摘要: 【摘要】 背景与目的: 探讨脱氢表雄酮(dehydroepiandrosterone,DHEA)的发育毒性。 材料与方法: 将SD孕鼠随机分为5组,每组16只,分别为阳性对照组(阿司匹林300 mg/kg),阴性对照组(蒸馏水)和DHEA10.4、20.8、41.7 mg/kg 3个剂量组,在受孕第7~16 d连续10 d给大鼠灌胃DHEA,第20 d解剖取出胎鼠,观察DHEA对母体及胎鼠的影响。 结果: DHEA剂量在10.4 mg/kg时导致孕鼠流产;20.8、41.7 mg/kg时孕鼠、胎鼠体重增加减缓,胸骨发育迟缓;41.7 mg/kg时,胎鼠内脏畸形增加。3个剂量组胎鼠活胎率均降低。 结论: DHEA对孕鼠及胎鼠均有毒性表现。

Abstract: 【ABSTRACT】 BACKGROUND & AIM: To detect maternal and fetal toxicity of dehydroepiandrosterone(DHEA). MATERIALS AND METHODS: SD pregnant female rats were divided randomly into 5 groups,16 rats in each group.The rats in positive control group received aspirin 300 mg/kg and distilled water was given to rats as the negative control group.Three DHEA groups were treated with 10.4,20.8 and 41.7 mg/kg.The rats were given DHEA from 7 d to 16 d of pregnant continuously for 10 days, and were sacrificed on 20th d of pregnancy. Adverse effects on pregnant rats and fetuses were assessed. RESULTS: DHEA at 10.4 mg/kg caused miscarriages in pregnant rats, 20.8 and 41.7 mg/kg slowed down the weight increase of mother and fetuses, and slowed sternum growth. At 41.7 mg/kg visceral abnormality in fetuses increased.All three concentrations of DHEA decreased the number of living fetuses. CONCLUSION: DHEA had adverse effects in both pregnant rats and fetuses.
