  • Objectives : The purpose of this study was to propose appropriate strategic directions and road maps for successful achievement of programs preventing winter disease in the summer. Methods : Details on programs preventing winter disease in the summer such as clear concept, theoretical basis, current status, intervention or available prescriptions and indication/contraindication/caution were prepared through the related journal review, upon which an observational study was devised and done for simulation to find out even a trivial problem and to guarantee the safety beforehand. The experimental group was divided into 5 groups by the size of pill and the way ginger is treated; 1cm pill with ginger group, 3cm pill group without ginger, 3cm pill group dipped into ginger, 3cm pill group applying ginger to acupoints and 3cm pill group with ginger Results 1. program preventing winter disease in the summer was defined as representative winter diseases such as common cold, influenza, chronic asthma, chronic bronchitis, allergic rhinitis, emphysema, chronic gastritis and rheumatoid arthritis, and preventive care in the summer, reinforcing deficient yang qi of five viscera by using exuberant yang qi from summer heat. 2. It was based upon historically established theories which is 'nourishing yang qi in the spring and summer', 'long summer, namely rainy spell in the summer overwhelms the winter, because of earth winning water according to the five phases theory' and 'To replenish yang qi is major principle to treat winter diseases, which can be most appropriately and timely applied to the patient with deficient yang qi of five viscera inherently, especially in the three dog days of the summer, because of exuberant exterior yang qi and deficient interior yang qi in the five viscera'. 3. In the adjacent China and Taiwan, acupoint applying method in the three dog days named 'San Fu Tie' have been stirring a boom throughout the nation, in which Xiaochuan Gao was used as a basic prescription and it mainly was applied at bilateral $BL_{13}$, $_{15}$ and $_{17}$ for about 4 hours. As far as domestic current status, the necessity of adopting the above method prior to Herbal formula was also recognised, because not a few koreans have apprehension for the safety of it including medicinal herbs and are reluctant to take it any more due to negative advertisement of narrow minded doctors' association. 4. Indication of acupoint applying method in the three dog days included most of winter diseases such as common cold, influenza, chronic asthma, chronic bronchitis, allergic rhinitis, emphysema, chronic gastritis. contraindication was pregnant woman and the weak such as infants and the old. More attention was paid to grasp firmly the normal reaction following the treatment for preventing side effect and teasing blister. recommendation was also given to abstain from food inducing phlegm and dampness such as meat, shrimp and crab as well as cold drinks and foods 5. In the simulation observational study based upon the above findings following review the related articles, no blister was shown on the acupoints icluding bilateral $BL_{13}$, $_{15}$ and $_{17}$ in every experimental group during 24hr observation following the acupoint applying treatment with pills made by modified and devised prescription. At 4 hr, the effectiveness of it reached a peak showing redness and mild tenderness and there is little difference between groups 3cm pills groups regardless of the way ginger was treated. abdominal distention and growling was found in all the volunteers during the treatment at CV 8. Strategic directions and road maps : Through successful fulfillment of the program preventing winter disease in the summer, Korean traditional medicine should be integrated into mainstream national health care services. Cultural access was thought to be as important as Scientific EBM approach. First of all, To evoke potential cultural homogeneity from campaigns and press advertisement was needed for promoting public awareness about preventing winter disease in the summer by enhancing immunity via acupoint applying treatment in the three dog days, and then indigenous name as Sambokcheop, protocol, Clinical Research Form for data collection of it should be developed and prepared. Once the first step was taken this summer, through a thorough data collection and scrutinized scientific evaluation, drawbacks should be compensted for and the efficacy and safety should be substantiated.

  • The objective of this study was to identify beauty food activity of Polygala japonica Houtt., which were widely used as a folk medicinal plant to treat inflammatory diseases. Both hot water and 50% ethanol extract of P. japonica Houtt. were evaluated for their anti-oxidant, whitening, anti-wrinkle and anti-inflammatory effect based on their phenolic concentration. To measure anti-oxidant activity, four experiments were carried out. 1,1-diphenyl-3-picrylhydrazyl, 2,2-azinobis (3-ethylbenzothia-zoline-6-sulfonic acid) and thiobarbituric acid reactive substances all showed more than 80% efficacy in both hot water and 50% ethanol extract of P. japonica Houtt. and likewise antioxidant protection factor value more than 2. To investigate the whitening effect of P. japonica Houtt., the inhibition effect of tyrosinase on hot water and 50% ethanol extract was inhibited by 12.46 and 22.10%, respectively. To examine the anti-wrinkle effect, the inhibition effect of elastase and collagenase on hot water and 50% ethanol extract were inhibited by 28.28, 58.36% and 59.73, 78.90% respectively. To investigate the anti-inflammatory effect and moisturizing effect by hyaluronidase inhibitory effect, hot water and 50% ethanol extract were 35.65 and 86.80%, respectively. The result of all the above experiments show values at a concentration of $200{\mu}g/mL$, and based on these experimental results, P. japonica Houtt. can be expected as a functional material in beauty foods.

  • The purpose of this study is to determine the possibility of using Sophorae fructus as natural health food source. To accomplish this purpose, the contents of general and antioxidative nutrients of Sophora fructus were measured. The contents of carbohydrate, crude protein, crude lipid and ash are 75.9%, 16.4%, 2.41%, and 5.2%, respectively, while the calories of Sophora fructus was 337.3 kcal. Total dietary fiber was 15.07% of total carbohydrates. The percentages of water soluble dietary fiber to insoluble dietary fiber were 1.09% and 10.36%, respectively. The protein was composed of a total of 18 different kinds of amino acids. The contents of essential and non-essential amino acids were 2,310.91 mg and 5,218.52 mg. The K was the largest mineral followed by Ca, P and Mg, which means Sophorae fructus is alkali material. The contents of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids were 24.94%, 32.40%, and 32.86%, respectively. Therefore, the amount of the total unsaturated fatty acid was higher than that of any other plant. The content of vitamin C in Sophorae fructus was higher than that of any other plant, which suggests that it could increase blood elasticity. The content of rutin, which is responsible for capillary vessel permeability, was 1.78%. The contents of water soluble antioxidative materials in 1 mL of water-extracted Sophorae fructus were $4.95\;{\mu}g$ which is comparable to 1,560.96 mmol of vitamin C in antioxidant effect. The general nutrients and other antioxidatant bioactive materials in Sophorae fructus were also potential materials for good health food. It is expected that a follow up study on Sophorae fructus through developing processed food and evaluation of their functional properties would provide useful information as a source of medicinal foods.

  • Increased consumption of a polysaccharide, ${\beta}$-glucans, in foods may prevent health related problems such as cancer, cardiovascular diseases and diabetes. ${\beta}$-glucans is a fibrous polysaccharide having proven both functional and medicinal properties. Recently, the FDA recommends the consumption of oat or oat products containing a total of at least 3 grams of bea-glucans per day for health improvement. The content of ${\beta}$-glucans in barley was almost four times higher than that in oat. In this study, the physicochemical and sensory characteristics and biological properties of steamed barley bread added with ramie leaf powder was investigated. The study of sensory characteristics was performed using the Quantitative Descriptive Analysis (QDA). 30 panelists were selected among our university students. They then evaluated the different sensory characteristics, such as overall preference, color, flavor, chewiness, moistness and taste. The color and texture analyses were determined using a colorimeter and texture analyser, respectively. In the sensory, color and texture evaluation, barley bread with ramie leaf showed higher values than barley bread and wheat bread did. The physiological activities were investigated through the total phenol content and 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical scavenging activity. Hence, barley appears to be a suitable food resource for making bread. This study suggests that barley bread added with ramie leaf can be used as one of the processing methods in promoting the consumption of barley. It might also help with the improvement of barley food industry.

  • This study examined the effects of gromwell (Lithospermum erythrorhizon) extracts on the storage characteristics of Kangjung. At an increase of $0{\sim}0.25%$, there was no significant difference in the moisture content of wild and cultivated gromwell extract added to Kangjung, whereas there was a significant difference when increased to 0.5%. When compared, the occurrence of lipid oxidation among the controlled gromwell extract group stored at $60^{\circ}C$, resulted in peroxide values exceeding 40 meq/kg which is a maximum value for Hankwa within 12 hours of storage. However, at an increase of 0.25%, the cultivated gromwell extract added group reached limits within 16 hours. Furthermore, at a 0.5% increase in cultivated gromwell and 0.25% in wild gromwell, extract added groups exceeded this limit within 20 hours of storage. Gromwell added Kangjung, a fried food, showed efficiency in suppressing oxidation of fat, more so in the wild gromwell than the cultivated gromwell. In addition, efficiency in suppressing oxidation of fat increased at the 0.5% level than the 0.25% level. In conclusion, it is believed that an unused pigment resource called Lithospermum erythrorhizon, normally reserved for medicinal use, can be distributed as a safe food additive. In addition, as Lithospermum erythrorhizon is a natural antioxidant in fried foods, we believe this satisfies the demand for natural food.

  • This study was performed to develop natural spices and functional foods using Cheongung (Cnidium officinale) which is one of the Korean medicinal plants. The volatile flavor patterns of Cnidium officinale were detected by electronic nose with 6 metal oxide sensors, and the principal component analysis was carried out. The volatile flavor components of Cnidium officinale were isolated by simultaneous steam-distillation extraction with pentane and diethylether (1 : 1), and essential oils were analyzed by capillary GC and GC/MS. The free radical scavenging activity of ethanol and methanol extracts from Cnidium officinale was measured by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and compared with ${\alpha}-tocopherol$ as reference. The principal component analysis showed the difference of principal components between fresh and drying samples. Eighty-five volatile flavor components (643.64 ppm) from fresh Cnidium officinale were identified and the major components were butyl phthalide, sabinene, neocnidilide. Sixty-four volatile flavor components (218.15 ppm) from hot air dried one were identified and the major components were butyl phthalide, sabinene, 3-N-butyl phthalide. And 73 volatile flavor components (784.15 ppm) from freeze dried one were identified and the major components were butyl phthalide, sabinene, ${\beta}-selinene$. The free radical scavenging activity of methanol cold extract (500 ppm) of freeze dried Cnidium officinale was higher than other samples. And methanol and ethanol cold extracts (above 250 ppm) of freeze dried sample were higher than ${\alpha}-tocopherol$ $25\;{\mu}M$ (22.34%).

  • Ursolic acid (UA) and Oleanolic acid (ONA), known as urson, micromerol and malol, are pentacyclic triterpenoid compounds which naturally occur in a large number of vegetarian foods, medicinal herbs, and plants. They may occur in their free acid form or as aglycones for triterpenoid saponins, which are comprised of a triterpenoid aglycone, linked to one or more sugar moieties. Therefore UA and ONA are similar in pharmacological activity. Lately scientific research, which led to the identification of UA and ONA, revealed that several pharmacological effects, such as antitumor, hepato-protective, anti-inflammatory, anticarcinogenic, antimicrobial, and anti-hyperlipidemic could be attributed to UA and ONA. Here, we introduced the effect of UA and ONA on acutely barrier disrupted and normal hairless mouse skin. To evaluate the effects of UA and ONA on epidermal permeability barrier recovery, both flanks of 8-12 week-old hairless mice were topically treated with either 0.01-0.1 mg/ml UA or 0.1-1 mg/ml ONA after tape stripping, and TEWL (Transepidermal water loss) was measured . The recovery rate increased in those UA or ONA treated groups (0.1 mg/ml UA and 0.5 mg/ml ONA) at 6 h more than $20\%$ compared to vehicle treated group (p<0.05). Here, we introduced the effects of UA and ONA on acute barrier disruption and normal epidermal permeability barrier function. For verifying the effects of UA and ONA on normal epidermal barrier, hydration and TEWL were measured for 1 and 3 weeks after UA and ONA applications (2mg/ml per day). We also investigated the features of epidermis and dermis using electron microscopy (EM) and light microscopy (LM). Both samples increased hydration compared to vehicle group from f week without TEWL alteration (p<0.005). EM examination using RuO4 and OsO4 fixation revealed that secretion and numbers of lamellar bodies and complete formation of lipid bilayers were most prominent $(ONA{\geq}UA>Vehicle)$. LM finding showed that thickness of stratum corneum (SC) was slightly increased and especially epidermal thickening and flattening was observed (UA>ONA>Veh). We also observed that UA and ONA stimulate epidermal keratinocyte differentiation via $PPAR\;\alpha$. Protein expression of involucrin, loricrin, and filaggrin increased at least 2 and 3 fold in HaCaT cells treated with either $ONA\;(10{\mu}M)$ or UA $(10{\mu}M)$ for 24h respectively. This result suggested that the UA and ONA can improve epidermal permeability barrier function and induce the epidermal keratinocyte differentiation via $PPAR\;{\alpha}$. Using Masson-trichrome and elastic fiber staining, we observed collagen thickening and elastic fiber elongation by UA and ONA treatments. In vitro results of collagen and elastin synthesis and elastase inhibitory activity measurements were also confirmed in vivo findings. These data suggested that the effects of UA and ONA related to not only epidermal permeability barrier functions but also dermal collagen and elastic fiber synthesis. Taken together, UA and ONA can be relevant candidates to improve epidermal and dermal functions and pertinent agents for cosmeseutical applications.

  • World production of mushrooms has been increasing 10-20% every year. Recently, Pleurotus eryngii and P. nebrodensis are very popular as new mushroom species for cultivation. Two kinds of mushrooms, Gumji (Ganoderma) and Soji, were described in old book of Samguksagi (History of the three kingdoms; 1145) in Koryo-dynasty. Many kinds of mushrooms were also described in more than 16 kinds of old books during Chosun-dynasty in Korea. One hundred and sixty commercial strains of 25 species in mushrooms were distributed to cultivators. By the way, only 8 varieties of them have registered variety protection. Mushroom industry as important export products developed from 1960 to 1980. Production of mushrooms as food was 181,828 metric tons valued at 800 billion Korean won in 2003. Isolated and identified substances from mushrooms are promising antifungal, antiinflammatory, antitumor, antiviral (anti-HIV), antibacterial & antiparasitic, antidiabetic, immunomodulating, kidney tonic, hepatoprotective, nerve tonic, and sexual potentiator. These substances can also be used for blood pressure regulation and effective against cardiovascular disorders, hypocholesterolemia & hyperlipidemia, and chronicbronchitis. Mushroom products including pharmaceuticals, tonics, healthy beverages, functional biotransformants, and processed foods have also became available on the markets. Compost and feed can likewise be made from mushroom substrates after harvest. The mushroom industry is already one of the fastest growing investment sectors in Korea. By the way, there is a need to strain improvement for variety protection, advanced cultivation technology at low cost for growers, and control of demand and supply for marketing in order to more upgrade development of mushroom industry in the future.

  • Purpose: Medicinal herbs have recently attracted attention as health beneficial foods and source materials for drug development. Recent studies have demonstrated that extracts of Lycium's fruits and roots have a range of physiologically active substances. The extract of Lycium's leaves has been reported to have excellent anti-oxidant and anti-microbial activity, but its anti-inflammatory efficacy is not known. The chlorophyll present in the leaves can act as an anti-oxidant or pro-oxidant depending on the presence of light. Therefore, this study analyzed the anti-inflammatory effects of Lycium's fruit extract (LFE), leaf extract (LLE), and leaf extract with chlorophyll removal (LLE with CR). Methods: This study examined the inhibitory effects of LFE, LLE, and LLE with CR on pro-inflammatory mediator production as well as on the expression of iNOS and COX-2 in lipopolysaccharide (LPS)-stimulated RAW264.7 cells and BALB/c mice. Results: LFE, LLE, and LLE with CR inhibited the production of pro-inflammatory mediators (NO, $TNF-{\alpha}$, IL-6, and $IL-1{\beta}$) and the expression of iNOS and COX-2 in LPS-stimulated RAW 264.7 cells in a dose-dependent manner. Furthermore, the administration of LLE and LLE with CR inhibited the serum pro-inflammatory cytokine levels and suppressed DNA damage in BALB/c mice. In particular, LLE with CR exhibited the highest anti-inflammatory activity. Conclusion: These results suggest that the fruit and leaves of Lycium are potential therapeutic agents against inflammation.
