Objectives : This study was conducted to evaluate the antioxidative and anticancer activity of the water and ethanol extracts from medicinal herbs. Methods : Three kinds of medicinal herbs(Corni fructus, Astragalus membranaceus and Glycyrrhiza uralensis) were extracted with distilled water and 70% ethanol, and the extracts were tested for their antioxidative and anticancer activities. Results : The highest polyphenol contents of the water and ethanol extracts from medicinal herbs were 342.14 mg and 435.62 mg per 100 g of Cornus officinalis, respectively. The highest electron donating abilities (EDA) of the water and ethanol extracts from Glycyrrhiza uralensis were 88% and 91% at 1,000 ppm, respectively. The water and ethanol extracts from Astragalus membranaceus had the highest nitrite scavenging abilities (NSA) at 1,000 ppm. The highest anticancer activity of the extracts were from Glycyrrhiza uralensis against both of MDA and A549 cells. Conclusions : These results suggest that the medicinal herbs can be used as natural antioxidant to prevent oxidative damage in normal cells probably because of their antioxidant characteristics.

Objectives : The purpose of this study is to help select an appropriate word embedding method when analyzing East Asian traditional medicine texts as data. Methods : Based on prescription data that imply traditional methods in traditional East Asian medicine, we have examined 4 count-based word embedding and 2 prediction-based word embedding methods. In order to intuitively compare these word embedding methods, we proposed a "prescription generating game" and compared its results with those from the application of the 6 methods. Results : When the adjacent vectors are extracted, the count-based word embedding method derives the main herbs that are frequently used in conjunction with each other. On the other hand, in the prediction-based word embedding method, the synonyms of the herbs were derived. Conclusions : Counting based word embedding methods seems to be more effective than prediction-based word embedding methods in analyzing the use of domesticated herbs. Among count-based word embedding methods, the TF-vector method tends to exaggerate the frequency effect, and hence the TF-IDF vector or co-word vector may be a more reasonable choice. Also, the t-score vector may be recommended in search for unusual information that could not be found in frequency. On the other hand, prediction-based embedding seems to be effective when deriving the bases of similar meanings in context.

An extensive anticancer drug screening from natural resources has been carried out primarily using murine tumor model for past fourty years. Recently a new screening program from NCI, so called disease-oriented screening system. has been estabished to detect anticancer drugs that show selective growth inhibition toward variety of tissue specific human solid tumors originated from leukemia, lung, colon, CNS, melanoma, ovarian, renal, prostate amd breast. To develope the anticancer drugs from oriental medicinal herbs, we investigated the cytotoxic effects against human tumor cell panels with 23 kinds of MeOH extract of medicinal herbs. Evodiae Fructus, Meliae Toosendan Fructus, Saussureae Radix and Pharbitidis Semen showed strong activities against several tumor cell lines.

Osteoarthritis (OA) is the leading medical condition for which patients use alternative treatments including the natural remedies. The aim of this review is to describe the dietary supplements and herbal remedies most commonly used in patients with osteoarthritis with an emphasis on the efficacy and safety of these natural remedies. Glucosamine and chondroitin sulfate, two of the molecular building blocks found in articular cartilage, are the most commonly used remedies in OA treatment. Most clinical researches suggest that glucosamine and chondroitin show efficacy in reducing or improving symptoms and their ability to arrest progression of the disease or regenerate damaged cartilage. Patented formulations of both remedies are recommended by several therapeutic guidelines for use as first line background OA treatment. Reliable evidence that the combination is more effective than either agent alone is however still lacking. Several other herbs or remedies are promoted for treating osteoarthritis such as S-adenosylmethionine, methylsulfonylmethane, Harpagophytum procumbens (devil's claw), Curcuma longa (turmeric), Zingiber officinale (ginger), and capsaicin but there is no reliable evidence on long-term efficacy or safety. The clinical usefulness of these remedies is therefore rather limited currently.

The present paper reviews the findings of different research studies on the effect of natural ingredients in the Japanese quail (Coturnix coturnix japonica) diet on carcass characteristics and meat quality. The results show a relationship between the type and concentration of ingredients used in diets and carcass characteristics and meat quality. The inclusion of medicinal herbs (thyme, black seed, and mint), plants (canola), seeds (chickpea), spices (cinnamon and coriander), worms (earthworms), bee products (propolis), phytochemicals (lycopene), and edible fungi (common mushrooms) in the diet improved carcass quality characteristics compared to the control diets (basal diets). The inclusion of medicinal herbs (spearmint and green tea), spices (cinnamon), vegetables (tomato), plants (verbena and canola), seeds (marijuana), and edible fungi (oyster mushrooms) improved meat quality. In conclusion, the use of ingredients of natural origin in the diet of Japanese quail improves carcass quality characteristics and meat quality.

In order to study the natural preservation of food, sixteen kinds of medicinal plants were extracted by 80% methanol and then antimicrobial activity of the extracts was investigated against various kinds of microorganisms. The extracts of medicinal plants showed good effects of antimicrobial activity against bacteria except Bacillus cereus, Escherichia coli O-157. Especially, the extracts of Artemisia annua, Aster scaber, Solidago virganrea shower good inhibitory effects on the growth of bacteria to the cooling preservation foods, and Artemisia annua was decreased of the TMA(Trimethylamine) test. the result thus indicate that Artemisia annua, Aster scaber, Solidago fischeri extract inhibitory effects on cooling preservation foods, so that it may be potential as a natural preservatives.

We developed a dietary supplement using natural herbs and nutrients for the growth and exercise performance improvement. It called 50-22 supplement containing distilled extracts of natural herbs to remove bitterness and the addition of Vitamin B1, B6, Ca and xylitol. We investigated on the effect of 10-22 supplementation on the maximal exercise performance, IGF-1 (insulin like growth factor-1) concentration and antioxidant activity in SD rat model. In result, JR-22 supplement group was better than control group about 10％ in exercise performance test and increased about 63％ of IGF-1 concentration in blood. In addition, the oxidative damage induced by exercise was reduced by JR-22 supplementation. Therefore, we suggested that 50-22 supplementation enhanced effectively exercise performance and IGF-1 concentration and reduced to oxidative stress in muscles. Also, we analysed biochemical factors in blood for the safety of JR-22 supplement. We known that there is no change of blood lactic acid, ammonia, inorganic phosphorous ion and creatine kinase activity. (Korean J Community Nutrition 8(3) : 349∼355, 2003)

This study examines the development and management of the Herb Island in Japan, and explores influences of the herb garden on a rural community. The result suggested that the development of a herb garden can make a major impact on a rural community's econmoic stability and growth, and low-input cultivation of herbs serves to the ecosystem and soil conservation. In order to foster the herb industry in Korea, three aspcets should be considered. These are as follows. 1. Selection of suitable kinds of herbs and sites for Korean natural environment,and planning for proper landuse should be carried out first. 2. Proper policies for a herb garden to help local economy should be established. 3. Development of programs and experts on environmental education should be included in planning herb gardens in order to contribute to natural environment preservation.

Objectives : It is well known that vegetables and fruits contain minerals, including potassium, sodium and phosphorus etc. Though most oriental herbal medications are made of natural plants, western scientists suppose that they also contain certain amounts of minerals and so are injurious to kidney disease such as chronic renal disease. However, by the reason of the limitation of western medical treatment on kidney disease, many patients depend on oriental medical treatment, which includes taking oriental herbal medicine. So, in order to find out the mineral contents in oriental herbal medicine, and to establish the oriental herbal medication's safety in kidney disease, studies were performed. Methods : In this study, we analyzed 42 oriental herbs commonly used in kidney disease by the Inductively Coupled Plasma(ICP) method. Results : 1. The potassium and sodium contents of oriental herbs were 3-10 times as much as of food. 2. The mineral contents of a daily dose of oriental herbal medicine satisfied the restriction of dietary mineral in CRF, though the amount of mineral intakes by food was considered. Conclusions : The mineral contents of oriental herbal medicine are less than the limits of mineral restriction in renal failure. The yielded results, we carefully suggest that oriental herbal medicine does not induce accumulation of minerals or damage in kidney disease patients.
