摘要

The Mgsup2+/sup/Casup2+/sup and Ksup+/sup-ATPase actomyosin activity of rabbit skeletal muscle was evaluated by the Fiske-Subbarow method during a five-hour exposition of protein solutions in electromagnetic field of extremely low frequency of 8 Hz and 25 μT induction. The results of the study of the ATPase activity of actomyosin upon electromagnetic exposure have shown statistically significant changes that are characterized by a rather complex time dynamics. After 1, 2 and 4 hours of exposure of protein solutions the effect of ELF EMF exposure inhibits the ATPase activity compared to control samples, which are not exposed to the magnetic field. By the third and fifth hours of exposure to the electromagnetic field, there is a significant increase in the ATPase activity of actomyosin. It should be noted that a similar pattern of change in enzyme activity was universal, both for the environment by Mgsup2+/sup and Casup2+/sup, and in the absence of these ions in the buffer. This can evidence for Casup2+/sup-independent ways of the infuence of electromagnetic field (EMP) on biologic objects. In our opinion, the above effects are explained by EMP influence on the dynamic properties of actomyosin solutions, which are based on the processes of spontaneous dynamic formation of structure.
