Amorphous silica particles, whose applications are increasing in many biomedical fields, are known to be less toxic than crystalline silica. In this study, the inflammatory effects of amorphous silica nanoparticles were investigated using 30-nm amorphous silica nanoparticles and human peripheral blood mononuclear cells (PBMCs) or purified monocytes. As a result, production of IL-$1{\beta}$ and IL-8 were increased. In addition, the mitochondrial reactive oxygen species (ROS) was detected, which may lead to mitochondrial membrane disruption. Most importantly, inflammasome formation was observed. Therefore, these results provide immunological information about amorphous silica nanoparticles and suggest that amorphous silica nanoparticles can evoke innate immune reactions in human monocytes through production of IL-$1{\beta}$ and IL-8.

Ginger(Zingiber officinale Roscoe) has long been used as a food source in Korea, and it is widely used as a dietary condiment throughout the world. The present study focused on the immunomodulative effects of ginger extracts via in vitro experiments. To identify the immune-activation fractions of the plant, we performed the systematic fractionation of ginger with methanol, hexane, chloroform, butanol and water for separation and refining. The results showed that the chloroform fraction had the highest immune cell activation properties. In conclusion, this study suggests that ginger extracts may enhance immune function by regulating the splenocyte proliferation as well as the cytokine production capacity of activated macrophages.

This study was performed to define the cytotoxicity and the anti-inflammatory action of Pulsatilla koreana extracts. To analyze cytotoxic effects, gingival and periodontal ligament fibroblasts were used, and anti-inflammatory actions related to reduction of $IL-1{\beta}$ and $PGE_2$ production were performed in vitro, for the suggestion of efficacy and safety on periodontal therapeutic use of Pulsatilla koreana extracts. We extracted ethylacetate and butylalcohol from well-dried and ground Pulsatilla koreana throughout multiple processing, then used different concentration solution(0.1 %, 0.2 %, 0.4 %, 0.01 %, 0.02 %, 0.04 %, 1 %, 2 %) of ethylacetate and butylalcohol extracts to examine eytotoxic effects and anti-inflammatory actions Cytotoxic effects were examined by ELISA reader using MTT(Methyl Thiazol-2-YL-2, 5-diphenyl Tetrazolium bromide)solution following culture of human gingival and periodontal ligament fibroblasts. Synthesis of $IL-1{\beta}$was examined by $IL-1{\beta}$ enzyme-immunoassay(EIA)system after separation and culture of monocyte, and $PGE_2$ was examined by $PGE_2EIA$ system after culture of gingival fibroblasts. The results were as follows: 1. In the MTT test of gingival fibroblasts, the change of optical density was decreased significantly at 2 % of butylalcohol extracts and 0.04 %, 0.1 %, 0.2 %, 0.4 %, 1 %, 2 % of ethylacetate extracts.(p<0.05) 2. In the MTT test of periodontal ligament cells, the change of optical density were not differ significantly. but butylalcohol and ethylacetate extracts except from butylalcohol 0.01 % showed high cell cytotoxity. 3. Both ethylacetate and butylalcohol extracts from Pulsatilla koreana inhibited the synthesis of $IL-1{\beta}$and inhibition effect of ethylacetate extracts were higher than butylalcohol extracts. 4. Both ethylacetate and butylalcohol extracts from Pulsatilla koreana inhibited the synthesis of $PGE_2$, and ethylacetate extracts were higher than butylalcohol extracts. In conclusion, ethylacetate and butylalcohol extracts from Pulsatilla koreana showed little cell cytotoxity for gingival and periodontal ligament fibroblasts, and the inhibition of $IL-1{\beta}$ and $PGE_2$ sysnthesis, therefore it is considered that these extracts can be developed as the therapeutics of the periodontal disease.

Objectives The purpose of this study was to evaluate the effect of Jeopgolsan (JGS) extract on anti-oxidant, anti-inflammatory activities in RAW 264.7 cells and on factors related with fracture healing in skull fractured rat. Methods Experimental animals were divided into four groups: normal group without any treatment (Normal), contral group were treated orally with distilled water (Control), Experimental group were treated orally with JGS at a concentration of 200 mg/kg/day (JGS 200) and Experimental group were treated orally with JGS at a concentration of 200 mg/kg/day (JGS 400). Rats in each group except the normal group were induced fractures in the skull. The 1,1-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical scavenging activity were measured to evaluate antioxidant activity. The production of nitric oxide (NO), $interleukin-1{\beta}$ ($IL-1{\beta}$), interleukin-6 (IL-6) and tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) in the RAW 264.7 cells were measured to evaluate anti-inflammatory activity. The production of osteocalcin calcitonin, carboxy-terminal telepeptides of type II collagen (CTX II), transforming growth $factor-{\beta}$ ($TGF-{\beta}$), bone morphogenetic protein-2 (BMP-2), Insulin and alkaline phosphatase (ALP) in serum of rats were measured to evaluate the effects of fracture healing at 0, 2, 4, and 6th week. X-rays were taken every 3 week from 0 to 6th week to evaluate fracture healing effect. Results 1. No cytotoxicity was observed. 2. DPPH and ABTS radical scavenging activity were increased in a concentration dependent manner, indicating anti-oxidant effect. 3. NO, $IL-1{\beta}$, IL-6, and $TNF-{\alpha}$ were not significantly changed, indicating no anti-inflammatory effect. 4. Osteocalcin, Calcitonin, $TGF-{\beta}$ and ALP were significantly increased in the experimental groups. 5. CTX II, insulin were significantly decreased in the expermental groups. 6. Radiologic examination showed that union of fracture was promoted. Conclusions From above results, JGS showed significant results in factors related with fracture healing and radiologic examination. Threfore, JGS is expected to be effective in the treatment of fracture.

Ginger (Zingiber officinale Roscoe) has been used as a raw material in many traditional preparations since the ancient time. As a component of traditional health products, Ginger is known to be effective as appetite enhancer, anticold and anti-inflammation. This study was performed to investigate the immunomodulative effects of Ginger in mouse, using in vitro and ex vivo experiments. In vitro experiment, the mice splenocytes proliferation and three kinds of cytokines (IL-1 $\beta$, IL-6, and TNF-$\alpha$) prodution by peritoneal macrophages cultured with ethanol and water extracts of Ginger were used to indicate the immunomodulative effect. In order to elucidate the immunomodulative effects of Ginger ex vivo, water extract of Ginger was orally administrated into mice, and isolated splencytes and macrophages were used as experimental model. Ex vivo experiment, six to seven week old mice were fed ad libitum on a chow diet, and water extract of finger was orally administrated every other day for four weeks at two different concentractions (50 and 500 mg/kg B.W./day). In vitro study, the splenocytes proliferation was increased when water extract was supplemented in the range of 50-500 $\mu$l/ml concentration. In case of cytokines production, IL-1 $\beta$, IL-6 and TNF-$\alpha$ released by activated peritoneal macrophages were augmented by the supplementation of water extract of the Ginger. Ex vivo experiment, the highest proliferation of splenocytes and production of cytokines by activated peritoneal macrophages were seen in the mice orally administrated at the concentration of 500 mg/kg B.W./day. In conclusion, this study suggests that Ginger extracts may enhance the immune function by regulating the splenocytes proliferation and enhancing the cytokine prodution capacity by activated macrophages in mice.

Objective : The purpose of this study is to investigate the immunological effect of Ramulus Cinnamomum aqua-acupuncture on the cellular immune response in mice with LPS induced arthritis. Methods : All the BALB/C mice used in this study were bred and maintaned in our pathogen-free mouse colony and were 6wk of age at the start of the experiment. The experimental model of arthritis was induced by injeciton of 300${\mu}g$/kg LPS in mice knee joint. Ramulus Cinnamomum aqua-acupuncture was injected into Yangnungchon(Gb34) of mice 2daily for 14days. Immunohistochemical analysis was carried out to assess CD4+, CD8+, CD11b, IL-$1{\beta}$, IL-2R and CD106 expression in common iliac lymph nodes and synovial menbrane after stimulation with Ramulus Cinnamomum. Electron microscopy was carried out to assess change of synovial membrane. Ramulus Cinnamomum aqua-acupuncture stimulation group was compared to control group and non stimutated with aqua-acupuncture. Resutts : At day 14 post arthritis onset, Immunohistological studies using monoclonal antibodies showed that Ramulus Cinnamomum aqua-acupuncture goup had decreased expression of CD4+, CD8+, CD11b, IL-$1{\beta}$, IL-2R and CD106 at common illiac lymph nodes and synovial membrane compared with control group. Conclusions : Ramulus Cinnamomum aqua-acupuncture stimulation inhibited the development of cellular immunity to LPS-induced arthritis in mice. Thus, aqua-acupuncture stimulation may have preventive effects on autoimmune inflammatory joint diseases. The effects of AA on immune function and disease activity in patients with RA warrant further investigation.

The aim of this study is to compare the anti-inflammatory and immunological activity of different parts (bone, meat, and rind) of Yeonsan Ogye (YO). In order to evaluate cytotoxicity, MTT assay was performed. We investigated the production of nitric oxide (NO) and pro-inflammatory cytokines, such as IL-$1{\beta}$, IL-6, and TNF-${\alpha}$, in LPS-induced RAW264.7 cells. All parts of the YO showed no toxicity at concentrations of 1, 10, and $100{\mu}g/m{\ell}$. Rooster's bone, hen's bone, and rind decreased the production of NO. And rooster's bone, meat, and hen's bone also attenuated TNF-${\alpha}$ production in LPS-induced RAW 264.7 cells. In addition, all parts of the YO decreased IL-$1{\beta}$ and IL-6 production in LPS-induced RAW264.7 cells, whereas they all increased IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ production in normal RAW264.7 cells. Rooster exhibited higher immune activation and inhibitory activity on inflammation than a hen, and among different parts of the YO, bone showed the highest activity. Our results demonstrated and compared the anti-inflammatory and immunological activity of different parts of the YO. These results suggest that YO may be developed as a raw material for new health supplement food and medicine to attenuate various symptoms related to inflammation and immunity.

The Angelicae dahuricae radix (ADR) has been used a traditional medicine to treat acne, erythema, headache, toothache, sinusitis, colds, and flu in Korea, Japan and China. Here, we report the effect of ADR on compound 48/80-induced ear-swelling and the phorbol myristate acetate (PMA) plus calcium ionophore A23187-induced inflammatory cytokine secretion in the human mast cell line, HMC-1. ADR dose-dependently inhibited the ear-swelling response induced by intradermal injection of compound 48/80, In vitro model, PMA plus A23187 significantly increased interleukin $(IL)-1{\beta}$, IL-8, granulocyte macrophage colony stimulating factor (GM-CSF), and tumor necrosis factor $(TNF)-{\alpha}$ secretion compared with media control. We also show that the increased cytokines $IL-1{\beta}$, IL-8, GM-CSF, and $TNF-{\alpha}$ level was significantly inhibited by treatment of ADR. In addition, ADR partially blocked PMA plus A23187-induced extracelluar signal-regulated kinases phosphorylation. These results suggest that ADR might explain its beneficial effect in the treatment of mast cell-mediated inflammatory diseases.
