作者用放射性~(14)C-邻苯二甲酸二丁酯(DBP)对3～4周令雄性小鼠进行脏器及组织(脑、心、肺、肝、肾、脂肪、血液)内放射性分布的测定。结果表明,不论口服或静注,DBP在体内的代谢和排泄是较快的。静注5分钟后,各脏器中的放射性以肝最高,占总剂量的3.5%;肾次之,为2.7%;脑、心、肺中有少量。60分钟后,肝升至4.5%,肾 The authors used radioactive ~ (14) C-dibutyl phthalate (DBP) to test the radioactivity in organs and tissues (brain, heart, lung, liver, kidney, fat and blood) Determination of distribution. The results show that, whether oral or intravenous, DBP in vivo metabolism and excretion is faster. After 5 minutes of intravenous injection, the radioactivity in various organs was the highest in the liver, accounting for 3.5% of the total dose; the second was 2.7% in the kidney; and a small amount in the brain, heart and lung. After 60 minutes, the liver rose to 4.5% of the kidneys
