摘要 目的研究维生素E对2,3,7,8-四氯二苯并二噁英(TCDD)致大鼠死胎及胚胎发育迟缓的影响。方法 60只妊娠Wistar大鼠分成5组,在妊娠的第6~15天,连续给予TCDD和维生素E的水平依次为:空白对照组、TCDD50 ng/kg和维生素E 0 mg/kg、TCDD 50 ng/kg和维生素E 50 mg/kg、TCDD 50 ng/kg和维生素E 100 mg/kg、TCDD50 ng/kg和维生素E 200 mg/kg。于妊娠第20天处死孕鼠,解剖观察,计数着床数,活胎数、吸收胎、死胎数,称取子宫重量,胎仔重,量取胎仔的身长及尾长。结果 50 ng/kg TCDD可显著降低平均活胎数,增加吸收、死胎率,并且引起胎鼠发育迟缓,体重、身长和尾长均显著低于对照组。而维生素E可显著降低TCDD对大鼠活胎数的影响,减少吸收、死胎率,缓解胎鼠发育迟缓。结论本实验初步证明TCDD能够降低大鼠活胎数,提高死胎率,使胚胎发育迟缓,而维生素E对其具有拮抗作用。
