Metheods DLC-
Ti, pure Ti, medical stainless steel and pure copper were
implanted in the mices, and NK cell activity and Il- 2
were determined respectivgy 1, 2,4 and 6 weeks after the implantation.Results The results
imdicated that the suppression of NK cell aetivity and IL- 2 effected by the DLC- Ti was
