A escola normal de natal (Rio Grande do Norte, 1908-1971)

The research aims to analyze Professor Education in Natal, Rio Grande do Norte-Brazil in the period of 1908 to 1971. The work falls under the theme History of Scholar Institutions as well as Professor Education. The research investigates the evolution of the so called Normal School, a school that aimed professor education. It was based on assumptions by works of Chartier (1990), Chervel (1990), Elias (1994), Nóvoa (1987), Schriewer (2000), amongst others. The research dealt with a great array of documents in different institutions such as Minutes, Public Instruction Management Reports, Laws, newspaper articles (from the newspaper A Capital, A Ordem e A República), magazines such as Pedagogium (1921-1940); all of which present in the Geographical and Historical Institute of Rio Grande do Norte in Brazil. In the State´s public archive it was possible to find a book called Livro de Honra (1914-1919) as well as class diaries and books that contained details related to Scholar group Inscriptions. In the Atheneu Memorial the Atheneu Congregation of Normal School (1897) document was analyzed. In the Kennedy Superior Institute the researcher analyzed the Professor Nominal Graduation Registry Book. The work proposes a comparative study regarding the genesis present in the Lisbon Primary Normal School and the ones situated in Natal. The analysis dealt with institutional meanings attributed by educators. Documents from The Portuguese National Library as well as the Lisbon Superior Education School were analyzed. In this in environment, it was possible to analyze documents such as Minutes, Books, Manuals, Internal Regiments related to Pedagogy. The study allowed acknowledging that these Normal Schools emerged from the same historical substrate and present consonance between the two countries regarding once both were associated with politicians, professors, doctors, hygienists and professionals evolved with education. It was also possible to acknowledge that there is a presence of a pedagogical discourse attached to the primary school universe and professor education. The Natal Normal School was present in different contexts and was consolidated as an institution that was responsible for the education and preparation of primary school teachers. The school was considered a locus where it was possible to produce and work with specific knowledge in a peculiar fashion. This knowledge provided the necessary support for professor education and was in accordance with the world´s professional pedagogical movement as well as ideas, discussions and reflections. This school was considered a space for pedagogical activities, professional affirmation allowing action reflection enabling professor representation as knowledge producers legitimating professor instruction

O livro de leitura da campanha de pé no chão também se aprende a ler/RN: um estudo dos pressupostos histórico-culturais

This work is about the historical and cultural assumptions inserted in the contents of literacy of the Campanha de Pé no Chão Também se Aprende a Ler, a movement of culture and popular education, developed in the State of Rio Grande do Norte in the period between 1961 and 1964. The hypothesis is the one of the existence of a romantic-political ideology which permeated a national developmentalist conception sited in its didactic-pedagogic instrument of literacy, the Book of Lecture of De Pé no Chão Também se Aprende a Ler/RN (1963). It has the aim to understand how the popular critical consciousness marked by conceptions of culture and popular education in its social, cultural and ideological relations, happened. Analyses the object of study by the symbolical cartography, methodological procedures which have as principles to retire from an antecedent source implicit meanings that can discover new realities, articulating the keywords of that document to the ideology that surrounded the Campanha de Pé no Chão Também se Aprende a Ler /RN. As results, the research showed that, considering the historical-cultural assumptions of the national developmentalist thought sited in the studied Book of Lecture, the conditions of the political-cultural context and of the advance of the Brazilian national industry on the beginning of the 1960th , admitted a process of social integration lavished by the popular literacy on the Campanha de Pé no Chão/RN, linked with the possibility of transition of the popular conscience, in a romantic-political perspective of the culture and the popular education

Estudo do sistema portal hepático no pato doméstico (Cairina moshata)

Estudou-se o comportamento do sistema portal hepático em 30 patos domésticos, adultos, machos e fêmeas. O sistema apresenta-se constituído por duas veias portais hepáticas: direita e esquerda. A veia portal hepática esquerda é formada por veias gástricas esquerdas (em número de 1 a 2), veias da margem ventral do ventrículo, veia pilórica e veia proventricular caudal. A veia portal hepática direita é formada pela veia mesentérica caudal, veia mesentérica cranial, veia proventrículo-esplênica e veia gastropancreaticoduodenal. A veia mesentérica caudal recebe tributárias do mesorreto, cloaca e junção ileocecocólica. A veia mesentérica cranial recebe tributárias jejunais (em número de 12 a 21) e se anastomosa com a veia mesentérica caudal, formando a veia mesentérica comum. A veia pancreaticoduodenal recebe duas veias gástricas direitas, constituindo assim a veia gastropancreaticoduodenal. A veia proventrículo-esplênica é formada pelas veias proventriculares dorsal e direita e pelas veias esplênicas.

The Developing Left Superior Cervical Ganglion of Pacas (Agouti Paca)

In this study the main question investigated was the number and size of both binucleate and mononucleate superior cervical ganglion (SCG) neurons and, whether post-natal development would affect these parameters. Twenty left SCGs from 20 male pacas were used. Four different ages were investigated, that is newborn (4 days), young (45 days), adult (2 years), and aged animals (7 years). By using design-based stereo-logical methods, that is the Cavalieri principle and a physical disector combined with serial sectioning, the total volume of ganglion and total number of mononucleate and binucleate neurons were estimated. Furthermore, the mean perikaryal (somal) volume of mononucleate and binucleate neurons was estimated using the vertical nucleator. The main findings of this study were a 154% increase in the SCG volume, a 95% increase in the total number of mononucleate SCG neurons and a 50% increase in the total volume of SCG neurons. In conclusion, apart from neuron number, different adaptive mechanisms may coexist in the autonomic nervous system to guarantee a functional homeostasis during ageing, which is not always associated with neuron losses.

PREVALENCE of SALMONELLA SPP. ANTIBODIES TO TOXOPLASMA GONDII, and NEWCASTLE DISEASE VIRUS IN FERAL PIGEONS (COLUMBA LIVIA) IN THE CITY of JABOTICABAL, BRAZIL

The rock pigeon (Columba livia) may serve as a reservoir for several pathogenic agents that can be transmitted to poultry, wildlife, domesticated pets, and/or humans via excreta, secretions, or dust from feathers. In addition, ingestion of infected pigeons by wild and domestic animals can also transmit these pathogenic agents. The health status of 126 free-living pigeons in an urban area was evaluated by microbiologic culture for Salmonella and serologic testing for the presence of antibodies for Toxoplasma gondii and for Newcastle disease virus (NDV) from 120 and 109 pigeons, respectively. After drawing blood, the birds were euthanized, and fragments of the liver, spleen, lungs, and gonads, and feces were cultured for Salmonella spp. Salmonella spp. was isolated from 10 birds (7.94%), of which 8 were Salmonella typhimurium, one was Salmonella enterica subsp. enterica serotype 4,12 and one was Salmonella enterica subsp. enterica serotype 4,12,i. Six of 109 pigeons (5.50%) were positive for NDV antibodies when using the hemagglutination inhibition test. Toxoplasma gondii antibodies were detected by immunofluorescence in one of 120 sera tested (0.83%). The results indicate that feral rock pigeons were exposed to NDV and T gondii, although the exposure was low. In addition, these birds had Salmonella spp. and could disseminate this pathogen in the environment.

Immunohistochemical characterization of mononuclear cells and MHC II expression in the brain of horses with experimental chronic Trypanosoma evansi infection

Este estudo objetivou caracterizar a resposta imune celular no sistema nervoso central (SNC) de eqüinos com infecção crônica experimental por Trypanosoma evansi. Para este propósito, foram utilizados os métodos histoquímicos (HE) e imunoistoquímicos do complexo avidina-biotina peroxidase (ABC). O fenótipo do infiltrado celular foi caracterizado com o auxílio de anticorpos anti - CD3, para linfócitos T e antiBLA36 para linfócitos B. Os macrófagos foram marcados com anticorpo antiantígenos da linhagem mielóide/histiócitos (Clone Mac387). A lesão no sistema nervoso central (SNC) dos eqüinos infectados com T. evansi foi caracterizada como meningoencefalite e meningomielite não supurativa. A gravidade das lesões variou em diferentes segmentos do SNC, refletindo distribuição irregular das alterações vasculares. A distribuição de células T e B e antígenos do complexo maior de histocompatibilidade classe II foram avaliados dentro do SNC de eqüinos cronicamente infectados com T. evansi. O infiltrado perivascular e meníngeo eram constituídos predominantemente por células T e B. Macrófagos foram raramente visualizados. T.evansi não foi identificado no parênquima do SNC dos eqüinos.

Soroprevalência da infecção por Trypanosoma cruzi em cães de uma área rural do Estado de Mato Grosso do Sul

Doença de Chagas é uma antropozoonose causada por Trypanosoma cruzi que tem os cães como importante reservatório da doença na América do Sul. Este trabalho teve como objetivo avaliar a ocorrência da infecção natural pelo T. cruzi em cães de uma área rural do estado de Mato Grosso do Sul, Brasil. Foram utilizados os testes de imunofluorescência indireta (IFI) e ensaio imunossorvente ligado a enzima (ELISA) em 75 cães residentes na área. Foram detectados anticorpos em 45,3% (n=34) e 24,0% (n=18) nos testes de IFI e ELISA, respectivamente. A real prevalência da infecção foi confirmada como 22,7% (n=17) pelo critério de positividade em ambos os testes. Os resultados obtidos confirmam a infecção chagásica nos cães dessa região.

Consorciação e plantas daninhas afetando a produtividade e a qualidade de sementes de sorgo

This research aimed to study competition effects of legumes intercropping and weeds on seeds yield and quality of Sorghum bicolor (L.) Moench. The experiment was carried out in a Rhodic Nitisol, under field condition in Botucatu region, São Paulo State, Brazil. Ten treatments were tested: sorghum (cv. A-6304) intercropped with Dolichos lablab L., Mucuna aterrima (Piper et Tracy) Holland, Canavalia ensiformis D. C. or Crotalaria juncea L., that were sown in the same time of sorghum or 20 days after the sorghum sowing, and sorghum weed-free and sorghum without weeding. The experimental design employed was the completely randomized blocks with four replications. There were evaluated sorghum seeds yield and some characteristcs of seed quality: purity, hectolitric weight, 1000 seeds weight, insect infestation, germination and vigor (by first counting of germination test and accelerated ageing test). The competition caused by legumes intercropping and weeds affected the yield and the physical and physiological characteristics of sorghum seeds, but the intensity of prejudicial effects depended on the time and the species of legume intercropping.
