During the wall thickening, the number of Golgi bodies increased apparently and cytoplasm was filled with Golgi vesicles. Polylamellate structure of the secondary wall appeard, Along with the further development of tracheary elements, the nucleous disappeared and organelles were decreased, while cortical microtubules were arranged neatly against the inner side of plasmalemma.

初生壁与质膜之间有间隔较规律的次生壁突起；中期，线粒体和高尔基体的数量明显增加，细胞质中几乎充满高尔基体及其囊泡，次生壁中微纤丝已成有序排列；晚期，细胞核消失，导管中央形成空腔，细胞器迅速减少，仅观察到少量高尔基体和线粒体，有大量周质微管沿细胞长轴分布，且在次生壁的周围有大量小泡附着，次生壁的分层结构清晰可见。

METHODS HepG2 cells were pretreated with specific inhibitors of mitochondrial respiratory chain complexes and a mitochondrial oxidative phosphorylation uncoupler, then exposed to But.

线粒体呼吸链复合物特异性抑制剂及线粒体氧化磷酸化解偶联剂预处理HepG2细胞后，染毒But。

ResultsCompared with group A and group C, significant increase in the levels of IL 8 and MDA and decrease in the activities of SOD and GSH Px were noted in group B （F=5.86-18.41,q＝3.15-7.17, P.01）; compared with group A, the activity of SOD and GSH Px was not changed markedly, the levels of IL 8 and MDA rised slightly but with no statistically significant. Mitochondria became vacuolated and deformed in group B, slightly swollen in group C.

结果 与A组、C组相比较，B组SOD、GSH Px的活性显著下降，MDA含量、IL 8浓度显著上升(F=5.86～18.41，q＝3.15～7.17，P.01)；与A组比较，C组SOD、GSH Px活性无明显变化，MDA含量及IL 8浓度轻微上升，但无统计学差异。B组肺组织线粒体破坏，呈空泡样变，C组仅见线粒体轻微肿胀。

In conclusion, plateau zokor and plateau pika adapt better to hypoxia than SD rat by increasing the SV of mitochondria, MVD and content of Mb in the cardiac muscle. However, the parameters of mitochondria in the two high-altitude animals are different possibly because of the differences of habitats and habits.

以上结果提示，高原鼢鼠和高原鼠兔通过增加心肌线粒体SV、MVD以及Mb含量提高其在低氧环境获取氧的能力；同时，由于生境和习性上的不同，两者线粒体指标又表现出差异性。

This study demonstrated that cytotoxicity of adrenoco rtical cells induced by lead acetate is probably attributed to mitochondria oxid ative stress. Mitochondria damage might be the early cellular and molecular even t in toxic effect of lead on adrenal cortex.

线粒体氧化应激介导肾上腺皮质细胞毒性可能是PbAc毒作用机制之一，线粒体损伤是铅致肾上腺皮质毒作用的早期细胞和分子事件。

The ultrastructure of normal guinea pig papillary muscle cell showing the sarcomere and light dark band were clear, mitochondria and glycogenosome were abundant, and mitochondrial cristae and membrane were clear.

正常豚鼠乳头状肌细胞在透射电镜下显示肌节排列整齐，细胞核周线粒体和糖原颗粒含量非常丰富，且线粒体嵴和膜清晰可见。

The results showed that with the extension of AVM treatment time, the relative neuron survival rate and the mitochondria fumaric reductase activity decreased, the percentage of neuronal apoptosis increased, the mitochondria swelled, the mitochondrial structure was damaged, cristae were broken and dissolved and there were vacuoli in base.

结果显示，随着染毒时间的延长，细胞的相对存活率下降；线粒体琥珀酸脱氢酶活力降低；PI-/Rh123-细胞百分数增加；线粒体肿胀，结构不清晰，嵴断裂、溶解、基质中有片状空腔现象。

The size of follicle begin primordial follicle to tertiary follicle(1.5～3mm).The number of mitochondrion increased,and the cristae increased.Gogi body change to type,cortical granule increased,and moved behind cytolemma.The proportion of small,middle and large follicles on ovary were 92.51%(92.51±5.87),4.60%(4.60±4.91) and 2.88%(2.88±2.22) respectively.

卵泡在发育过程中，卵泡细胞形成的突起与卵母细胞始终保持密切的联系：卵母细胞从原始卵泡到直径1.5～3mm的三级卵泡，细胞质中线粒体数量由少到多，线粒体内的嵴不断增加，高尔基体由不典型到变成典型，皮质颗粒由开始形成到形成较多的皮质颗粒，并逐渐地迁移到卵母细胞膜下。

During sexual differentiation, mitochondria and smooth endoplasmic reticulum in cells of testis also increase in quantity, but it is less than that in ovary, they disintegrate after sexual differentiation. The big grana always exsist in course of sexual differentiation, but small grana don\'t appear.

分化时精巢细胞的超微结构显示线粒体和内质网数量也有增加，但不如分化中卵巢细胞的数量多，分化后线粒体和内质网解体，在整个分化过程中大颗粒一直存在，无小颗粒出现。

By electron microscope we can find the Shenqi group's cancer nuclear chromatin is partly condensing and a few with screen opening changing, the membrane is invaginating , the mitochondrias are mostly swelling and the number is decreased, with the cristae'number decreased or breakon even diminished and destructured in different degree, parts of the mitochondrias are bubbling changing.

细胞膜内陷，线粒体数量减少，多数肿胀，嵴减少或断裂，甚至消失，有不同程度的变性，部分线粒体呈空泡状。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
