Objective : This study was designed to investigate anti-cancer and whitening activities (LC). So it was investigated the effects of LC on proliferation rates of melanoma genetic profile by LC. Methods : The genetic profile for the effect of LC on human derived melanoma cell, SK-MEL-2, was measured using microarray technique, and the functional analysis on these genes were conducted. Total 441 genes were up-regulated and 830 genes down-regulated in cells treated with LC. Genes induced or suppressed by LC were all mainly concerned with basic signalling pathways, which are involved in cell growth, differentiation and migration. Especially, many genes, which are related in apoptosis and cell cycle arrest were up-regulated by treatment with LC, and genes related in cell cycle were down-regulated. Result : The network of total protein interactions were identified by using cytoscape program, and some key molecules, such as BCL2L1, SIN3A, SMAD2 and c-myc that can be used for elucidation of therapeutical mechanism of medicine in the future. Conclusion : These results suggest possibility of LC as addition drug and whitening cosmetics. In addition, it was also suggested that related mechanisms are involved in BCL2L1, SIN3A, SMAD2 and c-myc related signalling pathways.

In order to investigate the immunomodulational effects of Lonicerae Caulis et Folium, the author measured cytokines production(IL-10, IL-12(P35), IL12(P40), $IFN-{\gamma}$) in mice splenocytes. The results were obtained as follows : 1. The water extract of Lonicerae Caulis et Folium significantly enhanced the gene expression of IL-12(P35), IL-12(P40), but reduced the gene expression of IL-10, $IFN-{\gamma}$. 2. In water fraction and ethyl acetate fraction, the gene expression of IL-12(P35), $IFN-{\gamma}$ was significantly increased and that of IL-12(P40), IL-10 was decreased. The above results demonstrate that Lonicerae Caulis et Folium has enhancing immune activity by upregulation of these cytokines. Therefore, if we make the relationship between these cytokines(IL-10, IL-12, $IFN-{\gamma}$) besides IL-1, IL-4, IL-6, $TNF-{\alpha}$, IL-8, $TGF-{\beta}$ and so on which concerned the immunopotentiation, the immunopotentiational mechanism of Lonicerae Caulis et Folium will be shown clearly.

Objectives : Allergic contact dermatitis(ACD) is a type IV delayed hypersensitivity reaction that results from cumulative exposures and subsequent sensitization to an environmental chemical. Lonicerae Caulis(LC) can clear away heat and relieve toxin, disperse wind and heat, dredge the channel. The present study was designed to investigate the effects of LC on allergic contact dermatitis(ACD) induced by 2,4-dinitrochlorobenzene(DNCB) in mice. Methods : In this experiment, the effects of LC on changes in body weights, ear and dorsum skin thicknesses, ear weights, clinical aspects on the dorsum skin, histopathological changes, spleen/body ratio, cytokines were investigated. In addition, the effects on proliferations of splenocytes were also investigated in vitro and vivo study. Results : LC spread(SPR) group and LC spread and administered(SPR+ADM) group showed diminished ear thicknesses. In SPR+ADM group, ear weights were lowered significantly compared to contact dermatitis control(CTL) group. LC treatment diminished erythema, desquamation and keratosis which were induced by repeated painting of DNCB. In histopathological observation, spongiosis and edema were diminished in SPR and SPR+ADM group. In cytokines, SPR+ADM group were increased in IL-10, and SPR and SPR+ADM group were decreased in TNF-${\alpha}$ compared with control group. Conclusions : These data suggest that LC can decrease symptoms of ACD, then LC is useful to treat patient with ACD.

Objective ： Lonicera japonica contains anti complementary polysaccharides and polyphenolic compound. Among these polyphenolic substances, chlorogenic acid is the major active component of this plant. However, the immunological mechanisms for these activities, have not been elucidated, nor the active components. To clarify immunomodulatory effects of those we examined the relationship between the activity of CD8+ T cell-mediated lysis and the frequency of cytokine profiles in spleen, thymus (especially IFN-${\gamma}$, IL-4, GM-CSF etc.) expressing CD8+ T cells activated by IL-2. Methods : To study immunomodulatory effects ethyl acetate fraction from Lonicera japonica, chlorogenic acid on cytokine gene expression from spleen, thymus cells, RT-PCR was performed after quantitative normalization for each gene by a densitometry using ${\beta}$-actin gene expression. A modified standard $^{51}Cr$-release assay was used to measure cytotoxic activities of cytotoxic T cells. Spleen, thymus cells from NOD mice were stained with CD3, CD4, CD44, CD69 in staining buffer and analyzed by two color flow cytometry. Results : We showed that ethyl acetate fraction from Lonicera japonica in combination with IL-2 resulted in a significant enhancement of PCR products for IFN-${\gamma}$, IL-4, IL-10, GM-CSF, IL-6 and cytotoxtic CD8+ T cell proportion in spleen and thymus T cells in NOD mice. This suggests that IFN-${\gamma}$, IL-6 like IL-4 may be acting as a regulatory rather than proinflammatory cytokine. Conclusions : In conclusion, based on the results of the present study which showed that ethyl acetate fraction from Lonicera japonica and chlorogenic acid upregulating cytokine gene expression in spleen and thymus, we are tempted to speculate that some of the therapeutic efficacies such as anti-diabetic activity of Lonicera japonica are due to the immunomodulatory its ethylacetate fraction and chlorogenic acid.

This study aimed at examining the anti-inflammatory effects of Scutellariae Radix & Lonicerae Caulis water extract(SC). RAW 264.7 mouse macrophage cells were treated with $25{\sim}200{\mu}g/m{\ell}$ SC for 24 hours. Cell viability was then measured using MTT assays. The nitric oxide(NO) production and the creation of several cytokines in LPS-stimulated RAW 264.7 cells were investigated. SC inhibited significantly increasing the production of NO in LPS-induced RAW 264.7 cell at the density of 25, 50 and $200{\mu}g/m{\ell}$. SC inhibited significantly the TNF-${\alpha}$ of the RAW 264.7 cell induced by LPS at the density of $50{\mu}g/m{\ell}$. SC inhibited significantly the MIP-$1{\alpha}$ of the RAW 264.7 cell induced by LPS at the density of 25, 50 and $100{\mu}g/m{\ell}$. SC inhibited significantly the MIP-$1{\beta}$, MIP-2 at the density of 50, $100{\mu}g/m{\ell}$ in the RAW 264.7 cell increased by LPS, respectively. SC did not affect the production levels of VEGF in RAW 264.7 cell. As a result, SC significantly inhibited the inductions of MIP-$1{\alpha}$, MIP-$1{\beta}$, MIP-2 and NO in LPS-induced RAW 264.7 cell without causing the toxicity. These results signify that SC has anti-inflammatory effects on controlling the over inflammatory reaction on the RAW 264.7 cell.
