摘要
测定139名正常临产妇及相应的新生儿脐血清锌、红细胞锌，同时评定新生儿体格发育指标。结果表明，母亲孕晚期血清锌水平下降，达11．82±2．34μmol／L，脐血清锌为18．73±3．02μomol／L，母、脐血清锌显著正相关。而母红细胞锌增加，为212．44±26．7μol／L，脐红细胞锌则为34．92±8．67μmol／L，且与新生儿出生体重、身长、头围呈显著正相关。提示脐红细胞锌对评价新生儿锌营养状况及其与生长发育的关系有一定应用价值。
139 mothers at delivery and their 139 newborns were studied to assess the influence ofmaternal zinc status on fetal growth. The results showed that the maternal serum zinc levelswere 11. 82± 2. 34umol/L which were obviously less than those of umbilical cord of newborns (18. 73 ± 3. 02umol/L ) . However, the maternal erythrocytes zinc levels were 212. 4±26. 7umol/L which were significantly higher than those of newborns (34. 92±8. 67umol/L).There were positive correlation between maternal and fetal serum zinc, which suggested thatmaternal zinc status affected on serum zinc levels of newborns. A significant positive correlation was also found between cord erythrocyte zinc levels of newborns and the birth head-circumference, length and weight of newborns. It is suggested that the zinc concentration ofcord erythrocyte can be used as an index of fetal zinc nutritions and his growth and development.
