Protective effect of organic Se-containing polysaccharides against chromium-induced oxidative damage to cell DNA of mice
有机硒多糖对铬致小鼠细胞DNA 损伤与氧化损伤的保护作用

The protective effect of Se-polysaccharides extracted from Se-enriched Flammulina velutipes on the bone marrow cell DNA of mice exposed to chromium was studied by single cell gel electrophoresis. In order to evaluate the bioactivity of Se-polysaccharides,their inhibition of endogenous lipid peroxidation of mice was examined. The results showed that both tail length and tail moment of marrow cells,as compared to the control group,decreased markedly with the increase of concentration and action time in mice,w...
