Korean traditional herbs, especially Anemarrhena asphodeloides (A. asphodeloides), Salvia miltiorrhiza (S. miltiorrhiza), and Terminalia chebula (T. chebula) have been known to have the immunomodulatory, anti-tumor, and anti-inflammatory effects. However, direct cellular mechanism underlying the mast cell-mediated anaphylaxis-like reaction has poorly been understood. In the present study, the effects of the methanol extracts of A. asphodeloides (MEAA), S. miltiorrhiza (MESM), and T. chebula (METC) on anaphylactic reaction were investigated. Using in vitro and in vivo experiments, the influences of MEAA, MESM, and METC on the compound 48/80-induced anaphylaxis-like reaction and mast cell activation, and IgEmediated PCA were examined. Results are below; 1) MEAA, MESM, and METC significantly inhibited systemic anaphylaxis-like reaction, ear swelling response, and IgE-mediated PCA. 2) the compound 48/80-induced mast cell degranulation, histamine release of rat peritoneal mast cells (RPMC) were significantly inhibited by the pretreatment with MEAA, MESM, and METC, and 3) the compound 48/80-induced calcium influx in RPMC was significantly inhibited by the pretreatment with MEAA, MESM, and METC. These results suggest that MEAA, MESM, and METC may be an activity to inhibit the compound 48/80-induced or anti-DNP IgE-mediated anaphylactic reactions by blocking histamine release and calcium uptake into RPMC. MEAA, MESM, and METC potentially may serve as an effective therapeutic tool for allergic diseases.

Objective : This study was designed to investigate the effect of the water extract of Gamisamgibopae-tang(GMSGBPT), an oriental herbal formulation, on the growth of NCI-H460 and A549 human non-small-cell lung cancer cell lines. Methods : Cytotoxicity and cell morphology were evaluated by MTT assay and inverted microscope, respectively. Apoptosis was detected using agarose gel electrophoresis and flow cytometer. The expression levels of mRNAs and proteins of target genes were determined by RT-PCR and western blot analyses, respectively Result and Conclusion : We found that exposure of A549 cells to GMSGBPT resulted in the growth inhibition in a dose-dependent manner as measured by MTT assay, but GMSGBPTdid not affect the growth of NCI-H460 cells. The anti-proliferative effect of GMSGBPT treatment in A549 cells was associated with morphological changes, formation of apoptotic bodies and DNA fragmentation, and flow cytometry analysis confirmed that GMSGBPT treatment increased the populations of apoptotic-sub G1 phase. Growth inhibition and apoptotic cell death by GMSGBPT were connected with a up-regulation of cyclin-dependent kinase inhibitor p21 (WAF1/CIP1) mRNA and protein in a tumor suppressor p53-independent fashion. However GMSGBPT treatment did not affect other growth regulation-related genes such as early growth response-1 (Egr-1), nonsteroidal anti-inflammatory drug (NSAID)-activated gene-1 (NAG-1), inducible nitric oxide synthase (iNOS), cyclooxygenases (COXs), telomere-regulatory factors in A549 orNCI-H460 cells. Taken together, these findings partially provide novel insights into the possible molecular mechanism of the anti-cancer activity of GMSGBPT.

Fibroblasts are major cellular components of gingiva and periodontal ligament. They regulate the healing process after surgery or injury. Recently, many natural medicines, whose advantages are less side effects and possibility of long-term use, have been studied for their capacity, their anti-bacterial and anti-inflammatory effects and regenerative potential of periodontal tissues. Sophorae radix have been traditionally used as an anti-bacterial and antiinflammatory drug in oriental medicine. The purpose of present study was to investigate the effects of Sophorae radix extract on cell cycle progression and its molecular mechanism in human gingival fibroblasts. Sophorae radix extracts($100{\mu}g/ml$) notably increased cell proliferation and cell activity in the human gingival fibroblasts as compared to non-supplemented controls. There was an increase in the S phase and a decrease in the G1 phase in $100{\mu}g/ml$ of Sophorae radix extracts group as compared to non-supplemented controls. The level of cyclin E and cdk 2 protein in test group was higher than that of control groups. But that of cyclin D, cdk 4, and cdk 6 was not distinguished from controls. The level of p53 protein in test group was lower than that of controls, whereas that of p21 was not different. The level of pRB protein in test group was higher than that of controls, whereas that of p16 was lower. These results indicate that the increase of cell proliferation by Sophorae radix extracts may be due to the increased expression of cyclin E and cdk 2, and the decreased expression of p53 and p16 in human gingival fibroblasts.

Hwangryunhaedok-tang (HRT) is a traditional herbal medicine, which has been known as a useful prescription for anti-biotic, anti-inflammatory, anti-oxidative and immunosuppressive activity. In this study, the variation in the amount of eight bioactive components of Hwangryunhaedok-tang (HRT) and its fermentation HRT with Lactobacillus casei KFRI 127, Lactobacillus curvatus KFRI 166 and Lactobacillus confuses KFRI 227 was investigated via high-performance liquid chromatography coupled with diode array detection (HPLC-DAD). Simultaneous qualitative and quantitative analysis of eight bioactive components; geniposide, genipin, baicalin, wogonoside, palmatine, berberine, baicalein and wogonin was achieved by comparing their retention times ($t_R$) and UV spectra with those of the standard components. All calibration curve of standard components showed good linearity ($r^2$ >0.979). As a result, the geniposide amount was $15.52{\pm}0.19{\mu}/mg$ that as a main components in HRT. The wogonoside was decreased by 29.28~58.35% with Lactobacillus casei KFRI 127 and L. confuses KFRI 227 ($3.17{\pm}0.31{\mu}g/mg$ and $3.55{\pm}0.13{\mu}g/mg$) compared with the original HRT ($5.02{\pm}0.14{\mu}g/mg$). Otherwise wogonin was increased by 16.28~41.86% with Lactobacillus casei KFRI 127 and L. confuses KFRI 227 ($0.61{\pm}0.01{\mu}g/mg$ and $0.50{\pm}0.02{\mu}g/mg$) compared with the original HRT($0.43{\pm}0.00{\mu}g/mg$). HRT fermented with L. casei KFRI 127 and L. confuses KFRI 227 were evaluated as creating the changes in wogonoside to that aglycon wogonine. In the fermented HRT using Lactobacillus acidophilus KFRI 166, the genipin was only detected, among 3 species of fermentation strains. Thus, these results considered that the strains 166 were exhibited the remarkable changes in genipin.

The fruit of Hippophae rhamnoides has been widely used for medicinal purposes because of its anti-inflammatory, antioxidant, antiplatelet, and antimicrobial effects. Since there are no clear reports on the therapeutic efficacy of H. rhamnoides in osteoporosis, this study aimed to confirm the potential use of H. rhamnoides for the treatment of osteoporosis through its osteogenic differentiation-promoting effect in ovariectomized mice. Through an in vitro study, we compared the effects of the EtOH extract of H. rhamnoides fruits (EHRF) on the differentiation of C3H10T1/2, a mouse mesenchymal stem cell line, into osteoblasts based on alkaline phosphatase (ALP) staining and the relative expression of osteogenesis-related mRNAs. The EHRF significantly stimulated the differentiation of mesenchymal stem cells into osteoblasts and showed 7.5 times (^* p < 0.05) higher osteogenesis than in the untreated control. A solvent fractionation process of EHRF showed that the hexane-soluble fraction (HRH) showed 10.4 times (^** p < 0.01) higher osteogenesis than in the untreated control. Among the subfractions derived from the active HRH by preparative HPLC fractionation, HRHF4 showed 7.5 times (^* p < 0.05) higher osteogenesis than in the untreated naïve cells, and HRH and HRHF4 fractions showed 22.6 times (^*** p < 0.001) stronger osteogenesis activity than in the negative control. Osteoporosis was induced by excision of both ovaries in 9-week-old female ICR mice for in vivo analysis, and two active fractions, HRH and HRHF4, were administered orally for three months. During the oral administration period, body weight was measured weekly, and bone mineral density (BMD) and body fat density were measured simultaneously using a DEXA machine once a month. In particular, during the in vivo study, the average BMD of the ovariectomized group decreased by 0.0009 g/cm², whereas the average BMD of the HRH intake group increased by 0.0033 g/cm² (^* p < 0.05) and that of the HRHF4 intake group increased by 0.0059 g/cm² (^** p < 0.01). The HRH and HRHF4 intake groups significantly recovered the mRNA and protein expression of osteogenic genes, including ALP, Osteopontin, Runx2, and Osterix, in the osteoporosis mouse tibia. These findings suggest that the active fractions of H. rhamnoides fruit significantly promoted osteoblast differentiation in mesenchymal stem cells and increased osteogenic gene expression, resulting in an improvement in bone mineral density in the osteoporosis mouse model. Taken together, H. rhamnoides fruits are promising candidates for the prevention and treatment of osteoporosis.

In infectious disease, invasion of host tissue by bacteria or their products frequently induces a wide variety of inflammatory and immunopathologic reaction. Evidence indicates that cytokines are involved in the initiation and progression of chronic inflammatory diseases, such as periodontitis. Interleukin-6, which is a multifunctional cytokine, has important roles in acute and chronic inflammation and may also be implicated in bone resorption. Periodontal diseases are characterized by chronic inflammation of the periodontium with alveolar bone resoption. A principal driving force behind this response appears to lie in the immune system's response to bacteria. Many of the cell components which have been shown to function as virulence factors in gram-negative bacteria are associated with the bacterial surface. Of these, lipopolysaccharide has been characterized as one that mediates a number of biological activities which can lead to the destruction of host tissue. Non-steroidal antiinflammatory drug is used for reduce inflammation, and most of NSAIDs inhibit prostaglandine $E_2$ production, but it is shown that $PGE_2$ production is stimulated by IL-1 in recent study. So, the influence of other cytokines except $PGE_2$ on periodontium can not be avoided. Therefore, new antiinflammatory drug is needed. Rhizoma coptidis is used in oriental medicine for anti-inflammation and antiseptics. In this present study, we examined the IL-6 release in periodontal ligament cells treated with the lipopolysaccharide, and also the effect of rhizoma coptidis on cellular activity and IL-6 production of periodontal ligament cells. To evaluate the effect of rhizoma coptidis on cellular activity, the cells were seeded at a cell density of $1{\times}10^4$ cells/well in 24-well culture plates. After one day incubation, 1-6, 10-9 and 10-12 g/ml of rhizoma coptidis and 5, $10{\mu}g/ml$ of LPS were added to the each well and incubated for 1 and 2 days, respectively. Then, MTT assay were carried out. To evaluate the effect of rhizoma coptidis on IL-6 production, the cells were seeded at a cell density of $1.5{\times}10^4$ cells/well in 24-well culture plates. After one day incubation, 10-9 g/ml of rhizoma coptidis and 5, $10{\mu}g/ml$ of LPS were added to the each well and incubated for 3, 6, 12 and 24 hours. Then, amounts of IL-6 production is measured by IL-6 ELISA kit used. The results were as follows : 1. Rhizoma coptidisrbelow to ($10^{-6}g/ml$) significantly increaed cellular activity of periodontal ligament cells than control. 2. Rhizoma coptidist ($10^{-9}g/ml$) significantly increased cellular activity of LPS($5{\mu}g/ml$)-treated periodontal ligament cells than control. 3. LPS(5 and $10{\mu}g/ml$) significantly increased IL-6 production of periodontal ligament cells than control. 4. Rhizoma coptidis($10^{-9}g/ml$) decreased IL-6 production of LPS ($5{\mu}g/ml$)-treated periodontal.ligarnent cells than LPS only tested group. These findings suggest that stimulation of the IL-6 release of periodontal ligament cells by LPS may have a role in the progression of inflammation and alveolar bone resoption in periodontal disease, and that inhibition of the IL-6 release of cells and stimulation of cellular activity by rhizoma coptidis may help the periodontal regeneration.

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.

Sedum kamtschaticum Fisch., a native plant of Korea, has been used in Korean traditional medicine in the form of water extract for its capacity to improve blood circulation and for its antioxidant and anti-inflammatory effects. Since previous research suggests that S. kamtschaticum Fisch. has excellent antioxidant and mushroom tyrosinase inhibition activities, in this study, the root and stem parts of S. kamtschaticum Fisch. are extracted in 70% ethanol (SKS, SKR), fractionated with and in order of n-hexane (SSH), ethyl acetate (SSE, SRE), chloroform (SSC, SRC) and water (SSW, SRW) according to the polarity of each solvent, and tested for its applicability as a cosmetic material. According to the total polyphenol, flavonoid contents and DPPH radical scavenging activity of each fraction, the contents and scavenging activity of the root extractions (SKR) were higher than those of the stem extractions (SKS), ethyl acetate fractions (SSE, SRE) being the most effective. In addition, ethyl acetate fractions had the highest tyrosinase inhibition activity and melanin synthesis inhibition activity used on B16F10 melanoma cells, at the concentration of 10 ㎍/mL. HPLC analysis detected a variety of polyphenols including gallic acid and quercetin. This study suggests the potential role of S. kamtschaticum Fisch. as a natural cosmeceutical material.
