13. 1,2 AND 1,4-DICARBOXYLIC COMPOUNDS ACTUATE ON THE GLUTAMATERGIC SYSTEM AND THE BEHAVIOR OF RATS AND MICE / COMPOSTOS 1,2 E 1,4-DICARBOXÍLICOS ATUAM SOBRE O SISTEMA GLUTAMATÉRGICO E O COMPORTAMENTO DE RATOS E CAMUNDONGOS
Glutamatergic receptors are targets for many L-glutamate structure analogues, which cause neurotoxicity. This study investigated the actions of two dicarboxylic compounds, the first had cyclic framework and rigid structure, and the other had an acyclic framework and flexible structure, on the glutamatergic neurotransmission, oxidative damage and behavior in

14. Studies of seizures and actions of nimodipine on pilocarpine-induced seizures in young rats. / Estudo do processo convulsivo e das ações da nimodipina no modelo de convulsão com pilocarpina em ratos jovens
Behavioral and neurochemical studies were carried out with 21 days-old rats pretreated or not with nimodipine (10 or 30mg/Kg, i.p.) on pilocarpine-induced seizures (400mg/Kg, s.c.) to investigate the mechanism involved in the acute phase of seizures and the effects of nimodipine on seizures. The behavioral studies showed peripheral cholinergic signs, stereot

16. Novas molÃculas imidazolidÃnicas: preparaÃÃo, determinaÃÃo estrutural e avaliaÃÃo da atividade anticonvulsivante
Epilepsy, one of the most frequent neurological afflictions in the man, is characterized by recurrent spontaneous seizures by excessive temporary neuronal discharges resulting in uncontrolled convulsion, requires special medical attention. Until moment, the epilepsy remains subtreated the spite of the advances in the development of drugs effective for the tr

18. Evaluation of the central effects of yangambin isolated from Ocotea duckei Vattimo: Behavioral and neurochemical study in mice motor cortex and striatum / Avaliação dos efeitos centrais da iangambina isolada de Ocotea duckei Vattimo: Estudo comportamental e neuroquímico em córtex motor e corpo estriado de camundongo
The effects of the acute administration of yangambin (25, 50 and 75 mg/kg intraperitoneal and oral), were studied in some animals behavioral models (open field, rotarod, forced swimming test, barbiturate-induced sleeping time, hole board, elevated plus maze, pentilenotetrazole-induced convulsion). Binding in vitro with differents concentrations of yangambin

19. Proconvulsant effects of high doses of venlafaxine in pentylenetetrazole-convulsive rats
Venlafaxine, an atypical antidepressant drug, has been used to treat several neurological disorders, presenting excellent efficacy and tolerability. Clinical seizures after venlafaxine treatment have occasionally been reported when the drug was used at very high doses or in combination with other medications. The aim of the present study was to investigate t

20. EFFECTS OF SCORPION Tityus serrulatus VENOM TOXIN TS-8F ON RAT LEARNING AND MEMORY
Scorpion venom neurotoxins are responsible for toxicity and pharmacological effects. They are active in sodium and potassium channels leading to an increase in the release of neurotransmitters, such as glutamate. Glutamate is found in large quantities in the hippocampus (HPC) and is involved in the long-term potentiation (LTP) induction. The HPC is known to

21. Hantaviruses Clinical and serologicalsurvey in Ribeirão Preto, SP / "Estudo clínico-epidemiológico sobre a hantavirose na região de Ribeirão Preto, SP"
The hantaviruses are zoonoses of wild rodents that cause serious human diseases: hemorrhagic fever with renal syndrome in Asia and Europe (10 to 12% lethality rates) and Pulmonary and Cardiovascular Syndrome in the American continent (HPCVS - 59% lethality rate). Hantaviruses (family Bunyaviridae) are enclosing viruses that measure 120 nm approximately, they

22. Convulsive effects of some isolated venom fractions of the Tityus serrulatus scorpion: behavioral, electroencephalographic, and neuropathological aspects
It has been previously shown that the crude venom of Tityus serrulatus can cause convulsions. This study was designed to investigate the neurotoxic effects of B, C, G, and K fractions isolated from this venom. Intravenous injection of these fractions in mice (0.6 - 6.0 mg/kg body weight) showed that the C fraction is a potent convulsant and G fraction decrea

23. Estudo de 34 casos enviados a um grupo de trabalho de epilepsia resistente
The author analysed 34 cases of resistant epilepsy (20 males and 14 females, mean age 23 years), treated clinically between february/1984 and may/1986. The patients underwent neurological, neuropsychological, psychological, psychiatric, cerebrospinalfluid, electroencephalographic, tomographic and/or angiographic examination. Most of the patients had complex

24. Grand mal seizure induced by oral theophylline.
A grand mal convulsion occurred in a patient with decompensated cor pulmonale. Although only modest doses of oral theophylline were being administered at the time of the convulsion the serum theophylline level was markedly raised and the theophylline clearance was very low. After treatment for cor pulmonale theophylline clearance improved; however, with the
