The green manure crops such as rye, hairy vetch and scotch oat were applied to reduce the injury by continuous cropping system(CCS) of sesame(Sesamum indicum L.) cultivation, which manure crops was sowed in latter-September or mid-October and returned to soil in the next year of May. The growth and yields were increased as 33%(65.0kg/10a) in the rotational cropping system(RCS) compared to continuous cropping system of 48.9kg/10a. In the CCS of sesame, it was increased as $10{\sim}15%$ in the green manure crop cultivation, and rye cultivation was the most effective crop to reduce the injury of continuous cropping in the green manure crops. The RCS displayed lower disease outbreak and Fussarium oxysporum density in the soil compared with the CCS, and the green manure crop showed good effect in the CCS of sesame. In the RCS, the porosity was most high in the RCS and CCS of rye cultivation, while rye and hairy vetch was effective way to reduce the injury of continuous cropping. The outbreaks of wilt disease and phytophthora blight were increased as the CCS years, however displayed lowest outbreaks of disease and the yields showed highest in the rye cultivation.

The aim of this study was to investigate the effect of a mixture of ethanol extracts of Black oryzasativa, Sesamum indicum, Oryza sativa, Rhynchosia Nulubilis, and Polygoni multiflori radix (MIXEE) on melanogenesis to develop a natural product for black hair growth. An accumulation of hydrogen peroxide ($H_2O_2$) in hair follicles, which reduces melanin synthesis, is responsible for hair graying. In the present study, MIXEE showed scavenging activity against DPPH radicals and reducing power. In addition, it reduced the cellular $H_2O_2$ level, indicating that it could inhibit oxidation and promote melanin synthesis, which was decreased by $H_2O_2$. On the other hand, it did not affect tyrosinase activity in vitro but promoted the turnover of L-DOPA into melanin. MIXEE promoted melanin synthesis at the cellular level in B16F1 cells. Furthermore, MIXEE increased the expression levels of superoxide dismutase 2 (SOD2) and SOD3 in western blot analysis. In addition, MIXEE increased the expression levels of tyrosinase-related protein (TRP)-2, which promoted melanin synthesis from L-DOPA. The results suggested that MIXEE could promote melanogenesis. Therefore, MIXEE may have potential as a natural product for promotion of melanin production and reversal of gray hair to black hair.

Seedling blight of sesame (Sesamum indicum L.) is one of the most serious diseases in Korea. This study was performed to control seedling blight in the field where sesame has been cultured for 4 years of Industrial Crop Division at the Crop Experiment Station. The pathogenic fungi of seedling blight which is known Fusarium oxysporum f. vasinfectium and Rhizoctonia solani was inoculated to the wheat media and it was spreaded on the experimental field in the concentration of 109 of wheat media mixed with 10g of fine soil. Seed sterilization was the most effective method for seedling blight control for two year experiment. Seed sterilant Benlate-T was highly effective for con trolling seedling blight with infection rate of 4% and yield of 40.7kg per 10a comparing to the control with infection rate of 96% and grain yield of 6.4kg per l0a, the other chemicals, Busan 30, Vitathiram, Captan showed good effect to control seedling blight, but less effect to the Benlate-T. The spraying treatments on leaf surface 25 days after sowing were not effective to seedling blight.

This study was conducted to ascertain the seed quality of sesame (Sesamum indicum L.) under different environmental conditions. The results were summarized as follows; 1. The sesame seeds harvested in the central noethern area of Korea showed higher linoleic acid content than did those in the southern area. 2. The linoleic acid content was highly negatively correlated with the accumulated temperature during maturity (r=-.595) and the correlation coefficient between Linoleic acid content and the accumulated solar radiation during maturity was highly significant (r=.613). Thus, the relative low temperature and high solar radiation during the maturity would be importnat factors for the increase in the linoleic acid content of sesame seeds. 3. The oleic acid content was higher in the southern area than in the central northern area. 4. The oleic acid content was highly correlated with the accumulated temperature (r=.644) and the accumulated solar radiation (r=-.456), respectively. 5. The linoleic and oleic acid are important components of sesame seeds, and these show a relative relationship to determine the oil content of the seeds. 6. The oil quality in the central northern area was superior to that in the southern area.

Objectives : There have been few studies on external treatment for itching. A clinical study was performed to evaluate the effect of a newly developed herbal ointment. Methods : A newly developed herbal ointment made from Rumex japonicus Houtt, Prunus persica(Linne) Batsch, Sesamum indicum L., and Sus scrota domestics Brisson., was given to 49 participants with itching to administer for approximately a month. Demographic characteristics, treatment experiences, symptom change, and other comments were self-reported on a pre-defined questionnaire. Results : Most frequent complaint was itching (24.01%), followed by sensitivity (19.60%), dryness(18.62%), frustration (13.72%) and insomnia (12.25%). Of 41 participants who had been given treatment for itching, around a half of them (n=21) have been treated with Korean Medicine, but all of them tried Western Medicine as well. The effect of the ointment was evaluated as excellent or good/fair (67.32%). Continuity was reported as excellent or good/fair (51.0%) and fragrance (73.44%) and color (75.48%) was reported as excellent or good/fair. Convenience, however, was assessed as good/fair (67.32%) and as inconvenient (22.4%). Conclusion : The newly developed herbal ointment seems promising for relieving itching and further research to standardize and develop this kind of ointment is warranted.

Sesame (Sesamum indicum L.) is probably the most ancient oilseed crop known in the world. Sesame seed is known for its high nutritional value and for having oil (51%) and protein (20%) content. The fatty acid composition of sesame oil is palmitic acid (7.8%), stearic acid (3.6%), oleic acid (45.3%), and linoleic acid (37.7%). Sesame oil is characterized by a very high oxidative stability compared with other vegetable oils. Two lignan-type compounds, sesamin and sesamolin, are the major constituents of sesame oil unsaponifiables. Sesamol (a sesamolin derivative) can be present in sesame seeds and oils in very small amount. Other lignans and sesamol are also present in sesame seeds and oils in very small amount as aglycones. Lipid oxidation activity was significantly lower in the sesamolin-fed rats, which suggests that sesamolin and its metabolites contribute to the antioxidative properties of sesame seeds and oil and support that sesame lignans reduce susceptibility to oxidative stress. Sesaminols strongly inhibit lipid peroxidation related to their ability to scavenge free radical. The sesame seed lignan act synergistically with vitamin I in rats fed a low $\alpha$-tocopherol diet and cause a marked increase in a u-tocopherol concentration in the blood and tissue of rats fed an $\alpha$-tocopherol containing diet with sesame seed or its lignan. The authors are reviewed and discussed for present status and prospects of quality evaluation and researched in sesame seeds to provide and refers the condensed informations on their quality.

Incidences of Phytophthora blight in plant of sesame (Sesamum indicum L.) were observed in southern sesame production areas, Gochang of Jeonbug, Yeonggwang of Jeonnam, Jinyang of Gyeongnam and Dalseong of Gyeongbug province where disease survy was conducted from July 29 to August 1, 1981. The rate of disease incidence ranged from none to $61\%$ depending upon the field observed. The causal species of the Phytophthora was identified as P. nicotianae var. parasitica (Dastur) Waterhouse based on specific pathogenicity to sesame and morphological characteristics of sporangia. Diseased plants of sesame generally showed dark discoloration on the stem leading to plant death.

Porous carbon materials synthesized from various plant derived precursors i.e. seeds of [Castor (Ricinus communis), Soap nut (Sapindus sp.), Cashew-nut (Semecarpus anacardium), Jack fruit (Artocarpus heterophyllus), Safflower (Carthamus tinctorius), Ambadi (Crotolaria juncea), Neem (Azadirachta indica), Bitter Almond (Prunus amygdalus), Sesamum (Sisamum indicum), Date-palm (Phoenix dactylifera),Canola (Brassica napus), Sunflower (Helianthus annulus)] and fibrous materials from [Corn stem- (Zea mays), Rice straw (Oryza sativa), Bamboo (Bombax bambusa) and Coconut fibers (Cocos nucifera)] were screened to make supercapacitor in 5M KOH solution. Carbon material obtained from Jack fruit seeds (92.0 F/g), Rice straw (83.0 F/g), Soap nut seeds (54.0 F/g), Castor seeds (44.34 F/g) and Bamboo (40.0 F/g) gave high capacitance value as compared to others. The magnitude of capacitance value was found to be inversely proportional to the scan rate of measurement. It is suggested that carbon material should possess large surface area and small pore size to get better value of capacitor. Moreover, the structure of carbon materials should be such that majority of pores are in the plane parallel to the plane of electrode and surface is fluffy like cotton ball.

This study was conducted to select sesame varieties with high cultural stabilities by comparing several parameters of agronomic traits under the different cultural environments. Of the six areas, Iksan and Jinju areas which showed positively larger environment index values were relatively adequate cultural conditions for sesame. At the comparison of cultural stability of agronomic traits by Eberhart and Russell regression model among sesame breeding lines, Suwon 169 showed more stable regression coefficient values to the number of capsules per plant, number of seeds per capsule and seed weight per plant, and Iksan 12 showed more stable regression coefficient values to culm length and weight per plant. At the comparison of cultural stability of yield per 10a, Suwon 169 and Iksan 12 among sesame breeding lines showed more stable respectively, deviation values of 0.99, 0.98 respectively, and more less regression deviation values of 0.074, 0.167 respectively. Therefore those breeding lines are comparatively higher stabilities to yield determining agronomic traits under the different cultural environments, and it was concluded that those two breeding lines had the possibility to recommend promising breeding lines in the future.
