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。

Free radical hurts biological large molecules, lets lipid peroxid- ize and damages membrane, the weakening of antiperoxidation system in vivo (vit E, SOD, GSH-PX) will increase the harmful effect of radical on cells.

自由基损伤生物大分子，使脂类过氧化，造成膜损伤；机体抗氧化体系(维生素E，超氧化物歧化酶，谷胱甘肽过氧化物酶等)作用的削弱会加重自由基的细胞毒作用。

Objective To investigate the effects of AA-861, the specific inhibitor of 5-lipoxygenase (5-LO), on the activation, proliferation and gene expression of kupffer cell and hepatic stellate cell.

目的 探讨5-脂氧合酶（5-LO）特异性抑制剂 AA-861对肝枯否细胞和星状细胞的活化、增殖和基因表达的影响。

Additionally, we had done some work about the modification of lipases andRAMA by sugar-esters.

五个脂肪酶和RAMA经糖脂修饰后，在有机溶剂中的催化活性均有不同程度的提高。

With structure similar to that of vitamin K, Coenzyme Q10 also known as Ubiquinone 10 is a kind of fatsoluble quinone (C6H4O2), where "10" refers to the number of isoprenyl chemical subunits.

辅酶 Q10又名泛醌10，是一种脂溶性醌，其结构类似于维生素K，因其母核六位上的侧链——聚异戊烯基的聚合度为10而得名，是一种醌环类化合物。

Their findings help reveal how the enzyme prepares to assemble the bacteria's sugar-coating by plucking sugars from a fat-sugar package known as lipid II.

他们的发现帮助显示酶是如何通过从名为 lipid II 糖脂包中移出糖准备组装细菌的包糖衣。

Experimental Center of National Level One, Hubei Traditional Chinese Medica l College, Wuhan 430061）Abstract To investigate the protective effects of Jiaweisinisa n on acute liver injury induced by intraperitoneal injection of D-ga lac-tosamise, serum superoxide dismutase, malondialdehyde , glutathioe contents were measured. The pathological changes of liver wer e observed simultaneously. The results showed that JWSNS could decrease serum MD A content, but increase serum SOD and GSH activities in acute liver injury induc ed by D-GalN. It was also found that JWSNS could alleviate the degeneration and necrosis of the hypatocytes.

为研讨加味四逆散防治肝损伤的作用机理，通过动物试验，先用加味四逆散预防给药，再采用D-氨基半乳糖造成大鼠急性肝损伤模型，然后检测大鼠血清超氧化物岐化酶、丙二醛、还原型谷胱甘肽水平，同步观察该方对急性肝损伤大鼠体内脂质过氧化反应及肝脏病理改变的影响，结果表明该方可明显升高大鼠血清SOD、GSH水平，降低MDA水平，肝脏病理学检查亦表明该方使肝细胞变性坏死程度减轻。

The Arabidopsis fad2 mutant, deficient in an endoplasmic reticulum localized x-6 desaturase, had significantly decreased polyunsaturates in the extrachloroplast membrane lipids.

拟南芥fad2突变体则缺乏一个内质网定位的X-6去饱和酶，它的多不饱和脂肪酸在叶绿体外膜脂中含量显著减少。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
