摘要: 为研究苍耳子提取物对斑马鱼胚胎发育及运动行为的影响,取受精后12 /24 h斑马鱼胚胎,将胚胎分别置于不同浓度苍耳子提取物溶液中,在作用不同时间后,显微镜下统计孵化率、死亡率和心率;取受精后120 h斑马鱼胚胎,用不同浓度苍耳子提取物处理60 min后,利用行为学分析系统统计各组斑马鱼在0~10、10~20、20~30 min内行为轨迹,基于游行距离与游行时间得到游行速度,并统计转圈值。结果表明,苍耳子提取物对受精后12 h斑马鱼胚胎的发育有毒性,使斑马鱼胚胎的孵化率降低,在提取物浓度大于15 μg/mL时,孵化率低于40%;0.93 μg/mL苍耳子提取物可提高24 h斑马鱼胚胎的心率(P≤0.01),当提取物浓度大于7.5 μg/mL时,心率显著性降低(P≤0.01);在行为学分析中发现,当苍耳子提取物浓度大于3 μg/mL时,游行速度与转圈均值明显增加。研究认为,苍耳子提取物对斑马鱼胚胎发育有毒性作用,能够兴奋斑马鱼胚胎心率并增加其游行速度。

Abstract: We put 12/24h zebrafish embryos after fertilization into the solution of different concentrations Fructus Xanthii (FX) to investigate the toxicity of FX extract to the growth and motion behavior of zebrafish embryos. We then calculate their hatch rate, mortality rate, and heart rate under a microscope after different time. We treat 120 h zebrafish embryo for 60 minutes with different concentrations FX extract, and then record their behavior track within 0~10 m, 10~20 m, and 20~30 m with ethology analysis system. We also get swimming speed based on their swimming distance and time and their rotation value. Results show that FX extract has toxicity to 12 h zebrafish embryos after fertilization, which decrease their hatch rate. The hatch rate is below 40% when the extract concentration is greater than 15 μg/mL. FX extract of 0.93 μg/mL can increase the heart rate of 24 h zebrafish embryos (P≤0.01). We discover that swimming speed and rotation value all significantly increase when the extract concentration is greater than 3 μg/mL through ethology analysis. Our conclusion is that FX extract has toxicity to zebrafish embryos and can increase their heart rate and swimming speed.
