Abstract
We compared the effects of rosmarinic acid and dexpanthenol in a rat experimental wound model. Twenty-four Wistar albino rats weighing 200-250 g were randomly divided into 3 groups. After 2-cm full-thickness skin defects were created, the wounds were washed with sterile 0.9% NaCl solution. After washing, the control group was left untreated, the second group received 5% dexpanthenol cream, and the third group received 10% rosmarinic acid cream. Before excision, the skin was evaluated macroscopically by measuring the reduction in wound size; after excision, histological examination (epithelization, inflammation, fibrosis, granulation) was performed. Macroscopic comparison of the wound sizes showed that group 3 showed a statistically significant difference in wound size reduction compared to the other two groups. Histopathological examination showed that there was no statistically significant difference between the groups. We found that the rosmarinic acid group had greater wound size reduction than the other two groups. However, epithelialization was detected in fewer cases. We believe that rosmarinic acid can be used as a topical cream for wound healing, as it leads to signif...
