Avaliação do kit TF-Test para o diagnóstico das infecções por parasitas gastrintestinais em ovinos

This study was performed to standardize parasite egg counting in feces of sheep by TF-Test, in addition to compare this test to the Gordon & Whitlock technique (G&W). Twenty-four lambs were artificially infected with Haemonchus contortus throughout 12 weeks. At the end of this time, faecal samples were taken and animals were slaughtered for worm identification and counting. G&W and TF-Test methods were carried out on each fecal sample. Both tests showed Haemonchus eggs in 95.8% of the samples (P>0.05). The correlation coefficients (r) between fecal egg counts (FEC) using G&W × Total Worm Count (TWC) were r=0.52 (not transformed data) and r=0.85 (transformed data); between FEC by TF-Test × TWC were r=0.51 (not transformed data) and r=0.87 (transformed data). Other 100 fecal samples were taken from naturally infected sheep. In these animals, the G&W and TF-Test methods showed 85% and 86% of fecal samples positive for Strongylidea eggs, respectively (P>0.05). Also in those animals, Eimeria oocysts were found in 33% of fecal samples by TF-Test, whereas in the G&W only 12% were positive (P<0.001). For Strongyloides spp., TF-Test showed 15% of positive fecal samples, whereas G&W showed 5% (P<0.05). In conclusion, both methods were efficient to diagnose gastrointestinal nematodes and TF-Test was superior to diagnose oocysts of Eimeria spp. and eggs of Strongyloides spp; conversely, Strongylidea eggs counting using TF-Test was underestimated.

Síndrome das pernas inquietas: Diagnóstico e tratamento. Opinião de especialistas Brasileiros

This article contains the conclusions of the November 17-18, 2006 meeting of the Brazilian Study Group of Restless Legs Syndrome (GBE-SPI) about diagnosis and management of restless legs syndrome (RLS). RLS is characterized by abnormal sensations mostly but not exclusively in the legs which worsen in the evening and are improved by motion of the affected body part. Its diagnosis is solely based on clinical findings. Therapeutic agents with efficacy supported by Class I studies are dopamine agonists, levodopa and gabapentine. Class II studies support the use of slow release valproic acid, clonazepan and oxycodone. The GBE-SPI recommendations for management of SPI are sleep hygiene, withdrawal of medications capable of worsening the condition, treatment of comorbidities and pharmacological agents. The first choice agents are dopaminergic drugs, second choice are gabapentine or oxycodone, and the third choice are clonazepan or slow release valproic acid.

Diagnóstico da qualidade da água na microbacia do córrego recanto, em americana, no estado de São Paulo

The environmental degradation observed in the Piracicaba, Capivari and Jundiaí watershed has been one of the principal preoccupations of the environmental agencies in the state of São Paulo, Brazil. In this context, there is inserted the Americana county which is cut by streams of unsuitable quality for the human consumption and other uses. The main goal of the present work was evaluated the water quality of the Recanto Creek, affluent of the Quilombo stream, at the Americana county, state of São Paulo, Brazil. The research was developed in the period from March of 2007 to March of 2008, when it was measured the flow and the following physical-chemical water quality parameters: temperature; turbidity; pH; dissolved oxygen (OD); phosphorus (P); ammonia nitrogen (NH 4); nitrate (NO 3); chemical demand of oxygen (DQO), besides total coliforms. The results demonstrated a variation of the flow from 34.3 to 375.2 L s -1, during the evaluated period. The parameters dissolved oxygen, phosphorus, ammonia nitrogen and nitrate presented values out of the limits recommended for rivers of class 3, like the Recanto Creek, suggesting water pollution due to the organic matter disposal.

Diagnóstico das áreas de preservação permanente na bacia hidrográfica do rio Tijuco, Ituiutaba - MG, utilizando tecnologia SIG

The present work had the objective to elaborate the map of land use and vegetation covering from Tijuco river watershed, Ituiutaba-MG, based on digital images obtained by satellite from CBERS 2, through automatic delimitation of permanent preservation areas followed by identification of land use conflict based on the Brazilian Forest Code (Law no 4771/1965) and National Council of Environment's Resolution no 303/02. This paper analyzes, through quantitative parameters and the use of Geographic Information System, the maintenance tracks of width recommended by the legislation for permanent preservation areas over water bodies. The results showed a deficit of conserved areas along the riverbanks of 2334 ha that are not in compliance with the legislation. The pasture occupies unduly 0.97% of the area of the basin in the permanent preservation areas at the riverbanks, while agriculture occupies 0.38%.

Diagnóstico ambiental do rio corumbataí em trecho urbano do município de rio claro, SP

The environmental analysis is an important tool used in forecasting and mitigation of environmental problems. Focusing on the occupation of marginal areas of the Corumbataí River in an urban stretch in the city of Rio Claro (SP), this study aimed to gather information on situations of risk, both to the environment and the population, verified in that area. Through field observation and in specific studies, the geological and geotechnical aspects, the characteristics of surface waters and aspects of urbanization were analyzed. The results show that the environmental problems diagnosed are related to lack of planning in the occupation of the area. Moreover, the natural characteristics of the physical environment expose people to risks such as floods and soil slides.
