Evaluation of the effect of the helium-neon laser (632.8 nm) on erythrocyte sedimentation rate (ESR) and packed cell volume (PCV)

Abstract

Erythrocyte aggregation is considering an essential physiological phenomenon in blood circulation, the interaction of lasers with biomaterials like blood is a crucial topic of study. It is a fundamental property of healthy blood that is crucial to the cardiovascular system. Evaluation of the vital processes of blood microscopically and in laboratory by examining the packed cell volume and erythrocyte sedimentation rate upon exposure to laser radiation for three different times. The study included 15 healthy people. Microscopic examination, packed cell volume and erythrocyte sedimentation rate methods was used during the period of examination the red blood cells and exposure of them to laser radiation for two different periods of time, recording the results after all period of time and comparing them with the control group. In this study, the effect of radiation on packed cell volume and erythrocyte sedimentation rate was observed. In terms of viscosity speed and deposition for different periods of time, it was observed that when packed cell volume are exposed to radiation for a certain period of time (10 minutes), their values will decrease as a result of the amount of radiation generated against them, and this decrease increases when the time period increases (15 minutes) .While the erythrocyte sedimentation rate is is inversely proportional to PCV, there is an increase in the erythrocyte sedimentation rate when exposed to radiation. While the microscopic examination has shown that various deformability values have varying impacts on the degree of aggregation when the radiation duration increases over long periods, which therefore has an impact on deposition. The blood is affected when exposed to large amounts of radiation or any external conditions, which lead to the emergence of problems that may negatively affect the various functions of the blood. Therefore, knowing the type of radiation and concentration are very important to know these effects. Preferred from researchers to do more research on the effect of radiation on various blood functions
