The present study aimed to evaluate the efficiency of the accelerated aging test to determination of the physiological potential of the Crambe abyssinica Hochst seeds, from two harvests (2009 and 2010). Were evaluated: water content, germination and vigor by germination speed index, accelerated aging in temperatures of 41, 43 and 45 °C for 24, 48, 72 and 96 hours, fresh and dry mass. The experiment was conducted in a 2x3x5 factorial (batches x temperature x exposure time), in a completely randomized design, with four replicates of 25 seeds. The fresh and dry mass were not effective for distinguish the physiological quality of Crambe abyssinica seeds. The accelerated aging test influences, similarly, the percentage of germination and vigor, with greater sensitivity when the seeds treated with temperatures of 41 or 43 °C, for 72 h, and evidenced promising role to a stratification of the physiological quality of crambe seeds batches with similar germination.

Este estudio tuvo como objetivo evaluar la eficacia de la prueba de envejecimiento acelerado, para determinar los efectos fisiológicos de semillas Crambe abyssinica Hochst, un montón de dos cosechas (2009 y 2010). Se evaluaron: contenido de agua, la germinación y el vigor por el índice de velocidad de la germinación, envejecimiento acelerado a 41, 43 y 45 °C durante períodos de 24, 48, 72 y 96 horas, el peso fresco y el peso seco. El experimento se llevó a cabo en el esquema factorial 2x3x5 (mucha x temperatura x tiempo de exposición), en un diseño completamente al azar, con cuatro repeticiones de 25 semillas. El peso fresco y peso seco no son eficientes para diferenciar la calidad fisiológica de las semillas de Crambe abyssinica. Las influencias de envejecimiento acelerado, de manera similar, el porcentaje de germinación y el vigor, con una mayor sensibilidad cuando las semillas son tratadas con temperaturas de 41 o 43 °C durante 72 h, lo que indica un papel prometedor para la estratificación de la calidad fisiológica de la semilla crambe de lotes con germinación similar.

O Estado do Rio Grande do Sul apresenta inúmeras diferenças no aspecto geográfico-econômico-ambiental. No presente trabalho, considera-se a divisão regional proposta por ALONSO et al. (1994), a qual apresenta o Estado dividido em três regiões: metade sul, metade norte e nordeste. Na metade sul, a economia é baseada no setor primário, tendo a pecuária, como principal produto. A metade norte tem sua economia baseada na agricultura e a região nordeste caracteriza-se pela presença de vários setores industriais, com grandes concentrações urbanas. Sabe-se que o consumo é influenciado pela idade, renda, nível de educação, padrão de mobilidade e gosto dos consumidores. O objetivo, neste trabalho, foi verificar o comportamento do preço de diferentes cortes de carne bovina, em nível de consumidor, nas três regiões econômicas do Estado. A pesquisa caracterizou-se por um levantamento mensal em supermercados, durante os anos agrícolas 2006/2007 e 2007/2008, do preço de diferentes cortes de carne bovina em onze cidades. Os menores e os maiores preços da carne bovina verificados nas regiões metade Sul e nordeste, respectivamente, decorrem provavelmente do fato de que uma é a região produtora e a outra principal consumidora. Outro resultado importante é que as maiores variações, no preço dos cortes, ocorreram também nessas regiões. Portanto, num cenário em que a demanda é maior que a oferta, essas regiões parecem ser as primeiras a receberem o impacto nos preços da carne bovina.

The State of Rio Grande do Sul presents various situations considering geographical, economical and environmental aspects. This study considers the regional division suggested by ALONSO et al. (1994): Southern half, Northern Half and Northeast. The primary sector is the base of Southern half economy and livestock production is its main product. The Northern half has crop production as its main economical resource, while the Northeast is characterized by the presence of various industrial sectors and large urban concentration. Consumer preferences are directly influenced by age, income, level of education, patterns of mobility and personal taste. The aim of this study was to verify price behaviour of different beef cuts. The research was done through a monthly data collection in supermarkets, during the periods of 2006/2007 and 2007/2008, considering the price of different beef cuts in eleven cities. The lowest and highest prices of beef cuts were verified in the Southern half and in the Northeast, respectively, which is probably due to the fact that one is the main producer and the other is the main consumer. Another important result is that the highest price variation in beef cuts also happened in these regions. Thus, when there is a higher demand than supply, the first to receive these impact on price are these regions.

OBJETIVO: Comparar achados ultrassonográficos e de ressonância magnética na endometriose profunda, com ênfase para o comprometimento intestinal. MATERIAIS E MÉTODOS: Dezoito pacientes entre 23 e 49 anos de idade, com suspeita clínica e exame ginecológico sugestivo de endometriose profunda, foram submetidas a ultrassonografia e ressonância magnética para correlação dos achados. RESULTADOS: A ultrassonografia detectou 40 lesões e a ressonância magnética detectou 53 lesões na pelve. O estudo comparativo entre ultrassonografia e ressonância magnética na detecção das lesões não mostrou diferença estatística significativa (p > 0,19 e p > 0,14, respectivamente). Considerando-se a junção retossigmoide, a ressonância magnética detectou uma lesão (5,6%) e a ultrassonografia apontou quatro lesões (22,2%). Nas lesões retais, a ultrassonografia apontou oito lesões (44,4%) e a ressonância magnética, sete lesões (38,9%). CONCLUSÃO: A concordância entre a ressonância magnética e a ultrassonografia não foi boa na junção retossigmoide e no reto, sendo que a ultrassonografia detectou um número maior de lesões nessas localizações, mas identificou número menor de lesões na pelve. Na análise comparativa global entre os dois métodos na detecção das lesões não houve diferença estatística significativa. O baixo custo, a boa tolerabilidade e o fácil acesso tornam a ultrassonografia instrumento diagnóstico valioso na endometriose profunda.

OBJECTIVE: To compare sonographic and magnetic resonance imaging findings in deep endometriosis with emphasis on intestinal involvement. MATERIALS AND METHODS: Eighteen women aged between 23 and 49 years with clinical suspicion and gynecological signs suggestive of deep endometriosis were submitted to ultrasonography and magnetic resonance imaging for correlation between findings. RESULTS: Ultrasonography detected 40 lesions while magnetic resonance imaging detected 53 lesions in the pelvis. A comparative study has not shown any statistically significant intermethod difference in the detection of lesions (respectively p > 0.19 and p > 0.14). In the rectosigmoid junction, magnetic resonance imaging has detected one (5.6%) lesion, while ultrasonography has detected four lesions (22.2%). In the rectum, ultrasonography has detected eight lesions (44.4%), and magnetic resonance imaging has detected seven lesions (38.9%). CONCLUSION: The intermethod agreement has not been good for lesions in the rectosigmoid junction, considering that ultrasonography has detected a higher number of lesions in this region, but a lower number of lesions in the pelvis as compared with magnetic resonance imaging. The global comparative analysis has demonstrated no statistically significant intermethod difference in the detection of lesions. Low cost, good tolerability and high availability make ultrasonography a valuable diagnostic tool in cases of deep endometriosis.

OBJECTIVE: To evaluate the safety and effectiveness of trabeculectomy with mitomycin C in the management of childhood glaucoma. INTRODUCTION: The use of antifibrotic agents enhances the success of trabeculectomy performed in both adults and children. METHODS: A retrospective chart review (1991-2001) of 114 patients (114 eyes) from 0-14 years of age with congenital or developmental glaucoma. These patients underwent trabeculectomy with mitomycin but had not been previously treated with any antifibrotic agent. RESULTS: The mean patient age was 57.36 51.14 months (range: 0.5-168 months). Treatment was considered successful in 63 eyes (55.26%), with a mean intraocular pressure of 12.11 3.98 mmHg. For patients categorized as successfully treated, the mean follow-up time was 61.16 26.13 months (range 12-113 months). A post-surgical intraocular pressure of < 16 was observed in 47 eyes. The life-table success rates for intraocular pressure control at 24, 36, 48, and 60 months were 90.2%, 78.7%, 60.7% and 50.8%, respectively. The cumulative probability of failure was 40.8% at 12 months. Following surgery, endophthalmitis appeared in eight eyes (4.88%) after an average 36.96 months (range: 1.7-106 months). Other complications included expulsive hemorrhage, flat anterior chamber and bleb leak. DISCUSSION: It has been reported in pediatric patients that trabeculectomy without adjunctive antimetabolites achieves a successful outcome in 30% to 50% of cases. In our study, treatment was considered successful in 63 eyes (55.26%) within 61.16 26.13 months of follow-up. CONCLUSIONS: Trabeculectomy with mitomycin is safe and effective for short-term or long-term treatment of congenital or developmental glaucoma. The frequency of bleb-related endophthalmitis was no higher in these patients than that described in adults.

O receio em nosso meio, em se retardar, erroneamente, a revascularização do miocárdio (RM) em pacientes idosos determinou a realização deste estudo. Um total de 361 pacientes foram, consecutivamente, submetidos a RM entre 1992 e 1995, no InCór, dos quais 30,7% eram mulheres, 69,3% homens; 36,7% encontravam-se em classe funcional III/IV. Foi realizada análise univariada com 19 fatores perioperatórios e, a seguir, multivariada (regressão logística) com as variáveis que mostraram associação significativa (p < 0,005). Os fatores prognósticos da morbidade operatória foram: diabete melito, ICC, angina instável. Os pós-operatórios foram: acidente vascular cerebral, insuficiência renal, infecção e suporte respiratório prolongado. Concluímos que a revascularização do miocárdio pode ser realizada em pacientes com idade avançada, acompanhada de excelentes resultados (baixa mortalidade operatória) especialmente pacientes em classe funcional de ICC não muito avançada, propiciando melhora significativa da qualidade de vida.

The trend in Brazil of erroneously delaying myocardial revascularization in the elderly determined this study. Three hundred consecutive elderly patients (mean age: 73,92, standard deviation: 3.32). Between October 1992 and July 1995, 361 consecutive patients underwent isolated coronary artery bypass grafting, of whom 111 (30,7%) were females and 250 (69,35) males. There were 128 (35,5%) diabetic patients and 128 (36,7%) were in NYHA III/IV. Univariate analysis per-operatory of 19 factors followed by multivariate logistic regression analysis of the significant variables (p 0.005) were done. Major complication ocurred in 178 (49.3%) and were independent predictors of operative morbidity: Diabetes mellitus, NYHA funcional classification, urgent cases and DP2. There were 33 (9,1%) in hospital deaths, and diabetes mellitus, NYHA functional classification, unstable pre-operative angina and cerebral vascular acidents, renal failure, infection and insufficiency respiratory failure were independent predictors of operative mortality. We concluded that coronary artery bypass grafting is possible in elderly patients with a favorable outcome, especially when done in patients with normal to moderately depressed left ventricular function.
