The results are as follows:(1)in testis tissue, the expression of RB gene only was found in spermatocytes and prespermatids of seminiferous tubule of immature mice and spermatids of mature mice, and it was not found in the spermatogonia, spermatognial stem cell and primary metamorphous sperm from both immature and mature mice.

这些结果表明，RB基因在小鼠精子和卵子的发生过程中有着重要作用

Objective To study the influence of Bushenshengjing Pills on sperm motility in rats with spermatogenic cell lesion.

The changes in the weight, exponential, structure of the tissue, cell apoptosis in testis and epididymis and the changes in the sperm tectology in epididymis were measured on the day 8, 13, 21 and 35 of the treatment,respectively,by the method of morphological examination.

分别在热应激持续到8d、13d、21d和35d时，应用形态学观察法，研究受试鼠睾丸和附睾重量及指数、组织结构、细胞凋亡和附睾精子形态学的变化；应用免疫荧光细胞化学和蛋白质印迹分析的方法，研究睾丸和附睾组织中热休克蛋白70(HSP70)的表达；应用比色法检测睾丸和附睾组织内活性氧和丙二醛、抗氧化物酶(SOD、GSH-Px、CAT)的活力或浓度的变化；应用交配试验，检测雄鼠受精能力及其致孕雌鼠的产仔数的变化，用以揭示热应激对雄鼠生殖机能的影响。

The fertilization was processed by sperm in mature male gametophyte combining with egg cell on the top of archegonia on June 15 or so.

摘要樟子松发育成熟的雄配子体中的精子6月15日左右在颈卵器中上部与卵细胞结合，进行受精作用，其后，受精卵进行游离核分裂，形成8个子核时，开始形成细胞壁。

We biopsied 1-2 single blastomere from 6-8 cell cleavage stage intracytoplasmic sperm injection embryo, and using nested PCR amplified the high frequently mutation region G380R of FGFR3 gene of the single blastomere. The products of PCR were digested by restriction enzyme Bfm Ⅰ, then the digested products were detected by 10% PAGE to see whether the embryo inherted the mutation of the patient and to screen out normal embryo transfer.

活检经胞质内单精子注射(intracytoplasmic sperm injection，ICSI)授精的胚胎发育至6～8细胞期的1～2个单卵裂球，采用巢式PCR扩增单卵裂球的FGFR3基因的高发突变位点G380R区域，用限制性内切酶BfmⅠ消化巢式PCR的内扩增产物，再经10%聚丙烯酰胺凝胶电泳检测有无遗传患者的该种突变，从而筛选出正常胚胎移植。

This page provides some protocols about porcine brain tubulin, sea urchin sperm axonemes, rat liver cell cytosol and organelle fractions, organelle motility assay, tissue culture of PtK1 cells, basic protein chemistry and so on.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
