Studies on mouse nuclear transfer with compacted morula blastomeres as donors In this study, C57BL/6 mouse morulae blastomeres and Kunming white mouse MⅡoocytes were used as donors and recipients, respectively, to investigate the effects of different sucrose concentration on the manipulation time of nuclear transfer, and the in vitro development of reconstructed embryos.

The different irrigation and pruning measures have great effects on the nectarine dehiscent fruit and the main reason of dehiscent is the growth unbalance caused by great variegation of the water.

不同灌溉方式与不同修剪措施等对不同品种裂果率的影响不同，水分的剧烈变化造成生长的不均衡是导致裂果的主要原因。

These observations show that reprogramming is easier in interspecific embryos reconstructed with ES cells than that reconstructed with somatic cells, and that ES cells have the higher ability to direct the reconstructed embryo development normally than fibroblast cells. Oocytes were reconstructed with outbreeding Kunming albino mouse ES cells and enucleated rabbit oocytes, and the effects of the passages of ES cells and 6-DMAP on the development of interspecific reconstructed oocytes were analyzed. The interspecific reconstructed ES-rabbit oocytes were activated either by combined two set electric pulses and 6-DMAP or by two set electr

以上结果显示，6－DMAP能增加胚胎干细胞异种重构卵的卵裂率，对重构卵囊胚的发育率影响不大；高培养代数和低培养代数的胚胎干细胞用于异种核移植不影响异种重构卵的卵裂率和囊胚发育率；用胚胎干细胞作为供核细胞；比体细胞作为供核细胞所构建的异种重构胚更容易进行重编程，并且胚胎于细胞指导异种克隆胚胎正常发育的能力强于体细胞。

Methods 28 cases of hypospadias use pedicled prepuce Phase Ⅰ orthotropia gap to repair hypospadias.

对28例尿道下裂患儿采用带蒂包皮Ⅰ期正位开口治疗尿道下裂。

According to the relevant datums and field investigations, the paper makes No. 316 national highway in South region as research region to analyze the conditions of inoculating disasters and slope s transform destruction model and draws such conclusions:(1)Many factors such as terrain, geomorphic, lithosome and solum character, geologic structure, neotectonic movement, rainfall condition, groundwater trait, anthropokinetic and so on influence on the study region, which make the geological disasters occurred frequently and generate enormous hazards.(2)The geological disasters have such distribution characteristics: terrain and tectonic make geological disasters development of osculating correlated property, relative concentrate property, packet property, periodic property and so on.

本文首先在搜集相关资料和野外调查的基础上，以陕南316国道公路为重点研究区，全面分析了研究区域内地质灾害的孕灾条件与斜坡变形破坏模式，得到了以下认识：(1)研究路段地质灾害的发生发展主要受控于区内地形地貌、岩土体特性、地质构造与新构造运动、降雨条件、地下水特征及人类工程活动等因素：(2)研究路段发育滑坡、崩塌、泥石流和危险斜坡等四种地质灾害，具有如下的分布特征：地势与构造对地质灾害发育的密切相关性、相对集中性、群发性、周期性等；(3)研究路段斜坡地质灾害主要有六种变形破坏模式分别为：顺层滑动破坏、蠕滑—拉裂变形破坏、弯曲—拉裂—剪断破坏、旋转式滑移—拉裂破坏、楔形体滑动破坏、堆积层沿基岩面的滑动破坏模式，而且斜坡灾害的变形破坏往往是多种模式的组合。
