Burn wound is a complex multi-factorial pathophysiology producing excruciating pain and psychological discomfort among patients, which imposes a major burden on the healthcare system. Multi-target therapy focuses on augmented healing by regulating different phases of tissue repair.

Recently, photobiomodulation (PBM)-induced wound healing has achieved profound impetus as a non-invasive, drug-free biophysical therapeutic approach. On the other hand, medicinal honey known to possess antibacterial and immunomodulatory properties and is being used as an effective treatment option for infected wounds.

The present study aimed to determine whether the combination of medicinal honey and PBM using superpulsed 904 nm laser treatment could additively accelerate full-thickness burn wound repair in rats.

Animals were randomly allocated into 4 experimental groups: control (C), PBM superpulsed 904 nm laser treated (PBMT), honey treated (HT) and combined treatment (CT). The dual treatment exhibited an enhanced wound area contraction and hexosamine content as compared to the other groups. Histopathological analysis revealed increased cellular proliferation, extracellular matrix accumulation and decreased inflammation in the CT group. Further, the CT group demonstrated synergistically attenuated inflammation, pain and enhanced cell adhesion, migration as evidenced by significantly reduced protein expression of TNF-α, NF-κB, IL-1β, COX-2, substance-P receptor and up-regulation of fibronectin, respectively as compared with the other groups.

Thus, the findings of present study signify that the combination of medicinal honey and PBMT accelerates the repair process of burn wounds.

The study showed that therapeutic efficacy of 904 nm superpulsed laser-mediated PBM augments in the presence of medicinal honey by enhancing cellular proliferation and attenuation of inflammation and pain in burn wound healing.
