Active oxygen is found to be involved in apoptotic progress affected by exogenous SOD and measurement of SOD in cell sap. Arsenic compounds cause a decrease of SOD in cell. It is exactly the decrease that make plenty of active oxygen gather in mitochondria, and starts the apoptotic progress. The analysis of SOD values shows that active oxygen has an effect on apoptosis.

The interactions among the three active sites---N3, 04 and 05 in the most stable conformer of glycine and the three mono-value cations--~ Li~ and Na~ are investigated at the R0B3P86/6-3 1 G* level. Their relative binding strength and the binding order are compared and analyzed when the same active site reacts with three different cations or the same cation reacts with three different active sites, respectively.

In our research on study chemical reaction of active methylene compounds and brom-acetophenone. Because of brom-acetophenone is compound that contain carbonyl and halogen ,which will take place electrophilic substitution and nucleophilic addition. When active methylene compounds are ethyl acetoacetate and β-diketone, controlling reaction condition, we have found that mono-substitution's production and di-substitution's. production is isolated; active methylene compounds are acetoacetanilide and acetoacetanilide derivate, pyrrolidin-2-one derivants were obtained by substitution and close-ring reaction .but there is no report about it.

It was found that Pd-Co/active carbon catalyst was the optimal catalyst, and Pd-Co/γ-Al2O3 was also good, but silica and kieselguhr were not proper carriers for the object reaction, because of their stronger surface acidity, which could result in the formation of polymer, jammed the micro pores of catalyst, and then resulted in its deactivation. Addition of Bi, Ce and Cu promoters could not improve the activity of catalyst, but La and Ba promoter could enhance the activity of catalyst apparently, and the Co was the best promoter, especially Co was impregnate in advance. It was attributed to that the pre-impregnated Co may occupy the micro pores of active carbon, and cover some bad functional groups on the surface of catalyst, so that the active and selectivity of catalyst could be enhanced obviously.
