[Ultrastructural consequence of shock wave exposure on VX2 cancer implanted to the urinary bladder].
In order to clarify the ultrastructural consequence of the VX2 cancer cell exposed to underwater shock waves. The VX2 cancer implanted to the urinary bladder of rabbit was received the shock waves (1000 shots, 100 MPa, 5/sec.) generated by the piezo-ceramics. Damage to the cancer cell were manifested by the three kind of findings: the one was the cell junction failure which caused the isolated cells; the second was the destruction of organelle which seemed to form the vacuole in cytoplasm; and the last finding was the emergence of moth eaten appearance in the exposed cell. We conclude that underwater shock wave exposure induces lethal injury in VX2 implanted cancer.
