Low-Level Laser Therapy (Two Different Wavelengths 660nm and 820nm) Compared with Nigella Sativa Oil for Treatment of Burns in Rats

Abstract

The goal of this study was to assess the effect of LLLT and Nigella Sativa on the healing rate of a 2nd degree burn injury in
rate through histopathological analysis. For this, fifty male rats were divided for five groups G1 (laser 660nm),G2(laser
820nm), G3(Nigella Sativa), G4(sham positive), G5(control untreated). The burn was created on the back of the rats and
treatment of the experimental groups were (660nm for 20 seconds), (820nm for 20 seconds), (Nigella Sativa for continuous
ten days) respectively, the sacrifice of the animal were performed at the day 4, 7 and 10 with anesthetic over dose intra
peritoneal. The specimen collected was examined to evaluation healing rate lab animals in the group 1 (laser 660nm)
showed the best healing rate among the days of evaluation recorded in 10 days: downward hyperplasia of epidermis,
profuse collagen and scattered inflammatory cells. In conclusion, the LLLT with 660nm gave favourite healing process
among the other treatments of second-degree burns in rats.
