지난해 9월 보건사회부가 국민 보건을 위해 설정한 농산물중 농약 잔류허용기준이 금년 9월부터 시행에 들어간다. 그러나 이번에 보사부가 마련한 $\ulcorner$농산물의 농약잔류 검사등에 관한 처리지침$\lrcorner$에 따르면, 잔류농약이 허용 기준치를 초과한 농산물은 타용도 전환, 폐기, 수입금지 등의 조치를 시행하되, 생산판매 및 사용자(농산물을 원료로 하여 가공식품을 제조하는 자)에 대해서는 ''90년 8월까지는 경고와 동시에 특별지도, 계몽을 펴나가고 ''90년 9월부터는 식품위생법의 규정에 따라 고발조치키로 했다.

Tropical fire ant, Solenopsis geminata (Fabricius) is distributed over the tropical and temperate areas. It is a polyphagous pest attacking to various plant and causes the pain to the people doing outdoor work. So it is known for a hygienic pest to human being, especially the people doing outdoor activities. It can cause severe pain to human, even with just a bite. Of particular concern is the possibility of its settlement in this country, if it invade to the farmlands and/or forests of Jeju Island and southern part in Korea. It is listed as a regulated pest in Plant Quarantine Act of Korea. This ant is usually imported through a ship and early settled in the port area where it is already distributed. Recently its distribution is rapidly spreading into Southeast Asia and southern part of China. In Korea, it was detected the one time in 1990s, but was detected the ten times from 2000 to 2006 by an imported plant quarantine process. Therefore, we would like to provide some information on the species, including morphology, distribution, host plant, damaged symptom and its general bionomics, which will be useful data for plant quarantine process and control.

This study was conducted to determine the content of inorganic metals in botanical pills and assess the safety of mineral balance in body. Inorganic metals (Fe, Ca, Zn, Na, Mg, K, Pb, Cd, Cr) were detected in 11 kinds, 51 samples by Atomic Absorption Spectrophotometer. The average concentration of inorganic metals in botanical pills was in the order of K(7933.32 mg/kg)>Na(5848.58mg/kg)>Ca(2741.60mg/kg)>Mg(1595.34mg/kg)>Fe(353.14mg/kg)>Zn(22.49mg/kg)>Cr(3.51mg/kg)>Pb(0.24mg/kg)>Cd(0.09mg/kg). In samples, Morus and Laminaria contained a great quantity of K and Na, Acanthopanacis cortex, Eucommia ulmoides, Pinus densiflora, Lycii fructus, Allium sativum for. pekinense, and Platycode radix had much more amount of K than that of Na, in the mean time, Artemisia capillaris, Carthamus tinctorius seed, and Rubi fructus had various kinds of plenty inorganic metals.

21세기에는 인구의 폭발적 증가와 함께 가속화된 산업화로 말미암아 경지 면적은 줄고 농업 환경은 더욱 피폐해질 것으로 예상된다. 지금도 이미 화석 에너지원의 고갈로 대체 에너지 개발이 시급히 요구되고 있으며, 지구의 자연 환경 보존 목소리도 그 어느 때 보다 높다. 한마디로 식량, 에너지, 환경 문제가 새 세기에 우리가 시급히 해결해야할 과제로 주어져 있다. 이에 과학계에서는 식량 및 대체 에너지원의 공급을 증대시키고 환경을 보존할 수 있는 보편적인 수단으로 환경 친화적 유전자 변형 (GM)작물의 활용이 제시되고있다. 따라서 선진국들은 이의 기반이 되는 식물유전체 연구에 대규모 투자를 아끼지 않고 있으며, 이를 이 용한 식물 생명공학산업을 국가 전략 산업으로 집중 육성하고 있다. GM작물 제조 기술은 유용 유전자의 발굴 및 재조합, 식물세포로의 이식 및 재분화를 통한 완전한 식물체 재생, 이를 품종으로 실용화하는 단계로 구성되어 있다. GM작물은 1983년 항생제 저항성 담배가 개발된 것을 시점으로 하여, 1994년에는 연화지 연 토마토 Flaver Saver이후 지금까지 개발 실용화된 작물은 제초제 저항성 콩, 카놀라, 목화, 그리고 해충 저항성 옥수수 등이 있으며,2001년까지 세계적으로 상품화 승인을 얻은 경우는 15 작물 68품종에 이른다. 2001년 경우 GM작물 종자시장은 약 30억 달러에 달하고 있으며, 미국, 아르헨티나, 캐나다 등 세계적으로 52.6백만 ha에 이르는 면적에서 재배되었다. 그러나 GM농산물의 식품 및 환경 안전성에 대한 의구심이 일기 시작하였고, 따라서 이의 생산 및 소비에 대한 전반적 인 문제가 뜨거운 쟁점으로 부각되기도 하였다. 이 에 각국 정부는 객관적 인 안전성을 확보하기 위한 제도적인 장치를 마련하고 있으며, 아울러 과학기술자들은 더욱 안전한 형질전환 기술 개발을 도모하고 있다. 다음 세대의 GM작물은 단순한 제초제 및 병해충 저항성을 넘어서서 특정 영양 또는 건강기능성을 향상시켜 부가가치를 증가시킨 신품종 맞춤작물이 지속적으로 개발 상업화될 것이다. 따라서 고유성을 가진 유용 유전자의 대량 확보 여부가 산업적 경쟁력을 결정하게 될 것이다. 지금까지 개별 유전자 중심으로 이루어지던 유용 유전자 발굴 작업은 유전체학의 출현으로 규모가 대량화되고 그 효율이 증진되었다. 따라서 진 각국은 유용 유전자 발굴에 국가적 차원의 역량을 집중하고 있다. 그러나 우리나라는 정부와 민간의 소규모 지원으로 근근히 기술 습득 차원에 머물러 왔으며, 산업적 경쟁력의 무기가 될 고유한 유용 유전자와 형질전환 기술이 거의 없는 어려운 상황에 놓여 있다. 최근 정부가 시작한 생명공학 분야 대규모 연구지원 사업 기대를 모아 보며 이 분야 과학기술자들의 노력을 촉구한다.

In vivo genotoxic potential of isoquercetin, a plant common flavonoid, in comparison with quercetin was investigated for the DNA breakage and the clastogenicity endpoints. Male ICR mice were administered by oral gavage for 3 days with $3{\times}0.5%$ carboxymethyl cellulose (CMC), 3 ${\times}$ isoquercetin (250, 500 mg/kg/day), 3 ${\times}$ quercetin (250, 500 mg/kg/day) and 2 ${\times}$ ethyl methanesulfonate (EMS, 200 mg/kg/day). Tissues were collected 48 hours after the first treatment and within 3 hours after the last treatment. The DNA damages were evaluated using Comet assay in liver and stomach, while the clastogenicities were determined using micronucleus test in bone marrow of same animals. The treatment of isoquercetin as well as quercetin did not cause the DNA damages in liver and stomach, and not induce the frequencies of micronucleus polychromatic erythrocytes in bone marrow. In conclusion, isoquercetin as well as quercetin did not cause the DNA breakages and the chromosomal damages in vivo system in these study conditions.

The purpose of this experiment was to investigate boron deficient symptom of sugar beet. Sugar beet affected by boron deficiency was anatomized and observed by microscope and electron microscope. The sugar beet plants affected onboron deficiencyu with water culture and those of the experimental farm alike contained a small amount of boron. The symptom of boron deficiency began to show dark-brown lines at the ventral suface of the basal part of petiole and then, in the ridge of young leaf, growing point became darkened due to necrosis. The leaf blade was wrinked severely and finally the growth was stunted. The boron deficiency began with necrosis of the epidermis of the ventral surface of the basal part of petiole, and parenchyma under it. Necrosis and disintegration of the ridge of young leaf began to take place and were expanded gradually. Electron microscopic examination of boron deficient sugar beet plants revealed that chloroplasts degenerated, and appeared to contain larger amounts of starch, also observed larger number of osmophilic granules. And they peculiarly were found polyhedral crystals in the certain deficient chloroplasts.

This study was carried out to investigate the antioxidant effects of extracts from 9 species of forest plants in Korea. DPPH, ABTS, $NaNO_2$, hydrogen peroxide radical scavenging activity and reducing power activity were evaluated to measure the antioxidant activities of plant extracts. As a result, Geranium thunbergii has been identified as the most effective antioxidant resource. Also, total phenolic content was highest in Geranium thunbergii ($303.94{\pm}0.63mg\;GAE/g$) among 9 species extracts. Total flavonoid content was highest in Rosa multiflora ($24.32{\pm}0.22mg\;QE/g$) and proanthocyanidin content was highest in Vitis ficifolia ($279.00{\pm}4.58mg\;CE/g$) among 9 species extracts. In addition, the protective effect of plant extracts in $H_2O_2-induced$ human dermal fibroblast (HDF) cell systems were also assessed. Significant protective effects in $H_2O_2-induced$ human dermal fibroblast (HDF) cell systems were found in all plant extracts, especially in Geranium thunbergii. These results suggest that Geranium thunbergii could be a potential natural resource for antioxidant activity.

The currently implemented Positive List System, sales manager training, and pesticide sales record systems focus on the safety of determined pesticide use, but the proposed agrochemical pharmacist (AP) system aims accurate diagnosis and reasonable prescription. In this study, 81% of famers claimed expert assistance for purchasing and applying pesticides, and 42~86% of sales managers insisted on the strengthening expertise in diagnosis and prescription. In the institutionalization of AP, a special implementation guideline is essential to embrace the present sales managers with long experience. Sales managers of commercial and agricultural cooperatives recognize the qualifications of agrochemical pharmacists as a strategy to differentiate themselves from competitors, and increase sales through market positioning of "pesticides prescribed by trustworthy agrochemical pharmacists", not sales managers anymore.

In order to development of new denture cleaners using natural antimicrobial agents, we have investigated various species of medicinal plants for the antimicrobial activity against Streptococcus matans and Candida albicans. Citrus extract showed significant antifungal activities in a dose-dependent manner against Candida albicans. Candidasis is also a common problem affecting older adults using full denture. We also developed liquid type denture cleaner formulation using citrus extracts.
