英文摘要This study examined developmental toxicity of different mercury compounds eluding some used in traditional medicines. Medaka (Oryzias latipes) embryos were exposed to 0.001-10 mu M concentrations of MeHg, HgCl2, alpha-HgS (Zhu Sha), and, beta-HgS (Zuotai) from stage 10 (6-7 hpf) to 10 days post fertilization (dpf). Of the forms of mercury in this study, the organic form (MeHg) proved the most toxic followed by inorganic mercury (HgCl2), both producing embryo developmental toxicity. Altered phenotypes included pericardial edema with elongated or tube heart, reduction of eye pigmentation, and failure of swim bladder inflation. Both alpha-HgS and, beta-HgS were less toxic than MeHg and HgCl2. Total RNA was extracted from survivors three days after exposure to MeHg (0.1 mu M), HgCl2 (1 mu M), alpha-HgS (10 mu M), or beta-HgS (10 mu M) to examine toxicity-related gene expression. MeHg and HgC12 markedly induced. metallothionein (MT) and heme oxygenase-1 (Ho-1), while alpha-HgS and beta-HgS faded to induce either gene. Chemical forms of mercury compounds proved to be a major determinant in their developmental toxicity.
