Animals (n = 10/group) were treated as reported under Materials and methods. The percentage of inhibition rate was calculated as it follows: (average tumor weight of control group – average tumor weight of test group)/average tumor weight of control group × 100%. Significance versus Ctrl group: *p < 0.01.
