叶酸

Objective To explore the association between the level of folate,VitB12 and acute cerebral infarction disease.Methods 88 acute ischemic cerebrovascular stroke disease events were disparted in two subgroups,32 of arteriosclerotic cerebral infarction,56 of lacunar cerebral infarction,and 35 contrast group were set up.All the participants' serum folate,VitB12 were measured when they entered the hospital.

目的 探讨急性脑梗死患者血清叶酸、VitB12水平及其临床意义方法对88例首次发病的急性缺血性脑中风患者分两亚组，动脉硬化性脑梗死组32例，腔隙性脑梗死组56例，并设对照组35例，入院后用罗氏公司Elecsys 2010型全自动电化学发光免疫分析仪测定血清叶酸、VitB12浓度。

We have shown that folic acid normalizes endothelial function in children with type 1 diabetes who have a similar degree of endothelial dysfunction but, lower total homocyst ine and higher folate status.

我们以前研究显示患1 型糖尿病伴有血管血管内皮功能障碍的儿童，虽然补充叶酸可使受损的血管内皮功能恢复正常，但是导致较低的血浆总高半胱氨酸水平和较高的血清叶酸盐水平。

Results The factors including age, exercise, the exposure time to cell phone and computer, refurnishing houses, ventilation, supplementary of folic acid, favoring frying food, reproductive knowledge, premarital consultation, parity, the opportunity of plan for conception and occupational stress were significant different between case and control groups (P.05). Logistic revealed that exercise (OR=0.319), ventilation (OR=2.496), supplementary of folic acid (OR=2.365), age (OR=1.106) and occupational stress (OR=2.159) were in the regressive model.

结果］年龄、体育锻炼、使用手机和电脑的时间、装修、通风、补充叶酸、偏爱煎炸食品、生殖知识、婚检、产次、计划受孕时间和职业紧张在病例组与对照组存在差异(P.05)，Logistic回归表明体育锻炼(OR=0.319)、通风(OR=2.496)、补充叶酸(OR=2.365)、年龄(OR=1.106)和职业紧张(OR=2.159)进入方程。

I have not had a separate meeting of folic acid, my baby is also very good, I have insisted throughout the pregnancy in pregnant women to drink milk, eat more vegetables, ready to eat when pregnant with high folic acid green leafy vegetables.

我就没单独补过叶酸，我的宝宝也挺好，我就是在整个孕期都坚持喝孕妇奶粉，多吃蔬菜，准备怀孕的时候多吃含叶酸较高的绿叶蔬菜。

Bisbenzimidazolium salts were used as a tetrahydrofolate coenzyme model, and thus the biomimetic synthesis of twenty-four acyclic diketones as precursors for macrocyclic ketones was successfully accomplished by using the addition-hydrolysis reaction of the bisbenzimidazolium salts with alkyl magnesium halide, wherein six diketones have not been reported in literature.

在本文中，受四氢叶酸辅酶的一碳单元转移反应的启发，作者以双苯并咪唑盐作为四氢叶酸辅酶模型，利用格利雅试剂与双苯并咪唑盐的加成-水解反应，成功合成了二十四种作为麝香酮及类似大环酮重要前体的长链二酮，同时，提供了一种麝香酮及类似大环酮的仿生合成新方法。

Folacin deficiency, particularly regional deficiency, is very often present in elderly patients, and correlates well with high morbidity from colon-rectal cancer.

老年人群叶酸缺乏比较普遍，局部叶酸浓度的降低增加结直肠肿瘤的发生率。

Folacin deficiency is likely one of pathogeny of breast cancer, presenting with higher cell proliferation, a lower 〓 period, higher P53 mutational protein expression and lower methyl status of P53 exons 6, 7 and 8, Folacin deficiency also increases apoptosis.

叶酸缺乏可能导致乳腺癌发病率增加，乳腺细胞株HBL-100在叶酸缺乏培养基中，生长显著增快，〓期细胞比例显著降低，凋亡率显著增加，P53突变型蛋白面积比对照组大，mRNA转录增强，P53外显子6、7和8的DNA甲基化程度降低。

Mg/kg allicin. The western medicine group was given folacin, Vit B6 and VitB 12. On the sixth weekend, the BAEP was examined and the insulin and Hcy levels were determined.

mg/kg腹腔注射；叶酸VitB6组给予叶酸、维生素B6、维生素B12灌胃；喂养6周检测脑干听觉诱发电位后处死动物，采静脉血测血糖、Hcy水平。

The protective effect of folate was not affected by time of first use or duration of use.

叶酸保护作用不受首次补充叶酸的时间或补充时间的长短影响。

A 4 weeks folate depletion period was judged to be optimal on the basis of the development of nadirs in both plasma and hepatic folate stores and elevated concentrations of plasma homocysteine.

血浆之叶酸含量及肝脏中储存的叶酸量，餵饲半纯化饲粮的鸡只，在耗竭期的第四周时，已降至谷底；而血浆高半胱胺酸之浓度则随饲养时间的增长而显著升高（P＜0.05），并且持续升高。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
