使降低

However,compared to Cd~(2+) stress alone, treatment of SNP+Cd~(2+) caused more increases in SOD,CAT and POD activities, a decrease of H_2O_2 level and MDA content in leaf and root ofmung bean seedlings. These results indicated that exogenous NO induced increases inSOD, CAT and POD activities, which scavenged H_2O_2 and resultantly inhibitedmembrane lipid peroxidation in leaf and root of mung bean seedlings under Cd~(2+) stress.

说明NO通过诱导膜保护酶活性的提高，降低了活性氧水平，从而使Cd~(2+)胁迫诱导的膜脂过氧化程度降低，这可能是外源NO明显缓解Cd~(2+)胁迫抑制绿豆幼苗生长发育的原因之一。

It is well known that the large lattice mismatch (16%) and thermal expansion coefficient mismatch between GaN and sapphire substrate are the main origins of TDs. By new growing technique of LEO, we acquired high quality GaN films almost free of TDs. The stress characteristics in GaN films with MLTB growing technique is dependent on growing systems and conditions, and the changes of stress and dislocation density are rightabout; Combining buffer layers of high temperature and low temperature is first developed to growing GaN films with low dislocation density, and the mechanism of lowering TDs density is that the first buffer layer of high temperature can make nuclear in second buffer layer of low temperature bigger. This technique also can restrain yellow luminescence effectively.

众所周知，晶格失配和热应力失配是GaN异质外延中位错产生的主要原因；为此，我们对几种降低缺陷的MOCVD外延生长方法进行了新的尝试，其中尝试了侧向外延生长技术，得到了低位错密度（小于10〓/cm〓）、高质量的GaN外延层；尝试多低温缓冲层法，发现材料中的应力特性与生长系统和生长条件有关，材料中的应力与位错密度按相反方向变化；首次尝试高低温联合缓冲层法，材料中高温缓冲层可以使随后的低温缓冲层中成核颗粒增大，从而导致随后高温GaN外延膜中位错密度降低，并且能够有效地抑制黄光峰。

Data were analyzed from photographs from optical microscopy and Computer Image Analysis.Results:Gene expression level of bcl-2mRNA (numeric density and concentration of bcl-2 immunopositive neurons) in layer Ⅲ of the ipsilateral visual cortex area 17 and the laminas receiving ipsilateral geniculate input from the strabismic and deprived eyes are significantly lower than the input from the untreated eyes.

MS1和MD1组幼猫实验眼同侧视皮质17区Ⅳ层及同侧外侧膝状体Al层神经元在视觉发育敏感期内，由于长期的斜视及形觉剥夺效应以致功能低下，对Bcl-2调节的敏感性降低，以及对NTs的营养保护及上调Bcl-2 mRNA表达水平应答能力降低，在双眼竞争的神经元发育及突触连接中处于劣势，使对侧眼形成优势循环。

TNF-α can increase permeability of strial capillary endothelial cells of suinca pig cochlea.

TNF-α能使内皮细胞中的F-actin含量明显减少(P＜0.01)，且TNF-α的浓度越高F-acitn的含量降低越明显；L-Arg能进一步降低F-actin的含量(P＜0.05)；而L-NMMA则能抑制这种趋势(P＜0.05)。

In summary, pulse therapy resulted in a decreased level of activated p65 NF-κB subunits leading to decreased levels of transcriptionally active pro-inflammatory NF-κB.

总之，冲击疗法可导致激活的p65 NF-κB 亚基水平降低，从而使转录活化的促炎症反应的NF-κB 的水平降低。

The protection of AF－1 was observed with the measurement of transudatory rate of LDH ,the breaking rate of DNA and contents of LPO and SOD,Results:The intotoxincation of glutamate was decreased by AF－1 which reduced the transudatory rate of LDH,the breaking rate of DNA and the content of LPO,and increased the content of SOD in culture significantly.

通过测定乳酸脱氢酶漏出率、DNA断裂率、超氧化物歧化酶和脂质过氧化物，观察AF－1药物的保护作用。结果：高浓度的谷氨酸可增加培养神经细胞的LDH释放率和DNA断裂率，并诱导自由基产生。AF－1明显降低谷氨酸的神经细胞毒性，使LDH释放率及DNA断裂率明显降低，LPO含量明显下降，SOD含量明显升高。

Terminal oxidative inhibitors, such as KCN, Salicylhydroxamic acid , antimycin A and NaN〓, can cut off electron transport chains of cytochrome pathway and alternative pathway, marked decreased BADH protein levels. Oxidative phosphorylation uncoupler 2, 4-dinitrophenol had a similar negative effect on BADH gene expression, and exogenous ATP and ADP increased the BADH levels. These results, in conjunction with the terminal oxidation results, indicated that ATP could be a critical component in BADH gene expression.

2.2 末端氧化抑制剂KCN、SHAM、抗霉素A和NaN〓能打断呼吸链，阻断电子传递，使BADH蛋白的表达量明显降低，说明末端氧化同样参与BADH基因表达的调节：末端氧化影响基因表达的实质就是ATP的影响，线粒体磷酸化解偶联剂DNP明显降低BADH蛋白的含量，而外源的ATP和ADP对BADH基因表达的正效应作用最大。
