EFFECT OF LASER LIGHT ON LYMPHOCYTE APOPTOSIS

Abstract

Background: Apoptosis is a physiological type of cell death characterized by certain morphological nuclear and biochemical changes. This process deletes the unwanted cells by a clean mechanism that does not evoke any inflammating changes.Objective: To show the effect of laser light on the lymphocyte apoptosis.Subject & Methods: The study was conducted on lymphocyte apoptosis. The taken number of apoptotic lymphocyte was estimated before and after exposure. Results: Results showed that there was a significant increase in the percentage of lymphocyte apoptosis after exposure to 630nm laser light, which was further increased by increasing the time of exposure.Conclusion: Lymphocyte apoptosis can be induced by low dose of laser and increasing the exposure time can increase this.
