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.

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.
