Abstract: trypanosoma evansi caused severe anemia in horses and pronounced leukopenia in dogs, both naturally infected. the horses presented microcytic normochromic anemia and the dogs showed microcytic hypochromic anemia. the clinical signs observed were fever, anemia, edema of the legs and lower parts, weakness and inappetence. light microscopic studies demonstrated that trypanosoma evansi produced several alterations in erythrocytes of dogs and horses. these pathologic changes included vacuolation, acanthocytes, dacrocytes, codocytes, microspherocytes and bizarre shapes. mature erythrocyte were observed adhered to trypanosomes. erythrophagocytosis was also demonstred.

Abstract: objective: the present study was aimed at evaluating by means of magnetic resonance imaging a series of fetuses with sonographic diagnosis of malformation, establishing the diagnostic benefits and limitations of fetal magnetic resonance imaging as compared with ultrasonography. materials and methods: forty women between 15-35 gestational weeks and previously diagnosed with fetal abnormality by ultrasonography were referred to undergo complementary fetal magnetic resonance imaging, particularly for evaluating abnormalities in the fetal central nervous system, thorax, abdomen, renal system, skeletal system, and tumors. the whole evaluation process included a review of the fetal ultrasonography and magnetic resonance images, postnatal follow-up, laboratory tests, imaging studies and necropsy. results: the present study has demonstrated that complementary magnetic resonance imaging did provide further information in 60% of cases, with the following benefits: improved information on the fetus as a whole, with a large field of view, higher anatomic resolution provided by fast sequences, superior soft tissue contrast resolution, besides the fact that the visualization of the fetus is not significantly affected by maternal obesity or oligohydramnios. limitations of the method include contraindication in the first gestational trimester and in cases of maternal claustrophobia, sensitivity to fetal motion, low sensitivity for detecting cardiovascular and skeletal malformations. conclusion: fetal magnetic resonance imaging plays a significant role as a complementary method for the diagnosis of fetal anomalies.

Abstract: O presente trabalho foi realizado em propriedades rurais da empresa Jalles Machado, S/A A úcar e álcool, em Goianésia (GO). Com o objetivo de obter subsídios técnicos para orientar programas de recomposi o de matas ciliares e de áreas de preserva o permanente, foram avaliados a sobrevivência e o desenvolvimento, quanto à altura e o diametro do colo, de espécies de plantas arbóreas nativas e exóticas, conduzidas em ambientes antropizados, com características peculiares. Os dados foram registrados em intervalos de dois meses e meio, diretamente dos indivíduos plotados em 32 áreas amostrais de 400 m2 cada. Os resultados indicaram porcentagens de mortalidade de plantas superiores a 30% para as espécies a aí, barriguda, guapeva, mutamba, abacate, pau-d’óleo, a oita-cavalo, bálsamo, cedro, mogno, chichá, conde e caraíba, menos adaptadas a determinadas situa es ambientais. As espécies goiabeira, sangra-d’água, gameleirinha, jamel o, tamboril-da-mata, ipê-amarelo-do-cerrado, ipê-roxo e monjoleiro apresentaram o melhor desempenho em altura e diametro, nas áreas amostradas cujas características ambientais se aproximavam daquelas exigidas por essas espécies. Como conclus o sugere-se um melhor planejamento quando da sele o das espécies a serem plantadas, procurando distribuí-las segundo sua aptid o natural. PALAVRAS-CHAVE: áreas degradadas; mata ciliar. The present study was carried out on farms of the Jalles Machado, S/A A úcar e álcool, a factory established in Goianésia, Goiás state. In order to obtain technical support for programs of recovering border forests and areas of permanent preservation, survival and development of trees were evaluated. At intervals of two months and a half, heigth and diameter of the stem just above the ground were measured on trees planted in 32 plots of modified environment, 400 m2 each. The results showed high mortality rate of some species less adapted to the environment and good development of others. Therefore planning should include a better choice of tree species well adapted to the environment where they are to be planted. KEY-WORDS: Disturbed lands; gallery forest; environmental.

Abstract: El objetivo de este estudio, paralelo, doble ciego clínico, fue evaluar el efecto de un gel conteniendo extracto de aruera en 10% en la reducción del acúmulo de placa supragingival y gingivitis. Los sujetos de la investigación fueron distribuidos en grupo prueba (n=15 gel aruera) y grupo control (n=15 gel placebo). La cantidad de placa fue evaluada por medio del índice de placa de Turesky-Gilmore-Glickman (IPL), el grado de gingivitis por el índice gingival de L e & Silness (IG) y el grado de inflamación por el índice de sangramiento gingival de Ainamo & Bay (ISG). Los participantes fueron orientados a cepillar los dientes con el gel tres veces al día, por treinta días. Hubo diferencia significativa para los tres índices evaluados en los grupos prueba y control de forma similar pasado los treinta dias. El gel de aruera en 10% asociado al control mecánico de placa no demostró efecto agregado en la reducción de placa bacteriana supragingival ni en gingivitis The aim of this randomized, parallel, double-blind clinical trial was to evaluate the effect of a gel containing 10% of myracrodruon urundeuva extract on the reduction of plaque and gingivitis. Subjects were randomly allocated into either the test group (n=15, test gel) or the control group (n=11, placebo gel). Plaque levels were measured using the Turesky-Gilmore-Glickman index (PLI) and gingivitis was evaluated through Gingival index of L e & Silness (GI) and gingival bleeding index of Ainamo & Bay (GBI). Subjects were asked to brush their teeth with the gel, three times a day, for thirty days. There was a significant difference in all indexes for the both groups in a similar manner after the end of the trial. In conclusion, the gel containing 10% of myracrodruon urundeuva did not showed a additional effect on reduction of plaque and gingivitis
