发现运动后即刻心肌线粒体脂质过氧化水平显著升高，超氧化物岐化酶活性和还原型谷胱甘肽含量显著下降。

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。

Objective: To investigate the effect of scutellaria bacalensis stem-leaf total flavonoid on lipid peroxidation induced by myocardial ischemia reperfusion in rats.

目的：探讨黄芩茎叶总黄酮预处理对缺血再灌注心肌脂质过氧化损伤的保护作用。

The lyophilization treatment of silkie fowl blood meal and the hot-air drying treatment of broiler blood meal had the strongest inhibition in lipid peroxidation. All the blood meal showed higher ability of the ferrous ion chelating.

而所有的血粉样品其螯合亚铁离子能力都达到90%以上，彼此间无显著差异，血粉样品的抑制脂质过氧化能力以乌骨鸡冷冻乾燥的血粉效果最佳(p.05)且与自肉鸡热风乾燥之血粉无显著差异。

It is suggested that mechanisms protecting epidermis of squamata species from UVB damage may involve in (1) Physical defensive mechanism: the death epidermal layer limited UVB transmitting to the viable cells;(2) Biochemical defensive mechanism: up-regulated CAT may protect skin from reactive oxygen species which may induced by UVB. Moreover, the lipid and proteins in the β-, meso- and α-layer may absorb incident UVB and formed damaged products that were limited in the original site;(3) Cellular defensive mechanism: quick initiating of proliferation of the germinal cells and forming of the new epidermis and shedding out the damaged epidermis shortened the damage process and restricted the damage area.

1物理性防御：角质层和中层阻挡绝大部分UVB透过，最大限度地减轻生发层的损伤；(2)生化性防御：通过上调CAT活性以减轻LVB诱导的活性氧对表皮的损伤，同时角质层蛋白质和中层脂类可吸收UVB，且形成的有害产物被局限于原位；(3)细胞性防御：通过迅速启动再生修复过程形成新的表皮，及时蜕去积累了脂类过氧化产物、受损蛋白质和晒斑细胞等的受损表皮，有效防止损伤的持续和蔓延。

Aβ at concentration of 10 to 100 μM caused an increase in reactive oxygen species generation and the stimulatory effect was dose dependent.

当贝他类淀粉蛋白浓度由10 μM一直提升到100 μM所产生活性氧化物的量是随著浓度呈现剂量效应，但是却无法在溶小体上产生显著的脂质过氧化效应。

AIM and METHODS:We adapted the none circulating method perfused rat heart and high performance liquid chromatography technique and compared with the control group, the ischemia reperfusion group and the Acanthopanox Senticosus group, studied the effect of Cordyceps Sinensis succi on the content of adenine nucleotides and MDA during ischemia reperfusion.

目的和方法：观察冬虫夏草对缺血再灌注过程心肌保护作用。采用Langendorff非循环式离体心脏灌流方法，与正常对照组、缺血再灌组、刺五加注射液用药组相对比，研究了冬虫夏草醇提取物对大鼠心肌缺血-再灌注过程脂质过氧化产物和腺嘌呤核苷酸含量的影响。
