Abstract：

Objective:　As　ultrasound　has　become　an　important　therapeutic　technique　on　tumor,　in　order　to　find　the　cell-killing　effect　of　focused　bi-frequency　ultrasound　activated　hematoporphyrin　derivatives,　experimental　study　was　processed　in　vitro.　Methods:　Tumor　cells　K562　and　SW-480　were　killed　by　focused　bi-frequency　ultrasound　activated　hematoporphyrin　(Hp)　derivatives　under　optimized　ultrasonic　parameters　and　the　cell-killing　effect　was　tested　by　MTT　(Thiazolyl　blue:　3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2H-　tetrazolium　bromide)　technique.　Results:　The　lower　frequency　(0.6　MHz)　was　better　than　the　higher　(1.1　MHz)　in　activating　hematoporphyrin　derivatives;　the　bi-frequency　was　better　than　monofrequency,　and　the　cell-killing　efficiency　was　2-3　times　of　sum　of　the　two　kinds　of　ultrasounds　which　constitute　bifrequency.　Incubation　for　the　16　h　was　better　than　4　h　after　the　cells　exposed　to　the　ultrasound.　Conclusion:　The　method　of　killing　tumor　cells　by　focused　bi-frequency　ultrasound　activated　hematoporphyrin　derivatives　is　presented　and　evaluated　in　this　paper.　Copyright　©　2006　ACPSEM/EA.
