| Abstract: | The effects of carnosine on DNA damage induced by ascorbate Cu-phenanthroline system was studied on deoxyribose level, using TBA reaction, and made some analysis on the mechanism carnosine protect DNA. The protect effects of Mannitol?Benzoate and Dimethylsulfoxide also been studied. It was suggested that carnosine has a higher protect effect that Mannitol?Benzoate and Dimethylsulfoxide in the right systerm. |
