摘要

Objective: To investigate the anti-inflammatory properties of methanolic extract of Clausena excavata in lipopolysaccharide(LPS)-activated macrophages(J774 A.1) and the effect on skin wound in a rat model through determining cytokine levels and gene expressions. Methods: The effects of methanolic extract of Clausena excavata on in vitro viability and TNF-α, IL-6, IL-10, and nitric oxide release by LPS-activated J774 A.1 cells were determined. In addition, relative expressions of BAX, BCL-2 and COX-2 genes were examined in healed wounds of rats. Results: The methanolic extract of Clausena excavata was not toxic to J774 A.1 cells at the highest dose of 400 μg/m L. It decreased levels of TNF-α and IL-6, while increasing IL-10 level in LPSactivated J774 A.1 cells and in the healed wounds of rats. The methanolic extract of Clausena excavata also inhibited nitric oxide production in LPS-activated J774 A.1 cells. The BAX and COX-2 genes were downregulated while the BCL-2 gene was upregulated in the healed wound of rats. Conclusions: The methanolic extract of Clausena excavata promotes wound healing via its anti-inflammatory and anti-apoptotic activities.
