Histologische Untersuchungen zu mikromorphologischen Einflssen von Lasernadelstrahlung Ergebnisse einer tierexperimentellen Untersuchung / Histological Investigation of the Micromorphological Effects of the Application of a Laser Need

Im Rahmen einer tierexperimentellen Untersuchung (Sus scrofa domesticus) konnte gezeigt werden, da die neue Lasernadelstimulation (Wellenlnge: 685 nm; Energiedichte: 4,6 kJ/cm² pro Punkt; Dauer: 20 min) wohl Verschiebungen mikrozirkulatorischer Parameter der Haut im Sinne einer Durchblutungssteigerung hervorrufen kann, die verwendete Laserqualitt und -intensitt jedoch keine nachweisbaren mikromorphologischen Vernderungen in der Haut induziert.

In an experimental animal study (Sus scrofa domesticus) we investigated the effects of the new technique of laser needle stimulation (wavelength: 685 nm; energy density: 4.6 kJ/cm² per point; application duration: 20 min)...
