Resumo: | Treatment with neuroleptic drugs has been associated to side effects like tardive diskynesia and hepatic damage. In spite of the several reports of hepatotoxicity after neuroleptic administration, few data are available in the literature about these effects and the precise mechanisms by which neuroleptics induce hepatotoxicity remain unclear. In the same way, there are few studies about the effects of neuroleptics on kidney. In this way, the first aim of the present work was to assess the effects of chronic exposure to fluphenazine in liver and kidney of rats, as well as the protective effect of diphenyl diselenide on the fluphenazine-induced damage (article 1). Long-term treatment with fluphenazine caused an increase in lipid peroxidation levels in liver and kidney homogenates, a decrease in hepatic SOD activity, and an increase in hepatic CAT activity. Diphenyl diselenide was able to protect liver and kidney from lipid peroxidation, ameliorate SOD activity in liver, and prevent the increase in hepatic CAT activity. Diphenyl diselenide treatment did not affect δ-ALA-D activity, but fluphenazine and/or in combination with diphenyl diselenide showed an inhibitory effect on δ-ALA-D activity in liver and kidney. The second objective of this study was to determine whether the treatment with haloperidol (HP), valerian or both in association impairs liver or kidney functions (article 2). Valerian did not affect oxidative stress parameters in the liver or kidney of rats. HP only increased glutathione (GSH) depletion in liver, but not in kidney. However, when HP was associated with valerian, an increase in lipid peroxidation levels and reactive species production was observed in the hepatic tissue. HP and valerian when administered independently did not affect the activity of hepatic and renal δ-ALA-D, however, these drugs administered concomitantly provoked an inhibition of hepatic δ-ALA-D activity. Serum aspartate aminotransferase (AST) activity was not altered by any treatment. However, serum alanine aminotransferase (ALT) activity was higher in the HP group and HP plus valerian group. Taken together, these results indicate the relationship between the treatment with flufenazine and the oxidative stress, and also point to the protective role of diphenyl diselenide on the oxidative damage induced by fluphenazine in liver. Our data also suggest adverse interactions between haloperidol and valerian treatments causing hepatic damage related to oxidative stress. |

Apesar dos inúmeros casos de hepatotoxicidade após a administração de neurolépticos, são escassos os dados na literatura a respeito desses efeitos e o mecanismo exato pelo qual neurolépticos induzem hepatotoxicidade permanece incerto. Da mesma forma, existem poucos estudos relatando os efeitos dos neurolépticos sobre o rim. Dessa forma, o primeiro objetivo deste trabalho foi avaliar os efeitos da exposição crônica à flufenazina em fígado e rim de ratos bem como o efeito protetor do disseleneto de difenila sobre o dano induzido por flufenazina (artigo 1). O tratamento prolongado com flufenazina causou um aumento na peroxidação lipídica no fígado e no rim, uma diminuição na atividade da SOD hepática, e um aumento na atividade da CAT hepática. O disseleneto de difenila foi capaz de proteger o fígado e o rim da peroxidação lipídica, melhorou a atividade da SOD no fígado, e preveniu o aumento na atividade da CAT no fígado. O tratamento com disseleneto de difenila não afetou a atividade da δ-ALA-D, mas a flufenazina e/ou em combinação com disseleneto de difenila demonstrou ter efeito inibitório sobre a atividade da δ-ALA-D no fígado e no rim. O segundo objetivo deste estudo foi determinar se o tratamento com haloperidol (HP), valeriana ou a associação de ambas as drogas pode alterar as funções hepáticas e renais (artigo 2). A valeriana não afetou nenhum parâmetro de estresse oxidativo no fígado e no rim dos ratos. O HP apenas aumentou a depleção de glutationa (GSH) no fígado, mas não no rim. Entretanto, quando o HP foi associado com a valeriana, um aumento na peroxidação lipídica e produção de espécies reativas foram observados no tecido hepático. HP e valeriana quando administrados independentemente não afetaram a atividade da δ-ALA-D hepática e renal, contudo, quando estas drogas foram administradas concomitantemente provocaram uma inibição da atividade da δ-ALA-D hepática. A atividade da aspartato aminotransferase (AST) do soro não foi alterada por nenhum dos tratamentos. No entanto, a atividade da alanina aminotransferase (ALT) do soro estava aumentada nos grupos tratados com HP e HP mais flufenazina. Juntos estes resultados indicam uma relação entre o tratamento com flufenazina e o estresse oxidativo, e também apontam para o papel protetor do disseleneto de difenila no dano oxidativo induzido por flufenazina no fígado. Nossos dados também sugerem interações adversas no tratamento com haloperidol e valeriana, ocasionando dano hepático associado ao estresse oxidativo.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica ToxicológicaUFSMBRBioquímicaFlufenazinaSelênioDisseleneto de difenilaHaloperidolValeriana officinalisInteração planta medicinal-fármacoEstresse oxidativoTBARSδ-ALA-DFluphenazineSeleniumDiphenyl diselenideHerb-drug interactionOxidative stressCNPQ::CIENCIAS BIOLOGICAS::BIOQUIMICAAvaliação dos efeitos do tratamento crônico com neurolépticos e sua interação com substâncias potencialmente antioxidantes sobre parâmetros de estresse oxidativo no fígado e rim de ratosAssessment of the effects of chronic treatment with neuroleptics and their interaction with potentially antioxidants substances on oxidative stress parameters in liver and kidney of ratsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisSoares, Félix Alexandre Antuneshttp://lattes.cnpq.br/8752453650114092Rocha, João Batista Teixeira dahttp://lattes.cnpq.br/3935055744673018Burger, Marilise Escobarhttp://lattes.cnpq.br/9128090974948413Ferreira, Julianohttp://lattes.cnpq.br/2694197910478313http://lattes.cnpq.br/5296284169605317Dalla Corte, Cristiane Lenz2008000000024005005005005005003aef53b7-b173-4c56-a944-bed2de5e5dda45678419-a33f-4747-8785-5f9eb4b903fd4a2aa8a7-cae4-4911-ab61-026ad02d65209ba38641-32d0-45d3-92ea-7987f1ae97dab410c4c0-c1c6-41df-aed8-741731a2b8a2info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALCRISTIANEDALLACORTE.pdfapplication/pdf2060123http://repositorio.ufsm.br/bitstream/1/11086/1/CRISTIANEDALLACORTE.pdf2630a85d242d93eb6f49ed288fc4c0a9MD51TEXTCRISTIANEDALLACORTE.pdf.txtCRISTIANEDALLACORTE.pdf.txtExtracted texttext/plain159429http://repositorio.ufsm.br/bitstream/1/11086/2/CRISTIANEDALLACORTE.pdf.txtc19282f1ec8001ee7fd9c9a2486ae232MD52THUMBNAILCRISTIANEDALLACORTE.pdf.jpgCRISTIANEDALLACORTE.pdf.jpgIM Thumbnailimage/jpeg6196http://repositorio.ufsm.br/bitstream/1/11086/3/CRISTIANEDALLACORTE.pdf.jpg517a295853b53a741edb3509e8767a27MD531/110862023-04-18 08:23:01.375oai:repositorio.ufsm.br:1/11086Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132023-04-18T11:23:01Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
