摘要: 目的 通过研究早期暴露于氟西汀的斑马鱼,探索氟西汀对斑马鱼五羟色胺系统及远期社交功能的影响。方法 用氟西汀早期慢性处理斑马鱼(3-6dpf),通过高效液相色谱法(HPLC)检测斑马鱼脑部的主要神经递质及部分代谢产物水平;用社交偏好实验评估斑马鱼社交行为的远期发展(30dpf)。结果 随氟西汀剂量的增加,五羟吲哚乙酸(5-HIAA)水平不断升高,而五羟色胺(5-HT)、多巴胺(DA)及3,4-二羟苯酰乙酸(DOPAC)在幼鱼(7dpf)脑内水平先增后减。在社交偏好实验结果中,对照组在毗邻鱼群的区域内总游动距离显著高于4 μM组和8 μM处理组(P均<0.01);游动时间的比较显示,对照组高于4 μM组和8 μM组(P均<0.05)。结论 斑马鱼早期暴露于氟西汀,可能通过改变5-HT水平和功能,对神经发育过程产生持续作用,继而影响到其社交能力。

Abstract: Objectives To expolore the effects toserotonin level and long-term social-related behaviour via a transient early postnatal fluoxetine exposure on zebarafish larves.Methods The level of neurotransmitters were exmained and their respective metabolites were quantified by HPLC from whole brain of larves (3~6 days post fertization)exposure to fluoxetine as well as tested the long-term social-related behaviour on zebrafish (30 days post fertization)quantified by social preference test.Results The level of 5-HIAA increased by enhancing dosage of fluoxetine,whlie the level of 5-HT,DA,DOPAC increased in low does and deceased in high dose.In social preference test,compared to the control group (1 255.50±117.95)cm,the 4 μM group (718.20±135.48)cm and 8 μM group (604.66±81.16) cm swam more distance in the area adjacent to the fish school(P<0.01);compared to the control group (1 005.61±54.86)s,the 4 μM group(754.21±85.63)s and 8 μM group(678.58±55.31)s had more time to swim in the area adjacent to the fish school(P<0.05). Conclutions The early-life exposed zebrafish shows the impaired long-term social-related behavior which may lead to sustained effect onneural development possibly via the changed level and function of the serotonin system.
