The mobile phase was a mixture of acetonirile-40 mmol·L~(-1) dipotassium hydrogen phosphate solution40∶60,containing 10 mmol·L~(-1 cetrimonium bromide, adjust pH to 7.5 by phosphoric acid and the flow rate was 1.0 mL·min~(-1),with the detection wavelength at 215 nm.

结果马来酸、叶酸和依那普利之间能够达到很好分离；马来酸依那普利的线性范围为202.5~810.0 mg.L-1，r=0.999 8(n=6)，平均回收率为99.91%，RSD=1.15%(n=9)；叶酸的线性范围为16.28~65.12 mg.L-1，r=0.999 8(n=6)，平均回收率为100.11%，RSD=1.20%(n=9)。

If improperly added easily lead to folate deficiency, 4 months after the giant could appear erythroblastic anemia, but simply as a result of insufficient intake of folic acid anemia caused by relatively rare.

如果不适当补充，容易引起叶酸缺乏，4个月后就可出现巨幼红细胞贫血，但是单纯由于叶酸摄入不足所引起的贫血比较少见。

Clinical trials are expected in the near future, although Kass says a major challenge in testing is that a high dose of folic acid for humans comparable to that given the rats would require an average-size adult to swallow more than 200 one-milligram pills per day,"an impractical and unrealistic regimen, even if the body excretes the excess."

临床实验有望在不久的将来开始，然而Kass说实验面临一个最大的问题是，如果取相当于老鼠一样大剂量的叶酸，则需要一个正常体重的成年人每天服用200片1毫克的叶酸片，&即使机体可以排泄多余的部分，这也是不实际和不现实的服药法。&

Because of its very low levels of folic acid, vitamin B12 is also small, so goat milk to feed those who should be added folic acid and vitamin B12, or can cause megaloblastic anemia.

由于其叶酸含量极低，维生素B12也少，故羊乳喂养者应添加叶酸和维生素B12，否则可引起巨幼红细胞性贫血。

Measuring the levels of folate in the blood of about 4,500 nonpregnant women ages 15 to 44 from 1999-2000 through 2003-2004, researchers found thatfolic acidlevels declined significantly in women across the three major ethnic groups in the United States.

衡量各级叶酸在血液中的约4500名孕的妇女年龄在15至44 ，从1999-2000年，通过2003年至2004年，研究人员发现，叶酸水平显着下降，妇女在全国三大族群在美国。

Objective To study relationship between serum and red blood cell folate, serum vitamin B12 (VB12), total plasma homocysteine, thermolabile genotypes, and activity of methylene-tetrahydrofolate reductase.

目的 探讨叶酸、维生素B12（VB12）、血浆总同型半胱氨酸、5，10-亚甲基四氢叶酸还原酶活性及其热敏感性基因型间的相互关系。

Methods Control group and study group were chosen from the total 36 adult female SD rats randomly copulated with the male normal rats after feeding folic acid involved and not-inolved fodder for 2 weeks.

成熟雌性SD大鼠36只随机分为实验组和对照组，分别喂以缺乏叶酸和含叶酸饲料2周后与成熟SD雄性大鼠交配，分别取孕13.5d(E13.5d)、孕17.5d(E17.5d)胚胎及新生鼠心脏。

Fancy gold-plated dangling earrings with facetted White Opal crystals.
