Insulina pancreática de ratos diabéticos tipo 1 submetidos a um protocolo de treinamento físico individualizado

Since diabetes mellitus is considered a world public health problem, the present study aimed to evaluate oral glucose tolerance (TTGo) and pancreatic insulin concentration (PIC) of type I diabetic rats subjected to an individualized exercise training protocol. A total of 40 adult Wistar rats were used, half of which induced to diabetes by alloxan (32 mg/kg) endovenous injection, and divided into four groups (10 per group): Sedentary Control (SC), Trained Control (TC), Sedentary Diabetic (SD) and Trained Diabetic (TD). The physical training consisted of swimming, 1 h/day, 5 days/week during 8 weeks, supporting overload equivalent to 90% of the individual anaerobic/aerobic metabolic transition determined at the beginning of the experiment. The rats of SD and TD groups presented body weight reduction in relation to controls, which was less accentuated in TD group. Water and food ingestion increased in the diabetic groups in relation to controls. The areas under the serum glucose curve during the GTTo of diabetic groups were higher than the controls. Physical training attenuated this elevation. The diabetic groups showed reduced PIC when compared to both control groups. The physical training protocol employed improved glucose homeostasis and attenuated the body weight loss of diabetic animals but did not alter pancreatic insulin concentration. © FTCD/FIP-MOC.

Propriedades físico-hídricas, desenvolvimento radicular e produtividade da soja em dois tipos de manejos de solo

The soybean culture is part of crop rotation used by irrigators from the southwestern region of São Paulo State that perform no-tillage soil management as a form of sustainable soil use. The objective of this work was to evaluate the effect of this conservationist practice on physicalhydric properties, soil compaction, root development, and soybean culture production components in relation to the conventional management. The experiment was conducted at the Buriti-Mirim Farm, Angatuba, SP, in Brazil, using an area irrigated by a center pivot system divided into two types of soil management: conventional and no-tillage. Although the no-tillage management presented higher soil density, lower water available and lower soil resistance to penetration, both soil managements showed no difference in relation to root development.

Relação do meio físico com o manejo sustentável de plantio de eucalipto em áreas de terrenos acidentados - A Fazenda Santa Edwirges, Vale do Paraíba, Sudeste do Brasil

This study intends to evaluate the effects of landscape physical elements (rocks and relief) associated with silviculture activities. The study was carried out on a small farm (Fazenda Santa Edwirges) covered by Eucalyptus forested situated in the Paraiba do Sul Basin, Southeast Brazil. The methodology consisted of detailed geological and geomorphological studies at 1:10,000 scale, and laboratory analysis of soil physical properties. The results showed three geologic-geomorphologic associations (ridge escarpment with granitic rocks, steep and gentle hills cut by shear zones and gentle hill with alluvial sediments) present high vulnerability for the development of the physical processes such as accelerated erosion landslides and flooding. In contrast, mountains associated with gneissic rocks present smaller vulnerability and high resilience for the development of the physical processes. The results have showed the importance of considering the interactions among landscape physical for the eucalyptus forest management contributing to a better selection area for eucalyptus cultivation and minimize adverse environment impact in road design.

Concentrações séricas de aspartato aminotransferase e creatinoquinase e concentrações plasmáticas de lactato em equinos da raça Mangalarga Marchador após exercício físico

The aim of this study was evaluate the influence of physical exercise (marcha gait) on serum values of CK and AST and plasmatic values of lactate in Mangalarga Marchador horses trained in Espirito Santo, Brazil. Serum and plasma samples were obtained from 15 horses in four different moments: rest (T0), 5 minutes (T1), 30 minutes (T2) and 2 hours (T3) after the exercise. Lactate analysis revealed values of 1.02 ± 0.41 mmol/L, 2.73 ± 2.43 mmol/L, 1.89 ± 1.24 mmol/L and 1.31 ± 0.60 mmol/L, respectively at T0, T1, T2 and T3. When evaluating AST, the results recorded in T0, T1, T2 and T3 were, respectively, 189.3 ± 56.0 UI/L, 223.9 ± 53.5 UI/L, 186.8 ± 25.8 UI/L and 193.9 ± 44.7 UI/L. Finally, the CK at moments T0, T1, T2 and T3 were, respectively, 113.4 ± 56.3 UI/l, 144.1 ± 70.9 UI/L, 143.0 ± 81.0 UI/L and 173.1 ± 128.0 UI/L. The results showed that marcha gait leaded to significantly increased in plasma lactate and did not alter serum AST and CK, suggesting that the equines used were conditioned to the physical exercised imposed.

Parâmetros físico-químicos da água e ocorrência de streptococcus spp. em criação intensiva de tilápia no estado do espírito Santo, Brasil

This study evaluated the influence of intensive farming of tilapia on physical and chemical parameters and on the occurrence of Streptococcus spp. in the water of the lake and of cages. Throughout a year, monthly samplings were taken in the rainy and dry seasons for a year, at two sampling sites, lake and net cages. For the determination of water quality, physical and chemical water parameters were evaluated and compared to the standards established by Conama Resolution no. 357/2005. The presence of Streptococcus spp. in the water was determined by plating on blood Agar and biochemical screening. Mean values of water parameters were tested using the Kruskal-Wallis test comparing sampling sites and seasons. Ammoniacal nitrogen (ammoniacal-N), total phosphorus (total-P) levels and occurrence of Streptococcus spp. have increased in the water of the net cages. The mean values of several parameters have decreased during the rainy period, except for pH, temperature and ammoniacal-N. Total-P and dissolved oxygen levels, during dry and rainy periods, respectively, exceeded the standard established for freshwater class 2, recommended for aquaculture, which can be harmful to the fish. Therefore, constant monitoring of the physical,chemical and microbiological water parameters is recommended since the Juara lake is also used for recreational purposes.

Sistemas de manejo e atributos físico-hídricos de um Latossolo Vermelho cultivado com milho

The purpose of this experiment was to evaluate the hydro-physical attributes of the Red Oxisol cultivated with maize in Jaboticabal, São Paulo State, Brazil, under different systems of use and periods of adoption of managements. The experiment was arranged in a completely randomized design with split-plot arrangement, with six replications and the treatments were: six years of no-tillage system (SPD6), eight years of no-tillage system (SPD8), ten years of no-tillage system (SPD10), conventional tillage system (SPC) and an adjacent area of native forest (NF). The soil penetration resistance (PR), density, macroporosity, microporosity of the soil in layers of 0-0.05; 0.05-0.10 and 0.10-0.20 m, and the saturated hydraulic conductivity (Kθ) in 0.15 m depth were evaluated. It was found that the PR conditions were favorable for the cultivation to 0.20 m, indicating a structure preserved even after soil chiseling. Furthermore, the Kθ in the soil showed similar behavior between SPC and periods of SPD, although this was shown in a part of maize cycle, macroporosity values near 0.10 m3 m-3 and soil water tensions near 0.09 MPa.
