a. Animal body weight curve. The body weight was measured twice a week during the experiment. The picture represents the control animal labeled as H2O and treated-animal as SKOV3 only (SKOV3), SKOV3 + cactus pear (pear sol), and SKOV3 + 4HPR (4-HPR). b. Tumor growth curve. Tumor size in cactus pear and 4-HPR treatment groups, compared with control SKOV3 only and SKOV3 plus H2O, was significantly reduced (p < 0.05). The effect of cactus pear solution compared with 4-HPR on inhibiting tumor growth, both agents were able to inhibit SKOV3 inoculated tumor growth, the difference is not statistically significant (p > 0.05).
