한약재는 저장 및 유통과정에서 약 20여종의 저장해충이 발생하는 것으로 알려져 있으나 화랑곡나방(Plodia interpunctella H.), 권연벌레(Lasioderma serricorne F.), 거짓쌀도둑거저리(Tribolium castaneum H.) 등 일부 우점해충이 이들 피해의 절반이상을 차지하고 있는 것으로 파악되고 있다. 그런데 시중유통 한약재 중에는 저장해충 외에 권련침벌 등 포식성 해충이 함께 발견되고 있으나 이에 대한 조사나 연구결과는 거의 없는 상황이다. 본 연구는 한약재 저장해충의 생태네트워크를 파악하기 위하여 기존의 문헌들을 바탕으로 이들 해충의 포식관계를 조사하고 시중유통 한약재 중 비교적 해충오염도가 높은 약재를 번식이 유리한 온습도 조건에서 보관하며 해충밀도를 높인 후 자연 증식한 숙주와 포식해충의 생태를 현미경으로 관찰하였다. 국내외 문헌조사결과 권연벌레의 천적은 권련침벌, 곤충병원성선충, 쌀바구미금좀벌, 긴털가루응애 등이 밝혀진바 있고, 화랑곡나방의 천적은 보리나방살이고치벌이 그리고 거짓쌀도둑거저리의 천적은 긴털가루응애(Tyrophagus putrescentiae S.)가 확인된바 있다. 실제로 오염 한약재인 천궁, 방풍 등을 보관하는 과정에서도 권연벌레의 밀도가 높아지자 권련침벌(Cephalonomia gallicola H.)이 크게 발생하였고, 긴털가루응애는 권연벌레와 거짓쌀도둑거저리 모두에게서 발견되었다. 그러나 권련침벌의 경우 한약재를 구입할 때부터 포장지 내에 권연벌레와 함께 있는 것이 확인되었으나 긴털가루응애는 처음부터 한약재 포장 속에 있었는지 한약재 보관실험과정에서 주변으로부터 오염되었는지는 확인되지 않았다. 긴털가루응애의 발생직후 확산속도는 습도가 높을 경우 권련침벌보다 훨씬 빨랐으며 습도를 30% 이하로 낮출 경우에는 밀도가 크게 떨어졌다. Sm. Ch. Papadopoulou(2006)는 권련침벌이 한집단내 권연벌레 유충을 평균 약 20%가량 포식하는 것으로 조사하였으나 본 관찰결과 이보다 훨씬 많이 발생하였으며 권연벌레의 밀도를 90%이상 감소시킨 경우도 있었다. 본 조사를 통해 관련 천적들이 주요 저장해충의 밀도를 어떤 조건에서 얼마나 낮출 수 있는지에 관한 계량적인 연구결과는 아직 부족하나 천적으로 활용하기에는 인체 위해성 및 다른 식품 등으로의 2차오염 가능성이 있어 다소 부적합 할 것으로 판단된다.

2007년에 도입된 인삼 임의자조금제도가 앞으로 범 인삼업 계가 참여하는 의무자조금제도로 전환될 예정이다. 인삼 의무 자조금의 성공적인 조성과 운용을 위해서는 자조금 거출액을 합리적인 수준으로 책정하고 인삼 농가들의 자발적인 참여를 유도하는 것이 필요하다. 본 연구에서는 이중양분선택형 조건 부가치평가법(CVM)을 이용하여 인삼 의무자조금에 대한 농 가의 지불의사액을 추정하였으며, 주요 결과 및 시사점은 다 음과 같다. 1. 인삼 의무자조금에 대한 농가 지불의사액(WTP)의 평균 값(Mean WTP)과 중앙값(Median WTP)은 각각 117.27원/kg 과 86.81원/kg으로 추정되었다. 따라서 인삼 대표자 그룹회의 에서 논의된 인삼 의무자조금 거출액인 100원/kg 수준이 무난 한 것으로 판단된다. 2. 인구통계학적 변수가 인삼 의무자조금 납부에 미치는 영 향을 검증한 결과 자조금에 대한 인지도가 높을수록, 그리고 교육수준이 높을수록 인삼 자조금을 납부할 확률이 높아지는 것으로 나타났다. 3. 기존에 인삼 임의자조금을 납부해온 농가일수록 의무자 조금을 납부할 확률이 낮아지는 것으로 나타났는데, 이러한 결 과는 인삼 자조금의 경제적 효과에 대한 회의적인 태도에서 비롯된다. 따라서 향후 인삼 의무자조금사업의 성공적인 안착 을 위해서는 인삼 농가들을 대상으로 자조금의 도입 취지, 필 요성, 경제적 효과 등에 대해 보다 확실히 인식시킴으로써 자 발적인 참여를 유도하는 것이 필요하다.

Background : Osteoclasts are differentiated from the monocytes/macrophages of hematopoietic cells, that excessive activities of bone-resorbing giant cells leads to pathological bone diseases such as osteoporosis (contained rheumatoid arthritis and autoimmune arthritis). Therefore, it is very important to suppress loss of bone mass by deactivation of osteoclast differentiation. In this context, we evaluated for the effects of black ginseng (BG) extract on TRAP activity, proliferation and differentiation in RANKL-induced osteoclastic RAW264.7 cells. Methods and Results : The aim of this study is to figure out the potential anti-osteoporosis effects and the underlying mechanism of BG extract in RANKL-induced osteoclastic RAW264.7 cells. The ginsenoside Rg3, Rg5, Rk1 and Rh4 content of BG was increased more than Red ginseng (RG). The extracts of BG markedly reduced the activity of tartrate-resistant acid phosphatase-positive (TRAP+) multinucleated cells from osteoclastic RAW264.7 cells, without cytotoxicity. BG clearly inhibited RANKL-induced osteoclast differentiation by decreased calcitonin and TRAP (p < 0.01). Furthermore, ginseonside Rg5 and Rk1 significantly inhibited TRAP activity in formation of osteoclastic differentiation (p < 0.01). It is also found that Ginseonside Rg5 and Rk1 mixture more inhibits osteoclast differentiation activity. Conclusion : Our results suggest that Black ginseng extract has an anti-osteoporosis effects in bone disease when administered as a food supplement and has potential as a therapeutic agent for osteoporosis.

Skin reactivity calculated from irritation score in GS-E3D treated group was 0.51 and skin irritation score of no application group was 0, respectively. Skin irritancy was no response in both GS-E3D treated group and no application group. From above data, GS-E3D was identified as a non-irritant according to ICDRG guideline that skin irritation score of ‘0.00 - 0.75’ is a non-irritant. Conclusion : These results indicate that GS-E3D can be useful as a safe cometic ingredient.

Background : Pectin lyase-modified red ginseng extract (GS-E3D) is a newly developed ginsenoside Rd-enriched ginseng extract. This study was designed to investigate the acute oral and dermal toxicity of GS-E3D in rat. Methods and Results : The acute oral toxic effects of GS-E3D in female SD rats were examined at dosages of 300 ㎎/㎏ and 2,000 ㎎/㎏. In acute dermal toxicity study, 500, 1,000 and 2,000 ㎎/㎏ of GS-E3D were applied onto the shaved skin of male and female SD rats. The weights of rats were recorded at 0, 1, 3, 7, and 14 days and clinical observation were checked once a day for a period of 14 days. All rats were scarified on 14th day and complete gross examination was conducted to detect any gross change of organs after necropsy. GS-E3D did not produce orally or dermally treatment-related clinical signs of toxicity or mortality in all rats during the 14-day observation period. The oral and dermal LD50 values of GS-E3D were over 2,000 ㎎/㎏ in rat. The oral and dermal administration of GS-E3D revealed no significant change in body weight and gross pathology examination compared to control group. Conclusion : These results indicate that GS-E3D can be used as a food and cosmetic materials without critically adverse effect.

Background : Non-alcoholic fatty liver disease (NAFLD) is caused by obesity, type 2 diabetes mellitus, dyslipidemia, and genetic factors. Also, hyperinsulinemia directly promotes fat accumulation in hepatocytes. Therefore, it is very important to suppress the most common risks of NAFLD, such as obesity and insulin resistance. In this context, we evaluated for the effects of black ginseng (BG) extract on lipid accumulation inhibition and degradation in hepatocytes. Methods and Results : The aim of this study is to figure out the potential anti-lipogenic effects and the underlying mechanism of BG extract in a cellular-, type 2 diabetes mellitus (T2DM) animal model associated with NAFLD. T2DM animal used C57BL/KsJ db/db mouse (M. 6 wk, n = 56), treated with extract of BG and Red ginseng (RG) (each 100 and 900 ㎎/ ㎏/day, p.o) for 6 weeks. BG markedly reduced palmitate-induced intracellular lipid accumulation in HepG2 cells. On histology of liver tissues of T2DM animal, macrovesicular lipid droplets in cytoplasm of hepatocytes were decreased both RG and BG-treated groups. In liver tissue, BG-treated groups suppressed CCAAT/enhancer binding protein-α (C/EBP-α), sterol regulatory element-binding protein-1c (SREBP-1c) expression, and SREBP-1c mediated induction of acetyl-CoA carboxylase (ACC) and fatty acid synthase (FAS) proteins related to the induction of adipose differentiation. Futhermore, adenosine monophosphate (AMP)-activated protein kinase (AMPK) activity was significantly increased in BG-treated groups compared to RG-treated groups. It is also found that peroxisome proliferator-activated receptor-α (PPAR-α) highly expressed in BG-treated groups. Conclusion : Our results suggest that black ginseng extract has an anti-adipogenic and anti-lipogenic effects in the liver when administered as a food supplement and has potential as a therapeutic agent for obesity and T2DM induced NAFLD.

Background : Management of air temperature are known to primarily affecting on physiological properties and yield in plant. Methods and Results : The effect of air temperature on characteristics of photosynthesis and chlorophyll fluorescence in Schisandra chinensis Baillon were investigated under controlled temperature using growth chamber. Net photosyntheis rate, transpiration was measured at 1,000 μmol m-2 s-1 of photon flux density and chlorophyll fluorescence was analyzed by OJIP method. Net photosyntheis rate and transpiration rate was higher in treatment of 25℃. As results of chlorophyll fluorescence by OJIP analysis, maximum quantum yield (Fv/Fm) of photosystem II (PSII) and PIabs was higher in treatment of 25℃ which reflects the relative reduction state of PSII. But in treatment of 35℃ the relative activities per reaction center such as ABS/RC, DIo/RC were higher than in treatment of 25℃ which implied that the relative reduction of electron transport at PSI and increasement of photo inhibition at reaction center. Conclusion : This result implies that 25℃ of air temperature may be a adequate temperature to improving the efficiency of photosynthesis through controlling a photosystem in Schisandra chinensis Baillon.
