Antioxidants are compounds that protect cells against the damaging effects of reactive oxygen species (ROS). Some ROS, such as superoxide and hydrogen peroxide, are normally produced in cells as by-products of biochemical reactions or as signaling molecules. When ROS-generating reactions are activated excessively, pathological quantities of ROS are released to create an imbalance between antioxidants and ROS, called as oxidative stress. Oxidative stress, which may result in cellular damage, has been linked to cardiovascular disease, diabetes, cancer, and other degenerative conditions. In humans the first line of antioxidant defence are the antioxidant enzymes, especially SOD, glutathione peroxidase (GPX), and to a lesser extent catalase, as well as the tripeptide glutathione(GSH). These enzymes will help destroy ROS(reactive oxygen species) such as hydroxyl radical, $H_2O_2$ and lipid peroxides, while GSH protects against oxidized protein. Many herbal medicines possess antioxidant properties. Herbal antioxidants may protect against these diseases by contributing to the total antioxidant defense system of the human body. Here, many herbal medicines including Ginseng, Licorice, Ligusticum Chuanxiong, Ginkgo biloba and many others was reviewed in terms of anti-oxidant efficiency related to their components.

A survey was conducted to investigate the intake pattern of health supplements and health foods by using questionnaire. The data were collected from 395 adults over middle age and analyzed with SAS program. The natural foods were most frequently taken among health supplements and health foods for health. There was no difference in pattern of health supplements or health foods intake between male and female. The item taken over 20% of subjects was health drinks, green tea, ginseng product, dietary fiber drink, honey, general tea, tonic medicine from natural foods, vitamin B, vitamin C from nutrition supplements, and Lactobacillus product from health supplements. As the main reason for taking health supplements or health foods, the male indicated recovery of fatigue and improvement of health, but the female indicated recovery of fatigue and protection or treatment on disease(p<0.001). The frequency of taking health supplements or health foods was once a day. About the effect of health foods 70.1%, of subjects answered not bad and 25% responded very helpful for their health. Twenty percent of subjects experienced side effects such as diarrhea. The results showed that the proper education program should be developed for consumer to choose suitable health supplements or health foods according to their dietary life and health condition.

The pharmacological mechanisms of most Oriental medicines have not been clearly defined in spite of their effective use in treating many diseases throughout the world. Many Oriental medicines have been used against various allergic diseases for generations, and still occupy an important place in traditional medicine in far eastern countries including Korea. It is also still unclear how Oriental drugs prevent allergic disease in vivo or in vitro models. Some Korean folk medicine inhibited the mast cell-mediated allergic reaction. This review summarizes the effective folk medicine in experimental effect on systemic or local anaphylaxis reaction. Potential anti-anaphylactic folk medicines include: Poncirus trifoliata; Siegesbeckia glabrescence; Solanum lyratum; Aquilaria agallocha; Ulmi radicis; Polygonum tinctorium; Hwanglyun-Haedok-Tang; Rehmannia glutinosa; Kum-Hwag-San; Syzygium aromaticm; Spirulina platensis; Sosiho-Tang; Sinomenium acutum; Schizonepta tenuifolia; Shini-San; Magnoliae flos; Sochungryong-Tang; Oryza sativa; Cryptotympana atrata; Salviae radix; Rosa davurica; Asiasari radix; Chung-Dae-San; Cichorium intybus; Perilla frutescens; Vitex rotundifolia; Terminalia chebula; Siberian Ginseng; Solanum melongena; Gahmi-Shini-San; Alpinia oxyphylla; Acanthopanax senticosus root; Prunella vulgaris; Allergina; Ixeris dentate; Acanthopanax senticosus stem; Tongkyutang; Salvia plebeia; Rubus coreanus; Sinpo- Tang; Dodutang; Forsythia fructus; Xanthii fructus; and Purple bamboo slat.

This study was conducted to identify useful germ plasm sources of resistance to black shank, Phytophthora. parasitica, in Nicotiana tabacum and to characterize the interaction between host plant resistance to black shank and pathogen variability. The six internationally represen-tative set of black shank resistant and susceptible tobacco genotypes and four Korean lines were tested for black shank on the field infested with P. parasitica at Chonju Experiment Station, Korea Ginseng & Tobacco Research Institute during the 1992～1997 growing season. Almost 100% of the plants of the most susceptible genotype, Ky 14, did not survive. Complete survival of (MS Ky 14 x L8)F$_1$, which is resistant to reee 0 and ausceptible to reace 1, suggests that Race 0 is the only race of the P. parasitica in this bield. Coker 371 Gold and Beinhart 1000-1 having excellent resistance to black shank could be recommended as the parental cultivars for improving black shank resistance in Korea. Data of the diseased plants showed that KB 101 and KB 110 were medium high resistant and KB 103 and KB 108 being low resistant to black shank.

Grapes(Vitis labruscana B) were fumigated with acetic acid at 20mg/liter to reduce storage decay and packaged with polyethylene film(0.03mm), then stored for 90 days at 2$^{\circ}C$. Modified atmosphere packaging reduced slightly weight loss and soluble solids content during storage. Acetic acid fumigation decreased effectively berry shattering and achieved remarkable control of rotting for storage. Two grape cultivars, 'Campbell Early' and 'Sheridan', fumigated with acetic acid had only 0.7~2.9 berries rot compared with 8.3~27.6 berries rot of cluster for grapes that were not fumigated.

The purpose of this study was to analyze consumption patterns of health functional foods (HFF) according to climacteric symptoms. Subjects were 450 middle-aged women divided into four groups by Kupperman's index. This study collected all information by self-administrated questionnaires. Higher Kupperman's index was associated with higher Menopause-specific quality of life questionnaire (MENQOL) (P<0.001) and current smoker ratio (P<0.01) as well as lower monthly income (P<0.05). Exactly 28.4% of subjects showed negative responses to effectiveness of HFF. The average number of HFF intake per person was 2.01. The main reason for consumption of HFF was treatment or prevention of disease (33.6%). The information source for buying HFF was family or relatives (40.0%). The main types of HFF were vitamins (28.2%), omega-3 fatty acid (18.6%) and red ginseng (17.3%). The intake ratio of individual approval type (Cynanchum extract and Angeli extract) was significantly higher in subjects with high Kupperman's index (P<0.001). In conclusion, these results can be used as basic data that reflect middle-aged women's needs for HFF intake according to climacteric symptoms.

Tobacco mosaic virus (TMV), TMV-common strain, causes severe damage on flue-cured tobacco in Korea. As the results, breeding programs were conducted to transfer the TMV resistance from NC567 to other cultivars. Advantage of F1, hybrid may not lie only in their heterotic value but also in directly combining of valuable dominant traits, e.g. for disease resistance, either in pairs or as groups already assembled in the two parents. A new TMV resistant flue-cured tobacco variety KF114 was developed from a cross as maternal parent MSNC567 and NC82 at the Suwon Experiment Station. KF114 was more vigorous growth characteristics in early stage than that of NC82, standard variety in Korea, and other characters were similar to those of NC82. It os high resistance to TMV, but bacterial wilt(Pseudomonas solanacerum) and black shank (Phytophthora parasitica var. nicotianae) is comparable to NC82. It should adapt well to the flue-cured production area and can reduce premature flowering under unfavorable weather conditions. Yield of KF114 is 1% to 5% higher, and nearly equal in value per KG compared with NC82. This variety, F1 hybrid, met acceptable standards for chemical and physical characteristics of cured leaf and high ranked good smoking taste by panel members in Korea Ginseng and Tobacco Research Institute.
