Abstract
In this paper, to investigate the effects of shock waves on the endothelial cells in vitro, the cells by plane shock waves are observed by microscope and the growth rate and others are measured by image processing. The peak pressure worked on the endothelial cells in water at the test case is 0.4MPa. After working shock waves on suspended cells and fixed cells, the disintegration, shape and growth are investigated. It is shown that the growth rate of suspended endothelial cells are accelerated by plane shock waves and the dividing time for cells in case of layered cells are changed by shock wave.
