چکیده
OBJECTIVE This study was designed to assess and compare the efficacy of accelerating burn healing in diabetic rats using low-power visible and invisible lasers. BACKGROUND DATA Low-level laser therapy (LLLT) has been used in a number of diabetic animal and human studies, with both positive and no effects. MATERIALS AND METHODS Male Sprague-Dawley rats were used in the study. Streptozotocin (70 mg/kg) was given for diabetes induction. A burn wound was created on the shaved back of the animals using a metal rod heated to 600 degrees C. The study was performed using 532-, 633-, 670-, 810-, and 980-nm diode lasers. Incident doses of 5, 10, 20, and 30 J/cm(2) and a treatment schedule of three times per week were used in the experiments. The burned areas on all rats were measured and plotted on a chart, and the slope values (mm(2)/d) and the percentages of burn healing were compared. RESULTS The percentage of burn healing on diabetic rats after LLLT was 78.37% for the visible lasers and 50.68% for the invisible lasers. There was a significant difference (p < 0.005) between visible lasers and invisible lasers in the percentage of burn healing on diabetic rats after laser therapy. CONCLUSION LLLT at the appropriate treatment parameters can accelerate burn healing on diabetic rats using both visible and invisible lasers. The effects of visible lasers were better than those of invisible lasers in accelerating burn healing on diabetic rats in this study.

OBJECTIVE We determined the effect of polychromatic light-emitting diodes (LED) in burn healing of non-diabetic and streptozotocin-induced diabetic rats. BACKGROUND DATA LEDs were used as the light source for phototherapy. MATERIALS AND METHODS The polychromatic LED is a cluster of 25 diodes emitting photons at wavelengths of 510-543, 594-599, 626-639, 640-670, and 842-879 nm with 272-mW ou...

متن کاملEffects of topical treatment of second-degree burn wounds with Lactobacillus acidophilus on the wound healing process in male rats
Despite preventive measures, incidence of burns is still one of the important medical problems. Nowadays, it has been suggested that some strains of probiotic bacteria have beneficial effects in treatment of skin injures like skin wounds. The aim of the present study was to evaluate the effects of Lactobacillus acidophilus on second-degree burn wounds in rats. Second-degree burn wounds were ind...
