The analysis of DNA damage and repair was made with "comet assay".The results showed that Hela,GM1899,HepG2 and fibroblast cells were more sensitive to H 2O 2 than lymphocytes from the peripheral blood.When the dosage of H 2O 2 was 100μM,the rates of DNA damage in former types of cells were 98 ̄99%;however,that of lymphocytes only was 42.1%.With regard to DNA repair,another result showed the repair rate of Hela cells with 98% DNA damage reached 90.1% after 1 hour incubation,and there was 51.1% in lymphocytes.It is suggested that there is a more repair after DNA damage in Hela cells than lymphocytes.
