title: [Ultrastructure of skeletal muscle tissue of microwave damaged chick embryos].
abstract: The effect of ultrahigh-frequency energy of electromagnetic field of low intensity on certain morphometric indices of intracellular organoids and on cellular ultrastructure were studied in the developing skeletal muscular tissue of chick embryos. In the skeletal muscles of irradiated embryos a limited cellular destruction, structural disorders in myonic organoids were revealed. Reactive-recovery processes manifested themselves in hyperplasy and hypertrophy of organoids, in activation of protein synthesis, in increasing amount of myosatellites. At early stages after irradiation peripheral mitochondria are subjected to greater changes. After hatching, central mitochondria in myons suffer more. Quantitative changes in myonic organoids and degree of their destruction seem to depend on.a peculiar differentiation of the muscular tissue, blood supply and innervation of the muscle as an organ.
