标题：The Anti-inflammatory Effect of Gigukjiwhangwhangami through the Inhibition of Nuclear Factor-κB Activation in the Peripheral Blood Mononuclear Cells of Patients with Cerebral Infarction
摘要：The Korean genuine medicine “Gigukjiwhangwhangami (GJWGM)” has long been used for various cerebrovascular diseases. However, the exact mechanism that accounts for the anti-inflammatory effect of GJWGM is not completely understood. The aim of the present study is to elucidate how GJWGM modulates the inflammatory reaction in lipopolysaccaride (LPS)-stimulated peripheral mononuclear cells from patients with cerebral infarction. Production of cytokine was measured by the ELISA and RT-PCR method. The level of nuclear factor-kappaB (NF-κB)/ Rel A protein and NF-κB DNA binding activity were determined by the Western blot analysis and TF-EIA method. We showed that GJWGM inhibited the production of tumor necrosis factor (TNF)-α, interleukin (IL)-1α, IL-6, and IL-8 induced by LPS in dose dependent manner ( p <0.05). Maximal inhibition rate of TNF-α, IL-1β, IL-6 and IL-8 production by GJWGM was about 54.34%, 41.37%, 44.04%, and 54.46%, respectively. GJWGM inhibited the TNF-α and IL-8 mRNA expression. In addition, we showed that the inhibitory mechanism of GJWGM is through the suppression of NF-κB pathway. Our study suggests that an important molecular mechanism by GJWGM reduce inflammation, which may explain its beneficial effect in the regulation of inflammatory reactions.
