JuA with the concentrations 0.05g/L and 0.10g/L were tested based on the excitatory effect of 1000KIU/L penicillin and it was found that JuA could inhibit the burst induced by penicillin in CA1 pyramidal cells. Phenobarbital sodium was also applied as apositive control, and the results were in consistent with those reported.

The experimental results indicated that these metal oxide catalysts had better catalytic activities to the methylene chloride gas at low concentration, and the catalytic activities increased with the increase of temperature,but decreased with the increase of inlet gas concentration. The CrO3/potsherd catalytic activity was better than V2O5/potsherd, and the CrO3/potsherd catalyst displayed higher activity at the relative low temperature. When the reaction temperature was 320 ℃, the conversion rate could reach 99%, and the result of 100h catalyst stability experiment show that the catalytic activities have good stability.
