2.13. Survival study
Kunming mice were injected in the right flank with 1 × 107 H22
cells/mL. After tumor growth to about 4–6 mm in diameter, mice
bearing H22 tumors were grouped (n = 8.) as follows: (1) Saline
control; (2) 5-FU, 2.0 mg/kg/d; (3) Cytoxan, 3.6 mg/kg/d; (4); Segetoside
I, 5 mg/kg/d;(5) Segetoside I, 2.5 mg/kg/d; and (6) Segetoside
I, 1.25 mg/kg/d. The different samples were administered intraperitoneally
throughout the entire experimental period. The survival
time ofthe mice was observed to evaluate the life- prolonging effect
of the different samples.
