This study was aimed to verify anti-inflammatory activity of fermented Sargassum siliquanstrum with lactic acid bacteria. Anti-inflammatory activities were compared by measuring the amount of nitric oxide (NO) in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages and suppressive effect on inducible nitric oxide synthase (iNOS) expression in stably transfected RAW 264.7 cells. Inhibitory activities of NO production and iNOS expression were measured after confirmation of NO radical scavenging activities. Fermentation increased NO radical scavenging activities from 7.6% to 15.2% compared to non-fermented condition, and fermentation with Lactobacillus sp. SH-1 was the most efficient. Fermentation without algal debris showed better NO radical scavenging activities than that with debris. Fermentation with Lactobacillus sp. SH-1 also showed the highest NO production inhibitory activity (64.1%) in LPS-stimulated RAW 264.7 cells. LPS-induced iNOS expression was diminished to 28.6, 35.6, 49.4 and 58.5 at 50, 100, 500 and 1,000 μg/ml, respectively, by fermentation with Lactobacillus sp. SH-1. According to MTT assay, fermented S. siliquanstrum did not influence the cell viability at all concentrations tested, meaning no or less cytotoxicity. These results suggest that S. siliquanstrum has NO radical scavenging activity and anti-inflammatory activity. Thus biological activities of S. siliquanstrum were upgraded by fermentation, which could be used for the development of functional foods.

In the current study, antioxidant properties of extracts from different parts of Taraxacum officinale were determined by measuring the radical scavenging activity of 1,1-diphenyl-2-picryl hydrazyl(DPPH) and 2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). The antioxidant activity of aerial and root parts of this plant was measured in extracts obtained from various solvents, e.g., water, 50, 70, 100% ethanol, and hot-water. The hot-water extracts had the highest radical scavenging activities. A further study was conducted to determine the total antioxidant activity of hot-water extract fractions obtained from different solvents, e.g., chloroform, ethyl acetate, n-butanol, and water. The ethyl acetate fraction of this extract displayed the strongest DPPH and ABTS radical scavenging activity and the highest total phenolic contents. The inhibitory effect of individual solvent fractions on the production of nitric oxide in LPS-stimulated RAW 264.7 cells was measured. The results indicated that the ethyl acetate fraction of aerial and roots part extracts significantly reduced nitric oxide productions.

Objective : This study was performed to investigate the anti-fibrogenic effect and changes of inflammation-related genes by YBR I and YBR II (YBR I: Arteisiae Capillaris Herba, Atractylodis Rhizoma Alba, Hoelen/ YBR II: YBR I +Sanguisorbae Radix, Biotae Cacumen, Cirsii Japonici Herba) on HSC(hepatic stellate cells)-T6 and TAA-induced rat liver tissue. Materials and Methods : HSC-T6 were treated with various concentrations of distilled-water extract YBR I and YBR II extract for 24, 48 and 72 hours. After the treatment, cell viability, proliferation, procollagen levels and IL-6 levels were measured by using MTT Assay, BrdU Assay, Procollagen Type 1 C-peptide EIA kit, and Murine IL-6 ELISA Development kit. Rat liver fibrosis was induced by intraperitoneal TAA injection of 150mg/kg 3 times a week for 6 weeks. After the treatment, body weight, liver & spleen weights, liver function test, complete blood cell count and change of portal pressure were studied. In addition, gene expressions of ASMA, IL-6, MMP-2, TIMP-1 and TIMP-2, all of which are known to be associated with liver fibrosis, were analyzed by using Real-Time PCR. After YBR I and YBR IItreatment, percentages of collagen in TAA-induced rat liver tissue were measured. Results : The viability and proliferation of the HSC-T6 decreased as the concentration increased. The production of procollagen decreased as the concentration increased. The production of IL-6 was little influenced by YBR I and YBR II. There was no difference in rat body weight between the TAA-only group and the YBR groups. Compared with rat liver weight of TAA-only group, that of the YBR groups increased. In the YBR I group, the serum level of AST elevated by TAA injection significantly decreased and in the YBR I and II group, the serum level of ALP and ALT elevated by TAA injection decreased. In the YBR I group, white blood cell count elevated by TAA injection decreased but platelets increased. In the YBR I group, the portal pressure elevated by TAA injection significantly decreased. Decreases in the gene expression of ASMA and MMP-2 were observed in the YBR I group. The gene expression of IL-6 was little influenced by YBR I and YBR II -treated groups. In the histological finding, TAA injections caused severe fibrosis, but YBR I and YBR II treatment significantly reduced the amounts of hepatic collagens. Conclusions : These results suggest that YBR I and II have inhibitory effects on the hepatic fibrogenesis.

After treatment with CHP, safety in cytotoxicity, heavy metal toxicity, production of reactive oxygen species(ROS), nitric oxide (N0) and proinflammatory cytokine IL-Ib, TNF-a, IL-6 in RAW 264.7 cells. Serum total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride, insulin, GLP-1, glucose, food intake, body weight, organ weight, AST, ALT, ALP, BUN, creatine and histologic change of liver and aorta were measured in db/db mouse after oral administration of CHP. CHP showed safety in cytotoxicity and toxicity of liver and kidney for logn time administration. CHP increased the DPPH and ABTS radical scavenging activity. CHP showed significant inhibitory effect on reactive oxygen species (ROS), and showed inhibitory effect on nitiric oxide(NO) compared to control group. CHP decreased cytokine IL-6 production significantly, and decreased IL-1β and TNF-α compared to control group. CHP decreased body and organ weitht, intake food, and glucose levels compared to control group. CHP decreased total cholesterol and triglyceride significantly, and decreased LDL-cholesterol levels and increased HDL-cholesterol levels compared to control group. CHP decreased atherogenic index and cardiac risk factor significantly. CHP increased serum insulin and GLP-1 compared to control group. In histologic examination, lipophagy in the liver and aorta decreased in CHP treated mice and the cell was regular and boundary of vessel wall was clear compared to control group. These results suggest that CHP is effective in antioxidation activity and treatment and prevention of hyperlipidemia, atherosclerosis, diabetes, ischemic heart disease, stroke and other cardiocerebrovascular disease.

Objectives : Seungmagalgeun-tang (SMGGT) is traditional medicine widely used for inflammatory disease and flu. But SMGGT exhibits potent anti-inflammatory activity with an unknown mechanism. To elucidate the molecular mechanisms of SMGGT water extract on pharmacological and biochemical actions in inflammation, we examined the effect of SMGGT on pro-inflammatory mediators in Phorbol-12-myristate-13-acetate (PMA)+A23187-stimulated mast cells. Methods : In the present study, pro-inflammatory cytokine production was determined by performing enzyme-linked immunosorbent assay (ELISA), reverse transcription polymerase chain reaction (RT-PCR), and western blot analysis to measure the activation of MAPKs. Cells were treated with SMGGT 1 h prior to the addition of 50 nM of PMA and $1{\mu}M$ of A23187. Cell viability was measured by MTS assay. The investigation focused on whether SMGGT inhibited the expressions of interleukin-6 (IL-6), interleukin-8 (IL-8) and mitogen-activated protein kinases (MAPKs) in PMA+A23187-stimulated mast cells. Results : SMGGT has no cytotoxicity at examined concentration (100, 250, and $500{\mu}g/ml$). Also, gene expression of IL-6 and IL-8 in HMC-1 cells stimulated by PMA+A23187 was down regulated by SMGGT. Furthermore, SMGGT suppressed the PMA+A23187-induced phosphorylation of extracellular signal-regulated kinase (ERK) and c-jun N-terminal Kinase(JNK). But, SMGGT could not regulate phosphorylation of p38 MAPK. Conclusions : These results suggest that SMGGT has inhibitory effects on PMA+A23187-induced IL-6 and IL-8 production. These inhibitory effects occur through blockades on the phosphorylation of ERK and JNK.

Antimutagenicity of milk cultured with lactic acid bacteria isolated from dadih on the mutagenicity of heated salty and sweet tauco was examined using streptomycin dependent (SD) 510 strain of Salmonella typhimurium TA 98 as a tester culture. Cultured milk samples exhibited widely antimutagenic activity against mutagenic heated salty and sweet tauco. Lc. lactis subsp. lactis R-22, Lc. lactis subsp. casei R-35, Lc. lactis subsp. casei R-52 and E. faecalis subsp. liquefaciens R-55 exhibited no inhibitory effect on the mutagenic heated salty tauco. Mutagenicity of heated sweet tauco was inhibited by cultured milks stronger than that of heated salty tauco. Milk cultured with Lc. lactis subsp. cremoris R-48, Leuc. mesentroides R-51 and Lc. lactis subsp. casei R-68 showed high inhibition against the mutagenicity of both heated salty and sweet taucos. Antimutagenic activity of the cultured milks against mutagenic heated tauco was attributed to the bacterial cells. Among the three strains which showed high antimutagenicity, only Leuc. mesentroides R-51 was tolerant to both acid and bile; so this strain can be used as probiotic in preventing the occurrence of mutagenesis caused by mutagenic heated food like tauco.

The anti-Helicobacter pylori activity, cytotoxicity, and anti-inflammatory activity of white ginseng extract (WGE) were investigated in vitro in this study. The antimicrobial effects of WGE toward H. pylori strains 52 J99, SSI, and 51 were tested using the disk diffusion method. Among these H. pylori strains, H. pylori 52 was the most sensitive, having the largest inhibition zone (19 mm), followed by J99, SSI, and 51. The zone of inhibition due to WGE increased significantly with increasing dosage. The cytotoxicity of WGE toward the human cancer cell lines A-549 (human lung carcinoma), HEC-1-B (human endometrial adenocarcinoma), HeLa (human uterin adenocarcinoma), and SW-156 (human kidney carcinoma) was measured using the 3-(4,5-dimethylthizol-2-yl)-2,5-diphenylate-tetrazolium bromide (MTT) assay. WGE exhibited an inhibitory effect on cell growth at 2.0 mg/mL for all tumor cell lines. An analysis of anti-inflammatory activity using the RAW 264.7 cell line showed that the inhibition of nitric oxide (NO) production increased as the WGE content increased. These results demonstrate the potential of WGE to be used as a health-promoting substance.

The current work was designed to assess novel pharmacological activities of 4-hydroxybenzaldehyde (HD), a major phenolic constituent of various natural products of plant origin, such as Gastrodia elata Blume. HD exhibited a significant inhibition in the chick chorioallantoic membrane (CAM) angiogenesis. HD also displayed an inhibitory effect in acetic acid-induced permeability in mice. Anti-nociceptive activity of HD was convinced using the acetic acid-induced writhing test in mice. HD was able to suppress production of nitric oxide (NO) and induction of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in the lipopolysaccharide (LPS)-activated RAW264.7 macrophages. HD also diminished the reactive oxygen species (ROS) level elevated in the LPS-activated macrophages. In brief, HD exhibits anti-angiogenic, anti-inflammatory and anti-nociceptive activities possibly via down-regulating iNOS and/or COX-2, which may be partly responsible for pharmacological efficacies of various natural products.
