  • La demarche et l'objet de cette recherche sont d'analyser, psychiquement, biologiquement, les marques de l'intersexualite presentent en Occident et les elements intersexuels, binaires dans le vetement, et egalement de comprendre l'ambiguite ou encore la fusion des identites sexuees. qui presente symboliquement a travers le vetement, dans la societe moderne. Malgre tous les points communs et differents, la base fondamentale dans les theories de I'Occident est que tout individu est psychiquement, biologiquement en quelque sorte un intersexuel qui s'ignore, avec des variations selon l'individu. En definitive, les compositions doubles des elements dans le vetement occidental montraient emblematiquement nos qualites doubles, masculins et feminins, et les trois elements semblent primordiaux pour l'elucidation de la predisposition du porteur : la couleur du tissu, sa texture et la forme du vetement. La mode d'aujourd'hui bascule entre masculin et feminin. Cette fusion de la mode semble le reflet d'une tendance intersexuelle et d'une fusion du genre.

  • Proinflamamtory mediators such as prostaglandins (PGs), cyclooxygenase-2 (COX-2), and inducible nitric oxide synthase (iNOS) are known to be key mediators in pathogenesis of inflammatory diseases. Capsaicin, the major ingredient of hot pepper, is considered to elicit anti-inflammatory property. In this study, the effect of capsaicin on the prostaglandin E$_2$(PGE$_2$) production was investigated in murine peritoneal macrophages.(omitted)

  • The aim of this study is to elucidate the anti-inflammatory activities of chopi (Zanthoxylum piperitum A.P. DC.) essential oil. Essential oil (EO) of chopi was extracted by steam distillation method, and its major constituents were limonene and geranyl acetate. Chopi-EO decreased approximately 38% of nitrite production, as compared to the lipopolysaccharde (LPS)-induced nitrite production. However, chopi-EO and its components did not quench nitric oxide (NO) chemically in cellfree system, and markedly inhibited approximately 40.4% of inducible nitric oxide synthase (iNOS) mRNA transcription. In addition, the inhibition of E-selectin gene transcription by chopi-EO caused the suppression of cellular adhesion. These results suggest that chopi-EO may exert potential anti-immunological inflammatory activity.

  • Human placental extract (HPE), which is prepared from the placenta of healthy pregnant females, has been widely used in clinical field. HPE is known to possess anti-inflammatory, anti-viral, anti-oxidative, anti-mutagenic, and analgesic properties. In this study, the effect of HPE against lipopolysaccharide (LPS)-induced inflammation was investigated. From the present results, HPE was shown to suppress prostaglandin E2 synthesis (PGE2) and nitric oxide (NO) production by inhibition on the LPS-stimulated enhancement of the cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) expressions in mouse BV2 microglial cells. These results suggest that HPE may offer a valuable mean of therapy for the treatment of brain inflammatory diseases by attenuating LPS-induced PGE2 and NO production.

  • The purpose of this paper is to investigate potential anti-inflammatory and anti-oxidant effects of Tenebrio molitor. Macrophage cell response by outside stimulation leads expression of pro-inflammatory cytokines, such as tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), interleukin-6 (IL-6), $interleukin-1{\beta}$ ($IL-1{\beta}$), and trigger expression of genes which are affected by inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), resulting in formation of inflammatory factors like nitric oxide (NO) and Prostaglandin $E_2$ (PGE2). Cell viability was determined by MTT assay. In order to investigate anti-inflammatory agents, the inhibitory effects on the production of lipopolysaccharide (LPS)-induced NO in RAW 264.7 cells were examined. T. Molitor significantly decreased the production of NO in a dose-dependent manner, and also reduced the expression of iNOS, a COX-2 protein. As a result, the levels of protein such as $PGE_2$, iNOS, COX-2 and MARKs were significantly reduced compared to non-treated group in T. Molitor water extract (TDW) treated group. Also, antioxidant effect of T. Molitor were investigated using DPPH, ABTS+ and superoxide anion radical scavenging activity tests in cell-free system. Antioxidant activity of T. molitor was found low in the DPPH radical scavenging test while high in the ABTS+ and superoxide anion radical scavenging activity tests. These results show that TDW could be an effective anti-pro-inflammatory and anti-oxidant agent.

  • This study was conducted to evaluate the efficacy of Cheongawongagam on osteoporosis rat. A total of 35 rats were divided into seven groups; Normal control(SD-Nr), experimental control group(OVX-CTL), positive control group(OVX-17β-E2) and herb extracts group[Eucommia ulmoides(OVX-EU-E), Juglandis semen(OVX-JR-SE), Acanthopanax senticosus(OVX-AS-E) extract and Cheongawongagam extracts(OVX-JAEG-E)]. All control group, and herb extracts group were ovariectomized. After the 3 weeks recovery period, herb extract group were orally administered 200 mg / kg of the EU-E, JR-SE, AS-E and JAEG-E for 12 weeks. In the OVX-CTL, 17β-estradiol(E2) was administered subcutaneously on the back of the rats at a dose of 0.03 ug/sc. Their body weight, serum total cholesterol, triglyceride, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), Leukotriene B4 (LTB4), calcium (Ca), estradiol, osteocalcin, and deoxypyridinoline (DPD) concentration were measured. Also, we investigated mRNA expression of inflammatory cytokine, MMP-2, MMP-9, and bone tissue. As a result, total cholesterol was significantly decreased in the OVX-AS-E and OVX-JAEG-E. ALP was significantly increased and osteocalcin, DPD was significantly decreased in OVX-JAEG-E. The expression of inflammatory mediators (TNF-α, IL-1β, LTB4, COX-2, NOS-2), inflammatory cytokines IL-1β and MMP-9 mRNA were significantly decreased in OVX-JAEG-E. Histologic examination of the femur showed that bone mineral density, and bone mass were increased and bone marrow were decreased in the OVX-JAEG-E group. The above experiment shows that cheongawongagam extract were effective in the prevention and treatment of osteoporosis.

  • Mahaenggamsuk-tang (MHGS) has been widely used in Korea and China for the treatment of various diseases. MHGS was constituted the Ephedrea Herba, Armenicae Semen, Glycyrrhizae Radix and Gypsum Fibrosum. In this study, we have made three different solvents extract as MHGS water extract (MHGS-W), MHGS 50% EtOH extract (MHGS-50E), and MHGS 100% EtOH extract (MHGS-100E). The MHGS-W, MHGS-50E and MHGS-100E showed the discernible difference patterns on HPLC analysis. Furthermore, MHGS-50E and MHGS-100E significantly increased the DPPH and ABTS radical scavenging effects than MHGS-W. In addition, the MHGS-50E and MHGS-100E also inhibited significantly nitric oxide (NO) and prostaglandin E2 (PGE2) production, and inducible nitric oxide synthase (iNOS) cyclooxygenase-2 (COX-2) protein expression in RAW264.7. On the other hand, MHGS-50E and MHGS-W showed remarkable protection on the HT22 cell via heme oxygenase (HO)-1, but MHGS-100E did not show. The results of this study proved that MHGS-50E has greater potential therapeutic uses by exerting antioxidant, anti-inflammatory and neuroprotective effects compared to MHGS-100E, MHGS-W. Our study suggests that the different solvent might be affected the biological activities when make the traditional herbal medicines including MHGS.

  • The aim of this study was to evaluate an efficacy about activation on macrophage, using model that measured cell viability, nitric oxide (NO), iNOS (inducible nitric oxide synthase) expression and tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) on Raw 264.7 cells following treatment of Germanium-fortified Yeast in 0, 5, 10, 25, 50, 100, $200\;{\mu}g/ml$ and the same concentration of dried yeast without germanium. Cell viability (%) and NO produced in activated-macrophage were dose-dependant, a significant increase of the cell viability (132.5%) and NO in $10\;{\mu}g/ml$ (p < 0.05). Increase in iNOS level was in $10\;{\mu}g/ml$. $TNF-{\alpha}$ was produced dose-dependant, e.g. in activated-macrophage with a significant increase of the $TNF-{\alpha}$ in 5 and $10\;{\mu}g/ml$ (p < 0.05). Therefore, Germanium-fortified Yeast had an efficacy of NO mediated iNOS and $TNF-{\alpha}$ production by activated macrophage. This result showed that Germanium-fortified Yeast induced activation of cellular immunity, returned to normalcy on injured immune system and procured anticancer system by activation of macrophage, which was important in immune and anticancer function.

  • In this study, we investigated the anti-inflammatory effects of Lactobacillus rhamnosus fermented black garlic (FBG) in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. FBG did not show cytotoxicity in RAW 264.7 cells at concentrations less than $800{\mu}g/mL$, and cell viability increased with FBG concentration. Nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) production as well as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$) and IL-6 formation decreased in an FBG concentration-dependent manner, in LPS-induced RAW 264.7 cells. Furthermore, activation of LPS-inducible nitric synthase (iNOS), cyclooxygenase-2 (COX-2), nuclear factor kappa B (NF-${\kappa}B$), and inhibitory kappa B ($I{\kappa}B$) protein expression was effectively inhibited by FBG treatment in LPS-induced RAW 264.7 cells. In contrast, heme oxygenase-1 (HO-1) protein expression significantly increased. These results indicate that the anti-inflammatory activity of FBG was due to activation of NF-${\kappa}B$, inhibition of cytokine production, and expression of iNOS and COX-2. From these results, we expect that FBG could contribute to the prevention and improvement of inflammatory disease.
