Six experimental groups were established, each containing 8 rats: a healthy group with no incision wounds, an incision-control group, an incision and TENS group, an incision and SS group, an incision and PI group, and an incision and lavender oil group. Experiments continued for 5 days, after which the skin in the excision area was removed. Tissue concentrations of epidermal growth factor (EGF) and platelet-derived growth factor (PDGF)-A were measured using enzyme-linked immunosorbent assay (ELISA). Tissue expressions of EGF, PDGF-A, and fibroblast growth factor (FGF)-2 were determined using immunohistochemistry. Wound closure progressed more rapidly in the TENS and lavender oil groups than in the control and other study groups. In particular, PDGF-A expressions in the dermis and EGF expression in the epidermis were significantly intense in the TENS group (P<0.05). In addition, ELISA levels of growth factors such as PDGF-A and EGF were significantly higher in TENS group compared to the control group (P<0.05). These immunohistochemical and ELISA results suggest that TENS may improve wound healing through increasing growth factors in the dermis and epidermis more than other topical applications. © 2013 Adalet Koca Kutlu et al.EnglishAll Open Access; Gold Open Access; Green Open Accessepidermal growth factorfibroblast growth factor 2growth factorlavender oilplatelet derived growth factor Apovidone iodinesodium chlorideanimal experimentanimal modelanimal tissuearticlecontrolled studydermisenzyme linked immunosorbent assayepidermisfemaleimmunohistochemistryintermethod comparisonmalenonhumanpriority journalprotein expressionrattranscutaneous nerve stimulationwound closurewound healingArticle10.1155/2013/361832
