在正常和维生素A缺乏大鼠中检查了生理剂量的全反式-[10- 3 H]维甲酸的胆汁代谢物。正常和维生素A缺乏大鼠的胆汁在24小时采集期后约占给药剂量的60%。然而,与正常大鼠相比,维生素A缺乏大鼠的放射性排泄延迟6小时。视黄酰-β-葡糖苷酸排泄对大鼠的维生素A状态特别敏感。在正常大鼠中,给药后2 h,视黄酰基-β-葡糖苷酸在胆汁中达到最大浓度235 pmol/ml,然后迅速下降。维生素A缺乏的大鼠在10小时的收集期内显示出相对恒定的代谢物浓度(100-150 pmol/ml胆汁)。正常和缺乏大鼠的视黄酸排泄量均较低。在正常大鼠中,最近发现的胆汁代谢产物视黄牛磺酸的浓度约等于视黄酰基-β-葡萄糖醛酸苷的浓度,并且比葡萄糖醛酸苷晚2 h出现在胆汁中。
Biliary metabolites from physiological doses of all-trans-[10-3H]retinoic acid were examined in normal and vitamin A-deficient rats. The bile from normal and vitamin A-deficient rats contained approximately 60% of the administered dose following a 24-h collection period. However, vitamin A-deficient rats show a 6-h delay in the excretion of radioactivity compared to normal rats. Retinoyl-β-glucuronide excretion was particularly sensitive to the vitamin A status of the rats. In normal rats, retinoyl-β-glucuronide reached a maximum concentration of 235 pmol/ml of bile 2 h following the dose and then rapidly declined. Vitamin A-deficient rats show a relatively constant concentration of this metabolite (100–150 pmol/ml of bile) over a 10-h collection period. Retinoic acid excretion was low in both normal and deficient rats. The concentration of retinotaurine, a recently identified biliary metabolite, was approximately equal to retinoyl-β-glucuronide in normal rats and appeared in the bile 2 h later than the glucuronide.
