A Helium-Neon (HeNe) continuous emission laser (632.8 nm; max. power 5 mW).
A Gallium Arsenide (GaAs) semiconductor pulse laser (904 nm; power 80 mW; pulse duration 200 ns).
Intervention: Intact skin over a section of the femur in the hind legs of rats was exposed.
Methods: Peripheral blood analysis was carried out before and after the experiments, and bone marrow was examined.
Conclusion:
The GaAs laser light induced a decrease in bone marrow mastocytes and peripheral blood basophils, with an increase in the number of eosinophils.
An increase in mitotic activity in the bone marrow was observed in the exposed groups of animals.
No significant changes were noted in Hb, Ht, erythrocyte, or reticulocyte levels in the peripheral blood, nor was there an increase in megakaryocyte emperipolesis.
