Objective:To preparate BCUN-loaded lipid ultrasound contrast agent and detect its physical properties and contrast-enhancing effects.Methods:Mechanical oscillation was used to prepare BCUN-loaded lipid contrast agent.Density was detected and analyzed with microscope.Malvern determined intensity
disposition and Zeta potential.RP-HPLC detected envelopment rate.Cryodesiccated-microb ubbles were sterilized by 60Co irradiation.Following injected it through rabbit ear vein
effects of ultrasounic enhanced imaging in rabbit liver was observed.Results:The density of microbubble was(2.6~3.1)×109/ ml.The mean intensity was(1.05±0.20)μm.The mean Zeta potential was(12.93±1.84)mV.The mean nvelopment rate was(42.6±0.11)%.After injecting this microbubble
good and sustained ultrasounic enhanced images in rabbit liver were seen.Conclusions:BCUN-loaded lipid contrast agents were successfully prepared
which hopefullyprovide a new option oftargetingtreatment for the tumor.
