[Morphology of skeletal muscles after long-term hypokinesia and laser acupuncture]

Hypokinesia (Hk) lasting for 150 days has been modelling on Wistar male rats by means of their holding in special boxes. After decapitation in 10, 20, 50, 100 and 150 days the muscles of their extremities have been studied, using stereological methods. At Hk, especially for 50 days, inhibition of morphogenesis of ultrastructures and development of certain pathological processes are noted in the muscles with their preponderance in red fibers. Laser puncture stimulates formation of the ultrastructures responsible for contraction and energy supply and sharply decreases development of the destructive processes in muscle fiber, thus providing a satisfactory endurance of hypokinesia.
