Antioxidant and anti-rheumatoid activities of Cirsium japonicum leaf extract (CJLE) were investigated in this study. CJLE had similar DPPH radical scavenging activity and reducing power to ascorbic acid and several flavonoids. Rheumatoid arthritis (RA) is a chronic inflammatory tissue-destructive disease, partly related with functions of hyaluronidases (HAases) and collgenases. CJLE ($1,000\;{\mu}g/mL$) had approximately 60.7 and 31.9% inhibition of HAase and collagenase activity, respectively. Also, CJLE inhibited lipopolysaccharide (LPS)-induced nitrite production in a dose-dependent manner, and CJLE ($1,000\;{\mu}g/mL$) suppressed approximately 70% of LPS-induced nitrite production effectively in RAW 264.7 macrophage cells. CJLE had inhibitory effects on the adherence of monocytic THP-1 to human umbilical vein endothelial cell (HUVEC) monolayers to the basal level. Inhibitory effect of CJLE on the adhesion was caused by suppression of tumor necrosis factor-a-upregulated expression of vascular cellular adhesion molecule-1 (VCAM-1) and E-selectin. We expect that CJLE may alleviate the inflammatory process in rheumatoid synovium, and these findings will raise the possibility of the usage of C. japonicum as a traditional pharmaceutical of anti-rheumatoid arthritis.

Objectives : Degenerative arthritis arises from several physiological factors. The purpose of this study is to investigate the beneficial effects of Phyto-extract Complex (CME) on degenerative arthritis. Methods : CME is composed of extracts of mulberry (Morus alba L.) fruit, mulberry leaves and black beans (Glycine max (L.) Merr.). To measure the toxicity of CME, we performed the single-dose toxicity study. For the evaluation of its effects on degenerative arthritis, we examined the inhibition of cyclooxygenase-2 (COX-2) activity, using in vitro enzyme activity assay, the reduction of protein expression of COX-2, 5-lipoxygenase (5-LO), and inducible nitric oxide synthase (iNOS) in RAW264.7 cells which were stimulated by lipopolysaccharide (LPS). We also examined the serum level of prostaglandins (PGs) and injury of the knee joint cartilage, using animal model of degenerative arthritis induced by mono-sodium iodoacetate (MIA). Results : CME did not have any toxicity in single-dose toxicity study. The CME inhibited the activity of COX-2 and could reduce the protein expression of COX-2, 5-LO and iNOS in RAW264.7 cells. The CME also reduced the serum level of PGs and prevented from the cartilage injury of knee joint in animal model of degenerative arthritis induced by MIA. Conclusions : Taken altogether, the CME could be useful for the improvement of degenerative arthritis through its various anti-inflammatory activities and prevention from the cartilage injury of knee joint.

Objectives : Peroxynitrite (ONOO-), superoxide anion radical (?O2-) and nitric oxide (NO) are cytotoxic because they can oxidize several cellular components such as proteins, lipids and DNA. They have been implicated in the aging process, and age-related diseases such as Alzheimer's disease, rheumatoid arthritis, cancer and atherosclerosis. The aim of this study was to investigate Sabohwan's activity for scavenging ONOO- and its precursors. NO and ?02-. Methods : For this study, the fluorescent probes, namely 2',7'-dichlorodihydrofluorescein diacetate (DCFDA), 4.5-diaminofluorescein (DAF-2) and dihydrorhodamine 123 (DHR 123) were used. Results : Sabohwanblocked tert-butylhydroperoxide (t-BHP)-induced cell death in a dose-dependent fashion. It scavenged t-BHP-induced ONOO-, NO and ?O2- in YPEN cells. Sabohwan inhibited the generation of ONOO-, NO and ?O2- in the lipopolysaccharide (LPS)-treated mouse kidney postmitochondria both in vitro and in vivo. The lipid peroxide level increased and glutathione level decreased in the LPS-treated mice, whereas the ones in the Sabohwanadministered group among the LPS-treated mice reversed toward their natural levels. Conclusions : These results suggest that Sabohwanis an effective ONOO-, ?O2- and NO scavenger, and thereby it might have a potential role as a therapy against the aging process and age-related diseases.

Actinidia polygama has long been used in traditional Korean medicine to treat rheumatoid arthritis and gout. Although numerous chemical compounds in the fruit extracts of A. polygama have been characterized and their role in inhibiting nitric oxide (NO) production has been reported, the anti-inflammatory properties of A. polygama extracts remain to be explored. In this study, we investigated the in-vivo effect of A. polygama extract on lipopolysaccharide (LPS)-induced inflammation in BV-2 microglial cell lines. We discovered that 100% ethyl alcohol extract of A. polygama effectively attenuates the release of NO and is superior to both water extract and 50% ethanol extract. Using MTT assay, western blot, and ELISA on LPS-induced BV-2 microglial cells lines, we established the ability of A. polygama extract to markedly suppress the expressions of inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2), and pro-inflammatory cytokines, such as tumor necrosis factor alpha and interleukin-6. These results reveal that the anti-inflammatory property of A. polygama in BV-2 microglial cells is due to the downregulation of iNOS, COX-2, MAPK protein, and pro-inflammatory cytokines.

Periodontitis is a chronic inflammatory disease and gums pull away from the teeth and form spaces. The main goal of treatment is to control the infection and anti-inflammation. Eucommia ulmoides Oliv. Bark (EU) is a traditional Korean herbal used for the treatment of arthritis and hypertension. In the present study, we investigated the anti-inflammatory properties of EU in Porphyromonas gingivalis-LPS (LPS-PG) induced YD-38 epithelial cells. We observed significant inhibition of nitric oxide (NO) production and the expression of interleukin-8 (IL-8), interleukin-6 (IL-6), tumor necrosis factor alpha ($TNF-{\alpha}$), cyclooxygenase-2 (COX-2) in LPS-PG-induced YD-38 cells. These results support that EU has an anti-inflammatory effects for the treatment of periodontitis.

Objectives GyejigaChulBuTang (GCBT) is a prescription used to treat acute and chronic arthritis in Korea, China, and Japan. This study assessed the anti-inflammatory and anti-oxidant activities of GCBT on lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells. Methods Raw264.7 cells were pretreated with or without GCBT for 1 hour prior to incubation with LPS. Anti-inflammatory activity of GCBT was evaluated with reference to gene expression and production levels of proinflammatory cytokines ($TNF{\alpha}$, IL-$1{\beta}$, IL-6, GM-CSF and $INF{\gamma}$) and inflammatory mediators (iNOS, COX-2, NO and $PGE_2$). In addition, intracellular ROS generation and signal transduction of MAPK family, PI3K/Akt and $I{\kappa}B{\alpha}/NF{\kappa}B$ was investigated. Results Prior treatment with GCBT inhibited elevation of $TNF{\alpha}$, IL-$1{\beta}$, IL-6, GM-CSF, $INF{\gamma}$, NO and $PGE_2$, together with their cognate mRNAs in a dose-dependent manner. Intracellular ROS contents were similarly reduced. These effects were due to inhibition of LPS-induced phosphorylation of MAPK family, PI3K/Akt and $I{\kappa}B{\alpha}$ as well as nuclear translocation of $NF{\kappa}B$. Conclusions GCBT suppresses pro-inflammatory mediators. GCBT has potential in the treatment of juvenile rheumatoid arthritis associated with inflammation.
