Paper Abstract

In this work we present the experimental results of a comparative study between polarized and nonpolarized laser light on the healing behavior of lesions created by the application of liquid nitrogen over the skin of Lewis rats. The aim of our work is understanding in the interactions of laser light and biological matter. In previous work we succeeded in showing that coherent light plays an important role in wound healing but the effect of polarization was not considered. We improved our experimental set up by simply adding a polarization filter and adjusting the power and exposure time to obtain an energy density of about 1.0 Joules/cm2 in order to be able to compare it with the results of our previously mentioned work. Our actual results demonstrated that polarized and nonpolarized laser light play different roles in the healing process.
