METHODS: The BEC were preincubated with crocetin (1, 0.1 and 0.01 μmol/L) for 12 h, then exposed to AGE (100 mg/L). The RAGE mRNA expression was detected by RT-PCR analysis, the intercellular adhesion molecule-1(ICAM-1) was measured by ELISA. The extracellular superoxide ion and thiobarbituric acid reactive substances were assessed with superoxide ion kit and colorimetric assay, respectively The intracellular I2O2 was also detected using the probe 2,7-dichlorofluorescein. The mitochondrial membrane potential and mitochondrial Succinate dehydrogenase were analyzed by the retention of rhodamine 123 (Rh123) and MTT.

A novel method for determination of benzoyl peroxide with spectrophotometry was developed. Inclusion ratio of β cyclodextrin to dibenzoy peroxide and benzoic acid is obtained with spectrophotometry.The mechanism of the inclusion was studied,too. The results showed that β-CD react with dibenzoyl peroxide to form a 1:1 or 2:1 host-guest complex, with the apparent formation constants of 5.0× 10~2and 2.5× 10~4 , respectively.β-CD reacts with benzoic acid to form a 1:1 host-guest complex with the apparent formation constant of 6.9 × 10~2 after the dibenzoyl peroxide was reduced by hydroxyl ammonium chloride.

A modified analysis method based on the determination of ozone—indigo disulphonate spectrophotometer(GB/T 15437-1995) in gas phase has been developed to detect the concentration of ozone in liquid phase. An analytical condition of λmax=612~615 nm,ε=20 000 L/, pH 2 is obtained by the titration of indigo disulphonate. Compared with potassium iodide method,it shows a higher precision and accuracy,CV<3.0%. The results also prove that blank experiment will bring about 5.0%systematic error.

During using anaerobic fermentation slurry as insecticide, there had many problems that are random using, non-strictly prevention and curing time, non-suitable temperature and consistency mixture ratio ctc. In this research, fristly the different mixtures are made according to the different ratio of slurry to additive. Then the insecticidal effects of the mixture are tested in different conditions so as to find the good matches of slurry and additive in laboratory. According to the up result of the good matches extents of mixture, the field experiment is made to test the mixture's insecticidal chraricter and is further found new dosage form which has many good indexes such as good insecticidal effectiveness, little additive dosis ctc. So as to looking for the dosage form's synergism, the significant analysis is done and the characters of the dosages are tested which are ecological and environmental and the new types of dosage are determined. At last, for proving the dosage's field insecticidal potency, the wide field area experiments are done and four new style dosages are triturated which adapt ecological agriculture development. Aadditionally the effective period of the mixtures are tested when other experiments are done.
