ABSTRACT
Objective:To study the anti—tumor effect of self—made paclitaxel—carrying liposome microbubbles(PLM) radiated by fitted ultrasound on nude mice transplanted human ovarian carcinoma.
Methods:Bearing cancer nude mice were divided into 5 groups.Each was treated in a different way as PLM with ultrasound,paclitaxel injected intravenously, lipid microbubbles with ultrasound,PLM,and normal sodium control,for continual 7 days,one time a day.The tumor volumes and weights were measured and tumor inhibition rate was calculated by weight.The expression of vascular endothelial growth factor(VEGF) was detected by immunohistochemistry.
Results:Tumor volumes,weights and VEGF expression differ significantly among 5 groups(P<0.01).The inhibition rate of PLM with ultrasound group was the biggest,and the tumor volumeand VEGF level of the group were the lowest. Conclusions:PLM radiated by fitted ultrasound could effectively inhibit tumor growth in vitro,which might developto
