  • Epimedii Herba is an important traditional herb medicine widely used as a tonic. However, the mechanism of action of this drug on the immune system is not well studied. This study was performed to elucidate the effects of the aqueous extract of Epimedii Herba on the production of antibodies in mice. Antibodies in serum were detected in male ICR mice treated with the aqueous extract of Eplmedii Herba (AEEH) at a dosage of 40, 120, and 360mg/kg orally for 2 weeks. Effects of oral administration of AEEH on antibody forming responses were measured by enzyme linked immunosorbent assay (ELISA) of immunoglobulin (Ig) levels in serum. The results were as follows; 1. Epimedii Herba slightly decreased body weight gain. 2. Epimedii Herba significantly increased the relative spleen weight. 3. Epimedii Herba significantly increased total serum IgG levels. 4. Epimedii Herba significantly enhanced total serum IgG1 levels. 5. Epimedii Herba significantly increased total serum IgG2a levels. 6. Epimedii Herba markedly increased total serum IgM levels. These findings demonstrate that Epimedii Herba significantly enhances the production of antibodies at therapeutic concentrations, and suggest that administration of Epimedii Herba may prevent the host from immunologic diseases.

  • Atopic dermatitis (AD) is an inflammatory skin condition accompanied by symptoms such as edema and hemorrhage. Kimchi is a traditional fermented Korean dish consisting of various probiotics. In this study, the therapeutic effect of Lactobacillus plantarum CJLP55 isolated from Kimchi was studied in AD-induced mice. Orally administered Lactobacillus strain, CJLP55, suppressed AD symptoms and high serum IgE levels. CJLP55 administration reduced the thickness of the epidermis, infiltration of mast cells and eosinophils into the skin lesion, enlargement of axillary lymph nodes, and increase in cell population in axillary lymph nodes. CJLP55 treatment decreased the production of type 2 cytokines, such as interleukin (IL)-4, IL-5, IL-10, IL-12, interferon (IFN)-${\gamma}$, and IL-6,which were stimulated by house dust mite extracts, in the axillary lymph node cells. Orally administered CJLP55 exhibited a therapeutic effect on house dust mite-induced AD in NC/Nga mice after onset of the disease by altering immune cell activation. The Lactobacillus strain, CJLP55, isolated from Kimchi, suppressed AD. Our results suggest its possible use as a potential candidate for management of AD.

  • Scutellaria barbata D. Don (S. barbata), a traditional Chinese medicine, is used to treat cancers, inflammation, and urinary diseases. This study aimed to determine any protective effects of S. barbata crude extract (CE-SB) against rat liver tumorigenesis induced by diethylnitrosamine (DENA). Liver malfunction indices in serum were measured by biochemical examination. Hematoxylin and eosin staining was performed to examine liver pathology. Contents of malondialdehyde (MDA) and superoxide dismutase (SOD) were measured in liver homogenates to evaluate oxidative stress. The levels of liver malfunction indices in the CE-SB groups, especially in the CE-SB high dose group, were lower than that of the model group (P<0.05). The results from histological examination indicated that the number of liver nodules in the CE-SB groups decreased compared with the model group (P<0.05). Content of MDA determined in liver was significantly decreased, and level of SOD elevated by CE-SB. CE-SB can inhibit experimental liver tumorigenesis and relieve hepatic injury in rats.

  • In the present study, three Malaysian Channa spp. fish Channa striatus, Channa micropeltes and Channa lucius were assessed for their analgesic activity. Distilled water and mixture of chloroform: methanol were used for extraction. The analgesic or antinociceptive activity was investigated by abdominal writhing and hot plate test. The water extract of Channa striatus and the chloroform: methanol extract Channa lucius produced potent antinociceptive effect when assessed with the abdominal writhing test. The activity was compared to morphine where the activity of the extracts was less potent than the opioid. In the hote plate test, water extract of Channa striatus revealed significant activity and chloroform:methanol extract of Channa micropeltes had moderate activity. However, these activities were statistically lower than morphine. Collectively, this study also showed that Channa striatus extract was more potent analgesic agent when compared to the other closely related snakehead Channa micropeltes and Channa lucius.

  • This study investigated the role of Panax ginseng (PG) on the phorbol myristate acetate (PMA) + calcium ionophore A23187-induced hypoxia-inducible factor-$1{\alpha}$ (HIF-$1{\alpha}$) activation, phosphorylation of the extracellular signal-regulated kinase (ERK), and inflammatory cytokine production from the human mast cell line, HMC-1. HIF-$1{\alpha}$ and phosphorylation of ERK were observed by Western blotting. The inflammatory cytokine production was determined by enzyme-linked immunosorbent assay. PG inhibited the PMA+A23187-induced HIF-$1{\alpha}$ expression and the subsequent production of vascular endothelial growth factor. In addition, PG suppressed PMA + A23187-induced phosphorylation of ERK. We also show that the increased cytokines interleukin (IL)-$1{\beta}$, IL-6, and tumour necrosis factor-${\alpha}$ level was significantly inhibited by treatment of PG. In the present study, we report for the first time that PG is an inhibitor of HIF-$1{\alpha}$ and cytokines on the mast cell-mediated inflammatory responses.

  • Objectives The aim of this review is to analyse the study tendency in papers related with delphi method which are published in Korea from 2006 to 2015. Methods We searched the electronic database (NDSL, RISS, Korean traditional knowledge portal, OASIS) and checked relevant Korean journals from 2006 to 2015. 23 research papers were found and they were analyzed according to the year of publishment, the titles of journals which have the papers, the time of repeated survey and purpose of technique application. Results 1. As we analyzed by years, 2.3 papers were published per year on average. 2. As we analyzed by jounals in which papers were published, 39% of total papers were published in The Journal of the Society of Korean Medicine Diagnostics, 30% were in Korean Journal of Oriental Physiology & Pathology, taking up 69% of total papers. 3. As we analyzed by the number of survey taken in each research, 11 papers surveyed 2 times, 7 papers surveyed 3 times, 1 paper suerveyed one time. 4. As we analyzed by the purpose of technique application, 91% of papers were aimed at the development of questions, 9% of papers were aimed at policy recommendation. Conclusions These results suggest that although many researches were trying to quantify the symptom of patient, to demonstrate on exact data and to accomplish the scientification of diagnosis, the number of paper is insufficient. Therefore, it seems that more researches must be taken afterward.

  • A variety of anti-inflammatory agents have been shown to exert chemopreventive activity via targeting of transcription factors such as NF-${\kappa}B$ and AP-1. Lithospermum erythrorhizon (LE) has long been used in traditional oriental medicine. In this study, we demonstrated the inhibitory effects of LE extracts on lipopolysaccharide (LPS)-stimulated production of inflammatory cytokines. As an underlying mechanism of inhibition, LE extracts reduced LPS-induced transactivation of AP-1 as well as NF-${\kappa}B$ in mouse macrophage cells. Electrophoretic mobility shift assays indicated that LE extracts inhibited the DNA binding activities of AP-1 and NF-${\kappa}B$. In addition, phosphorylation of $I{\kappa}B-{\alpha}$ protein was suppressed by LE extracts. Moreover, LE extracts inhibited c-Jun N-terminal kinase and extracellular signal-regulated signaling pathways. Our results suggest that the anti-inflammatory activity of LE extracts may be mediated by the inhibition of signal transduction pathways that normally lead to the activation of AP-1and NF-${\kappa}B$. These inhibitory effects may be useful for chemoprevention of cancer or other chronic inflammatory diseases.

  • Hepatic fibrosis is one of chronic liver diseases which spread in worldwide and it has high risk to turn advanced cirrhosis and hepatocellualr carcinoma. Brassica family has been produced for commercial purpose and in Korea Brassica rapa (Turnip) is cultivated in Ganghwa County, Gyeonggi-do Korea and used for making Kimchi. Recently pharmacological effects of turnip have been known; diabete mellitus modulation, alcohol oxidization, and fibrosis inhibition. In previous study we found antifibrogenic effect of turnip water extract and in this study we made turnip nanoparticle to promote turnip delivery into liver. At the same time we assessed the biological safety of turnip nanoparticle. Thioacetamide (TAA) induced hepatic nodular formation and fibrosis (mean of fibrosis score: 4). However, 1% turnip nanoparticle inhibited TAA-induced hepatic nodular formation and fibrosis (mean of fibrosis score: 2-3). Activities of serum enzymes (aspartic acid transaminase (AST), alanine transaminase (ALT), and total bilirubin (T-Bil)), complete blood count (CBC), and the appearance of organs were not different from control and 1% turnip nanoparticle treatment. Conclusively 1% turnip nanoparticle significantly reduced TAA-induced hepatic fibrosis and was safe in 7-weeks feeding.

  • The Purpose of the study is to give Korean-English leaners better knowledge on vowel sounds in their learning English. The traditional description of the cardinal vowel system developed by Daniel Johns in 1917 is not enough to provide English learners with clear ideas in producing native like vowel sounds. For the reason, three Korean-native subjects, one male, one female and one child are chosen to produce 7 cardinal vowels and compare them with native English and American speaker's vowel sounds. The difference of produced vowels sounds is quantified and visualized by employing Sona-match program. The results have been fairly remarkable. Firstly, Korean-English learner's vowel sounds are articulated differently from their intention of vowel production. Secondly, the tongue positions of Koreans are placed slightly more down and forward to the lips than those of English and Americans. However, the front vowel /i/ sound is quite close to English and Americans. Lastly the mid-vowel /${\partial}$/ sound is not produced in any articulations of Korean-native speakers. It is thought that the mid vowel, /${\partial}$/ is a type of a weak sound regarded as 'schwa' which needs a great deal of exposure to the language to acquire a physical skill of articulation.

  • We examined the radioprotection effects of acupoint (acupuncture point) stimulation during organogenesis stages of ICR mice. Pregnant mice received 1.5 Gy whole body X-irradiation on day 8 of gestation, which is the early stage of organogenesis. The embryonic death rate and teratogenesis rate by radiation were examined. Electroacupuncture to the leg acupoints and/ or transcutaneous stimulation to the back acupoints on the pregnant mice showed no protective effect against irradiation on embryonic or fetal death rate. On the contrary, the strong stimulation resulted in increase in the mortality after irradiation rather than protection. However acupoint stimulation to the pregnant mice never showed harmful effects by itself on embryos. It tended to reduce the skeletal malformations induced by X-ray irradiation. We suspect that acupoint stimulation removed the cells injured by irradiation during embryonic development, resulting in an increase in embryonic death rate and reduction in skeletal anomalies.
