透膜性的

We analyse the adjustment of the birch reeds to the cold and drought from the conductance, K+ filtrate, SOD, POD, MDA, content of the water-soluble protein, penetration of the bioplasm film, photosynthesis and fluorescence.

3通过对欧洲优良无性系在寒冷、干旱的胁迫下电导率、钾离子的渗透率、酶促防御系统，膜质过氧化物，可溶性蛋白含量、原生膜透性和光合、荧光等生理指标的变化，对欧洲白桦优良无性系苗期的适应性进行分析。

2During chilling stress,Ca~(2+)treatment could delay the decrease of the activity of SOD,POD and CAT;And it could delay the decrease of the content of GSH,AsA and Car of the heat-shock-induced cucmber seedings.Therefore it enhanced the antioxydization ability,and reduced malon-diadehyde(product of membrane lipid peroxidation)and cytomembrane permeability of the heat-shock-induced cucmber seedings.

2钙处理能减缓冷胁迫下热激黄瓜幼苗的SOD、POD和CAT的活性以及GSH、AsA、Car的含量下降，因而增强了热激黄瓜幼苗的抗氧化能力，降低了膜脂过氧化产物丙二醛含量和质膜透性；而EGTA处理则相反。

Poptosis-inducing factor is a mitochondrion-localized flavoprotein with NADH oxidoreductase activity, which is encoded by the nuclear gene. Following induction of apoptosis, AIF is released from mitochondria and translocated to cytosol, and then to the nucleus. The mechanism of AIF translocation from mitochondria to nucleus is still unclear. It has been suggested that translocation is due to the presence of nuclear localization signal.

bstract： AIF(apoptosis-inducing factor)为位在粒线体内膜膜上之蛋白质，在正常细胞中，能够藉由维持电子传递链复合体I的稳定性，进而影响细胞能量的产生及自由基的清除，并且也会维持粒线体的构造；反之，当细胞遭受到不当刺激时，粒线体膜通透性改变，使得原本存在於粒腺体间质中之AIF，被释放出来，进入细胞核内造成DNA片段化，进一步促进细胞凋亡。

We also investigated the effect of mechanical force on the rate constant of 〓 permeability .

引起阳离子通透提高的影响因子是膜张力而不是膜的变形性。

Results The isolating function of nonabsorbent gauze was twice as much as that of absorbent gauze; 15sheet absorbent gauze was enough to protect burnwound and provent the oozing of humor from passing through dressing; the permeability of artificial biological dressing was 3.8 times as much as that of superficial skin graft; on wound, the stickiness of artificial biological dressing was 0.5 times as much as that of absorbent gauze.

结果 在抵抗外界污染方面，非脱脂纱布的抵抗力是脱脂纱布的2倍；在隔离保护烧伤创面方面，15层脱脂纱布已能有效保护创面从而防止渗液外漏；人造皮膜的通透性是刃厚皮片的3.8倍；人造皮膜与创面的黏附力是脱脂纱布的1/2。

The spore could germinate in 5-35℃,the optimum temperature was 25℃.The bioassay of toxin used seeding and young leaves because it could cause the evident symptom rapidly and sensitively. The toxin produced by A, tenuis Nees could change the function of the toxin on the POD, SOD and PAL was identical to A.

病原菌毒素的生测采用寄主植物切根苗、幼嫩叶片比较直观、灵敏；毒素对寄主植物膜透性有伤害作用，引起膜功能紊乱；毒素和病原菌对枸杞叶片处理后，对POD、SOD、PAL酶活性的影响有很大相似性。

As for Leucaena leucocephala seedlings, MDA is not the main product of lipid peroxidation and Tephrosia candida seedlings do not only rely on SOD and POD action to reduce active oxygen content. Through comprehensive analysis on water holding capacity of leaf, cytomembrane permeability, MDA content and SOD, POD activity, Dodonaea viscosa seedlings show the highest drought resistance, then Leucaena leucocephala, Tephrosia candida the last.

干旱胁迫对银合欢膜系统损伤生成的主要降解产物不是MDA；山毛豆清除活性氧毒害作用主要不是通过SOD和POD的作用；通过叶片相对保水力测定及膜透性、MDA相对含量、酶活性变化情况的分析，3个树种中坡柳耐旱性最强，其次为银合欢，山毛豆居后。

Plasma membrane permeability and MDA content of roots and leaves in Fagopyrum esculentum increased obviously more than that in Fagopyrum tataricum.

说明质膜透性、MDA含量和净光合速率是荞麦抗逆性敏感生理指标，苦荞的耐胁迫性大于甜荞。

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。

Besides this function, the "Jinguihuishengyi" can lead to the discharge of catecholamine, and the neurolemma polarization, and then influence the permeability of the neurolemma.

此外，金匮回生液除释放乙酰胆碱的作用外，还能引起儿茶酚胺的释放，并通过作用轴突出引起神经膜极化，从而影响神经膜的通透性。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
