Resumo: | The consumption of processed foods that are rich in saturated and trans fat acids can modify the phospholipidic composition of the neural membranes. Thus, altering their plasticity and neurotransmission, the fatty acids (FA) that compose these membranes come from the diet, especially during the brain development period. Studies has shown that chronic consumption of trans fat during the early stages of life may facilitate the development of addiction to psychostimulant drugs. On the other hand, the gender, which has already shown the differences in behavioral and neurochemical response to addictive drugs, also has an influence on the development of addiction, although, the data are controversy. In the last years, addition to opioids has become a serious public health problem, since the number of addicted people and overdose deaths have grown alarmingly. The objective of this study was to evaluate the influence of maternal intake of hydrogenated vegetable fat (HVF) rich in trans FA during gestation and lactation on parameters of anxiety and morphine addiction (4 mg/kg), a recognized opioid of clinical use, in adolescent male and female pups. In addition, the generation of reactive species (RS) in brain areas involved with addiction was evaluated. The results showed that females of the HVF group showed higher preference to morphine and less anxiety behavior when compared to males of the same experimental group. Also, was observed that supplementation with HVF in both sexes increased per se the generation of RS in the ventral tegmental area (VTA), whereas administration of morphine did not modify this oxidative parameter. After administration to morphine, only females of the HVF group showed increased levels of RS in the hippocampus when compared to males. From these results, we can suggest that the gender can be considered a predisposing factor for the opioid addiction development, given that females showed a higher preference for the drug. Moreover, maternal trans fat consumption in the pups' developmental periods also modified parameters to morphine addiction, possibly due to the incorporation of trans FA in the phospholipids of the brain neural membranes, affecting the opioid system and oxidative status of brain areas related to addiction. |

Estudos têm mostrado que o consumo crônico de gordura trans durante as fases iniciais da vida pode facilitar o desenvolvimento de adição à drogas psicoestimulantes. Por outro lado, o gênero, que já mostrou diferenças nas respostas comportamentais e neuroquímicas frente à drogas aditivas, também têm mostrado alguma influência sobre o desenvolvimento de adição, porém os dados mostram controvérsias. Nos últimos anos, a adição a opioides têm se tornado um grave problema de saúde pública, já que o número de adictos e de mortes por overdose têm crescido de forma alarmante. O objetivo deste estudo foi avaliar a influência da ingestão materna de gordura vegetal hidrogenada (GVH), rica em AG trans, durante os períodos de gestação e lactação sobre parâmetros de ansiedade e de adição à morfina (4 mg/kg), um reconhecido opioide de uso clínico, nos filhotes de ratos machos e fêmeas adolescentes. Também, avaliou-se a geração de espécies reativas (ER) em áreas cerebrais envolvidas na adição. Os resultados obtidos mostraram que as fêmeas do grupo GVH apresentaram maior preferência por morfina e menor comportamento de ansiedade, quando comparadas aos machos do mesmo grupo experimental. Além disso, observou-se que a suplementação de GVH em ambos os sexos aumentou per se a geração de ER na área tegmental ventral (ATV), enquanto que a administração da morfina não modificou este parâmetro oxidativo. Após a administração de morfina, somente as fêmeas do grupo GVH apresentaram níveis aumentados de ER no hipocampo, quando comparadas aos machos. A partir destes resultados, podemos sugerir que o gênero pode ser considerado um fator de predisposição para o desenvolvimento de adição à opioides, visto que as fêmeas mostraram maior preferência pela droga. Além disso, o consumo materno de gordura trans nos períodos de desenvolvimento dos filhotes também modificou os parâmetros de adição à morfina, possivelmente devido a incorporação de AG trans nos fosfolipídios das membranas neurais do cérebro, afetando o sistema opioide e o status oxidativo em áreas cerebrais relacionadas à adição.Universidade Federal de Santa MariaBrasilFarmacologiaUFSMPrograma de Pós-Graduação em FarmacologiaCentro de Ciências da SaúdeBurger, Marilise Escobarhttp://lattes.cnpq.br/9128090974948413Bortolatto, Cristiani Folharinihttp://lattes.cnpq.br/8879481124489885Rubin, Maribel Antonellohttp://lattes.cnpq.br/7237734243628134Roversi, Karine2019-09-04T20:20:44Z2019-09-04T20:20:44Z2017-02-17info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://repositorio.ufsm.br/handle/1/18141ark:/26339/001300000h60wporAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSM2019-09-05T06:01:27Zoai:repositorio.ufsm.br:1/18141Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2019-09-05T06:01:27Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
