ABSTRACT

We present here the first results of Hg concentrations in three small shark species (Rhizoprionodon lalandei, R. porosus and Mustelus higmani) from the SE Brazilian coast. Mercury concentrations in R. lalandei ranged from 21.5 to 280.0 ng.g-1 dry weight (d.w.) (average 74.6 ng.g-1 d.w.; 17.9 ng.g-1 wet weight). In R. porosus, concentrations ranged from 7.6 to 90.5 ng.g-1 d.w. (average 42.2 ng.g-1 d.w., 9.4 ng.g-1 wet weight), whereas in M. higmani, concentrations ranged from 13.0 to 162.8 ng.g-1 d.w. (average 54.9 ng.g-1 d.w., 13.4 ng.g-1 wet weight). These concentration ranges are very low compared with values reported for other large shark species of the Southwestern Atlantic Ocean. There was a significant positive correlation between Hg concentrations and individual size, suggesting that biomagnification is occurring in these animals

ABSTRACT

Se ha comparado la técnica inmunoenzimática (ELISA) "sandwich" indirecta con la prueba de fijación del complemento 50% (FC50) para detectar los serotipos O, A y C del virus de la fiebre aftosa (VFA) y New Jersey (NJ) e Indiana (ND) del virus de la estomatitis vesicular (VEV). Para las cepas O, A e IND se usaron antisueros polivalentes como detectores y para las cepas NJ fueron utilizados antisueros monovalentes. La prueba de ELISA mostró ser un procedimiento más satisfactorio para identificar VFA y VEV en muestras de epitelios de animales afectados por enfermedad vesicular

ABSTRACT

E relatado um caso de sindrome do encarceramento (locked-in-syndrome) em paciente que apresentou quadro subito de tetraplegia,anartria, movimentos oculares verticais e piscar alem de preservacao do nivel de consciencia.Explicacao para tal quadro clinico e uma lesao na ponte junto ou sobre o nucleo do nervo abducente seccionando os tratos cortico-espinal e cortico-bulbar, sem atingir a substancia reticular de mesencefalo. Tres EEG revelaram disturbio projetado por provavel lesao do tronco cerebral, e que foi confirmada pelo CAT SCAN. Arteriografia vertrebral mostrou grau avancado de aterosclerose. Com tratamento clinico conservador o paciente teve otima evolucao
