The Performance of the Cold Laser Therapy (GaAlAs-980nm)

Abstract

Cold laser therapy has been largely utilized to enhance wound healing caused by several bio stimulatory characteristics conferred via laser rays obviously capable towards stimulate the restoration of flexible tissues wounds. Notwithstanding, the performance of pro-inflammatory interleukins has not been investigated yet. Interleukin-1 beta (IL-1β) represents an individual of largely imperative proinflammatory cytokines, which could be concerned in wounds therapeutic. The target of this work was to investigate the influence of a 980nm laser on the IL-1β expression and its secretion in wound healing in laboratory mice. Wounds with a standard-sized of 2cm have been carried out on the face of forty-laboratory mice. Animals have been divided into two groups; half of them undergo cold laser treatment at 980 nm, continuous illuminations, output power 5 W, beam spot area at the target had 0.7 cm2, and an energy density had 643 J/cm2 delivered without delay after wounds procedure. Furthermore, the other half of the animals had been set up as a control group. Next, the animals have been divided into four groups interconnected to the healing time intervals. A repairing operation area has been uprooting and further stained by the immunohistochemistry method towards identifying the appearance of (IL-1β). Cold laser therapy has proficient to amplify the appearance of (IL-1β) near the beginning of healing stages plus boosting epithelialization remodeling procedure within one to two weeks of healing time. Cold laser therapy tested in this work resulted in enlarged expressions of (IL-1β) in the laser treatment group considerably next to one week of healing time, which has an effect on wound healing.
