The objetive of present work was to study the effect of the Helium-Neon (He-Ne) and Gallium Arseniure (Ga-As) laser on ultraestructural level of the striate muscle and mitochondria through the observation by optical and electronic microscopy and inflammatory and of oxidative stress plasmatic markers: fibrinogen, nitric oxide, L-citrulline and superoxide dismutase, in rats with myopathy by intramuscular injections of adrenaline. Six groups were studied: (A) control; (B) injected with 0.05 mg/rat/day of adrenaline during 5 days; (C) injected with adrenaline and irradiated during 7 days with He-Ne (8 J.cm-2); (D) injected with adrenaline and irradiated with Ga-As (9 J.cm-2); (E) irradiated with He-Ne laser during 7 days; and (F) irradiated with Ga-As. The determination of the biomarkers was done by spectrophotometry and analyzed by Fisher test with a level of significance p
