Condições de trabalho e transtornos mentais comuns em trabalhadores da rede básica de saúde de Botucatu (SP)

Os transtornos mentais comuns (TMC) apresentam elevada prevalência em populações gerais e de trabalhadores, com consequências individuais e sociais importantes. Este estudo, transversal e descritivo, explora a relação entre demandas psicológicas, grau de controle e presença de suporte social no trabalho e prevalência de TMC em trabalhadores da rede básica de saúde de Botucatu (SP). A coleta de dados foi feita por meio de questionário autoaplicável, não identificado, com destaque para itens relativos à demanda-controle-suporte e presença de TMC (Self Reporting Questionnaire, SRQ-20). As informações foram inseridas em banco de dados construído com Excel/Office XP 2003 e a análise estatística, efetuada com o programa SAS. Constatou-se que 42,6% dos trabalhadores apresentavam TMC. A observação de associação - alta prevalência de TMC com elevado desgaste (classificação de Karasek) e baixa prevalência de TMC com baixo desgaste - indica que, no município estudado, as condições de trabalho na atenção básica constituem fator contributivo não negligenciável ao adoecimento dos trabalhadores. Revela-se a necessidade de intervenções direcionadas ao cuidado aos trabalhadores, melhoria das condições de trabalho e aumento do suporte social no trabalho.

Relação entre a estrutura foliar de feijoeiro e a pré-infecção por Glomerella cingulata f.sp. phaseoli

Os objetivos deste trabalho foram mensurar a área da nervura secundária e quantificar o número de tricomas da superfície foliar de cultivares de feijoeiro suscetível (Carioca), moderadamente resistente (Pérola) e resistente (IAPAR-81) à antracnose, e observar as relações entre tais características com o estágio pré-infeccional. Para mensurar a área da nervura secundária, fragmentos foliares foram amostrados, fixados em FAA 50, conservados em álcool 70%, infiltrados em resina glicol-metacrilato, cortados transversalmente e corados com azul de toluidina. Os tricomas foram quantificados em impressões epidérmicas em microscópio de projeção. Na análise pré-infeccional, o material foi fixado em glutaraldeído 2,5% e processado para o estudo ao microscópio eletrônico de varredura. A cultivar resistente apresentou menor área de nervura secundária e maior pilosidade que a cultivar moderadamente resistente e a suscetível. Na cultivar resistente, por causa da menor área de nervura e maior pilosidade, o patógeno permaneceu sobre a nervura e envolvido com o tricoma. Na cultivar suscetível, com maior área de nervura e menor pilosidade, foram observadas necrose e estruturas fúngicas na superfície foliar. Há relação entre estas características foliares e a resistência à antracnose durante o estágio pré-infeccional do patógeno.

Assessment of the ichthyofauna in stretches under the influence of Salto Grande Reservoir (Middle Paranapanema River, SP/PR, Brazil).

Aim: To analyze the composition, species richness and spatial distribution of the fish fauna in the area under influence of the Salto Grande Reservoir; Methods: Fish were caught every two months from November/05 to October/06, using gill nets, seining nets and sieve; Results: It was registered 67 fish species, 1,964 individuals and 146.2 kg, representing CPUEn of 1,964 and CPUEb of 278 kg. The most representative orders were Characiformes, with 29 species, Siluriformes (21 species) and Perciformes (11 species) Nine non-native species were registered. The most abundant species in the reservoir were Astyanax altiparanae, Steindachnerina insculpta and Acestrorhynchus lacustris, indicating the predominance of medium and small fishes in this reservoir. The dendrogram of similarity separated the Dam and Pedra Branca stretches from Pardo River Mouth, indicating differences in the assemblages. The species turnover among the stretches was demonstrated by the beta diversity, which may be related to the diversity of habitat; Conclusions: Although being a small reservoir, it displays great habitat diversity, reflecting in the composition and structure of fish assemblages.

First report of Strongyloides sp. (Nematoda, Strongyloididae) in Leopardus tigrinus (Carnivora: Felidae) in the municipality of Botucatu, State of São Paulo, Brazil

O presente estudo reporta o primeiro caso de infecção por Strongyloides sp. em Leopardus tigrinus no município de Botucatu, Estado de São Paulo, Brasil. Fezes do exemplar parasitado de L. tigrinus foram cultivadas em fezes eqüinas esterilizadas e foi realizada infecção experimental em gato (Felis catus domesticus) com três mil larvas L3 infectantes por via subcutânea, para a identificação da espécie de Strongyloides envolvida no parasitismo. As fêmeas partenogenéticas obtidas do animal experimental foram analisadas porém a comparação dos dados biométricos encontrados com os dados da literatura não permitiu a identificação da espécie. Este é o primeiro relato sobre a ocorrência de Strongyloides sp. em L. tigrinus

Using chemical and physical parameters to define the quality of Pardo River water (Botucatu-SP-Brazil)

This paper aims to study the ecological system of the Pardo River, at the source and lower-order passages, which are in the Botucatu area, São Paulo State, Brazil. This study was carried out to determine water quality with some chemical-physical indicators, coliforms, and chemical species of samples taken monthly, 1995/02-1996/01, from eight sampling stations sited along the Pardo River. The results in the river monitoring are discussed based on annual averages, analysis of variance, and compared to Tukey's Studentized Range-HSD, and principal component analysis (PCA) was applied to normalize data to assess association between variables. We can conclude that the variables used are very efficient for identifying and that the dry season shows the worst water quality. These were caused by organic matter, nutrients (originate) from anthropogenic sources (spatial sources) and mainly municipal wastewater, affecting the quality and hydrochemistry of the river water, which have been differentiated and assigned to polluting sources. Meanwhile, the degree of degradation of the Pardo River is low (sewage treatment carried out by the city of Pardinho is efficient), leaving the water of the river suitable for use by the population of Botucatu, after conventional treatment (Conama, Resolucao No. 20, CONAMA, Brazilia DF, 09-23, 1986-the water of the Pardo river is classified as level 03).

Physical and chemical characteristics of the sediment in the estuarine region of Cananeia (SP), Brazil

Physical and chemical characteristics of sediment were analyzed at eight sampling areas in the estuarine region of Cananeia (SP), Brazil. The samples were collected in 1995 during four periods; summer, autumn, winter and spring. Total nitrogen and phosphorus concentrations, redox potential, water and organic matter percentage, sand and silt percentage and grain size were determined in six different layers of 20 cm deep columns of sediment. In general, the nutrient concentration and the percentage of organic matter decreased with depth and greater variations were observed in the first centimeter of the samples. Differences in nutrient concentration and organic matter were also observed during the study period. The highest concentrations were recorded during the rainy season (February) as a consequence of an accumulation of organic matter brought into the system by rivers and adjacent flooded areas. In general, the sediments had oxidized characteristics until the 5 or 10 cm depth in areas near the rich coastal vegetation. However, in areas open to the ocean, the entire sediment columns were almost completely oxidized.

Occurrence of shrimp species (Crustacea : Decapoda : Natantia : Penaeidea and Caridea) in Ubatuba Bay, Ubatuba, SP, Brazil

The species composition of Penaeidea and Caridea shrimp was studied in Ubatuba Bay, São Paulo, Brazil. Samples were taken monthly from September 1995 to August 1996, using two double-rig trawling nets. A total of 21 marine shrimps species were obtained, belonging to eight families. Sergestoids were represented by a single species of Sergestidae, while penaeoids comprised three families, Penaeidae, Sicyoniidae and Solenoceridae. Caridea shrimps belonged to two superfamilies, the Palaemonoidea, represented by Palaemonidae; and Alpheoidea by three families, Alpheidae, Ogyrididae and Hippolytidae. Sicyonia laevigata Stimpson, 1871 and Nematopalaemon schmitti (Holthuis, 1950) represent first records in São Paulo State, Brazil.

Biology and shell relationship in Clibanarius vittatus (Bosc, 1802) (Crustacea, Diogenidae) from Sao Vicente, SP, Brasil.

This study aimed to characterize the populational structure of Clibanarius vittatus (Bosc, 1802), as well as to determine the morphometric relations between the animal's size and the variables: length of their chelar propodus and the size of the shell opening. C. vittatus is a relatively abundant pagurid on the west Atlantic coast, it occurs in the intertidal region from 38 degrees N to 28 degrees S. The animals in this study were randomly sampled every month on the Paranapu (a) over tilde Beach (46 degrees 23' S e 23 degrees 59' W), S (a) over tilde $ o Vicente (SP), Brazil. The biometrics data were adjusted to the power equation (y = ax(b)), by means of the minimum square method. A total of 427 individuals were collected. The size of the cephalothoraxic shield ranged from 2.5 to 12.7 mm, evidencing a representative sample of the population. The of most commonly genus of Gastropoda shells occupied by the hermits was Thais (97,26%). In relation to the morphometric analyses performed, it was observed a positive correlation between the animal size and the variables length of the chelar propodus and the size of the shells.
