Resumo: | The present study evaluated the effects of 5-fluorouracil (5-FU) administration using a clinical treatment protocol for 14 days on the ileum in healthy Wistar rats. The animals were divided into two groups (n = 6/group): 5-FU-treated group and control group. The 5-FU group received 5-FU (15 mg/kg, i.p.) for 4 consecutive days, followed by a dose reduction to 6 mg/kg for 4 alternating days and then a last maintenance dose of 15 mg/kg on day 14. This treatment protocol is commonly used in the human clinical setting. The control group received saline (i.p.) according to the same treatment protocol. The ileum was then fractionated to evaluate oxidative stress parameters (catalase [CAT], superoxide dismutase [SOD], glutathione-S-transferase [GST], non-protein sulfhydryl groups [GSH], reactive oxygen species [ROS], and lipid hydroperoxide [LOOH]), markers of inflammation (interleukin-1 [IL-1], IL-6, myeloperoxidase [MPO], and N-acetylglucosaminidase [NAG]), and nitrite levels. HuC/D-immunoreactive myenteric neurons, neuronal nitric oxide synthase (nNOS)-immunoreactive nitrergic neurons, and ileum wall morphometry were also analyzed. The 5-FU treatment protocol promoted oxidative stress and altered nitrite levels but did not cause inflammation. The treatment protocol also reduced the density of nitrergic neurons and altered the morphometry of the general HuC/D-positive myenteric neuronal population and nNOS-positive nitrergic neuronal subpopulation. Treatment with the clinical 5-FU treatment protocol promoted grade I mucositis in rats, characterized by oxidative stress and morphological changes in the intestinal wall. |

Los animales se dividieron en dos grupos (n = 6 / grupo): grupo tratado con 5-FU y grupo control. El grupo de 5-FU recibió 5-FU (15 mg / kg, ip) durante 4 días consecutivos, 6 mg / kg durante 4 días alternos, seguida de una última dosis de mantenimiento de 15 mg / kg en el día 14. Este protocolo se usa comúnmente en el entorno clínico humano. El grupo de control recibió solución salina (i.p.) con el mismo protocolo de tratamiento. Fueron evaluados los parámetros de estrés oxidativo (catalasa [CAT], superóxido dismutasa [SOD], glutatión-S-transferasa [GST], grupos sulfhidrilo no proteicos [GSH], especies reactivas de oxígeno [ROS] e hidroperóxido de lípido [LOOH]), marcadores de inflamación (interleucina-1 [IL-1], IL-6, mieloperoxidasa [MPO] y N-acetilglucosaminidasa [NAG]) y niveles de nitrito, se analizaron las neuronas mientéricas inmunorreactivas de HuC / D, las neuronas nitrérgicas inmunorreactivas del óxido nítrico neuronal (nNOS) y la morfometría de la pared del íleon. El tratamiento con 5-FU promovió el estrés oxidativo y alteró los niveles de nitrito, pero no provocó inflamación. Redujo la densidad de neuronas nitrérgicas, alteró la morfometría de la población general de neuronas mientéricas positivas para HuC / D y la subpoblación de neuronas nitrérgicas positivas para nNOS. El tratamiento con un protocolo clínico de 5-FU promovió mucositis grado I en ratas, caracterizada por estrés oxidativo y cambios morfológicos en la pared intestinal.O estudo avaliou os efeitos da administração de 5-fluorouracil (5-FU) pelo protocolo de tratamento clínico por 14 dias no íleo em ratos Wistar saudáveis. Os animais foram divididos em dois grupos (n = 6 / grupo): grupo tratado com 5-FU e grupo controle. O grupo 5-FU recebeu 5-FU (15 mg / kg, ip) por 4 dias consecutivos, com redução da dose para 6 mg / kg por 4 dias alternados, seguido de uma última dose de manutenção de 15 mg / kg no dia 14. Este protocolo é comumente usado no ambiente clínico humano. O grupo controle recebeu solução salina (i.p.) de acordo com o mesmo protocolo de tratamento. O íleo foi fracionado para avaliar os parâmetros de estresse oxidativo (catalase [CAT], superóxido dismutase [SOD], glutationa-S-transferase [GST], grupos sulfidrila não proteicos [GSH], espécies reativas de oxigênio [ROS] e hidroperóxido de lipídio [LOOH]), marcadores de inflamação (interleucina-1 [IL-1], IL-6, mieloperoxidase [MPO] e N-acetilglucosaminidase [NAG]) e níveis de nitrito. Neurônios mioentéricos imunorreativos HuC / D, neurônios nitrérgicos imunorreativos de óxido nítrico neuronal (nNOS) e morfometria da parede do íleo também foram analisados. O tratamento com 5-FU promoveu estresse oxidativo e alterou os níveis de nitrito, mas não causou inflamação. Também reduziu a densidade de neurônios nitrérgicos e alterou a morfometria da população geral de neurônios mioentéricos HuC / D positivo e da subpopulação de neurônios nitrérgicos positivos para nNOS. O tratamento com protocolo clínico de 5-FU promoveu mucosite grau I em ratos, caracterizada por estresse oxidativo e alterações morfológicas na parede intestinal.Research, Society and Development2020-11-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/966110.33448/rsd-v9i11.9661Research, Society and Development; Vol. 9 No. 11; e1529119661Research, Society and Development; Vol. 9 Núm. 11; e1529119661Research, Society and Development; v. 9 n. 11; e15291196612525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/9661/8630Copyright (c) 2020 Lilian Catarim Fabiano; Mariana Conceição da Silva; Karile Cristina da Costa ; Pedro Luiz Zonta de Freitas; Camila Quaglio Neves; Stephanie Carvalho Borges; Ana Cristina Breithaupt-Faloppa; Nilza Cristina Buttowhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFabiano, Lilian Catarim Silva, Mariana Conceição da Costa , Karile Cristina da Freitas, Pedro Luiz Zonta de Neves, Camila Quaglio Borges, Stephanie Carvalho Breithaupt-Faloppa, Ana Cristina Buttow, Nilza Cristina 2020-12-10T23:37:57Zoai:ojs.pkp.sfu.ca:article/9661Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:31:53.159980Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
