<title>Effect of laser treatment on stability of erythrocytes toward H&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;2&lt;/sub&gt; in patients with stroke and healthy donors</title>

Abstract

Low-energy He-Ne laser (0.5-83 Hz) of changeable frequency specifically increases the resistance of erythrocytes of patients after acute stroke to lipid peroxidation (LPO) induced by hydrogen peroxide. Increase in frequency of illumination increases the efficiency. The same treatment does not affect the LPO process in erythrocytes prepared from healthy donors. Laser beam treatment suggests to provide a reorganization of membrane structure resulting in increase of the antioxidant defense of the cell.
