The erythrocytes through its life span undergo many oxidative stresses from various oxidants, free radicals, diabetes, lack of some antioxidant enzymes and some diseases. These oxidative stresses lose the normal rheological properties of blood cells, deformability and shorten life span of erythrocytes. Aim: The present study is to evaluate the effects of non-coherent light (solar light) and He-Ne laser on Complete Blood Count (CBC) and osmotic fragility of erythrocytes. Results: It is found that the non-coherent and coherent light decreased osmotic fragility of erythrocytes and some parameters of CBC are very influenced strongly by light irradiation. Conclusion: The irradiation of blood by non-coherent and He-Ne laser improve its rheological properties and decreases the osmotic fragility of erythrocytes (increases the resistance of erythrocytes to hypotonic solution).
