The effect of laser light exposure on survival and viabilityOf Leishmunia'major amtstigote : in ititro study

Abstract

This study was designed to evaluate the effectiveness of laser light radiation alone and laser-photosensitiser combination against Leishmania major amastigote in vitro. The result shows that laser-photosensitiser combination was more effective in killing than laser light alone. This effect may be photochemical due to absorption of laser light wavelength by exogenous photosensitiser which cause bond breaking leading to toxic effect on the amastigotes
