Bojungikgitang is the water extracts prepared from Ginseng Radix, Astragali Radix, Angelicae gigantis Radix, Astractylodis Rhizoma alba, Aurantii nobilis Pericarpium, Glycyrrhizae Radix, Bupleuri Radix, Cimicifugae Rhizoma, which has been used for the treatment of indigestion, and immunological disease in oriental countries. In this study, the effects of Bojungikgitang on the productions of nitiric oxide (NO) and prostaglandin $E_2\;(PGE_2)$, and the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were examined using RAW 264.7 macrophages activated with $interferon-{\gamma}\;(IFN-{\gamma})$ plus lipopolysaccharide (LPS). Bojungikgitang (10-400 ${\mu}$g/ml) per se had no cytotoxic effect in unstimulated macrophages, but this compound dose-dependently reduced the release of NO and $PGE_2$ caused by stimulation of $LPS/IFN-{\gamma}$. The levels of iNOS and COX-2 protein were markedly suppressed by the treatment with Bojungikgitang in a concentration dependent manner. Moreover, Bojungikgitang also attenuated the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (1L)-1${\beta}$ and IL-6 in LPS-stimulated RAW 264.7 macrophages. These results suggest that Bojungikgitang decreases the NO and $PGE_2$ production in macrophages by inhibiting iNOS and COX-2 expression and these properties may contribute to the anti-inflammatory activity of Bojungikgitang.

Objectives : The purpose of this study is to investigate the effects of Pyrrosiae Herba herbal-acupuncture(PH-HA) at $KI_{10}$(Umgok) on nephritis induced by lipopolysaccharide(LPS) in rats. Methods : Rats were assigned to four groups: normal, LPS, saline and PH-HA. Rats in the saline and PH-HA groups were treated with saline injection and PH-HA respectively at $KI_{10}$, three times over the period of one week. All animals, except those in the normal group, were injected intra-peritoneally with LPS to induce nephritis. WBC, in blood, tumor necrosis factor alpha(TNF-${\alpha}$), cytokine-induced neutrophil chemoattractant 1(CINC-1), blood urea nitrogen(BUN), creatinine in serum, urinal volume, total protein creatinine in urine, and renal myeloperoxidase (MPO) were analyzed. Results : 1. PH-HA group showed significantly reduced levels of serum BUN, serum creatinine, TNF-${\alpha}$, and CINC-1 compared to the LPS group. Furthermore, a significant increase in urine output and more significant decreases in total protein in urine and MPO in renal tissue were observed in the PH-HA group when compared to the LPS group. 2. The PH-HA group showed significantly reduced levels of serum creatinine and renal MPO, and a more significant increase in urine output compared to the saline group. Conclusions : According to these results, it is postulated that PH-HA at $KI_{10}$ has anti-inflammatory and renal-protective effects on LPS-induced nephritis in rats, and both acupoint $KI_{10}$ and the herb Pyrrosiae Herba made contributions to these effects. Further studies on the interaction between acupoint $KI_{10}$ and the herb Pyrrosiae Herba may be needed.

Objectives : We observed the possibilities that blue honeysuckle has favorable analgesic or refinement effects on the Primary dysmenorrhea (PD) in rats. Methods : Estradiol benzoate and oxytocin were used to induce the PD rat model. And Blue honeysuckle concentration lyophilized powders (BH) 500, 250 and 125 mg/kg and 500 mg/kg of Lonicerae Flos aqueous extract lyophilized powders (LF) were orally administered, once a day for 10 days at 30 min after each estradiol benzoate treatment. Then the changes on the body weights and gains during experimental periods, abdominal writhing response for analgesic activities, uterine weights, uterus lipid peroxidation, antioxidant defense system - glutathione contents, superoxide dismutase and catalase activities, NF-κB and COX-2 mRNA expressions were monitored with uterus histopathology including immunohistochemistry for tumor necrosis factor (TNF)-α and inducible nitric oxide synthase (iNOS).. Results : Inflammatory and oxidative stress mediated PD signs were favorably and dose-dependently inhibited by 10 days continuous oral administration of three different dosages of BH - 500, 250 and 125 mg/kg as comparable to those of indomethacin(IND) 5 mg/kg treated rats in BH 500 mg/kg administered PD rats, and similar to those of LF 500 mg/kg in BH 125 mg/kg, at least in a condition of the present PD rat model. Conclusions : The results suggest that BH has favorable analgesic and refinement activities on the estradiol benzoate and oxytocin treatment-induced PD signs through anti-inflammatory and antioxidative potentials.

BACKGROUND/OBJECTIVES: Stromal cell-derived growth factor 1 (SDF-1), also known as chemokine ligand 12, and chemokine receptor type 4 are involved in cancer cell migration. Compound K (CK), a metabolite of protopanaxadiol-type ginsenoside by gut microbiota, is reported to have therapeutic potential in cancer therapy. However, the inhibitory effect of CK on SDF-1 pathway-induced migration of glioma has not yet been established. MATERIALS/METHODS: Cytotoxicity of CK in C6 glioma cells was determined using an EZ-Cytox cell viability assay kit. Cell migration was tested using the wound healing and Boyden chamber assay. Phosphorylation levels of protein kinase C $(PKC){\alpha}$ and extracellular signal-regulated kinase (ERK) were measured by western blot assay, and matrix metallopeptidases (MMP) were measured by gelatin-zymography analysis. RESULTS: CK significantly reduced the phosphorylation of $PKC{\alpha}$ and ERK1/2, expression of MMP9 and MMP2, and inhibited the migration of C6 glioma cells under SDF-1-stimulated conditions. CONCLUSIONS: CK is a cell migration inhibitor that inhibits C6 glioma cell migration by regulating its downstream signaling molecules including $PKC{\alpha}$, ERK1/2, and MMPs.

In order to investigate the biological effects of conformational changes in the folding state of bovine ${\alpha}$-lactalbumin (${\alpha}$-La), the protein was prepared and classified as apo form, microbial transglutaminase (MTGase) added form, or bovine ${\alpha}$-La made lethal to tumor cell (BAMLET) form. Apo ${\alpha}$-La form showed weaker cancer cell inhibitory activity (apoptosis) than native ${\alpha}$-La, which suggests that the metal ion-like $Ca^{2+}$ had a positive effect, whereas BAMLET form showed strong cancer cell apoptotic activity. The BAMLET form seemed to be a molten globule structure that increased hydrophobicity. MTGase added to apo ${\alpha}$-La polymer showed similar anti-cancer activity as native ${\alpha}$-La, and it was well hydrolyzed by digestive enzymes. NMR results showed that BAMLET interacted with oleic acid and produced a complex.

Objective : The aim of this study was to evaluate the efficacy of Gagamchunggan-tang on anti-inflammation reaction with lipopolysaccharide (LPS)-induced HepG2 cell. Method : We examined the effects of the Gagamchunggan-tang, a traditional drug for liver inflammation, on the process of lipopolysaccharide(LPS)-induced nuclear factor-${\kappa}Bp65(NF-{\kappa}Bp65)$ activation in HepG2 cell. SDS-PAGE, Western blotting, Immunofluorescence staining were studied. Results : Immunoblot analysis showed that the level of nucleic $NF-{\kappa}Bp65$ was rapidly up-regulated and cytosolic inhibitory $I-{\kappa}B{\alpha}$ was down-regulated by LPS challenge. While Gagamchunggan-tang inhibited an increase of $NF-{\kappa}Bp65$ and degradation of $I-{\kappa}B{\alpha}$ in HepG2 cell. Besides LPS-induced expression of a group of genes, such as tumor necrosis factor-${\alpha}(TNF-{\alpha})$, inducible nitric oxide synthase(iNOS) and cyclooxygenase-2 (COX-2), are repressed by Gagamchunggan-tang. It may be concluded that Gagamchunggan-tang attenuates the progress of LPS-induced inflammation by reduction of $NF-{\kappa}Bp65$ activation. Conclusion : The Gagamchunggan-tang would be useful as a therapeutic agent for endotoxin-induced liver disease.

Betulinic acid (BA), a natural pentacyclic triterpene found in many medicinal plants is known to have various biological activity including tumor suppression and anti-inflammatory effects. In this study, the cell-death induction effect of BA was investigated in BV-2 microglia cells. BA was cytotoxic to BV-2 cells with $IC_{50}$ of approximately $2.0{\mu}M$. Treatment of BA resulted in a dose-dependent chromosomal DNA degradation, suggesting that these cells underwent apoptosis. Flow cytometric analysis further confirmed that BA-treated BV-2 cells showed hypodiploid DNA content. BA treatment triggered apoptosis by decreasing Bcl-2 levels, activation of capase-3 protease and cleavage of PARP. In addition, BA treatment induced the accumulation of p62 and the increase in conversion of LC3-I to LC3-II, which are important autophagic flux monitoring markers. The increase in LC3-II indicates that BA treatment induced autophagosome formation, however, accumulation of p62 represents that the downstream autophagy pathway is blocked. It is demonstrated that BA induced cell death of BV-2 cells by inducing apoptosis and inhibiting autophagic flux. These data may provide important new information towards understanding the mechanisms by which BA induce cell death in microglia BV-2 cells.

In the present study, we investigated anti-inflammatory activity of artemisinic acid in HaCaT cells and RAW264.7 cells. Artemisinic acid showed inhibitory activity on macrophage-derived chemokines (MDC) expression, a factor related with atopic dermatitis (AD), in interferon (IFN)-${\gamma}$ and tumor necrosis factor (TNF)-${\alpha}$-stimulated HaCaT cells. In the study on action mechanism, pretreated artemisinic acid reduced the phosphorylation of STAT1 and p38 and the degradation of $I{\kappa}B$ by IFN-${\gamma}$ and TNF-${\alpha}$ stimulations. However, artemisinic acid didn't show the inhibitory activity on LPS-induced inflammatory mediators (NO, $PGE_2$, IL-6) in RAW264.7 cell. These results indicate that artemisinic acid inhibits IFN-${\gamma}$ and TNF-${\alpha}$-induced MDC expression through inhibition of signal factors, STAT1, NF-${\kappa}B$, and p38, in HaCaT keratinocytes.
