我们评估了日本传统配方 kigikenchuto (KKT) 在改良的大鼠压力负荷皮肤溃疡模型中的效果。将大鼠分为三组,口服 KKT 提取物组(250 或 500mg/kg/天,持续 35 天)和对照组。 KKT 缩短了愈合时间。免疫组织化学显示,KKT 在伤口愈合早期增加 CD-31 阳性血管,在早期增加 α-平滑肌肌动蛋白 (α-SMA-) 阳性成纤维细胞,在伤口愈合后期减少。通过蛋白质印迹,KKT 显示出在早期阶段减少炎症细胞因子(MCP-1、IL-1β 和 TNF-α)、在早期阶段减少血管内皮生长因子并在晚期增加血管内皮生长因子、调节细胞外蛋白基质(α-SMA、TGF-β1、bFGF、III 型胶原和 I 型胶原)表达的潜力。这些结果表明 KKT 可能通过减少炎症细胞因子、增加血管生成和诱导细胞外基质重塑来加速压疮愈合。
We evaluated the effect of kigikenchuto (KKT), a traditional Japanese formula, in a modified rat pressure-loading skin ulcer model. Rats were divided into three groups, KKT extract orally administered (250 or 500 mg/kg/day for 35 days) and control. KKT shortened the duration until healing. Immunohistochemically, KKT increased CD-31-positive vessels in early phase and increased α-smooth muscle actin-(α-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 (MCP-1, IL-1β, and TNF-α) 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 (α-SMA, TGF-β1, bFGF, collagen III, and collagen I). 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.
