| 摘 要： | 本文研究了用视黄醇(维生素A)体地反应(RBPR)评价机体维生素A营养状况的可能性。共做了二个实验。实验1用110～170g重的大鼠90只,分成8组,分别给于不同水平的维生素A饲养,然后测定RBPR％和肝脏中维生素A的含量。结果表明用RBPR％能比较好地反映肝脏中维生素A的含量。实验2取体重180～320g的大鼠33只,用RBPR％计算肝脏中维生素A的含量,同时与实测的肝脏中维生素A含量比较,二个方法所得结呆一致,进一步证明了用RBPR％评价机体维生素A营养状况的可能性。初步提出了RBPR％的评价标准:>70％为缺乏,60～70％为不足,20～60％为正常,<20％为充裕。 |
A STUDY OF RETINOL BODY POOL RESPONSE (RBPR) IN EVALUATING VITAMIN A NUTRITIONAL STATUS |
|
| Abstract: | Ninety rats were divided into 8 groups. Group 1-5 were fed vitamin A free ration and each group was divided into 2 subgroups at the beginning and 12, 23, 36, 43, days after the experiment respectively. Group 6-8 were fed the ration containing 66, 132, and 198μg vitamin A per 100g diet respectively fer 30 days, and each group was also divided into 2 subgroups. The results showed that RBPR% was better than the serum vitamin A content in evaluating vitamin A nutritional status. It was suggested that the vitamin A nutritional status could be graded as follows: deficient(abore 70%)) mar-ginal(60-70%),normal (20-60%), and sufficient (under 20%)by RBPR%. |
