摘要: 目的 探讨以斑马鱼为动物模型进行药物毒性作用研究的可行性。方法 用不同浓度卡马西平处理发育48 h斑马鱼胚胎,于药物处理后8 h、16 h、24 h观察各组胚胎心脏形态变化,并计数心率。药物处理24 h后终止药物作用,并于4 h、8 h、24 h连续观察各组胚胎心率的恢复情况。结果 卡马西平处理引起斑马鱼胚胎心率降低,随处理时间延长和药物浓度升高下降越明显,卡马西平引起胚胎心率下降的 24 h EC50约为626.07 µmol/L,终止药物作用后8 h,胚胎心率恢复至正常水平。结论 卡马西平引起斑马鱼胚胎心率降低,并呈现量效依赖性,卡马西平对心率的抑制具有可逆性。

Abstract: Objective To explore the feasibility of studying drug toxic and side effect with zebrafish embryos as model. Methods Fourty-eight hours post-fertilization zebrafish embryos were treated with various concentrations of carbamazepine for 24 h. Morphological changes of embryos hearts were observed and heart rate was counted at 8, 16, 24 h after treatment. Then embryos were transferred into embryo medium and the heart rate was observed at 4, 8, 24 h after treatment interruption. Results The heart rate decreased significantly after treatment with carbamazepine for 24 h and showed a good dose-effect relationship with the drug concentration. The 24 h EC50 of decrease of heart rate was about 626.07 µmol/L. Heart rate recovered quickly 8h after treatment interruption.Conclusion Carbamazepine lowered the heart rate of zebrafish embryo in a dose-dependent manner and the repression on cardiac function was reversible.
