为揭示双酚A(BPA)的发育毒性及其可能的作用机制,采用植入后全胚胎培养模型,将8.5日龄BalB/C小鼠胚胎和9.5日龄大鼠胚胎分别与含BPA的大鼠即刻离心血清共培养48h(BPA终浓度为0、40、60、80、100 mg/L),观察双酚A对小鼠和大鼠胚胎生长发育和组织器官形态分化的影响.结果显示,随着BPA剂量的增加胚胎在体外的生长发育受影响越严重,呈现出明显的剂量-效应及剂量-反应关系.≥60 mg/L的BPA可诱发小鼠及大鼠胚胎的卵黄囊生长和血管分化不良、生长迟缓及形态分化异常,严重者出现体位异常、神经系统、鳃弓发育异常及小眼、小肢芽等畸形.提示在较高剂量下,BPA对体外培养的大鼠和小鼠胚胎具有一定的毒性作用...

In order to evaluate the developmental toxicity of BPA and to investigate the possible mechanism of it in vitro, whole embryo culture was used for the study. The embryos that removed from mother mice on gestational 8.5d (GD8.5) and mother rats on gestational 9.5d (GD9.5) were cultured immediately in centrifugal serum (ICS) with a series of concentrations of 0, 40, 60, 80, 100 mg/L of BPA for 48 h to evaluate the embryo development and morphological differentiation. The results showed that the BPA inhibited the development of embryos in vitro and there was a dose-response relationship between c...
