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.
