[Morphologic validation of the use of laser puncture in myopathies]
Abstract:
Conditions of hypokinesia from 10 to 150 days were produced in 24 4-month-old male rats. Biologically active points were irradiated by a helium-neon laser. Microscopically visualized destructive changes of muscle fibers were most pronounced on the 50-th day of hypokinesia (43.4% of muscle fibers). After laser puncture destructive changes reduced by the 50-th day to 7.2%. It was also established that after laser treatment microcirculation increased development of intramuscular connective tissue showed a delay, regenerative processes became activated. It is concluded that in the hypokinesia variant of myopathy laser puncture plays a structure-saving role and increases the restorative processes in the muscles.
Insights
Helium-neon laser therapy significantly reduced muscle fiber damage in rats with hypokinesia-induced myopathy. This laser puncture treatment also enhanced muscle regeneration and microcirculation, suggesting a protective role.
Area of Science:
- Muscle physiology
- Regenerative medicine
- Laser therapy
Background:
- Hypokinesia, or reduced physical activity, can lead to muscle atrophy and myopathy.
- Understanding the mechanisms of muscle degeneration and exploring therapeutic interventions is crucial.
Purpose of the Study:
- To investigate the effects of helium-neon laser irradiation on muscle fiber destruction in a rat model of hypokinesia.
- To evaluate the impact of laser therapy on microcirculation, connective tissue development, and regenerative processes in affected muscles.
Main Methods:
- Inducing hypokinesia in male rats for 10 to 150 days.
- Applying helium-neon laser irradiation to biologically active points.
- Microscopic analysis of muscle fiber destructive changes, microcirculation, and connective tissue.
Main Results:
- Muscle fiber destruction peaked at 43.4% on day 50 of hypokinesia.
- Laser puncture reduced destructive changes to 7.2% by day 50.
- Laser treatment increased microcirculation, delayed connective tissue development, and activated regenerative processes.
Conclusions:
- Helium-neon laser puncture demonstrates a structure-saving effect in hypokinesia-induced myopathy.
- Laser therapy promotes restorative processes and improves muscle health under conditions of reduced activity.
