Background : Recent studies have shown that stress fundamentally influences the functional modulation of organ and stress-related disease causes high morbidity and mortality rates. Objective : The present research investigated the effect of restraint stress on psychological and physiological responses. Results : Body weight and food intake were changed in stress group. Body weight has continuously decreased, and food intake has been slightly altered. As a result of measuring each tissue's weight, the liver and kidney's weight loss was greater than that of other organs. The lipid profile of stressed animals showed significant increases in cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels compared to control. As hepatic marker enzymes, serum glutamic pyruvic transaminase (GPT; alanine aminotransferase), glutamic oxalacetic transaminase (GOT; aspartate aminotransferase), and lactic dehydrogenase (LDH) were increased in the stress group. However, levels of serum cortisol and corticosterone did not affect. Results of the behavioral tests show that the stress group has increased activity, sluggish movements, and anxiety in the central part compared with the control group through the open field test. In the forced swim test, the stress group models had a longer duration of slowing movement, and its rate also increased. Also, in immunoblotting, stress increased the inflammatory factors Inducible Nitric Oxide Synthase (iNOS), cyclooxygenase-2 (COX-2) and activated the mitogen-activated protein kinase (MAPK) pathway. Conclusions : We observed that mouse model were affected behavioral response and liver injury when exposed to restraint stress, indicating the importance of the restraint stress in the development of psychological and physiological processes.

Backgrounds and Objectives: A fracture means a loss of continuity in the substance of bone. Bone differs from other musculoskeletal tissue due to its ability to repair and heal itself without leaving a scar. The cutter head has multinucleated osteoclast cells to resorb the dead bone. The tail, with its conical surface, is lined with osteoblast cells laying down new bone. The conjugation of fracture is a unique biological process regulated by a complex array of signaling molecules and proinflammatory cytokines. Pyritum, one of the important prescriptions in the oriental medicine, has been used for conjugation fracture. The purpose of this study is to evaluate the effects of administration of Pyritum on activation of osteoblast cells in human body & on tibia bone fracture in mice. Materials and Methods : Four weeks aged 30 female DBA mice were used for this study. They were divided three groups, normal group, control group(fracture elicitate mice: FE group) and experimental group(Pyritum administered mice group after fracture elicitation : PA group). Left tibia bones of mice in FE and PA groups were fractured by bone cutters. MG-63 cells in human body th Pyritum in the ratio of 1 mg/m${\ell}$, and the cells were further incubated for 24 hours. Activation of osteoblast was identified using osteopontin, FGF in vitro test. In vivo test, regeneration of fractured tibia through the morphological changes was observed, and also activation of inflammation through NF-${\kappa}$B p65, iNOS, COX-2, osteoblast through osteopontin, FGF and osteoblast's proliferation in each group was measured. Results and Conclusions : 1. In vitro test for activation of osteoblast cells in human body by Pyritum, osteopontin and FGF production were remarkably increased in Pyritum treated MG-63 cells. 2. In regeneration of fractured tibia by Pyritum, fractured area in external tibia morphology was decreased more in the PA group than that of the FE group. Osteogenesis in fractured area was increased more in the PA group than that of the FE group. Also, endochodrial ossification in central area of fracture and osteoid in lateral area of fracture were increased more in the PA group than those of the FE group. 3. In activation of inflammation by Pyritum administered, activation of NF-${\kappa}$B p65, increase of iNOS and COX-2 production were higher in the PA and the FE groups than those of the control group. Especially, the PA group showed higher activation and increase than those of the FE group. 4. In activation of osteoblast by Pyritum, increase of osteopontin, FGF and osteoblast's proliferation were higher in the PA and the FE groups than those of the control group. Especially, the PA group showed higher increase and proliferation than those of the FE group.

The purpose of this study was to examine the anti-inflammatory effects of ginger and processed (Beopje) ginger on colitis induced by 2.5% dextran sulfate sodium (DSS) in Balb/c mice. Beopje means a process that herbal medicines are treated by a specific Korean traditional method in order to obtain better pharmacological effects. Mice were fed saline or two different doses of ethanol extracts (ginger and processed (Beopje) ginger) once a day for 14 days. Colitis was induced from day 7 to 14 via administration of 2.5% DSS in drinking water. Experimental animals were divided into four groups: Nor (Normal, 200 ${\mu}L$ of saline without 2.5% DSS-treated group), Con (Control, 200 ${\mu}L$ of saline and 2.5% DSS treated group), G (500 mg/kg of ginger and 2.5% DSS treated group), and BG (500 mg/kg of Beopje ginger and 2.5% DSS treated group). Body weights of both ginger-administered groups increased compared to the control. Colon length increased to 7.6, and 8.0 cm in the G and BG groups, respectively, whereas that of control was 5.7 cm. Histological colon injury induced by DSS-induced colitis was reduced (P<0.05). In serum and DSS-treated colon tissues, mRNA expression levels of IFN-${\gamma}$, IL-6, TNF-${\alpha}$, and IL-12 of the Beopje ginger-treated group were significantly suppressed compared to those of the ginger-treated groups. Expression levels of iNOS and COX-2 of the Beopje ginger-treated group were significantly reduced compared to those of the ginger-treated groups (P<0.05), and BG showed stronger anti-inflammatory effects on colitis. These results indicated that ginger exerted anti-inflammatory effects on DSS-induced colitis in mice, and its effects could be increased through Beopje.

Fermentation characteristics and health functionalities of kimchi by inoculating kimchi lactic acid bacteria (LAB) starters were studied. We manufactured single LAB starter kimchi (Lactobacillus plantarum pnuK, Lactobacillus plantarum 3099K, Leuconostoc mesenteroides pnuK), mixed LAB starter kimchi (Lb. plantarum pnu/Leu. mesenteroides pnuK, Lb. plantarum 3099/Leu. mesenteroides pnuK) with inoculum size of $10^6$ CFU/g, as well as naturally fermented kimchi (NK), and fermented them for 6 days at $15^{\circ}C$. The pH and acidity of the early phase of fermentation were not different, but kimchi with the starters showed rapid changes in the pH and acidity from 2 days of fermentation. As the fermentation progressed, the level of total aerobic bacteria and Lactobacillus sp. increased similarly with or without Lb. plantarum (LP) inoculation. However, the level of Leuconostoc sp. was high in kimchi inoculated with Leuconostoc sp. starter. In the sensory evaluation test, kimchi with starters received higher overall acceptability scores than those of NK; mixed starter added kimchi earned the highest score. In DPPH and hydroxyl radical scavenging activity, kimchi with the starters exhibited higher activity than that of NK. In the MTT assay of HCT-116 and HT-29 human colon cancer cells, NK showed inhibition rates of 63.4 and 51.9%, but LPpnuK achieved 77.1 and 68.8%, respectively. This study showed that inoculating starters in kimchi increased in vitro antioxidant and anticancer activities, and single starter (LP) added kimchi revealed higher functionality than the kimchi with mixed starter. Kimchis with the starters effectively up-regulated the gene expressions of the pro-apoptotic gene of Bax, but down-regulated Bcl-2. They promoted expressions of p53 and p21, and suppressed expressions of inflammation-related genes, iNOS and COX-2, compared with NK. Taken together, it is expected that using starters may help manufacture kimchi with improved sensory quality and health functionality.

In order to compare the anti-inflammatory effects of five selected cereal grains-proso millet, hwanggeumchal sorghum, foxtail millet, barnyard millet, and adlay-the inhibitory activities of 80% ethanol (EtOH) extracts obtained from the individual grains on lipopolysaccharide (LPS)-induced nitric oxide (NO) generation were investigated in RAW264.7 cells. The EtOH extract of barnyard millet (Echinochloa crus-galli var. frumentacea) grains exhibited more potent anti-inflammatory activity than that of the other grains. When the EtOH extract of barnyard millet grains was sequentially fractionated with n-hexane, methylene chloride (MC), ethyl acetate (EtOAc), and n-butanol, the majority of the anti-inflammatory activity was detected in the MC fraction, followed by the EtOAc fraction. Pretreatment with the MC fraction caused downregulation of the expression levels of iNOS- and COX-2-specific transcripts and proteins, as well as proinflammatory cytokine gene transcripts (IL-$1{\beta}$, IL-6, and TNF-${\alpha}$) in LPS-stimulated RAW264.7 cells. Additionally, the MC fraction could suppress not only the LPS-induced nuclear translocation of cytosolic NF-kB, but also the LPS-induced activation of MAPKs, such as ERK, JNK, and p38MAPK. Further analysis of the MC fraction by HPLC identified kaempferol, biochanin A, and formononetin as the major phenolic components. Both kaempferol and biochanin A, but not formononetin, could exert anti-inflammatory effect at the same concentrations as those of the MC fraction. Consequently, these results indicate that kaempferol and biochanin A are among the most effective anti-inflammatory phenolic components in barnyard millet grains. This finding suggests that barnyard millet grains and the MC extract enriched in kaempferol and biochanin A could be beneficial functional food sources that have an anti-inflammatory effect.

As a research of inflammation inhibitory activity using natural resource, the inflammation inhibitory activity by purified active compound from Rhododendron mucronulatum flower was experimented. Rhododendron mucronulatum flower components were purified and separated with Sephadex LH-20 and MCI gel CHP-20 column chromatography, Purified compound was confirmed as myricetin by $^1H-NMR$, $^{13}C-NMR$ and Fast atom bombardment (FAB)-Mass spectrum to have inhibition activity on inflammatory factors secreted by Raw 264.7 cells in response to lipopolysaccharide stimulation. Myricetin inhibited nitric oxide (NO) expression in a concentration dependent manner, approximately 40% inhibition was observed at a concentration of $50{\mu}M$. The inhibition effect of myricetin on inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 protein expression was 20% and 80%, respectively, at a concentration of $25{\mu}M$. Myricetin also inhibited expression of the inflammatory cytokines, tumor necrosis factor $(TNF)-{\alpha}$, interleukin $(IL)-1{\beta}$, IL-6 and prostaglandin $E_2(PGE_2)$ in a concentration dependent manner; a concentration of $50{\mu}M$, 70%, 80%, 80% and 95% inhibition was observed, respectively. Therefore myricetin isolated from Rhododendron mucronulatum flowers is expected to have an anti-inflammatory effect in Raw 264.7 cell induced by lipopolysaccharides. The results can be expected myricetin from Rhododendron mucronulatum flower to use as functional resource for anti-inflammatory activity.

This study investigated the anti-inflammatory effects of wheat germ oil (WGO) on RAW 264.7 cells. It was shown that WGO had no cytotoxicity against the treated cells or negative effect on their proliferation. WGO suppressed nitric oxide (NO) secretion considerably and had inhibitory effects on the production of LPS-induced NO and pro-inflammatory cytokines (IL-6, TNF-α, and IL-1β). In particular, the IL-6 and TNF-α inhibition activities were over 90% at 100 μg/ml concentration of the oil. WGO also inhibited the LPS-induced expression of cyclooxygenase-2, inducible nitric oxide synthase, and nuclear factor-kappa B (NF-κB), and reduced the expression of phosphorylated ERK and JNK. Moreover, the croton-oil-induced edema in mouse ears was reduced by WGO, and no mortalities occurred in mice administered 5,000 mg/kg body weight of WGO over a 2-week observation period. In conclusion, these results provide evidence for the anti-inflammatory effect of WGO that likely occurs via modulation of NF-κB and the JNK/ERK MAPK signaling pathway.

This study aimed to investigate the anti-inflammatory effect of the ethanol extract from Chondrus ocellatus Holmes (COHEE) in RAW 264.7 cells and in a mouse ear edema model, by measuring the production of lipopolysaccharide-induced inflammatory response mediators. There were no cytotoxic effects on the proliferation of macrophages treated with COHEE compared with the control. COHEE inhibited the production of nitric oxide and pro-inflammatory cytokines [interleukin (IL)-6, tumor necrosis factor-α, and IL-1β]. The extract also reduced the expression of inducible nitric oxide synthase, cyclooxygenase-2, nuclear factor-κB p65, and phosphorylated mitogen-activated protein kinase in a dose-dependent manner. In the croton-oil-induced ear edema model, COHEE decreased the formation of mouse ear edema at the highest dose compared with the control, and histological analysis revealed that the epidermal/dermal tissue thickness and mast cell numbers were reduced. Therefore, these results suggest that COHEE may be a promising topical anti-inflammatory therapeutic material through its action of modulating NF-κB and the MAPK signaling pathway.

The anti-inflammatory effect of Sargassum coreanum ethanolic extract (SCEE) was investigated using lipopolysaccharide (LPS)-induced inflammatory responses in this study. It was shown that there was no cytotoxicity in the viability of macrophages treated with SCEE when compared to the control. The production of NO was considerably suppressed by SCEE, approximately up to 50% at 100 μg/ml. This significantly decreased levels of IL-6, TNF-α, and IL-1β. In addition, the expression of iNOS, COX-2, NF-κB was suppressed by SCEE treatment. In in vivo testing, the croton oil-induced mouse ear edema was attenuated by SCEE and there were no mortalities in mice administered with 5000 mg/kg body weight of SCEE over a 2 week observation period. From these results, SCEE inhibits the release of LPS-induced pro-inflammatory cytokines and mediators, suggesting that SCEE could be a potential agent for anti-inflammatory therapies.
