超声主要作用包括热、机械作用和空化效应。超声波与生物组织相互作用,对生物组织的影响决定于上述三种效应。超声生物效应近来在医学研究上出现了明显的进展,现将超声空化效应在改变生物膜通透性、促进基因转染、提高化疗药物细胞毒性、损伤微血管壁、抑制细胞增殖、促进细胞 The main effects of ultrasound include heat, mechanical effects and cavitation effects. Ultrasound and biological tissue interaction, the impact on biological tissue depends on the above three effects. Ultrasound biological effects recently in medical research, there have been significant advances, now the ultrasound cavitation effect in changing the permeability of biofilm, and promote gene transfection to improve the cytotoxicity of chemotherapy drugs, damage the microvascular wall, inhibit cell proliferation and promote cell
