Distribuição e abundância de larvas de Simulium spp.em córregos do estado de São Paulo nos diferentes níveis de qualidade da água

The aim of this work was to determine the distribution and abundance the species of Simulium: in 5 streams of the north coastal region of the state of São Paulo. Simulium larval and water samples were collected every 2 weeks in summer and winter, 2001. The larval were collected on artificial substrates (triplicate) preserved in alcohol (70%) and after analyzed quantitative and qualitative. From the streams the values of temperature, dissolved oxygen, conductivity, pH and stream discharge were measured. The contents of total nitrogen and dissolved nitrogen, ammoniacal nitrogen, nitrate, nitrite, orthophosphate, dissolved phosphorus and total phosphorus were determined in the laboratory. Water quality has great influence in the distribution and abundance of the species. S. pertinax was more abundant in streams without or with low levels of pollution, S. inaequale in streams more polluted and S. incrustatum in intermediary levels of pollution. S. pertinax was the species more abundant with 57.5% of presence in the samples, the second more abundant was S. inaequale with 42.1% of presence and S. incrustatum was rare with 0.4% of presence. The larval abundance was lower in the polluted environment. © 2012 by Unisinos.

Anthropometric aspects of body seated in school

This study aimed to assess the student-furniture interface from anthropometric parameters of the sitting posture. The sample was composed of 887 students from two public schools in the State of Parana - Brazil, which attended children from 7 to 17 years of age. The data collection used anthropometric measures of the sitting position, a questionnaire containing a human body diagram for indication of discomfort areas and photographic records to verify postural and ergonomic inadequacies in classroom. The following anthropometric variables were measured: popliteal height, sacro-popliteal length, hip width, lumbar support height, and elbow and thigh height. Percentiles 5 and 95 of anthropometric variables showed differences statistically significant, with variation coefficient greater than 30%. In relation to body discomfort, the highest occurrences were recorded for ankle, knees and shoulder joints as well as for spine and buttocks. It was concluded that children use school furniture that does not meet their anthropometric standards, which favored the adoption of incorrect postures and contributed to the emergence of musculoskeletal problems that can interfere with their educational process.

Perceptual aspects of the use of faucets (taps)

This paper presents an assessment with simulated activities with the aim of analyzing the perception of ease/difficulty of the use of faucets (taps) handles by 180 Brazilian adults. Five different handles faucets were activated for subsequent collection of perceptual data. The procedures were based on main recommendations for biomedical ethics and human research. The results indicate that handles with levers are significantly (p <= 0.05) easier to use. The most difficult are characterized by not having support points for the rotation (levers) or more points of pressure concentration in the hand.

Sensory aspects of liquid smoking of giant river prawn: comparison with traditional smoking

P>The purpose of this paper is to investigate the impact of liquid smoke on the sensory characteristics of giant river prawn (Macrobrachium rosenbergii). The sensorial profile was plotted using quantitative descriptive analysis and assessment of the acceptability of samples of beheaded and peeled and only beheaded freshwater prawns smoked using the traditional method or liquid smoke (LS). The prawns subjected to LS were characterised by their aroma, artificial flavour and bitter flavour. The beheaded, peeled prawns were found to be more acceptable, confirming that the presence of the shell is a limiting factor in the acceptability of smoked prawns.

Hematological, biochemical and anatomopathological aspects of the experimental infection with Trypanosoma evansi in dogs

O presente estudo acompanhou durante 82 dias o curso da infecção experimental com T. evansi em quatro cães, realizando a avaliação dos achados hematológicos, bioquímicos e anatomopatológicos. Os animais infectados mostraram declínio acentuado na contagem de hemácias, hematócrito e teor de hemoglobina, permanecendo anêmicos a partir da terceira semana de infecção até o final do período experimental. Leucopenia com neutropenia foram observadas entre a segunda e a quinta semanas após a infecção. Os cães inoculados desenvolveram hiperproteinemia, sendo constatada diminuição na relação albumina:globulina. As atividades séricas de alamina aminotransferase e aspartato aminotransferase aumentaram significativamente nos cães infectados em relação aos animais controle. O exame histopatológico revelou hiperplasia linfóide no baço e linfonodos e infiltrado mononuclear periportal e esteatose de padrão centrolobular no fígado de todos os cães infectados. Intenso infiltrado mononuclear foi observado no miocárdio de três cães e acúmulos de células mononucleares junto às meninges foram evidenciados em dois animais infectados.

Antartica 788, Casa 26, Residencial Villas Boas, Ribeirao da Ponte, Cuiaba, MT 78040-500. Brasil. E-mail: redoria@uol.com.brThe development of intracapsullar masses at the dorsal aspect of the metacarpofalangeal joint for a period of several months is commonly secondary to the chronic synovitis. Although it is known as villonodular synovitis in horses probably is better to refer it as chronic proliferative synovitis. The most common causes are the non-treated osteocondral fractures of the dorsal portion of the proximal phalanx. In addition, the development of villonodular masses follows the degenerative process in the joint. A case of a lame animal is reported at the present study. The correct diagnosis and the adequate therapeutic propositions were given based on the clinical examination, therapeutic local-anesthetic test and radioghaphic and ultrasonographic imaging exams. The development of a criterious identification of this disease must be based on clinical findings, radiographic and ultrasonographic exams which assume fundamental importance to the treatment and prognostic. The aim of this study is to describe the clinical, radiographic and ultrasonographic findings' allowing the identification and diagnosis of chronic proliferative synovitis at the thoracic metacarpofalangeal joint in the horse.

Biological aspects of the immature stages of Ceraeochrysa everes (Banks) (Neuroptera: Chrysopidae)

Para o estabelecimento de um programa de controle biológico, o conhecimento de alguns aspectos biológicos e de comportamento dos inimigos naturais é de extrema importância. Os aspectos biológicos do desenvolvimento larval e pupal do predador Ceraeochrysa everes (Banks) foram estudados. Larvas oriundas de adultos da geração F1 foram mantidas em laboratório a 25 ± 21°C, 70 ± 10 % UR e fotofase 14 horas, sendo alimentadas com ovos de Sitotroga cerealella (Olivier). A duração e viabilidade do período embrionário, estágios imaturos de desenvolvimento e o período de ovo a adulto foram avaliados. O período embrionário foi em média de 5,0 dias, enquanto que as durações médias para o primeiro, segundo e terceiro instares foram de 5,1 ± 0,03; 4,3 ± 0,05 e 4,5 ± 0,05 dias, respectivamente, com viabilidade superior a 90 %. Os estágios larval, pré-pupal e pupal apresentaram duração média de 13,9 ± 0,07; 5,7 ± 0,07 e 9,6 ± 0,12 dias, respectivamente. A duração do ciclo biológico foi de 34 ± 0,11 dias em média. Ovos de S. cerelella não foram adequados para a manutenção de C. everes em laboratório, por interferir no desenvolvimento do predador.
