通过研究发现，艾氏腹水瘤细胞对原卟啉Ⅸ有一定的选择性吸收和瀦留作用，原卟啉Ⅸ主要定位于细胞的线粒体中；在超声结合原卟啉Ⅸ作用下，艾氏腹水瘤细胞的存活率明显下降；细胞的超微结构发生明显损伤；线粒体膜电位下降；ROS生成量显着增加；脂质过氧化水平显着增加。 actazool.org | In the ultrasound plus PPⅨ group, the survival rate of cells was significantly lower.

研究结果表明：超声激活原卟啉Ⅸ对艾氏腹水瘤细胞有着明显的协同杀伤效应，其间产生的活性氧自由基作用，降低线粒体膜电位，增加膜的脂质过氧化水平，可能是其损伤艾氏腹水瘤细胞的主要因素之一[动物学报54(5): 846– 854，2008]。 actazool.org | The decreased mitochondria membrane potential and the increased level of lipid peroxidation in the ultrasound plus PPⅨ group may be associated with reactive oxygen species.
