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.

Results were shown as followings:(1) Sodium selenite at 0~2.5 μmol/L significantly increased the antioxidative capacity of L-02 cells without having remarkable impact on SMMC-7721 cells;(2) Sodium selenite at concentrations above significantly increased telomerase activity, hTERT gene expression and telomere length of L-02 cells without significant impact on SMMC-7721 cells;(3) Sodium selenite at higher concentrations (larger than 5 μmol/L) resulted in peroxidation of L-02 cells, while scutellarin significantly counteracted its effect;(4) Selenium-rich amino acids from silkworm pupas in the range of 0.5~2.5 μmol/L Se significantly inhibited SMMC-7721 cell growth, induced apoptosis and cell cycle change, and the generation of reactive oxygen species. In contrast, sodium selenite and selenomethionine only had weak impact on them at the same concentrations;(5) A new selenium-containing protein was found from selenium-rich silkworm pupas, which is worthy to be study further;(6) An expression vector containing ansense RNA of hTERT gene were constructed and used to transfect SMMC-7721 cells. They were observed to inhibit hepatoma cells.
