Fig. 1From: Methylxanthines induce structural and functional alterations of the cardiac system in zebrafish embryosDose-response curves depicting the survival of zebrafish embryos at 72 hpf after microinjection with eight methylxanthines at 1-2 cell stage. X-axis shows the amount of drug injected in the embryos; Y axis shows the corresponding survival percentage at 72 hpf. Embryos injected with dichloroaniline (DCA) were used as positive controls. At least 100 embryos were injected for each compound and the results are the mean ± SD of three independent experimentsBack to article page
