Keyword:  斑马鱼胚胎卡马西平心率半数效应浓度EC50;
Abstract: 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8h、16h、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4h、8h、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24h EC50约为626.07 mmol/L,终止药物作用后8h,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.
