física quando comparados com o grupo Controle e entre os grupos. As variações encontradas foram de amplitude maior no grupo Prova. O aumento da intensidade do exercício físico provoca alterações em alguns parâmetros hemato-bioquímicas em cavalos de salto. A contagem eritrocitária, o percentual de hematócrito, a concentração de proteínas plasmáticas, lactato, potássio, creatinina, CK e FA elevam-se com o aumento da intensidade do exercício. A contagem leucocitária, dosagem de AST, sódio, bicarbonato e uréia não sofreram influência da intensidade de exercício proposta nos protocolos. A concentração de glicose é reduzida pelo exercício desempenhado nos grupos treinamento e prova.

Detecção de Bordetella bronchiseptica a partir de suabes nasais de suínos pela bacteriologia clássica e pela reação em cadeia pela polimerase

A Bordetella bronchiseptica é um dos agentes etiológicos da rinite atrófica e de pneumonia em suínos. Embora os prejuízos econômicos gerados por esses distúrbios respiratórios sejam amplamente reconhecidos, o impacto desse patógeno na sanidade dos rebanhos é freqüentemente subestimado. Isso se deve, em parte, à dificuldade de isolar a Bordetella bronchiseptica a partir dos espécimes clínicos que em muitos casos está presente em pequeno número na cavidade nasal. Este trabalho descreve a determinação do meio de transporte mais adequado, às nossas condições, que favoreçam sua detecção da Bordetella bronchiseptica e a comparação de três meios seletivos para o seu isolamento. Também foram comparadas as sensibilidades dos meios de isolamento e da técnica de reação em cadeia pela polimerase. O meio de transporte que apresentou melhor desempenho, avaliando as temperaturas testadas (10ºC e 27ºC) em conjunto, foi o meio Amies com carvão. De acordo com os resultados obtidos e a praticidade de seu uso na rotina clínica, a temperatura de 27ºC foi a eleita para o transporte dos espécimes. Os três meios seletivos empregados para o isolamento primário de Bordetella bronchiseptica a partir de suabes nasais mostraram semelhantes capacidades de recuperação da bactéria, mas o ágar MacConkey selecionou melhor os espécimes colhidos, recuperando um número maior de colônias. Mesmo usando o meio e a temperatura de transporte mais favoráveis para o transporte de suabes nasais e o meio seletivo mais sensível determinado neste estudo, a reação em cadeia pela polimerase apresentou uma capacidade de detecção da Bordetella bronchiseptica superior a do cultivo.

Purificação e caracterização parcial de uma Fucana C de Dictyota mentrualis e estudo do seu efeito antiinflamatório e nociceptivo

In recent years, sulfated polysaccharides from marine algae have emerged as an important class of natural biopolymers with potential application in human and veterinary health care, while taking advantage of the absence of potential risk of contamination by animal viruses. Among these, fucans isolated from the cell walls of marine brown alga have been study due to their anticoagulant, antithrombotic, anti-inflammatory and antiviral activities. These biological effects of fucans have been found to depend on the degree of sulfation and molecular size of the polysaccharide chains. In the present study, we examined structural features of a fucan extracted from brown alga Dictyota menstrualis and its effect on the leukocyte migration to the peritoneum. The sulfated polysaccharides were extracted from the brown seaweed by proteolytic digestion, followed by sequential acetone precipitation producing 5 fractions. Gel lectrophoresis using 0.05 M 1,3-diaminopropane-acetate buffer, pH 9.0, stained with 0.1% toluidine blue, showed the presence of sulfated polysaccharides in all fractions. The chemical analyses demonstrated that all fractions are composed mainly of fucose, xylose, galactose, uronic acid, and sulfate. Electrophoresis in agarose gel in three different buffers demonstrated that the fraction 2.0v have only one population of fucan. This compound was purify by exclusion molecular. It has shown composition of fucose, xilose, sulfate and uronic acid in molar ration of 1.0: 1.7: 1.1: 0.5 respectively. The effect of this heterofucan on the leukocyte migration was observed 6h after zymozan (mg/g) administration into the peritoneum. The heterofucan showed higher antimigratory activity, it decrease the migration of leukocyte in 83.77% to peritoneum. The results suggest that this fucan is a new antimigratory compound with potential pharmacological appications

Ocorrência e tratamento de monogenoides em alevinos de pampo (Trachinotus carolinus) cultivados experimentalmente na região norte do estado de São Paulo

This work had as objective tests therapeutic treatments seeking the monogenea eradication in fingerlings Florida Pompano (Trachinotus carolinus) servants in cage net in the area of Ubatuba, State of São Paulo. The fingerlings presented an accentuated weigh loss and strong discoloration and through observation of scraped of gills under light microscope were identified a high amount of monogenea. Three treatments were tested in form of baths: T1 (fresh water for 5 minutes); T2 (formalin: 1: 1.000 for 20 minutes) and T3: (formalin: 1:4.000 for 30 minutes). The treatments were appraised through scraped of gills, mounted among you laminate and laminulas and observed to the light microscope. It was observed that in the tested conditions all of the treatments were efficient in the elimination of the monogenea without presenting lethality to the fish. The treatment is recommended T I (take a bath in fresh water for 5 minutes) for the facility in the application and for the absence of use of chemical products.

Metacromasia para identificação de basófilos sanguíneos em surubim híbrido: contribuição metodológica

Padua S.B. & Ishikawa M.M. [Metachromasia for blood basophils identification in hybrid surubim catfish: methodological contribution]. Metacromasia para identificacao de basofilos sanguineos em surubim hibrido: contribuicao metodologica. Revista Brasileira de Medicina Veterinaria, 33(3):147-150, 2011. Centro de Aquicultura da Unesp/Jaboticabal Rod. Paulo Donato Castellane, s/n Bairro Rural, Jaboticabal, 14884-900, SP. Brasil. E-mail: santiagopadua@live.comDifferent protocols of fixation and hydrolysis of blood smears of hybrid surubim catfish for metachromasia to marking blood basophils were evaluated. For this reason, methanol, acid-alcohol and formalin vapor were tested as fixatives. For hydrolysis of blood smears, HCl, citric acid and 2-Mercaptoethanol + Urea + NaCl solutions was evaluated. After procedures, the blood smears was stained with toluidine blue (0.025%) diluted in McIlvaine buffer (pH 4). The different protocols for fixation and hydrolysis of blood smears for metachromasia influenced the quality of the reaction. Hydrolysis with 2-Mercaptoethanol + Urea + NaCl solutions provided negative results when using methanol and acid-alcohol as fixatives. The fixation with acid-alcohol associated with citric acid hydrolysis provides highest quality reason.

Identificação morfológica de organismos semelhantes à anaplasmataceae em monócitos de surubim híbrido (Pseudoplatystoma reticulatum x P. corruscans) – relato de caso

The aim of this study was to report the occurrence of Anaplasmataceae-like organisms in monocytes from the hybrid surubim catfish. During the hematological evaluation of fish infected by Pseudomonas sp. in a fish farm located in the State of Mato Grosso do Sul we observed into the monocytes the presence of numerous pleomorphic inclusions of various sizes, rough in appearance which presented basophilic staining. These inclusions were similar to elementary bodies, initial bodies and morule of the bacteria from Anaplasmataceae family, often diagnosed in domestic mammals. This is the first report of its occurrence possibly belonging to the family of Anaplasmataceae in cultured fish in Brazil. Additional studies are necessary for molecular characterization of this bacteria, pathogenic potential, life cycle and impact on the intensive production of fish.

Tecido hepático e corpo adiposo de rã-touro (Lithobates catesbeianus) submetido a diferentes fotoperíodos

The study was conducted to evaluate the liver tissue weight, body fat weight, the fatty somatic index and the liver somatic index of bullfrogs subjected to three photoperiod during the growing phase (initial 30 days) and finishing (60 days). The treatments were 16 h light and 8 h dark, 12 h of light and dark and 8 h light and 16 h dark. The experimental design was completely randomized design with three replications. We used 36 bullfrogs/m2 weighing from 22 to 28 g. The results were submitted to ANOVA and Tukey Test at 5% probability. Differences were found for the weight of body fat, liver tissue weight, liver somatic index and fatty somatic index the bullfrog to the treatments and the study periods and there is greater accumulation of energy to ninety days. The photoperiod did not influence body weight and fat weight of the liver tissue of bullfrog at the end of the fattening period and the difference fatty somatic index and liver somatic index were influenced by body weight of animals.

Determinação de parâmetros de qualidade para formas farmacêuticas homeopáticas

All medicine, whether allopathic or homeopathic, must go through strict quality control, which must ratify their characteristics throughout the period of validity. During the time of preparation and storage, solutions of the drugs are in permanent contact with packaging materials that can release undesirable substances to the solution. Several factors may influence the release of packing materials, and factorial design (FD) is a useful tool for analyzing the phenomenon. The aim of this study was the determination of quality parameters for Homeopathic solid (globules) and liquid (drops) dosage forms. It was carried out analysis in homeopathic globules for weight variation, mechanical strength, and moisture content uniformity. For liquid preparations, standard solutions were prepared from natural rubber bulbs, which were subjected to exhaustive extraction with two ethanol solutions (30 and 70%) in the ultrasonic bath for 20 minutes at 25°C and 50°C in three successive cycles. Studies of transfer have been made within five days, by spectrophotometric analysis in the UV region at 312 nm with λmáx and 323 nm for samples in 70% ethanol and 30% respectively. PH values were analyzed. We also conducted two FD studies, where the first, the three-level variables were solvent (chloroform, ethanol and nhexane), sample mass (30, 60 and 90mg), particle size (large disk, small disk and powder sample). In the second study, the solvent level variables were different ethanolic degrees (EtOH 30%, 70% and pure). The percentage of lending in the solutions was 5.5%, 12.4%, 24.2% and 41% of the total estimated in the reference solution. The values of rate constants of transfer were determined in the order of 0.0134 days-1 and 0.0232 days-1 in absorbance values, the solutions in ethanol at 30% and 70% respectively. These results suggest that the speed of transfer of materials from rubber is affected both by the nature of the vehicle as by the temperature

Avaliação in vitro da eficácia de produtos homeopáticos contendo momordica charantia através de bioensaios

Homeopathic medicines have been used for over two hundred years without the examination of their effects on in vivo and in vitro assays, due to the peculiarity of homeopathic preparations, the high dilution, which creates a challenge for the use of usual analytical techniques of quality control of medicine.Although there is scarcity of literature and variety of experiments, recently there have been some studies with few in vitro assays which have shown positive responses when evaluating the mechanism of action of homeopathic medicines which are able to act on a specific system.The present study aims to evaluate the efficacy of homeopathic products containing Momordica charantia through bioassays.Homeopathic products were tested by the MTT to assess cytotoxicity in RAW 264.7 (macrophage-like cells) and in tumor cells HeLa (human cervical adenocarcinoma cells), CHO K1 (Chinese hamster ovary cells), PANC-1 (human pancreas cancer cells) and PC-3 (human prostate cancer cells), dosage of inflammatory mediators NO, TNF-α and IL-6 released by RAW 264.7 cells, analysis of the death process and cell cycle changes of PC-3 by flow cytometry. The data demonstrate that homeopathic products of Momordica charantia did not show cytotoxicity to RAW 264.7, increased the production of inflammatory mediators by RAW 264.7 synergistically with LPS, showed cytotoxicity to PC-3 with change in its cell cycle inhibiting its proliferation, being the 30CH the most potent sample. Correlation studies were conducted in order to evaluate the possible in vitro applicable models to the quality control of homeopathic products with Momordica charantia. The data showed that the best applicable models in assessing the quality are the MTT to assess cytotoxicity in RAW 264.7 and PC-3 in 24 hours for Momordica charantia fruit products and dosage of NO production by RAW 264.7 with and without LPS

Influence of the season of year, stage of lactation and milking time on the chloride content in bovine milk

From January to October 1995, chloride content determinations were accomplished in 2,218 samples of milk collected from 67 quarters of 17 lactating cows, in initial, middle and final stages of lactation, in the morning and afternoon milking. The highest means of chloride contents were observed among the milk samples collected in the final stage of lactation (0,203 gC1/100ml), in the summer (0,212 gC1/100ml) and in the morning milking (0,189 g C1/100ml). The differences observed between the chloride contents in the samples obtained in the different stages of lactation and the seasons of the year were statistically significant (P<0.0001). The gratest occornce of chloride at rates superior to 0.22 gC1100ml was observed in the final stge of lactation (31.4%), summer (44.2%) and after the morning milking (27.8%). These results evidentiate the influence of physiological and external factors (stage of lactation and season of the year) on the concentration of chloride of milk.

Parâmetros eletrocardiográficos e valores séricos e urinários de sódio e potássio em cães tratados com furosemida

The serum and urine Na+ and K+ levels and their relationship with electrocardiography characteristics,were studied in 15 male adult mongrel dogs, treated twice-a-day,with 2, 4, 8mg/kg of live weight doses of furosemide and furosemide associated with KCl during 35 days. Urine samples were analyzed weekly in order to determine the Na+ and K+ concentrations and to evaluate the urinary excretion of both cations. Electrocardiography was performed simultaneously, using limb derivations, speed 50mm/sec and calibration of 1 cm corresponding to 1mV. Data showed decreased seric concentrations of Na+ and Ki, increase in Na+ fractional excretion between days 7 and 21 of the treatment, slower heart rate and longer PR, QRS and QT intervals in the ECG. Briefly 2mg/kg furosemide associated with KCl was the most suitable treatment since it induced lesser side effects.
