  • Biological products, such as live varicella vaccine, are composed of biological substances derived from biological organisms. It is very difficult to identify these biologics' characteristics by analysis of simple physical and chemical methods alone. So the reference material is essential in order to evaluate the quality of bilogics. The 1'st national standard for varicella live vaccine was manufactured, established in 2002 and 2003, and have been used for the manufacturer's quality control and national lot release since then. As the lack of its availability and the decrease of its stability, this study was initiated by National Institute of Food and Drug Safety Evaluation (NiFDS) in 2008 to manufacture and establish the 2nd national standard for varicella live vaccine. The candidate material was manufactured from one of domestic manufacterers and the joint research of the NiFDS and manufacturers of varicella live vaccine was conducted to estimate of the reliable virus content. In the collaborative study, 3 laboratories including NiFDS performed the virus content test more than 7 times and all assay results were statistically analyzed. The mean coefficient of variation (CV) was 1.24%, and the geometric mean titre (GMT) variation range of each laboratory was low. On the basis of the results of this study, the candidate material of 2nd national standard for varicella live vaccine was assigned a potency of 4.26 log10 pfu/0.5 mL, when reconstituted in 0.7 mL.

  • Apricot Kernel, consumed as herbal medicine, contains amygdalin which generate HCN upon hydrolysis. Dyspnea was reported by ingesting large amount of apricot kernel, and neurological disorders such as tropic ataxic neuropathy or konzo were known as chronic toxicity of amygdalin. Other cyanogen containing plants, including flaxseed and almond, are consumed as food around the world. Moreover, some of them are promoted as functional food, leading to higher consumption, and posing health risk by cyanogenic components. The objective of this study was to find a method for the reduction of the cyanogenic compound, using apricot kernel as a model food. The most effective reduction was obtained by boiling the slices of the kernel for one hour in pH 1 HCl solution, showing 90% removal. However, the common process known to reduce the cyanogen contents, i.e., long incubation at the low temperature, did not show significant change in cyan concentration. Our data contribute to the safety of the plants containing cyanogenic compounds if they were to be developed as foodstuff.

  • From the tuberous root of Aconitum carmichaeli Debx.(Ranunculaceae), the main root is called as common monkhood mother root and the later root is called as the prepared aconite root. From the prepared aconite root. Looking at the processing method of the prepared aconite root, it is divided into Yeombuja (prepared aconite root processed in salt) and heuksoonpyeon (baekbupyeon) following the processing method after removing the soil and this is a way of processing the prepared aconite root without damage it. The recently produced raw prepared aconite root is easily damaged, thus it shall be preserved in salt to have the crystal shape on the surface of the prepared aconite root and store and transport in firmly solidified yeombuja condition. Therefore, yeombuja shall remove the salt before use and requires processing for use but heuksoonpyeon or baekbupyeon may use immediately. For the succession of the unique processing techniques of our ancestors, there has to be studies on the techniques. Prepared aconite root is generally used as holy medicines to cure the yang depletion syndrome, kidney-yang deficiency syndrome, and obstruction of qi in the chest syndrome. However, they are the substances with toxicity. It is contemplated that the contents of processing are broadly understood through the document on the processing method, and based on such foundation, the systematic set and proof on the documents are made along with the addition of the contemporary scientific theory and technology to develop the traditional processing technology to maximize the treatment effect and safety of prepared aconite root. In this study, the historic data and records on the processing method of latteral root of aconitum carmichaeli Debx will be rearranged to contribute to the standardization of medicinal herbs, maximization of efficacy and minimization of the side effects.

  • Soybean oil is an important source of vegetable oil for human food and nonfood applications and accounts for approximately 22% of the world's total edible oil production. Improvement of the quality and quantity of soybean seed oil constituents is one of the most important objectives in soybean breeding. The objective of this study was to identify quantitative trait loci (QTLs) that control oleic, linoleic, and linolenic acid contents in soybean. The 117 $F_{2:10}$ recombinant inbred lines (RIL) developed from a cross of 'Keunolkong' and 'Shinpaldalkong' were used. Narrow-sense heritability estimates based on a plot mean on seed weight, protein and oil content were 0.85, 0.82 and 0.81, respectively. Eight independent QTLs for oleic acid content were identified from linkage group (LG) A2, C1, D2, F, G, L, and O. Seven QTLs for linoleic acid content were located on LG D1b, E, H, I and L. Oil content was related with five QTLs located on LG C1, H, J, K, and L. Oleic, linoleic, and linolenic acid have two common QTLs on LG C1 and L. Thus, we identified major loci improving soybean oil quality.

  • The principal objective of this study was to compare and analyze the qualitative properties of MLT (mulberry leaf tea) and FMLT (fermented mulberry leaf tea) on the basis of the anti-cancer and anti-allergy activities of various extracts. The inhibitory effect against S-180 solid cancer in vivo were measured as 16.67% for FMLT and 17.78% for MLT. When the anti-allergy effects of the extracts of MLT and FMLT were evaluated, the hot water extract was shown to block histamine secretion more effectively than the ethanol extract for both groups. Furthermore, when the levels of the inflammatory cytokine of HMC-1 were measured, the ethanol extract was found to inhibit the inflammatory cytokine more effectively than the hot water extract, and the FMLT group was more effective than the MLT group.

  • Ginsenf Radix (Panax ginseng C. A. Meyer) has been traditionally used as a herbal medicine for many therapeutic or prophylactic purposes in the oriental countries such as Korea, Japan and China for at least two thousand years and also extensively studied in the modern scientific field of chemistry, biochemistry and pharmacology. The herb is now also indicated for use as tonic or a prophylactic and restorative agent for enhancement of mental and physical capacities, in case of weahess exhaustion tiredness loss of concentration, impotence, cold limbs, during illiness anuor convalescence. Ginseng is commonly used in the form of detections, extract and powderl and ginseng products, in the form of capsules tablets and drinks. And also ginseng radix has been widely traditionally prescribed as an important comuonents of manny Chinese prescriptions or alone in various diseases and for health with its different dosages. Nowadays since rinsenf can be generally classified into food or medicine in many nations, it is very difficult to give any exact desnition on the dosage, which may be of particular importance in clinical applications. In addition, the establishment of the reasonable dosage is currently of great significance to meet the demand for such wide applications. Accordingly in this review paper we summarized the dosage of ginseng on the basis of oriental medical books oriental and western pharmacopeias and modern scientific clinical data. The recent survey demonstrated that the averare dosare of finsenf is considered to be three to four grams per day unless prescribed apart, while one to two grams per day in western countries from the western viewpoint of classification of ginseng as a medicine, surrorted by the dosage of not more than one gram per day in most clinical studies. For that reason, it seems likely that the dosage in western countries is ascribed to the safety of ginseng considering side or unwanted effects. Consequently whether the differences of dosage between oriental and western countries depend on dietary habits and races should be closely investigated. Besides, further studies on the pharmacokinetics and bioavailability of ginseng components in clinical trials need to be done to decide optimum dosage of ginseng.

  • Objectives : 'Johyun' yulmoo which is a new variety of Coix lacryma-jobi var. ma-yuen Stapf sprout was developed and registered by Rural development administration in 2004. This variety was derived from the cross between single cross of Suwon-6 and Okayama and UCN300-25 as F1. It is characterized by early maturity, short plant height, a strong resistance, and a superior yield and is suitable for the central and northern regions. Accordingly, we were performed and evaluated single oral dose toxicity test of 'Johyun' yulmoo sprout (JYS) in Sprague-Dawley (SD) rats. Methods : Single oral dose toxicity test was performed using with male and female rats. Rats were divided into two groups: Group 1, vehicle-treated rats (Control); Group 2, JYS 5000 mg/kg-treated rats. JYS was orally administered to male and female rats at dose levels of 5000 mg/kg. Animals were monitored on the mortality, clinical signs, body weight changes, and necropsy findings for 14 days. groups : Group 1, vehicle-treated rats (Control); Group 2, JYS 5000 mg/kg-treated rats. JYS was orally administered to male and female rats at dose levels of 5000 mg/kg. Animals were monitored on the mortality, clinical signs, body weight changes, and necropsy findings for 14 days. Results : After oral treatment of JYS, we could not find any mortality at 5000 mg/kg. Compared with the control group, there were also no significant differences in clinical sign, weight changes, weight gain, and gross abnormalities in JYS 5000 mg/kg-treated group. Conclusions : Taken together, these results suggest that approximate lethal dose of JYS was considered as over 5000 mg/kg. Results from this study provide scientific evidence for the safety of JYS. Moreover, this study could be used as a basis for dose-setting data of the repeated dose 13-week oral toxicity test of JYS.

  • 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.

  • This study was conducted to investigate the anticancer (in vitro) and antiallergy effects of rice bran extracts. In an anticancer test using Hep3B cells and HeLa cells, water and 60% ethanol extracts of rice bran inhibited the growth of Hep3B and HeLa cell lines and morphological changes were also observed. In Hep3B cell lines, water extract of rice bran showed a higer antiproliferating effect than 60% ethanol extract. The growth-inhibitory effect against HeLa cells were 30.9% for $1,000{\mu}g/mL$, 88.8% for $3,000{\mu}g/mL$ rice bran water extract. The expressions of $Fc{\varepsilon}RI$ mRNA and c-kit in HMC-1 (human mast cell) were decreased by 60% ethanol treatment but tryptase mRNA was not changed. The extracts of rice bran inhibited histamine release from RPMC (rat peritoneal mast cell) activated by compound 48/80. Rice bran water extract showed inhibitory effect of 87% at $0.01{\mu}g/mL$ concentration and 60% ethanol extract inhibited the release of histamine by 86% at $100{\mu}g/mL$ concentration.
