Objective:To discuss the method of using High Intensity Focused Ultrasound (HIFU) System for tumor therapy to study and develop a solidification vaccine against mouse hepatic cancer H22 cell and to make elementary evaluation of the vaccine immunocompetence.Methods:A Sample machine of HIFU System for tumor therapy with its sound intensity set as 246 W/cm2 and 1054W/cm2 was adopted to deal with mouse hepatic cancer H22 cell. Results: Under the sound intensity of 1054 W/cm2 ,cells were observed to fall into pieces while the cells remained the normal shape under the sound intensity of 246W/cm2 . It was discovered that the vaccine in the former situation was strongly effective in resisting the attack from tumor cells
with P<0.05 .Conclusion: HIFU can destroy tumor cells all at once
destroy cell membrane structure under certain sound intensity and make the complete explosion and release of intracellular antigen so as to enhance the immunogenicity of vaccine.
