Antitumor effect and survival curve. The mice were treated with Rh2(H2cit)4 or Magh-Rh2(H2cit)4 and received seven equimolar doses of Rh2(H2cit)4 (1050 μM total dose) until 23rd day after tumor inoculation. A) Antitumor effects of Rh2(H2cit)4 and Magh-Rh2(H2cit)4. B) Survival curve for tumor-bearing mice. Values represent mean values ± standard error (n=8/each group) and different letters indicate statistical difference among treatments (p<0.05).
