Bc1-2 基因加强表达对 OA 诱发的细胞编程死亡的效应

ＯＡ能诱发人神经母细胞瘤ＳＫ细胞进行编程死亡．死亡细胞缩小变圆，细胞质凝聚，ＤＮＡ有控降解成约２００ｂｐ左右的片段，且这一过程可由蛋白质合成抑制剂亚胺环己酮（ＣＨＸ）抑制．将编码Ｂｃ１－２全长蛋白质的ｃＤＮＡ植入ｐＸＪ４１ｎｅｏ载体中，使其表达由ＨＣＭＶ病毒启动子控制．形成的顺义（ｐＢｃｌ－２－Ｓ）及反义（ｐＢｃｌ－２－ＡＳ）表达质粒经转染导入ＳＫ细胞中获得稳定转染子，Ｗｅｓｔ－ｅｒｎ印迹表明顺义转染子表达较大量的２６ｋｄＢｃ１－２蛋白，而反义转染子则不表达．增强表达的Ｂｃ１－２基因产物对ＯＡ引ＳＫ细胞编程死亡无抑制效应．     

机械扰动下风流非稳定流动的数学模型

从流体力学基础理论和矿井风流流动的基本规律出发，推导出了机械扰动下，矿井风网内风流一维非稳定流动的数学模型。为矿井风流非稳定的分析提供了数学基础。     

关于黄土湿陷起始压力、湿陷起始含水量的探讨

在不同压力下，湿陷性黄土试验实测变形与含水量关系曲线族上有一变形陡增段，陡增段的出现表明在此含水量变化区间变形对含水量变化敏感。变形分界压力和变形分界含水量概念以及相关经验公式的初步探讨，不仅为研究黄土湿陷起始压力、湿陷起始含水量问题提供了一个新思路，而且在工程实践中也具有一定的实用价值。

Synthesis of glucoside compounds of ferrocenyl phenols and their antianemic activity

Six glucoside compounds have been synthesized by means of phase-transfer catalytic method and deacetylation from the starting material ferrocene. Their structures have been confirmed by elementary analysis, IR,¹HNMR and MS. The antianemic activities of some compounds have also been tested. Results indicate that these glucoside compounds possess the antianemic activities and therefore, the further study is well worth making.

Studies on a series complexes of copper (II), zinc (II), cobalt (III) with Schiff base derived fromd-glucosamine and salicylaldehyde

Copper (II) zinc (II) cobalt (III) complexes with the Schiff base derived from salicylaldehyde andd-glucosamine were synthesized. These compounds abbreviated as SG, CuSG, ZnSG, CoSG were characterized by elemental analyses, IR, UV-Vis,¹H NMR and MS spectrum. ESR spectrum, magnetic susceptibility measured by Evans method for CuSG had also been done. It is suggested that the complexes in solution have pseudotetrahedral structure. It was found that SG would occur a photochemical reaction if a beach of 355 nm ultravisible light shone on its aqueous solution. The reaction was in further research.
