Abstract:
Objective:To investigate the therapeutic effects of ultrasound irradiation microbubble agent in the treatment of subcutaneous H22 ascites cells hepatoma of mice.Methods:H22 ascites cells hepatoma models were established by inoculating tumor cells to subcutaneous tissue of mice.Then,mice were randomly allocated into control group,only ultrasound group,ultrasound and microbubble group.The growth of tumor volume was observed and its weight was calculated.The application of pathological examination was adopted after the treatment.The necrosis area percentage(NAP) was calculated.and the apoptotic index was analyzed with terminal deoxynucleotidyl transferase mediated dUTP nick end lebeling(TUNEL) technique.Results:Compared with the control,the growth of tumor in the ultrasound and microbubble group was slow and the inhibitory effect of tumor was obvious;Necrosis area and apoptotic cells number were also increased obviously(P
