Abstract :
The skin is one of the largest organs of the body and acts as a protective barrier against external harmful factors including microorganisms. It can be damaged and sometimes if the damage is too much, the hypoderm is also involved, so more time is needed for restoration. The purpose of this research is to investigate cedar plant on skin wound healing in NMRI laboratory mice. 24 mice with a weight of approximately 25-35 grams were bought and after wounding the skin on days 3, 6, 12, 21 they were treated with ointment prepared from cedar and oserin. Mice were randomly divided into three groups: sham, experimental 1, experimental 2. These groups were treated with oserin and Cedar ointment with a dose of 2 mg and 4 mg respectively. Wounds were measured after 3 weeks and their tissue was evaluated by hematoxylin-eosin staining. Biochemical indices of SOD, MDA and TAC were also investigated. Data analysis was done by SPSS version 22 software and Tukey's test. The wound size in Cedar 1 and 2 groups had a significant decrease compared to oserin (p < 0.05). The concentration of MDA in cedar groups 1 and 2 had a significant decrease compared to oserin (p < 0.05). In addition, the activity of SOD and TAC were significantly increased in cedar groups 1 and 2 compared to oserin (p < 0.05). Also, there was a significant increase in the thickness of epidermis and dermis in cedar 1 and 2 compared to oserin (p < 0.05). There was a significant increase in the number of fibroblasts and blood vessels in cedar 1 and 2 compared to oserin (p < 0.05). According to the results of the present study, it can be concluded that cedar extract was effective in wound healing by increasing SOD, TAC and decreasing MDA.
