  • Objectives : Platycodon Root is frequently used in traditional medicine to treat inflammatory diseases of the throat. The purpose of this study was to characterize the effect of the EtOH extract of fermented Platycodon grandiflorum on the ameliorative effects on the Antipruritic Effect of atopic dermatitis mouse model induced by compound 48/80 and ovalbumin (OVA)-induced allergic responses in mice. Methods : In the present study, we examined the anti allergic effect of Platycodon grandiflorum (PR) and its fermented production (FPR) in several mouse model. We measured acute ear edema in a mouse model caused by TPA and consecutively histological change of Ear tissue was observed by hematoxylin and eosin (H&E) staining. and also Scratching behaviors by compound 48/80 was investigated. The levels of allergic mediators such as immunoglobulin (Ig) E, and anti-oxidant markers such as SOD and MDA in the sera of OVA induced allergic mice were measured by enzyme-linked immunosorbent assay. Results : FPR inhibited compoud 48/80-induced scratching behavior in mice, as well as acetic acid-induced writhing in mice. The anti-scratching behavioral effect of FPR was more potent than PR. FPR extract significantly decreased the serum levels of IgE and MDA compared with those of OVA control group. Conclusions : These results indicate that Anti allergic effect of Platycodon grandiflorum is enhanced by fermentation with Saccharomyces cerevisae and FPR may be useful for protection from the itching reactions, which are IgE-mediated representative skin allergic diseases.

  • Objectives Medical plant has a big role in Herbal Medicines, and most medical plant has phytoestrogens. Therefore some estrogenic effects have been reported in a lot of Korean Medicine literature. Phytoestrogens should be used carefully in children. The objective of this study is to identify reported phytoestrogenic effects in Herbal Medicines and to evaluate the characteristics of the phytoestrogens in Herbal Medicines. Methods A literature search was done with using 8 databases with a limit of reports until 12/31/2013. The estrogenic effects were summarized by each individual Korean Medicine. The frequency of the phytoestrogens was also investigated depending on the Korean medical categorization by the treatment effect. Results and Conclusions Phytoestrogenic effects were reported in 89 Herbal Medicines. Phytoestrogens were act bidirectionally, and the effect was fairly weak compared to estrogen. Phytoestrogenic effect was variable on different cells and tissues. The most frequent phytoestrogenic effect was in tonifying and replenishing medicinal, the following orders were heat-clearing, exterior-releasing, and blood-activating and stasis-dispelling medicinal. Phytoestrogens were not reported in dampness-resolving, digestant, orifice-opening, emetic medicinal.

  • Objectives : ROS are involved in a wide spectrum of diseases including chronic inflammation and cancer. S.chinensis Baill, a perennial herb commonly called Chinese lizard's tail or Sam-baek-cho in Korea, is used for the treatment of edema and inflammatory diseases in the Oriental folk medicine. In this study, we investigated the antioxidant activities and anti-inflammatory effects of the two extracts, water(WE) and ethyl acetate(EAE) from S.chinensis Baill. Methods : Anti-oxidant activity was evaluated using Fe2+ chelating and hydroxyl radical scavenging assay. DNA cleavage assay, and western blot and immunostaining for phospho-p65 were performed to evaluate anti-oxidative effect. Anti-inflammatory effect was performed using NO generation assay and western blot in LPS-stimulated RAW264.7 cell. Results : In Fe2+ chelating activity and hydroxyl radical scavenging activity, WE showed more strong scavenging activity for hydroxyl radical than EAE. WE scavenged hydroxyl radical by 12% at 3.2 ${\mu}g/ml$, 21% at 16 ${\mu}g/ml$, 32% at 80 ${\mu}g/ml$, 66% at 400 ${\mu}g/ml$ and 82% at 2000 ${\mu}g/ml$, respectively. In addition, WE showed more strong chelating activity than EAE. WE chelated Fe2+ ion by 1.1% at 3.2 ${\mu}g/ml$, 8.2% at 16 ${\mu}g/ml$, 26.3% at 80 ${\mu}g/ml$, 72% at 400 ${\mu}g/ml$ and 89% at 2000 ${\mu}g/ml$, respectively. Also, WE inhibited oxidative damage via its anti-oxidant activity. In anti-inflammatory effect, EAE inhibited NO production and iNOS expression. In addition EAE suppressed the NF-${\kappa}B$ and MAPK signaling pathway in LPS-stimulated RAW 264.7 cells. Conclusions : Together, these data indicate that S. chinensis Baill, shows anti-oxidant activity and anti-inflammatory effect.

  • Honey used as conventional medicine has various pharmacological properties. In the honey and anti-inflammatory effect, Gelam honey and Manuka honey has been reported to exert anti-inflammatory activity. However, the anti-inflammatory effect and potential mechanisms of acacia honey (AH) are not well understood. In this study, we investigated anti-inflammatory activity and mechanism of action of AH in LPS-stimulated RAW264.7 cells. AH attenuated NO production through inhibition of iNOS expression in LPS-stimulated RAW264.7 cells. AH also decreased the expressions of $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ as pro-inflammatory cytokines, and MCP-1 expression as a pro-inflammatory chemokine. In the elucidation of the molecular mechanisms, AH decreased LPS-mediated $I{\kappa}B-{\alpha}$ degradation and subsequent nuclear accumulation of p65, which resulted in the inhibition of $NF-{\kappa}B$ activation in RAW264.7 cells. AH dose-dependently suppressed LPS-mediated phosphorylation of ERK1/2 and p38 in RAW264.7 cells. In addition, AH significantly inhibited ATF2 phosphorylation and nuclear accumulation of ATF2 in LPS-stimulated RAW264.7 cells. These results suggest that AH has an anti-inflammatory effect, inhibiting the production of pro-inflammatory mediators such as NO, iNOS, $TNF-{\alpha}$, IL-6, $IL-1{\beta}$ and MCP-1 via interruption of the $NF-{\kappa}B$ and MAPK/ATF2 signaling pathways.

  • It is very important factors to control optimal light transmission ratio and soil moisture content in order to produce good quality of ginseng seedling. To study the effect of light transmission ratio (LTR) and soil moisture content(SMC) on growth characteristics and yield of ginseng seedling, LTR was controlled by three level such as 21.2, 24.8% and 30.3%, and SMC was plotted by four level of 11.0%, 12.5%, 15.3% and 18.9% at the greenhouse. Chlorophyll content was gradually decreased in the low LTR (21.2%), while it was distinctly decreased by the decrease of SMC in excessively high LTR (30.3%). The decrease of SMC in the high LTR increased heat injury ratio distinctly, while heat injury ratio in the low LTR was only increased when SMC was very low such as 11.0%. All of fresh root weight per Kan (3.3$m^2$), root weight per plant, and the number of usable seedling were distinctly decreased by the increase of LTR and the decrease of SMC. Excessive increase of LTR in optimal SMC (18.9%) hadn't a great effect on the decrease of root weight, while root weight in low SMC was distinctly decreased by the increase of LTR. Ratio of rusty root was distinctly increased in the condition that both of LTR and SMC were high. Ratio of rusty root in the excessively high LTR was gradually fallen off by decrease of SMC, but its ratio in low SMC didn't changed distinctly by the decrease of SMC.

  • Objectives : This study aims to analyze the terms describing anti-aging effects in Dongeuibogam, and to propose the methodology for selecting medicinal herbs related to anti-aging effects. Methods : We considered aging or anti-aging theories by reviewing the major literature in korean medicine or traditional chinese medicine, and then we deduced the concepts describing anti-aging effects and the medicinal herbs for anti-aging effects. We investigated the medicinal herbs based on the terms describing anti-aging effects in Dongeuibogam and drew the methodology for selecting and classifying the medicinal herbs related to anti-aging. Results & Conclusions : The following conclusions could be drawn. 1. A set of causes and signs of aging in Dongeuibogam and a set of therapies for alleviating the aging signs in Chengumikbang, Yanglobongchinseo, and Nolohangeon was found. 2. Anti-aging effects should not be confused with disease treatments. Therefore, we defined the medical terms of anti-aging effects as "the terms expressing the effect of delaying or alleviating the subjective or objective signs of aging concretely". Based upon the terms of anti-aging effects, we defined the medicinal herbs for anti-aging effects as "the medicinal herbs whose effects are described in medical terms expressing the effects of delaying or alleviating the subjective or objective signs of aging concretely". 3. We considered Lycii Fructus, Asparagi Tuber in Dongeuibogam as examples of medicinal herbs whose effects are described in medical terms expressing anti-aging effects. It shows that we can select medicinal herbs for anti-aging effects by comparing the effects of 937 single therapies in Dongeuibogam to the terms describing anti-aging effects defined in this study. Futhermore, the results could be utilized as the basic materials of experimental study on anti-aging.
