Influence of Aloe Vera gel on dermal wound healing process in rat.

In this topical study the influence of Aloe Vera, on the wound healing process was investigated in 63 male rats with microscopic and cell count methods. On the day of surgery a round wound, of diameter 20 mm, was created on the back of rats necks under sterile conditions. The surgery day was determined as day zero (0). Then the rats were divided randomly into control and experimental groups 1 and 2. Animals in each group were sub-divided to three smaller groups, investigated every 4, 7, and 14 days. From day 0, wound surfaces were covered with gel once daily in experimental group 1 and twice daily, for 12 h interval, in experimental group 2. Each rat received 30 g of the gel. The wound surface and healing were assessed on days 4, 7, and 14, and then a sample from the wound was prepared and investigated microscopically. The results show that the number of neutrophil, macrophage, and fibroblast cells and the wound thickness in the control group were statistically different from the experimental groups. It was found that the wound diameter thickness in the experimental group was greatly lower due to twice administration of gel and the power of wound healing was more than other groups.
