Survival Rates of Mice Inoculated on Day 0 with ip Injections of A2780 Ovarian Carcinoma Cells^a

group	no. of animals in the group	survival rate (days)
PBS	17	40.6 ± 8.2
PBS and US	5	39.6 ± 6.5
P-105 empty micelles	13	51.9 ± 21.6
P-105 empty micelles and US	13	47.2 ± 9.0

^aThe mice were treated by ip injections of PBS or stabilized micelles on days 1, 4, 7, and 11. Some groups of animals were sonicated for 30 s with 1 MHz ultrasound at a power density of 1.2 W/cm²; ultrasound was applied to the abdominal region of a mouse 1 h after the injection.
