The CFb in blank control group was added with IMDM containing 10% FBS and those in Ang Ⅱcontrol group with Ang Ⅱ.The CFb in the 3 test groups were induced with Ang II,then added with Tau at dosages of 40,80 and 160 mmol/L respectively. Determine the proliferation of CFb by MTT method, the collagen content by oxyproline kit, the transforming growth factor- TGF-β1 (TGF TGF-β1) content by ELISA, the cell cycle by flow cytometer, the CFb NO content by nitrate reductase method, the iNOS activity by spectrophotometry, and the expression of iNOS protein by IFA.

胰酶消化法分离培养新生大鼠CFb，用Ang Ⅱ诱导促进其增殖，采用MTT法检测细胞增殖；羟脯氨酸试剂盒检测胶原含量；ELISA法测定转化生长因子β1(TGF-β1)蛋白的含量；流式细胞仪检测细胞周期；硝酸还原酶法、分光光度法和免疫荧光法检测CFb NO含量、一氧化氮合酶活性和iNOS蛋白的表达。

Synthesizing new compounds are always the goal of chemist. Recent ly, the progress of the hydrothermal synthesis method is giving a new method to synthesize new compounds. The hydrothermal synthesis method is prefectly applied to synthesizing the tunnling materials, micro-and meso-porous mat erials as well as some new materials, so this method obtained the intrest of che mist.

The main strains used in industry fermentation are Propionibacterium freudenrechii and Pseudomonas denitrificans. The basic characteristics, biosynthesis and fermentation of vitamin B12 are reviewed.

VB12主要由古生菌和一些真细菌通过有氧或厌氧两种途径合成，工业上主要采用费式丙酸菌Propionibacterium freudenrechii）和脱氮假单胞菌(Pseudomonas denitrificans进行发酵生产。

Methods The AD pathological model was made by hippocampal CA 1 lesions due to stereotaxic mini injection of quinolinic acid, the rat's learning and memory were observed by Y maze; the apoptosis of hippocampal cells were detected by using flow cytometry and electronic microscope.

用立体定位技术对海马CA1区微量注射喹啉酸造成AD模型；Y形迷宫检测大鼠学习记忆水平；电子显微镜、流式细胞仪检测海马细胞凋亡。

The conjugated structure of AOⅡ was reductively cleaved by micro-electrolysis, producing easily bio-degradable aromatic amines. The absorbance bands in the visible and ultraviolet regions were reduced or completely eliminated.

AOII分子在转鼓式内电解的作用下，其可见光和紫外光区的特征吸收峰逐渐降低直至消失，并新生成更容易生物降解的对氨基苯磺酸盐。
