Methods Fifty F-344 rats were divided into four groups, GM only一级毛片AAAA视频播放、PAA+GM、PAA only and saline control. ABR thresholds at different frequencies were measured at different times and hair cell losses were numerated. Two-dimensional diffusion assays in the culture medium were performed to evaluate the effect of PAA on the antimicrobial activity.

Nevertheless, as to the antioxidant activity, HA andβ-PPA could also protect cells against oxidative stress within a relatively short duration time when compared to α-Toc. TS didn't show any effect against oxidative stress in the range of our treated doses. In the remanding experiments, all of HA,β-PPA and TS didn't show any activity in the protection of rat primary hepatocyte cells against H2O2-induced oxidative stress, and in the inhibition of telomerase.

Comparing with chicken egg-white lysozyme which is widely used in clinic, hLYZ has many advantages: it is a natural protein in human body, so it is safe and harmless when used as a drug; its bioactivity to kill bacterium is three times higher than chicken egg-white lysozyme, and its thermal stability is much higher, too; it also has many other specific important functions which are not related with its catalysis, such as anti-virus and anti-tumor and improving immunization.

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.
