Abstract

Background: Burns is a major health problem due to severe side effects and limited financial resources. Some herbs are cheap and available, such as Arnebia euchroma can be effective treatment of burn wounds and reduce recovery time. The aim of this study was to evaluate the effect of Arnebia euchroma ointment on healing of deep seconddegree burn wound in rats. Methods: This experimental study was conducted in animal laboratory of Hazrat Fatemeh Hospital in 2015, Tehran. In this study 24 male Sprague-Dawley rats weighing approximately 300 to 350 g were selected. After general anesthesia, back of each rat was shaved with clipping device. Then second-degree burn with the area of 2×4 cm was induced on them. Rats were randomly divided into 2 groups, 12 in each. The surface of the wound in the first group was covered with Arnebia euchroma ointment and in the second group with Vaseline. Dressing was done daily until complete recovery and the wound healing process was monitored by photographing every five days. On day 20, the samples were sent for pathological evaluation of the amount of collagen and inflammatory cells. Results: Results showed that, during days from 5 to 15 the extent of the wounds reduced in both groups (P= 0.000). The reduction of wound size was significantly higher in Vaseline group compared to Arnebia euchroma ointment group (P= 0.040). The results of the pathological examination showed no significant difference in the amount of collagen and inflammatory cells in the two groups. Conclusion: It seems Arnebia euchroma ointment to some extent reduced the extent of the wound especially in superficial burns compared to other dressings. However, it is better to conduct more similar studies with a larger sample size and different method and change in timing of dressing. © 2018, Tehran University of Medical Sciences.
