Saengmaeksan (SMS) is a well known Korean traditional herbal prescription, which consists of 3 different herbs, Radix Ophiopogonis, Radix Ginseng, and Fructus Schisandrae. SMS has been commonly used in various disease including respiratory system and cardiovascular System in Korea. The objective of this study is to find out the improving effects of SMS against Dextran Sulfate Sodium (DSS)-induced ulcerative colitis. SMS reduced clinical signs of DSS-induced colitis, including body weight loss, shorten colon length, and increased disease activity index. The results showed that SMS significantly inhibited the activation of nuclear factor-${\kappa}B$ p65 in the colon tissues of DSS-treated mice. In addition, we observed that result showed that the levels of IL-6 in plasma were increased in DSS treated group compared to those of the normal group, but these increased levels were reduced by administration with SMS. Taken together, these findings suggest that SMS has improving effects on DSS-induced ulcerative colitis, which may explain its beneficial effect in the regulation of chronic intestinal inflammation.

KH-red ginseng/chlorella (KH-RG/C) is the mixed material of the Korean red ginseng powder (Panax ginseng, 75%) and extract of Chlorella vulgaris (25%). To evaluate the effects of KH-RG/C on endurance capacity and immune regulation, the forced swimming test (FST) was conducted. The immobility time in the FST was significantly decreased in KH-RG/C treated group compared with the DW-treated group at the 3 and 10 days, respectively. In the analysis of the blood biochemical parameters, KH-RG/C treatment significantly increased the glucose level. However, the lactic dehydrogenase level decreased. Although KH-RG/C increased aspartate aminotransferase, it was not different significantly. And KH-RG/C had no affects in the alanine aminotransferase, and blood urea nitrogen levels. In splenocytes and macrophages, KH-RG/C also did not affect the interleukin (IL)-2, IL-4, and IL-12 production. These results suggest that KH-RG/C may influence to immune regulation through increasing the physical endurance capacity without effect in activation of immune cells.

The molecular mechanisms control the function of PDL(periodonta1 ligament) cells and/or fibroblasts remain unclear. PDLsl7, PDL-specific gene, had previousely　identified the cDNA for a novel protein from cultured　PDL fibroblasts using subtraction hybridization between gingival fibroblasts and　PDL fibroblasts. The purpose　of this study was to determine the regulation by growth factors and cytokines on　PDLsl7 gene expression in　cultured human periodontal ligament cells and observe the immunohistochemical　localization of PDLsl7 protein in various tissues of mouse. Primary PDL fibroblasts isolated by scraping the root of the extracted human mandibular third molars. The cells were incubated with various concentration of human recombinant $IL-1{\beta}$, PDGF-BB and TGF\;${\beta}$ for 48h nd 2 weeks. At each time point total RNA was extracted and the levels of transcription ere assessed by reverse transcription-polymerase chain reaction (RT-PCR assay). polyclonal antiserum raised against PDLsl7 peptides, CLSVSYNRSYQINE and SEAVHETDLHDGC, were made, and stained the tooth, periodontium, developing bone, bone marrow and mid-palatal suture of the mouse. The results were as follows. 1. PDLsl7 mRNA levels were increased in response to PDGF (10ng/ml) and $TGF\;{\beta}$(20ng/ml) after treatment of the $IL-1{\beta}$, PDGF-BB and $TGF{\beta}$for 48 h. 2. PDLsl7 was up-regulated only by $TGF{\beta}$(20 ng/ml) after treatment of the $IL-1{\beta}$, PDGF-BB and $TGF\;{\beta}$ for 2 weeks and unchanged by the other stimulants. 3. PDLsl7 was a novel protein coding the 142 amino acid peptides in the ORF and the nucleotide sequences of the obtained cDNA from RT-PCR was exactly same as the nucleotides of the database. 4. Immunohistochemical analysis showed that PDLsl7 is preferentially expressed in the PDL, differentiating osteoblast-like cells and stromal cells of the bone marrow in the adult mouse. 5. The expression of PDLsl7 protein was barely detectable in gingival fibroblasts, hematopoetic cells of the bone marrow and mature osteocytes of the alveolar bone. These results suggest that PDLsl7 might upregulated by PDGF-BB or $TGF{\beta}$ and acts at the initial stage of differentiation when the undifferentiated mesenchymal cells in the bone marrow and PDL differentiate into multiple cell types. However, more research needs to be performed to gain a better understanding of the exact function of PDLsl7 during the differentiation of bone marrow mesenchymal and PDL cells.

Pinus densiflora root (PDR) is used as a medicinal plant. In this study, we investigated whether the PDR extract has anti-inflammatory activities. Cell viability assays showed that the extract was not toxic toward RAW 264.7 cells at concentrations up to $10{\mu}g/mL$. At $10{\mu}g/mL$, the extract decreased nitric oxide (NO) content to 40% of the control level. The protein expression of inducible nitric oxide synthase (iNOS), which generates NO, decreased with increasing concentrations of the extract. Prostaglandin $E_2$ ($PGE_2$) levels were significantly inhibited by over 50% in the presence of $10{\mu}g/mL$ of the extract. The protein expression of cyclooxygenase-2 (COX-2), which generates $PGE_2$, decreased with increasing concentrations of the extract. Proinflammatory cytokines, such as tumor necrosis factor-alpha ($TNF-{\alpha}$), interleukin-6 (IL-6), and $IL-1{\beta}$, were detected in RAW 264.7 cells after lipopolysaccharide (LPS) treatment. The extract did not affect the levels of $TNF-{\alpha}$ and IL-6, but it significantly inhibited the level of $IL-1{\beta}$. It also completely inhibited the transcription of nuclear factor-kappaB ($NF-{\kappa}B$). These results indicate that the PDR extract reduces inflammatory response-related proteins, such as NO, $PGE_2$, iNOS, and COX-2, in LPS-induced RAW 264.7 cells via the regulation of $NF-{\kappa}B$. Consequently, we have provided a mechanism to explain the anti-inflammatory effect of the PDR extract; that is, it exerts such an effect by regulating $NF-{\kappa}B$. The PDR extract can therefore be considered as an effective anti-inflammatory agent.

Background: Roles of immune reaction and toll-like receptor-4 (TLR-4) have widely been established in the pathogenesis of alcoholic liver disease (ALD). Methods: We evaluated the biologic efficacy of Korean Red Ginseng (KRG), urushiol, and probiotics (Lactobacillus rhamnosus R0011 and Lactobacillus acidophilus R0052) in mouse models of ALD. Sixty C57BL/6 mice were equally divided into six feeding groups for 10 weeks: normal diet, alcohol, control, alcohol + KRG, alcohol + urushiol, and alcohol + probiotics. Alcohol was administered via a LiebereDeCarli liquid diet containing 10% alcohol. TLR-4 expression, proinflammatory cytokines, and histology, as well as the results of liver function tests were evaluated and compared. Results: No between-group differences were observed with regard to liver function. TLR-4 levels were significantly lower in the KRG, urushiol, and probiotics groups than in the alcohol group ($0.37{\pm}0.06ng/mL$, $0.39{\pm}0.12ng/mL$, and $0.33{\pm}0.07ng/mL$, respectively, vs. $0.88{\pm}0.31ng/mL$; p < 0.05). Interleukin-$1{\beta}$ levels in liver tissues were decreased among the probiotics and KRG groups. The tumor necrosis factor-${\alpha}$ level of liver tissue was decreased in the KRG group. Conclusion: The pathological findings showed that alcohol-induced steatosis was significantly reduced by KRG and urushiol. As these agents improve immunologic capacity, they may be considered in potential anti-ALD treatments.

Gochujang, a traditional Korean food, is fermented by mixing red pepper powder, various grain, meju and salt. Changes in the kind of ingredients and fermentation method could increase health functionalities. In this study, in vivo anti-colitis effects of gochujang prepared with mixed grains, bamboo salt baked 3 times and meju starters on DSS-induced colitis in C57BL/6 mice were studied. We prepared gochujang prepared with mixed grains (MG), bamboo salt, and Aspergillus oryzae (A) and Baccillus subtilis (B) mixed starters (MG-AB) and gochujang prepared with MG, bamboo salt and A, B and Lactobacillus plantarum (L) mixed starters (MG-ABL). MG-AB and MG-ABL significantly increased body weight and colon length compared to the control (p<0.05). MG-ABL showed significantly decreased interleukin-6 (IL-6) expression in serum compared to the control and MG-AB group (p<0.05). MG-ABL also regulated mRNA and protein levels of pro-apoptotic Bcl-2-associated X protein (Bax) and anti-apoptotic B-cell lymphoma-2 (Bcl-2) in the mice colon tissue (p<0.05). Therefore, MG-ABL exhibited the increased anticolitis effects by inhibiting damage of colon tissue, probably by regulating a pro-inflammatory cytokine of IL-6 and regulated apoptosis related genes. These results indicated that gochujang changed with good ingredients and starters had colitis preventive effects and might be due to active compounds in mixed grain and bamboo salt, and produced by L during the fermentation of gochujang.

Objectives : The present study investigated inflammatory effect of Rheum undulatum L. in lipopolysaccharide-exposed rats and Raw 264.7 cells. Methods : Male rats weighting $185.39{\pm}8.21g$ fed basal diet for 1 week and 32 rats were divided into a control group and 3 experimental groups. We fed a control group of rats a basal diet and administered normal saline(100 mg/kg, 1time/1day) for 6 weeks. And we fed basal diet and administered an extract of Rheum undulatum L.(100 mg/kg, 200 mg/kg, 300 mg/kg, 1time/1day) to each experimental group of rats. We measured the plasma concentration of $IL-1{\beta}$($interleukin-1{\beta}$), IL-6 and $TNF-{\alpha}$(tumor necrosis $factor-{\alpha}$), liver cytokines, Raw 264.7 macrophages cytokines. Results : The plasma concentration of $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ peaked at 5h(hour) after LPS(lipopolysaccharides) injection, and the values of the Rheum undulatum L. extract groups were lower than those of the control group. In the increment of these cytokines concentration at 2h and 5h after LPS injection, the Rheum undulatum L. groups were lower than that of control group. The plasma concentration of IL-10 peaked at 5h after LPS injection, and the values of the Rheum undulatum L. extract groups were higher than those of the control group. In the increment of this cytokine concentration at 2h and 5h after LPS injection, the Rheum undulatum L. groups were higher than that of control group. Liver cytokines measurement was done at 5h after LPS injection. The concentration of liver $IL-1{\beta}$ and IL-6 in the Rheum undulatum L. groups was lower than that of the control group. The concentrations of liver $TNF-{\alpha}$, and IL-10 showed no significant differences among all the treatment groups. In the studies of lipopolysaccharide-exposed Raw 264.7 cells, the concentration of $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ in the lipopolysaccharide-exposed cells groups was higher than that of control group(normal group), and in the lipopolysaccharide-exposed cells groups, these values showed a tendency to decrease in the Rheum undulatum L. groups. The concentration of IL-10 in the lipopolysaccharide-exposed cells groups was higher than that of control group(normal group), and in the lipopolysaccharide-exposed cells groups, the values showed a tendency to increase in the Rheum undulatum L. groups. Conclusions : These results indicate that the Rheum undulatum L. extracts have an functional material for inflammatory activities.
