ABSTRACT
Caracterizou-se filogeneticamente o vírus da raiva, isolado de morcegos hematógafos (Demodus rotundus). Cento e noventa e nove D. rotundus foram capturados em cinco abrigos, no Norte e Noroeste do Estado do Rio de Janeiro e sul do Espírito Santo. Sete deles foram positivos para a raiva. Amostras desses vírus foram sequenciadas e comparadas com sequências provenientes de diversos estados brasileiros. As sequências de vírus da raiva isoladas, na região norte do Estado do Rio de Janeiro, mostraram características que as distinguem de amostras de vírus isoladas em outras regiões do país, no entanto foram idênticas às isoladas de bovinos no noroeste do Rio de Janeiro.
Rabies samples isolated from vampire bats captured in the Rio de Janeiro State were phylogenetically analyzed. One hundred and ninety nine vampire bats were captured from five shelters from North and Northwest of Rio de Janeiro and South of Espírito Santo States. Seven of them were positive for rabies. Theses samples were sequenced and compared with rabies virus sequences from several Brazilian states. The sequences of rabies virus, isolated in the present work, from North of Rio de Janeiro State, showed characteristics that differ of the sequences isolated from bats from other Brazilian regions. However, they were identical to samples isolated from cattle in Northwest of Rio de Janeiro state.

Dyed polymethylmethacrylate (PMMA) detectors using yellow, red, blue and green colouring compounds, commercially available in Brazil, were originally developed and characterised using the optical absorption (OA) technique for gamma radiation, with the aim of obtaining a sensitive, useful, practical and cheap dosemeter for use in the quality control of industrial gamma radiation processing. In this work these detectors were evaluated for electron OA response, for use in the quality control of electron accelerator radiation processing. The studied parameters were the absorption spectra, dose-rate dependence between 2.66 and 45.22 kGy s(-1); dose response between 1.2 and 110 kGy; and energy dependence of response between 0.8 and 1.5 MeV electron energy.

Se estudiaron por medio de ecodoppler color 40 hombres impotentes, con factores de riesgo vascular como antecedentes de su disfunción eréctil. El estudio fue realizado con el pene en estado de flaccidez en escala de grises para la detección de anomalías estructurales, y postinyección de drogas vasoactivas (Alprostadil 10 microgramos) a los 5,15 y 25 minutos. En todos los casos fueron medidas las velocidades de pico sistólico, velocidades de fin de diástole y el calibre arterial. La medición fue hecha sobre la artyeria cavernosa derecha o izquierda, tomando en cuenta el mejor resultado. Observamos que en estado de flaccidez no se pueden obtener datos suficientes para establecer un diagnóstico correcto. En cambio, a los 15 minutos obtuvimos datos suficientes para determinar patrones morfológicos y hemodinámicos de la arteria cavernosa como para realizar diagnóstico de impotencia vasculogénica
