The results showed that during oogenesis there was no distribution of the UEA-I receptor.

结果表明，在卵子发生的各期滤泡细胞和卵母细胞中没有UEA-I受体的表达， SBA和PNA受体以不同的分布模式呈阶段性表达。

In this study, we have identified and characterized a histone H2A variant h2af1o in fish, and revealed its oocyte-specific expression pattern during oogenesis and embryogenesis.

他们在筛选到一个卵母细胞核心组蛋白H2A变体cDNA的基础上，首先分析确定了其卵母细胞特异表达的模式，接着观察到该蛋白在卵子发生过程中的磷酸化修饰作用。

And it is found that oogenesis in Drosophila and ant is similar to theoocyte apoptosis. Yolk mainly occurred in the early stage of apoptosis, which may bedue to environmental factors such and is the adaptability of the adverse environmentalmeasures.

并发现，拟黑多刺蚁与果蝇卵子发生有相似的卵母细胞凋亡现象，主要发生在卵黄形成前期，这种凋亡可能是由于环境因素的影响，对不良环境的适应性对策。

The adjustment mechanism of the follicular development is very complex. The influence of ovarian local factors and the influence from follicle itself were mainly discussed. During the oogenesis, many ultra microstructure changed.

卵泡发生的调节机制非常复杂，在此重点研究卵巢局部因子对卵母细胞发育的影响以及卵泡各结构间的相互影响，卵母细胞发育的过程中也出现了超微结构的改变。

Results (1) Lens epithelial cell apoptosis began before lens opaqueness (lens became opaque after 6 hours of incubation, while the lens epithelial cell apoptosis was detected after 3 hours of incubation);(2) Taurine could apparently inhibit H2O2-induced bovine lens epithelial cell apoptosis.

结果 晶状体上皮细胞凋亡发生于晶状体混浊之前；牛磺酸可明显抑制H2O2所致的牛晶状体上皮细胞凋亡。

Object: Cerebral vasospasm constitutes a major complication of subarachnoid hemorrhage. The pathogenesis of cerebral vasospasm is unclear, in spite of intensive investigations conducted over the past years. Even though multiple factors are proposed to be involved in cerebral vasospasm, oxyhemoglobin is one of the most important spasmogens for cerebral vasospasm that fallows aneurismal SAH.

目的：脑血管痉挛是蛛网膜下腔出血后最常见和最严重的并发症，近年来人们对SAH所致脑血管痉挛的发生机制进行了大量的研究，但迄今尚未完全阐明，众说纷纭，甚至有些观点相反，但几乎所有关于脑血管痉挛原因的报告都认为，脑血管痉挛是多种原因造成的，其中氧合血红蛋白是SAH后血管痉挛的主要启动因素之一，它对内皮细胞及平滑肌的细胞毒作用已经被报道。

With increasing of salinity , there were no obvious difference in quantity and shape of chloroplast under SEM , but their location in palisade cells occurred change .

扫描电镜下栅栏组织细胞中的叶绿体数量和形态未见明显的变化，但叶绿体在细胞中的位置发生了改变。

The thickness of palisade tissue decreased, and that of spongy tissue had no relation with salinity, the ratio of the thickness of palisade tissue to spongy tissue decreased with increasing salinity.

扫描电镜下栅栏组织细胞中的叶绿体数量和形态未见明显的变化，但叶绿体在细胞中的位置发生了改变。

With the salt concentration increasing and time prolonging, the same reflections were happened, but the shape of palisade tissues and spongy tissues cells became more deformed.

随着盐浓度的增加和胁迫时间的延长也发生了类似的变化，但是栅栏组织细胞和海面组织细胞形状变的很不规则。

The research of cytology shows that there are dramatically morphological and structure changes in the leaf: the cells of mesophyll array loosely and parenchyma cells reduced, cambium becomes thinner and degree of xylem becomes more serious, the content of chlorophyll dropped; the changes of conducting tissue and stoma structure affect transport and allocation of water and nutrient, hinder leaf growth and disturb regular metabolism of leaf, at last lead to wilt, rot and become crisp papyraceous.

细胞学研究表明，病叶组织的叶肉细胞排列疏松，薄壁细胞层次减少，形成层变薄，木质化程度加深，叶绿体减少；在病叶中由于疏导组织和气孔的结构发生变化，影响养分和水分在植株体内的运输和分配，干扰叶片的正常代谢，抑制叶片的生长发育，最终导致叶片失水萎缩、干枯，变为焦脆的干纸状。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
