Résumé
<p><b>OBJECTIVE</b>To study the teratogenicity of new high-energy compounds, 3, 4 two furazan-based oxidation furazan (DNTF) and the impact on human health, occupational exposure limits were provided for the following research.</p><p><b>METHODS</b>Pregnant SD rats were randomly divided into five groups by Standard teratogenicity test, including three dose groups (5.0, 15.8, 50.0 mg/kg), the negative control (vegetable oil), and the positive control group (CP 10.0 mg/kg). Each 10 to 15 rats were in one group. Gavage was consecutive for rats during pregnancy 7 ∼ 12 d and then sacrifice after 20 d.</p><p><b>RESULTS</b>There were no significantly difference between the three dose groups and negative controls in the pregnancy rate, the weight of pregnant rats, fetal weight, fetal growth, fetal malformation rate and internal organs,</p><p><b>CONCLUSION</b>There were no maternal toxicity, embryo toxicity and teratogenicity for rats when DNTF in the range 5.0 ∼ 50.0 mg/kg.</p>
