用火焰原子吸收法测定了孕28～40周正常孕妇83例,孕37～40周重度妊娠高血压综合征及41周以上妊娠妇女42例的血清铜值,并与同期尿E/C比值及新生儿Apgar评分相比较,结果提示:孕妇血清铜值在40周前随孕周的增长而增高。41周以上妊娠,重度妊高征血清铜值偏低。当尿E/C比值<10及Apgar评分≤7分时,孕妇血清铜值低,提示孕晚期母亲血清铜值可作为判断胎盘功能的辅助指标。
The levels of serum copper in 83 pregnant women with gestational age from 28 to 40 weeks, severe gestational hypertension with gestational age from 37 to 40 weeks and 42 pregnant women with gestational age above 41 weeks were determined by flame atomic absorption spectrometry. Compared with neonatal Apgar score, the results suggest that the serum copper value of pregnant women increases with gestational age 40 weeks ago. More than 41 weeks of pregnancy, severe PIH serum copper value is low. When urinary E / C ratio <10 and Apgar score ≤ 7 points, serum copper in pregnant women is low, suggesting that serum copper in the third trimester can be used as a secondary indicator of placental function.
