Autistic spectrum disorder (ASD) is a group of early-onset neurodevelopmental disorders characterized by impaired social and communication skills. Autism is widely described as a behavioral syndrome with multiple etiologies where may exhibit neurobiological, genetic, and psychological deficits. Studies have indicated that long term use of antibiotics can alter the intestinal flora followed by neuroendocrine changes, leading to behavioral changes. Indeed, previous studies demonstrate that a high dose of amoxicillin can change behavioral parameters in murine animal models. The objective was to evaluate behavioral and oxidative stress parameters in zebrafish exposed to a high dose of amoxicillin for 7 days. Young zebrafish were exposed to a daily concentration of amoxicillin (100 mg/L) for 7 days. Subsequently, the behavioral analysis was performed, and the brain content was dissected for the evaluation of oxidative stress parameters. Zebrafish exposed to a high dose of amoxicillin showed locomotor alteration and decreased social interaction behavior. In addition, besides the significant decrease of sulfhydryl content, there was a marked decrease in catalase activity, as well as an increased superoxide dismutase activity in brain tissue. Thus, through the zebrafish model was possible to note a central effect related to the exposition of amoxicillin, the same as observed in murine models. Further, the present data reinforce the relation of the gut-brain-axis and the use of zebrafish as a useful tool to investigate new therapies for autistic traits.

暴露于高剂量的阿莫西林会导致年轻斑马鱼的行为改变和氧化应激。

自闭症谱系障碍(ASD)是一组以社交和沟通能力受损为特征的早发性神经发育障碍。自闭症被广泛描述为具有多种病因的行为综合征,其中可能表现出神经生物学、遗传和心理缺陷。研究表明,长期使用抗生素会改变肠道菌群,随后神经内分泌发生变化,导致行为改变。事实上,以前的研究表明,高剂量的阿莫西林可以改变小鼠动物模型的行为参数。目的是评估暴露于高剂量阿莫西林 7 天的斑马鱼的行为和氧化应激参数。年轻的斑马鱼暴露于每日浓度的阿莫西林 (100 毫克/升) 7 天。随后,进行了行为分析,并解剖大脑内容以评估氧化应激参数。暴露于高剂量阿莫西林的斑马鱼表现出运动改变和社交互动行为的减少。此外,除了巯基含量显着降低外,过氧化氢酶活性显着降低,脑组织中超氧化物歧化酶活性增加。因此,通过斑马鱼模型可以注意到与阿莫西林的暴露相关的中心效应,与在小鼠模型中观察到的相同。此外,目前的数据加强了肠 - 脑轴与斑马鱼作为研究自闭症特征新疗法的有用工具之间的关系。暴露于高剂量阿莫西林的斑马鱼表现出运动改变和社交互动行为的减少。此外,除了巯基含量显着降低外,过氧化氢酶活性显着降低,脑组织中超氧化物歧化酶活性增加。因此,通过斑马鱼模型可以注意到与阿莫西林的暴露相关的中心效应,与在小鼠模型中观察到的相同。此外,目前的数据加强了肠 - 脑轴与斑马鱼作为研究自闭症特征新疗法的有用工具之间的关系。暴露于高剂量阿莫西林的斑马鱼表现出运动改变和社交互动行为的减少。此外,除了巯基含量显着降低外,过氧化氢酶活性显着降低,脑组织中超氧化物歧化酶活性增加。因此,通过斑马鱼模型可以注意到与阿莫西林的暴露相关的中心效应,与在小鼠模型中观察到的相同。此外,目前的数据加强了肠 - 脑轴与斑马鱼作为研究自闭症特征新疗法的有用工具之间的关系。以及脑组织中超氧化物歧化酶活性的增加。因此,通过斑马鱼模型可以注意到与阿莫西林的暴露相关的中心效应,与在小鼠模型中观察到的相同。此外,目前的数据加强了肠 - 脑轴与斑马鱼作为研究自闭症特征新疗法的有用工具之间的关系。以及脑组织中超氧化物歧化酶活性的增加。因此,通过斑马鱼模型可以注意到与阿莫西林的暴露相关的中心效应,与在小鼠模型中观察到的相同。此外,目前的数据加强了肠 - 脑轴与斑马鱼作为研究自闭症特征新疗法的有用工具之间的关系。
