1. Meningoencephalitis due to Naegleria fowleri in cattle in southern Brazil
Resumo Naegleria fowleri é uma ameba de vida livre, comumente encontrada no meio ambiente, principalmente em água doce e no solo. Este protozoário é ocasionalmente associado a casos fatais de doença do sistema nervoso central em seres humanos e espécies animais. No presente trabalho, um caso de meningoencefalite por Naegleria fowleri em um bovino na re

2. Comparative gross encephalon morphology in Callichthyidae (Teleostei: Ostariophysi: Siluriformes)
RESUMO Callichthyidae é composto por Callichthyinae e Corydoradinae, ambos morfologicamente distintos e monofiléticos. Apesar do consenso em relação ao mofiletismo da família, as relações de cerca de 80% de suas espécies, atualmente incluídas no gênero Corydoras, permanecem pouco conhecidas. Apesar da grande quantidade de informação osteológica

3. Astrocytic expression of GFAP and serum levels of IL-1β and TNF-α in rats treated with different pain relievers
ABSTRACT Pro-inflammatory cytokines and glial cells, especially microglial cells, have been implicated in persistent pain sensitization. Less is known about the role of astrocytes in pain regulation. This study aimed to observe the expression of the astrocytic biomarker glial fibrillary acidic protein (GFAP) and the serum levels of interleukin 1 beta (IL-1β

4. Raiva em equino no município de Porto Alegre - RS, Brasil = Equine rabies in the city of Porto Alegre - RS, Brazil / Equine rabies in the city of Porto Alegre - RS, Brazil
Background: rabies is a fatal zoonosis caused by a highly neurotropic RNA virus which causes neurological signs and that is distributed almost worldwide. Rabies affects domestic and wild animals and this is a disease transmitted by their bites, through which the virus present in the saliva is inoculated. In Brazil, Desmodus rotundus is the main hematophagous

5. POLIOENCEFALOMALACIA EM RUMINANTES / POLIOENCEPHALOMALACIA IN RUMINANTS
In the first portion of this thesis, epidemiology, clinical signs and distribution of lesions in the brain of thirty one cases of polioencephalomalacia (PEM) in cattle from the Southern (13 cases) and Midwestern (18 cases) Brazil were studied. Morbidity (0.04%-6.66 %), mortality (0.04%-6.66 %), and lethality (50%-100%) rates were similar in both regions stud

6. NEUROPATOLOGIA DA CINOMOSE CANINA / NEUROPATHOLOGY OF CANINE DISTEMPER
Canine distemper is one of the most prevalent viral diseases of dogs. Several cases are diagnosed in a daily basis in private practices and veterinary hospitals around the country. Most cases of neurological manifestation of canine distemper are fatal and the diagnosis confirmation by histopathology is often necessary. Canine distemper encephalitis is the ma

7. Chlorpheniramine facilitates inhibitory avoidance in teleosts submitted to telencephalic ablation
The present study investigated the involvement of H(1) histaminegic receptor on the acquisition of inhibitory avoidance in Carassius auratus submitted to telencephalic ablation. The fish were submitted to telencephalic ablation 5 days before the experiment. The inhibitory avoidance procedure included 1 day for habituation, 3 days for training composed of 3 t

8. Desenvolvimento embriológico e fetal em pacas (Agouti paca, Linnaeus 1766): estabelecimento de modelo experimental análogo murino para detecção de linhagens "Germ Cells" / Development of embryonic and fetal of pacas (Agouti paca, Linnaeus 1766): establishment of experimental model analogous to murine "Germ cells" linage detection
The study aimed elucidates the development of embryonic and fetal of pacas (Agouti paca) and demarcation of the germ sites in embryos at different stages. Seven specimens were used; two embryos and three fetuses from UNESP- Jaboticabal and other two fetuses were from FMVZ-USP collection. The fetuses 1 and 2 showed immaturity facial sharp, eyes covered by a l

9. Estudo da distribuição da proteína S100b em encéfalo de ratos. / Distribution of the S100b protein specific in brain of the rats.
S100b protein is expressed primarily by astroglia in the brain, and practice functional implication of S100b secretion by astrocytes into the extracellular space is scant but there is substantial evidence that secreted glial S100b exerts trophic or toxic effects depending on its concentration. We pr

10. Anatomical study of the brain stem of the Cebus apella monkey / Estudo anatômico do tronco encefálico do macaco Cebus apella
Os macacos Cebus apella são hábeis com suas mãos e capazes de utilizar ferrementas (paus e pedras) para resolver problemas, podendo ser treinados como assistentes de pessoas quadriplégicas. São escassas ainda as informações em neuroanatomia desses primatas, o que motiva a presente pesquisa, cujo propósito é o de enfocar a morfologia externa e intern

11. Frequent occurrence of nicotinic acetylcholine receptors in GABAergic neurons of the chick visual system
Double-labeling immunohistochemical methods were used to investigate the occurrence of the alpha8 and alpha5 nicotinic receptor subunits in presumptive GABAergic neurons of the chick nervous system. Nicotinic receptor immunoreactivity was often found in cells exhibiting GABA-like immunoreactivity, especially in the visual system. The alpha8 subunit appeared

12. Mesencephalic stimulation elicits inhibition of phrenic nerve activity in cat.
1. Previous work from this laboratory has indicated that the mesencephalon is the anatomical substrate for a mechanism capable of inhibiting central respiratory drive in glomectomized cats for periods of up to 1 h or more following brief exposure to systemic hypoxia; phrenic nerve activity was used as an index of central respiratory drive. 2. The present stu
