    • Análise dos efeitos do extrato padronizado de Ginkgo biloba L. na aquisição e na extinção do medo condicionado 

      Zamberlam, Claudia Raquel [UNIFESP] (Universidade Federal de São Paulo, 2013-04-25)
      Dados anteriores no nosso laboratório mostraram que os tratamentos a curto ou a longo prazo com o extrato padronizado de Ginkgo biloba L. (EGb) modulam a aquisição da Resposta Emocional Condicionda (REC). Essas modificações ...

    • Anticonvulsant and GABA uptake inhibition properties of venom fractions from the spiders Parawixia bistriata and Scaptocosa raptoria 

      Rodrigues, Marcelo Cairrão Araujo; Ribeiro, Alessandra Mussi; Pizzo, Andrea Baldocchi; Fontana, Andreia Cristina Karklin; Beleboni, Renê de Oliveira; Coutinho-Netto, Joaquim; Miranda, Antonio de [UNIFESP]; Santos, Wagner Ferreira dos (Swets Zeitlinger Publishers, 2002-09-01)
      In this article we describe an in vivo anticonvulsant effect from denatured crude venom and partially isolated fractions from two spiders: Parawixia bistriata and Scaptocosa raptoria. Intracerebroventricular injections of ...

    • Cardiovascular responses to microinjections of GABA or anesthetics into the rostral ventrolateral medulla of conscious and anesthetized rats 

      Lacerda, J.e.c. [UNIFESP]; Campos, Ruy Ribeiro [UNIFESP]; Araujo, G.c. [UNIFESP]; Andreatta-van Leyen, S. [UNIFESP]; Lopes, Oswaldo Ubriaco [UNIFESP]; Guertzenstein, P.g. [UNIFESP] (Associação Brasileira de Divulgação Científica, 2003-09-01)
      The rostral ventrolateral medulla (RVLM) contains neurons involved in tonic and reflex control of arterial pressure. We describe the effects of gamma-aminobutyric acid (GABA) and anesthetics injected into the RVLM of ...

    • Cerebrospinal fluid GABA levels in chronic migraine with and without depression 

      Vieira, DSS; Naffah-Mazacoratti, M. G.; Zukerman, E.; Soares, CAS; Alonso, E. O.; Faulhaber, MHW; Cavalheiro, E. A.; Peres, MFP (Elsevier B.V., 2006-05-23)
      Psychiatric comorbidity is one of the key elements in chronic migraine (CM) management. Depression is particularly common in these patients, occurring in up to 85%. Preclinical studies have suggested that gamma-aminobutyric ...

    • Changes in GABAergic inputs in the paraventricular nucleus maintain sympathetic vasomotor tone in chronic heart failure 

      Carillo, Bruno de Arruda [UNIFESP]; Oliveira-Sales, Elizabeth Barbosa de [UNIFESP]; Andersen, Monica Levy [UNIFESP]; Tufik, Sergio [UNIFESP]; Hipólide, Débora Cristina [UNIFESP]; Santos, A. A. [UNIFESP]; Tucci, Paulo José Ferreira [UNIFESP]; Bergamaschi, Cassia Toledo [UNIFESP]; Campos, Ruy Ribeiro [UNIFESP] (Elsevier B.V., 2012-11-02)
      The paraventricular nucleus (PVN) of the hypothalamus is an important region of the brain involved in the regulation of sympathetic vasomotor tone. Accumulating evidence supports the idea that a change in hypothalamic ...

    • DECREASED SUSCEPTIBILITY TO SEIZURES INDUCED BY BICUCULLINE AFTER TRANSIENT BILATERAL CLAMPING of the CAROTID ARTERIES in RATS 

      Sieklucka, M.; Bortolotto, Z.; Heim, C.; Block, F.; Sontag, K. H. (Springer, 1991-01-01)
      Rats were exposed for 24 min to bilateral clamping of the common carotid arteries (BCCA) in pentobarbital anaesthesia. 14 days later the animals were subjected to subcutaneous injection of (+)-bicuculline (3 or 4 mg/kg). ...

    • Effects of baclofen on reserpine-induced vacuous chewing movements in mice 

      Castro, JPMV; Frussa-Filho, R.; Fukushiro, D. F.; Silva, R. H.; Medrano, W. A.; Ribeiro, R. D.; Abilio, V. C. (Elsevier B.V., 2006-02-15)
      We have described that GABA mimetic drugs present the ability to inhibit the expression of reserpine-induced oral movements. in this respect, oral movements is associated with important neuropathologies. This study ...

    • EFFECTS of BILATERAL CLAMPING of CAROTID ARTERIES ON HIPPOCAMPAL KINDLING in RATS 

      Bortolotto, Z. A.; Heim, C.; Sieklucka, M.; Block, F.; Sontag, K. H.; Cavalheiro, E. A. (Elsevier B.V., 1991-04-01)
      Moderate reduction of cerebral blood flow by bilateral clamping of carotid arteries (BCCA) in pentobarbital anaesthetized Wistar rats induces decreased PO2 and temperature values in vulnerable brain structures such as ...

    • Effects of gabaergic drugs on reserpine-induced oral dyskinesia 

      Peixoto, M. R.; Araujo, N. P.; Silva, R. H.; Castro, JPMV; Fukushiro, D. F.; Faria, R. R.; Zanier-Gomes, P. H.; Medrano, W. A.; Frussa-Filho, R.; Abilio, V. C. (Elsevier B.V., 2005-05-07)
      Recently we have described the antidyskinetic property of the GABA mimetic drugs valproic acid and topiramate on reserpine-induced oral dyskinesia. in this respect, oral dyskinesia has been associated with important ...
