Abstract
Enhanced retention of nutrients in the gravid organism, which exceeds the normal deposition in the reproductive organs and in fetuses, is called 'pregnancy anabolism'. For zinc this superretention could be established only in the liver which was enlarged in gravid rats, too. In all other tissues of gravid animals, zinc contents were lower compared with nongravid rats. After lactation, these changes in zinc status were equalized, and gravid and nongravid animals showed the same values.
摘要
妊娠机体中营养物质的保留增强，超过了生殖器官和胎儿中的正常沉积量，这被称为“妊娠合成代谢”。对于锌而言，这种超保留仅在妊娠大鼠肝脏中得以证实，该肝脏也出现了肿大。与未妊娠大鼠相比，妊娠动物的所有其他组织中的锌含量均较低。哺乳后，锌状态的这些变化趋于平衡，妊娠和未妊娠动物表现出相同的值。
