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。

ResultsThere was no expression of Caspase-3 in group A. The expression of Caspase-3 in group C was decreased compared with that in group B（P＜0.01. In groups B and C, expansion and vacuolization of mitochondria, swollen neurons and apoptotic bodies appeared, which suggested that WBH could induce neuron injury, and the neuron injury in group C was more severe than that in group B.

结果A组大鼠海马区神经元无Caspase-3表达，B、C两组大鼠海马区神经元有Caspase-3表达，B组较C组Caspase-3表达平均灰度值减小。B、C两组大鼠海马神经元超微结构发生改变、细胞器水肿，部分线粒体空化，内质网稀疏，突触前膜、后膜结构不完整，可见自噬体结构；B组大鼠的神经元超微结构损害较C组轻。

Results Stratum ganglionare nervi optici and inner nuclear layer became thinner under light microscope,and there was pyknosis and mitochondria vacuolization under electron microscope after reperfusion for 6 hours.

结果 再灌注6 h后，光镜下模型组视网膜神经节细胞层、内核层变薄，电镜下出现核固缩，线粒体空泡化。

Ultrastructural observation showed that there was a great deal of damage by Cd2+ pollution:The thylakoids of chloroplast and cristae of mitochondria became swollen or vesiculate and disintegrated finally;The nucleus were distorted and the nuclear membrance was disrupted.

但随着毒害的加重，当超出细胞的保护限度，将会导致保护酶活性降低，抗氧化物质含量下降，而丙二醛等膜脂过氧化产物大量产生，膜透性增加，使植物体受害加剧。

In this study, we found that the mechanism for LED (630nm) repigmentation in vitiliginous skin is not through direct stimulation of melanin synthesis, proliferation, nor cellular migration. On the contrary, LED puts healthy MBs to arrest and prevents death of un-healthy cells through a cyto-protective mechanism with regulation of the mitochondria pathway of apoptosis.

我们发现红光二极体照光治疗白斑的机制，并非在於直接促进黑色素增加，使细胞增生，或是使细胞移动能力增加，反而是使黑色素母细胞一些生理功能停歇，经由调节经粒腺体的凋亡机转，来预防黑色素母细胞的死亡，进而达到保护的作用。

A healthy cell relies on its mitochondria (descendants of bacteria that took up residence in the single-celled ancestors of animals and plants about 2 billion years ago) to oxidise sugar molecules and release useful energy.

一个健康的细胞依靠它的线粒体（一种约在20亿年前存活在动植物祖先的单细胞内的细菌的后裔）来氧化糖分并释放能量。

A healthy cell relies on its mitochondria[1] (descendants of bacteria that took up residence in the single-celled ancestors of animals and plants about 2 billion years ago) to oxidise sugar molecules and release useful energy.

正常细胞依靠线粒体（是由大约20亿年前寄居在单细胞动植物祖先体内的细菌演化而来）氧化糖分子从而释放有用的能量，而大多数肿瘤细胞则通过糖酵解作用来为自身供能。

Five hours after the noise exposure, the cochleae were harvested. mitochondria energetic function, succinate dehydrogenase activity, in the hair cells of cochleae was evaluated with a colorimetric assay using blue tetrazolium monosodium salt. the sdh-labeled organs of corti were double stained with propidium iodide, a dna intercalating fluorescent probe used to visualize the morphologic viability of hair cell nuclei.

采用琥珀酸脱氢酶（succinate dehydrogenase，sdh）染色法进行耳蜗基底膜细胞线粒体染色，细胞核dna荧光染料碘化丙啶（propidium iodide，pi）双重染色耳蜗基底膜，以未受噪声暴露动物为对照，显微镜下观察噪声暴露后耳蜗基底膜核固缩和核肿胀毛细胞琥珀酸脱氢酶染色的变化。

They encompass the following broad bands of biological roles:(1) basic structural units of cellular membranes and cytologically distinct subcellular bodies such as chloroplasts and mitochondria;(2) compartmentalizing units for metabolically active proteins localized in membranes;(3) a store of chemical energy and carbon skeletons; and (4) primary transport systems of nonpolar material through biological fluids.
