Green LED light has anti-inflammatory effects on burns in rats

• Many therapeutic options have been proposed to minimize the adverse effects on skin burns.
• Green LED light Has an anti-inflammatory effect on the skin burns of rats.
• This study suggests that Green LED light favours the healing process in burns.

PurposeThe aim of this study was to evaluate the effects of green LED light on inflammatory cells in skin burns: a histological study in rats.MethodsIn this study, 40 rats were randomly divided into 2 groups: G1 – Control (CTR) and G2 – Green Led (LED). Immediately after injury, green light (60 J/cm2, 10 s, λ520 at 550 nm) was applied in a timely manner in the four coinciding points of the wound angles and at each point, the amount of 60 J/cm 2 with a time of 10s was delivered, totaling 240 J/cm2 per session with 24 h intervals until the day before animal sacrifice at 3, 7, 14 and 21 days with a lethal dose of intraperitoneal anesthetic.ResultsIn the histological analysis, animals treated with green LED, from 7 days, showed a significant decrease (p < 0.05) in inflammatory cells when compared to control group.ConclusionsGreen LED light provides an anti-inflammatory effect on skin burns of rats.
