he biological effect of high energy shock wdves(HESW)on human gastric adenocarcinomacell line(SGC-7901)was investigated. After exposure of the cell suspension of SGC-7901HESW induced by JT-II lithotripter
the cell viability
cell growth rate
and nmubers of colonyformed in liquid clonogenic assay were lowered.All of them were closely related to shocks andvoltage of HESW The results demomstrated that HESW can damage the human tumor cells a-cutely and lower the ability of tumorcell growth obviously.The higher the voltage and shocks ofHESW were
the more intensely the tumor cells were inhabited.
