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〓.

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.

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.
