每组 12 只 Charles River CD 处女雌性大鼠在怀孕前 8 天要么补充 25,000 IU/kg 维生素 A 棕榈酸酯,要么不补充,第一个实验在怀孕第 9 天给予单剂量 5 或 10 mg/kg 全反式视黄酸 (RA)。在第二个实验中,从第 6 天到第 15 天,相似的组每天接受 4 或 8 mg/kg RA,这样每次 RA 治疗均给予补充维生素 A 的大鼠或未补充维生素 A 的大鼠。维生素 A 的高全身背景使第 9 天给予 10 mg/kg 剂量 RA 的致畸性增加了 50%,但降低了第 6-15 天给予 8 mg/kg 剂量的致畸性。讨论了这种悖论的原因,并将其与人类使用大剂量维生素进行自我治疗的倾向相关。
Groups of 12 Charles River CD virgin female rats were either supplemented with 25,000 IU/kg of vitamin A palmitate or not during the first 8 days of pregnancy and in the first experiment given a single dose of either 5 or 10 mg/kg of all-trans-retinoic acid (RA) on day 9 of pregnancy. In a second experiment, similar groups were given either 4 or 8 mg/kg RA daily from day 6 through day 15 so that each treatment with RA was given to vitamin A supplemented rats or nonsupplemented rats. The high systemic background of vitamin A increased the teratogenicity of the 10 mg/kg dose of RA given on day 9 by 50%, but reduced the teratogenicity of the 8 mg/kg dose given on days 6-15. The reasons for this paradox are discussed and related to the human propensity to self-medicate with megadoses of vitamins.
