This study was performed to evaluate anti-thrombotic activities and anti-inflammatory effects of ChungyeolHaedogHwaeoTang water extract(CHHT). The results were summarized as follows. In experiment of anti-thrombotic effect; 1. CHHT inhibited human platelet aggregation induced by ADP and epinephrine as compared with the control group, and inhibited pulmonary embolism induced by collagen and epinephrine (inhibitory rate is 37.5%). 2. CHHT increased platelet number significantly, and also CHHT shortened PT and APTT significantly as compared with the control group in thrombus model induced by dextran. In experiment of anti-inflammatory effect; 3. CHHT inhibited $IL-1{\beta}$, IL-6, TNF-${\alpha}$, COX-2 and NOS-II mRNA expression as compared with the control group in a concentration-dependent degree, and inhibited NO production significantly at 50, 100 ${\mu}g/ml$, and also inhibited ROS production in a concentration-dependent degree as compared with the control of group in RAW 264.7 cell line. 4. CHHT inhibited $IL-1{\beta}$, IL-6 and TNF-${\alpha}$ production significantly in serum of acute inflammation-induced mice, and decreased $IL-1{\beta}$, IL-6 and TNF-${\alpha}$ production in spleen tissue, and also decreased $IL-1{\beta}$, and IL-6 production in liver tissue, but increased TNF-${\alpha}$ production in liver tissue of acute inflammation-induced Balb/c mice. 5. CHHT increased survival rate from the 3rd day in ICR mice with lethal endotoxemia induced by LPS. These results suggest that CHHT can be useful in treating diverse female diseases caused by thrombosis and inflammation such as menstrual pain, menstrual disorder, leukorrhea, vaginitis, cervicitis, pelvic inflammatory disease and so on.

Objectives : This study was an analysis of the anti-inflammatory, anti-oxidative and skin whitening properties of Gamioncheong-decoctione(GMOCD) extract. Methods : GMOCD(96 g) and 2 L of distilled water were heated at $100^{\circ}C$ for four hours and then concentrated, frozen, freeze-dried, dissolved in distilled water and filtered. The following analysis was completed: cell cytotoxic effect using MTT assay, oxidative products of NO by griess assay, concentration of prostaglandin $E_2(PGE_2)$ by commercially competitive enzyme immunoassay, and cytokines($IL-1{\beta}$, IL-6 and TNF-${\alpha}$) by Bio-Plex$^{(R)}$ Suspension Array System's Bio-Plex Pro$^{TM}$ mouse cytokine, chemokine, and growth factor assay. Anti-oxidative effect was measured using the DPPH method and skin whitening effect using tyrosinase inhibition assay. Results : GMOCD water-extract did not show any toxicity at all doses and cell viability was more than 90 % at all doses. GMOCD water-extract significantly inhibited NO production at doses of 100, 200, $400{\mu}g/ml$, significantly inhibited $PGE_2$ production at doses of 200 and $400{\mu}g/ml$ and reduced the LPS-induced IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ production in a dose-dependent manner. $IL-1{\beta}$ production was significantly reduced at a dose of $400{\mu}g/ml$ and IL-6 production was significantly reduced at doses of 200 and $400{\mu}g/ml$. DPPH free radical scavenging capability had a skin whitening effect rate of more than 50%. Tyrosinase inhibition activity was apparent in a dose-dependent manner. Conclusions : This study suggests that GMOCD water-extract suppressed NO and $PGE_2$ production and inhibited cytokines($IL-1{\beta}$, IL-6 and TNF-${\alpha}$). GMOCD also improved DPPH free radical scavenging capability. GMOCD water-extract increased tyrosinase inhibitory activity in a dose-dependent manner but this was not a statistically significant result.

Thiourea and vinyl sulfoxide derivatives were designed based on the structures of sulforaphane and gallic acid, prepared and tested for HO-1 inducing activity as a measure of Nrf2 activation, and inhibitory effect on NO production as a measure of anti-inflammatory activity. Both series of compounds showed moderate activity on HO-1 induction, and no inhibitory effect on NO production. Interestingly the thiourea compound 6d showed better HO-1 induction (71% SFN) than the corresponding isothiocyanate compound 6a (55% SFN). Overall, it seemed that more efficient electrophile is needed to get more effective Nrf2 activator.

This study was conducted to evaluate the effect of Grateloupia elliptica, a seaweed native to Jeju Island, Korea, on the prevention of hair loss. When immortalized rat vibrissa dermal papilla cells were treated with extract of G. elliptica, the proliferation of dermal papilla cells significantly increased. In addition, the G. elliptica extract significantly inhibited the activity of $5{\alpha}$-reductase, which converts testosterone to dihydrotestosterone (DHT), a main cause of androgenetic alopecia. On the other hand, the G. elliptica extract promoted $PGE_2$ production in HaCaT cells in a dose-dependent manner. The G. elliptica extract exhibited particularly high inhibitory effect on LPS-stimulated IL-12, IL-6, and TNF-${\alpha}$ production in lipopolysaccharide (LPS)-stimulated bone marrow-derived dendritic cells. The G. elliptica extract also showed inhibitory activity against Pityrosporum ovale, a main cause of dandruff. These results suggest that G. elliptica extract has the potential to treat alopecia via the proliferation of dermal papilla, $5{\alpha}$-reductase inhibition, increase of $PGE_2$ production, decrease of LPS-stimulated pro-inflammatory cytokines and inhibitory activity against Pityrosporum ovale.

Objective: To derive information on the efficacy of Sam-chul-kun-bi-tang (SKT), by evaluating its anti-inflammatory effect. SKT is a widely-used herbal formula in traditional Korean medicine. In man y studies, plant-derived anti-inflammatory efficacies have been investigated for their potential inhibitory effects on lipopolysaccharide (LPS)-stimulated macrophages. This study was performed to examine the anti-inflammatory effects of SKT extract on LPS-stimulated RAW 264.7 cells. Methods: The production of nitric oxide (NO), prostaglandin $(PG)E_2$, tumor necrosis factor (TNF)-$\alpha$ and interleukin (IL)-6 were examined in a macrophage cell line, RAW 264.7 cells, in the presence of SKT. RAW 264.7 cells were incubated with LPS 1 ${\mu}g/mL$ and SKT for 18 hrs. The anti-inflammatory activity of SKT was investigated by carrageenan-induced paw edema in rats. The paw volume was measured at 2 and 4 hrs following carrageenan-induced paw edema in rats. Results: SKT showed inhibitory effect on $PGE_2$, TNF-$\alpha$ and IL-6 in LPS-stimulated RAW 264.7 cells. But SKT was not inhibitory effect on NO by LPS-stimulated RAW 264.7 cells. Administration of SKT (1 g/kg) also showed a reduction in carrageenan-induced paw edema on rats. Conclusion: These results suggest that SKT has anti-inflammatory activities in both in vitro and in vivo models.

Objectives : Bilobalide (BIL) is a predominant sesquiterpene trilactone constituent that accounts for a partial portion of the standardized Ginkgonis Folium extract, which has been widely used to treat a variety of neurological disorders involving cerebral ischemia and neurodegeneration. In this study, it was tested whether BIL exhibits anti-inflammatory activities on inflammation response, or not. Methods : To elucidate the molecular mechanisms of BIL on pharmacological and biochemical actions in inflammation, we examined the effect of BIL on pro-inflammatory mediators in lipopolysaccharide (LPS)-stimulated macrophages. The investigation was focused on how BIL affect on inflammation-related mediators including various signals such as nitric oxide (NO), prostaglandin $E_2$ ($PGE_2$), inducible NO synthase(iNOS), cyclooxygenase-2(COX-2), interleukin-6(IL-6), tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), mitogen-activated protein kinases(MAPKs) and nuclear factor kappa-light-chain-enhancer of activated B cells ($NF-{\kappa}B$) in LPS-stimulated RAW 264.7 cells. Results : We found that BIL inhibited LPS-induced NO, $PGE_2$, IL-6 and $TNF-{\alpha}$ productions as well as the expressions of iNOS and COX-2. Furthermore, BIL suppressed the LPS-induced phosphorylation for MAPK activation. Conclusions : These results suggest that BIL has inhibitory effects on LPS-induced $PGE_2$, NO, IL-6 and $TNF-{\alpha}$ production, as well as the expressions of iNOS and COX-2 in the murine macrophage. It seems that these inhibitory effects occur by blocking the phosphorylation of MAPKs for activation. Then, BIL suppressed the activation of nuclear factor $NF-{\kappa}B$ in nucleus. These observations suggest that BIL has anti-inflammatory effect by inhibiting.

Artemisiae Asiaticae Herba (AAH) has been used to remedy of symptoms such as bleeding, dysmenorrhea, eczema and itchy skin in Oriental Medicine. In this study, we investigated the protective effect of AAH on allergic response. The effect of AAH was analyzed by ELISA and RT-PCR in RBL-2H3 cells. We investigated cell viability, ${\beta}$-hexosaminidase and histamine as markers of degranulation, production of IL-4 and TNF-${\alpha}$, and gene expression of HDC2, cytokines and $Fc{\varepsilon}RI$ ${\alpha}{\beta}{\gamma}$ subunit. We found that AAH suppressed ${\beta}$-hexosaminidase and histamine release, the production of IL-4 and TNF-${\alpha}$ in RBL-2H3 by the anti-DNP IgE plus DNP-HSA stimulation. AAH also significantly decreased cytokine mRNA expressions, such as IL-$1{\beta}$, IL-2, IL-3, IL-4, IL-5, IL-6, IL-12, IL-13, TNF-${\alpha}$, and GM-CSF, and increased cytokine mRNA expressions of IL-10 in RBL-2H3. In addition, AAH suppressed mRNA expression of $Fc{\varepsilon}RI$ ${\alpha}{\beta}{\gamma}$ subunit on cell surface. Our results indicate that AAH protects against allergic response and exerts an anti-inflammatory effect through the inhibition of degranulation and production of cytokines and expression of $Fc{\varepsilon}RI$ ${\alpha}{\beta}{\gamma}$ subunit.

In the present study, we exarnined anti-allergic effect of SGBHB in cultured B cells. B cells were prepared from isolated murine splenocytes and activated by co-treatment of anti-CD40 monoclonal antibody and recombinant IL-4 allergens. Anti-allergic effects of SGBHB in activated B cells were determined by measuring B cell surface activated molecules (CD23+ and CD11a+), and expression levels of IL-$1{\beta}$, IL-6, IL-10, TNF-$\alpha$, IgE, and HRF. The major findings are summarized as follows. 1. SGBHB treatment did not produce significant cytotoxic effects on mouse lung fibroblast cells. 2. SGBHB produced significant inhibitory effect on the expression of B cell surface activated molecules (CD23+ and CD11a) in activated B cells. 3. SGBHB treatment significantly inhibited expression levels of IL-$1{\beta}$, IL-6, and TNF-$\alpha$ mRNAs in activated B cells.IL-6 protein levels were significantly decreased by $100{\mu}g/m{\ell}$ of SGBHB treatrrient, and TNF-$\alpha$ protein levels were decreased compared to the control group, but statistically insignificant. 4. SGBHB treatment significantly increased IL-10 at both mRNA and protein levels in activated B cells. 5. SGBHB treatment significantly inhibited levels of IgE production. Thus, the present data suggest that SGBHB has an anti-allergic effect on activated B cells by controlling irnmune responses, and further implicates the possibility on clinical application as a therapeutic agent.

As part of our search for less toxic antimicrobial agents from natural resources. rutin was isolated from Sophora japonica and then hydrolyzed to quercetin. Antimicrobial activity of quercetin was tested in vitro against five kinds of gram positive and ten kinds of gram negative bacteria by serial broth dilution method. Among fifteen kinds of bacteria tested, the antimicrobial activity of quercetin was the most potent against Proteus vulgaris showing minimal inhibitory concentration(MIC) of 125 ${\mu}$g/ml. To investigate the effect of antimicrobial combinations of quercetin with four kinds of antibiotics (ampicillin, cefazolin, oxytetracycline and chloramphenicol). the fractional inhibitory concentration index (FICI) was determined by checkerboard assay for each strain. The antimicrobial combinations of quercetin with four kinds of antibiotics resulted in synergism in one instance, additive effect in four instances, but no antagonism was observed.
