Acute effects of low-level laser therapy (660 nm) on oxidative stress levels in diabetic rats with skin wounds.

Background: Laser therapy influences oxidative stress parameters such as the activity of antioxidant enzymes and the production of reactive oxygen species.

Objective: To analyze the effects of low-level laser therapy on oxidative stress in diabetics rats with skin wounds.

Methods: Thirty-six animals were divided into 4 groups: NDNI: non-diabetic rats with cutaneous wounds that not received laser therapy; NDI: non-diabetic rats with cutaneous wounds that received laser therapy; DNI: diabetic rats with skin wounds who did not undergo laser therapy; DI: rats with diabetes insipidus and cutaneous wounds and received laser therapy.
