The Frog Embryo Teratogenesis Assay-Xenopus(FETAX) protocol was recently adopted as a valuable tool fur evaluating chemical toxicity and the effect of environmental contaminants in frogs. In this study, the teratogenecity of NiCl$_2$, Carbofuran, Diazinon were determined in the Korean frog, Rana dybowskii using the FETAX protocol. The mortality rate and the percentage of malformed larvae were investigated by probit analysis, The teratogenic concentrations(EC$_{50}$) of NiCl$_2$, Carbofuran and Diazinon were 0.4 and 1.6 and 1.9 mg/1. The embryolethal concentrations(LC$_{50}$) of NiCl$_2$, Carbofuran and Diazinon were 17.6 and 41.5 and 20.2mg/1. The teratogenic indices (TI=LC$_{50}$/EC$_{50}$) were 43.8 for NiCl$_2$, 26.0 for Carbofuran and 10.6 for Diazinon. NiCl$_2$, Carbofuran and Diazinon were shown to be potent teratogens for Rana dybowskii embryo, causing concentration related increase of edema, tail and abdomen. The study results reveal that NiCl$_2$, Carbofuran and Diazinon suppress the development of embryos at relatively low concentrations. Therefore, the Rana dybowskii embryo teratogenesis assay system was proven to be a useful tool to evaluate the toxicity of environmental pollutants.lutants. |
