%X In this study, tanshinone was extracted from Salvia miltiorrhiza. To improve the utilization and the dissolution of the drug, the tanshinone extractions were prepared at a pharmaceutical nanoscale and in the nanometer range of 100¨C200 nm. Then, the rate of tumor inhibition and the activity of antioxidant system and the thymus/spleen indices were investigated to find the antitumor effect of nanoparticles of tanshinone in cervical carcinoma-bearing mice. Our data suggest that tanshinone inhibits cervical tumor growth and the rates of tumor inhibition of all drug groups were more than 45%. The highest rate was 70.88% in the high dose of nanoscale tanshinone group. The activities of superoxide dismutase were higher in drug groups than in the model control group, and the concentrations of malondialdehyde were significantly lower. These findings suggested that tanshinone enhance the superoxide dismutase activity of the mice and decrease the malondialdehyde content. It may be one of the mechanisms of antitumor effect of tanshinone. The thymus index and spleen index were higher than normal control or model control. These data suggested that tanshinone also enhanced the immune system of mice
