ABSTRACT

O presente trabalho relata o caso de aspergilose sistêmica em um cavalo da raça Quarto de Milha. O animal apresentava quadro de emagrecimento progressivo e alopecia. Os parâmetros avaliados durante o exame clínico encontravam-se de acordo com os valores normais para a espécie. No hemograma verificou-se leucocitose por neutrofilia, sem desvio à esquerda, proteínas plasmáticas totais elevadas e aumento do fibrinogênio, indicando um processo inflamatório acompanhado de desidratação. Os exames bioquímicos séricos demonstraram aumento no valor da ureia. Apesar dos exames realizados e da terapia instituída com antibióticos de amplo espectro e suporte nutricional, após 51 dias de internamento o quadro clínico evoluiu para caquexia e decúbito permanente do paciente, o qual foi submetido à eutanásia seguida de necropsia. Com base nos achados nos exames necroscópico e histopatológico, diagnosticou-se infecção sistêmica por Aspergillus sp., acometendo pulmões, fígado, rins, peritônio parietal e encéfalo. Dentre os fatores predisponentes à relatada infecção fúngica sistêmica, destaca-se o status imunológico debilitado do paciente, possivelmente proporcionado por tratamentos prolongados com antibióticos e anti-inflamatórios esteroidais. O presente trabalho relata o primeiro caso descrito de arpergilose sistêmica no Brasil. O diagnóstico definitivo só foi possível após necropsia e histopatologia, visto que os sinais clínicos inespecíficos não foram determinantes para o diagnóstico em vida.(AU)


This paper reports the case of systemic aspergillosis on a Quarter Horse. The animal had progressive weight loss and alopecia. The parameters evaluated during the clinical examination were in agreement with the normal values for the species. The hemogram showed neutrophilic leukocytosis, without left-sided, elevated total plasma proteins and an increase in fibrinogen, indicating an inflammatory process accompanied by dehydration. Serum biochemical tests showed an increase in the value of urea. Despite the performed tests and established therapy with broad spectrum antibiotics and nutritional support, after 51 days of hospitalization the clinical condition evolved into cachexia and permanent decubitus of the patient which underwent to euthanasia and necropsy. From the findings of necropsy and histopathology, systemic infection was diagnosed by Aspergillus sp., affecting the lungs, liver, kidneys, parietal peritoneum and encephalon. Among the factors predisposing to the reported systemic fungal infection, the patient's weakened immune status is highlighted, possibly due to prolonged antibiotic and steroidal anti-inflammatory treatments. This paper reports the first case described of systemic aspergillosis in Brazil. Definitive diagnosis was only possible after necropsy and histopathology, since nonspecific clinical signs were not determinant for the diagnosis in life.(AU)

ABSTRACT

Objetivou-se investigar se a temperatura de polimerização da resina acrílica odontológica ocasiona sinais neurológicos e alteração histológica na medula espinhal de ratos. Foram utilizados 48 ratos, Wistar, distribuídos em dois grupos denominados GI ou cimento ósseo (controle positivo) e GII ou resina acrílica odontológica. Cada grupo foi redistribuído em seis subgrupos, de acordo com a quantidade do composto, o tempo de pós-operatório e o local de aferição da temperatura. O cimento ósseo ou a resina acrílica odontológica foram moldados e colocados sobre as lâminas ósseas dorsais e os processos espinhosos das vértebras L1 e L2. A temperatura de polimerização do composto foi aferida a cada 10 segundos. A temperatura máxima de polimerização e a diferença entre a temperatura externa e a interna ao canal vertebral foram maiores nos subgrupos que receberam 10 gramas. Não foi observada alteração neurológica em nenhum dos animais deste estudo. Na análise histológica, foi observada reação inflamatória de intensidade variável na meninge e no parênquima medular. Pode-se concluir que a temperatura de polimerização da resina acrílica odontológica nas quantidades de um e 10 gramas provoca alterações histológicas na meninge e no parênquima medular, sem ocasionar sinais neurológicos em ratos.


The purpose of this study was to evaluate if the polymerization temperature of the dental acrylic leads to neurological signs and histological changes in the rat spinal cord. Forty eight rats were distributed in two groups: GI or bone cement (positive control) and GII or dental acrylic resin. Each group was redistributed in six subgroups according to compound quantity, postoperative period and location of temperature measurement. The bone cement or dental acrylic resin were molded and positioned on the bony lamina and the dorsal spinous processes of vertebrae L1 and L2. The polimerization temperature was measured every 10 seconds. The polymerization maximum temperature and the temperature difference between internal and external spinal canals were superior in subgroups that received 10 grams. There were no neurological deficits in any animal of this study. The histological analysis showed intensity variation of inflammatory reaction in the meninges and spinal cord parenchyma. The results demonstrate that the polymerization temperature of dental acrylic resin in quantity of 1 or 10 grams causes histological changes in the spinal cord parenchyma and meninges, without neurological deficits in rats.

ABSTRACT

Due to limited knowledge of Siphonaptera fauna of the Cavia aperea (Brazilian guinea pig) in the State of Rio Grande do Sul, 43 specimens were examined. Six percent of the Brazilian guinea pigs were parasitized with Siphonaptera, which were identified as Polygenis (Neopolygenis) atopus and Polygenis (Polygenis) axius proximus (Rhopalopsyllidae), both with 2.3% of prevalence. P. (Neopolygenis) atopus and P. (Polygenis) axius proximus are reported for the first time on C. aperea in the State of Rio Grande do Sul, Southern Brazil.

ABSTRACT

This study was designed to evaluate the effect of different conditions of collection, transport and storage on the quality of blood samples from normal individuals in terms of the activity of the enzymes Beta-glucuronidase, total hexosaminidase, hexosaminidase A, arylsulfatase A and Beta-galactosidase. The enzyme activities were not affected by the different materials used for collection (plastic syringes or vacuum glass tubes). In the evaluation of different heparin concentrations (10 percent heparin, 5 percent heparin, and heparinized syringe) in the syringes, it was observed that higher doses resulted in an increase of at least 1-fold in the activities of Beta-galactosidase, total hexosaminidase and hexosaminidase A in leukocytes, and Beta-glucuronidase in plasma. When the effects of time and means of transportation were studied, samples that had been kept at room temperature showed higher deterioration with time (72 and 96 h) before processing, and in this case it was impossible to isolate leukocytes from most samples. Comparison of heparin and acid citrate-dextrose (ACD) as anticoagulants revealed that Beta-glucuronidase and hexosaminidase activities in plasma reached levels near the lower normal limits when ACD was used. In conclusion, we observed that heparin should be used as the preferable anticoagulant when measuring these lysosomal enzyme activities, and we recommend that, when transport time is more than 24 h, samples should be shipped by air in a styrofoam box containing wet ice

ABSTRACT

I was studied the histology of Amblyomma tigrinum (Ixodidae) an ixodid fick. Three A. tigrinum engorged females were dissected, collected ovary and tracheae, and fixed in Bouin's aqueous fixative during 24 hours; the organs were cut at a thickness of 6-7 um and stained by hematoxylin-eosin. Ovary of A. tigrinum (Fig. 1) showed two cellular layers, similar to the ovary of D. andersoni and B. microplus, being one outer (oocyts) and the inner layer (epithelial cells). Trachea (Fig. 2) showed a cellular layer and a chitions spiral, similar to D. andersoni

ABSTRACT

Foram estudados 24 caes mesticos, com pesos variaveis entre 13 e 14 kg, distribuidos nos seguintes grupos: Grupo I - oito caes submetidos a derivacao intercarotidea, com interposicao de segmento de veia safena. Grupo II - oito caes submetidos a anastomose entre arteria mamaria interna esquerda e arteria coronaria descendente anterior. Grupo III - oito caes com anastomose venovenosa. Em todos os grupos, 0,8 a 1,5 watts de Laser de Argonio foram aplicados durante tempo total de 90 a 300 segundos. A menor intensidade para as anastomoses venosas e a maior para as arterias. No pos-operatorio imediato as anastomoses com Laser mostraram resistencia pressorica media de 730 mmHg. Apos 30 dias de seguimento a resistencia foi superior a 2.500 mmHg. Os estudos anatomo-patologicos e angiograficos revelaram sempre anastomoses pervias e ausencia de fenomenos tromboticos
