On the morphological differentiation,by inducing of fetal calf serum,it wasshown that the cytotrophoblast cells underwent aggregation first,and the adjacentcytoplasm membranes became tightly contacted through desomosomes andcytoskeleton.Then the adjacent cytoplasm membranes disintegrated fragmentallyto form fusion pore-like structure.Finally the multinuclear cells formed and inwhich the intercellular desmosomes disappeared.Immunocytochemical stainingfurther demonstrated that the formation of syncytium was through cell membranefusion rather than the amitosis process.

细胞形态分化的研究结果表明：早孕胎盘来源的细胞滋养层细胞在血清诱导下，首先发生聚集，并通过桥粒和细胞骨架使相邻的细胞膜紧密接触；之后细胞膜发生片段断裂，形成融合孔样结构；细胞间桥粒消失，最终形成多核的合体细胞；免疫细胞化学分析进一步证实合体化是通过细胞膜融合而非无丝分裂（amitosis即细胞核分裂而细胞质不分裂）实现的。

The results showed:(1) the cellule morphous and the disposition in chick embryo of PGCs were coincident no matter stained by PAS or HE staining, and HE staining could disclose the morphologic characteristics more clearly, exactly and completely;(2) genesis of blood island could be observed at the boundary of light and dark region of the extraembryonic blastoderm at about 26 hours;(3) both the blood vessel endothelium cells and free cells of the blood island were differentiated from PGCs. The generating of genuine yolk sac was at about 44-48 hours.

结果表明：①用经典的识别原生殖细胞的PAS染色方法与HE染色所观察到的PGC在鸡胚的分布及细胞形态基本一致，而HE染色较PAS法能更有助于清晰、完整、准确地识别PGC的细胞内部结构特征；②在孵化26小时的鸡胚胚外胚盘的明暗交界处可见血岛的发生，血岛发生的时间比真正的卵黄囊产生时间（大约44-48小时）要早很多；③血岛周围的血管内皮细胞与管腔中游离细胞都来自PGC。

The results indicated that the treatment of irradiation restrained the growth and differentiation of protocorm, especially to roots.The LD50 is 67.23Gy, because the protocorm is a integrate embryoids and higher tolerance was found. Ploidy analysis showed that most of aberrant seedlings go with the change of DNA and they were not euploid. When the plants trearted by irradiation, some of aberrant seedlings appeared stem forfication, and leaves appeared chlorophyll-deficient or green-white.,probably due to some genes' expression or closing.

结果表明：辐照处理对种胚原球茎的生长和分化有抑制作用，尤其是对根的抑制更为明显；由于种胚原球茎的完整性好，耐受性强，其辐照半致死剂量(LD50)为67.23Gy；流式细胞分析表明，大多数外部形态发生改变的植株其细胞内DNA的倍性发生了改变，出现相当多的非整倍体；此外，辐照产生的变异苗出现茎分叉、叶片缺绿或白绿相间等现象，可能是由于某些基因的表达与关闭引起的。

Division of Anatomy is primarily dedicated to teaching and research in anatomy including vertebrate morphogenesis, oxygen regulation of placental development, neural coding in the hypothalamus, neurogenesis, brain mechanisms of emotion, animal models for schizophrenia, the notochord and vertebral patterning, axon guidance in the developing brain, brain information processing in cerebellar cortex.

解剖学系主要致力于解剖学的教学与研究，研究领域包括脊椎动物形态发生，胎盘发育的氧调整，丘脑下部的神经编码，神经发生，情绪情感的脑机制，神经分裂症动物模型，脊索和脊椎模型，大脑发育时轴索控制，小脑皮层中的脑信息加工等。

The identification and study of the control factors that regulate gene expression at different stages are of great value to elucidate the mechanism of spermatogenesis and spermiogenesis. Such study can also provide foundation and cues to investigating the mechanism of infertility and immunological contraception.

作为体内高度分化的雄性生殖细胞，精子发生过程中经历了从形态到生化的复杂变化，在这一过程中有一系列的特定基因按严格的时空顺序转录和翻译，因此寻找和研究不同发育阶段的差异表达的基因，将有助于最终阐明精子发生的机理，并为控制生育和不育机理的探索提供新的线索。

The floral morphogenesis of Coptis was observed under scanning electron microscopy. The initiation of all floral organs of the genus is spiral, the petal primordia are slightly retarded, the developmental sequence of the stamens is centripetal,the carpel primordia are conduplicate (i.e., horse-shoe shaped), the ovaries are half closed and the ovary stalk is formed in the developmental process.

本文运用扫锚电子显微镜观察了黄连属植物花的形态发生和发育过程，结果表明，该属植物所有的花部器官均为螺旋状发生，雄蕊为向心式发育，花瓣原基有微弱的延迟发育，心皮原基为对折型，子房为半封闭类型，子房柄是在发育过程中形成的。

It is based on the development of risk in China and foreign and the construction project"s characteristic. Then, by means of system analysis, the paper discusses the elements of a construction project. It is from construction project risk"s source, main body, effect for purpose, the reason, generant modality, and so on.

对工程项目风险因素从工程项目风险的来源、工程项目风险的直接行为主体、工程项目风险对目标的影响、按管理的过程和要素、风险发生的原因、工程项目风险发生的形态、工程项目风险性质的不同角度对工程项目风险进行分析。

In order to investigate its function in various developmental events, an antibody was prepared which could specifically recognize Xenopus PAPC.

它在爪蟾原肠运动阶段的汇聚延伸运动和体节发生阶段的体节边界形成，以及早期听泡的形态发生和细胞特化过程中都有重要的作用。

Bicoid is one of the important Drosophila genes involved in the control of embryo polarity arid larvae segmentation. The protein encoded by bicoid is a homedomain-containing transcription factor, which organizes a group of polycomb genes expressed in early development of embryo and therefore named morphogen.

Bicoid是调控果蝇胚胎极性及以后分节发生过程的重要基因，这一基因编码的蛋白是一种转录调控因子，对一组早期胚胎发育过程中的多齿基因的表达具有调控作用，并被称为形态发生剂。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.
