线粒体

They existed as dosage-effect and time-effect. All of these results proved that Sertoli cell was the first target cell, spermatogenic cell was the second one and mitochondrion was the target. Otherwise, we proved this compound can disturb the development and growth of sperms, influence the activity and amount of sperms and increase the deformation ratio.

结合组织病理和性激素及酶活性的改变，揭示该化合物睾丸毒性的靶细胞是支持细胞，其次是生精细胞，作用的靶点是细胞内的线粒体，此外还证明该化合物干扰精子的生长和发育，影响精子的活力和数目，增加畸形率，是雄性精子畸变的诱导剂。

黑纹粉蝶A.melete和樟蚕E.pyretorum的线粒体基因组22个tRNA基因的顺序均与其它鳞翅目昆虫相同，大小在60～72bp之间。

The members with Leber hereditary opˉtic neuropathy have a point mutation in mtDNA and the mutation at np11778is one of mechanisms inducing this disease.PCR technique provides a useful diagnostic aid for LHON.

该LHON家系成员存在线粒体DNA点突变，mtDNA的ND4亚单位第11778核苷酸突变是本病的发病机制之一，PCR-限制性核酸内切酶酶谱分析技术为LHON的诊断提供了依据。

Cobalt dichloride can induce apoptosis of rat hepatocellular cell line CBRH7919, and HIF-1α plays an important role in this hypoxia-induced apoptosis.

大鼠肝癌细胞随着缺氧程度的加重，细胞凋亡明显增加，伴随细胞周期进入G0/G1，阻滞及线粒体膜电位降低；HIF-1α的表达增加在此过程中发挥重要作用。

The thylakoid of chloroplast was lost, the chloroplast was shrinked and composed into several discontinuous parts, which suggest that the function of chloroplast was destroyed;(2) the cell wall was thickened clearly, plasmolysis was found in most of Platymanas subcordiformis cells;(3) the number of mitochondria increased, some cristae of mitochondria were dissolved;(4) the number of vacuolar increased and the size of vacuolar was not uniform, the shape was deformed;(5) the nucleus was deformed and part of the nucleus membrane was dissolved;(6) Golgi dicytosomes accompanied with a loose arrangement of cisternae and the peripheral tips of the dictyosome cisternae are not especially swollen.

叶绿体内的类囊体缺失，叶绿体皱缩，叶绿体被分离成几个不连续的部分，说明叶绿体功能被破坏；(2)细胞壁明显增厚，细胞壁与细胞膜存在质壁分离现象；(3)线粒体数目增多，部分内嵴遭破坏；(4)液泡数目增多，大小不等，形状不规则；(5)细胞核变形，核膜部分解体；(6)UV-B处理的高尔基体有一个排列松弛的潴泡，潴泡的外围顶端并没有特别膨大。

In the normal group, electron microscopy showed normal chondrocytes were oval, and cells and cell membrane were intact. In cytoplasm, there were abundant rough endoplasmic reticulum, dictyosome, and mitochondria with intact nucleus, and even chromatin. In the model group, chondrocytes exhibited obvious pyknosis and their shape was irregular. The areolae around cells disappeared; cell organs in cytoplasm coagulated to flaps which showed electron dense and was uneasy to observe; the shape of nucleus showed irregularity, and caryotin gathered densely.

电镜下正常对照组软骨细胞呈椭圆形，细胞及胞膜完整，包质内可见丰富的粗面内质网、高尔基体、线粒体，细胞核完整，染色质分布均匀；模型对照组软骨细胞明显固缩且外形不规则，细胞周晕消失，胞浆内细胞器凝成高电子密度的片状物不易分辨，细胞核不规则，染色质浓聚，散裂于核中。

Sequence difference between these 2 cell sublines were found in mtDNA D-loop region by sequencing.

序列测定发现，这两个肝癌细胞系在线粒体DNA的D-loop区存在序列差异。

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.
