Preparation and Characterization of the Seleno-chitosan;

In this paper,the physical and chemical properties of seleno-chitosan prepared by our lab were investigated ,and compared with that of chitosan and sulfonationed chitiosan.

By determining the reduction capability,the scavenging of 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radicals,the elimination of superoxide anion free radicals and hydroxyl free radicals,the antioxidant activity in vitro of seleno-chitosan was evaluated.

Studies on Selenoastragalan and Selenodextran ——Optimization of Seleno Reaction Conditions;

Effect of selenium chitosan on the proliferation of the in vitro cultured epidermal cell

To study the cell cycle block and inducing apoptosis effect of selenium chitosan on NB4 cells,the cell cycle block effect and inducing apoptosis effect were observed by using flow cytometry.

To investigate the effect of selenium chitosan on the proliferation of promyelocytic leukemia cells cultured in vitro,the inhibiting proliferation effect was measured by SRB and clonal assay;cell phase was observed by using flow cytometry.

The effects of selenium chiston on NB4 cells was studied by MTT,AO/EB and NBT reduced methods.

The effects of selenium chiston on proliferation and apoptosis of K562 cells and K562/ADM cells were studied by MTT and CFR methods.
