| Research Abstract |
We evaluated the effect of kigikenchuto(KKT), a traditional Japanese formula, in a modified rat pressure-loading skin ulcer modelKKT shortened the duration until healing. Immunohistochemically, KKT increased CD-31-positive vessels in early phase, and increased a-smooth muscle actin(a-SMA)-positive fibroblastic cells in early phase and decreased them in late phase of wound healing. By Western blotting, KKT showed the potential to decrease inflammatory cytokines in early phase, decrease vascular endothelial growth factor in early phase and increase it in late phase, and modulate the expression of extracellular protein matrix. These results suggested the possibility that KKT accelerates pressure ulcer healing through decreases of inflammatory cytokines, increase of angiogenesis, and induction of extracellular matrix remodeling.
