Abstract/OtherAbstract:
Human hematopoietic cell K(562), human melenoma cell LiBr and human stomach cancer cells were exposed to ultrasound (US, 1.75 W/cm(2), 1.4, 2.16 and 2.4 MHz)in vitro in the presence or absence of hematoporphyrin (Hp, 100 microg/mL). The cell damaging effects of treatments were determined by means of the Trypan Blue dye exclusion test, MTT test and FDA test. The experimental results showed that the same cell line had different sensibilities to the US of different frequencies, and different cell line had different damage at the same acoustical radiation. The combined treatment with US and Hp enhanced greatly the cell damage, and no sensibility of insonation cells to US with Hp was observed. The cell damage tests showed that the results of MTT test corresponded well with that of Trypan Blue dye test.
