In this study, the malondialdehyde content, the glutathione peroxidase activity, and the superoxide dismutase activity in black porgy Sparus macrocephalus were determined after the acute exposure to TBTCl at the concentration of 4 and 20 μg·L-1. Results showed that TBTClinhibited the SOD activity in S.macrocephalus gill slightly , but there was an obvious promotion on the SOD activity in S.macrocephalus liver.

摘 要：观察和比较了黑鲷 Sparus macrocephalus 在不同浓度的氯化三丁基锡（tri-n-butyltin chloride，TBTCl）溶液中暴露后，其鳃和肝脏组织中超氧化物歧化酶（superoxide dismutase，SOD）活性、丙二醛（malondialdehyde，MDA）含量和谷胱甘肽过氧化物酶（glutathione peroxidase，GPx）活性的变化情况。

It is found that the low dielectric constant inhibits the disproportion of pyrogallic, but it can be settled by increasing the pH or the water content of the reverse microemulsion to obtain a stable generation of the substrate. Then the activity of SOD is determined in such a system and a bell -shaped curve of the activity vs. W〓 is obtained although only subactivity is found. The reasons can be attributed to the low dielectric constant and the attraction of CTA〓.

的介电常数的降低对邻苯三酚的自氧化有抑制作用，因此实验中通过提高CTAB微乳液的表观pH或增大水化度即W〓，最终得到了一定浓度的底物超氧阴离子O〓〓·，保证了SOD活性的测定，并得到了SOD酶活性随含水量变化的&钟形&曲线。

objective:to investigate the influence of soybean isoflavones on the antioxidative effect and improving the ability of study and memory in climacteric rats.methods:forty-eight female sd climacteric rats were randomly divided into 4 groups with one control group and the other low,medium and high dose groups,which were given soybean isoflavones 0 mg/kg.bw,42 mg/kg.bw,83 mg/kg.bw and 249 mg/kg.bw by superalimentation daily for 60 days respectively.the levels of sod,gsh-px and mda in serum were measured,and the ability of study and memory in each group was deterimined by adopting the law of diving platform.results:the content of serum mda in medium and high dose groups was lower than that in control group.the activity of serum gsh-px im medium and high dose groups was significantly increased,so was the activity of serum sod in low,medium and high dose groups.conclusion:soybean isoflavones do have the obvious effect of antioxidation,and improve the ability of study and memory effectively in female sd climacteric rats.

目的：观察大豆异黄酮对更年期雌性sd大鼠抗氧化作用及学习记忆的影响。方法：选用健康更年期雌性sd大鼠，随机分成空白对照组和低、中、高剂量4组。空白对照组给予蒸馏水，实验组每日分别灌服42、83、249 mg/kg剂量的大豆异黄酮，连续60d。第60d取血测定血清过氧化脂质丙二醛含量、超氧化物歧化酶活力、谷胱甘肽过氧化物酶活力，用跳台实验方法测定大鼠学习记忆能力。结果：与空白对照组比较，中、高剂量组大鼠血清mda含量显著降低，低、中、高剂量组血清sod活力明显升高，中、高剂量组血清gsh-px活力明显升高。结论：大豆异黄酮具有明显的抗氧化作用，并有效提高更年期雌性sd大鼠的学习记忆能力。

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.

The results showed that in the growth period of R. glutinosa, soil ferulic acid, vanillic acid, and vanillin contents had a persistent increase, while β-hydroxybenzoic acid content increased first but decreased then. The addition of ferulic acid (8 μg·ml-1), vanillic acid (08 μg·ml-1), vanillin (12 μg·ml-1), and β-hydroxybenzoic acid (30 μg·ml-1) in water culture had stronger inhibitory effects on R. glutinosa root length, root mass, fresh plant mass, and plant height. Treating with test phenolic acids except β-hydroxybenzoic acid increased leaf chlorophyll content significantly, compared with the control. After treated with test phenolic acids, plant SOD and POD activities decreased after an initial increase, and plant malondialdehyde content increased. In the treatment of ferulic acid, root SOD and POD activities were the lowest, and roots were rotted and dead.
