Banhasasim-tang (BHSST) is a Korean traditional herbal formula comprising eight medicinal herbs. The aim of the present study was to investigate the anti-inflammatory effect of BHSST using macrophage and keratinocyte cell lines. First, we evaluated the effects of BHSST on inflammatory mediator and cytokine production in lipopolysaccharide- (LPS-) stimulated RAW 264.7 macrophages. BHSST markedly inhibited the production of nitric oxide (NO), prostaglandin E2 (PGE2), and interleukin- (IL-) 6. BHSST significantly suppressed the protein expression of toll-like receptor 4 (TLR4) and phosphorylated nuclear factor-kappa B (NF-κB) p65 in RAW 264.7 cells. Second, we examined whether BHSST influences the production of chemokines and STAT1 phosphorylation in tumor necrosis factor-α/interferon-γ TI-stimulated HaCaT keratinocytes. BHSST significantly suppressed the production of RANTES/CCL5, TARC/CCL17, MDC/CCL22, and IL-8 in TI-stimulated HaCaT cells. BHSST also suppressed TI-induced phosphorylation of STAT1 in HaCaT cells. These results suggest that BHSST may be useful as an anti-inflammatory agent, especially for inflammatory skin diseases.
百花散汤(BHSST)是一种由八种草药组成的韩国传统草药配方。本研究旨在通过巨噬细胞和角质形成细胞系研究 BHSST 的抗炎作用。首先,我们评估了 BHSST 对脂多糖(LPS)刺激的 RAW 264.7 巨噬细胞中炎症介质和细胞因子产生的影响。BHSST 显著抑制一氧化氮(NO)、前列腺素 E2(PGE2)和白细胞介素-(IL-)6 的产生。BHSST 显著抑制 RAW 264.7 细胞中 TLR4 和磷酸化核因子-κB(NF-κB)p65 的蛋白表达。其次,我们研究了 BHSST 是否影响肿瘤坏死因子-α/干扰素-γ(TI)刺激的 HaCaT 角质形成细胞中趋化因子的产生和 STAT1 磷酸化。BHSST 显著抑制 TI 刺激的 HaCaT 细胞中 RANTES/CCL5、TARC/CCL17、MDC/CCL22 和 IL-8 的产生。BHSST 还抑制了 TI 诱导的 HaCaT 细胞中 STAT1 的磷酸化。这些结果表明,BHSST 可用作抗炎剂,特别是用于炎症性皮肤病。
