Jornal de Pneumologia , 2003,
Abstract: INTRODU O: Bronquiectasias s o freqüentemente encontradas na prática médica no Brasil, levando a significativa morbidez e comprometimento da qualidade de vida de seus portadores. OBJETIVOS: Analisar aspectos diagnósticos e terapêuticos em uma série de pacientes com bronquiectasias atendidos em um servi o de doen as pulmonares. MéTODO: Sinais, sintomas, achados radiográficos e microbiológicos, e resultados terapêuticos foram estudados em 170 pacientes portadores de bronquiectasias hospitalizados no período de 1978 a 2001 - 62,4% do sexo feminino, 37,6% do masculino, com idade média de 37 anos, variando entre 12 e 88 anos. RESULTADOS: Antecedente de pneumonia na infancia foi detectado em 52,5% dos pacientes, de tratamento tisiológico em 19,8%; 8,8% tinham asma br nquica, e dois tinham síndrome de Kartagener. Os sintomas mais comuns foram tosse (100%), expectora o (96%) e estertores pulmonares (66%). As les es eram unilaterais em 46,5% dos casos. Pneumococo, H. influenzae ou flora mista estiveram presentes em 85% das amostras de escarro examinadas. Os 170 pacientes receberam inicialmente tratamento clínico à base de antibióticos e fisioterapia respiratória; 88 deles (52%) mais jovens, com les es menores e boa reserva funcional foram submetidos à cirurgia de ressec o pulmonar (82 unilaterais e seis bilaterais). Ocorreram dois óbitos hospitalares entre os pacientes que receberam tratamento exclusivamente clínico. Os pacientes tratados cirurgicamente tiveram acentuada melhora dos sintomas, raramente necessitando ser reinternados. CONCLUS ES: Os prolongados sintomas broncopulmonares foram permanentemente aliviados na maioria dos pacientes com bronquiectasias que puderam ir à cirurgia de ressec o pulmonar, diferentemente dos que seguiram com o tratamento clínico.

Abstract: exchangeable aluminum has been used in brazil as a criteria for lime requirements of soils during the last 16 years. quantities of limestone to be applied are generally low. with the present work this criteria was evaluated with results of field experiments. the experimental results were obtained in three locations, with five years of corn, one of cotton and one of soybeans on a red-yellow podzolic soil of mococa, three years of soybeans on a dark red latosol with medium texture of s?o sim?o, and four years of cotton on a latosol of guaíra. in all cases limestone was applied before the first crops, at four levels. soil samples were taken before each crop. yields increased even with doses of limestone superior to those sufficient for practical neutralization of exchangeable aluminum, indicating this to be an inadequate criteria to determine lime requirements of soils. base saturation of the cation exchange capacity at ph 7 is suggested as an alternative criteria.

Abstract: The objective of this study was to evaluate grain yield stability and adaptability from the fixed lines and cultivars of common bean of color and black comercial groups from IAPAR’s common bean breeding program, as well as to compare the methods of Wrick, Eberhart & Russell, Cruz et al. and AMMI. Three trials using the carioca group and two using the black group were conducted during the 2006/2007 water crop season and the 2007 dry crop season, in 27 environments in the State of Paraná. Each trial included 20 genotypes. The following genotypes were selected: LP 06 22 (G13) (carioca 1), LP 06 04 (G7) (carioca 2), LP 06 52 (G5), LP 06 54 (G7) e LP 06 65 (G18) (preto 1) e LP 06 73G9 (preto 2). All genotypes showed high grain yield potential with wide adaptability and stability. The environment more stable and more productive was Ponta Grossa – dry season for the all studied groups. As for the method comparisons, the Eberhart & Russell and Cruz et al. showed significant and positive correlation in 80% of the studied groups for genotypes stability and adaptability. O objetivo deste trabalho foi avaliar a estabilidade e adaptabilidade de produtividade de gr os das linhagens fixadas e cultivares de feij o do grupo comercial carioca e do grupo comercial preto, oriundas do programa de melhoramento genético do IAPAR e comparar os métodos de Wrick, Eberhart & Russell, Cruz et al. e AMMI. Na safra das águas 2006/2007 e seca 2007 foram conduzidos três ensaios do grupo carioca e dois do grupo preto, num total de 27 ambientes no estado do Paraná. Cada ensaio foi constituído por 20 genótipos. Os genótipos indicados foram LP 06 22 (G13) (carioca 1); LP 06 04 (G7) (carioca 2); LP 06 52 (G5), LP 06 54 (G7) e LP 06 65 (G18) (preto 1); e LP 06 73G9 (preto 2). Todos esses genótipos apresentaram alto potencial de produtividade de gr os com ampla adapta o e estabilidade. O ambiente mais estável e mais produtivo foi Ponta Grossa - seca para todos os grupos comerciais de feij o. Na análise de compara o entre os métodos, o método de Eberhart & Russel e Cruz et al. apresentaram correla o positiva e significativa em 80% dos grupos avaliados para a estabilidade e adaptabilidade dos genótipos.

Abstract: The compositions of essential oils from Chenopodium ambrosioides L. and Philodendron bipinnatifidum Schott were determined, and the their potential effects on the nutrition and mortality of Diabrotica speciosa were studied. The extraction of the oils was performed by hydrodistillation (2 h) using a modified Clevenger apparatus and the oils were subsequently subjected to analysis by gas chromatography/flame ionization detector (CG/FID) and gas chromatography/mass spectrometry (GC-MS). A completely randomized design with five treatments and four replications was adopted. The bean plants were sprayed with solutions of the oils dissolved in aqueous Tween 80 solutions at concentrations of 0 (water + Tween 80), 0.5%, 1.0%, 1.5% and 2.0% and then furnished to the insects with no choice available. Seven days after the application, the percentage of leaves with injury, degree of defoliation, the preference index for consumption and the percent of mortality of insects were evaluated. Neither of the essential oils caused a reduction in foliar injury, but antifeeding activity was observed, causing reduced feeding and increasing the mortality of adult D. speciosa insects.
