ABSTRACT
To establish a model of ocular apoptosis in zebrafish by using dibutyl phthalate(DBP), and accordingly to evaluate the activity of anti-ocular apoptosis drugs. Methods Zebrafish embryos (30 hpf) were treated with DBP(0. 1, 10, 50, 100 jxmol L " 1) for 18 h and 42 h, and the survival rate was calculated. Then zebrafish embryos (30 or 54 hpf) were incubated with DBP(0. 1, 1 , 5 , 10, 50 |j.mol L 1) for 18 h under direct or indirect light conditions, and visualized under microscope, then the ocular apoptosis was assessed by AO staining. Furthermore, modeled zebrafish was treated with N-acetyl-L-cysteine(NAC) or ginsenoside Rgl, and the effects on ocular apoptosis were observed. Results There was no mortality in zebrafish at concentrations below 10 |j,mol L"1 after modeling with DBP for 18 h and 42 h. The survival rate of zebrafish was significantly reduced with a concentration above 50 |xmol L"1 (P < 0 . 0 1) . Furthermore, obvious ocular apoptosis was found at 30 hpf after 18 h with DBP(10 (unol L"1) (P < 0. 0 1) . The zebrafish showed spontaneous apoptosis of the ocular cells at 72 h, which was not associated with light conditions. Effect of NAC or ginsenoside Rgl was observed on decreasing ocular apoptosis in zebrafish (P < 0. 05) . Conclusions DBP can be used to rapidly and efficiently establish a model of ocular apoptosis in zebrafish, which can be used for rapid evaluation of drug activity-.
