COMPARACAO ENTRE MEDICAMENTOS ORAIS ATRAVES DAS TAXAS SERICAS DE GLICOSE, AMILASE, ACIDOS GRAXOS LIVRES E LIPOPROTEINAS DE ALTA DENSIDADE (HDL-COLESTEROL) NOS DIABETICOS DE AMBOS OS SEXOS, DA REGIAO DE ARARAQUARA, NAO-DEPENDENTES DE INSULINA

A study was carried out, on both sexes, to determine the effects of chlorpropamide (DIABINESE) and glibenclamide (DAONIL) on patients with Type II diabetes using as metabolic parameters the following serum: glucose, amilase, high density lipoprotein cholesterol, free fatty acids. The results indicated that both drugs were potentially similar in relation to glycemia, high density lipoprotein cholesterol, and free fatty acids, in both sexes. Chlorpropamide was significantly more effective in reducing amilase activity in male diabetics than glibenclamide. The above mentioned hypoglycemiants did not reduce glycemia to basic levels in either masculine or feminine groups of diabetics.

Antropologia da doenca e do doente: percepcoes e estrategias de vida dos tuberculosis.

The article examines how tuberculosis patients who were exiled to sanitarium-cities in the state of Sao Paulo reacted to the social representations assigned to them not only by the public at large but by medical workers as well. By evaluating memoirs and related documents from the perspective of the anthropology of disease and the diseased, it was possible to identify the network of signifieds created by the afflicted community.

Posicionamento por ponto de alta precisão utilizando o GPS: Uma solução para a geodinâmica

Point positioning from GPS data can provide precision varying from 100 meters to a few millimeters at the level of 95% probability. To reach the best level of accuracy, users need proper equipment and software, as well as access capability to GPS products available at the International GPS Geodynamics Service. In this paper, the theory related to point positioning using GPS is presented as well as the results of an experiment conducted using data from the Brazilian Active Control System. The results show repeatability better than 5mm and 10mm for the N and E baseline components respectively, and 6mm + 4ppb (parts per billion) for the vertical. Comparison with SIRGAS campaign showed results at the same level of uncertainty as that of the stations used to tie the SIRGAS frame to ITRF94. Therefore, precise point positioning is a powerful tool to be used in applications requiring high level of precision, such as Geodynamics.

Associação entre o achado de cárdia incompetente à endoscopia digestiva alta e presença de esofagite de refluxo

Incompetent cardia (IC) or loose cardia is not uncommon at endoscopic examination but its meaning is not clear. Such incompetence could facilitate gastroesophageal reflux and the appearance of esophagitis as a consequence. The aim of this study is to investigate if there is an association between IC and reflux esophagitis (RE). A review was made of 395 consecutive endoscopic reports of adult males and females performed at the Botucatu Clinics Hospital, of the Unesp - University of the State of São Paulo. Diagnosis of IC is defined by the endoscopic image in which the cardia is partially opened and/or involves the endoscope in a loose manner. Esophagitis characterization was based in the Los Angeles classification. The statistical analysis showed a significant association between CI and RE (p < 0.0001). Although there is not a clear explanation for this association, some hypotheses could be suggested involving hypotonic LES, diaphragmatic crura ineffectiveness and TLESR disorders as conditions able not only to keep the cardia relaxed but also to the reflux followed by esophagitis.

Indicadores de floresta urbana a partir de imagens aéreas multiespectrais de alta resolução

The present work evaluated urban forest indicators, acquired through airborne high-resolution multiespectral images, on the quality of the urban design and its vegetative fraction, in special its trees, in nine neighborhoods of Piracicaba, SP. There were made supervised classifications for characterization of intra-urban elements and the proportions obtained, as exposed soil, tree cover, lawns, asphalt, concrete pavements and roofs. They were studied for the measurement of the urban forest in each place. These variables were related to each other, as well as with the independent variables: population density, people with more than fifteen years of study and family heads with income above twenty minimum wages, obtained through population census. Through the analysis of linear regression variables were identified for intra-urban areas evaluation. Correlations were made and linear regressions among the data obtained from the image and among the proposed indicators. Negative correlations were obtained among population density and arboreal covering and the evaluated indices, in accordance with the predicted in the literature. Composite indicators are proposed, as: the proportion between arboreous space on waterproof space (PAW) and the proportion between arboreous space on building space (PAB). It is concluded by the possibility of the use of those indicators for evaluation of the urban forest and definition of priorities in the execution of ordinances to the improvement of the urban forestry, being prioritized the application of resources in the most lacking neighborhoods.

Parâmetros fisiológicos do desempenho de cavalos de alta performance hidratados voluntariamente com água ou solução isotônica contendo carboidrato

During eight weeks, in summer, four endurance trained high performance horses were worked in resistence exercise, recieving two different types of hydratatio, water or an isotonic solution containing carbohydrates, with the objective to compare their performance physiological parameters. Only the RT (rectal temperature), HR (heart rate), RR (respiratory rate), weight, total protein, glucose, the electrolytes K, Ca and the muscular enzyme CK presented distance effect. The others parameters evaluated, there weren't any identified effects of treatment and of the interaction between distance and treatments, with a significancy level of 5%, and it was concluded that the isotonic solution containing carbohydrate didn't have any significant influence on the animal's performance when compared to water.

Exame eletrocardiográfico em equinos da raça puro sangue Árabe submetidos ao exercício em esteira de alta velocidade e à suplementação com vitamina E

The effect of physical exercise, training and vitamin E supplementation on electrocardiographic parameters was evaluated in eight untrained Arabian mares, divided into two groups: control (n=4) and supplemented with vitamin E (n=4) at the daily dose of 1.000 UI. Animals were submitted to an incremental exercise test (P1) on high-speed treadmill inclined +7%, after that to a training period of 20 days and later to a new incremental exercise test (P2). Analysis and interpretation of electrocardiographic tracings were performed regarding the rhythm, heart rate, duration and amplitude of waves and intervals, before, immediately after and 30 min after the incremental exercise. A reduction of the rest heart rate was observed after training. There was no effect of vitamin E supplementation on electrocardiographic parameters. Results indicated that the electrocardiogram was efficient in detention of cardiac alterations promoted by the physical exercise, but more studies are needed to elucidate its clinical meaning.

Estudio digital radiográfico y densitométrico en mandíbulas de cerdos sometidos a osteotomía con alta y baja velocidad, con refrigeración líquida

The influence of the type of rotary cutting instrument on bone repair after osteotomy in swine jaw, was evaluated using digital and densitometric radiographic examinations, at controlled times. Two cross-sectional dissections were made through the base of the right jaw, one using a high speed rotary instrument and the other using low speed, both with liquid cooling. After established periods the animals were sacrificed and their jaws removed for direct and indirect digital radiographic and densitometric studies using the CROMOX, DIGORA and ODR systems. In the initial periods (7 and 28 days) the bone density was higher in osteotomy areas performed with high rotation speeds, and in the final periods (60 and 90 days) the bone density was higher in the osteotomies performed with low rotation, indicating a better final bone repair with the use of low rotation. The qualitative analysis of the repair process was made by the ODR system which obtained three-dimensional and coloured digital images, which enable the bone thickness to be measured using an aluminium wedge. This showed that by twenty-eight days the bone repair was already apparently complete. © 2010 SECOM.

La suplementación pre-ejercicio con carbohidrato de alta concentración perjudica el rendimiento en el ejercicio de alta intensidad en bicicleta

Objectives. To evaluate the effects of pre-exercise high concentration carbohydrate supplementation on performance, cardiovascular, metabolic and hormonal responses during high intensity cycling exercise. Method. Seven male cyclists (28.7 ± 5.4 years; 65.2 ± 4.7 kg body weight), who performed two continuous exercise trials under placebo (PLA) or carbohydrate (CHO) ingestion at a work rate of 80% VO 2max until exhaustion, participated in the study. The cyclists received 5 ml.kg-1 of a maltodextrin solution diluted at a concentration of 10% (CHO) or placebo (PLA) at 60, 45 and 30 min pre-exercise. Results. A 5.4% reduction in the time to exhaustion was observed in the CHO trial compared to the PLA trial. In both trials, glucose and lactate levels were higher in the post-trial condition compared to pre-exercise values (p < 0.05). Free fatty acid levels were lower in the CHO group than in the PLA group both before and after the trial (p < 0.05). Insulinemia was higher during the pre-trial in the CHO group (42.7 ± 3.6 μU.ml-1) compared to the PLA condition (11.8 ± 3.3 μU.ml-1) (p < 0.05), and even decreased to 23.8 ± 5.1 μU.ml-1 during exercise after CHO intake (p < 0.05). No significant differences in plasma cortisol were observed between the two trials (p > 0.05). Conclusions. Pre-exercise high concentration CHO supplementation resulted in impaired performance in high intensity cycling exercise and decreased free fatty acid levels. © 2010 Revista Andaluza de Medicina del Deporte.

Razão triglicérides/HDL-C e proteína C reativa de alta sensibilidade na avaliação do risco cardiovascular

Introduction: Calculated indexes from laboratory measurements and the determination of plasma markers are commonly used in cardiovascular risk assessment. Objective: To use triglycerides/high-density lipoprotein cholesterol (HDL-C) ratio, estimate of low-density lipoprotein (LDL) particle size and high sensitive C-reactive protein (hs-CRP) levels to the clinical and laboratorial assessment of coronary risk among patients with coronary disease. Material and methods: Sixty patients were chosen accordingly, 36 female (F) (65 ± 9 years of age) and 24 male (M) (55 ± 10 years of age) diagnosed with stable ischemic cardiopathy at Ana Neri Hospital, Salvador, Bahia, Brazil. The investigation was carried out at the Clinical Biochemistry Laboratory of the College of Pharmacy at Federal University of Bahia (UFBA). Blood samples were collected after a 12-hour fast to determine hs-CRP, lipid profile and risk indicators. All data were assessed through Syncron LX®20 Beckman Coulter. The inferential analysis results were considered significant when p ≤ 5%. Data analysis was carried out with GraphPad Prism® (4.03 version) software. Results: Data analysis showed a positive correlation between hs-CRP and triglycerides/HDL-C ratio only among women (r = 0.4; p = 0.0442), n = 36. The analysis of other parameters did not show any significance. Conclusion: The triglycerides/HDL-C ratio and hs-CRP may be used as indicators of increase in cardiovascular risk among women with coronary artery disease (CAD).

Estudio histológico comparativo de la reparación ósea entre hueso alveolar y extra-alveolar en los cerdos sometidos a osteotomía con alta y baja velocidad, con refrigeración líquida

Taking into account the bone repair process in pigs has shown a greater similarity among the histological variables studied compared to other biological models, the present study has as its aim to evaluate the histological bone repair process of osteotomy performed on alveolar and extra-alveolar bones, using drilling tools with liquid refrigeration. Material and method: Eighteen Large White pigs weighing between 20 and 25 Kg were divided into three groups of six animals in order to evaluate the osteotomy repairs with low and high speed in the alveolar bone and threes in the extra-alveolar area, study periods of 7, 14 and 28 days. Results: It was observed that in the alveolar bone at the postoperative times of 14 and 28 days, the best repair results were in the osteotomy performed with low speed, while in the 7 day postoperative period, the results with high speed were slightly better, in alveolar areas as well as extra-alveolar areas. There no statistically significant differences between the alveolar and extra-alveolar bone repair process. Conclusions: The repair process, by means of microscopic analysis in the alveolar and extra-alveolar areas, are similar with better results observed in osteotomies performed with low speed drills in the 14 and 28 day study periods, and at 7 days postoperative the results with high speed drills and refrigeration were slightly better. Research works using pigs as an animal model are perfectly viable. © 2011 SECOM.

Aspectos Históricos e organizacionais da agricultura familiar no desenvolvimento da região Nova Alta Paulista

Nova Alta Paulista region, with strong aptitude for agribusiness, is one of the poorest in the state of São Paulo. However, the development of agribusiness productive chains in the region is very heterogeneous. The study aimed at analyzing how the historical background and organizational arrangements in family farming have contributed to regional development by promoting improvements in social welfare at Nova Alta Paulista region. To this end, we analyzed the case of the Associação Agrícola de Junqueirópolis - AAJ, an organization that has been successful in the search for alternative of agricultural production. Integrated to local and global market, this organization has ensured the maintenance of many farmers and generated positive externalities for the entire region. Thus, this case shows the organizational arrangement based on cooperation can be an alternative for family farmers achieve higher levels of welfare and development.
