Onchungeum(OCE), a herbal formula, has been used for treatment of anemia, discharging blood and skin diseases. In the previous study, we investigated the anti-cancer effect of OCE by G1 arrest of the cell cycle in human hepatocarcinoma cells, Hep3B cells. In this study, it was examined that the difference of anti-proliferative mechanisms by change in the ratio of OCE composition (OCE I) in Hep3B cells. Treatment of OCE I exhibited a relatively strong anti-proliferative activity and caused various morphological changes such as membrane shrinkage and cell floating. In addition, OCE-I arrests the cell cycle at G1 phase, which was associated with the down-regulation of cyclin D1 and Cdk6 expressions. The G1 arrest was also associated with the induction of Cdk inhibitors p27 and p21. Moreover, both p21 and p27 were detected by immunoprecipitation with anti-Cdk4 and anti-Cdk2 antibodies in OCE I-treated cells but in case of OCE, p21 did not make any complexes with Cdk4 and Cdk2. These results suggest that the change in the ratio of OCE composition might induce different mechanisms in anti-cancer efficacy of OCE, which may confer characteristic principles in oriental medical formula.

Although the grasshopper Oxya chinensis sinuosa has long been used as food in Korea, there is little data on its functional effects. In this study, we investigated the anti-inflammatory effect of O. c. sinuosa ethanol extract (OCE) in RAW 264.7 mouse macrophage cells treated with lipopolysaccharide (LPS) for induction of inflammation. First, we determined that there is no cytotoxicity at $2,000{\mu}g/ml$ or less of OCE in RAW 264.7 cells. To evaluate the anti-inflammatory effects of OCE, we investigated expression levels of pro-inflammatory cytokines such as tumor necrosis factor (TNF)-${\alpha}$ and interleukin (IL)-6, and pro-inflammatory enzymes such as inducible nitric oxide synthase (iNOS) and cyclo-oxygenase-2 (COX-2) in LPS-induced RAW 264.7 cells. In addition, we examined whether OCE could inhibit translocation of NF-${\kappa}B$ p65 into the nucleus in LPS induced RAW 264.7 cells. As a result, we found that the mRNA and protein levels of TNF-${\alpha}$ and IL-6 decreased in LPS-induced RAW 264.7 cells after treatment with OCE in a dose-dependent manner. In addition, we confirmed a $2,000{\mu}g/ml$ concentration of OCE inhibited translocation of NF-${\kappa}B$ p65 by immunnostaining and Western blot analysis, and a decrease in the protein expression levels of iNOS and COX-2. Accordingly, we suppose that OCE has an anti-inflammatory effect through down-regulation of TNF-${\alpha}$, IL-6, iNOS, and COX-2 related to ${\kappa}B$ p65 inflammatory signaling pathways.

Objectives: The objective of this study was to evaluate the effects of cytotoxicity, skin regeneration, anti-wrinkle, whitening and skin moisturizing of Oncheongeum (OCE).Methods: The cytotoxicity of OCE lyophilized aqueous extracts (yield=13.82%) was observed against human normal fibroblast cells and B16/F10 murine melanoma cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium Bromide (MTT) assay, and skin regeneration and anti-wrinkle effects were also evaluated through the assay of collagen type I synthesis compared to the transformation of the growth factor (TGF)-β1, hyaluronidase, collagenase and matrix metalloproteinase (MMP)-1 inhibitory assays compared to oleanolic acid (OA), and elastase inhibitory effects compared to phosphoramidon disodium salt (PP). In addition, OCE’s whitening effects were measured by a tyrosinase inhibitory assay and melanin formation test in B16/F10 murine melanoma cells compared to arbutin, and skin moisturizing effects were observed through a mouse skin water content test, respectively. Results: No OCE treatment-related cytotoxic effects appeared on human normal fibroblasts and B16/F10 murine melanoma cells. OCE concentration-dependently increased the collagen Type I synthesis on human normal fibroblast cells, and also effectively inhibited hyaluronidase, elastase, collagenase and MMP-1 activities. In addition, OCE inhibited melanin production of B16/F10 murine melanoma cells and activity of tyrosinase. And significant and dose-dependent increases of skin water content were detected in OCE-treated mouse skin compared to vehicle control skins. Conclusions: OCE showed favorable and sufficient effects in skin regeneration, anti-wrinkle, whitening and skin moisturizing in this experiment. But more detail mechanisms and studies on the skin protective efficiency of in vivo are needed with the screening of active biological compounds in individual OCE herbs.

The purpose of this study is to provide the basic data to measuring proper compensation for the homemakers. For this purpose, the value of household work is measured by variables and methods: overall substitute(OSE), specialised substitute (SSE), opportunity cost(OCE), reservation wage(RWE), subjective evaluation(SE). The Main Results are as follows: 1. The values by OSE, SSE, OCE, RWE and SE are respectively 497, 996, 676, 847, 616, 683, 707, 601 and 540, 366 won. 2. The values of homemakers are calculated individually by her demographic characteristics. 3, The values by SSE and OSE are increased in the order of type I.IV.III.II which are divided by the number of family member and age of homemaker.
