Topical Application of Antrodia cinnamomea Ointment in Diabetic Wound Healing.

The number of diagnosed diabetic patients is increasing worldwide. Many people with diabetes develop wounds that are slow to, or never, heal, which can lead to serious health issues. Diabetes causes long-term excessive blood glucose buildup in human body, which leads to an over-reactive inflammatory response and excessive oxidative stress. As a result, varied wound healing effects were observed according to different circumstances and stage of healing. We used two diabetic wound animal models to analyze the wound healing effect of Antrodia cinnamomea ointment in either topical application and/or oral administration, and explored its mechanism by Western blot analysis. The results showed that topical Antrodia cinnamomea treatment can significantly promote wound healing. The increased expressions of angiopoietin 1 and angiopoietin 2 protein and reduction of CD68 expression were found around wound area. Simultaneous treatment of oral and topical Antrodia cinnamomea ointment did not show an accelerated healing effect in our animal model. This study is the first report to demonstrate the effect of topical application of Antrodia cinnamomea ointment on diabetic wounds healing, and its relationship with angiogenesis. This may also open a new field for future development and application of Taiwan Antrodia cinnamomea. [ABSTRACT FROM AUTHOR]
