In oreder to know the effect of the oocyte maturation with several heavy metal ions(Cd$^{2+}$, Hg$^{2+}$, Cu$^{2+}$, Pb$^{2+}$) on frog(Rana dybowskii) by FPH(Frog pituitary homogenate: 0.1 p.e./ml) in vitro, oocytes were cultured for 20 hours and exanimed the maturation rates with exposure of various comcentrations of those ions. The results showed that Cd$^{2+}$ at concentration of 0.1 ppm suppressed the maturation of the oocytes, while Hg$^{2+}$, Cu$^{2+}$ and Pb$^{2+}$ suppressed them significantly at 1 and 5 ppm respectively. To examine the reversibility of the inhibitory effects, the oocutes were exposed to the metal ions only for 3 hours and transferred to plain medium and cultured further for 17 hours. The oocytes were recovered from the toxic effect of the ions when they were exposed to 1 ppm of Cd$^{2+}$ for 3 hours and not available to 2.5 ppm. The effect of 2.5 ppm of Hg$^{2+}$, Cu$^{2+}$, Pb$^{2+}$ were also reversible and not available to 5 ppm for 3 hours exposure. From the abave results, it reveal that heavy metal ions in this study suppressed the maturation of oocytes at relatively low concentration. Therefore the oocyte culture system can be used as a useful tool to evaluate the toxicity of the pollutants in envirment.
