RESUMO
The authors presented in the article the survey of literature data and own observations on the influence of the most practiced therapeutic physical factors (electrical, ultrasound and light) on red blood cell membrane. Low intensive laser makes an impact on protein-lipid interactions in membranes of red blood cells, has antioxidant effect and improves the function of red blood cells. It proves the use of laser irradiation in the treatment of different diseases. Heat liberation and cavitation are the most important factors of ultrasound effect on red blood cell membrane. It was established by the method of the correlation spectroscopy that direct and alternating current at its 0.22 mA/cm density decreases the diameter of monomolecular protein globules of human serum albumin. This effect is seen increased under the augmentation of exposure time and current strength. Obtain results show direct effect of the electric current on albumin as well as protein component of blood cell membrane that may be of importance in molecular mechanisms of treatment effects of this physiotherapy factor. The effect of laser irradiation, ultrasound and electrical current depend on the intensity and the duration of the effect. Clarification of the effects of molecular mechanisms on red blood cell membrane may help to develop effective physiotherapeutic technologies to use in different areas of medicine.
