In the review mechanisms of protective action of a hyperthermia, light and low-intensity ultrasonic radiation are considered. These physical factors don't cause oxygen starvation, however promote the increase of organ's tolerance to an ischemia/hypoxia. On materials of original articles the analysis of preconditioning mechanisms cause by high temperatures, low-intensive ultrasonic and laser irradiation was carried out at ischemia. By comparison of processes in tissues at influence by physical factors the general triggers--active forms of oxygen (O2*, H2O2, HO*) were revealed. |
