Protaetia brevitarsis (PB) extracts has been traditionally used as medicinal stuff to treat blood stasis, occlusion of menstruation, tetanus and liver cancer in Asian countries (Korea, Japan, China, Taiwan, India and Myanmar). Especially, Donguibogam, which is traditional korean medicinal book, described the PB extracts as traditional medicine to treat hepatic diseases and vascular disorders. The PB extracts has been considered as highly nutritional food. The major constituents of PB extracts are rich in protein, healthy fats, iron, calcium. Recent studies announced that PB extracts has hepatoprotective effect and anti-microbacterial effect. However, the effect of PB on ulcerative colitis has not been uncovered yet. The aim of this study was to examine the anti-inflammatory effect of PB extracts in dextran sulfate sodium (DSS)-induced colitis mice model. Cytotoxicity of PB was determined by MTT assay and the antiinflammatory effect of PB extract was investigated by measuring nitric oxide (NO) production. PB extracts did not show any cytotoxicity. AIso, PB extracts supressed NO production in LPS-stimulated mice peritoneal macrophages. To determine whether PB could be an effective treatment on ulcerative colitis, DSS was administered in BALB/c mice for 10 days. PB extract significantly improved the clinical signs of DSS-induced UC, including body weight loss, colon length shortening, and disease activity index increase, with histological markers of colon injury. These findings indicated the possibility of PB as a therapeutic agent on ulcerative colitis.

Objective : Hyperuricemia is a metabolic disease characterized by elevated blood uric acid levels, and its prevalence is rapidly increasing worldwide. Alpiniae Oxyphyllae Fructus (AO) belonging to Zingiberaceae is one of well-known traditional medicines in China and Korea, and has been used to treat intestinal disorders, urosis, diuresis, and chronic glomerulonephritis traditionally. However, the effect of AO has not been studied. In this study we investigated the anti-hyperuricemic effect of AO, and the mechanisms underlying the effect in potassium oxonate (PO)-induced hyperuricemic rats. Methods : To examine the anti-hyperuricemic effects of the AO extract, serum uric acid levels were analyzed in normal and PO-induced hyperuricemic rats. The mechanism underlying the effects of the AO extract on uric acid levels was studied through xanthine oxidase (XOD) activity test and uric acid uptake assay in vitro. The chemical finger printing of the AO extract was analyzed using HPLC-DAD. Results : The AO extract significantly reduced serum uric acid levels in normal as well as PO-induced hyperuricemic rats. It also significantly inhibited the uptake of uric acid in oocytyes and human embryonic kidney cells (HEK293) expressing urate transporter (URAT)1, but not XOD activity in vitro. The chemical finger printing analysis of the AO extract showed nootkatone as a main component. Conclusion : The AO extract exhibits anti-hyperuricemic effects, and these effect were accompanied by increasing excretion of uric acid in kidney. Therefore, the AO extract could be used for prevention or treatment of hyperuicemia and gout.

Background: Renal-cell carcinoma (RCC) is resistant to almost all chemotherapeutics and radiation therapy. ${\beta}$-Elemene, a promising anticancer drug extracted from a traditional Chinese medicine, has been shown to be effective against various tumors. In the present study, anti-tumor effects on RCC cells and the involved mechanisms were investigated. Methods: Human RCC 786-0 cells were treated with different concentrations of ${\beta}$-elemene, and cell viability and apoptosis were measured by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) assay and flow cytometry, respectively. Protein expression was assayed by western blotting. Autophagy was evaluated by transmission electron microscopy. Results: ${\beta}$-Elemene inhibited the viability of 786-0 cells in a dose- and time-dependent manner. The anti-tumor effect was associated with induction of apoptosis. Further study showed that ${\beta}$-elemene inhibited the MAPK/ERK as well as PI3K/Akt/mTOR signalling pathways. Moreover, robust autophagy was observed in cells treated with ${\beta}$-elemene. Combined treatment of ${\beta}$-elemene with autophagy inhibitors 3-methyladenine or chlorochine significantly enhanced the anti-tumor effects. Conclusions: Our data provide first evidence that ${\beta}$-elemene can inhibit the proliferation of RCC 786-0 cells by inducing apoptosis as well as protective autophagy. The anti-tumor effect was associated with the inhibition of MAPK/ERK and PI3K/Akt/mTOR signalling pathway. Inhibition of autophagy might be a useful way to enhance the anti-tumor effect of ${\beta}$-elemene on 786-0 cells.

BACKGROUND/OBJECTIVES: Several medicinal properties of Smilax china L. have been studied including antioxidant, anti-inflammatory, and anti-cancer effects. However, the antiobesity activity and mechanism by which the water-soluble fraction of this plant mediates its effects are not clear. In the present study, we investigated the lipolytic actions of the water-soluble fraction of Smilax china L. leaf ethanol extract (wsSCLE) in 3T3-L1 adipocytes. MATERIALS/METHODS: The wsSCLE was identified by measuring the total polyphenol and flavonoid content. The wsSCLE was evaluated for its effects on cell viability, lipid accumulation, glycerol, and cyclic adenosine monophosphate (cAMP) contents. In addition, western blot analysis was used to evaluate the effects on protein kinase A (PKA), PKA substrates (PKAs), and hormone-sensitive lipase (HSL). For the lipid accumulation assay, 3T3-L1 adipocytes were treated with different doses of wsSCLE for 9 days starting 2 days post-confluence. In other cell experiments, mature 3T3-L1 adipocytes were treated for 24 h with wsSCLE. RESULTS: Results showed that treatment with wsSCLE at 0.05, 0.1, and 0.25 mg/mL had no effect on cell morphology and viability. Without evidence of toxicity, wsSCLE treatment decreased lipid accumulation compared with the untreated adipocyte controls as shown by the lower absorbance of Oil Red O stain. The wsSCLE significantly induced glycerol release and cAMP production in mature 3T3-L1 cells. Furthermore, protein levels of phosphorylated PKA, PKAs, and HSL significantly increased following wsSCLE treatment. CONCLUSION: These results demonstrate that the potential antiobesity activity of wsSCLE is at least in part due to the stimulation of cAMP-PKA-HSL signaling. In addition, the wsSCLE-stimulated lipolysis induced by the signaling is mediated via activation of the ${\beta}$-adrenergic receptor.

The oriental medicine based on the traditional Chinese medicine has developed characteristically according to the history and racial character respectively; China, Korea and Japan. Japan, among these nations, has accepted western medicine earlier than other nations and has tried to compare western and oriental medicine and combine them. In Japanese traditional medicine, it is characteristic that the old medical classics focusing on Sanghannon (傷寒論) and Geumgyeyoryak(金?要略) has developed The recent tendencies of clinical medicine and researches in Korean oriental medicine are mostly about the study of oriental medicine in view of western medicine and the combination of western and oriental medical treatment like Japan. But the study on the Japanese oriental medicine hasn't so far been tried before in Korea. From now on, we should not overlook that a more interest on Japanese oriental medicine will be very useful. Therefore we have surveyed the background of its origin and the process of development of the theory of ${\ulcorner}$Qi, Blood and Body Fluids${\lrcorner}$. What we wish to show in this paper is to provide a source for the basic understanding by explaining a fundamental theory of physiology and pathology of Japanese oriental medicine. Concepts of ${\ulcorner}$Qi, Blood and Body Fluids${\lrcorner}$ suggested by Nangai Yoshimashi in 1792 is the way of thinking that the circulation of 3 factors- ${\ulcorner}$Qi, Blood and Body Fluids${\lrcorner}$ nourish human body. Among these 3 factors, if Qi does not function smoothly, it causes the condition of a disease like Qi-deficiency, imbalance of Qi-distribution or Qi-depression and stasis; in Blood's case, deficiency of Blood and Blood stasis; and as for Body Fluids, stasis of Body Fluids. In the recent trend of study, there's a try to combining the western and oriental medicine, Qi is considered as psychoneurotic system, Blood as circulatory and endocrinologic system and Body Fluids as immunologic system.

Background: The recent outbreak of the novel strain of influenza A (H1N1) virus has raised a global concern of the future risk of pandemic. Traditional Korean Medicine(TKM) has been combatting against contagious diseases and developed its own particular and efficient way in treating those diseases. Objectives: Provide a distinctive and effective TKM method in understanding the principles of treatment, prevention, and contraindications against influenza A through case histories. Method: We revised case histories of eminent doctors of Ming and Qing dynasties according to their clinical manifestations similar to those of influenza A. We also verified prescriptions of the "Dong-uibogam(東醫寶鑑)" through examining clinical practices of China today. Results: 1. The subtypes of Warm disease; Wind Warmth and Pestilence has the most similar clinical manifestation in comparison to Influenza A. Specifying these terms is important in recognizing and classifying various diseases under the name of Warm disease. 2. TKM considered not only external factors but also individual factors like general condition, diet, emotion, constitutional types, etc in the treatment of febrile diseases. 3. TKM developed a new way in the treatment of contagious diseases. considering the characteristics of each pathogen. TKM described the Warm pathogen being light as a feather, which enters through the nose, principally affecting the Lung. Therefore, they emphasized treatment with Pungent Sweet Cooling Moistening[辛甘凉潤] method. 4. As the conservation of fluid and humor is the primordial concern in the treatment of Warm disease, they restricted release of the exterior with pungent-warm and purgation method. The purgation methods was used exclusively to decrease fever and preserve fluid and humor. 5. The only differentiating characteristics of Influenza A with seasonal influenza are vomiting and diarrhea. Case research revealed the possibility of these manifestations to be a mechanism of restoration. 6. TKM provides alimento prevention method like Mint Pear Porridge, mung bean, and etc also combination of herbal medicine. Also emphasized in the conservation of essence for the prevention of contagious diseases. Conclusions: TKM developed its unique way in understanding the pathogenesis, diagnosis, treatment, and prevention of contagious diseases and formed its independent scheme of Warm Disease. This knowledge in febrile contagious disease is relevant today in providing diverse treatment and prevention for influenza A.

Background: In this study, we investigated how to convert the Panax ginseng DNA sequence code and chemical fingerprints into a two-dimensional code. In order to improve the compression efficiency, GATC2Bytes and digital merger compression algorithms are proposed. Methods: HPLC chemical fingerprint data of 10 groups of P. ginseng from Northeast China and the internal transcribed spacer 2 (ITS2) sequence code as the DNA sequence code were ready for conversion. In order to convert such data into a two-dimensional code, the following six steps were performed: First, the chemical fingerprint characteristic data sets were obtained through the inflection filtering algorithm. Second, precompression processing of such data sets is undertaken. Third, precompression processing was undertaken with the P. ginseng DNA (ITS2) sequence codes. Fourth, the precompressed chemical fingerprint data and the DNA (ITS2) sequence code were combined in accordance with the set data format. Such combined data can be compressed by Zlib, an open source data compression algorithm. Finally, the compressed data generated a two-dimensional code called a quick response code (QR code). Results: Through the abovementioned converting process, it can be found that the number of bytes needed for storing P. ginseng chemical fingerprints and its DNA (ITS2) sequence code can be greatly reduced. After GTCA2Bytes algorithm processing, the ITS2 compression rate reaches 75% and the chemical fingerprint compression rate exceeds 99.65% via filtration and digital merger compression algorithm processing. Therefore, the overall compression ratio even exceeds 99.36%. The capacity of the formed QR code is around 0.5k, which can easily and successfully be read and identified by any smartphone. Conclusion: P. ginseng chemical fingerprints and its DNA (ITS2) sequence code can form a QR code after data processing, and therefore the QR code can be a perfect carrier of the authenticity and quality of P. ginseng information. This study provides a theoretical basis for the development of a quality traceability system of traditional Chinese medicine based on a two-dimensional code.

Ginseng, the root of Panax species, is a well-known herbal medicine. It has been used as traditional medicine in Korea, China and Japan for thousands of years and now is a popular and worldwide natural medicine. The active principles of ginseng are ginsenosides which are also called ginseng saponins. Traditionally ginseng has been used primarily as a tonic to invigorate weak body functions and help the restoration of homeostasis. Current in vivo and in vitro studies demonstrate its beneficial effects in a wide range of pathological conditions such as cardiovascular diseases, cancer, immune deficiency and hepatotoxicity. Moreover, recent research indicates that some of ginseng's active ingredients exert beneficial actions on aging and neurodegenerative disorders such as Parkinson´s disease. Essentially, antioxidant, antiinflammatory, anti-apoptotic and immunostimulant activities are mostly underlying the postulated ginseng-mediated protective mechanisms. Next to animal studies, data from neural cell cultures contribute to the understanding of these mechanisms which involve decreasing nitric oxide, scavenging of free radicals and counteracting excitotoxicity. This paper focuses on own and other neuroprotective data on ginseng for dopaminergic neurons and intends to show aspects where neuroprotection e.g. by ginsenosides, additionally or preceding standard Parkinson therapy, could come about as a valuable contribution to slow neurodegenerative processes.

Cordyceps is a fungus used as a traditional medicine in China, Japan, and Korea. Paecilomyces (P.) japonica is a new cordyceps that was recently cultivated on silkworm pupae in Korea. The present study evaluated the toxicological effects of P. japonica in rats. Forty rats were treated with oral doses of P. japonica (0, 20, 100, or 500 mg/kg/day) for 4 weeks. Twenty additional rats were treated with 0 or 500 mg/kg/day of P. japonica for 4 weeks and then maintained for 2 weeks without treatment. Clinical signs, body weight, food and water consumption, and organ weight as well as hematology, serum biochemistry, and histopathology data were examined. Body weight gain of the group treated with 500 mg/kg/day was significantly reduced. Microscopically, karyomegaly, single cell necrosis, and mitosis were observed in the renal tubular epithelium of all treated groups. In conclusion, P. japonica caused a reduction of body weight and renal injury in rats. The no observed adverse effect level (NOAEL) of P. japonica was less than 20 mg/kg/day.
