The spermatogenesis in worker included spermatogonia, primary speramtocyte, second spermatocyte and spermatid, but mature sperm was not found.

工蚁精子的发生过程包括精原细胞时期和精母细胞时期，并形成了精细胞，但未形成精子。

These data suggested that the centrin isoforms played different roles in different stages of spermatogenesis. The centrin-1 gene was revealed to be relevant to the centriolar translocation to the posterior pole of cell and the elaboration of flagellum during spermiogenesis, while the centrin-2 and centrin-3 might play roles in spermatogonial mitosis but were not involved in the spermatid differentiation process.

这些结果提示，Centrin同源基因在精子发生的不同阶段发挥不同功能，其中Centrin-1与精子细胞分化期的中心体后移、鞭毛的生成及精子中轴形成可能密切相关，Centrin-2和-3则可能在精原细胞有丝分裂中起作用，而与精子细胞变态分化无关。

RESULTS: After co-culture, morphology of bone marrow stromal stem cells was changed, showing that flat cells began to retract and became spindle-shaped and some cells displayed a linear arrangement like Schwann cells.

结果：共培养后的骨髓基质干细胞形态发生改变，原来宽大扁平的胞体开始收缩，细胞胞体呈梭形，部分细胞类似施万细胞呈线性排列。

The typical structural characteristics of oil cells include, presence of a tripartite cell wall, in which the outer and inner layers are cellulose, the middle layer is a suberin layer lamellated; presence of a cupule attaching the oil vacuole to the wall; presence of plasmodesmata occurring in wall protuberances, which is coursed by the suberin layer.

成熟油细胞结构的典型特征是：具有三层暗明暗相间的细胞壁，内外两层是纤维素壁层，电子不透明，中间一层是电子透明的木栓质化壁层，由明暗相间的片层结构组成；细胞腔被油囊充满，它由一个细胞壁向内突起的杯形构造连接于细胞壁上：胞间连丝发生于由木栓质化壁层形成的一个向内的突起中。

Therefore, NAG7 gene was a nice candidate of tumor suppresser gene associated with NPC. The mechanism might be that the re-expression of NAG7 gene contributed to the change of gene expression profile and following the change of protein expression profile, then involved in the cell cycle and apoptotic regulation changed, and finally suppressed the NPC growth.

因此，NAG7基因作为鼻咽癌相关的抑瘤基因候选者，其作用机理可能是通过诱发基因表达谱的改变而引起蛋白质表达谱发生相应的改变，在一致性改变的功能分子的作用下，抑制细胞增殖，同时诱发细胞凋亡增加，从而发挥抑制鼻咽癌细胞生长的作用。

Each medicine used in the study totally has obivious effect on lens sodium-pump. Either on the molecular and cellular level or on the histological and organic level , they all have their distinctive demonstration. 1.Ouabain、Digoxine、DMSO decrease the expression of αsubunit of sodium pump on mRNA level , the cell morphology and ultramicroscopic structure demonstrated destructive effect,it indicates the cause of cataract of the medicines.2.D-thyroxine、Amphotericin B、Vitamin E increase the expression of αsubunit of sodium pump on mRNA level ,from the demonstration of the cell morphology and ultramicroscopic structure ,it indicates the medicines have protective or anti-distructive effect on lens.3.The medicines have isoform-specific action on lens sodium-pump,it indicates exploitting isoform-specific medicine has a promising clinical application.4. Lens sodium-pumps are inhibited probably lead to cataract, so in clinical medication, especially to the cardiovascular doctor, while he is using the sodium-pump inhibitors, he should pay more attention to adjust the dosage and duration of the drug therapy. 5. To creat the animal model of cataract through inhibiting lens sodium-pump, whether it can be a kind of classical method or not, it is worthy of further research.

本研究所选用的药物对晶状体钠泵均有明显的影响作用，在分子水平、细胞水平、组织器官水平均有特异的表现：1、哇巴因、地高辛、二甲基亚砜三种药物可降低晶状体钠泵α亚单位在 mRNA水平的表达，在细胞形态和超微结构上表现为损伤效应，提示了其潜在的导致白内障的可能。2、D甲状腺素、两性霉素B、维生素 E三种药物可升高晶状体钠泵α亚单位在 mRNA水平的表达，从细胞形态和超微结构上的表现，提示了其对晶状体有保护作用或抗损伤效应。3、药物作用于晶状体钠泵具有重整异构特异性，提示了开发出特异的具有重整异构作用的药物是极有临床应用前景的。4晶状体钠泵抑制后可能导致白内障的发生，故临床用药，尤其是心内科医生在使用这些钠泵抑制剂时应注意调整用药剂量及药物疗程。5 通过抑制晶状体钠泵来制作白内障动物模型能否成为一种经典的制作方法，还有待于进一步研究。

The reason Manshen NO.1 prescription can restrain accrementition in intercapillary cells and mesangial region may be due to its adjustment of NO and ET-1's contents in vivo. It is worth of doing further researchs in the future.

1、慢肾1号方对系膜增生性肾炎有良好的治疗作用，改善症状，抑制系膜细胞及基质区的增生，从而阻止肾小管硬化的发展，防止肾功能衰竭的发生，2、肾慢1号方能够提高模型组小鼠血清NO的含量，降低ET-1的含量，使之恢复正常。3、慢肾1号方可能是通过调节体内细胞因子(NO及ET-1)的含量，从而达到抑制系膜细胞及基质增生的目的，值得深入研究。

The experimental results demonstrate: the results by electronic micorscopy and opticmicroscopy all support that the water extraction of Agrimonia can inhibit the proliferation of BGC-803 and Hela in vitro, there are quite dictinct change happened after the treatment in cellphology and cell ultraconstitution.

实验结果表明，电镜和光镜结果都支持仙鹤草水提液在体外能够抑制胃癌BGC-803和宫颈癌Hela细胞株的生长，药物作用前后细胞形态和超微结构发生明显变化，出现大量坏死细胞，并能少量捕捉到凋亡细胞。

The two cells that produced by the amicronucleate cell were still without micronucleus.

在整个接合过程中，无小核细胞的大核始终没有发生可观察到的形态学变化，它最终分裂成的二个子细胞仍为无小核细胞。

In Dictyostelium amoebae, cell-type differentiation, spatial patterning, and morphogenesis are controlled by a combination of cell- autonomous mechanisms and intercellular signaling.

在变形虫盘基网柄菌中，细胞自主机制和细胞内信号的共同作用控制着细胞类型的分化、空间模式和形态发生。
