Diagnóstico da otite média em cães: comparação entre radiografia convencional, canalografia e audiometria de impedância

Radiography (conventional and contrasted - canalography) and audioelectrophysiologic (impedance audiometry) tests were correlated with otitis media in 12 middle ear affected and 12 healthy dogs. When comparing both diagnostic methods, it was found that the reliability in the detection of otitis media in dogs was 100% for the first and 58.3-60.0% for the latter. Thus, it was possible to attest that the impedance audiometry was the most accurate method in the identification of otitis media in dogs when compared with radiographic assessments

Age influence on quality of shell and penetration in bacterial laying lightweight eggs

ABSTRACT This study evaluated the influence of the bird’s age on the quality of the shell and percentage of bacterial penetration in commercial eggs. White-shelled commercial eggs were used, laid by light laying hens in their first laying cycle at 21, 39, 51, and 62 weeks of age. Shell quality evaluations comprised: egg weight, specific gravity, percentage and thickness of shell, number and size of pores. For evaluations regarding bacterial penetration, strains of several enterobacterias and one salmonella were used, all of which resistant to Nalidixic acid (100µg/ml). The method employed for evaluation of bacterial penetration was filling the eggs with growth medium. The data were subjected to variance analysis with 5% of probability using SAS (Education Analytical Software, 2013). Eveb though increase in the laying hen's age caused reduction of the quality of eggshells, it failed to affect the percentage of penetration of the bacterial samples evaluated

Uso de cetoanálogo na terapia da insuficiência renal canina Use of keto analogues in therapy of the renal failure in dogs

<abstract language="eng">The efficacy of keto acids and essential amino acids on a two-year-old female dog, Labrador, suffering from Leishmaniasis and acute renal failure was evaluated by clinical and laboratorial analyses based on urea and creatinine dosages. An improving in the animal general condition and an increasing in the appetite, activity and weight gain, were observed and favorably contributed to the treatment of the primary disease. Ketoanalogueswere oraly administered during 76 days and the levels of urea and creatinine remained within acceptable limits, even after this period of time. Ketoanaloguescontributed positively for the treatment of acute renal failure and appears to be an important alternative for the leishmaniasis treatment

Técnicas radiográficas intra e extrabucal na avaliação dentária de cães com doença periodontal

Foram avaliadas as técnicas radiográficas dentárias intra (TIB) e extrabucal (TEB) em 50 cães com doença periodontal, no intuito de padronizar os procedimentos de diagnóstico dessa síndrome. A TIB revelou que 16 animais não apresentaram lesões ósseas visíveis, enquanto a TEB apontou que 39 pacientes foram negativos para as mesmas lesões. Em resumo, a TIB foi mais eficaz na detecção de sinais radiográficos, especialmente as chamadas lesões finas, que a TEB, sendo a técnica de escolha na síndrome periodontal

Perfis clínico e hematológico de camundongos submetidos ao envenenamento escorpiônico experimental por Tityus fasciolatus

Estudou-se o quadro clínico do veneno decorrente do envenenamento por Tityus fasciolatus e sua ação refletida nos componentes hematológicos no modelo murino. Para o estudo do perfil hematológico, foram utilizados 54 camundongos Swiss CF1, machos, com 30g, distribuídos em três grupos (G) (n=18) inoculados via subcutânea com: 50µL de PBS (G1); 24µg de veneno de T. fasciolatus (G2) e 8µg de veneno de T. serrulatus (G3). Cada grupo foi subdividido em três subgrupos (n=6) de acordo com o momento da coleta de sangue que foi estipulada em uma, oito e 24h após a inoculação do veneno, e foram realizados o hemograma e a dosagem de proteínas totais e fracionadas. O veneno de T. fasciolatus na dose de 24µg causou piloereção, comportamento nociceptivo, secreção nasal e oral acentuada, dispneia, prurido na face e reflexos exacerbados. No exame hematológico, foram observadas policitemia relativa e leucocitose com linfocitose
