Abstract:
Objective:To investigate and compare the effects of water extracts of Whitmania pigra Whitman and Hirudinaria ma-nillensis Lesson on the angiogenesis of Tg (kdrl:mCherry) zebrafish. Methods:The zebrafish embryos 6-8 hours after fertilization (6-8hpf) were transferred to the culture medium containing Whitmania pigra Whitman or Hirudinaria manillensis Lesson extract at different concentrations, and the culture medium containing the drugs was replaced every 24 h. And then, at 72 hpf, the larvalmorphology and intersegmental vessels were observed under a microscope. The hatchability of 48-and 72-hpf embryos, and the number of intersegmen-tal vessels and the heart rate of 72-hpf juveniles were measured. Results:Compared with the control group, when the concentration of Whitmania pigra Whitmanis was higher than 30μg· ml-1 , and the concentration of Hirudinaria manillensis Lesson was higher than 20μg· ml-1, the number of intersegmental vessels was significantly reduced (P<0. 01). Compared with the control group, at 48 hpf, when the concentration of the drug groups was higher than 40 μg· ml-1 , the hatchability of the two groups significantly decreased ( P<0. 01);at 72 hpf, the hatchability of Whitmania pigra Whitman decreased significantly at the concentration of 100 μg·ml-1 (P<0.01), while the hatchability of Hirudinaria manillensis Lesson decreased significantly at the concentration of 80 μg· ml-1(P <0. 01). There was no obvious yolk sac edema, pericardial edema and spine curvature in the two groups. The heart rate decreased sig-nificantly (P<0. 01), while was still within the normal range. Conclusion:Both Whitmania pigra Whitman and Hirudinaria manillen-sis Lesson have notable anti-angiogenic activity, and the anti-angiogenesis activity of Hirudinaria manillensis Lesson is stronger. They both have effects on the development of zebrafish embryos, while the toxicity is not obvious.
