The result showed that twocDNA fragments which expressed at high level both in shoot and radicle representedthe gene encoding beta-D-glucosidase; one cDNA fragment expressed specifically inshoot represented the gene encoding mitochondria HSP60; most clones of MF12 andMF17 fragments respectively represented the chloroplast genes encoding prp22 andprp19 proteins which are two components of ribosomal small subunit; while thededuced amino acid sequence from each exceptional one clone was respectivelyhomologous to CDC5 proteins and vesicle-associated membrane proteins; otherthree cDNA fragments expressed preferentially in shoot had no homologue inGenBank.

结果发现2个在胚芽和胚根中表达量都很高的cDNA片段代表的是编码玉米β-D-葡糖苷酶的基因；一个在胚芽中表达而在胚根中不表达的片段代表的是编码线粒体分子伴侣HSP60的基因；片段MFl2的大部分克隆测序结果是与叶绿体基因组中编码核糖体小亚基蛋白prp22的基因同源，但其中有一个克隆测定的cDNA片段序列推测的氨基酸序列与CDC5家族成员有较高的同源性；片段MF17的大部分克隆测序结果与叶绿体基因组中编码核糖体蛋白prp19的基因同源，而有一克隆测定的cDNA片段序列推测的氨基酸序列与参与信号转导的膜结合蛋白VAP27和VAMP有较高的同源性；另有3个优先在胚芽中表达的cDNA片段未查询到同源序列。

In this paper, the ability and mechanism of antibacterial and immune defense ofChinese shrimp was studied using cytological, biochemical, molecular biological andproteomic methods. A sensitive and stable antibacterial and lysozyme assay methodswere selected. The effect of Vibrio anguillarum and laminarin (a kind of beta-1,3-glucan) on the immune ability of haemolymph of Chinese shrimp was analyzed.The changes of total haemocyte counts, antibacterial ability, lysozyme activity andlysosome membrane stability were detected.

本文采用细胞学，生物化学，分子生物学和蛋白质组学等技术，对对虾的抗菌能力和免疫防御机制进行研究，筛选了灵敏稳定的抑菌和溶菌检测方法；并对灭活鳗弧菌和海带多糖(laminarin，一种B-1， 3 葡聚糖)免疫诱导后的中国明对虾血细胞数目，血淋巴的抑菌活力，溶菌能力，溶酶体膜的稳定性进行分析；对两种重要免疫因子溶菌酶和精氨酸激酶进行克隆和表达分析。

Objective: TO explore the molecular mechanism of the components of milkvitch-red sage compound elevating placenta blood supply from the point of view of invading by nutrient cells languishment, formation of placental decidual vas net, endurance mechanism and languishment of nutrient cells.

目的：从滋养细胞侵入、胎盘蜕膜血管网络形成、妊娠免疫监视／耐受机制、滋养细胞凋亡等角度，研究探讨黄芪、丹参复方成分提高胎盘血供的分子机制；方法：分离提取黄芪，丹参有效组分（黄芪总皂甙、总黄酮；丹参提取丹参酮、丹参醌、丹参酸三部分）。

Because the cell membrane is lipoid, lipid-soluble drugs diffuse more rapidly than relatively lipid-insoluble drugs.

由于细胞膜为类脂质，脂溶性药物的扩散比相对的非脂溶性药物更快些，小分子的透膜速度也要比大分子快。

Because the cell membrane is lipoid, lipid-soluble drugs diffuse more rapidly than relatively lipid-i oluble drugs.

由于细胞膜为类脂质，脂溶性药物的扩散比相对的非脂溶性药物更快些，小分子的透膜速度也要比大分子快。

Beforebasement membrane reconstitution, some bone marrow cells migratedto the mesenchyme, where they exhibited morphological, molecular,and functional characteristics of odontoblasts.

在基底膜重新构建完整之前，一些骨髓细胞迁移至间充质中，并从形态、分子和功能等方面表现出成牙本质细胞的特征。

In addition, a thin film made between the microelectrode and the substrate was used to minimize the diffusion of the HRP in solution.

同时在工作中为了减小HRP扩散所引起的微米点的扩大，在UME与基底之间形成一厚度为10μm左右的液膜，减小了分子扩散对结果的影响。
