线粒体

All these results suggest that PCA may have the capacity to counteract the neurotoxicity of rotenone by attenuating mitochondrial dysfunction leading to apoptosis.

这些结果表明：PCA可能是通过削弱线粒体功能失调而抑制其所致的细胞凋亡。

At last, fatty acid of leg muscle extracted and basified in the methanol. Analysed dribs and drabs of fatty acid by GC/MS, which proved L-carnitine help the transportation of long-chain fatty acid.

最后，提取小鼠腿部肌肉中的脂肪，甲酯化，用气相色谱-质谱法分析各个脂肪酸片断，验证L-肉碱帮助运输长链脂肪酸进入线粒体氧化的作用。

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.

这类物质无论在功能上还是结构上都有明显不同，它们具有以下广泛的生物学作用。1。细胞膜和细胞中亚细胞器，如叶绿体和线粒体的基本结构单元。2。定位于细胞膜上具有代谢活性蛋白质的划分单位。3。化学能和碳骨架的储藏物质。4。以生物流的形式使细胞内非极性物质得以运输。

It is on the large surface area provided by the inner cristae of mitochondria that ATP-generating

线粒体自我复制，并且可能是自由生活的原核生物在进化中形成的后代。

It is on the large surface area provided by the inner cristae of mitochondria that ATP-generating enzymes are located.

ATP 产生酶存在于线粒体上内质体的巨大表面上。

In primary spermatogonia, mitochondria were larger and spherical, and contained few cristae.

在初级精原细胞阶段，线粒体较大，多为球形，嵴少，基质电子密度低。

Mt alterations with swelling、loss of cristae、degeneration were predominant feature of heart in our study.

由此可见ADR对心肌损伤主要累及线粒体。

The mitochondria balloon swell,the mitochondrial cristae decreased or disappeared.

个别细胞线粒体呈气球样肿胀，嵴减少或消失。

According to the observed of TEM,mitochondrial of the epithelial cells were vacuolized, the cristae and membrane had disappeared. Rough endoplasmic reticulums were expansion.

透射电镜观察上皮细胞线粒体空泡化、嵴和膜消失，粗面内质网扩张，杯状细胞内含有大量的粘原颗粒。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
