Fig 2 Hatchability and heart rate between two groups.
(A-D) 48 and 72 hpf zebrafish in 90 mm dishes of the two groups. (E) The hatchability of zebrafish at each stage; Four independent experiments of 50 embryos for each group were carried out; ANOVA with Bonferroni correction. (F) Heart rate of zebrafish at each stage; n ≥ 7 for each group; two-way ANOVA with Bonferroni correction. Different letters indicate a significant difference between different time points for the same group (P < 0.05). # indicates a significant difference between the control group and the 2 μg/ml propofol group at this time point (P < 0.05). dpf, days post fertilization.
