Abstract

The effect of pulsed Gallium-Arsenide and continuous Helium-Neon waves on embryonic chick heart fragments in vitro were investigated.

Heart fragments were exposed for different irradiation times, varying from 1 s to 1500 s, to the laser beam. No differences could be observed between the irradiated and sham-irradiated fragments after an in vitro study of their 3 H-thymidine uptake, cell membrane permeability and cellular migration. This means that the effectiveness of low-intensity laser irradiation for wound healing can not be explained by an immediate influence on the mentioned characteristics of a living cell.
