ABSTRACT Soil compaction negatively impacts soil physical functions, affecting root growth and crop yield. This study aimed to evaluate different soybean cultivars’ agronomic and physiological performance as a function of compaction in Rhodic Ferralsol under no-tillage (NT) with a clay loam texture in the Brazilian Cerrado biome. The experiment was implemented in Rio Verde, Goias state, central Brazil. The experimental design was a randomized block with a 3x2 factorial scheme with six replications. The first factor corresponded to three soybean cultivars from different maturity groups (MG) identified as super-early (MG = 6.2); early (MG = 6.8), and medium (MG = 7.9). The second factor was the cultivation in compacted and uncompacted soil. The experiment evaluated the soil physical properties: bulk density, total porosity, water content at matric potential -6 kPa, aeration capacity and water and air holding capacity in 0.0-0.1 and 0.1-0.2 m layers, agronomic and physiological traits (gas exchange). Soil compaction negatively affected the agronomic traits of soybean cultivars, with better performance of the medium cycle cultivar. Net photosynthesis, stomatal conductance, and transpiration rates were reduced up to 50% under compaction and were not influenced by cultivars. Our findings suggest that soil compaction negatively affected the performance of soybean cultivars with lower maturity groups reflecting in lower plant height, shoot and root dry mass, number of pods and grain yield. The choice of soybean cultivars with a longer cycle can be an alternative to minimize the adverse effects of soil compaction.

ABSTRACT The fungus that causes Asian soybean rust, Phakopsora pachyrhizi, shows crossed and multiple resistance to the three chemical groups of site-specific fungicides (triazoles, strobilurins and carboxamides). This fact evidences the need to implement strategies for the preventive management of resistance. An alternative can be the use of microorganisms capable of interfering in the development of pathogens, as well as of acting as resistance inducers in the plants. The objective of the present study was to evaluate the efficacy of a biological product based on Bacillus subtilis BV02, alone or in association with a copper-based product, on Asian soybean rust control, as well as the agronomic performance of soybean. Thus, two experiments were developed, one in the field and another one in the laboratory. For the experiment conducted in the field, a randomized block design was used with (5x2)+1 factorial arrangement of treatments, including four replicates. The first factor corresponded to application, during post-emergence of soybeans, of five B. subtilis BV02 doses (0, 0.5, 1.0, 2.0 or 4.0 L c.p. ha-1). The second factor corresponded to association or not with a copper-based product. The additional treatment consisted of applying the fungicide association [azoxystrobin + benzovindiflupyr] + mancozeb. In the laboratory experiment, germination of Phakopsora pachyrhizi uredospores in Elisa plates was evaluated in a completely randomized design with eight replicates. Treatments were the same as those adopted in the field experiment, except for the chemical fungicide, since mancozeb was not added to the sprayed broth. Increasing doses of B. subtilis BV02, applied alone, provided reductions in Asian soybean rust severity, and this behavior was not observed when it was applied in association with the copper-based product. Considering the association between B. subtilis BV02 and the copper-based product, the best Asian rust control results were found with doses equal or inferior to 1.0 L c.p. ha-1. Soybean yield was superior to that of the treatment containing fungicides with the use of B. subtilis BV02 alone (1.0 and 2.0 L c.p. ha-1), with application of only a copper-based product and with the combination of this micronutrient with B. subtilis BV02 (2.0 L c.p. ha-1).

RESUMO O fungo causador da ferrugem asiática na soja, Phakopsora pachyrhizi, apresenta resistência cruzada e múltipla aos três grupos químicos (triazóis, estrobilurinas e carboxamidas) de fungicidas sítio-específicos. Este fato torna evidente a necessidade da implementação de estratégias para o manejo de prevenção da resistência. Uma alternativa pode ser a utilização de microrganismos com capacidade de interferir no desenvolvimento de patógenos, bem como atuarem como indutores da resistência das plantas. O objetivo do presente trabalho foi avaliar a eficácia de produto biológico à base de Bacillus subtilis BV02 isolado ou associado à produto à base de cobre no controle de ferrugem asiática, bem como desempenho agronômico da soja. Para tanto, foram instalados dois experimentos, sendo um no campo e outro em laboratório. Para o experimento conduzido em campo, o delineamento utilizado foi o de blocos ao acaso, estando os tratamentos dispostos em arranjo fatorial (5x2)+1, com quatro repetições. O primeiro fator correspondeu a aplicação, em pós-emergência da soja, de cinco doses de B. subtilis BV02 (0, 0,5, 1,0, 2,0 ou 4,0 L p.c. ha-1). O segundo fator correspondeu a associação ou não com produto à base de cobre. O tratamento adicional consistiu na aplicação da associação entre os fungicidas [azoxystrobina + benzovindiflupir] + mancozebe. No experimento em laboratório foi avaliada a germinação dos uredósporos de P. pachyrhizi em placas Elisa, no delineamento inteiramente casualizado com oito repetições. Foram utilizados os mesmos tratamentos do experimento do campo, diferenciando-se apenas o fungicida químico, o qual não foi adicionado mancozebe a calda aplicada. O aumento de dose de B. subtilis BV02, aplicado isoladamente, proporcionou reduções na severidade de ferrugem, não sendo visualizado este comportamento quando associado ao produto à base de cobre. Para a associação entre B. subtilis BV02 e produto à base de cobre, os melhores resultados para o controle de ferrugem asiática foram visualizados em doses iguais ou inferiores a 1,0 L p.c. ha-1. A produtividade da soja foi superior ao tratamento contendo fungicidas com a utilização de B. subtilis BV02 isolado (1,0 e 2,0 L p.c. ha-1), com aplicação apenas de produto à base de cobre e com utilização deste micronutriente em associação ao B. subtilis BV02 (2,0 L p.c. ha-1).

RESUMEN El espaciamiento entre hileras comúnmente utilizado en el cultivo de yuca en Brasil, especialmente en la región de Agreste de Alagoas, varía de 100 a 120cm. Sin embargo, la reducción del espacio entre hileras puede promover ganancias agronómicas y ambientales en los sistemas de cultivo con yuca. Por lo tanto, el objetivo de este trabajo fue evaluar el comportamiento de dos variedades de yuca cultivadas con espaciamiento reducido entre hileras. Se realizaron dos experimentos en el campo, uno en el 2015/16 y otro en el 2017/18. El diseño experimental utilizado en ambos experimentos fue el de Parcelas Divididas con cuatro repeticiones. Se evaluaron cuatro espaciamientos entre filas en la parcela principal: 60, 80, 100 y 120cm, con plantas espaciadas 60cm dentro de las hileras, dando poblaciones de 27,778, 20,833, 16,667 y 13,889 plantas por hectárea, respectivamente. En las subparcelas se evaluaron dos variedades de yuca: Caravela y Pretinha. Un aumento en el espaciamiento entre hileras promovió una reducción lineal en la masa verde del tallo de la yuca. La altura de la planta, la masa verde de la hoja, el diámetro del tallo principal, el rendimiento de la raíz, la longitud de la raíz tuberosa, el diámetro de la raíz tuberosa, el porcentaje de harina, el rendimiento de la harina y el contenido de almidón no se vieron afectados por los cambios en el espaciamiento entre hileras. La variedad Pretinha fue superior a Caravela en las siguientes características evaluadas: masa verde del tallo, diámetro de raíces tuberosas, rendimiento de raíces, altura de planta y rendimiento de harina. Los resultados indican la posibilidad de alterar el espaciamiento entre hileras en la yuca para ayudar en el manejo cultural, sin afectar el rendimiento del cultivo.

ABSTRACT The interrow spacing commonly used in cassava cultivation in Brazil, especially in the Agreste region of Alagoas, ranges from 100 to 120cm. However, the reduction in row spacing can provide agronomic and environmental benefits in cassava cropping systems. Thus, this work aimed to evaluate the performance of two cassava varieties cultivated with reduced interrow spacing. Two experiments were conducted in the field, one in 2015/16 and another in 2017/18. A Split Plot design with four replications was used in both experiments. Four interrow spacing were evaluated in the main plot: 60, 80, 100 and 120cm, with plants spaced 60cm apart within rows, giving populations of 27,778, 20,833, 16,667 and 13,889 plants per hectare, respectively. In the subplots, two cassava varieties were evaluated: Caravela and Pretinha. An increase in interrow spacing promoted a linear reduction in the stem green mass of cassava. Plant height, leaf green mass, main stem diameter, root yield, tuberous root length, tuberous root diameter, flour percentage, flour yield, and starch content were not influenced by changes in interrow spacing. The Pretinha variety was superior to Caravela in the following evaluated traits: stem green mass, the diameter of tuberous roots, root yield, plant height, and flour yield. The results indicate the possibility of altering the interrow spacing in cassava to assist in the cultural management, without impacting crop yield.

ABSTRACT. The succession of soybean/maize has been largely adopted. Storm damage and crop problems can lead to grain loss, generating maize ear fragments or even whole ears that remain in the soil and still display germination viability, resulting in the occurrence of volunteer plants. In this context, the present study aimed to evaluate the interference of voluntary maize plants on soybean and investigate the susceptibility of maize hybrids to pre-emergence herbicides. In the first step, an experiment was performed evaluating the influence of voluntary maize plant density and spatial distribution on soybean. The experiment was performed in a randomized completely block design (RCBD) with four replications, with treatments disposed in factorial arrangement (2 x 4) + 1. The first factor corresponded to the spatial distribution of maize plants: row or in between soybean rows; while the second factor adopted four infestation densities of maize plants m-2: 4, 8, 12, and 16. The additional treatment consisted of a control without maize plants. For the second step, an experiment was conducted in two locations aiming to determine the efficacy of pre-emergence herbicides in the control of voluntary maize. Both experiments were installed in RCBD in a split-plot scheme with four replications. Fomesafen, lactofen, sulfentrazone, chlorimuron-ethyl, diclosulam, flumetsulam, imazethapyr, clomazone, metribuzin, [sulfentrazone + diuron], [imazethapyr + flumioxazin], and a control without herbicide application were evaluated in the main plot. In each subplot, the maize hybrids DKB310 PRO3™ and DKB390 PRO3™ were evaluated. No influence on the position of voluntary maize on the soybean yield was observed. The presence of the maize population led to a progressive decrease in soybean yield, ranging up to 86%, at 16 plants m-2. DKB390 displayed a stand reduction of 82.88% after the use of diclosulam. Diclosulam led to better results regarding maize plant decreases for both hybrids.

Materiales y métodos: estudio cuantitativo, exploratorio, transversal y descriptivo, realizado con datos secundarios de cinco municipios ubicados en el estado de Minas Gerais. Resultados: se atendieron a 54.206 pacientes con cáncer, predominantemente hombres (53,38 %), en un rango etario de 60 a 79 años (49,95 %), blancos (79,08 %), con educación básica primaria incompleta (48,36 %) y casados (57,34 %). Las neoplasias de piel representan la localización primaria más frecuente (22,35 %). La etapa I del tumor fue la más observada (20,98 %). Las razones más frecuentes para no tratar, después de la opción "no se aplica", fueron enfermedad avanzada, falta de condiciones clínicas u otras (6,97 %), mientras que se verificó el predominio de la enfermedad estable (31,59 %) al final del primer tratamiento recibido. Conclusión: los resultados presentados brindan apoyo para identificar las prioridades de la atención oncológica y establecen la configuración de la atención para pacientes con cáncer, lo que dirige la planificación de las intervenciones para proporcionar atención de calidad.

Abstract Objective: to know the epidemiological configuration of cancer care in a health macro-region in the Brazilian state of Minas Gerais between 2008 and 2017. Materials and methods: quantitative, exploratory, cross-sectional and descriptive study, conducted with secondary data from five municipalities of the state of Minas Gerais. Results: there were 54,206 visits to cancer patients, predominantly male (53.38%), aged 60 to 79 years (49.95%), white (79.08%), with incomplete elementary school education (48.36 %), and married (57.34 %). Skin neoplasms represent the most frequent primary location (22.35%). Stage I of the tumor was the most observed (20.98 %). The most prevalent reasons for not treating after the "not applicable" option were advanced disease and lack of clinical conditions or other conditions (6.97 %), whereas stable disease (31.59%) prevailed at the end of the first treatment received. Conclusion: the results provide support to identify the priorities of cancer care and outline the configuration for cancer treatment in patients, which directs the planning of interventions to provide high quality care.

ABSTRACT Weed management consists of a fundamental practice in cassava, with mechanical and chemical control widely used. The objective of this work was to evaluate the efficacy of pre-emergence herbicides, as well as to determine the interaction of these with weeding complementation in the weed management in cassava. Two experiments were conducted in Junqueiro (Alagoas). In 2015/16, the experimental design was based on randomized blocks, with treatments distributed in a split-split-plot scheme, with four replications. In the main plot, four pre-emergence associations of clomazone + flumioxazin in different doses were evaluated, in addition to a control without herbicide. In the subplots, the Caravela and Pretinha cassava cultivars were evaluated, while in the sub-subplots the control complementation was evaluated using or not the manual weeding. In the 2016/17, the plot design and layout remained the same as for 2015/16, except for the composition of the herbicide treatments, since the standardization of clomazone dose has been chosen, varying only the doses of flumioxazin. The association of clomazone and flumioxazin has shown efficacy in weed control, with a greater residual as higher doses are used. This association provided higher shoot and root yield. Weeding complementation along the cassava cycle can increase its yield.

RESUMO A disposição espacial em que plantas se encontram na área de cultivo é fator que influencia diretamente na produtividade de grãos, pois o melhor arranjo entre essas pode resultar em maior aproveitamento de água, luz e nutrientes. O objetivo do trabalho foi avaliar o desempenho agronômico de sorgo semeado em espaçamento de fileiras duplas no Cerrado. Para tanto, foi conduzido nas safrinhas de 2018 e 2019, experimentos de campo em delineamento de blocos completos em esquema fatorial 2 x 5, com quatro repetições, em que se utilizou dois espaçamentos de entrelinhas de semeadura: tradicional (0,50 m) e fileiras duplas (0,25 m/0,75 m) e cinco populações de plantas: 120, 180 (recomendada), 240, 300 e 360 mil plantas ha-1. Foram avaliadas características morfológicas, componentes do rendimento e produtividade de grãos utilizando análise conjunta dos dados para os dois anos de estudo. Em 2018, devido ao menor volume de chuvas durante o ciclo da cultura, a utilização do arranjo em fileiras duplas apresentou produtividade de grãos inferior ao espaçamento tradicional. Por outro lado, em 2019, ano com melhor distribuição hídrica, a produtividade foi superior a 2018. O aumento da população de plantas por hectare incrementou a produtividade de grãos de sorgo, com ganhos de até 24% em relação à população recomendada de 180 mil plantas ha-1, demonstrando que o adensamento nessa cultura pode ser uma técnica promissora desde que levado em consideração seu custo/benefício.

ABSTRACT The spatial arrangement of plants in the cultivation area is a factor that directly influences grain yield, since the best arrangement can result in the greater use of water, light and nutrients. The aim of the study was to evaluate the agronomic performance of sorghum sown in double row spacing in the Brazilian Cerrado. For this purpose, field experiments were conducted in the 2018 and 2019 seasons in a complete block design with a factorial scheme of 2 x 5. There were four replications, using two row spacing: traditional (0.50 m) and double rows (0.25 m/0.75 m) and five plant populations: 120, 180 (recommended), 240, 300 and 360 thousand, plants ha-1. Morphological characteristics, yield components and grain yield were evaluated using joint data analysis for the two years of study. In 2018, due to lower rainfall during the crop season, the use of a double row arrangement presented grain yield lower than traditional spacing. On the other hand, in 2019, the year with the best water distribution, the yield was superior to that of 2018. The increase in plant population per hectare increased the yield of sorghum grains, with gains of up to 24% in relation to the recommended population of 180 thousand plants ha-1, demonstrated that the densification in this crop can be a promising technique as long as its cost/benefit is considered.

RESUMO Objetivou-se analisar a satisfação dos usuários e a caracterização dos serviços de atendimento hospitalar e ambulatorial do Sistema Único de Saúde (SUS). Realizou-se um estudo transversal analítico por meio de dados de usuários que responderam ao instrumento Carta SUS entre 2012 e 2013, no estado do Rio Grande do Norte, no qual foi avaliada a qualidade da estrutura física, da equipe de saúde e do tratamento ofertado. Dos 17.333 usuários que responderam à Carta SUS no período estudado, 62,3% eram mulheres e 62,4% tinham acima de 40 anos. A maior parte dos atendimentos (56,8%) foi realizada na capital e em serviços públicos (70,3%). Os usuários apresentaram-se satisfeitos com os serviços, com um percentual que variou de 79 a 90%, de acordo com as regiões de saúde. Os homens e as pessoas com mais de 60 anos avaliaram mais positivamente os serviços; a alta complexidade e os serviços da capital tiveram melhores resultados (p≤0,001), assim como as unidades privadas. Ressaltam-se a importância da avaliação em saúde e a relevância de se analisar, divulgar e dar continuidade ao instrumento Carta SUS, com vistas a subsidiar mais estudos e reflexões sobre a qualidade dos serviços.

A cross-sectional analytical study was performed using user data that responded to the Carta SUS instrument between 2012 and 2013, in the state of Rio Grande do Norte, in which the quality of the physical structure, the health team and the treatment offered. Of the 17.333 users who answered the SUS Charter in the period studied, 62.3% were women and 62.4% were over 40 years old. Most of the attendances (56.8%) were held in the capital and in public services (70.3%). The users were satisfied with the services, with a percentage that ranged from 79 to 90%, according to the health regions. Men and people over 60 evaluated services more positively; the high complexity and the services of the capital had better results (p≤0.001), as well as the private units. The importance of health evaluation and the relevance of analyzing, disseminating and giving continuity to the SUS Charter instrument is emphasized, with a view to subsidizing further studies and reflections on the quality of services.

Abstract: En | Text: En | PDF: En

The effect of alcaline and hot water surface treatments of piassava Attalea funifera fibers was investigated. The efficiency of each treatment was evaluated by Fourier transform infrared spectroscopy, X-ray diffractometry, optical microscopy, scanning electron microscopy and atomic force microscopy. The alkaline treatments were effective in removing the superficial lignin layer from the fiber, while the hot water treatment was not. Treatment with hot water and NaOH caused fiber defibrillation. NaOH was most effective in promoting both, a decrease in fiber diameter and an increase in fiber surface area. Treatment with Ca(OH)2 led to the formation of a CaCO3 layer deposited on the fiber, preventing defibrillation. The crystalline structure of the fiber was not altered by any of the treatments, maintaining type I cellulose.

Resumo Existem vários modelos em bioética capazes de contribuir para tomada de decisão em saúde. O modelo da casuística trabalha com análise de casos reais para se tomar decisões diante de problemas bioéticos. Trata-se de estudo descritivo, qualitativo, a partir de análise temática, realizado com 16 acadêmicos da área de saúde com o objetivo de identificar suas experiências no processo de ensino-aprendizagem em bioética a partir do método de casos, fundamentado no modelo da casuística. Emergiram duas categorias: “o modelo da casuística como facilitador da formação do posicionamento ético e do processo de tomada de decisão” e “a dificuldade da aplicação prática dos paradigmas e analogias no modelo da casuística”. A partir das experiências relatadas, conclui-se que o modelo da casuística contribui significativamente para a tomada de decisão em problemas bioéticos, bem como auxilia o processo de ensino-aprendizagem de bioética durante a graduação na área da saúde.

Abstract There are several bioethical models capable of contributing to decision making in health. The casuistic model works with the analysis of real cases for decision making regarding bioethical problems. It is conducted with 16 academic scholars from the health field with the objective of identifying academic experiences in the teaching-learning process of bioethics. It uses the case method, based on the casuistic model. It is a descriptive, qualitative study using thematic analysis, where two categories emerged: “the difficulty of practical application of paradigms and analogies in the casuistic model’’ and ‘’how the casuistic model facilitates the formation of ethical positioning and the decision making process’’. From the reported experiences, it is concluded that the casuistic model significantly contributes to decision making in bioethical issues and assists in the teaching- -learning process of bioethics during undergraduate study in the health field.

Este estudio tiene como objetivo identificar las experiencias académicas en el proceso de enseñanza-aprendizaje de bioética a partir del método de casos, con base en el modelo de la casuística. Se trata de estudio descriptivo y cualitativo, a partir del análisis temático, realizado con 16 académicos de la salud. Surgieron dos categorías: “el modelo de la casuística como un facilitador en la formación de la posición ética y el proceso de toma de decisiones’’ y “la dificultad de la aplicación práctica de los paradigmas y analogías en el modelo de la casuística”. A partir de los experimentos relatados, se concluye que el modelo de la muestra contribuye significativamente a la toma de decisiones en cuestiones de bioética y ayuda positivamente en el proceso de la enseñanza-aprendizaje de bioética durante la graduación en salud.

RESUMO: Objetivou-se avaliar a eficácia do firocoxib no controle da quebra da barreira hematoaquosa experimentalmente induzida em gatos saudáveis e com sorologia positiva para toxoplasmose. Para tanto, utilizaram-se trinta e dois gatos sem alterações oculares, alocados em grupos (n=8/cada) compostos por gatos saudáveis que receberam tratamento prévio com 5mg g-1 de firocoxib oral (HF) ou sem nenhum tratamento (CH) no dia 0, e por gatos com sorologia positiva para toxoplasmose tratados de maneira similar (FT e CT). No dia 1, os gatos de todos os grupos receberam o mesmo protocolo de tratamento do dia anterior e, 1h depois, foram submetidos à paracentese da câmara anterior sob anestesia geral (M0). Após 1h, realizou-se nova paracentese (M1). Mediante a colheita de humor aquoso (M0 e M1), quantificaram-se os valores de proteína total e prostaglandina E2 (PGE2) das amostras. As amostras dos gatos com sorologia positiva para toxoplasmose foram também testadas para anticorpos anti- T. gondii IgG específicos. Em M0, as amostras de humor aquoso de CT apresentaram concentração de PGE2 significativamente superior aos demais grupos (P<0,05). Em todos os grupos, a concentração de PGE2 aumentou significativamente de M0 para M1 (P=0,001), no entanto, não houve diferença significativa entre os grupos em M1 (P=0,17). Anticorpos anti -T. gondii IgG específicos foram encontrados somente em amostras de M1, e os títulos não diferiram significativamente entre FT e CT (P=0,11). Valores de PGE2 significativamente superiores no CT durante M0 não foram capazes de induzir a quebra da barreira hematoaquosa e causar uveíte anterior nos gatos deste estudo. O firocoxib, por sua vez, não foi capaz de prevenir a quebra da barreira hematoaquosa após realização de paracente na câmara anterior em gatos saudáveis e com sorologia positiva para toxoplasmose.

ABSTRACT: This study aimed to evaluate the effects of firocoxib for controlling experimentally-induced breakdown of the blood-aqueous barrier in healthy and Toxoplasma gondii -seropositive cats. Thirty two cats with no ocular abnormalities were used. Groups (n=8/each) were formed with healthy cats that received 5mg g-1 of oral firocoxib (FH) or no treatment (CH) on day 0; seropositive cats for anti -T. gondii specific immunoglobulin G (IgG) were grouped (n=8/each) and treated in a similar fashion (FT and CT). On day 1, cats of all groups received the same treatment protocol, and 1h later, aqueocentesis was performed under general anesthesia (M0). Following 1h, the same procedure was repeated (M1). Quantitation of aqueous humor total protein and prostaglandin E2 (PGE2) were determined. Aqueous samples of seropositive cats were tested for anti- T. gondii specific IgG. In M0, aqueous samples of CT showed a significantly higher concentration of PGE2 in comparison with other groups (P<0.05). In all groups, PGE2 concentration increased significantly from M0 to M1 (P=0.001). PGE2 values did not change significantly between groups in M1 (P=0.17). Anti- T. gondii specific IgG were reported only in samples of M1, and aqueous titers did not change significantly between FT and CT (P=0.11). Although we have observed that aqueous humor PGE2 levels were significantly higher in cats of CT group during M0, such increase was not able to break the blood-aqueous barrier and cause anterior uveitis. Firocoxib did not prevent intraocular inflammation after aqueocentesis, in healthy and toxoplasmosis-seropositive cats.

Abstract: En | Text: En | PDF: En

The present study investigated the effect of supplementation of vitamin E on streptozotocin (STZ)-induced diabetic rats by measuring blood glucose, changes in body weight, food and water intake, lipid profile, serum urea and creatinine level, and antioxidant enzyme activity. Male Wistar rats were divided into four groups: control rats (GI); rats receiving vitamin E (GII); STZ-induced diabetic rats (GIII) and STZ-induced diabetic rats treated with vitamin E (GIV). Vitamin E reduced (p<0.05) blood glucose and urea, improved the lipid profile (decreased the serum levels of total cholesterol, LDL cholesterol, VLDL cholesterol and triacylglycerols, and increased HDL cholesterol) and increased total protein in STZ-induced diabetic rats (GIV). Vitamin prevented changes in the activity of SOD and GSH-Px and in the concentration of lipid hydroperoxide. These results suggested that vitamin E improved hyperglycaemia and dyslipidaemia while inhibiting the progression of oxidative stress in STZ-induced diabetic rats.
