Background and Objective: Luffae Fructus Retinervus (LFR) is used for investigating symptoms of inflammation. We have evaluated the anti-inflammatory effect of LFR by analyzing the expression of pro-inflammatory cytokines. Materials and Methods : We differentiated THP-l cells into macrophage-like cells by treatment with PMA. Inflammation was induced by treatment with LPS and PMA. We determined the safe concentration of LFR by using the MTS and MTT assays and using PD 98059 as a negative control for comparison of the anti-inflammatory effect of LFR. Results : The MTS and MTT analysis showed that the cell survival rate was >80% within the LFR concentration range of 10-100 ng/ml and began to decrease to >80% at 1 ${\mu}g/ml$. By RT-PCR analysis, the gene expression of TNF-${\alpha}$, IL-8, TGF-${\beta}$, IL-6, IL-${\beta}$1, and IL-10 levels were down-regulated when monocyte-derived macrophages were treated with concentrations of LFR between 10 ng/mL and 100 ng/mL. Conclusion : We conclude that LFR exerts an anti-inflammatory effect by inhibiting the expression of pro-inflammatory activity. The results suggest a promising way to treat general inflammatory diseases.

Membranous nephropathy(MN) is the most common cause of adult nephrotic syndrome worldwide. But treatment of MN is not defined. This study was to evaluate the effects of Lonicerae Flos Extract(LFE) on the MN induced by cBSA in mice. Mice were divided into 4 groups. The first group named for 'Normal' was injected with a saline solution. The second group named 'Control' treated with cBSA(10 mg/kg i.p) only. The third group named 'LFE-250', treated with cBSA(10 mg/kg i.p) and LFE(250 mg/kg, p.o). The fourth group named 'LFE-500'treated with cBSA(10 mg/kg i.p) and LFE(500 mg/kg, p.o). After cBSA and LFE treatment for 4 weeks, we measured change of body weight, 24hrs proteinuria, serum albumin, total cholesterol, triglyceride, BUN, creatinine, TNF-$\alpha$, IL-6, IL-$1{\beta}$, IL-10, IFN-$\gamma$, IgA, IgM and IgG levels. The morphologic changes of renal glomeruli were also observed with a light microscope. The levels of 24 hrs proteinuria, total cholesterol, IgG , IgM, IgA, IL-6 were significantly decreased in both LFE groups. The level of triglyceride, IL-$1{\beta}$ was significantly decreased in LFE-500 group. The level of Albumin was significantly increased in LFE-250 group. The level of TNF-$\alpha$, IFN-$\gamma$ were significantly decreased in LFE-250 group. The mRNA expression of IL-$1{\beta}$ in splenocytes was consideraly decreased in LFE-500 group. In histological findings of kidney tissue, thickening of GBM decreased in both LFE groups. This study shows that the LFE might be effective for treatment of MN. More clinical data and studies are to be done for efficient application.

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.

Bamboo salt, a Korean folk medicine, is prepared with solar salt (sea salt) and baked several times at high temperatures in a bamboo case. In this study, we compared the preventive effects of bamboo salt and purified and solar salts on hepatic damage induced by carbon tetrachloride in Sprague-Dawley rats. Compared with purified and solar salts, bamboo salts prevented hepatic damage in rats, as evidenced by significantly reduced serum levels of aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase (P < 0.05). Bamboo salt (baked $9{\times}$) triggered the greatest reduction in these enzyme levels. In addition, it also reduced the levels of the proinflammatory cytokines interleukin (IL)-6, interferon (IFN)-${\gamma}$, and tumor necrosis factor (TNF)-${\alpha}$. Histopathological sections of liver tissue demonstrated the protective effect of bamboo salt, whereas sections from animals treated with the other salt groups showed a greater degree of necrosis. We also performed reverse transcription-polymerase chain reaction and western blot analyses of the inflammation-related genes iNOS, COX-2, TNF-${\alpha}$, and IL-$1{\beta}$ in rat liver tissues. Bamboo salt induced a significant decrease (~80%) in mRNA and protein expression levels of COX-2, iNOS, TNF-${\alpha}$, and IL-$1{\beta}$, compared with the other salts. Thus, we found that baked bamboo salt preparations could prevent $CCl_4$-induced hepatic damage in vivo.

Background: Red-fleshed sweet orange juice (ROJ) comes from a new variety of citrus cultivated in Brazil that contains high levels of ${\beta}$-carotene and lycopene, and similar amounts of hesperidin (HSP) and nutrients, equivalently to blond orange juice (BOJ). Such bioactive compounds are associated with chemopreventive actions in several cancer cell lines. The purpose of this study was to examine the cytotoxicity, cell cycle, apoptosis, and cytokine secretion after BOJ, ROJ, and HSP treatment of a novel T acute lymphoblastic leukemia cell line, Loucy. Materials and Methods: Loucy cells were incubated for 24-h with BOJ, ROJ, and HSP, and the viability was measured using trypan blue. Cell cycling and apoptosis were assessed by propidium iodide (PI) and annexin V-FITC/PI flow cytometry, respectively. Secretion of cytokines $IL-1{\alpha}$, $IL1-{\beta}$, IL-2, IL-4, IL-6, IL-10, IL-17A, $IFN{\gamma}$, $TNF{\alpha}$, $TGF{\beta}$, $MIP{\alpha}$, and $MIP{\beta}$ was determined by ELISA array. Results: BOJ and ROJ treatments promoted Loucy cell cytotoxicity. Additionally, BOJ induced cell cycle arrest in the G0/G1 phase, and decreased the cell accumulation in the G2/M. ROJ decreased only the G0/G1 fraction, while HSP did not change the cell cycle. BOJ led to apoptosis in a different fashion of ROJ, while the first treatment induced apoptosis by increase of late apoptosis and primary necrotic fractions, the second increased early and late apoptosis, and primary necrotic fraction compared to positive controls. HSP had no effect on apoptosis. IL-6 and IL-10 were abrogated by all treatments. Conclusions: Taking together, these results suggest potential chemopreventive effects of BOJ and ROJ on Loucy cells.

Pretreatment of low-dose lipopolysaccharide (LPS) induces a hyporesponsive state to subsequent secondary challenge with high-dose LPS in innate immune cells, whereas super-low-dose LPS results in augmented expression of pro-inflammatory cytokines. However, little is known about the difference between super-low-dose and low-dose LPS pretreatments on immune cell-mediated inflammatory and hepatic acute-phase responses to secondary LPS. In the present study, RAW 264.7 cells, EL4 cells, and Hepa-1c1c7 cells were pretreated with super-low-dose LPS (SL-LPS: 50 pg/mL) or low-dose LPS (L-LPS: 50 ng/mL) in fresh complete medium once a day for 2~3 days and then cultured in fresh complete medium for 24 hr or 48 hr in the presence or absence of LPS ($1{\sim}10{\mu}g/mL$) or concanavalin A (Con A). SL-LPS pretreatment strongly enhanced the LPS-induced production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6, TNF-${\alpha}$/IL-10, prostaglandin E2 ($PGE_2$), and nitric oxide (NO) by RAW 264.7 cells compared to the control, whereas L-LPS increased IL-6 and NO production only. SL-LPS strongly augmented the Con A-induced ratios of interferon (IFN)-${\gamma}$/IL-10 in EL4 cells but decreased the LPS-induced ratios of IFN-${\gamma}$/IL-10 compared to the control, while L-LPS decreased the Con A- and LPS-induced ratios of IFN-${\gamma}$/IL-10. SL-LPS enhanced the LPS-induced production of IL-6 by Hepa1c1c-7 cells compared to the control, while L-LPS increased IL-6 but decreased IL-$1{\beta}$ and C reactive protein (CRP) levels. SL-LPS pretreatment strongly enhanced the LPS-induced production of TNF-${\alpha}$, IL-6, IL-10, $PGE_2$, and NO in RAW 264.7 cells, and the IL-6, IL-$1{\beta}$, and CRP levels in Hepa1c1c-7 cells, as well as the ratios of IFN-${\gamma}$/IL-10 in LPS- and Con A-stimulated EL4 cells compared to L-LPS. These findings suggest that pre-conditioning of SL-LPS may contribute to the mortality to secondary infection in sepsis rather than pre-conditioning of L-LPS.

BACKGROUND/OBJECTIVES: Colitis is a serious health problem, and chronic obesity is associated with the progression of colitis. The aim of this study was to determine the effects of natural raw meal (NRM) on high-fat diet (HFD, 45%) and dextran sulfate sodium (DSS, 2% w/v)-induced colitis in C57BL/6J mice. MATERIALS/METHODS: Body weight, colon length, and colon weight-to-length ratio, were measured directly. Serum levels of obesity-related biomarkers, triglyceride (TG), total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), insulin, leptin, and adiponectin were determined using commercial kits. Serum levels of pro-inflammatory cytokines including tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin (IL)-$1{\beta}$, and IL-6 were detected using a commercial ELISA kit. Histological study was performed using a hematoxylin and eosin (H&E) staining assay. Colonic mRNA expressions of TNF-${\alpha}$, IL-$1{\beta}$, IL-6, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) were determined by RT-PCR assay. RESULTS: Body weight and obesity-related biomarkers (TG, TC, LDL, HDL, insulin, leptin, and adiponectin) were regulated and obesity was prevented in NRM treated mice. NRM significantly suppressed colon shortening and reduced colon weight-to-length ratio in HFD+DSS induced colitis in C57BL/6J mice (P < 0.05). Histological observations suggested that NRM reduced edema, mucosal damage, and the loss of crypts induced by HFD and DSS. In addition, NRM decreased the serum levels of pro-inflammatory cytokines, TNF-${\alpha}$, IL-$1{\beta}$, and IL-6 and inhibited the mRNA expressions of these cytokines, and iNOS and COX-2 in colon mucosa (P < 0.05). CONCLUSION: The results suggest that NRM has an anti-inflammatory effect against HFD and DSS-induced colitis in mice, and that these effects are due to the amelioration of HFD and/or DSS-induced inflammatory reactions.
