Fig. 4. Blood flow velocity of 3 d post fertilization zebrafish embryos for one cardiac cycle treated with C. dactylon, S. acuta, the positive controls and of the untreated zebrafish embryos at 3 d post fertilization.

Each value was expressed as mean±SD of three replicates, **P < 0.01 (revealed by t-test and subsequent post-hoc multiple comparisons with SNK test).
