Abstract: OBJETIVO: avaliar de forma subjetiva e objetiva a voz de pacientes com paralisia unilateral de prega vocal nos momentos pré-tratamento e pós-tratamento. MéTODOS: trata-se de um estudo retrospectivo por meio de revis o de prontuário, que analisou as grava es de vozes de 12 indivíduos com diagnóstico otorrinolaringológico de paralisia unilateral de prega vocal. O material de voz colhido foi a emiss o sustentada da vogal /a/, seguida de fala encadeada. As vozes pré e pós-terapia foram analisadas por meio da escala GRBASI, análise espectrográfica e medida do tempo máximo de fona o (TMF). Os parametros para análise espectrográfica foram: forma do tra ado, grau de escurecimento dos harm nicos, continuidade do tra ado, presen a de ruídos, presen a de sub-harm nicos e harm nicos definidos. A medida do TMF da vogal /a/ representou a maior de três emiss es. Os dados obtidos foram submetidos a análise descritiva de tendência central e dispers o, e ao Teste Wilcoxon. RESULTADOS: na análise perceptivo-auditiva, o parametro que mais se modificou no momento pós- tratamento foi o de soprosidade (B) (p=0,003), seguido do grau da disfonia (G) (p=0,004) e astenia (A) (p=0,01), sendo que estes resultados foram estatisticamente significantes. Com rela o ao espectrograma, houve melhora do tra ado em 91% dos pacientes, e os parametros que mais se modificaram foram: aumento do número de harm nicos (32%) e diminui o do ruído (24%). A medida do TMF da vogal /a/ apresentou-se significantemente maior no momento pós-fonoterapia (p=0,003%). CONCLUS O: pacientes com paralisia de prega vocal que foram submetidos ao tratamento fonoaudiológico apresentaram melhora dos dados perceptivo-auditivos, espectrográfico e do TMF.

Abstract: the diagrammatic scales are important tools to standardize the severity assessments of plant diseases. the objective of this work was to develop and to validate a diagrammatic scale for severity assessment of leaves spot phaeosphaeria on maize. the proposed scale had the levels of 1; 3; 6; 13, 25; 43; 63 and 79% of severity in the third medium part of the maize leaf. scale validation was performed by ten raters (five inexperienced and five experienced), who estimated the severity disease in 50 maize leafs showing phaeosphaeria leaf spot symptoms, with and without the use of the scale. analyses of regression was used to evaluate the precision and accuracy of the estimates. the evaluation of the accuracy indicated that without the use of the scale seven raters had presented systematic shunting lines in the estimates, whereas with the use of the scale they was only two raters. the precision represented for coefficient of determination (r2 ) of the regressions, varied of 0.86 the 0.95 for the inexperienced raters without scale and 0.91 the 0.98 with scale. the proposal diagrammatic scale improved the precision and accuracy of the estimates, independent of the experience of the raters.

Abstract: Castor oil polymer is a biomaterial that can be used to fill bone defects. Biomaterials should present some characteristics such as: biocompatibility, inert, absence of toxin radical and vapour discharge and permit the organism to recognize them as a part of their structure. The aim of this study was to investigate changes in water ingestion, feed intake, weight gain and toxic effects in rats (Rattus norvegicus) after ingestion of 0, 10, 25 and 50% of castor oil polymer (COP, Ricinus communis). In groups that received 10 and 25% of COP the weight gain was smaller than the control group. Feed intake in control group was greater than in groups 10 and 50% COP. The intake of castor oil polymer reduced feed intake and water ingest probably because of the palatability of the product. In the second part of this study (multigenerational) there were no toxic effects in the offspring, as external birth defects or alterations incompatible with life, in spite of the fact that lower weight were observed in males and females of the second generation. KEY WORDS: Biomaterials, bone defects, polymer, Ricinus communis. Os biomateriais s o polímeros artificiais desenvolvidos para substituir tecidos organicos danificados e preencherem falhas ósseas. Eles devem apresentar características como a biocompatibilidade, serem inertes, n o liberarem vapores e radicais tóxicos e permitirem ao organismo reconhecê-los como parte de sua estrutura. Procurou-se determinar a ingest o de água, o consumo de ra o, ganho de peso e possível efeito tóxico decorrentes da ingest o de três doses (10%, 25% e 50%) do derivado do polímero de mamona (PM, Ricinus communis), adicionado à água de bebida, em ratos (Rattus norvegicus). Nos grupos que receberam 10% e 25% do PM, o ganho de peso foi menor (P?0,05), quando comparado ao grupo-controle. O consumo de ra o nos grupos que receberam 10% e 50% de PM foi menor em rela o ao grupo-controle. A ingest o do polímero de mamona reduziu a ingest o de ra o e o ganho de peso, provavelmente relacionado à palatabilidade do produto. Numa segunda fase experimental (estudo multigeracional) n o se verificaram efeitos tóxicos, nas proles, como má forma o externa e altera es incompatíveis com a vida, apesar de ter havido redu o no peso dos machos e das fêmeas da segunda gera o. PALAVRAS-CHAVES: Biomateriais, falhas ósseas, polímeros, Ricinus communis.

Abstract: OBJETIVO: Analisar uma nova técnica de isolamento das células do tumor de Walker, utilizando o gradiente de ficoll-hypaque. MéTODOS: Vinte ratos Wistar machos foram divididos em 2 grupos (G1, G2). O tumor do animal doador foi dissecado, triturado em solu o de ringer lactato e filtrado. A suspens o celular obtida foi dividida em duas alíquotas (A1 e A2) e a alíquota A2 foi centrifugada em gradiente de ficoll-hypaque. As duas alíquotas foram ajustadas para uma concentra o de 1X10(6) células/ml. Um ml da suspens o A1 ou A2 foi injetado por via subcutanea na axila direita dos ratos dos seus respectivos grupos. Os diametros tumorais, peso tumoral e análise histológica foram avaliados. RESULTADOS: N o houve diferen a no volume tumoral (G1=17,9?3,8cm3; G2=17,2?4,4cm3; p=0,190) e no peso tumoral (G1=7,0?1,8g; G2=7,3?2,8g; p=0,569). A análise histológica evidenciou padr es semelhantes de infiltra o de células pequenas indiferenciadas e de necrose nos dois grupos. Entretanto, exsudato granulocítico leve a moderado foi mais acentuado no G2 do que no grupo G1 e hemorragia leve a moderada foi observada somente no grupo com ficoll. CONCLUS O: O gradiente de ficoll-hypaque é uma técnica adequada de isolamento das células do tumor de Walker e fornece uma suspens o celular menos contaminada com outros tipos celulares.
