观察天麻素对脑缺血再灌注损伤星形胶质细胞胶原纤维酸性蛋白表达、乳酸脱氢酶漏出量以及一氧化氮合成酶活性的影响。结果：天麻素大、小剂量组GFAP纤维样改变减轻，强阳性反应细胞数减少；LDH漏出量下降；NOS活性减弱。

However, relatively lower column utilization limits its application to the complex proteome isolation. In case of binding biotin molecules to a specific kind of functional groups existed in protein structure, and flowing the digested peptides over the affinity column in which avidin has been immobilized, biotinylated peptides can be selectively separated and the complicated system is simplified.

因此根据需要，变换生物素试剂与蛋白质反应的作用位点，就可以选择性地分离出不同的目标肽段，从而大大提高亲和色谱柱的使用效率，降低亲和分离的成本；结合乙酰化同位素标记技术，还可以建立多种针对不同目标肽段的特色定量分析方法，ICAT即是将同位素标记与蛋白质巯基生物素化亲和分离成功结合的一个范例。

The invention provides a method for preparing a tube-shaped cathode of a direct methanol fuel cell, belonging to the fuel cell field and comprising the steps of: dispensing a single solution for gel injection molding at first, then adding a mesophase bituminous coal micro ball into the single solution and stirring evenly to obtain stable slurry, then casting the slurry into a die, preserving heat until the single solution reacts with a cross-linker completely to obtain a carbon-biscuit, after drying and sintering the biscuit in vacuum, preparing a diffusion layer and a catalyst layer on the surface by dipping process, and then coating polyester electrolyte membrane with a burette, rolling the carbon on a warm table to solidify the electrolyte membrane.

一种制备直接醇燃料电池管状阴极的方法，属于燃料电池领域。本发明首先配制凝胶注模用单体溶液，之后将中间相沥青炭微球加入到单体溶液中，搅拌均匀得到稳定的浆料，然后将浆料浇注到模具中，保温至单体与交联剂完全反应，得到炭管素坯，将素坯烘干、真空烧结后，在其表面采用浸渍工艺制备扩散层、催化剂层，然后采用滴管涂覆聚合物电解质膜，在加热台上对炭管进行滚压，使电解质膜固化。
