Introduction: The aim of this work was to evaluate the effects of four different concentrations of Aloe vera extract on healing of second degree burns in male Wistar rats.

Materials and methods: By an experimental study 42 male Wistar rats were divided into 7 equal groups. The burn injury was made on the back of all rats, according to standard methods. The burned areas in the group1: were left without any intervention, group 2: were treated topically with eucerin, group 3: were treated with SSD and groups 4-7 were covered with 0.5%, 1%, 1.5%, 2% Aloe vera extract in eucerin (basal cream) twice a day, respectively. 21 days later the rats were sacrificed and samples of burnt skin tissue were collected for histological examinations. The parameters were evaluated to be considered for review included the number of hair follicles, sebaceous glands of angiogenesis, acute inflammation (severe infiltration of neutrophils) and the formation of epithelial layers.

Results: Diagram of healing levels and reduction rats of wounds' sizes in 3th week indicated that the former was reduced more significantly in groups 3, 6 and 7 than in groups 1 (P<0.005) and 2 (P<0.01). Histological findings showed that burn healing was significantly better in groups 6 and 7 than the groups 1 and 2 at the day 21.

Conclusion: It could be concluded that concentration of 1.5% and 2% of Aloe vera extract have an effective role in the treatment of burn wound healing.
