Effect of vehicle on tumor growth in rats. Vehicles include; 12 mg UCA
, 12 mg nanoparticles
, a combination of 6 mg nanoparticles and 6 mg UCA
, or free doxorubicin
. All rats were insonated for 20 minutes after injection. Tumors treated with UCA did not show a significant increase in size over 14 days (P = .3) and had significantly less growth than rats treated with free doxorubicin after 14 days (P = .0390).
