线粒体

Attenuatus and Sinonovacula constricta were 0.0937 (with 16S rRNA gene) and 0.1596 respectively. However, genetic distances between the two Solen species and C.

四种蛏类线粒体16S rRNA和COI基因在不同种间其明显的多态性差异，证实了16S rRNA和COI基因序列均普遍适用于蛏类种及以上阶元的系统学遗传多样性分析。

Results:Sorbaria sorbifolia extract significantly increased the activity of SOD in brain tissue, decreased the content MDA, inhibit the MAO activity. It was observed under microscope that Sorbaria sorbifolia could retrieve the degeneration of mitochondrion.

结果：珍珠梅提取物可提高D半乳糖所致大鼠脑组织SOD活性、降低MDA含量，抑制MAO活性；电子显微镜观察到珍珠梅提取物可以减轻D半乳糖导致的线粒体等超微结构的改变。

The major changes include sparse and short and loose microvilli of endodermal epithelium cells, a reduction in apical microvesicles and subapical storage vacuoles, swilling of the mitochondria and a reduction or disappear in its cristea, a decrease in rough endoplasmic reticulum, abnormation in pattern and structure of nucleus, an increased vacuolation in cells, an extend in the interval of adjacent cells.

电镜观察发现，剂量在50g/mL以上时，YS上皮细胞微绒毛稀疏变短，胞质中贮液泡减少，线粒体、内质网等内膜系统发生多种细胞病理学改变，细胞间隙增宽，连接复合体破坏。

At the age of 19 weeks, we have observed ciliated-mucous cells, some cells presented with mucous granules in the supranuclear cytoplasm and a ciliating border with short growing shafts, while the other cells presented with large mucous granules as well as compound cilia.

小粘液颗粒细胞呈柱状，胞浆顶部含有少量球形的粘液颗粒，细胞表面有短小的微绒毛，细胞核大呈椭圆形，胞浆电子密度高，胞浆下部有粗面内质网和线粒体，核上部有高尔基体。

The disintegration of tapetal cell was relayed, the inner wall of tapetal cell secreted fewer Ubish bodies.

花粉败育过程中，小孢子液泡膜和细胞质膜断裂破碎，细胞质解体，线粒体、质体、内质网等细胞器解体或退化，绒毡层持续不解体，并缺少乌氏体的分泌。

The result is consistent with previous studies. Whereas, tapetal cells of sterile anthers were disintegrated since tetrad cells were disjoined, indicating that disintegration of tapetal cells is earlier occurred in sterile anther than that in fertile anther. DNA ladder revealed that the cleavage of nuclear DNA into oligonucleosome-sized fragments to

结果表明，在花粉母细胞减数分裂后的四分体解离时期，不育花药的绒粘层细胞较可育花药提前开始裂解；在不育系S-Mo17rf3rf3花药和花粉S-(rf3)中均明显出现PCD过程的DNA片段化以及线粒体细胞色素C外渗的现象，证明了玉米CMS-S的花粉败育与花药绒粘层细胞的提前凋亡和小孢子细胞的细胞程序性死亡有关。

The sac structure projected through the pollen aperture possesses the typical nature of transfer cell, i. e complex lybrinthian wall ingrowth and abundant mitochondria, RER, dicotysomes and ribosomes under the wall. Its outer surface is closely related to the tapetal protoplast. The accumulation of storaged material in pollen start at the area near the apertures. Above restults indicate the pollen apertures may be the"door"from where nutrition flows into pollen in P. hortorum.

绒毡层物质向花粉粒的短途运输明显的表现在花粉的萌发孔区，一方面形成向外突起的囊腔，另一方面在这里具有发达的壁迷宫，而且迷宫下具丰富的线粒体，RER和高尔基体等细胞器，此外花粉内贮藏物的大量积累首先从萌发孔附近开始以及萌发孔处与绒毡层有紧密接触都说明天竺葵花粉萌发孔可能是物质进入花粉的&门户&。

本实验观察到环磷酰胺低、中剂量组的小鼠肝脏线粒体中VDAC的转录水平较对照组有所下降，而高剂量组则略高于正常对照组。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
