In vivo anti-tumor effects of DHA and DHA N/O/W emulsion on growth of H22tumor in ICR mice (n = 10)
Group	Dose (mg/kg)	Body weight (g) (initial/endpoint)	Tumor weight (g)	TIR (%)
NS control	-	21.9 ± 1.3/27.8 ± 2.2	1.4 ± 0.4	-
DHA solution	11.25	21.2 ± 1.2/25.3 ± 1.7	1.1 ± 0.3	21.5*
DHA N/O/W (low dose)	11.25	22.3 ± 0.9/28.6 ± 2.3	1.1 ± 0.2	23.0*
DHA N/O/W (high dose)	45.00	21.7 ± 1.1/26.3 ± 3.8	0.7 ± 0.2	51.8**

Note: ^*P < 0.05 and ^**P < 0.01 vs. N.S. control.

^#P < 0.05 vs. DHA solution or low-dose group.
