  • Cnidium officinale, a traditional herb, has diverse beneficial pharmacological activities, such as anti-inflammatory, antioxidant, anticancer, and antiangiogenesis effects. However, the cellular and molecular mechanisms of apoptosis by C. officinale are poorly defined. The present study investigated the proapoptotic effects of water, ethanol, and methanol extract of C. officinale (WECO, EECO, and MECO, respectively) in human leukemia U937 cells. The antiproliferative activity of EECO was higher than that of WECO and MECO. The antiproliferative effect of EECO treatment in U937 cells was associated with the induction of apoptotic cell death, including increased populations of annexin-V positive cells, the formation of apoptotic bodies, DNA fragmentation, and increased numbers of cells with a loss of mitochondrial membrane potential (MMP, Δψm). EECO-induced apoptotic cell death was associated with upregulation of death receptor 4 (DR4) and down-regulation of cellular inhibitor of apoptosis protein-1 (cIAP-1), Bcl-2, and total Bid. The EECO treatment also induced the proteolytic activation of caspases (-3, -8, and -9), and degradation of caspase-3 substrate proteins, such as poly(ADP-ribose) polymerase (PARP), β-catenin, and phospholipase C-γ1 (PLCγ1). In addition, the EECO treatment effectively activated the adenosine monophosphate-activated protein kinase (AMPK) signaling pathway. However, compound C, a specific inhibitor of AMPK, significantly reduced EECO-induced apoptosis. These results indicate that AMPK is a key regulator of apoptosis in response to EECO in human leukemia U937 cells.

  • Objectives: This study was performed to investigate the effects of Gagamsosokmyeong-tang(Jiajianxiaoxuming-tang) on the monosodium iodoacetate(MIA) induced early state osteoarthritis in rats. Methods: Osteoarthritis was induced by injection of MIA(0.25 mg) into knee joints of rats. Osteoarthritis rats were divided into control(n=8) and treated=8 group respectively, Control group was taken distilled water and treated group was taken extracts of Gagamsosokmyeong-tang(Jiajianxiaoxuming-tang) by orally for 20 days. Body weight was measured at 0, 5, 10, 15, 20 days after MIA injection. At the end of experiment, gross and histopathological examination on the articular cartilages of the knee joints were performed. Proteoglycan(PG) content of articular cartilages were analysed by safranine O staining method. The content of tumor necrosis $factor-{\alpha}(TNF-{\alpha})$, $interleukin-1{\beta}(IL-1{\beta})$ in synovial fluids were analysed by enzyme-inked inmunosorbent assay(ELISA) method. And also cycloxygenase-2(COX-2), matrix metalloproteinase 3(MMP-3), inducible nitric oxide synthase(iNOS), calpain immunochistochemical examination on the knee joints were performed. Results: PG content in articular cartilages of the treated group was significantly increased compared with control group. Histopathological osteoarthritic score of the treated group was significantly decreased compared with control group. $TNF-{\alpha}$ content in synovial fluids, expression of iNOS and calpain in synovial membrane of the treated group were significantly decreased compared with control group. But body weight, $1L-1{\beta}$ content in synovial fluids, expression of iNOS and MMP-3 of the treated group were not significantly changed compared with control group. Conclusions: On the basis of these results, we conclude that Gagamsosokmyeong-tang(Jiajianxiaoxuming-tang) has anti-arthritic effects on the MIA induced early stage osteoarthritis in rats.

  • Since the lips are a representative facial part that can express human attraction, aesthetic interest in them has always existed in human history. However, as lips age, they tend to form wrinkles, become thinner, and lose their volume. To counteract this phenomenon, medical procedures such as fillers or fat transplantation have been suggested. In this study, we verified that the one of main effective material complex of L G H&H L IPCERIN®, combination of cedrol, a sesquiterpene found in cedarwood, and three peptides (acetyl hexapeptide-8, acetyl tetrapeptide-9, and desamidocollagen) could ameliorate the photo-aging and reduce the wrinkles through in vitro experiments. The possibility of improving collagen and elastin expression in skin fibroblasts and reducing MMP expression under photoaging conditions was verified. In addition, it was confirmed that the amount of fat tissue in the lips can be increased by promoting adipose stem cell differentiation and increasing the amount of fat produced in the in vitro adipose stem cell differentiation experiment. Two weeks of human application tests confirmed that a combination of cedrol and peptides can improve the wrinkles, texture, elasticity, and volume of the lips. This study verified that the combination of cedrol and three peptides can be used as effective cosmetic materials to decrease the various signs of aging in the lips.

  • This study aimed to analyze the contents of rutin, procyanidin B3, quercetin, and kaempferol, known to have antioxidant, anti-inflammatory, and anti-carcinogenic effects, among the polyphenol types contained in grape pruning stem extracts (GPSE). It utilized grape stems discarded after harvest to measure the effects of GPSE on skin moisture, inhibition of skin cell proliferation, and anti-inflammatory activity on the damaged skin of HR-1 mice induced with ultraviolet B (UVB), and to verify the applicability of GPSE as a material for functional food and functional cosmetics. The polyphenol was extracted from grape pruning stems with 80% EtOH, and then the extract was used while storing at $-20^{\circ}C$, after filtering, concentrating, and freeze-drying it. The content of an active ingredient of GPSE was analyzed using high performance liquid chromatography (HPLC). From 53 kg of the grape pruning stem specimen, 2.34 kg of the EtOH fraction extracts were extracted to achieve a 4.42% yield ratio. Analysis of the active ingredients showed 0.28 mg/g of procyanidin B3, 12.81 mg/g of rutin, 0.51 mg/g of quercetin, and 8.24 mg/g of kaempferol. After UVB irradiation on the dermis, to confirm the degree of inhibition of collagen synthesis, we examined the protein expression of MMP-9 using immunohistochemical staining. The results of this study confirm the existence of active polyphenol types, such as rutin, kaempferol, quercetin, and procyanidin B3, in GPSE. Moreover, the study found that GPSE has anti-collagenase effects and it decreases the effects of UV damage on skin barrier function. GPSE is a functional ingredient with a potential for skin protection effects, and it has high utilization potential as an ingredient for functional cosmetics.

  • Acerola is an excellent ingredient because of its high natural vitamin C content, but it is difficult to stabilize and has hardly been studied as a cosmetic material. Therefore, this study developed a mixed liposome preparation for stabilizing acerola extract. As a safety test, the skin irritation test was evaluated by BCOP assay and HET-CAM assay. We evaluated the inhibition of tyrosinase activity, the whitening effect of melanin production, and the wrinkle effect of prochloragentype-I C-peptide production, and confirmed the possibility of functional cosmetics. In addition, a cream of liposomes containing acerola extract mixture was developed to evaluate the clinical studies of skin wrinkles and whitening. BCOP assay, HET-CAM assay and human skin primary irritation test results of liposomes containing acerola extract mixture showed no irritation and were safe from skin and eye. The result of tyrosinase activity by 75.8% at 1,000 ㎍/mL. As a result of the melanogenesis inhibition test, liposome with acerola extract showed the melanin content by 46.2% at 1,000 ㎍/mL that does not effect the viability of the B16F10 cell line. The result of collagen production test using ELISA kit, liposomes containing acerola extract mixture showed collagen synthesis ability by 152.1% at 1,000 ㎍/mL that does not affect the viability of the HS68 cell line. But it did not showed any inhibition of collagenase (MMP-1) activity at all concentrations in the MMP-1 activity inhibition test in the HS68 cell line. We performed clinical studies for the whitening and skin-wrinkle activity of cream containing acerola extract mixes liposome, was showed that the melanin contents and wrinkle was statistically significant reduction. These results suggest that liposomes containing acerola extract mixture have safe natural material, and skin wrinkle, whitening effects allowing their application in cosmetics as a natural product.

  • Objective: To investigate the effect of Alpiniae oxyphyllae fructus (AOF) on the alleviation of musculoskeletal disorders caused by aging, we conducted experiments on osteoporosis and muscle atrophy. Methods: The experimental group was classified into a control group, aging-elicited (AE) group and AOF group. The control group comprised 8-week-old Institute of Cancer Research (ICR) mice. The AE and AOF groups were ICR mice at 50 weeks of age. For the AE group, 10 mL of distilled water was administered once a day for 180 days without any treatment. An AOF extract (0.54 g/kg) was dissolved in distilled water and administered to the mice in the AOF group once a day for 180 days. Results: In the experiment on the alleviation of osteoporosis, the distribution of glucosaminoglycan in the bone matrix of the femoral bone was increased in the AOF group; moreover, the osteocalcin (OCN) positive reaction was increased and 8-OHdG positivity was decreased. In addition, AOF positively decreased RANKL, positively increased OPG, and positively decreased MMP-3. Muscle fiber loss in the endomysium following muscle degeneration of the quadriceps was reduced more in the AOF group compared with the AE group, and caspase-3 positive responses were also decreased. In addition, the 8-OHdG and p-lkB positivity in the AOF group decreased compared with the AE group, and the Myo-D positivity increased. Conclusion: We found that increasing bone formation alleviates osteoporosis, and that reducing bone loss alleviates muscle atrophy by reducing muscle loss and increasing muscle development.

  • Gamimahaenggamsuk-tang (GMHGST) is used for treatment of inflammatory diseases including rheumatoid arthritis (RA). Here, regulatory activity of GMHGST on RA-mediated inflammatory responses was investigated in cultured human fiDroblast-like synoviocytes (FLS), Levels of mRNAs encoding for inflammatory cytokines such as $IL-1{\beta}$, IL-6 and IL-8 and NOS-II enzyme, which had been induced by $TNF-{\alpha}$ and $IL-1{\beta}$ cotreatment, were decreased to the similar levels as those in cells treated with anti-inflammatory agent MTX. mRNA expressions of matrix metalloproteinase-3 (MMP-3) and tissue inhibitor of metalloproteinases (TIMPs) as well as intercellular adhesion molecule (ICAM) were also downregulated by increasing doses of GMHGST in activated FLS. Moreover, GMHGST appeared to protect cells by decreasing NO levels, and inhibited cell proliferation which had been induced by inflammatory stimulation by $TNF-{\alpha}$ and IL-1. These results suggest that GMHGST is effective as an inhibitory agent for regulating inflammatory responses in activated FLS.

  • Adenoid cystic carcinoma (ACC) of salivary glands has a protracted clinical course with perineural invasion, delayed onset of hematogenous metastasis, and poor responses to classical cytotoxic chemotherapic agents. Most deaths from salivary ACC are caused by lung metastases that are resistant to conventional therapy. Therefore, knowledge of cellular properties and tumor-host interactions that influence the dissemination of metastatic cells is important for the design of more effective therapy of salivary cancer. I determined in vitro expression of epidermal growth factor receptor (EGFR) and its downstream effectors and vascular endothelial growth factor receptor (VEGFR)-2 on a human salivary ACC cell line (ACC2). I also evaluated the expression of EGF and VEGF signaling molecules and metastasis-related proteins on human salivary ACC cells orthotopically growing in nude mice. In Western blot and immunohistochemical analyses, EGFR and VEGFR-2 were presented and phosphorylated in ACC2 cells. In human parotid cancer xenografts in nude mice, EGF and VEGF signaling molecules, IL-8, and MMP-9 were expressed at markedly higher levels than in normal parotid tissues. Moreover, tumor-associated endothelial cells of this orthotopic parotid tumor expressed phosphorylated VEGFR-2 and phosphorylated Akt, which is a cell-survival protein. These data show that those biomarkers can be molecular targets for therapy of salivary ACC, which has a propensity for delayed lung metastasis.
