The weight of tumor (g) of tumor bearing groups. Data is displayed as mean ± standard error. G2: tumor control group, G3: doxorubicin-treated group, G4–G6: groups treated with 5, 10 & 20% of PSO nano-emulsion LD50, respectively. Means marked with the same superscript letters are insignificantly (p > 0.05) different, whereas those marked with different ones are significantly (p < 0.05) different.
