Botanists in Yakutsk, the regional capital,discovered a book that mentioned a medicinal herb named Rumex crispus, which, it claimed, was used by the Sakha people to ease the symptoms of several illnesses, including leprosy.

首府雅库茨克的植物学家们发现了一本书，其中提到了一种名叫皱叶酸模的草药，书中称萨哈人就是用这种草药缓解包括麻风病在内的好几种疾病的症状。

Solution polymerization and amide reaction were used to synthesize the multifunctional comb-type amphiphilic polymer, stearyl methacrylate/ methylacrylic acid-ethanolamine-ethanediamine-folic acid polymer.

利用溶液聚合和成酰胺反应合成了多功能梳状两亲性共聚物，聚甲基丙烯酸-甲基丙烯酸十八酯-乙醇胺-乙二胺叶酸。

Simultaneously we prepared benzimidazolines with two methods by the reducton of benzimidazolium salts with NaBH_4 and Grignard addition with benzimidazolium salts. Thus we provided a new biomimic synthetic method for 9 kind of tetrahydro-β-carboline starting from carboxylic aicd and halid. A convenient synthetic method for preparing tetrahydro-β-carboline was provided.

本文以1，3-二甲基苯并咪唑碘盐和2-取代的1，3-二甲基苯并咪唑碘盐为原料，采用了NaBH_4还原和Grignard试剂加成两种方法，制备了9种1，3-二甲基苯并咪唑烷和2-取代的1，3-二甲基苯并咪唑烷作为四氢叶酸辅酶一碳单元转移新模型，在酸性条件下，以色胺作为接受一碳转移的亲核试剂，完成9种四氢-β-咔啉类化合物的新合成方法研究。

Increase in plasma tHcy correlates with homozygous mutation of thermolabile MTHFR and decrease in activity of MTHFR. Higher level of folate in the body can interfere the relationship between plasma tHcy and activity of MTHFR.

体内tHcy增高与MTHFR热敏感性基因纯合突变、酶活性下降有关；体内叶酸水平高低影响tHcy与MTHFR酶活性相关性。

Neubrander was able to ascertain that the benefits of –methylcobalamin in the body expresses the folate/methionine cycle, defects in transmethylation can affect vital biochemical reactions at many places in intermediary metabolism.

Neubrander能查明好处- methylcobalamin在身体表达叶酸氨基甲硫基丁酸周期，瑕疵在transmethylation在中介新陈代谢可能影响重要生物化学的反应在许多地方。不知道能不能帮助你，可是我已经尽力了！

Methods: the contents of amino acids are determined by hplc; tryp is determined by pico.tag; vita, vitd, vite, vitb1, vitb2, vitb6, vitb12, vpp, folic acid of formica rufa l. are determined by hplc. results: the amino acids of formica rufa l.

采用高压液相色谱仪测定蛋白质中17种氨基酸成分与含量，使用pico.tag柱前衍生法测定色氨酸成分与含量；使用高压液相色谱法测定维生素a、e、d、b1、b2、b6、b12、烟酸、叶酸等含量。

Results The absorption spectra of 5 - methyhetrahydrofolate remains unchanged when exposure to UVA and blue light.
