Abstract: Objective To study the toxic effect of Shujin Dingtong tablets on embryonic development of zebrafish. Methods Zebrafish embryos were treated with multiple groups of samples while the wild type was used as the negative control. Embryonic development was observed at different time points. Results The four groups of Shujin Dingtong tablets showed obvious effects on the embryonic development of zebrafish at different concentrations. At a high concentration, embryonic toxicity was mainly manifested in developmental stagnation while at a medium concentration, developmental retardation and malformation of the main organs including the heart, brain and trunk were observed. At a low concentration, most of the embryos were close to normal, and a small number of embryos showed mild developmental delay. Conclusion The main manifestations of the effect of Shujin Dingtong tablets on zebrafish are embryonic development stagnation and lag at high and medium concentrations. Additionally, the toxicity of samples from the same manufacturer has a dose-dependent positive relationship with the amount of borax contained.
