Abstract


Laser-tissue interaction provides important information about the characteristics and behavior of biological tissues and living cells. Low intensity laser radiations are widely used in clinical practice since last 3 decades. The irradiation of blood is considered as the most efficient method for the bio stimulation of biological cells or living tissues. The purpose of this study is to investigate the effect of Low Level Laser Radiation (LLLR) on viscometric behavior of human blood. Coefficient of viscosity and size of erythrocytes are measured to understand the rheology of blood. These rheological measurements in clinical studies are generally concerned with the individual components of blood (erythrocytes, leucocytes, platelets and plasma) which collectively influence blood viscosity. Therefore, it is appropriate to measure the viscosity at three different levels- tissue level (whole blood), cellular level (erythrocytes) and molecular level (plasma). To understand the viscometric behavior of whole blood a systematic study has been done. A significant change in the coefficient of viscosity and size of erythrocytes is observed with effect of laser radiation.
