CORRECTION OF GAMMA RADIATION-INDUCED MALFUNCTION OF MYOCARDIUM BY LOW-INTENSIVE ELECTROMAGNETIC RADIATION
In experiments on outbred white rats the effects of consequent exposure of the heart projection area of rats to gamma-rays and to low-intensive broadband red light on electrical activity of the heart and the myocardium ultrastructure have been investigated. Low-intensive red light had positive influence on the characteristics of the ECG records. Correction of the QT and QTc internals and also amplitudes of the R and Т waves was shown. Normalization of the ECG characteristics was accompanied with alteration of the cardiac muscle ultrastructure in control group in comparison with trial one. The study showed that the exposure of a broadband red light projection area of the heart of rats exposed to γ-radiation, promoted normalization of the electrical activity of the myocardium, as well as reduced the symptoms of radiation sickness in the sub- and cellular levels.
